Bathroom Remodeling in the East End / Warm Springs
Period-appropriate bathroom renovations for 1900–1925 East End bungalows and Warm Springs Craftsman homes — primary suite additions, footprint expansions, lead-safe practices.
Quick answer
$45,000–$95,000 for original restoration; $55,000–$110,000 for period-appropriate renovation; $78,000–$145,000 for footprint expansion; $110,000–$165,000 for Warm Springs premium spa primary; $135,000–$215,000 for primary suite addition.
Bathroom remodeling in the East End and Warm Springs Avenue addresses a specific scope: 1900–1925 homes that originally had one or two small bathrooms with claw-foot tubs and pedestal sinks — plus the universal challenges of plaster-and-lath walls, original cast iron drains, lead paint, and sometimes asbestos. Modern East End bathroom work usually means primary suite additions on top of original homes, footprint expansions into adjacent closets or hallways, complete renovation of secondary bathrooms while preserving period character, and integration with geothermal heating systems where applicable. Iron Crest's East End bathroom work emphasizes period-appropriate fixture and finish selection (Kohler Memoirs Stately, House of Rohl Perrin & Rowe, period-style tile patterns including hex mosaic and subway tile), Schluter Kerdi waterproofing on every shower, EPA RRP lead-safe practices, plaster restoration where walls remain, careful integration of modern function with original architectural language, and HPC review where exterior changes are involved.
Bathroom strategy in the East End depends heavily on era and degree of architectural significance.
Pre-1900 Warm Springs Avenue mansions
Queen Anne and Colonial Revival mansions often had multiple original bathrooms (1–2 family bathrooms plus servants' bath) on multiple floors. Original fixtures sometimes claw-foot tubs and pedestal sinks worth restoring. Modern scope: primary suite addition or comprehensive renovation of existing bathrooms with period-appropriate finishes.
1900–1925 Craftsman estates and bungalows
Original bathrooms were small, with claw-foot or built-in cast iron tub, pedestal sink, sometimes high-tank toilet. Modern scope: footprint expansion into adjacent closet or hallway, full renovation, period-appropriate replacement.
1925–1940 transitional homes
Original bathrooms are more spacious, with built-in tub-shower combos common, pastel tile palettes (pink, mint, blue, yellow). Sometimes restoration of original tile is appropriate where character is intact; sometimes replacement is justified.
Post-1940 East End infill
Smaller infill homes from 1945–1980 within East End boundaries. Less period-significant; modern renovation appropriate. EPA RRP applies for pre-1978 construction.
East End bathroom renovations cluster into recognizable shapes by era and ambition.
1. The Primary Suite Addition
New primary suite added to existing East End home — typically rear addition. Includes primary bedroom, walk-in closet, and primary bath with walk-in shower, freestanding tub (period-appropriate), double vanity. Architectural massing and exterior details must respect original home and HPC requirements.
Target homes: East End homes lacking primary suite. Permit: full plan review with structural; HPC review for exterior addition.
2. The Footprint Expansion
Existing primary or secondary bath too small; expansion into adjacent closet, hallway, or bedroom. Often involves wall removal requiring structural work and plaster restoration where walls remain.
Target homes: Pre-1925 East End homes with undersized original bathrooms. Permit: full plan review with structural drawings.
3. The Period-Appropriate Renovation
Existing bathroom layout works but finishes need updating. Period-appropriate fixtures (Kohler Memoirs, House of Rohl), classic tile patterns (hex mosaic, subway, basket weave), modern function with classic aesthetic.
Target homes: East End homes wanting period-respectful finish update.
4. The Original Restoration
Original bathroom retains significant period character (claw-foot tub, original tile, pedestal sink) worth preserving. Modern remodel works around the period elements — restoring original fixtures, replacing only what's beyond service, modernizing electrical and plumbing while preserving aesthetic.
Target homes: East End homes with original bathrooms intact.
5. The Warm Springs Spa Primary
Premium primary bath on Warm Springs Avenue mansion. Spa-grade scope with double vanity, walk-in shower with multi-function fixtures, freestanding period-appropriate tub (cast iron Victoria + Albert or Kohler Iron Works), heated floor (geothermal-integrated where applicable), period-appropriate fixtures throughout.
Target homes: Warm Springs Avenue homes at premium tier. Permit: standard plumbing/electrical permits.
The East End / Warm Springs is made up of distinct sub-neighborhoods, each with its own remodeling personality.
Warm Springs Avenue Historic District
The premier residential corridor along Warm Springs Avenue. The City of Boise records it as listed on the National Register of Historic Places in 1979 and designated a local historic district by Boise City in 1996, with a period of significance of 1910–1940 and predominant styles of Queen Anne, Colonial Revival, Mission Revival, Tudor Revival and Bungalow. The City describes the lots on the south side of the avenue as more than an acre, with the north-side parcels more uniform and served by rear alleys. Many homes use geothermal heating drawn from the underlying hot-water aquifer; the City of Boise describes its system as "one of the oldest and largest geothermal systems in the world".
East End — Bungalow Belt
The dense bungalow neighborhoods between Broadway Avenue and the Foothills. The City of Boise designated the East End Historic District a local historic district in 2004, describes it as a thirty-nine-block residential neighbourhood developed through subdivisions beginning in 1890, gives it a period of significance of the 1910s–1940s, and records Craftsman Bungalow as its largest single style at 29 percent, alongside Queen Anne, American Foursquare, Mission Revival and Spanish Eclectic. The City records the district's parcels as small — typically 25 feet wide and 122 feet deep, with corner lots 30 feet wide. Local designation means Historic Preservation Commission review applies to exterior work.
Reserve Street area
The corridor along Reserve Street north of the river. A mix of older homes, post-war ranches and later infill. Much of this area sits outside a designated historic district — confirm your specific address with Boise Planning & Development Services.
East Boise — Table Rock transitional
The transitional zone between the East End and the Foothills, climbing from Warm Springs Avenue up toward Table Rock. Some properties have geothermal heat extending from the Warm Springs district.
Reserve / Eastland infill streets
Smaller streets and infill developments throughout the broader East End. Lots vary widely, and parts of this area sit outside the formal historic district boundaries — confirm your specific address with Boise Planning & Development Services.
Most Boise bathroom remodel projects run $12,000 to $95,000 — the band published on our Boise bathroom remodel page. The ranges below run higher than that band because of the East End's pre-1928 housing stock, Historic Preservation Commission review on any change visible from the street, and EPA RRP lead-safe practice on effectively every address. East End bathroom pricing reflects period-appropriate fixture and finish tier, plaster-and-lath complexity, lead-safe protocols, and HPC review where applicable.
East End / Warm Springs bathroom remodeling ranges
Original restoration (Preserve original fixtures and modernize selectively): $45,000–$95,000 / 8–12 weeks end to end
Period-appropriate renovation (Period-appropriate fixtures and finishes without layout change): $55,000–$110,000 / 8–12 weeks end to end
Footprint expansion (Wall removal and footprint growth into adjacent space): $78,000–$145,000 / 12–18 weeks end to end
Warm Springs spa primary (Premium primary bath with spa-grade scope): $110,000–$165,000 / 12–18 weeks end to end
Primary suite addition (New primary suite addition with primary bath): $135,000–$215,000 / 9–14 months end to end
Pricing assumes Iron Crest's standard scope: full City of Boise permit, EPA RRP lead-safe practices throughout, asbestos testing during demolition, plaster-and-lath demolition and repair where applicable, Schluter Kerdi waterproofing on all wet areas, geothermal heat coordination where applicable, period-appropriate fixtures and finishes, HPC submittal where applicable, and a 3-year workmanship warranty + manufacturer materials warranties.
The City of Boise designates ten historic districts. Two of them cover this area: the Warm Springs Avenue Historic District (National Register 1979, local designation 1996) and the East End Historic District (local designation 2004). Both are locally designated, so Historic Preservation Commission review applies to visible exterior changes in both — a National Register listing alone would not create local design review, but Warm Springs Avenue carries the local designation as well. Confirm the current boundaries and review requirements with Boise Planning & Development Services before an exterior scope is priced.
HPC review is required for any exterior modification visible from the public right-of-way — siding type and colour, window replacement, roof material, porch modifications, additions, accessory structures, fencing. Interior work is exempt from HPC review. Iron Crest handles HPC submittals as part of standard project management. HPC review happens at the Commission's monthly meeting and can add several weeks; confirm current timelines with Boise PDS. Building Division: (208) 608-7070. Planning & Zoning: (208) 608-7100.
Note that the 20 percent federal historic rehabilitation tax credit applies only to income-producing property under National Park Service rules. It does not reach an owner-occupied house, whatever district the house sits in.
EPA Lead Renovation, Repair and Painting (RRP) Program applies to virtually every East End project given the pre-1978 construction. Iron Crest follows EPA RRP lead-safe work practices including HEPA containment, wet-paste paint scraping, lead-safe disposal, and final clearance testing where required.
Many East End and Warm Springs Avenue homes use geothermal heating from the City of Boise Geothermal District — heat exchanged from naturally hot underground water. Geothermal heat affects HVAC scope: existing radiant baseboards, hydronic radiators, or fan-coil units must be properly integrated or replaced with appropriate systems. Iron Crest has experience with the Boise geothermal system specifically.
Asbestos testing is recommended for pre-1980 demolition work — common locations include sheet flooring, mastic, popcorn ceilings, pipe insulation, vinyl asbestos tile, and sometimes roofing felt or building paper. Older East End homes often have plaster-and-lath walls with horsehair binder rather than later drywall — different demolition and repair practices apply.
East End bathroom materials must complement the original architectural language while delivering modern function and durable waterproofing.
Waterproofing — Schluter Kerdi system on every shower
Iron Crest installs Schluter Kerdi sheet membrane on all shower walls, floors, and curbs. Lifetime warranty when installed to Schluter's published specifications.
Tile — period-appropriate patterns
Hex mosaic floor tile (1-inch or 2-inch) in white, cream, or black is period-appropriate. Subway tile (3×6 or 4×8 inch) for shower and tub surrounds. Basket weave or octagon-and-dot for elevated period detail. Handmade ceramic from Pratt & Larson, Heath, or Tabarka for character. Cost: $18–$95 per square foot installed.
Vanities — period-style or custom matching
Pedestal sinks in primary spaces preserve period aesthetic. Custom vanities in painted Shaker or inset cabinetry for primary baths needing storage. Stone counters (marble, quartzite) on built vanities. Cost: $1,200–$2,800 per linear foot for premium custom; $1,500–$5,500 for premium pedestal.
Plumbing fixtures — period-appropriate premium suite
Kohler Memoirs Stately or Artifacts series, House of Rohl Perrin & Rowe Edwardian, Brizo Charlotte, Newport Brass — all evoke period without being literal reproductions. Toto Drake or Promenade toilets in classic styling. Freestanding tubs from Kohler Iron Works (cast iron) or Victoria + Albert (composite). Cost: $8,500–$28,000 for full bath fixture package.
Hardware — unlacquered brass or polished nickel
Unlacquered brass (Rocky Mountain Hardware, Rejuvenation), polished nickel, or chrome are period-appropriate. Avoid contemporary matte black or contemporary brushed bronze that fights home aesthetic.
Lighting — period-style sconces and fixtures
Schoolhouse Electric, Rejuvenation, Visual Comfort period-style sconces flanking vanity. Schoolhouse-style flush mount or single-bulb pendant for primary illumination. Glass shade pendants over freestanding tub. All on dimmer-controlled circuits. Cost: $3,500–$8,500 for full bath lighting.
Heated floors — radiant integration with geothermal
Schluter Ditra-Heat or NuHeat electric radiant for typical East End baths. Where home has geothermal heating, sometimes hydronic in-floor heating integrated with geothermal system instead of electric. Cost: $1,800–$4,500 for primary; $1,200–$2,800 for secondary.
Plaster restoration around remaining walls
Where walls remain in renovation, plaster patching with proper bonding agent and finish coat. Sometimes integration of new tile around old plaster-and-lath. Skim-coat blending for transitions. Cost: $35–$85 per square foot of plaster repair.
East End bathroom renovations reliably surface specific issues during demolition.

How much does an East End bathroom remodel cost?
$45,000–$95,000 for original restoration; $55,000–$110,000 for period-appropriate renovation; $78,000–$145,000 for footprint expansion; $110,000–$165,000 for Warm Springs premium spa primary; $135,000–$215,000 for primary suite addition.
Will my bathroom remodel need HPC review?
If your home is in the East End Historic District or the Warm Springs Avenue Historic District AND the project includes any exterior change visible from public right-of-way (new exterior windows, new exterior doors, additions), then yes. Pure interior renovations typically don't trigger HPC. Iron Crest verifies HPC scope at consultation.
Can I keep the original claw-foot tub?
Often yes — original cast iron claw-foot tubs are durable and can be restored beautifully. Refinishing inside surface ($800–$1,500), exterior cleaning and refinishing if painted, new claw feet hardware if needed, new freestanding tub filler. Result is a centerpiece period-correct primary bath element.
What about original tile?
Original 1920s-30s tile in pastel colors (pink, mint, blue, yellow) sometimes has character worth preserving — but condition determines feasibility. Cracked, water-damaged, or partially-removed tile generally isn't worth saving. Intact original tile sometimes inspires complementary new tile work.
How does geothermal heat affect bathroom renovation?
Where home has geothermal, primary baths can use hydronic in-floor heating integrated with the geothermal system rather than electric radiant. More efficient operation. Iron Crest coordinates with City of Boise geothermal system.
What waterproofing is used?
Schluter Kerdi sheet membrane on every shower. Lifetime warranty when installed to Schluter's published specifications.
How long does an East End bathroom remodel take?
8–12 weeks for original restoration or period-appropriate renovation; 12–18 weeks for footprint expansion or Warm Springs spa primary; 9–14 months for primary suite addition. HPC review adds time where applicable — the Commission meets monthly, so confirm the current review timeline with Boise PDS.
What if asbestos is found in original sheet flooring?
Common in East End pre-1980 homes. Testing first ($300–$700 per sample), then abatement before demolition can proceed safely. Cost: $3,500–$11,500 depending on scope. Iron Crest budgets contingency for asbestos discovery in pre-1980 East End projects.
