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 homeowners pursue shower remodeling for a variety of reasons. Here are the most common situations we see:
Not every shower remodel project is the same. Here are the most common project types we complete in Nampa:

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.

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.

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.

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.

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.
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.
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.
Builder-grade subdivision homes with standard finishes. Similar to Meridian's housing stock — ready for finish upgrades as the homes age.
New construction with modern systems and open floor plans. Homeowners upgrade finishes 3-5 years after purchase.

Material selection affects the look, durability, and cost of your shower remodel. Here are the most popular options we install in Nampa:

The 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

Premium 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

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

Custom-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

Pressure-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

Here is how a typical shower remodel project works from first contact to final walkthrough:
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.
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.
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.
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.
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.
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.
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:
A 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.
Standard 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.
Keeping 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.
A 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.
Zero-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.
Builder-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:
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
Nampa tends to run 2-3°F warmer than central Boise in summer. HVAC sizing and window quality matter for comfort and energy costs.
Proximity to active farmland means more dust exposure for exterior surfaces. Durable, cleanable exterior finishes are preferred.
Same frost-depth and freeze-thaw considerations as Boise for foundations, exterior tile, and plumbing in exterior walls.
Newer subdivisions built from 2005 to present. Similar to South Meridian — builder-grade homes that homeowners customize and upgrade over time.

Here are the design trends we see most often in Nampa shower remodel projects:
Nampa offers some of the most affordable housing in the Treasure Valley, making it attractive for first-time homeowners and investors. Lower purchase prices mean remodeling can represent a larger percentage of home value — making strategic upgrades especially impactful for equity building. The market is strong for updated homes; buyers pay a premium for move-in-ready properties with modern kitchens and bathrooms.

Avoid these common pitfalls Nampa homeowners encounter with shower remodel projects:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
