Hillstar Construction delivers custom bathroom remodels for Altadena homeowners. Our office sits on Ventura Boulevard in Woodland Hills — we travel to Altadena projects for the first site visit and stay engaged through every inspection. We work across individually landmark-designated properties and craftsman districts like Janes Village and the Country Club area, the foothill custom-build corridor, the western foothill blocks along Chaney Trail, post-war east-Altadena blocks, the Mariposa Junction commercial corridor, and surrounding 91001 and 91003 addresses on guest and powder refreshes, full primary bathroom renovations, and ground-up custom primary suites — including preservation-grade craftsman bathrooms inside Janes Village and the other LA County landmark designation.

Altadena bathrooms run an exceptionally wide scope — from compact pre-war hall baths in Janes Village craftsman homes to 200-plus-square-foot primary suites in updated the foothill custom-build corridor and West Altadena custom properties. The design starts by matching the new bathroom to the home's architecture. Craftsman homes call for period-appropriate tile patterns, stained wood vanities, paneled detailing, and bungalow-era fixtures. Spanish Colonial Revival homes land on painted cabinetry, terracotta or patterned tile, and arched detail. Tudor and Prairie-style homes have their own vocabularies. East Altadena mid-century homes lean toward flat-panel vanities with clean-line stone. the foothill custom-build corridor and West Altadena custom bathrooms reach for imported stone, heated floors, steam, and fully integrated fixture packages.
Material and fixture selection happens early. Custom vanity millwork runs 6 to 12 weeks from approved drawings; preservation-grade craftsman millwork runs 10 to 16 weeks. Imported stone slabs (Calacatta, Taj Mahal, Bianco Dolomiti) run 6 to 10 weeks. Fixture brands common in Altadena primary bathrooms — Kohler, Moen, Grohe, Hansgrohe, Kallista, Waterworks, Perrin & Rowe — range from in-stock to 12-plus weeks.
Every Altadena bathroom design includes drawings, tile and stone samples, a full fixture and plumbing schedule, and a written cost breakdown before any demolition. Scope changes mid-build are documented and priced in writing so the final invoice matches the approved scope.
Our crew handles demolition, plumbing, waterproofing, electrical, and tile installation in-house. One team sequences every trade so scheduling and accountability stay tight.
Waterproofing is the non-negotiable layer underneath every good bathroom. On Altadena projects we use sheet-membrane or liquid-applied membrane systems behind every shower and tub surround, fully sealed at corners, transitions, and drain assemblies, with dedicated pre-slope and waterproofed curbs for walk-in and zero-threshold showers. On primary baths with steam the waterproofing scope extends to the ceiling with vapor-sealed transitions where the steam generator plumbing runs. Altadena's craftsman bungalows and pre-war homes often require extra attention — original plumbing in those homes may include galvanized supply lines, cast-iron waste, and subfloor moisture history under the existing tile that needs to be addressed before new work goes down. These details are invisible when the room is finished, but they're what separates a bathroom that holds up for decades from one that fails silently behind the tile.
Permit jurisdiction for Altadena bathroom remodels runs through LA County — not LADBS (that's the City of LA). Altadena is unincorporated Los Angeles County: permits, plan checks, and inspections route through LA County Public Works Building & Safety. Post-Eaton-Fire rebuild bathrooms use the County's expedited fire-rebuild permit pathway. Bathroom work on individually landmark-designated homes, or on character-contributing blocks like the Christmas Tree Lane corridor, may trigger LA County historic review for any change affecting character-defining features. Interior bathroom updates that preserve original millwork, period tile layout, and window proportions typically clear review cleanly.
Altadena bathrooms finish at a spec that tracks the home's architectural pedigree. Craftsman-bungalow bathrooms in Janes Village and the LA County landmark designation reach for preservation-grade detailing: bungalow-style hex or subway tile, stained wood vanities with paneled fronts, period fixture silhouettes, and carefully hidden plumbing and electrical upgrades. Spanish and Tudor bathrooms maintain their own period vocabularies. the foothill custom-build corridor and West Altadena luxury primary suites land at Beverly-Hills-tier imported stone, steam, heated floors and towel bars, and Kallista/Waterworks/Perrin & Rowe fixture packages. East Altadena mid-century bathrooms emphasize clean-line stone and minimalist fixtures.
Every Altadena bathroom remodel passes LA County Building & Safety final inspection and carries Hillstar Construction's workmanship guarantee. We walk the completed bathroom with you before closing out the project, document every punch-list item, and stay on the job until every line item is resolved to the approved scope.
Altadena directly. Altadena is an unincorporated community in Los Angeles County, so permits don't go through LADBS or a city building department — they route through LA County Public Works Building & Safety, with hillside and historic review (where applicable) through LA County Regional Planning. Every permit, plan check, and inspection for an Altadena bathroom remodel goes through the County. Hillstar handles the full submission and inspection coordination directly with LA County staff.
Industry-standard waterproofing on every shower and tub surround is baseline for any Altadena bathroom we build. We use sheet-membrane or liquid-applied membrane systems behind tile, fully sealed at corners, transitions, and drain assemblies, with dedicated pre-slope and waterproofed curbs for walk-in and zero-threshold showers. On primary baths with steam the waterproofing scope extends to the ceiling and includes vapor-sealed transitions where the steam generator plumbing runs. These details are invisible when the room is finished, but they're what separates a bathroom that holds up for decades from one that fails silently behind the tile.
Altadena is unincorporated LA County and does not use the LA County landmark designation (LA County landmark designation) system (that's a City of Pasadena and City of LA framework). Historic review in Altadena runs through LA County's Historic Preservation Ordinance and applies to individually listed landmarks (National Register, California Register, or LA County Historic Landmark). The most visible heritage corridor is Christmas Tree Lane on Santa Rosa Avenue — California Historical Landmark #990. If your home is individually designated or on a character-contributing block, any remodel affecting character-defining features requires LA County historic review alongside the standard Building & Safety permit. A bathroom remodel that updates plumbing, waterproofing, tile, vanity, and fixtures within the existing spatial geometry and preserves period character typically clears County review cleanly. We confirm designation status at the first visit.
Often yes. Altadena's craftsman bungalows and pre-war homes — especially in individually landmark-designated properties and craftsman districts like Janes Village and the Country Club area, designated heritage blocks, and the Meadows — frequently still carry galvanized supply lines, cast-iron waste stacks, original lead-and-oakum drain joints, and subfloor moisture history under the existing tile. A full bathroom remodel on one of these homes typically includes replacing supply and waste runs back to the stack, rebuilding the subfloor where moisture damage is found, and sometimes upgrading the service panel circuit feeding the bathroom. We open the floor and walls early in the project, document what we find, and price the plumbing and subfloor scope in writing before tile and fixtures are committed — so there are no surprise change orders mid-build.
Custom vanity millwork typically runs 6 to 12 weeks from approved drawings; preservation-grade craftsman millwork runs 10 to 16 weeks. Imported stone (Calacatta, Taj Mahal, Bianco Dolomiti) runs 6 to 10 weeks. Fixture brands common in Altadena bathrooms (Kohler, Moen, Grohe, Hansgrohe, Kallista, Waterworks, Perrin & Rowe) range from in-stock to 12-plus weeks depending on configuration. Steam generators, heated-floor systems, and integrated medicine cabinets need to be specified early since late changes create framing and plumbing rework. On LA County landmark designation projects we also build in time for LA County historic preservation review.
Guest or powder refreshes — new vanity, tile, fixtures, and lighting without moving plumbing — typically run $30K to $75K in Altadena. Full primary bathroom remodels with walk-in or zero-threshold showers, freestanding tubs, stone, and heated floors typically run $75K to $200K. Ground-up custom primary suites with steam, dedicated dressing areas, and higher-spec fixture packages commonly reach $200K to $500K. Janes Village and other LA County landmark designation craftsman bathroom remodels trend toward the higher end of each range when the scope includes plumbing replacement, period-appropriate detailing, and LA County historic preservation review coordination. the foothill custom-build corridor and West Altadena luxury primary suites can exceed these ranges. We provide a written cost breakdown at the consultation.
Lior and his team were extremely courteous, prompt, and worked hard to make sure every element was exactly what we were looking for.
