Shower Remodel in Nampa, ID
From tub-to-shower conversions to luxury walk-in designs with frameless glass, rain showerheads, and built-in niches — we handle every detail from waterproofing to finish hardware.
Nampa is the Treasure Valley's most diverse housing market — a city where a 1940s downtown bungalow sits two miles from a 2005 subdivision ranch and a new construction townhome, where owner-occupants and rental investors share the same streets, and where the shower remodeling opportunity is as varied as the housing stock itself. Iron Crest Remodel serves Nampa homeowners across every neighborhood and every budget tier with the same foundational commitment: Schluter Systems waterproofing on every shower, precision tile installation, and honest project management that treats discovery conditions during demolition as information to communicate, not costs to hide. Nampa's value-conscious homeowners deserve quality shower remodeling that lasts — and that's exactly what we deliver at prices that make sense in Canyon County's most dynamic housing market.
Design and build the shower you have always wanted — from custom tile work to barrier-free walk-ins.

A shower remodel transforms one of the most-used spaces in your home — from a basic, builder-grade enclosure into a custom-designed space that fits your daily routine, aesthetic preferences, and long-term needs. Shower remodeling involves demolition of the existing shower or tub, plumbing rough-in for new drain and supply locations, structural preparation, waterproofing membrane installation, tile or panel application, glass enclosure installation, and fixture mounting. In the Treasure Valley, many homes built in the 1990s and 2000s have small, dark, builder-grade showers with fiberglass surrounds, poor drainage, and inadequate waterproofing that leads to hidden water damage over time. A properly planned shower remodel addresses all of these issues while creating a space that is both beautiful and built to last. The most critical element of any shower build is waterproofing — every surface that receives water must be properly membraned, sealed, and sloped to prevent moisture from reaching the framing and subfloor behind the finished surface.
Nampa's shower remodeling market is driven by three converging forces that are creating demand across the city simultaneously: the aging of a large and diverse housing stock, a rapidly appreciating real estate market that is raising buyer expectations, and a growing rental investment market where bathroom quality directly affects rental rates and tenant quality.
The housing stock dimension is particularly significant in Nampa because the city's growth history has produced a diverse inventory that no other Canyon County city replicates. Downtown Nampa and its adjacent historic neighborhoods contain some of the oldest residential construction in Canyon County — homes built between the 1890s and the 1940s whose bathrooms have original character and genuine age. The South Nampa residential corridor contains production homes from the 1970s through the 1990s whose original shower configurations have been living on borrowed time for a decade or more. Northwest Nampa contains the city's newest subdivisions, where homes built between 2000 and 2015 are now hitting the fiberglass module replacement window that Meridian homeowners know well. Each of these housing cohorts presents a distinct shower condition, a distinct budget expectation, and a distinct renovation opportunity.
The real estate appreciation dimension has fundamentally changed Nampa's renovation economics over the past decade. Canyon County homes that were worth $120,000 to $180,000 in 2013 are now worth $280,000 to $380,000, and the buyer pool entering Nampa's market brings rising expectations for bathroom quality. A buyer who is paying $320,000 for a Nampa home is comparing it to Caldwell, Meridian, and Boise alternatives at similar price points, and they're making decisions based on bathroom condition as much as price. An original fiberglass module or deteriorating tile surround is now a meaningful listing liability in Nampa's market in a way that it wasn't five years ago.
The rental investment dimension is a Nampa-specific driver that doesn't apply with the same force in Ada County's homeowner-heavy neighborhoods. Nampa has a substantial percentage of rental housing, and the investor market — local landlords with two to five properties as much as institutional investors — has been active in updating properties to compete for Canyon County's strong rental demand. A freshly tiled, properly waterproofed shower in a Nampa rental property commands meaningfully higher rent and attracts more qualified tenants, and the renovation investment pays back in rental premium within 12 to 18 months in most cases.
Canyon County's hard water is the environmental accelerant that makes all of these drivers more urgent. The Snake River Plain aquifer water that serves Nampa is heavily mineralized — hard water that accumulates calcium and magnesium deposits on tile, grout, glass, and fixture surfaces at a rate that accelerates the visual aging of any shower installation. An original installation that might last 25 years in Boise's softer water environment ages to visual failure in 15 to 18 years in Nampa's water. This accelerated timeline means that the replacement window has arrived simultaneously for a large portion of Nampa's housing stock, creating the concentrated demand for shower remodeling that Iron Crest serves across all three of the city's primary residential neighborhoods.
Nampa homeowners pursue shower remodeling for a variety of reasons. Here are the most common situations we see:
- ✓Homeowners who want to convert an unused bathtub into a spacious walk-in shower
- ✓Families who need a larger, more functional shower with better water pressure, storage, and lighting
- ✓Aging-in-place homeowners who need a barrier-free, zero-threshold shower with grab bars and bench seating
- ✓Anyone with a dated or failing shower that has grout problems, leaks, mold, or inadequate waterproofing
- ✓Homeowners who want a spa-like shower experience with rain showerheads, body sprays, and custom tile design
Not every shower remodel project is the same. Here are the most common project types we complete in Nampa:
Tub-to-Shower Conversion
Remove an existing bathtub and replace it with a custom walk-in shower. Includes new drain placement, curb or zero-threshold entry construction, waterproofing, tile installation, glass enclosure, and updated fixtures.
Walk-In Shower Remodel
Redesign and rebuild an existing shower with new tile, fixtures, glass enclosure, niches, and lighting. May include expanding the shower footprint, adding a bench, or changing the layout.
Barrier-Free / ADA Accessible Shower
Design and build a zero-threshold shower with curbless entry, linear drain, anti-slip tile flooring, grab bars, fold-down bench seating, and handheld showerhead for accessible daily use.
Luxury Shower Upgrade
High-end shower build with premium tile, rain showerhead, body sprays, thermostatic valve system, LED lighting, large-format niches, and frameless glass enclosure. Designed for a spa-like daily experience.
Shower Panel or Solid Surface Installation
Install grout-free solid surface shower panels for a clean, low-maintenance alternative to tile. Ideal for homeowners who want a fresh shower without the upkeep of grout cleaning and sealing.
Nampa has the most diverse housing stock in Canyon County, spanning from early 1900s farmhouses and bungalows to brand-new subdivision homes. This diversity means every project has unique structural and system considerations.
Pre-1950 (Downtown, older neighborhoods)
Bungalows, farmhouses, and early-century homes with plaster walls, hardwood floors, and older plumbing and electrical systems. These homes need system upgrades alongside cosmetic updates.
1960s–1980s (Northwest Nampa, established neighborhoods)
Ranch homes and split-levels with original tile, carpet, and basic finishes. Plumbing is copper or early PEX. Electrical may need panel upgrades for modern kitchen and bathroom demands.
1990s–2010s (South Nampa, newer subdivisions)
Builder-grade subdivision homes with standard finishes. Similar to Meridian's housing stock — ready for finish upgrades as the homes age.
2015–present
New construction with modern systems and open floor plans. Homeowners upgrade finishes 3-5 years after purchase.
Common issues in Nampa homes
- •Older plumbing systems (galvanized pipe, cast iron drains) in pre-1970 homes
- •Insufficient electrical panels in older homes
- •Foundation settling in some older downtown-area homes
- •Builder-grade finishes wearing out in 2000s-era homes
- •Small, closed-off kitchens in older floor plans
- •Inadequate insulation in pre-1990 construction
Material selection affects the look, durability, and cost of your shower remodel. Here are the most popular options we install in Nampa:
Porcelain Tile (Walls and Floor)
$8–$25 per sq ft installedThe most popular shower surface material. Dense, water-resistant, available in hundreds of styles including large-format, wood-look, stone-look, and mosaic options. Large-format tiles (12x24 and up) create a modern, seamless look.
Best for: Shower walls, floors, niches, and accent features
Natural Stone Tile (Marble, Travertine)
$15–$50+ per sq ft installedPremium tile option that delivers a luxurious, one-of-a-kind look. Marble hexagon floors, marble slab walls, and travertine accents create a spa-like atmosphere. Requires sealing and careful maintenance.
Best for: Feature walls, luxury shower floors, accent strips, and niche interiors
Waterproofing Membrane (Schluter Kerdi / Laticrete)
$1,500–$3,500 per shower (material and labor)Bonded waterproofing membrane system applied to every shower surface. Available as sheet membrane, liquid-applied membrane, or foam board panels. The single most critical material in any shower build — it prevents water from reaching the structure.
Best for: Every shower floor, wall, curb, niche, and bench surface — no exceptions
Frameless Glass Enclosure
$1,200–$3,500 installedCustom-measured and fabricated clear tempered glass panels and door with minimal hardware for a clean, modern look. Available in 3/8-inch and 1/2-inch glass thicknesses with various hardware finishes.
Best for: Walk-in showers where visual openness and modern design are priorities
Shower Valve and Fixture Set
$300–$1,500 per setPressure-balancing or thermostatic shower valve with trim, showerhead, and optional handheld sprayer. Quality fixtures from Moen, Delta, Kohler, or Grohe provide reliable temperature control and water delivery.
Best for: Every shower — the valve is the functional heart of the shower system
Shower material selection in Nampa is shaped by Canyon County's hard water chemistry, the diversity of its housing stock vintages, and the value-focused expectations that characterize the Nampa market across both owner-occupied and investment properties.
Schluter KERDI Waterproofing is the system Iron Crest installs on every Nampa shower project without exception. The reasoning in Nampa is identical to Caldwell and every other Canyon County market: KERDI creates a true waterproof membrane behind the tile surface, ensuring that water penetrating grout joints drains to the shower floor rather than migrating into the wall cavity and the structural framing behind it. In Nampa's older downtown homes, where framing has already experienced decades of moisture exposure from improperly waterproofed original installations, KERDI is the structural protection the project requires. In Northwest Nampa's OSB-subfloor production homes, KERDI prevents the subfloor damage that aging fiberglass modules with cracked bases have been allowing. We have never installed a shower in Nampa without proper waterproofing and have never regretted that standard.
12x24 Porcelain Tile represents the best value-to-quality ratio for Nampa shower walls. Porcelain's non-porous surface handles Canyon County's hard water significantly better than ceramic or natural stone — mineral deposits clean off porcelain without the aggressive acidic cleaners that etch stone or degrade ceramic glazes. The 12x24 format requires fewer grout joints than smaller formats, which means less grout to maintain, less grout to fail, and less grout surface area for hard water minerals to accumulate in. For rental properties and budget-conscious owner-occupied projects, 12x24 porcelain in a clean neutral tone is the specification that delivers the best long-term result per dollar invested.
Natural Stone requires specific client education in Nampa's market about Canyon County's water chemistry. Marble, travertine, and other calcium-based stones are reactive to Nampa's hard water — mineral deposits bond to stone surfaces quickly, and the acidic cleaners required to remove them also etch the stone's finish. The porcelain stone-look alternatives available today deliver 90% of the aesthetic with none of the water chemistry maintenance anxiety. For clients committed to natural stone, we strongly recommend a water softener installation before the shower project begins.
Epoxy Grout on Shower Floors is a specification Iron Crest recommends for floor applications in Canyon County due to its superior stain resistance and minimal porosity relative to cement-based grout. Epoxy grout is more demanding to install but provides longevity advantages in Nampa's hard water environment that are genuinely meaningful over a 10-to-15-year service period.
Frameless Glass Enclosures are the standard finish specification for quality Nampa shower remodels. Hardware selection leans toward brushed nickel and matte black — both of which show hard water spotting less than polished chrome — a practical consideration in Canyon County's mineralized water environment that Nampa homeowners and tenants both appreciate.
Here is how a typical shower remodel project works from first contact to final walkthrough:
1
Shower Design Consultation
We visit your bathroom, evaluate the existing shower or tub space, discuss your daily routine and wish list, and review layout options, material choices, and fixture selections. You receive a design concept and detailed estimate.
2
Design Finalization and Material Selection
We finalize the shower layout, tile design, niche locations, fixture selections, glass enclosure style, and any accessibility features. Materials are ordered and lead times are confirmed. A fixed-price contract is prepared.
3
Demolition and Plumbing Rough-In
The existing shower or tub is demolished, and we inspect the framing, subfloor, and drain condition. New plumbing rough-in is completed for the reconfigured drain location, supply lines, and valve placement. Framing modifications for niches, benches, and shower size are completed.
4
Waterproofing
This is the most critical phase. We apply a bonded waterproofing membrane system (Schluter Kerdi, Laticrete Hydro Ban, or equivalent) to every shower surface — floor, walls, curb, niches, and bench. The shower pan is sloped to the drain and tested for leak-proof integrity before tile begins.
5
Tile Installation
Floor tile is installed first with proper slope to drain, followed by wall tile, niche tile, bench tile, and any accent or feature tile. Grout is applied, cleaned, and sealed. Large-format tiles, mosaics, and accent patterns are laid out precisely per the design plan.
6
Glass, Fixtures, and Hardware Installation
The glass enclosure (frameless, semi-frameless, or framed) is measured, fabricated, and installed. Showerhead, valve trim, diverter, handheld sprayer, grab bars, towel hooks, and all hardware are mounted and tested.
7
Final Testing and Walkthrough
We run the shower for an extended test to verify drainage, water pressure, valve operation, and leak-free performance. Grout sealant is applied, and a final walkthrough ensures every detail meets expectations.
Here is what to expect for project duration when planning a shower remodel in Nampa:
| Phase | Duration | Details |
|---|---|---|
| Design and Material Selection | 1–3 weeks | Consultation, design development, tile and fixture selection, and contract finalization. Material lead times for specialty tile and glass can add 2-4 weeks. |
| Demolition and Plumbing Rough-In | 2–3 days | Remove existing shower or tub, inspect framing and subfloor, complete plumbing rough-in for new drain and supply locations, and frame any niches or benches. |
| Waterproofing | 1–2 days | Apply waterproofing membrane to all shower surfaces. Test the shower pan for leak-proof performance. This phase must be completed and verified before tile begins. |
| Tile Installation | 3–6 days | Floor tile, wall tile, niche tile, and accent tile installation. Grouting and sealing. This is typically the longest phase of active construction. Complex designs take longer. |
| Glass and Fixture Installation | 1–2 days | Glass enclosure measurement, fabrication (if not pre-ordered), and installation. Showerhead, valve trim, hardware, and accessories are mounted and connected. |
| Final Testing and Walkthrough | 1 day | Extended shower test, drainage verification, grout sealing, and homeowner walkthrough to confirm quality and function. |
Nampa range: $7,500 – $28,000
Most Nampa projects: $13,000
Nampa shower remodel costs run 10–15% below Ada County equivalents thanks to Canyon County's competitive installation labor market and lower permit fees. A basic tub-to-walk-in-shower conversion — module or original tile removal, substrate inspection and remediation, Schluter KERDI waterproofing, 12x24 porcelain tile walls and floor, semi-frameless glass enclosure, and plumbing modifications — typically runs $7,500 to $12,500 in Nampa. A mid-range project with large-format 24x24 tile, built-in niche, frameless glass enclosure, and quality fixtures runs $12,500 to $18,000. Full bathroom gut remodels in primary suites combining shower, vanity, and flooring work range from $18,000 to $28,000. Substrate remediation discovered during demolition is quoted as a separate line item after demolition and inspection. Northwest Nampa production homes carry a moderate remediation rate; downtown and South Nampa historic homes carry a higher rate, and homeowners should budget $1,000 to $3,000 as a contingency for any project in a pre-1980 home.
The final cost of your shower remodel in Nampa depends on several factors. Here are the biggest cost drivers:
Shower Size and Configuration
high impactA standard 3x4 foot shower costs significantly less than a 4x6 or 5x8 foot walk-in. Larger showers require more tile, more waterproofing, larger glass enclosures, and more labor.
Tile Selection and Design Complexity
high impactStandard subway tile on walls with mosaic floor tile is the most affordable option. Large-format tiles, natural stone, intricate mosaic patterns, accent bands, and niche detailing increase material and labor costs significantly.
Plumbing Modifications
medium impactKeeping the drain and supply lines in their existing locations is the most affordable approach. Moving the drain, adding supply lines for multiple showerheads, or converting from a tub configuration adds plumbing labor and material cost.
Glass Enclosure Type
medium impactA shower curtain is the least expensive enclosure. Semi-frameless glass doors run $800-1,500. Frameless glass enclosures with custom panels range from $1,200-3,500+ depending on size and configuration.
Accessibility Features
medium impactZero-threshold entries with linear drains, built-in bench seating, grab bar blocking, and anti-slip flooring add cost but provide essential function for aging-in-place planning.
Fixture Quality
low impactBuilder-grade showerheads and valves start around $150-300. Mid-range fixtures from Delta, Moen, or Kohler run $400-800. Premium thermostatic systems with rain heads and body sprays can exceed $2,000.
These are the real-world projects we see most often from Nampa homeowners:
Northwest Nampa Production Home — Fiberglass Module to Walk-In Shower
The highest-volume shower project in Nampa is the conversion of an original fiberglass module in a Northwest Nampa production home built between 1998 and 2012 to a custom walk-in shower. The scope follows a consistent pattern: remove the existing module and assess OSB subfloor and framing; install new cement board substrate with Schluter KERDI waterproofing on all walls and the shower floor; install a pre-sloped foam shower floor system sloped to a center drain; tile walls with 12x24 porcelain in a neutral stone-look or solid color; tile the shower floor with 2x4 or 4x4 mosaic tile; add a built-in niche; plumb a new shower valve with showerhead and hand shower; and install a semi-frameless or frameless glass enclosure. The result transforms the primary suite bathroom from its original builder-grade condition to a custom installation that looks and performs at a premium level and competes effectively in Nampa's active resale market.
Typical cost: $8,500–$14,000Timeline: 7–11 business days
Downtown Nampa Historic Home — Original Tile Replacement
Downtown Nampa's older homes contain original tile work that tells the story of every decade from the 1920s through the 1970s. These projects begin with careful demolition — removing original tile to expose the substrate beneath and assessing the framing and subfloor conditions that have been hidden for decades. Discovery conditions vary: some original installations have performed reasonably well with limited moisture damage at the caulk zone. Others reveal mortar beds that have separated from framing, soft studs from decades of steam exposure, and subfloor conditions that require partial replacement. Iron Crest documents every discovery condition photographically and presents the homeowner with a written remediation scope before proceeding. New installation begins with KERDI waterproofing over fresh cement board, followed by the homeowner's tile selection — typically a clean, timeless choice that complements the home's vintage character.
Typical cost: $9,500–$16,000Timeline: 8–13 business days
South Nampa Subdivision — Aging Tub Surround Replacement
South Nampa's 1970s through 1990s subdivision homes contain tub surround configurations that have reached the end of their functional life — original ceramic tile with grout that has failed repeatedly, caulk at the tub perimeter that fails every 18 months, and in some cases original fiberglass modules that are cracked, stained, and structurally compromised. These projects address the structural waterproofing failure as much as the aesthetic problem: full demolition to studs, KERDI installation, and a fresh tile installation built on a substrate that will protect the framing for the next 20-plus years. Homeowners who want to retain the tub for functional reasons get a properly waterproofed re-tile of the surround with a silicone movement joint at the tub interface. Homeowners who want to convert to a walk-in shower get the full conversion scope.
Typical cost: $8,000–$13,500Timeline: 7–11 business days
Nampa Rental Property — Durable Shower Replacement for Multi-Cycle Use
Nampa's strong rental market creates a distinct project type: the practical, durable shower replacement in a rental property that needs to perform reliably for multiple tenancy cycles. These projects use quality materials selected for durability and ease of cleaning rather than luxury aesthetics: 12x24 porcelain tile in a clean neutral; pre-sloped foam shower floor with 2x2 mosaic; a single built-in niche; quality but non-premium shower valve; and a semi-frameless glass enclosure with a simple door configuration. The waterproofing specification is identical to owner-occupied projects — Schluter KERDI on all surfaces. Nampa landlords who have completed Iron Crest rental shower replacements consistently report improved rental velocity and tenant retention, with the rental premium covering the project cost within 12 to 18 months.
Typical cost: $7,000–$11,500Timeline: 6–9 business days
Any Nampa Home — Accessible Shower for Aging in Place
Zero-threshold walk-in showers with built-in bench seating, blocking for future grab bars, handheld showerheads, and non-slip floor tile are among the most requested shower projects in Nampa's aging homeowner population. These projects enable long-term independence in familiar homes and are executed to the same KERDI waterproofing and tile quality standard as any Iron Crest shower project, with additional design attention to the accessibility details that make the difference between a shower that is theoretically accessible and one that is genuinely safe and comfortable for everyday use. Blocking for future grab bar installation is installed in every project at the waterproofing phase — retrofitting blocking after tile is installed requires opening finished walls.
Typical cost: $8,500–$14,000Timeline: 7–10 business days
Problem: Leaking shower with water damage behind walls and under the floor
Solution: We demolish to studs, inspect and repair all water-damaged framing and subfloor, and rebuild with a proper waterproofing membrane system that prevents future moisture intrusion.
Problem: Small, dark shower that feels cramped and uninviting
Solution: We expand the shower footprint where possible, use light-colored large-format tile to open up the space, install a frameless glass enclosure for visual openness, and add recessed LED lighting for a bright, spacious feel.
Problem: Outdated fiberglass or acrylic shower surround
Solution: We remove the old surround, inspect the substrate, install proper waterproofing, and build a custom tile shower that transforms both the look and feel of the space.
Problem: Poor water pressure and single-showerhead limitation
Solution: We evaluate your water supply capacity and install a pressure-balancing or thermostatic valve system with options for rain showerheads, handheld sprayers, and body jets — significantly improving the shower experience.
Problem: Mold and mildew in grout joints and silicone seams
Solution: We use mold-resistant grout, properly sealed tile joints, and premium silicone caulk at all change-of-plane transitions. A properly waterproofed shower with adequate ventilation prevents mold from developing behind the finished surface.
Nampa shares the Treasure Valley's semi-arid climate. Canyon County locations may be slightly warmer in summer and experience more wind than Ada County locations closer to the foothills.
Summer Heat
Nampa tends to run 2-3°F warmer than central Boise in summer. HVAC sizing and window quality matter for comfort and energy costs.
Agricultural Dust
Proximity to active farmland means more dust exposure for exterior surfaces. Durable, cleanable exterior finishes are preferred.
Freeze-Thaw
Same frost-depth and freeze-thaw considerations as Boise for foundations, exterior tile, and plumbing in exterior walls.
South Nampa
Newer subdivisions built from 2005 to present. Similar to South Meridian — builder-grade homes that homeowners customize and upgrade over time.
Common projects in South Nampa:
- •Kitchen upgrades replacing builder-grade finishes
- •Bathroom remodels with tub-to-shower conversions
- •Flooring replacement throughout
- •Deck and patio construction
Northwest Nampa
A mix of established neighborhoods with homes from the 1970s-2000s. Some areas are seeing significant investment and revitalization.
Common projects in Northwest Nampa:
- •Full kitchen renovations in 1970s-1990s homes
- •Bathroom remodels addressing outdated fixtures and tile
- •Home additions for growing families
- •Whole-home updates bringing older homes to current standards
Downtown Nampa
The historic downtown core with older homes, some dating to the early 1900s. A revitalizing area with a mix of renovation and new construction.
Common projects in Downtown Nampa:
- •Historic home renovations preserving character while updating systems
- •Kitchen remodels in homes with small, outdated layouts
- •Bathroom remodels replacing original plumbing and fixtures
- •ADU construction for rental income in the revitalizing downtown area
Every Nampa neighborhood has different housing stock, homeowner priorities, and project considerations. Here is what shower remodel looks like in each area:
Downtown / Historic Nampa
Downtown Nampa's residential neighborhoods contain Canyon County's most architecturally varied housing stock — homes built from the 1890s through the 1950s in every style from Victorian to Craftsman to mid-century ranch, many of which have never had their original bathrooms substantially updated. Shower remodels in these homes require the careful approach that age demands: thorough assessment of original construction conditions before committing to scope, attention to architectural character in tile selection, and management of the structural discoveries that opening walls in 80-to-130-year-old construction almost always produces.
The discovery rate for structural moisture damage behind original tile in downtown Nampa is the highest in the city's market. Pre-war construction in Nampa used mortar-bed tile setting over metal lath on wood framing — a system that was durable but relied on grout and caulk as the primary water management layer. After decades of thermal cycling and use, grout cracks, caulk fails, and water finds its way into the framing. By the time a downtown Nampa homeowner calls for a shower remodel, the structural damage behind the tile is typically several years old and often more extensive than the surface suggests.
Design considerations in downtown Nampa benefit from an appreciation of the home's era. A Craftsman bungalow or Arts-and-Crafts two-story carries visual context that rewards thoughtful tile selection — clean subway tile, handmade-look ceramics with slight surface variation, hex mosaic floors in matte finishes. These choices honor the home's character without being a literal reproduction of original materials, and they translate well to listing photographs when the home eventually sells in Nampa's increasingly design-aware buyer market.
South / Southeast Nampa
South Nampa's residential corridors contain the city's mid-century and late-century housing stock — the 1960s through 1990s ranches and modest two-stories that represent Nampa's largest residential inventory segment. Shower remodels in this area are the volume center of Iron Crest's Nampa business: practical projects driven by genuine need, with outcomes that dramatically improve daily function for homeowners who have been managing aging bathrooms for years.
The original tub-surround configurations in South Nampa's older homes — whether original ceramic tile or replacement fiberglass — have almost uniformly reached end-of-life. The structural condition behind failing tub surrounds is consistently more degraded than visual inspection suggests, and demolition almost always reveals moisture damage that should have been a renovation trigger years earlier. We treat the substrate remediation phase of South Nampa projects with the same thoroughness as the finish work, because the quality of the waterproofing and substrate preparation determines how long the new installation lasts in Canyon County's hard water environment.
South Nampa homeowners also tend to be pragmatic about the resale value conversation. Canyon County's appreciation has created equity positions that make strategic upgrades financially sensible, and real estate professionals in this market consistently report that updated primary bathrooms are among the most effective differentiation tools for listings in the $280,000 to $360,000 price range.
Northwest Nampa
Northwest Nampa is the city's newest residential corridor — neighborhoods built primarily between 1998 and 2015 where the dominant shower condition is the aging fiberglass or acrylic module that came standard with production construction and is now hitting its replacement window. The concentration of homes in this vintage creates the same predictable demand pattern that defines Meridian's South Side market: homeowners who bought production homes 15 to 20 years ago and are now dealing with cracked module bases, crazed surfaces, and the soft subfloor conditions that module drainage failures produce.
Northwest Nampa homeowners are generally motivated by a combination of the structural problem (the cracked module base and soft subfloor) and the aesthetic problem (the yellowing, crazed surface that no amount of cleaning restores). These are the projects where the before-and-after transformation is most dramatic — a yellowing module replaced with a custom large-format porcelain shower with frameless glass changes the primary suite bathroom's entire visual register in a way that homeowners consistently describe as one of the most impactful renovations they've made to their home.
The discovery rate for subfloor damage in Northwest Nampa is meaningful — OSB subfloor in early-2000s production homes, combined with 20-plus years of any module drainage failures, produces compromised subfloor conditions at a rate that makes the contingency budget line more than a formality. Iron Crest communicates a $1,000 to $2,500 contingency range for subfloor remediation in every Northwest Nampa shower proposal.

Nampa's shower remodel market differs from the rest of the Treasure Valley in ways that reflect the city's unique combination of housing diversity, rental market scale, and Canyon County's hard water environment.
The housing diversity is the most consequential difference. No other Treasure Valley city concentrates as many distinct housing vintages and types within a single market. Downtown Nampa's pre-war historic stock, South Nampa's mid-century and late-century production homes, and Northwest Nampa's post-2000 subdivisions represent three distinct shower remodel scenarios that coexist in the same city. This diversity means that Iron Crest's Nampa experience is broader than our experience in any single-vintage market — we have developed the full range of technical approaches and design vocabularies that Nampa's housing stock demands.
The rental investment market scale is a genuine Nampa differentiator. A significantly higher percentage of Nampa's housing stock is rental-occupied compared to Ada County communities, and the investor community's renovation decisions are driven by rental economics rather than personal use preferences. Shower remodeling specifications for rental properties — durable materials, practical maintenance requirements, tenant appeal without luxury excess — differ meaningfully from owner-occupied primary suite specifications. Iron Crest's Nampa team is experienced delivering both categories within the same project when investment properties include both rental units and owner-occupied primary suites.
Canyon County's hard water is the environmental differentiator that shapes every material specification decision in Nampa. The same project executed in Boise and in Nampa should use different grout specifications, different fixture finish recommendations, and different client maintenance guidance because the water chemistry environments are materially different. Contractors who apply Ada County specifications without adjustment to Canyon County projects are delivering results that will look older sooner than they should.
Shower remodeling in Nampa involves permit, water quality, and contractor considerations specific to Canyon County's regulatory and environmental environment.
City of Nampa building permits are required for shower remodels involving plumbing modifications. Any tub-to-shower conversion requires a plumbing permit from the City of Nampa Building Department, covering the drain relocation, shower valve rough-in, and any supply line modifications. Permit fees in Nampa are among the lowest in the Treasure Valley — typically $80 to $250 for residential plumbing permits — and inspection scheduling through the Nampa Building Department is generally efficient. Iron Crest manages all permit applications and inspection coordination as an included service.
Canyon County water quality requires specific material specifications for Nampa showers. Nampa's water supply tests for high total dissolved solids — primarily calcium and magnesium carbonate — that accelerate grout degradation, compromise silicone caulk adhesion, and bond to tile and glass surfaces. We specify epoxy grout in floor applications, premium sanded grout with penetrating sealer in wall applications, and high-performance neutral-cure silicone at all movement joints. We provide every Nampa client with a written water quality maintenance protocol covering glass squeegee habits, grout sealing schedules, and calcium deposit management appropriate to Canyon County's water chemistry.
Asbestos considerations are relevant for Nampa homes built before 1980. Downtown Nampa's pre-war and post-war housing stock has a meaningful probability of containing asbestos-containing materials in floor tiles, mastic adhesives, and joint compound. We conduct asbestos assessments on every pre-1980 project before demolition planning begins and coordinate licensed abatement when needed.
Contractor quality variation in Canyon County is a legitimate concern for Nampa homeowners. The competitive pricing environment attracts contractors who skip waterproofing membrane installation to reduce project cost. A Nampa shower installed on cement board without KERDI relies entirely on tile and grout to manage water — and grout in Canyon County's hard water environment fails faster than in softer-water markets. Ask every bidder for their specific waterproofing membrane specification and be skeptical of any contractor who cannot name a specific product.
Shower remodeling in Nampa delivers investment returns shaped by Canyon County's rapid appreciation and the dual-market dynamic of owner-occupant and rental investment demand.
Canyon County's real estate appreciation over the past decade has transformed the renovation economics for Nampa homeowners. Homes that were worth $120,000 to $180,000 in 2013 now hold value at $280,000 to $380,000 in most Nampa neighborhoods. At these value levels, bathroom quality has become a meaningful factor in buyer and renter decision-making — a change that has fundamentally improved the return on bathroom renovation investment.
For owner-occupied properties, the specific ROI numbers in Nampa's market: a mid-range primary suite shower conversion costing $11,000 to $15,000 typically contributes $14,000 to $20,000 in buyer-perceived value based on Canyon County comparable sales. This 1.2x to 1.4x return is consistent with national renovation ROI data and is well-supported by local real estate professional feedback. Homes listed with "remodeled primary bath" in the MLS description consistently sell faster and with fewer buyer concession requests in Nampa's market.
For rental investment properties, the return calculation is different but equally compelling. A $9,000 to $12,000 shower replacement that generates a $100/month rental premium pays back in 90 to 120 months — but the real return is the combination of rental premium, reduced maintenance costs, improved tenant quality, and reduced vacancy that updated bathrooms deliver. Nampa investors who have updated bathrooms in their rental portfolios consistently report improved overall property economics that exceed the direct rental premium calculation.
For long-term owners with no near-term transaction plans, the quality-of-life and structural protection arguments are the investment case: eliminating the maintenance anxiety of a failing shower, improving the daily experience of the home's most-used room, and preventing the structural damage that continued use of a leaking shower would cause. The structural remediation cost that results from ignoring a failing shower for five additional years consistently exceeds the cost of the shower remodel that would have prevented it.
Avoid these common pitfalls Nampa homeowners encounter with shower remodel projects:
Mistake: Tiling over an original tub surround without demolition to address waterproofing
Better approach: Tile-over-tile in a Nampa shower buries structural moisture damage — often present for years before the homeowner calls — and adds weight to a compromised substrate. The new tile cracks within three to five years as the failing substrate continues to move. Full demolition to studs, substrate inspection and remediation, KERDI installation, and fresh installation on a solid base is the only approach that produces a lasting result. The cost difference between doing it right and doing it over is always greater than the cost of doing it right the first time.
Mistake: Skipping the waterproofing membrane to stay under a budget number
Better approach: In Nampa's competitive Canyon County market, waterproofing membrane installation is sometimes omitted from low bids. Cement board without a membrane is not waterproof — water that penetrates grout reaches framing directly. In Canyon County's hard water environment, grout fails faster than in softer-water markets, making the KERDI membrane more important, not less. The $400 to $600 material cost of proper waterproofing is the most defensible specification in any shower project budget. Ask every bidder specifically what waterproofing membrane they intend to install.
Mistake: Choosing natural stone tile without accounting for Nampa's hard water
Better approach: Marble and travertine are legitimate choices in soft-water markets. In Nampa, where water hardness runs 300 to 500 ppm, natural stone in a shower becomes a maintenance burden. Calcium deposits bond to stone surfaces quickly and the acidic cleaners required to remove them etch the stone's finish. Current porcelain stone-look products deliver 90% of the aesthetic with none of the water chemistry anxiety. For clients committed to natural stone, we require a water softener installation before the shower project begins.
Mistake: Not budgeting for substrate remediation in Northwest Nampa production homes
Better approach: Every Northwest Nampa shower remodel involving an original fiberglass module should include a contingency budget for subfloor remediation. The rate at which OSB subfloor damage is found in these homes — where 20-plus years of thermal cycling and any module drainage failures combine — is high enough that treating it as a surprise rather than a planned contingency creates frustrated homeowners and strained contractor relationships. Iron Crest communicates a specific contingency range ($1,000 to $2,500) in every Northwest Nampa shower proposal and explains the discovery conditions that trigger it.
Nampa is Canyon County's largest city and one of the most diverse housing markets in the Treasure Valley. The city has homes dating from the early 1900s through brand-new construction, creating a wide range of remodeling opportunities. Nampa homeowners tend to prioritize practical, value-driven upgrades — functional kitchens, updated bathrooms, improved energy efficiency, and added living space. The lower median home price compared to Ada County cities means Nampa homeowners are often more budget-conscious, but they still want quality work that improves daily life and holds up over time. Canyon County's permit process is straightforward, and Nampa's Building Department is responsive to residential projects.

What makes a Nampa shower remodel different from one in Meridian or Boise?
Three things distinguish Nampa shower remodels from Ada County equivalents. First, Canyon County's hard water — running 300 to 500 ppm total dissolved solids compared to Boise's softer supply — accelerates calcium buildup on tile, grout, and glass and requires specific material specifications: epoxy grout on floors, porcelain over stone, brushed over polished hardware finishes. Second, Nampa's housing stock diversity — pre-war downtown homes, mid-century South Nampa ranches, and post-2000 Northwest Nampa production homes — creates a wider range of discovery conditions during demolition than more uniform markets, requiring a contractor who can navigate each vintage. Third, Nampa's rental market scale means that many shower remodels are investment-property decisions with rental economics driving specifications rather than personal preference — a different optimization than an owner-occupied primary suite.
Is a shower remodel a good investment in Nampa's rental market?
Consistently yes. Canyon County's rental demand is strong, and bathroom quality is among the top three factors that tenants cite when choosing between comparable rental properties. A freshly tiled shower with a clean glass enclosure in a Nampa rental property commands a rental premium of $50 to $150 per month compared to an equivalent property with a dated or failing original shower — a premium that pays back the remodel investment within 12 to 18 months at typical Nampa rental rates. Beyond the direct rental premium, updated bathrooms reduce tenant turnover by making the property more attractive to retain, and they significantly reduce the maintenance calls and repairs that aging original showers generate in a rental context.
How do I know if my Northwest Nampa production home shower needs replacement versus repair?
For Northwest Nampa production homes with original fiberglass modules built between 1998 and 2015, the answer is almost always replacement rather than repair. The crazed, yellowing surface of an aged fiberglass module cannot be restored to an acceptable appearance regardless of how much effort is invested in cleaning or refinishing. More importantly, base cracks at the drain fitting — the most common failure point — allow water infiltration into the OSB subfloor beneath that cannot be addressed without removing the module. If your shower floor feels soft or spongy near the drain, if the base is visibly cracked, or if the surface has developed the characteristic crazing of aged fiberglass, replacement is the right economic decision. Repair costs on a module that has structural base failures typically run $1,500 to $3,000 for two to five years of additional service life; a proper replacement with KERDI waterproofing costs $8,500 to $14,000 and lasts 25-plus years.
How long does a Nampa shower remodel take?
Most Nampa shower remodels take 7 to 11 business days. The day-by-day sequence: 1 to 2 days for demolition and substrate inspection, 1 day for any subfloor or framing remediation if needed, 1 day for KERDI installation and cure, 2 days for tile work with proper cure times between floor and wall tile sequences, 1 day for grouting, and 1 to 2 days for glass installation after fabricated panels arrive. We provide the specific project schedule in writing before work begins and communicate any adjustments within 24 hours of a demolition discovery that changes the timeline.
What is the most important thing to look for in a Nampa shower contractor?
Verify Idaho contractor licensing and insurance first — Canyon County's competitive pricing environment attracts contractors who are not properly licensed or insured. Beyond licensing, ask specifically: what waterproofing membrane will be installed (KERDI or equivalent named product, not cement board alone), will a City of Nampa plumbing permit be pulled for plumbing modifications, and what is the written protocol for communicating substrate damage discovered during demolition. A contractor who cannot answer these questions clearly, or who proposes to tile over an existing surround without demolition, is not the right choice for a Nampa shower remodel.
How much does a shower remodel cost in Boise?
A shower remodel in the Boise area typically costs $6,000-12,000 for a standard tub-to-shower conversion with tile, $10,000-18,000 for a mid-range custom walk-in shower, and $18,000-30,000+ for a luxury shower with premium tile, frameless glass, and multi-head fixtures.
How long does a shower remodel take?
A typical shower remodel takes 2-3 weeks from demolition to completion. Simple tub-to-shower conversions with panel systems can be faster. Complex custom tile showers with specialty glass take longer. Design and material ordering before construction adds 2-4 weeks.
Is a walk-in shower better than a bathtub?
Walk-in showers are preferred for daily use, accessibility, and modern design. However, having at least one bathtub in the home is recommended for families with young children and for resale value. Many homeowners convert a secondary tub to a shower while keeping one tub elsewhere.
What is the most important part of a shower remodel?
Waterproofing. Every square inch of the shower — floor, walls, curb, niches, and bench — must be properly membraned to prevent water from reaching the framing and subfloor. Proper waterproofing prevents leaks, mold, rot, and structural damage that are extremely costly to repair.
Can you make a shower accessible without it looking institutional?
Absolutely. Modern accessible shower design uses curbless entries with linear drains, decorative grab bars in matching finishes, teak fold-down benches, and the same premium tile and glass as any custom shower. The result is a beautiful shower that happens to be accessible.
What tile is best for shower floors?
Small mosaic tiles (2x2 or penny rounds) are the traditional choice because they conform to the shower pan slope and provide grip with many grout lines. Large-format tiles with linear drains are increasingly popular for a modern, seamless look but require precise slope and installation.
Do you handle the plumbing for a shower remodel?
Yes. We coordinate all plumbing work through licensed plumbers. This includes drain relocation, supply line modifications, valve installation, and fixture connections. All plumbing work is permitted and inspected per local code requirements.
