Fast, Reliable Bathroom Remodeling Across Sausalito
A full bathroom remodel in Sausalito typically runs $9,000 – $28,000, with small bathrooms landing between $5,000 and $12,000. The bigger question is what your specific home will need once walls come down, and that’s where local experience lines up with the number we write down. If you live in the floating home community along Richardson Bay, in a mid-century hillside house off Bridgeway, or in a compact condo near Caledonia Street, call (936) 259-2607 for a free estimate. We serve Sausalito with background-checked, uniformed crews and a live person answering the phone around the clock.
Why Penhallow Remodeling Is Sausalito’s Preferred Bathroom Remodeling Company
Trevor Nash runs Penhallow Remodeling around a simple rule: written price before work starts, written guarantee with every job. Sausalito homeowners deal with two very different building conditions depending on whether they live hillside or on the water, and most remodeling companies only know one of them. We know both.
Our Bathroom Remodeling team works inside the BCDC 100-foot shoreline band on floating homes and Bridgeway waterfront properties, where a separate Bay Conservation and Development Commission permit applies before the City of Sausalito even reviews plans. We also do hillside remodels on post-and-beam homes stepping down steep grades, where equipment access, drainage, and structural reinforcement change how a bathroom gets framed and waterproofed. That dual fluency is not something a contractor picks up from a training manual.
Every project includes the 365-Day Done Right Promise: if something fails inside the guarantee window, we return and fix it at no charge. That promise is written, not implied. And if a repair fails, the second visit is free, no service call fee, no re-inspection charge.
Small Bathroom Remodel in Sausalito
A Small Bathroom Remodel in Sausalito usually means working within 35 to 50 square feet, often in a mid-century hillside home or a floating home where every inch is accounted for. These projects run $5,000 – $12,000 and are the most common request we field from homeowners near Waldo Point, the Banana Belt, and the condos along Bridgeway. The budget is smaller, but the same permitting and moisture rules apply.
What the Job Involves
You re-tile the shower surround, swap a vanity, replace a toilet, upgrade the exhaust fan, and often re-waterproof the entire wet wall. In Sausalito, we spec marine-grade fasteners and a waterproofing membrane like a Schluter system because salt fog from the Bay accelerates corrosion on standard hardware. The vanity and tile choices matter, but the waterproofing does the real work.
What We Write Before Work Starts
Your written estimate includes line items for demolition, waterproofing, plumbing rough-in, electrical, tile, fixtures, and finish carpentry. If your home sits within the BCDC shoreline band, we note the permit requirement on the first page of the quote. Allowances cover what opening the wall will likely expose, so the number you approve is the number you pay unless we uncover something structural and bring it to you in writing first.
Shower Remodel in Sausalito
A Shower Remodel in Sausalito starts at $3,000 for a straightforward shower replacement and reaches $8,500 – $12,000 when you convert a tub to a walk-in shower or install a frameless glass enclosure. Homes near the water, especially along Gate 5 Road and the floating home berths, need marine-grade hardware and a waterproofing approach that holds up to persistent salt fog and humidity.
Walk-In Showers and Tub-to-Shower Conversions
Walk-in shower installation in Sausalito runs $4,500 – $12,000 depending on tile choices, glass, and whether we move plumbing. A tub-to-shower conversion runs $3,500 – $10,000. If you live on a hillside lot where the original tub sits against an exterior wall, expect us to inspect the framing and sheathing behind it before quoting the finish work.
Frameless Glass and Enclosures
Frameless glass shower enclosures are popular in Sausalito because they open up a small bathroom visually. We install them with stainless or marine-grade hardware and confirm the glass meets code for tempered safety glazing. The enclosure is the final layer, but we set the curb, pan, and tile first so there are no surprises when the glass goes up.
Trusted Brands We Service in Sausalito
We install and service fixtures and materials from Kohler, Moen, Delta, Toto, and Cambria. Our crews are trained on these product lines, which means warranty work and replacement parts move faster when we are already familiar with the valve body or drain assembly. For Sausalito customers, we keep commonly needed parts accessible through our Bay Area supply network, so a Kohler cartridge or a Moen trim kit does not stall the finish schedule. We also service homes built with ADU systems from Dvele and Mighty Buildings, including their factory-installed bath modules.
Common Bathroom Remodeling Problems We See in Sausalito Homes
- Salt-corrosion on rough-in hardware. Bathrooms near the Bay corrode fasteners and metal shower pans faster than inland homes. We open walls and routinely find rusted nails, failing flashing, and corroded supply lines in homes only 15 or 20 years old.
- Undersized framing on mid-century hillside lots. Post-and-beam homes off lower Bridgeway and steep streets above downtown often have cripple walls and load-bearing framing that was not sized for a second story or the lateral loads of a remodel. A shower pan that flexes on soft framing cracks the tile within a season or two.
- Waterproofing failures behind original tile. Older Sausalito homes had green board or drywall behind shower tile, not a true waterproofing membrane. When the grout eventually lets moisture through, the substrate rots, and the rot spreads into the subfloor before you see any visible damage.
- BCDC permit conflicts on floating homes. Any bathroom work inside the 100-foot shoreline band requires a BCDC permit and a maximum feasible public access finding before the City of Sausalito will issue its own permit. Contractors who skip that layer stall the project for months.

FAQs About Bathroom Remodeling in Sausalito
Yes. Any bathroom remodel inside the BCDC 100-foot shoreline band requires a Bay Conservation and Development Commission permit plus maximum feasible public access findings before the City of Sausalito will process its own building permit. We prepare both submittals together so the project does not stall waiting on one agency. Call (936) 259-2607 to see if your address falls inside the band.
In homes built between the 1940s and 1960s, we routinely find undersized load-bearing framing, cloth-wrapped wiring, failed shower pans, and water-damaged subfloor. That is why our written Sausalito estimates include allowances for framing repair, electrical rough-in, and subfloor replacement rather than hitting you with a surprise change order after demolition. We price the likely scope up front and confirm any actual change in writing before we do the work.
Salt-laden fog from the Bay accelerates corrosion on fasteners, flashing, and metal connectors far faster than in Mill Valley or Corte Madera. We spec marine-grade stainless hardware, corrosion-resistant shower valves, and a true waterproofing membrane on every Sausalito rough-in because standard galvanized parts break down within a few seasons. That is a materials choice, not an upsell.
A full bathroom remodel runs $9,000 – $28,000, a small bathroom $5,000 – $12,000, and a walk-in shower installation $4,500 – $12,000. Quotes move when opening the walls exposes framing damage, cloth wiring, rotted subfloor, or when the BCDC permit adds plan-review time. We write allowances into the original contract so those realities are priced from day one, not discovered after you sign.
We pull all required permits before demolition and schedule City of Sausalito inspections plus BCDC findings when the property sits in the shoreline band. After the final inspection, we walk the room with you and hand over the written 365-Day Done Right Promise. If anything fails inside that window, we return at no charge. Call (936) 259-2607 to schedule a free estimate.
If you have an aging Sausalito bathroom that needs a real, written price and a guarantee to match, call Penhallow Remodeling at (936) 259-2607. Trevor Nash and our crew will inspect it, explain what the walls are likely hiding, and give you a number you can hold us to.
