Bathroom Remodeling in the Boise Foothills
Spa-grade primary baths, view-window integration, walk-in showers, custom vanities, hillside engineering — premium Foothills bathroom renovation.
Bathroom remodeling in the Boise Foothills follows the same fundamental rules as Foothills kitchen work — view orientation matters, hillside structural conditions affect any wall removal, WUI compliance applies to new exterior openings, and finish tier expectation is premium. The specific dynamic for bathrooms: primary suites on Foothills homes are almost always positioned to capture the best views in the home, which means primary bath renovations often include view-window expansion at the freestanding tub or shower wall. This is a signature Foothills move — soaking tub or walk-in shower facing the panoramic glazing — and getting it right requires WUI-compliant glazing, careful framing for tub or shower wall, privacy considerations (the panoramic view also means visibility from below grade if not designed carefully), and integrated lighting design. Iron Crest has remodeled bathrooms across the Highlands, Hidden Springs, Foothills East, and the upper Bogus Basin Road properties. Our scope expectations match the property tier: custom cabinetry, premium fixtures (Kohler Memoirs, House of Rohl, Brizo Litze), natural stone surfaces, integrated lighting, sometimes integrated TVs and audio, and Schluter Kerdi waterproofing on every shower. Foothills owners typically remodel primary baths to spa standard and secondary baths to a slightly lower but still premium tier.
Bathroom strategy in the Foothills depends heavily on era, primary vs. secondary status, and view orientation.
Pre-1970 Foothills (Highlands originals)
Original primary bathrooms are small (5' × 8' typical) with limited fixtures, no walk-in shower, sometimes only a tub-shower combo. Secondary baths similarly modest. Common scope: footprint expansion (often into adjacent closet or bedroom), full layout reconfiguration, view-window integration. EPA RRP applies for paint disturbance.
1970s–1980s Foothills
Primary bathrooms expanded — typical 8' × 12' to 10' × 14' with separate tub and shower, double vanity. Original finishes are dated (oak vanities, beige tile, fiberglass tubs). Common scope: full renovation with finish upgrades, often Schluter waterproofing retrofit (original showers were rarely properly waterproofed). View-window expansion where applicable.
1990s–2000s custom Foothills construction
Custom-built primary baths often premium tier from original construction (granite vanities, jetted tubs, custom showers). Scope: typically refreshes with finish updates and fixture replacement. Sometimes layout changes to add walk-in shower or freestanding tub.
2010s–present custom and Hidden Springs
Modern construction often already has premium bathroom finishes. Hidden Springs original bathrooms are well-built within HOA framework. Scope: typically aesthetic refreshes; sometimes upgrades to freestanding tubs and curbless showers within HOA guidelines.
Foothills bathroom renovations cluster into recognizable project shapes shaped by primary/secondary status and view orientation.
1. The Primary Spa — view-oriented owner suite bath
Full primary bath renovation oriented around panoramic view. Typical features: freestanding soaking tub at view window, large curbless walk-in shower with rain head and body sprays, double vanity with custom cabinetry, water closet in private compartment, heated floor, integrated lighting, sometimes integrated TV in vanity mirror or steam capability in shower.
Target homes: Foothills primary suites with view potential. Permit: full plumbing, electrical, mechanical permits; WUI compliance for new exterior glazing.
2. The Primary Refresh — premium finish update without layout change
Existing primary bath layout works but finishes need updating. Cabinetry replacement, counter and tile upgrade, fixture replacement, lighting upgrade, sometimes shower glass and door upgrade.
Target homes: Foothills primary baths with sound layout but dated finishes. Permit: standard plumbing/electrical permits as needed.
3. The Footprint Expansion — adding spa space
Existing primary bath is too small for spa-tier renovation; project expands footprint into adjacent closet, bedroom, or hallway space. Often involves wall removal requiring structural engineering.
Target homes: Pre-1980 Foothills homes with undersized primary baths. Permit: full plan review with structural drawings if walls move.
4. The Hidden Springs Renovation — within ARC framework
Hidden Springs HOA-aware primary bath. Cabinetry refresh, premium counter and tile, freestanding tub or curbless shower, refreshed fixtures. Any visible exterior modifications require ARC review.
Target homes: Hidden Springs homes with original primary baths. Permit: standard plumbing/electrical; HOA ARC submittal where exterior changes.
5. The Secondary Bath — guest, kids, hall, powder
Secondary bathroom renovation at finish tier slightly below primary. Updated vanity, premium counter and tile, fixture replacement, lighting, often shower-tub or walk-in shower upgrade.
Target homes: Foothills homes with secondary baths needing update. Permit: standard plumbing/electrical permits as needed.
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 bathroom pricing reflects premium finish tier expectations and additional WUI/structural costs for projects involving exterior or load-bearing modifications.
Boise Foothills bathroom remodeling ranges
Secondary bath refresh (vanity, counter, tile, fixtures, lighting at premium finish tier): $48,000–$88,000 / 6–10 weeks
Primary refresh (finish updates without layout change; premium materials throughout): $58,000–$110,000 / 8–12 weeks
Hidden Springs renovation (HOA-compliant primary or secondary bath with full premium finish update): $58,000–$115,000 / 10–14 weeks
Footprint expansion primary (wall removal and footprint growth, full premium finish): $85,000–$155,000 / 12–16 weeks
Primary spa with view (view-oriented design, freestanding tub at view window, custom shower, full integrations): $95,000–$185,000 / 12–18 weeks
Pricing assumes Iron Crest's standard scope: full City of Boise permit, Schluter Kerdi waterproofing on all wet areas, WUI-compliant glazing for any new exterior windows, premium plumbing fixtures, hillside structural engineering where wall removal involved, HOA ARC submittal where applicable, and a 5-year workmanship warranty + 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 bathroom material selection emphasizes spa-grade materials, durable waterproofing, and finish details appropriate to the property tier.
Waterproofing — Schluter Kerdi system on every shower
Iron Crest installs Schluter Kerdi sheet membrane on all shower walls, floors, and curbs (or curbless transitions). System carries lifetime warranty when installed by certified installer. We are Schluter-certified. No exceptions for budget projects — proper waterproofing is non-negotiable in the Foothills where seasonal humidity swings stress assemblies.
Tile — natural stone, large-format porcelain, or designer ceramic
Honed marble (Carrara, Calacatta) for premium primary baths; large-format porcelain in marble look for durability with lower maintenance; handmade zellige for accent walls; Pratt & Larson designer tile for character moments. Cost: $18–$95 per square foot installed depending on material and complexity.
Vanities — custom cabinetry with integrated pulls
Custom local-fabricated vanities are standard for Foothills primary baths. Painted or stained cabinetry with integrated pulls or premium hardware. Quartzite, marble, or premium quartz tops with undermount sinks. Cost: $1,200–$2,800 per linear foot for premium custom.
Plumbing fixtures — premium brand suite
Kohler Memoirs Stately or Artifacts series, House of Rohl Perrin & Rowe, Brizo Litze, Hansgrohe Axor for premium tier. Toto Neorest or Kohler Veil intelligent toilets. Freestanding tubs from Victoria + Albert, Native Trails, or Kohler Iron Works. Cost: $8,500–$28,000 for full primary bath fixture package.
Shower systems — multi-function with body sprays
Premium primary showers include rain head (12-inch or larger ceiling-mount), handheld on slide bar, and 2–4 body sprays on dedicated valve. Steam capability optional ($5,500–$11,000 incremental). Custom glass enclosure (frameless, low-iron glass) standard. Cost: $9,500–$22,000 for full premium shower fittings and glass.
Heated floors — radiant electric or hydronic
Radiant electric (Schluter Ditra-Heat or NuHeat) is standard for primary bath floors. Hydronic radiant where home has boiler. Programmable thermostat. Cost: $1,800–$4,500 for primary bath; $1,200–$2,800 for secondary.
Lighting — layered designer
Layered lighting essential in Foothills baths because the dramatic views often render the room dark in evening hours. Recessed downlights for general; designer sconces (Visual Comfort, Hudson Valley, Cedar & Moss) flanking vanity mirrors at face height; sometimes pendant over freestanding tub; integrated mirror lighting for makeup application. All on dimmer-controlled circuits. Cost: $3,500–$8,500 for full primary bath lighting.
WUI-compliant glazing for view windows
View windows in Foothills bathrooms must be WUI-compliant — tempered dual-pane with fire-rated certification. Triple-pane high-performance (Marvin, Pella, Andersen) for thermal performance. Privacy considerations: frosted lower panel, electrochromic glass, or careful elevation positioning. Cost: $1,500–$4,500 per window.
Foothills bathroom renovations surface specific issues tied to era, hillside conditions, and original construction quality.
- •Pre-1978 lead-based paint disturbance. Common in original Highlands homes (pre-1978) and parts of Foothills East. EPA RRP-certified containment required. Cost addition: $2,500–$7,500 for bathroom scope.
- •Asbestos in pre-1980 sheet flooring, mastic, popcorn ceilings, or pipe insulation. Common in pre-1980 Highlands homes. Testing: $300–$700 per sample. Abatement: $3,500–$11,500 depending on quantity.
- •Failed waterproofing or hidden mold from prior shower assemblies. Original showers in pre-1990 homes often have failed waterproofing — felt-paper-only with no membrane system. Mold remediation: $1,500–$8,500 depending on extent. Iron Crest tests assumes failure and budgets for remediation.
- •Cast iron drain lines or galvanized supply lines reaching end-of-life. Common in pre-1970 Highlands homes. Drain replacement: $2,500–$6,500. Supply line replacement: $1,800–$5,500. Sometimes whole-home re-pipe is logical concurrent project.
- •Outdated electrical including no GFCI, undersized circuits, or knob-and-tube. Bathrooms must have GFCI outlets and dedicated 20A circuit per code. Older Foothills homes often need full bathroom rewire. Cost: $2,500–$5,500.
- •Inadequate exhaust ventilation. Many older Foothills bathrooms have no fan or undersized fan creating moisture problems exacerbated by elevation. New high-CFM humidity-sensing fan (Panasonic WhisperGreen Select): $850–$1,800 install.
- •Hillside structural lateral analysis if walls move. Walls in hillside Foothills homes may carry lateral load. Engineering for wall removal: $3,500–$8,500 versus standard $1,500–$3,500.
- •WUI compliance for new exterior glazing. New windows in WUI zones require ignition-resistant assemblies. Cost addition: $200–$600 per window.
- •HOA Architectural Review for visible exterior changes (Hidden Springs, parts of Highlands). Mandatory ARC submittal for any exterior change. Plan revisions per ARC feedback: $1,500–$3,500. Timeline addition: 2–6 weeks.

How much does a Foothills primary bathroom cost?
$58,000–$110,000 for refresh; $85,000–$155,000 for footprint expansion; $95,000–$185,000 for a view-oriented spa primary with freestanding tub at panoramic window, custom shower, premium fixtures throughout. Secondary baths run $48,000–$88,000 for premium-tier renovation.
How long does a Foothills bathroom renovation take?
6–10 weeks for secondary bath; 8–12 weeks for primary refresh; 10–14 weeks for Hidden Springs renovation; 12–16 weeks for footprint expansion; 12–18 weeks for view-oriented spa primary. Custom vanity lead time (8–14 weeks) and freestanding tub lead time (4–10 weeks) are typical pacing constraints.
Will Schluter Kerdi waterproofing be used?
Yes, on every shower without exception. Schluter Kerdi is the industry-standard sheet membrane system for shower waterproofing. Iron Crest is Schluter-certified, meaning Kerdi installations carry the manufacturer's lifetime warranty. We don't budget-cut waterproofing — proper waterproofing is non-negotiable in any Foothills bath.
Can the freestanding tub be at the view window?
Yes — this is a signature Foothills primary bath move. Considerations: WUI-compliant tempered glass for the window; thermal performance for elevation; privacy via positioning, frosted lower panel, or electrochromic glass; structural framing for tub weight (a filled cast iron tub can weigh 1,200+ lbs); proper drain plumbing.
Do you handle Hidden Springs HOA review?
Yes. Hidden Springs ARC review for any visible exterior modification (typically affecting bathrooms only when window changes are involved). We prepare full architectural plans, exterior material samples, and color samples per ARC requirements.
What WUI requirements apply to bathroom renovation?
If the project includes any new or replacement exterior glazing (windows, skylights, glass blocks), those assemblies must be WUI-compliant — fire-rated tempered glass, ignition-resistant frames. Iron Crest builds WUI requirements into every Foothills design.
What about heated floors at Foothills elevation?
Strongly recommended. Foothills bathrooms experience significant temperature swing — radiant heated floors transform daily comfort. Schluter Ditra-Heat or NuHeat electric systems install at the time of tile setting and are programmable. Hydronic radiant where home has boiler. $1,800–$4,500 for primary; $1,200–$2,800 for secondary.
What if knob-and-tube wiring is discovered during demolition?
Common in pre-1970 Highlands homes. Iron Crest does not install new bath finish over knob-and-tube — it's a fire safety hazard, especially in WUI environments. We rewire the bathroom and recommend full home rewire if discovered extensively. Cost addition: $2,500–$5,500 for bathroom-only.
