Hidden Hills bathrooms tend to run larger and more feature-dense than the LA average — a primary bath is often 200 to 600+ square feet, with a walk-in or zero-threshold shower, a freestanding soaking tub, a double-vanity run, a dedicated makeup station, heated floors, and in many cases an integrated steam generator and dressing room that coordinate with the bathroom design rather than sitting separately. The design starts by matching the new bathroom to the home's architecture. A Hidden Hills a Spanish Colonial Revival primary bath reads differently from a mid-century ranch primary bath, and we measure, photograph, and document the whole home on the first visit so the result is continuous with the house.
Material and fixture selection happens early. Imported marble and stone slabs — Calacatta, Statuary, Arabescato, Taj Mahal, Bianco Dolomiti — typically carry 6 to 10 week lead times from slab selection to fabrication-ready. Luxury fixture brands common in Hidden Hills primary bathrooms (Kallista, Waterworks, Dornbracht, Perrin & Rowe, THG, Samuel Heath, Lefroy Brooks, AXOR) range from in-stock to 12+ weeks depending on configuration. Custom vanity millwork typically runs 8 to 14 weeks. Those lead times drive the whole construction schedule.
Every Hidden Hills bathroom design includes detailed 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 handles every trade so scheduling stays tight and accountability stays clear throughout the build.
Waterproofing is the non-negotiable layer underneath every good bathroom. In Hidden Hills 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 and includes vapor-sealed transitions where the steam generator plumbing runs. Those details are invisible when the room is finished, but they are what separates a bathroom that holds up for decades from one that fails silently behind the tile.
Permit jurisdiction for Hidden Hills bathroom remodels runs through LA County Public Works Building & Safety — not LADBS. We handle the full permit process from plan submission through final inspection and coordinate directly with LA County inspectors. Interior-only bathroom work on non-designated properties generally does not trigger the Hidden Hills Community Association (HHCA) architectural review, which reviews exterior changes visible from the public right-of-way. Bathroom work on an individually landmark-designated property adds an LA County Historic Preservation review layer where applicable, which we manage in parallel.
Hidden Hills bathrooms finish at a higher spec than the LA average. Imported marble and stone slab shower surrounds, custom vanity millwork in premium woods and specialty finishes, frameless glass enclosures, Kallista/Waterworks/Dornbracht-tier fixture packages, heated floors and heated towel bars, steam generators with vapor-sealed detailing, freestanding soaking tubs, and integrated medicine cabinets with interior outlets are standard expectations rather than upgrades. That finish level raises cost per square foot, but it also means the finished bathroom reads as a permanent, intentional part of a premium home rather than a one-cycle refresh.
Every Hidden Hills bathroom remodel passes LA County Public Works 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.
Hidden Hills. Hidden Hills is a small incorporated city within LA County but contracts its Building & Safety work to LA County, so permits and inspections route through LA County Public Works Building & Safety, not LADBS. City of Hidden Hills Planning handles zoning and site design review, and the Hidden Hills Community Association (HHCA) separately runs architectural review via the community's CC&Rs on any change visible from common areas or the gates. Hillstar runs all three tracks in parallel so the homeowner gets one coordinated timeline.
Industry-standard waterproofing on every shower and tub surround is baseline for any Hidden Hills 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 are what separates a bathroom that holds up for decades from one that fails silently behind the tile.
Usually no. The Hidden Hills Community Association (HHCA) architectural review reviews exterior design changes visible from the public right-of-way, not interior renovations. A standard bathroom remodel that stays inside the existing building envelope typically doesn't reach HHCA review. Work that adds exterior windows, changes visible fenestration, or extends the house footprint may trigger review, and we flag those elements at the design phase. Bathroom work on an individually landmark-designated property adds an LA County Historic Preservation review layer where applicable, which we manage in parallel.
Imported marble and stone for primary bathrooms — Calacatta, Statuary, Arabescato, Taj Mahal, Bianco Dolomiti — typically runs 6 to 10 weeks from slab selection to fabrication-ready. Luxury fixture brands common in Hidden Hills primary bathrooms (Kallista, Waterworks, Dornbracht, Perrin & Rowe, THG, Samuel Heath, Lefroy Brooks, AXOR) range from in-stock to 12 or more weeks depending on finish and configuration. Custom vanity millwork typically runs 8 to 14 weeks. Steam generators, heated-floor systems, and integrated medicine cabinets need to be specified early because late changes on those items create framing and plumbing rework. More on broader bathroom planning is in our bathroom projects planning guide.
Guest or powder refreshes — new vanity, tile, fixtures, and lighting without moving plumbing — typically run $40K to $100K in Hidden Hills. Full primary bathroom remodels with walk-in or zero-threshold showers, freestanding tubs, imported stone, heated floors, and luxury fixtures typically run $100K to $300K. Ground-up custom primary suites with steam, dedicated dressing rooms, scullery-level millwork, and top-tier fixture packages commonly reach $300K to $1.5M or above. Finish and fixture selection drives the spread more than construction scope. We provide a written cost breakdown at the consultation so every line item is visible.

Yes, and in Hidden Hills it is common to run primary bathroom, kitchen, and a broader home remodeling project as a single coordinated scope. Running all the work together under one LA County Public Works Building & Safety permit package lets the same crew sequence framing, plumbing, electrical, tile, cabinetry, and finish work across the house, which typically finishes faster and at lower combined cost than running the projects back-to-back.
Lior and his team were extremely courteous, prompt, and worked hard to make sure every element was exactly what we were looking for.
— Ian, October 2022I enjoyed working with Lior as my contractor because he always answered all my questions. He explained the process and was helpful throughout.
