Sierra Madre Bath Remodel 2026 | $32K-$95K, HPC + Bungalow

A Sierra Madre bathroom remodel inside a Craftsman bungalow is a design problem most GCs handle by ripping out everything original and installing a generic spa look that does not belong in the house. We do not work that way. The bungalow bathroom — even when it has been compromised by a 1970s or 1990s renovation — usually has an opportunity to come back to something that fits the architecture, holds up for the next thirty years, and gives the household a room they actually want to use. NPLD has been designing in Los Angeles since 2016 and licensed as a CSLB general contractor since 2023, with over 200 LA County builds completed. Our Sierra Madre bathrooms run $32K-$95K over a 5-9 week construction window, pulled through the Sierra Madre Building Department directly with HPC review sequenced before construction documents are finalized if the scope triggers it.

What a Sierra Madre Bath Remodel Costs in 2026

Three honest tiers. The entry tier, $32K-$50K, is a hallway or guest-bath refresh inside the existing footprint: period-correct hex or subway tile, a restored or properly-replaced clawfoot or built-in tub, a real porcelain vanity with a marble or honed-quartzite top, a Schluter-membraned tile shower if a shower is in scope, period-correct fixtures (cross-handle or lever, polished nickel or unlacquered brass), and a properly-sized humidistat-controlled exhaust. The mid tier, $50K-$72K, is a primary-bath rebuild: curbless walk-in shower in slab walls or period-correct tile, a freestanding cast-iron tub, dual vanity in custom millwork that matches the bungalow's other built-ins, heated floor zone, and a separate water closet. The top tier, $72K-$95K, is a full primary suite reconfiguration inside the bungalow envelope: structural footprint adjustment coordinated with HPC review, picture-window soaking tub, steam shower, custom millwork, and walk-in closet integration. Permits and HPC review add $1.8K-$5K.

Period-Correct Tile, Fixtures, and the HPC Review

A Sierra Madre Craftsman bath has design vocabulary that most contemporary remodels ignore. Subway tile in 3x6 or 4x4, hex floor tile in 1-inch or 2-inch, wainscot capped with a chair rail, period-correct cross-handle or lever fixtures in polished nickel or unlacquered brass, a cast-iron tub (clawfoot or built-in skirted), a porcelain pedestal sink or a wood-framed vanity with a marble top — these are the details that make the bath belong in the house. They are not more expensive than a generic spa renovation; they just require a GC who knows the period and sources materials accordingly. The HPC review applies to bathrooms when the remodel touches an exterior window or wall, removes a historically-significant interior fixture (original cast-iron tub, original porcelain pedestal, original wainscot), or expands the footprint beyond the existing room. We sequence HPC review before construction documents are finalized so design decisions are not reversed at the wrong moment.

Moisture, Slab Walls, and What Fails in a 1915 Bungalow Bath

The most common bath failure we tear out in Sierra Madre is a 1970s or 1990s renovation that used drywall behind the tile, undersized exhaust, and a mid-tier acrylic tub-shower combo. By year ten the tile is failing, the substrate is rotted, the original studs underneath have moisture damage, and the bath has to come out. We do not rebuild this way. Shower assemblies use a Schluter Kerdi or equivalent waterproofing membrane over cement board, with sealed corners and a pressure-tested drain assembly before tile lay-up. The original studs and floor framing get inspected, sistered if needed, and properly flashed against future moisture. Exhaust is sized for the room cubic footage with a humidistat that runs the fan until the bath dries — not a fixed timer. The result is a bath that fits the architecture and lasts thirty years.

• Period-correct subway or hex tile (handmade or premium): $18-$42/sf installed
• Schluter Kerdi waterproofing on full shower envelope: $2K-$4K (do not skip this)
• Restored or new cast-iron clawfoot tub: $2.5K-$8.5K
• Polished-nickel or unlacquered-brass cross-handle fixtures: $2K-$6K full set
• Heated floor zone (electric): $1.6K-$3.5K
• Properly-sized exhaust with humidistat (110-150 CFM): $650-$1,400 installed

Sierra Madre Permits and How We Sequence

Sierra Madre bathroom remodels inside the existing footprint typically need a combination permit for plumbing, electrical, and mechanical pulled through the Sierra Madre Building Department. Plan check runs 3-5 weeks for non-structural work. If HPC review is triggered (exterior window, footprint expansion, removal of historically-significant fixtures), HPC review precedes plan check and adds 4-8 weeks depending on the HPC meeting schedule. We sequence the permit packet so it goes in finished — Title 24 2022 documentation, gas-line load if a tankless water heater is involved, electrical load calc if heated floors and high-CFM exhaust push panel capacity, and the HPC review package if needed. Construction runs 5-9 weeks once permits clear. The dust barrier, the HEPA scrubber, and the isolated HVAC return keep demo dust from migrating to the rest of the bungalow.
