Shower Remodeling in West Boise
Tub-to-shower conversions, fiberglass-stall removal, and walk-in builds in 1990s–2000s West Boise primary bathrooms — properly waterproofed showers that escape the era's signature look.
Shower remodels in West Boise are universally about replacing the original fiberglass shower stall that defined the 1990s-2000s subdivision primary bathroom. The original West Boise primary bath came with a corner jetted tub adjacent to a fiberglass shower stall — the entire wet zone was 70–90 sq ft of dated builder-grade design. The shower component (typically a 36"×48" fiberglass insert) is the most-replaced single feature in West Boise primary baths. Replacement options range from same-footprint walk-in shower with tile and glass enclosure, to oversized walk-in shower spanning the full former wet zone (after jetted tub removal), to full primary bath spa conversion. Iron Crest builds West Boise showers regularly.
Shower remodels in West Boise homes vary by what era of bathroom you're working in.
1985–1995: First subdivision wave
Original primary bathrooms with corner jetted tub adjacent to 36×48 or 36×36 fiberglass shower stall, oak vanity, beige tile floor and tub deck. Plumbing copper, drains cast iron. Wall framing modern stud spacing. Demolition straightforward.
1995–2005: Expansion era
Slightly larger primary baths (90–120 sq ft) with same fiberglass-shower-and-jetted-tub configuration. Sometimes early-tier tile-walk-in instead of fiberglass stall. Layout consistent.
2005–2015: Late-expansion era
Fiberglass-shower era ended. Original showers transitioned to tile walk-in with frameless glass. Most need waterproofing rebuild for current spa-tier expectations but base layout works.
2015–present: Newest construction
Already-modern showers with curbless designs and frameless glass. Replacement demand low.
West Boise shower projects fall into recognizable shapes shaped by the dominant fiberglass-shower-stall configuration.
1. The Fiberglass-Stall Replacement — same-footprint walk-in shower
Remove fiberglass shower stall, replace with curbless walk-in shower in same footprint (slab porcelain walls or large-format porcelain, frameless glass enclosure, polished chrome thermostatic trim, rain head and hand shower). Tub remains. Lower-cost approach for owners who use the tub.
Target homes: West Boise primary baths where the household uses the tub. Permit: plumbing permit; building permit for waterproofing.
2. The Tub-and-Stall Replacement — oversized walk-in shower
Remove both jetted tub and adjacent fiberglass shower stall, replace entire wet zone with single oversized walk-in shower (60–72 inches wide, full slab porcelain walls, frameless glass enclosure, multi-head system, integrated tile bench). Eliminates tub function but provides spa-tier shower experience.
Target homes: West Boise primary baths where the household doesn't use the tub. Permit: plumbing and building permits.
3. The Curbless Walk-In with Multi-Head System
Premium-tier walk-in shower with multiple shower heads — rain head + hand shower + body sprays — plus integrated shelving, tile bench, niche, possibly steam-shower function. Heated floor extending into shower.
Target homes: Premium West Boise primary baths. Permit: plumbing and building permits.
4. The New Walk-In in a Remodeled Bathroom — fresh build
Building walk-in shower as part of broader bathroom remodel where bathroom is being gutted. Lower marginal cost than standalone shower remodel.
Target homes: West Boise homes doing comprehensive primary bath remodels. Permit: full bath permit suite.
5. The Aging-in-Place Curbless Shower
Walk-in shower designed for full mobility-impaired access: curbless entry, 60″ width minimum, wall-mounted bench, blocking installed for grab bars, hand-shower on slide bar, anti-scald thermostatic valve, slip-resistant floor tile rated for accessibility.
Target homes: West Boise owners 55+ planning to age in place. Permit: building and plumbing permits.
The West Boise spans roughly two square miles with distinct sub-neighborhoods, each with its own remodeling personality.
Five Mile / Maple Grove corridor
The western edge of Boise along Five Mile Road and Maple Grove Road, with subdivision waves from the late 1980s through the early 2000s. Single-family homes typically 1,800–2,800 sq ft on 60'–90' frontage lots with attached two-car garages. The most homogeneous Boise housing — recognizable production-builder aesthetics, oak-cabinet kitchens, beige interior palettes from original construction.
Cole Road / Ustick Road area
The northern reach of West Boise centered on Cole Road and Ustick Road. Mix of 1990s subdivision homes and 2000s-2010s newer construction. Larger lots than the Five Mile corridor (typically 0.20–0.30 acre), more architectural variety, mature street trees that distinguish the streetscape.
Cloverdale / Eagle Road corridor
The transitional zone between Boise and Meridian along Eagle Road and Cloverdale Road. Predominantly 2000s and 2010s construction with newer subdivisions still being completed. Larger homes (2,500–3,800 sq ft) on slightly larger lots, often with HOA architectural review and modern community amenities.
Ten Mile / Linder Road area
The far western edge of Boise approaching Meridian. Mostly 2005-2015 construction with active development continuing. Family-oriented community feel with strong school district draw. Homes typically 2,200–3,400 sq ft, modern construction with already-current finishes from original construction.
Mountain View / Boise Bench-adjacent West Boise
The southern reach of West Boise transitioning toward the Bench. Mix of 1980s subdivision homes and earlier 1970s development. Lower price point than the central or northern West Boise areas, with strong remodel demand for kitchen and bathroom updates on aging builder-grade interiors.
Original West Boise (pre-1985)
The earliest West Boise streets, predating the major 1990s subdivision wave. 1970s and early-1980s ranches and split-levels on irregular lots. Some homes are pre-1978 (EPA RRP applies for any work involving paint disturbance). Original wood lap siding, sometimes aluminum siding from later updates, original wood double-hung windows.
Shower pricing in West Boise reflects the substantial fiberglass-stall removal scope and elevated finish expectations.
West Boise shower remodeling ranges
New shower in remodeled bathroom (incremental) (marginal cost above bathroom remodel base): $14,000–$24,000 / aligned with bath remodel
Fiberglass-stall replacement (tub kept) (remove fiberglass stall, install walk-in shower in same footprint, keep tub): $22,000–$36,000 / 5–7 weeks
Aging-in-place curbless (universal-design fixtures, blocking, premium materials): $28,000–$42,000 / 6–8 weeks
Tub-and-stall replacement (oversized walk-in) (remove both jetted tub and fiberglass stall, single oversized walk-in): $32,000–$48,000 / 6–9 weeks
Premium curbless with multi-head system (multiple shower heads, body sprays, heated floor, possibly steam): $36,000–$48,000 / 7–9 weeks
Pricing assumes Iron Crest's standard scope: full City of Boise plumbing/building permits, professional Schluter Kerdi waterproofing, porcelain or slab porcelain wall tile, frameless glass enclosure, premium thermostatic shower valve and fixtures, and a 5-year workmanship warranty. Contingency budget 8–12% above contract value.
West Boise is not within any City of Boise Historic District. There is no Historic Preservation Commission review. Some West Boise subdivisions have HOA architectural review for exterior modifications, but most are lighter than Harris Ranch HOA review — typically 1–3 weeks rather than 2–4 weeks. Many older West Boise neighborhoods have no HOA at all.
City of Boise standard permits apply for electrical, plumbing, structural, and mechanical work. Permit timelines are typically the fastest in the city for West Boise projects: 2–3 weeks for over-the-counter scopes and 3–4 weeks for full plan review with structural drawings. Production-build documentation is generally well-organized for post-1990 subdivisions.
Modern construction in most West Boise homes (1985 and later) eliminates the asbestos and lead-paint considerations that drive much of the work in North End and Bench projects. Pre-1985 West Boise homes (the original West Boise streets) sometimes contain asbestos in original materials and require lead-safe practices for any pre-1978 paint disturbance. Iron Crest assesses environmental requirements per property during pre-construction.
West Boise lot dimensions are generally generous compared to North End or Bench (typical 60'–90' frontage with 100'–140' depth, often 0.20–0.30 acre). Setback compliance is rarely a constraint. Major additions, ADUs, and detached structures have substantial site flexibility.
Some West Boise subdivisions have specific HOA architectural standards for siding type (Hardie required), roof material (architectural shingles required), exterior color palettes, fence styles, and sometimes ADU restrictions. Iron Crest verifies HOA scope during initial consultation and handles Architectural Review Committee submittal as part of standard project management.
Shower material selection for West Boise primary bathrooms emphasizes modern aesthetic that escapes the 1990s-2000s fiberglass-and-beige-tile signature.
Waterproofing membrane
Schluter Kerdi membrane on all wet areas. We're certified Schluter installers. For curbless designs, Schluter Kerdi-Line linear drains.
Wall tile
Large-format slab porcelain (24×48 or larger, marble-look with veining) or large-format porcelain (12×24, 24×24) is dominant. Stack-pattern subway tile (3×6 or 4×12 in matte white) is the secondary choice. Avoid: small-format colored tile (recreates era), tumbled stone or travertine (also period-tied).
Floor tile and slope
Mosaic tile (1″–2″) for shower floor. White hex mosaic, penny round, or matching small-format porcelain. Floor slope minimum 1/4 inch per foot to drain.
Drain selection
Linear drain (Schluter Kerdi-Line, Infinity Drain) for curbless designs. Standard center drain for traditional curbed showers. Linear drain costs $400–$1,200 above standard.
Glass enclosure
Frameless 3/8″ tempered glass — clean modern aesthetic. Single fixed panel + pivot door, full enclosure, or single fixed panel only depending on layout. Brushed-nickel or polished-chrome hinges and clips.
Fixtures
Thermostatic shower valve. Rain shower head (8″–12″) plus hand-shower on slide bar. Premium-tier: multiple shower heads. Polished chrome or brushed nickel finishes. Avoid: oil-rubbed bronze (era you're escaping), polished brass.
Shower remodels in West Boise homes surface fewer issues than older-home work.
- •Failed waterproofing under existing fiberglass stall. Original 1990s installations sometimes have failed waterproofing causing subfloor damage. Repair: $400–$1,500.
- •Drain location requiring subfloor adjustment. Original fiberglass-stall drain location sometimes doesn't match new shower drain placement. Subfloor cutting and drain rerouting: $400–$1,500.
- •Existing shower valve and rough-in non-compliant with current code. Pre-2000 valve installations often lack anti-scald protection. Existing valve must be replaced. $400–$1,200 above standard.
- •Plumbing supply line capacity for multi-head shower. Premium showers with multiple heads exceed original supply capacity at the valve. Branch-line upgrade: $400–$1,500.
- •Floor structure inadequate for curbless slope. Achieving curbless slope sometimes requires depressing the subfloor in the shower area. Subfloor adjustment: $1,000–$3,500.
- •Heated-floor electrical capacity. Heated-floor systems require dedicated 240V circuit. Panel work: $400–$1,200.
- •Glass enclosure custom-templating challenges. Wall-out-of-plumb conditions occasionally require custom glass templating. $300–$800 above standard glass cost.
- •Exhaust fan capacity for steam shower. Steam-shower additions require dedicated exhaust ventilation. New ducting: $800–$2,000.
- •HOA review for any visible exterior change. Rare for shower-only scope but applicable if new exterior vent penetration is required. $500–$2,000 in design adjustment.

Should I replace my fiberglass shower stall?
Almost universally yes. The original 1990s-2000s West Boise fiberglass shower stall is the most-replaced feature in primary baths in this neighborhood. Reasons: dated aesthetic that signals era, water staining and yellowing accumulate over time, aged seals and gaskets fail, the design fundamentally doesn't match modern spa-tier expectations. Replacement options range from same-footprint walk-in shower ($22,000–$36,000) to oversized walk-in spanning former tub-and-stall zone ($32,000–$48,000).
Should I keep the corner jetted tub or eliminate it?
Depends on household use. If the tub is regularly used or you're planning resale to a buyer pool that values bathtubs, keep it (option A: replace fiberglass stall only). If no one uses the tub and you want maximum shower experience, eliminate it for an oversized walk-in (option B: tub-and-stall replacement). Option A is faster ($22,000–$36,000, 5–7 weeks). Option B is more transformative ($32,000–$48,000, 6–9 weeks).
How long does a West Boise shower remodel take?
5–7 weeks for fiberglass-stall replacement keeping the tub. 6–9 weeks for tub-and-stall replacement with oversized walk-in. 6–8 weeks for aging-in-place curbless. 7–9 weeks for premium with multi-head system.
What waterproofing system do you use?
Schluter Kerdi membrane on all wet areas. We're certified Schluter installers. For curbless designs, Schluter Kerdi-Line linear drains.
Should I do a curbless shower?
For West Boise primary bathrooms, increasingly yes. Curbless is the modern aesthetic standard, eliminates threshold of older curbed designs, provides accessibility benefits. Achieving curbless slope sometimes requires subfloor adjustment ($1,000–$3,500).
What about heated floors?
Excellent feature, particularly extending into the shower area. Schluter Ditra-Heat or NuHeat systems install under porcelain tile. Adds $1,800–$3,500. For West Boise primary baths in $500K+ homes, heated floor is increasingly the standard expectation.
What's the difference vs an older-home shower remodel?
Modern construction means simpler demolition, no environmental remediation in post-1985 homes, faster permits, and predictable mechanical conditions. The complexity is in achieving spa-tier finish on a budget appropriate to the home's price point.
What about glass cleaning in Boise's hard water?
Boise's hard water (12–17 grains per gallon) leaves visible mineral deposits. Application of hydrophobic glass coating (EnduroShield, ShowerGuard) at install time substantially reduces deposit accumulation. Adds $200–$400.
