Why Penhallow Remodeling Is Tiburon’s Preferred Bathroom Remodeling Company
We write the price down before a single cabinet is pulled. That’s the Kingswell standard Trevor Nash runs every Penhallow job by, and it’s the reason Tiburon homeowners who’ve been burned by verbal estimates call us first. The number on day one is the number on the invoice.
Tiburon’s housing stock, mostly 1950s – 1980s post-war hillside ranches and custom residences stepped into steep slopes, throws surprises at contractors who don’t know the peninsula. We do. Corroded galvanized supply lines behind a 1970s hall bath wall near Reed School. Cloth-wrapped wiring that fails the first rough-in inspection. A subfloor that’s been soaking through a failed shower pan for years. We’re not surprised by any of it, and we carry allowances in the contract so you’re not surprised by the bill.
Every technician who walks into your home is background-checked and in uniform. You know exactly who’s there. And a live person answers the phone 24/7, not an answering service, not a voicemail maze. That matters when a bathroom is torn apart and you have a question at 6 a.m.
Bathroom Remodeling Companies in Tiburon
Bathroom Remodeling Companies in Tiburon work under conditions that don’t exist a few miles inland. The peninsula’s three-sided bay exposure means salt-laden marine air degrades fasteners, drain flanges, and tile backer in exterior-facing bathrooms faster than in Corte Madera or Mill Valley. A bathroom remodel here isn’t just cosmetic – opening a wall usually turns up corroded galvanized supply lines, failed waterproofing, or framing that won’t carry a new tile bed. A typical bathroom remodel in Tiburon runs $9,000 – $28,000, with the spread driven by whether the rough-in can be reused or must be replaced.
Full Bathroom Remodeling
We gut the bath to the studs when the tile bed is compromised or the layout no longer works. Everything from new subfloor and waterproofing to vanities, fixtures, and finish tile. The $9,000 – $28,000 range covers most Tiburon full remodels, but a hillside home with custom glass and Cambria or Silestone tops can push higher.
Small Bathroom Remodeling
Powder rooms and hall baths under 40 square feet usually run $5,000 – $12,000 in Tiburon. We replace the vanity, mirror, lighting, and floor tile without moving walls. A live person answers the phone at (936) 259-2607 if you want a ballpark specific to your house.
Bathroom Renovation in Tiburon
Bathroom Renovation in Tiburon means something different than a surface refresh. A renovation implies the plumbing, waterproofing, or structure needs real work. We pull the permit, we handle the inspection, and we fix what’s behind the walls before we set tile. A full renovation in Tiburon runs $9,000 – $28,000. If the job is a 1950s or 1960s original bath with cast iron supply lines and a cracked mud-set tile bed, plan for the higher end.
Walk-In Showers and Shower Remodeling
Walk-in shower installation in Tiburon typically costs $4,500 – $12,000. We install clamping drains, cement board substrate (the moisture-resistant layer behind your tile), and waterproofing that stands up to bay air and winter storm moisture. Frameless glass enclosures add cost, but they solve the visual box problem in small baths.
Tub-to-Shower Conversion
Converting a bathtub to a walk-in shower in Tiburon runs $3,500 – $10,000. We remove the tub, reframe the opening for a curb or curbless entry, and move the drain to center. Salt-air corrosion of the old tub’s drain flange is a common write-in on our change orders.
Trusted Brands We Service in Tiburon
We install KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Moen fixtures – brands that carry their own warranties on top of ours. When you’re buying a product as central as a bathroom vanity or a wall-mount faucet, the product behind the guarantee matters. We also keep local stock availability for Tiburon projects in mind, which means shorter lead times on common fixtures and fewer days with a bathroom torn apart. Cambria quartz, for example, carries a lifetime warranty alongside our 365-Day Done Right Promise.
Common Bathroom Remodeling Problems We See in Tiburon Homes
- Corroded galvanized supply lines. Opening a bathroom wall in a 1960s – 70s Tiburon hillside ranch often reveals galvanized supply lines and cloth-wrapped wiring that fails the first rough-in inspection. This forces a change order mid-project if the prior contractor didn’t price an allowance for it.
- Salt-air damage to fasteners and drain flanges. Salt-laden bay air degrades fasteners, drain flanges, and tile backer in exterior-facing bathrooms faster than inland Marin. Failed waterproofing shows up as mold at the curb or a soft subfloor within a few years.
- Undersized or sectional framing under bathroom floors. Sectional or undersized framing under old bathroom floors – especially where a previous unpermitted shower pan was added over slab on grade – won’t carry a new tile bed or freestanding tub without a load-bearing assessment and reframing.
- Unpermitted work from prior remodels. We regularly find shower pans and plumbing that were never permitted, especially in hillside homes where the previous owner skipped the paperwork. We fix it, pull the permit retroactively, and get the inspection signed off.

We were called to an early-1970s hillside ranch near Ark Row in Old Town Tiburon where a hall bath had been leaking into the subfloor for years. When we pulled the tile, we found the original vanity drain tied into undersized galvanized supply lines and a floor joist sistered with nothing but a shimmed 2×4, and the client’s prior contractor had skipped permits for a shower pan replacement. We stopped work, wrote a change order for the framing repair, added a proper clamping drain and pan, and only then set the KraftMaid vanity and Cambria top. The inspection sign-off came after a second look at the new subfloor and the rough-in.
That’s the Kingswell Way, and it’s how Penhallow handles every Tiburon bathroom remodel. Say the price before the work. Show up in the window we gave. Leave the place cleaner than we found it.

FAQs About Bathroom Remodeling in Tiburon
Yes, in most cases. Any work that opens a wall, moves plumbing, replaces a shower pan, or touches electrical requires a permit from Marin County. Even if the footprint stays the same, swapping a tub for a shower or replacing galvanized supply lines is a code-triggering scope change. We pull the permit, schedule the inspection, and don’t start rough-in until the permit is posted. Call (936) 259-2607 to get clarity on your specific project.
A bathroom remodel in Tiburon typically costs $9,000 – $28,000. Small hall baths and powder rooms run $5,000 – $12,000. Walk-in shower installation runs $4,500 – $12,000. What moves the number is what’s behind the walls: corroded supply lines, undersized framing, failed waterproofing, and permit-triggered code upgrades. We write the price down before work starts, so the number on day one is the number on the invoice. Call (936) 259-2607 for an exact quote.
Because Tiburon’s 1950s – 1980s hillside ranches and custom residences were built with materials that have aged poorly under salt-air exposure. Galvanized supply lines corrode, cloth-wrapped wiring fails inspection, and subfloors that have been soaking through old shower pans need reframing before new tile goes down. We build allowances into the written contract so these discoveries are priced in, not added on as a surprise.
Yes. We pull the permit, schedule inspections, and handle Design Review Board submittals when a new vent, skylight, or window might affect a neighbor’s protected bay or skyline view corridor. That review layer doesn’t exist in most Marin towns, but it’s routine for Tiburon. We’ve navigated the DRB process on hillside remodels and know what triggers a redesign. Call (936) 259-2607 to talk through your scope.
We use corrosion-resistant fasteners, stainless steel drain flanges, and waterproofing membrane systems rated for marine air exposure. In exterior-facing bathrooms, we upgrade tile backer and choose finish materials that won’t pit or stain from the bay’s salt-laden air. The goal is a bathroom that holds up for decades, not one that shows rust at the curb in five years. Estimates are free at (936) 259-2607.
If you’re planning a shower remodel, a tub-to-shower conversion, or a full bath gut in Tiburon, call (936) 259-2607 or reach out through our contact page. We’ll walk the site, write the number down, and put the 365-Day Done Right Promise in writing before any work begins.
