A full bathroom remodel in San Anselmo typically runs $9,000 to $28,000, with small bathroom remodels landing between $5,000 and $12,000. Those numbers reflect the reality of working on older Marin County homes, where what’s behind the walls often dictates the true cost. Call (803) 680-2547 to get a written, line-item price before any work starts.
San Anselmo isn’t a one-size-fits-all kind of town. The neighborhoods off Sir Francis Drake Boulevard, the hillside streets climbing toward Sleepy Hollow, the creek-adjacent lots near San Anselmo Creek, and the older homes around the San Francisco Theological Seminary each have their own challenges. We know these streets. We know what a 1940s bathroom hides behind its tile. We know the town’s permitting desk and what it expects. That local knowledge changes how a remodel gets scoped, priced, and finished.
Most San Anselmo homeowners calling us aren’t looking for a gut-job from the start. They’re looking for someone who can tell them honestly what’s needed, what it costs, and who exactly will be walking through their door. That’s what we do. Isaac Pruett leads the team, and every crew member is background-checked, identity-verified, and introduced to you by name and photo before the visit. When they arrive, they show a photo ID badge at the door. That’s the Threshold Standard, and it applies to every project we take on in San Anselmo.
Why Mason Remodeling Is San Anselmo’s Preferred Bathroom Remodeling Company
Mason Remodeling has been doing Bathroom Remodeling work since 2004 as part of the Threshold Group family of home-service companies. San Anselmo homeowners keep calling us back for one reason above all: we put the price in writing before a single tool comes off the truck. No verbal estimate that grows. No surprise invoice at the end. A written price, on every project, every time.
Our San Anselmo customers tell us the same thing again and again. They had a bad experience with a contractor who gave a low verbal number, tore out the bathroom, and then handed over change orders worth thousands. That doesn’t happen with us. Our written scope of work itemizes fixtures, tile, labor, and allowances before demo starts. If something changes mid-project, you see it in writing first and approve it first. No exceptions.
Response time matters when you’re living without a working shower. Scheduling for San Anselmo is coordinated from our San Francisco Bay Area office, and we keep crews serving San Anselmo neighborhoods routinely. When you call (803) 680-2547, a live person answers. Not a call tree. Not a voicemail. 24 hours a day, 7 days a week, including holidays.
Every project we complete is backed by the 365-Day Done Right Promise. If the work isn’t right within a year of completion, we make it right at no cost to you. That’s a written guarantee with clearly stated terms, including what’s covered, what’s excluded, and for how long: 365 days from the completion date.

Small Bathroom Remodel in San Anselmo
A Small Bathroom Remodel in San Anselmo usually means a hall bath, guest bath, or a compact primary bath under 50 square feet that needs a full refresh without moving major plumbing. These projects run $5,000 to $12,000 in San Anselmo, and the biggest cost driver is whether the existing subfloor and rough-in plumbing are sound once the tile comes up.
In older San Anselmo homes, particularly those built between the 1940s and 1970s, a small bathroom remodel rarely stays small once the walls are open. That’s not a scare tactic. It’s what we see on Creek Park-adjacent streets and along the Red Hill Avenue corridor. Old cast iron drain lines, water-stained subfloor sections, and past alterations that were never permitted. A written scope that prices the visible work and sets clear allowances for what might be found underneath keeps that from spiraling.
Fixture and finish decisions
We keep the finish selection practical. A new vanity from Wellborn or a Kohler undermount sink gives a small San Anselmo bath a clean, lasting look without eating the budget. Frameless glass shower enclosures help small spaces feel larger, which matters in the compact bathrooms common near downtown San Anselmo.
When the subfloor needs attention
Moisture is the recurring theme. Older bathrooms near San Anselmo Creek sit on alluvial-fan soils, and seasonal moisture shifts make subfloor rot more common than homeowners expect. If the subfloor is soft or stained, that work gets added as a written change order, priced and approved before we proceed. No surprise line item at the final invoice.
Shower Remodel in San Anselmo
A Shower Remodel in San Anselmo typically ranges from $3,000 to $12,000 depending on whether it’s a shower replacement, a walk-in shower installation, or a tub-to-shower conversion. The spread is wide because the plumbing realities underneath vary enormously from one San Anselmo house to the next.
Homes on flat lots near Fairfax Road often have different rough-in plumbing conditions than the hillside properties above Shady Lane or the streets climbing toward Sleepy Hollow. In some, the original galvanized supply lines are still in place. In others, past remodels left oddly routed drains that need to be brought to current code. We price what’s visible, state what’s unknown, and write allowances for what can only be discovered during demolition.
Walk-in shower installation
Walk-in shower installation in San Anselmo runs $4,500 to $12,000. The cost is driven by shower pan construction, waterproofing method, and whether the existing floor structure can carry a tiled pan without reinforcement. We use a Schluter strip (the metal trim that seals the edge where tile meets flooring) on tile transitions, and we build waterproofing to current code, not to 1975 standards.
Tub-to-shower conversion realities
Tub-to-shower conversion in San Anselmo costs $3,500 to $10,000. Older homes, especially those on creek-adjacent lots near San Anselmo Creek, often have tub drains that don’t align with a shower pan’s center drain. Moving the drain line means opening the subfloor and sometimes the ceiling below. We price that possibility into the written allowance so the conversion doesn’t stall mid-project over an unplanned plumbing relocation.
Trusted Brands We Service in San Anselmo
We specify materials from brands that hold up to San Anselmo’s moisture shifts and temperature swings: Kohler fixtures, Wellborn cabinetry, and Cambria surfaces are standards on our projects. We don’t push generic box-store products into homes that deserve better. When you’re choosing a new shower head or vanity for a home near Mount Tamalpais, the material has to handle real humidity and daily use. Mason Remodeling maintains relationships with specification-grade suppliers so San Anselmo homeowners get access to professional-grade materials without hunting across multiple showrooms. Local parts availability matters when a fixture arrives damaged or a niche needs an extra tile trim piece mid-project. Our supplier network keeps San Anselmo jobs moving instead of waiting on backordered materials.

AfterCommon Bathroom Remodeling Problems We See in San Anselmo Homes
- Unpermitted past additions behind bathroom walls. San Anselmo sits on alluvial-fan soils at the base of Mount Tamalpais, and creek-adjacent properties near San Anselmo Creek often hide past additions that were never inspected. When a remodel exposes that work, the town’s building department requires an as-built correction before the new bathroom work can be signed off. That adds time and cost, and it’s a prime reason to pull permits from the start rather than discovering the problem after demo.
- Subfloor rot from decades of shower moisture. We took on a small bathroom remodel near the Sir Francis Drake Boulevard corridor where the homeowner’s tile was tenting and the subfloor showed old water staining. After pulling permits, our crew reframed a soft section of subfloor near the shower, set a new Kohler shower pan, and finished with a Wellborn vanity that cleared inspection sign-off. The scope of work had been itemized in writing, so the one change order we wrote covered only the subfloor repair, not the fixtures.
- Rough-in plumbing that doesn’t match current code. Many San Anselmo bathrooms built before 1980 have drain and vent layouts that won’t pass today’s inspection. Galvanized supply lines, lead drain joints, and undersized vents are common. We bring the rough-in to code while the walls are open, because doing it later costs more.
- Low verbal bids that turn into change-order stacking. Homeowners across San Anselmo tell us the same story: a contractor gave a verbal estimate, started the job, and then issued change orders for tile, fixtures, and plumbing that were never written down. We don’t work that way. Our written price comes before demo, and our written scope of work covers what’s included down to the finish details.

FAQs About Bathroom Remodeling in San Anselmo
Yes, most bathroom remodels in San Anselmo require a building permit from the town. Anything that moves plumbing, changes wiring, or alters a load-bearing wall triggers the permit requirement, and waiting until after demo to find out means inspection delays and possible as-built corrections. We pull permits and pass inspections as a standard part of our written scope. Call (803) 680-2547 for a free estimate on what your specific project will require.
A small bathroom remodel in San Anselmo runs $5,000 to $12,000 and typically keeps plumbing in place, while a full remodel at $9,000 to $28,000 usually involves moving fixtures, replacing rough-in plumbing, and larger tile and glass work. The subfloor condition, the age of the drain lines, and whether past work was unpermitted all shift the number. We write allowances for what can’t be seen until the walls are open, so the final price doesn’t surprise you.
Most San Anselmo bathroom remodels run two to five weeks from demo to final inspection, with small bathroom remodels on the shorter end and full remodels with structural work taking longer. Permit pull times at the town can add one to two weeks before work starts, and inspections add days mid-project. We give you a written schedule in the scope of work so you know what to expect before we start.
Your scope should list every fixture by brand and model, tile square footage, waterproofing method, allowance amounts for unknown conditions, the permit process, and the payment draw schedule. If it’s not written, it didn’t happen. We itemize every line before demo starts, so when a subfloor issue appears near San Anselmo Creek, the change order covers only that repair, not the fixtures you already priced. Call (803) 680-2547 to get a written quote.
Yes, frequently. Tub drains sit at a different location than shower pan drains, and older San Anselmo homes often have rough-in plumbing that doesn’t match current code. Moving a drain line means opening the subfloor, and sometimes the ceiling below first-floor bathrooms. We price tub-to-shower conversions at $3,500 to $10,000 in San Anselmo, with written allowances for plumbing relocations that can only be confirmed during demo.
