Why Hillstar
Why Hidden Hills Estates Choose Hillstar
Bathrooms here are estate rooms — large, custom, and reviewed. The build has to match the standard the community holds.
City + HHCA Together
The City of Hidden Hills issues the permit; the Community Association reviews what's visible. We prepare and file both submissions as one package.
Custom Suite Capability
Steam, stone slabs, freestanding tubs, double vanities, dressing-room adjacencies — detailed like the custom homes they live in.
Quiet, Managed Logistics
Gated access, private streets, and equestrian traffic set the rules for crews and deliveries. We respect all three.
Membrane-Sealed Wet Areas
Ceiling-height waterproofing on steam enclosures, pre-sloped pans, and sealed transitions everywhere water lives.
Septic-Aware Design
Where a property runs on septic, fixture counts and drain moves are checked against the system before drawings finalize.
Single-Team Delivery
One crew and one point of contact from design through the city's final inspection.

FAQ
Hidden Hills Bathroom Remodel — FAQ
City permits, HHCA review, steam and stone construction, septic checks, and how estate-level budgets are structured.
How do permits work in Hidden Hills?
The City of Hidden Hills issues building permits — LADBS has no role here. On top of that, the Hidden Hills Community Association reviews exterior-visible changes through its architectural committee. Interior bathroom work usually needs only the city; when both apply, we file the two submissions together so neither waits on the other.
Does an interior remodel really involve the HOA?
Usually not. A remodel that stays inside existing walls typically proceeds on the city permit alone. The HHCA layer matters when a window changes, a vent penetrates a visible roof plane, or the exterior envelope moves — and we flag that during design, not after.
Can you handle steam showers and large-format stone?
Yes. Steam enclosures get vapor-sealed, ceiling-height membrane assemblies; slab and large-format work gets the substrate flatness and layout planning it demands. The panel, water heating, and generator capacity are confirmed during design.
Our property is on septic. What does that mean here?
It means fixture additions and drain relocations get checked against the septic system's capacity and layout first. We verify what your lot runs on during feasibility so the design never outruns the infrastructure.
What does a project like this cost?
Custom suites are quoted after a site visit, itemized line by line — fixtures, stone, labor, and contingencies visible from the start. Changes are priced and approved in writing before they're built. That format holds whether the scope is a refresh or a full suite rebuild.
