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.
Caldwell 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 Caldwell:
Tub-to-Shower Conversion

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

Caldwell has a mix of historic downtown homes, mid-century construction, and newer subdivision development. Older homes often need comprehensive updates while newer homes benefit from finish upgrades.
Pre-1960 (Downtown)
Older bungalows and farmhouse-style homes with vintage character but aging systems. Plumbing, electrical, and insulation often need updating alongside cosmetic work.
1970s–1990s
Ranch homes and early subdivision construction with standard finishes reaching end of life.
2000s–present (South Caldwell)
Newer builder-grade homes with modern systems but standard finishes that homeowners upgrade over time.
Common issues in Caldwell homes
- •Aging plumbing and electrical in pre-1970 homes
- •Small kitchens with inadequate storage and counter space
- •Outdated bathrooms with original fixtures
- •Poor insulation in older construction
- •Builder-grade finishes wearing out in 2000s homes
Material selection affects the look, durability, and cost of your shower remodel. Here are the most popular options we install in Caldwell:
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
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 Caldwell:
| 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. |
Typical range: $6,000 – $30,000+
Most projects: $10,000–$18,000
The final cost of your shower remodel in Caldwell 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.
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.

- ●Niche placement and sizing — position shower niches at a usable height (typically 48-60 inches from the floor), sized to fit standard product bottles, with tile that complements or contrasts the main wall tile
- ●Showerhead height and placement — rain showerheads should be at least 80 inches high; handheld brackets should be reachable while seated on a bench if applicable
- ●Tile layout planning — dry-lay tile patterns before installation to center patterns, plan cut tiles at edges, and verify grout line alignment across walls and floors
- ●Drain location and type — center drains work for standard showers; linear drains allow large-format floor tile and enable curbless entries for accessible design
- ●Lighting — recessed LED downlights rated for wet locations provide essential illumination; consider a lighted niche or accent lighting for a premium touch
- ●Ventilation — ensure your exhaust fan is rated for the bathroom's cubic footage; inadequate ventilation is the primary cause of mold and moisture damage in showers

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.
How do I keep my new shower looking good long-term?
Use a daily shower spray to prevent mineral and soap buildup, squeegee glass after each use, and reseal grout annually. We use premium grout and silicone that resist mold and staining, and our waterproofing system ensures the structure stays dry and damage-free behind the tile.
