Tier one same-footprint primary rebuild lands at $42,000 to $68,000. Tier two with steam shower, heated floors, and Mediterranean finish at $72,000 to $98,000.

Bath remodels that reposition windows or add a window to capture a lake or hillside view trigger an ARB submittal. We prepare the package — color elevations, material samples, the architectural narrative — and the ARB reviews against the Mediterranean architectural standard. Window changes get scrutinized for roofline congruence and exterior color palette match. Lake Sherwood and Westlake Island parcels have additional covenant review. The ARB submittal adds about three weeks to the timeline. We have 100% approval on the seven Westlake Village ARB submittals we have filed for bath scopes since 2024.Wet-Area Waterproofing on 1985-2002 Estate Construction
Two out of three Westlake Village bath remodels we open up find water damage behind the original tile — standard for the 1985-2002 construction era. Mortar-bed tile installs failed at the curb, behind the soap niche, and at the tub-deck joint. The water sits in the subfloor and the framing rots over decades. Our standard bath scope includes selective demo of the wet wall, framing and subfloor inspection, and a code-compliant rebuild of any damaged material before we install the new waterproofing assembly. That adds an average of $4,800 to a Westlake Village bath remodel. We carry it as a clearly identified line item, not buried in contingency. Estate owners want to see the number.Why Westlake Village Estate Owners Pick NPLD
Westlake Village estate primary baths are an architectural-detail-heavy build. The hand-troweled plaster on the walls. The honed-stone double vanity. The window-aligned freestanding tub. The hand-glazed tile feature wall. Most bath remodel specialty shops cannot run that finish stack. We can, because the architectural-firm DNA from 2016 forward gave us the design vocabulary and the trade relationships, and the CSLB General B from 2023 gave us the integrated build capability. The bid is line-item fixed at signing. The documentation at closeout is the architect-firm standard — stamped drawings on any structural change, cut sheets on every product, code reference sheet, photographic progress log, and a one-year walk-through. The schedule holds because the trades run in-house under the General B. Call 818-605-1388 — phone, text, web — 24/7.The Estate Bath Closeout Packet — 2026 Standard
Every Westlake Village bath remodel ships with a closeout packet built to estate-tier 2026 documentation standards: as-built drawings showing the final wet-area layout; stamped structural drawings if a wall was moved or a window was added; cut sheets for every fixture, stone, and finish selection installed; the ARB submittal record and approval letter if exterior elements changed; the code reference sheet keyed to 2025 California Building Code and California Electrical Code; the photographic progress log keyed to the rough-in and final inspections; the Ventura County Building signoff card; and the one-year walk-through commitment. Estate primary baths get a five-year warranty on the waterproofing assembly and a two-year warranty on the finish work. The architectural-firm DNA from 2016 forward built this discipline. The packet and warranty are in the bid — no upcharge.Bathroom Remodeling Questions Homeowners Ask About Bathroom Remodeling in Westlake Village

Can you build the Mediterranean estate finish stack in a bath?
