Shower Remodeling in the Boise Foothills
Curbless walk-in showers, multi-function spa systems, frameless glass enclosures, view-oriented design — Schluter-certified waterproofing for premium Foothills homes.
Shower remodeling in the Boise Foothills follows a specific set of standards driven by the premium tier of typical Foothills homes. Schluter Kerdi sheet membrane waterproofing on every shower (no exceptions, no budget cuts), large curbless walk-in formats with frameless glass enclosures, multi-function shower systems with rain heads and body sprays, premium tile (often natural stone), heated bench and floor, sometimes integrated steam capability, and frequently view-window integration where the primary suite shower wall faces the panoramic view. Iron Crest is Schluter-certified, meaning our Kerdi installations carry the manufacturer's lifetime warranty. We work across the Highlands, Hidden Springs, Foothills East, and the Bogus Basin Road corridor. The premium-tier expectations in Foothills shower work are universal — owners are typically remodeling on $1.2M+ home values and the shower is one of the highlight finishes of the entire property.
Shower strategy in the Foothills depends on era, primary vs. secondary status, and view orientation.
Pre-1970 Foothills (Highlands originals)
Original showers are typically tub-shower combos or small fiberglass-enclosed showers. Often no membrane waterproofing — just felt paper behind tile board, which has likely failed by now. Common scope: full demolition with proper waterproofing retrofit, footprint expansion, conversion to walk-in. EPA RRP applies for any paint disturbance during expansion.
1970s–1980s Foothills
Original primary showers larger — typical 3' × 5' tile-over-cement-board with seat. Original waterproofing is felt paper or thin-set membrane that's now end-of-life. Common scope: full demolition, Schluter Kerdi retrofit, fixture upgrade, glass replacement.
1990s–2000s custom Foothills
Often premium showers from original construction — 4' × 6' or larger walk-in with proper waterproofing for the era. Scope: typically refresh-only with fixture upgrade, glass replacement, sometimes tile refresh. Less common to require full demolition.
2010s–present custom and Hidden Springs
Modern construction with current waterproofing standards. Original showers often premium tier. Scope: typically aesthetic refresh; sometimes upgrade to curbless format and multi-function fixtures.
Foothills shower projects cluster into recognizable shapes shaped by primary/secondary status and ambition.
1. The Premium Primary Spa Shower
Large 4' × 7' or larger walk-in shower in primary suite. Curbless entry with linear drain. Frameless low-iron glass enclosure (sometimes single panel without door for the largest formats). Premium tile throughout — often honed marble or large-format porcelain in marble look. Multi-function shower system: rain head ceiling-mount, handheld on slide bar, 4 body sprays on dedicated valve. Heated bench. Heated floor. Sometimes integrated steam capability.
Target homes: Foothills primary suites at premium tier. Permit: standard plumbing/electrical permits.
2. The Premium Primary with View Integration
Premium primary spa shower with view-window integration. View wall has WUI-compliant tempered window — sometimes floor-to-ceiling glazing with privacy treatment (frosted lower panel or electrochromic glass). Frameless glass enclosure orients toward view. Body sprays and rain head positioned to face away from view (no spray on glass).
Target homes: Foothills primary suites where view wall presents shower opportunity. Permit: standard plumbing/electrical; WUI compliance for new glazing.
3. The Replacement Walk-In
Replacement of dated original primary or secondary shower with curbless walk-in. Schluter Kerdi waterproofing retrofit. Premium tile, frameless glass, multi-function fixtures. Most common Foothills shower scope.
Target homes: Foothills homes with dated original showers. Permit: standard plumbing/electrical permits.
4. The Hidden Springs Shower
Hidden Springs shower renovation within HOA framework. Premium tile (often handmade or designer ceramic for character), frameless glass, premium fixtures matching home aesthetic. ARC review for any visible exterior glazing changes.
Target homes: Hidden Springs primary or secondary baths. Permit: standard plumbing/electrical; HOA ARC where applicable.
5. The Secondary Bath Shower
Secondary bath shower renovation — guest, kids, hall. Premium tier slightly below primary. Walk-in shower with Schluter Kerdi waterproofing, premium tile, frameless glass, mid-premium fixtures. Often combined with full secondary bath renovation.
Target homes: Foothills secondary baths. Permit: standard plumbing/electrical permits.
The Boise Foothills spans roughly two square miles with distinct sub-neighborhoods, each with its own remodeling personality.
Highlands / Castle Hills
The original Foothills neighborhood directly above the North End, climbing the slopes north of Hill Road and Highland Drive. Mix of mid-century ranches, 1970s-80s contemporaries, and significant tear-down-rebuild activity since 2010. Steep streets, dramatic city/valley views to the south, mature pine and juniper landscaping, narrow lots that follow the topography. Homes typically 2,200–4,500 sq ft. Premium price point: $750K–$2.5M.
Hidden Springs
Master-planned village community 8 miles north of downtown Boise off Cartwright Road, developed beginning in 1999 by Hidden Springs Development. Distinct New-Urbanist design with central village, schools, parks, and trails. Hardie-siding craftsman and farmhouse aesthetic, narrower lots than other Foothills areas, deliberate architectural cohesion, active HOA architectural review. Homes typically 2,000–3,800 sq ft on 0.10–0.25 acre lots. $650K–$1.4M.
Quail Hollow / Quail Ridge
Subdivision area off State Street and Pierce Park Lane in the western Foothills. Mostly 1980s and 1990s construction, traditional Foothills aesthetic with shake or composition shingle roofs, exterior wood or stucco. Lots are larger than Highlands (0.25–0.50 acre), grading is gentler, family-focused community character. $550K–$1.1M.
Foothills East / Warm Springs Mesa
The eastern Foothills above Warm Springs Avenue and Table Rock Road, climbing toward the geologic feature of Table Rock. 1960s-70s ranches, 1990s-2000s contemporary infill, and ongoing custom-home construction on irregular lots. Wildfire-prone vegetation surrounds, panoramic city and Owyhee Mountain views, often substantial site grading. $700K–$2.8M+.
Crane Creek / Bogus Basin Road corridor
The remote upper-Foothills areas along Bogus Basin Road and Crane Creek Road, climbing to elevations of 4,500–5,000 feet. Mostly custom homes on multi-acre parcels, sometimes tucked into canyons or perched on ridgelines. Strong wildfire exposure, well/septic infrastructure on the most remote properties, dramatic seasonal road conditions. $850K–$3.5M+.
Foothills shower pricing reflects premium materials, Schluter Kerdi waterproofing, multi-function fixtures, and frameless glass enclosures.

Pricing assumes Iron Crest's standard scope: full City of Boise plumbing and electrical permits, Schluter Kerdi waterproofing system (lifetime warranty), heated floor where applicable, premium tile selection, premium plumbing fixtures, frameless glass enclosure, and a 5-year workmanship warranty plus manufacturer materials warranties.
The Boise Foothills are entirely within the Wildland-Urban Interface (WUI). Idaho WUI building code requirements apply for any new construction, exterior alterations affecting fire-resistance ratings, and significant additions. Required compliance items: Class A roofing assemblies (composition shingle, metal, or rated tile), ignition-resistant siding (fiber cement, stucco, or rated wood), enclosed eaves with ⅛-inch ember-resistant venting, ember-resistant attic vents, defensible-space landscaping. Iron Crest is fluent in WUI compliance and incorporates these requirements into every Foothills project at the design stage.
Foothills construction sites frequently require geotechnical investigation due to slope conditions, expansive clay soils common above 3,200 feet elevation, and seasonal groundwater. Geotechnical reports cost $2,500–$6,500 and may dictate engineered foundation systems including helical piles, deepened spread footings, or stepped foundations. Iron Crest coordinates geotechnical work as part of standard pre-construction for any Foothills project on a slope above 5%.
The City of Boise Hillside Development Ordinance applies to construction on slopes greater than 15%. Plan review is more rigorous, with grading plans, drainage plans, and erosion control plans required as part of building permit submittal. Hillside permit timelines extend to 6–10 weeks. Iron Crest's design team prepares Hillside Development submittals as part of standard project management.
Some Foothills neighborhoods (Hidden Springs, sections of the Highlands, parts of the Foothills East) have HOA architectural review committees. Hidden Springs review is among the most rigorous in Boise — full architectural plans, exterior material samples, and color samples are typically required. ARC review timelines: 2–6 weeks. Iron Crest handles HOA submittal as part of standard project management.
EPA Lead Renovation, Repair and Painting (RRP) Program applies to any work involving paint disturbance in pre-1978 Foothills homes — common in the original Highlands streets and parts of Foothills East. Iron Crest carries RRP certification and follows lead-safe work practices. Asbestos testing required for pre-1980 homes during demolition phase.
Foothills shower material selection emphasizes premium materials, durable waterproofing, and finish details appropriate to property tier.
Waterproofing — Schluter Kerdi sheet membrane (mandatory)
Iron Crest installs Schluter Kerdi sheet membrane on all shower walls, floors, curbs, and curbless transitions. System carries lifetime warranty when installed by certified installer. We are Schluter-certified. Schluter Kerdi-Drain (or linear equivalent) for curbless installations. Schluter-Kerdi-Shower-T or DITRA-Heat for heated assemblies.
Tile — natural stone or designer porcelain
Honed marble (Carrara, Calacatta, Statuario) for premium primary showers; large-format porcelain in marble look for durability with maintenance flexibility; handmade zellige for character primary baths; designer ceramic from Pratt & Larson, Heath Ceramics, or Tabarka Studio for accent or character work. Cost: $28–$120 per square foot installed.
Glass — frameless low-iron premium
Frameless tempered glass with low-iron specification (no green tint, true clear). Standard 3/8-inch thickness; 1/2-inch for largest panels. Hinged door or sliding bypass depending on layout. Sometimes single panel with no door for largest curbless formats. Premium hardware (matte black, brushed brass, polished nickel matching plumbing fixtures). Cost: $2,200–$5,500 installed depending on size and complexity.
Plumbing fixtures — premium multi-function
Premium primary showers: rain head ceiling-mount (Brizo Litze, Kohler Real Rain, Hansgrohe Raindance), handheld on slide bar, 2–4 body sprays on dedicated valve. Pressure-balanced and thermostatic mixing valves for safety. Premium brand suite (Brizo, Kohler, House of Rohl, Hansgrohe). Cost: $4,500–$15,000 for full primary shower fittings.
Heated floor and bench
Schluter Ditra-Heat or NuHeat electric radiant under shower floor and bench tile. Programmable thermostat. Heated bench is a signature Foothills luxury detail — bench top tile feels warm at rest. Cost: $1,200–$3,500.
Steam capability (optional)
Steam generator (Mr. Steam, Kohler) installed in adjacent closet or mechanical space, vented through roof or remote location. Steam-rated tile and waterproofing required. Steam head, controls, and vapor-tight glass enclosure. Cost: $5,500–$11,000 incremental on a base shower project.
Drain — linear or central depending on layout
Linear drain (Schluter-Kerdi-Line, Infinity) along one wall is standard for curbless layouts. Central drain (Schluter-Kerdi-Drain) for traditional curb formats. Premium grate finishes (matte black, polished chrome, brushed brass) matching plumbing fixtures.
Ventilation — high-CFM humidity-sensing
Foothills bathroom moisture loads are significant due to elevation humidity swings. Panasonic WhisperGreen Select humidity-sensing 110+ CFM fan is standard. Sometimes dedicated steam ventilation for steam showers. Cost: $850–$1,800 installed.
Foothills shower remodeling surfaces specific issues during demolition.
- •Pre-1978 lead-based paint on adjacent surfaces. Common in original Highlands homes. Containment for any paint disturbance: $1,500–$4,500.
- •Asbestos in pre-1980 shower wall materials or substrate. Some pre-1980 homes have asbestos cement board substrate. Testing $300–$700. Abatement: $2,500–$6,500.
- •Failed waterproofing or hidden mold from original construction. Original waterproofing in pre-1990 homes often felt-paper-only without membrane. Mold remediation behind original assemblies: $1,500–$8,500 depending on extent.
- •Cast iron drain lines or galvanized supply lines. Common in pre-1970 Highlands. Replacement: $1,800–$5,500 for shower-specific lines. Whole-bath re-pipe sometimes warranted.
- •Inadequate framing or substrate. Original framing sometimes inadequate for new heavy tile loads. Reinforcement: $1,200–$3,500.
- •Outdated electrical (no GFCI, undersized circuit). Steam shower, heated floor, and modern lighting require dedicated 20A GFCI circuits. Electrical upgrade: $1,800–$4,500.
- •Inadequate ventilation. Older Foothills baths often have undersized or no exhaust fan. New high-CFM humidity-sensing fan: $850–$1,800.
- •WUI compliance for new view glazing. View-wall windows in WUI zones must be tempered fire-rated. Cost addition $200–$600 per window.
- •HOA ARC for visible exterior changes (Hidden Springs, parts of Highlands). Mandatory ARC submittal for exterior glazing. Plan revisions: $1,500–$3,500. Timeline addition: 2–4 weeks.

How much does a Foothills shower remodel cost?
$22,000–$35,000 for secondary bath shower; $26,000–$42,000 for Hidden Springs renovation; $28,000–$45,000 for replacement walk-in; $38,000–$58,000 for premium primary spa shower; $42,000–$58,000 for premium with view integration. Premium primary baths in the Foothills typically run $40,000–$50,000 for the shower portion alone.
Will Schluter Kerdi waterproofing be used?
Yes, on every shower without exception. Schluter Kerdi is the industry-standard sheet membrane system. Iron Crest is Schluter-certified, meaning Kerdi installations carry the manufacturer's lifetime warranty. We do not budget-cut waterproofing — proper waterproofing is non-negotiable.
Can the shower be curbless?
Yes — strongly recommended for primary spa showers. Curbless format requires linear drain (or two-way slope to central drain), proper substrate slope, and Kerdi-Shower-T or equivalent waterproofing assembly. Aesthetic benefit is significant; accessibility benefit is also meaningful.
What about the view from a primary shower?
View-wall integration is a signature Foothills primary shower move. Considerations: WUI-compliant tempered glass for view wall window; thermal performance for elevation; privacy via positioning, frosted lower panel, or electrochromic glass; orientation of body sprays away from view glass.
Can I add steam capability?
Yes — Mr. Steam or Kohler steam generators installed in adjacent closet or mechanical space. Requires steam-rated tile and waterproofing, vapor-tight glass enclosure, dedicated electrical circuit, vent location. $5,500–$11,000 incremental on a base shower project.
How long does shower remodel take?
3–5 weeks for secondary bath shower; 4–6 weeks for Hidden Springs or replacement walk-in; 5–7 weeks for premium primary spa shower; 6–9 weeks for premium with view integration. Glass fabrication after tile completion is the typical pacing constraint.
What about heated floors?
Strongly recommended for primary showers. Schluter Ditra-Heat or NuHeat electric radiant installed at the time of tile setting. Programmable thermostat. Heated bench tile is a signature luxury detail in Foothills primary baths. $1,200–$3,500 incremental on a base shower project.
What if hidden mold is discovered behind original assemblies?
Common discovery in pre-1990 Foothills homes where original waterproofing has failed. Iron Crest assesses extent at demolition phase and provides remediation cost addition. Range $1,500–$8,500. We do not install new waterproofing over hidden mold — we abate and rebuild substrate properly.
