Shower Remodeling on 30th Street, Sunset Park & the Whitewater Corridor
Walk-in conversions in 1925 bungalows two blocks off 30th, post-war minimums near Veterans Park, and townhomes overlooking the Whitewater Park — built around Schluter Kerdi waterproofing and pre-1940 plaster-and-lath protocols.
Shower work in Sunset is shaped by three things you don't get in other Boise neighborhoods at the same intensity: the universal cast-iron tub-shower combo on every original 1925–1965 floor plan, the plaster-and-lath wall systems still in place behind tile-board on the bungalows north of West State Street, and a value curve that's pulled the corridor from $325K (2018) to $475K–$985K (2026) — which means the budget math now supports a tier of finish that didn't pencil here a few years ago. The dominant scope is converting an original Crane or American-Standard cast iron tub-shower to a walk-in with frameless glass. We Schluter-Kerdi every shower without exception (lifetime manufacturer warranty), break-out the cast iron in place when we can't carry it through a 26"-wide bungalow door, and in pre-1940 originals near 32nd and Boone we run a plaster-and-lath demolition protocol that drywall-only crews aren't equipped for. EPA RRP applies to every Sunset address — the entire neighborhood predates 1978 paint regulation. Where pricing is calibrated: the corridor's gentrification curve makes Carrara-look porcelain, House of Rohl chrome, and curbless linear-drain layouts a defensible spend on resale, where the same package would over-improve a comparable house in a flat market.
Sunset's housing stock breaks into four distinct shower-relevant eras, each with its own demolition rules and finish ceiling.
1920s–1939 original Sunset Craftsman bungalows (the streets between 27th and 33rd north of State)
5'×7' or 5'×8' primary baths with a 60-inch Crane or Standard cast iron tub, integrated soap dishes pressed into the cast wall, hex floor mosaic, and 4×4 wainscot tile to chair-rail height. Plaster-and-lath wall system. Built-in shower over tub with original chrome ring or curtain rod added later. Failed pan, failed mortar, no real waterproofing. Demolition is plaster-and-lath protocol, not drywall — different cuts, different debris weight, different dust profile. Modern scope: full tub demolition (typically break-out), period-appropriate walk-in with hex mosaic floor and 3×6 subway, classic chrome trim. Some owners ask us to salvage and re-mount the original integrated soap dishes.
1940s–1959 post-war minimum-traditional and ranch (Sunset Park, Veterans Park, 28th–34th south of State)
5'×7' bath with a 60-inch built-in cast iron tub-shower. Pastel tile (pink, mint, sea-foam) frequently survives original — Sunset has more period-correct surviving tile than Boise Bench because earlier waves of remodeling skipped it. Sometimes felt-paper-only behind the tile board. Walls usually drywall + plaster-skim, simpler demolition than the bungalows. Galvanized supply still in service in many. Modern scope: full demolition, walk-in with linear drain, large-format porcelain.
1960–1975 ranch and split-entry (Lower Bench transition south of Veterans Memorial Parkway)
Slightly larger 5'×9' baths, sometimes with a separate fiberglass shower stall in addition to the tub. Drywall throughout, copper supply common, ABS or cast iron drains. Modern scope: walk-in conversion or upgrade of the existing stall to a Schluter-tiled walk-in. Lower discovery work than bungalow streets.
2010–2024 30th Street infill townhomes (Whitewater Park / Esther Simplot perimeter)
New construction shower stalls — typically a 36×60 fiberglass insert that owners now want upgraded to tile. Cement board behind, modern PEX supply, no asbestos or lead concerns. Conversion is straightforward Schluter retrofit. Permitting is sometimes complicated by the 30th Street transit-oriented development overlay if scope touches the structure.
Five recurring project shapes account for nearly every Sunset shower we quote. The cost spread tracks the era, lot value, and whether the home is staying with the owner or being prepped for sale into the corridor's appreciation curve.
1. The 1925 Bungalow Walk-In (Period-Appropriate)
Replacement of the original Crane cast iron tub-shower with a walk-in tiled to bungalow vocabulary: 1-inch hex mosaic floor in white or matte black, 3×6 subway up to chair-rail with pencil-liner cap, classic chrome thermostatic valve, frameless 3/8" glass. Often pairs with restoring or re-mounting the original integrated soap dishes. We run the plaster-and-lath demolition protocol throughout.
Target homes: Pre-1940 original Sunset bungalows on 27th–33rd north of State Street, between 1,200 and 1,800 sq ft. Permit: standard plumbing/electrical, no historic-district review (Sunset is not within a Boise Historic District).
2. The Cast-Iron Tub Walk-In Conversion
Conversion of an original 1945–1965 built-in cast iron tub-shower to a walk-in with linear drain, large-format porcelain (24×48 marble-look), and frameless glass. Kerdi-Shower-T pre-slope. Galvanized-to-PEX supply re-pipe at the wet wall is typical. Most common Sunset shower scope by volume.
Target homes: 1945–1970 Sunset Park, Veterans Park, and Lower Bench homes with the original 5'×7' tub-bath. Permit: standard plumbing/electrical.
3. The Resale-Aware Gentrification Shower (30th Street Corridor)
Walk-in shower priced and specified for owners selling into the corridor's $750K–$985K resale band. Designer porcelain (Florim, Atlas Concorde), Brizo or House of Rohl polished chrome, frameless low-iron glass, recessed niche lit with under-counter LED strip. The aesthetic is current 2026 magazine work, not period — assumes the buyer is a professional couple from out-of-state who liked the corridor walking distance to Push & Pour and the Greenbelt.
Target homes: Sunset homes within walking distance of the 30th Street commercial strip or Whitewater Park, prepped for sale.
4. The Premium Primary Walk-In (Curbless, Heated)
4'×6' or larger curbless walk-in in a primary suite. Linear trench drain, Schluter-Kerdi-Shower-T pre-slope, low-iron glass enclosure with point-supported hinges, integrated bench heated by Schluter Ditra-Heat, multi-function valve with rain head and handheld. Standard configuration for Sunset Park primary additions and the higher-end 32nd Street remodels.
Target homes: Sunset primary suites, especially in homes that have already had a footprint expansion. Lots near 32nd and Esther Simplot tend to support this tier.
5. The Secondary / Hall Bath Shower
Smaller Schluter-tiled walk-in for a secondary or hall bath. Mid-premium fixtures (Moen Genta, Kohler Pinstripe), 12×24 porcelain, framed or semi-frameless glass. Common when the primary is staying as-is and a guest bath is being modernized.
Target homes: Sunset secondary baths in homes where the primary has already been done or is staying.
The Sunset / 30th Street spans roughly two square miles with distinct sub-neighborhoods, each with its own remodeling personality.
30th Street commercial / Whitewater Park
The recently revitalized commercial-residential corridor along 30th Street between West State Street and the Boise River. Anchored by the Boise Whitewater Park (kayaking and surfing wave), Esther Simplot Park, the Greenbelt, and the 30th Street commercial district (Push & Pour, Local Cellular, Steelhead, breweries). Mix of original 1920s-40s bungalows undergoing gentrification, mid-century infill, and new 2010s-2020s townhomes and small apartment buildings. Walkable urban character. Home values $475K-$985K (single-family) with strong appreciation curve.
Sunset Park / West State Street
The neighborhood centered on Sunset Park along West State Street and surrounding residential streets. Predominantly 1925-1955 single-family homes (1,200-1,800 sq ft) on 50' × 110' to 60' × 130' lots. Quieter than 30th Street corridor, family-focused community character with mature street trees. Home values $475K-$785K.
Veterans Park
The neighborhood surrounding Veterans Memorial Park along Veterans Memorial Parkway, west of Sunset Park. Mix of 1940s-60s post-war housing and 1970s-80s infill. Lots typically 60' × 120'. Strong family-focused community with park access and Greenbelt proximity. Home values $475K-$785K.
Lower Bench transition (south side)
The southern edge of Sunset where the neighborhood transitions toward the geological Boise Bench. Mix of 1940s-60s post-war ranches and 1970s-80s splits. Slightly elevated terrain compared to the Whitewater Park flats. Home values $425K-$685K.
Original Sunset bungalow streets
The earliest Sunset streets, predating the 1940s-50s post-war wave. 1920s-30s Craftsman bungalows and minor revival styles, sometimes with substantial original architectural character. Pre-1940 construction occasional EPA RRP and asbestos considerations. Lots typically 50' × 110'. Home values $485K-$725K.
32nd Street / Esther Simplot Park area
The neighborhoods immediately north of Esther Simplot Park along 32nd Street and surrounding residential streets. Mix of 1930s-50s bungalows and ranches with significant recent investment. Walking distance to park amenities, Whitewater Park, downtown bridges. Home values $525K-$925K.
Pricing reflects the corridor's value curve, the universal pre-1978 EPA RRP overhead, and the real cost of plaster-and-lath demolition on pre-1940 streets.
Sunset / 30th Street shower remodeling ranges
Secondary / hall bath (Schluter-tiled walk-in, mid-premium fixtures, semi-frameless glass): $22,000–$32,000 / 3–5 weeks
Cast-iron tub walk-in conversion (Convert a 1945–1965 built-in cast iron tub-shower to a walk-in): $25,000–$42,000 / 4–6 weeks
1925 bungalow period-appropriate walk-in (Hex mosaic + subway + plaster-and-lath demolition protocol): $28,000–$45,000 / 5–7 weeks
30th Street resale-aware gentrification shower (Designer porcelain, designer fixtures, low-iron glass, optimized for $750K–$985K corridor resale): $30,000–$42,000 / 4–6 weeks
Premium curbless primary walk-in (Curbless linear-drain layout, heated bench and floor, multi-function valve): $35,000–$48,000 / 5–7 weeks
Pricing assumes Iron Crest's standard Sunset scope: City of Boise plumbing and electrical permits (the corridor isn't in a Boise Historic District, so no Historic Preservation review), Schluter Kerdi waterproofing on every shower, EPA RRP lead-safe practices throughout, premium tile and plumbing fixtures, frameless tempered glass, and our 5-year workmanship warranty layered on top of Schluter's lifetime membrane warranty. Properties along the 30th Street corridor or south of West State Street within FEMA's Boise River flood mapping require an additional pre-construction flood-zone review for any work that touches foundation, slab, or substantial scope; we handle that verification at no extra charge.
Sunset / 30th Street is not within any City of Boise Historic District. There is no Historic Preservation Commission review for these neighborhoods. No HOAs for most Sunset streets — historically working-class to middle-class neighborhoods without modern HOA structure.
City of Boise standard permits apply for electrical, plumbing, structural, and mechanical work. Permit timelines are typically 2-4 weeks for over-the-counter scopes and 3-5 weeks for full plan review with structural drawings.
EPA Lead Renovation, Repair and Painting (RRP) Program applies to virtually every Sunset project given the universal pre-1978 construction. Iron Crest carries RRP certification and follows lead-safe work practices including HEPA containment, wet-paste paint scraping, lead-safe disposal.
Asbestos testing required for pre-1980 demolition work. Common in popcorn ceilings, vinyl asbestos floor tile, sheet flooring mastic, pipe insulation, and sometimes original siding products on pre-1980 Sunset homes. Pre-1940 original Sunset bungalows occasionally have plaster-and-lath walls (rather than later drywall) requiring different demolition practices.
Sunset lots are typically smaller than West Boise or Northwest Boise (50'-60' frontage with 110'-130' depth, often 0.13-0.18 acre) but generally accommodate additions and deck work. Setback compliance occasionally constrains larger detached ADU siting on smaller bungalow streets.
Some Sunset properties along the Boise River corridor are subject to flood plain considerations. FEMA flood zone verification required for any work that affects building elevation, foundation, or substantial scope. Iron Crest reviews flood zone status during pre-construction for river-adjacent properties.
30th Street and 27th Street commercial corridors are within City of Boise transit-oriented development planning overlays in some areas. Mixed-use and small multi-family projects subject to specific design review. Pure residential renovation generally not affected.
Boise River Greenbelt easements occasionally affect rear-yard work on properties backing to the river. Iron Crest verifies Greenbelt easement status during pre-construction.
Material decisions in Sunset come down to: pre-1940 bungalow vs. post-war ranch (period vs. modern vocabulary), and primary vs. secondary (heated curbless vs. simpler curb format).
Waterproofing — Schluter Kerdi system, every shower without exception
Lifetime Schluter manufacturer warranty when the system is installed by a Schluter-certified installer. Iron Crest is certified. Kerdi-Shower-T pre-slope on curbless layouts.
Tile — three vocabularies, picked by era
Bungalow vocabulary: 1" or 2" hex mosaic floor + 3×6 subway walls + pencil-liner cap rail. Modern post-war vocabulary: 24×48 marble-look large-format porcelain. Resale corridor vocabulary: designer 12×24 or 24×48 porcelain (Florim, Atlas Concorde, Daltile Marca Corona). Installed cost ranges $14–$45 per square foot depending on tile and pattern complexity.
Plumbing fixtures — period vs. modern split
Period-appropriate (1920s–30s bungalows): House of Rohl Country Bath, Newport Brass Astor, classic polished chrome, cross handles or porcelain lever. Modern post-war and corridor resale: Kohler Memoirs, Moen Genta, Brizo Litze, Hansgrohe Talis.
Glass — frameless tempered, low-iron for resale tier
3/8" frameless tempered standard. Low-iron (Starphire / Ultra-Clear) glass for premium primary and corridor-resale work — eliminates the green tint that reads as cheaper at sale time.
Heated floor and bench — Schluter Ditra-Heat or NuHeat
Standard inclusion on premium primary and 30th Street resale-aware tier. Skipped on secondary baths.
Multi-function shower system — premium primary only
Rain head + handheld + body sprays. Pressure-balanced thermostatic valve. Point-of-use tankless or recirculating loop in homes where the original water heater is across the house — common in 1925 bungalow plans.
Period bungalow features — preservation moves
Salvage and re-mount original integrated cast iron soap dishes when condition allows. Re-create chair-rail tile transitions. Use polished nickel or chrome Crane-style cross handles. These details are why bungalow buyers pay a premium on the 27th–33rd corridor.
Drain — linear for curbless, central for traditional
Linear trench drain (Infinity Drain, Schluter Kerdi-Line) for curbless layouts. Center round drain for curb format. Bungalow restorations sometimes use period-correct chrome strainer drains as a finish detail.
Sunset's pre-1978 housing stock surfaces a predictable set of conditions during demolition. We pre-screen for them in the discovery walkthrough so the budget reflects them up front rather than as change orders.
- •Plaster-and-lath wall system (pre-1940 originals north of State, especially 27th–33rd) Heavier debris, wider dust footprint, can't be cut with a standard drywall saw. Adds 3–5 days to demolition. Plaster repair where we open beyond the shower footprint runs $35–$85 per square foot.
- •Original Crane or American-Standard cast iron tub Often impossible to walk out a 26"-wide bungalow door. Standard practice is break-out demolition in place with a chipping hammer and disposal as construction debris. Cost: $500–$1,500 depending on access.
- •Galvanized supply piping (universal in pre-1965 Sunset, especially Sunset Park and Veterans Park) We re-pipe the wet wall to PEX at minimum. If pressure complaints exist, full house re-pipe is the right move and runs $4,800–$8,500 separately. Standard wet-wall replacement: $1,800–$5,500.
- •Cast iron drain stack Universal in pre-1965 homes. We retain unless cracked, in which case partial replacement is $2,200–$4,800.
- •Pre-1978 lead-paint at adjacent surfaces — applies to every Sunset address EPA RRP containment and HEPA-only sanding required. Cost addition: $1,500–$4,500 depending on disturbed surface area.
- •Asbestos in pre-1980 mastic, sheet flooring, or vinyl asbestos tile under existing flooring Pre-screen testing $300–$700. Licensed abatement when triggered: $2,500–$6,500.
- •Knob-and-tube wiring at bathroom circuits (1920s–early 1940s bungalows) Universal at pre-1940 originals before later rewires. We replace the affected circuit and ground-fault-protect the bathroom. Bath rewire: $2,500–$5,500.
- •Failed waterproofing + hidden mold behind tile board Universal in pre-1990 showers. Felt-paper-only construction was standard until membranes arrived. Mold remediation: $1,500–$5,500 depending on cavity reach.
- •Inadequate ventilation — original bath fans (when they exist) are 50 CFM or non-existent We replace with a high-CFM humidity-sensing Panasonic or Broan unit. $850–$1,800 including new ducting through the roof or a rim joist.
- •Boise River flood-zone status (properties west of 30th and south of West State near the river) FEMA flood-zone verification required when scope touches foundation, slab, or substantial structure. We pull the FIRMette during the pre-construction phase at no charge.
Discovery and design (Weeks 1–2)
On-site walkthrough at the property. Pre-1978 lead pre-screen and asbestos test sample if scope warrants. Era assessment (bungalow vs. post-war vs. infill) sets demolition planning. Material direction conversation calibrated to whether the home is staying with owner or being prepped for resale into the corridor's $750K–$985K band.
Design finalization and ordering (Weeks 2–4)
Detailed layout drawings with curbless or curb decision. Tile and fixture orders. House of Rohl and Brizo lead times run 4–6 weeks; we order before permitting starts so the trades schedule lines up.
City of Boise permits (Weeks 3–5)
Plumbing and electrical permits over the counter. No Historic Preservation review — Sunset isn't within a designated Boise Historic District. FEMA flood-zone verification on river-adjacent properties.
Demolition (Days 1–4 of work)
EPA RRP containment up. Cast iron tub break-out in place where access is tight. Plaster-and-lath protocol on pre-1940 originals (different cuts, heavier disposal). Knob-and-tube identified and isolated.
Plumbing and electrical rough-in (Days 4–8)
Wet-wall galvanized-to-PEX re-pipe. New shower valve set with anti-scald thermostatic mixer. Bathroom branch-circuit replacement where knob-and-tube was present. City of Boise plumbing and electrical rough-in inspections.
Substrate and waterproofing (Days 8–14)
Cement board substrate. Schluter Kerdi membrane on every wall and floor. Kerdi-Shower-T pre-slope on curbless layouts. Heated floor mat (Ditra-Heat or NuHeat) on premium primary scope.
Tile install (Days 14–25)
Floor tile, wall tile, bench tile, niche. Bungalow tier sets the period vocabulary (hex + subway + cap rail) and takes longer than the modern format. Grout and caulk per Schluter spec.
Glass templating and fabrication (Days 25–35)
Glass templated only after tile is set and grouted. Fabrication 5–10 business days. Low-iron upgrades extend by 2–3 days.
Fixtures, glass, and trim (Days 35–45)
Plumbing fixture install. Glass install. Lighting trim. On bungalow-tier work, this includes period chrome trim and any salvaged-soap-dish remount.
Final walkthrough and warranty (Days 45–55)
Final inspections by City of Boise. Punch-list closure. 5-year Iron Crest workmanship warranty begins. Schluter membrane warranty is lifetime through the manufacturer.
Sunset shower work needs a contractor fluent in three distinct vocabularies — pre-1940 plaster-and-lath bungalow restoration, post-war cast-iron-tub conversion, and 30th Street corridor resale-tier specification. It also needs Schluter certification, EPA RRP, and a working relationship with City of Boise plumbing and electrical inspectors.
- City of Boise Planning & Development Services — Building, electrical, plumbing, mechanical permits.
- EPA Lead Renovation, Repair and Painting (RRP) Program — Required certification for pre-1978 paint disturbance work — applies to virtually every Sunset project.
- City of Boise Parks — Boise River Greenbelt — Greenbelt easement information for river-adjacent Sunset properties.
- Idaho Power Energy Efficiency Programs — Rebates and incentives for insulation, window replacement, HVAC upgrades. Strong ROI for energy retrofits on 1920s-60s Sunset homes.
- Idaho DEQ Air Quality (Asbestos) — Testing and abatement guidance for pre-1980 homes.
- Idaho Division of Building Safety — Contractor Search — Verify contractor RCE license, bonding, and insurance through the official Idaho database.
How much does a shower remodel cost in Sunset?
Roughly $22,000–$32,000 for a secondary or hall bath; $25,000–$42,000 for the most common scope (cast-iron tub-to-walk-in conversion); $28,000–$45,000 for a period-appropriate walk-in in a 1925 bungalow with plaster-and-lath demolition; $30,000–$42,000 for a 30th Street corridor resale-aware build; $35,000–$48,000 for a curbless heated premium primary. Final number depends on era, finish tier, and discovery work surfaced during demolition.
How long does the project take?
3–5 weeks for a secondary bath, 4–6 weeks for a standard tub-to-walk-in conversion, 5–7 weeks when plaster-and-lath demolition or curbless heated primary scope is involved. Pre-1940 bungalow demolition adds 3–5 days versus drywall homes.
What's different about remodeling a Sunset shower vs. another Boise neighborhood?
Three things: every address triggers EPA RRP because the entire corridor predates 1978; pre-1940 originals (mostly the streets between 27th and 33rd north of West State) have plaster-and-lath wall systems that need a different demolition protocol than drywall; and the corridor's value curve has pulled comparable sales into the $750K–$985K band, which changes the math on premium fixture and tile spend.
Can the original cast iron tub be removed without tearing out a doorway?
Yes — break-out demolition in place with a chipping hammer is our standard practice on bungalow streets where the tub physically cannot fit through a 26" doorway. Cost: $500–$1,500. We dispose of the cast iron as construction debris.
Do you do period-appropriate bungalow walk-ins for the 1925-era homes?
Yes — 1" or 2" hex mosaic floor, 3×6 subway walls to chair-rail height with a pencil-liner cap, classic chrome cross-handle valve from House of Rohl Country Bath or Newport Brass Astor, frameless 3/8" tempered glass for modern function. Where original integrated cast iron soap dishes survive, we'll salvage and remount them on request.
Can the walk-in be curbless?
Yes — strongly recommended for premium primary and the 30th Street corridor resale tier. Requires a linear trench drain, proper substrate slope, and Kerdi-Shower-T pre-slope. Bungalow streets sometimes can't accommodate the curbless layout because of original framing depth; we assess in the discovery walkthrough.
What's the deal with Schluter Kerdi?
Schluter Kerdi is the waterproofing membrane system we install on every shower without exception. It carries a lifetime manufacturer warranty when installed by a certified installer (Iron Crest is certified). The 1925–1970 housing stock in Sunset originally used felt-paper-only construction, which is why we see universal failed waterproofing in the existing showers we tear out.
What about hidden mold?
Universal in pre-1990 Sunset showers because of the failed felt-paper waterproofing. We assess after demolition exposes the cavity and remediate as needed. Range: $1,500–$5,500 depending on how far moisture has migrated into adjacent framing.
Is my property in the Boise River flood zone?
Some properties west of 30th and south of West State are inside FEMA's Boise River flood mapping. When scope touches foundation, slab, or substantial structure, we pull the FIRMette during pre-construction at no extra charge to verify before the design is finalized.
What's the warranty?
5-year Iron Crest workmanship warranty plus the Schluter Kerdi membrane lifetime manufacturer warranty. Workmanship warranty starts at final walkthrough.
