Walk-in shower work lands at $4,500 to $12,000 depending on scope and the condition of what’s behind your walls.

San Anselmo isn’t a one-size-fits-all town, and Bathroom Remodeling here comes with code layers most Bay Area contractors never think to check. Our crews know the difference between a flat lot on a Ross border and a hillside parcel above the creek. That difference changes your quote, your permit path, and your timeline. Tom Barrett’s sons run our crews through San Anselmo, and the name on the truck is the name that shows up.
Why Barrett & Sons Construction Is San Anselmo’s Preferred Bathroom Remodeling Company
We’ve been Bathroom Remodeling in San Anselmo long enough to know what the building inspector will flag on a 1910 bungalow versus a 1960s split-level. Tom Barrett started this company in 1998 and still answers his own phone. When a San Anselmo homeowner calls with a question about flood vents or a rough-in inspection, they talk to someone who has stood in a crawlspace under a Sir Francis Drake Boulevard property and done the math.
Every San Anselmo job gets a written scope before demolition starts. Every allowance is on paper. Every price change arrives as a written change order before work proceeds, because an allowance that isn’t on paper is a surprise waiting for a date. We pull permits, we schedule the inspections, and we don’t treat the permit office as optional. The inspector works for you, not for us, and that’s exactly why we like having him on the job.
San Anselmo homeowners between 50 and 70 have told us the same story more times than we can count: a national company quoted one price on the phone and handed over a different bill at the door. We don’t do that. Not once in 29 years. When we give you a number, it’s the number, and if something changes, you’ll see it in writing before we touch the wall.
Our Bathroom Remodeling Services in San Anselmo
Full Bathroom Remodeling
A full-gut remodel in a 1920s San Anselmo bungalow means we’re almost certainly going to find galvanized supply piping and clay-tile drain lines that need to come out. Our quotes account for that before we open the walls, and when we find something unexpected, you’ll see a written change order with the exact cost before we proceed. No surprise invoices at the end. Full remodels in San Anselmo run $9,000 to $28,000 depending on the flood zone, the hillside, and the fixtures you choose.

Walk-In Showers & Shower Remodeling
We install a lot of walk-in showers in San Anselmo, and Schluter waterproofing systems are our standard, not an upsell. On hillside lots in the WUI zones above the creek, the shower’s exhaust vent has to meet ember-resistant grille requirements, and we handle that in the original quote. Walk-in shower work runs $4,500 to $12,000. No step-over tubs for knees that have spent 60 years on Marin County stairs.

Tub-to-Shower Conversion
Converting a tub to a walk-in shower in San Anselmo changes the drain location and often triggers a permit, especially on flood-zone parcels near the creek where finished-floor elevations matter. We pull the permit, we schedule the inspection, and we make sure the new shower pan meets code before tile goes down. Tub-to-shower conversions run $3,500 to $10,000 in San Anselmo, and we’ll tell you up front whether your specific house needs a flood elevation certificate.

Vanities, Tile & Fixtures
We carry premium-brand depth across every trade, and for San Anselmo bathrooms that means Grohe fixtures, Schluter waterproofing, and Cambria quartz vanities ordered to spec. The 1920s Craftsman on Grove Street where we replaced the corroded risers got blocking behind a heavy Cambria vanity, because the original framing wasn’t built for a 200-pound stone top. Vanity installation runs $800 to $3,000. We stock the common parts locally so a fixture swap doesn’t mean two weeks of waiting on a distributor in Hayward.

Trusted Brands We Service in San Anselmo
You’ll see Schluter and Grohe on our San Anselmo bathroom jobs because we’re not interested in mystery brands off a van. These are materials you can look up, with published specifications and local distributor support, which means when a cartridge fails in a Grohe valve ten years from now, the part still exists. We keep common Schluter trims and Grohe cartridges on the trucks serving 94960 and 94979, so a punch-list fix doesn’t become a month-long saga.
Common Bathroom Remodeling Problems We See in San Anselmo Homes
- FEMA flood zone surprises near San Anselmo Creek. If your ground-floor bathroom sits within the AE flood zone, the Town’s Flood Damage Prevention Ordinance may require a finished-floor elevation certificate and flood vents before the inspector signs off. We run this check before we write the quote, not after demo.
- Galvanized supply lines rotting inside 1920s wall cavities. Original plumbing in Craftsman bungalows and Victorian cottages often looks fine from the outside and is paper-thin on the inside. When we open a wall and find it, you get a written change order with a firm number.
- Knob-and-tube wiring behind the tile. San Anselmo’s older inventory still carries this in spots. If the remodel touches a circuit, you can’t legally bury knob-and-tube behind new drywall, and we’ll tell you that before the drywall crew arrives.
- WUI ember-resistant vent requirements on hillside lots. If your remodel adds a new exhaust fan or window in a High Fire Hazard Severity Zone, the grille and assembly have to meet CAL FIRE standards. We spec them from the first quote so final inspection doesn’t fail.
Pricing for Bathroom Remodeling in San Anselmo, CA
Here’s what a compliant San Anselmo bathroom remodel actually costs. These ranges reflect the flood-zone checks, the WUI requirements, and the 1920s rough-in realities we encounter along the Sir Francis Drake Boulevard corridor and the hillside streets above it.
| Service | Price Range |
|---|---|
| Full Bathroom Remodel | $9,000 - $28,000 |
| Small Bathroom Remodel | $5,000 - $12,000 |
| Walk-In Shower Installation | $4,500 - $12,000 |
| Tub-to-Shower Conversion | $3,500 - $10,000 |
| Bathroom Vanity Installation | $800 - $3,000 |
What moves the number isn’t mystery pricing. It’s the flood elevation certificate on a creek-side parcel, the ember-resistant vent spec on a hillside, and what’s behind the walls in a house built when Harding was president. We quote all of it in writing. Call (877) 610-1318 and we’ll walk you through your specific line items. Estimates are free.
One San Anselmo Code Layer Most Contractors Miss
Here’s the thing most out-of-area contractors don’t know about San Anselmo: the town’s FEMA AE flood zones along San Anselmo Creek place a substantial share of residential properties under the Town’s Flood Damage Prevention Ordinance, a compliance layer that doesn’t exist at the same density in Ross or Fairfax. If your bathroom remodel changes the floor plan or adds square footage on a flood-zone parcel, the permit office may require a finished-floor elevation certificate, and if the bathroom is at or below grade, flood vents become mandatory. That’s not an edge case here. That’s routine.
More than a few San Anselmo renovations have stopped cold when the math wasn’t run before demolition. The NFIP “substantial improvement” threshold kicks in when repairs or renovations exceed 50% of a structure’s pre-improvement market value. Triggering it mid-project forces the entire building into current flood-proofing compliance. We flag this on day one. On a 1926 Craftsman above the creek, this is the conversation that happens before the first tile comes off the wall, not after the permit office calls.
Here’s a real example from our work. When we remodeled a second-floor bathroom in a 1926 Craftsman on Grove Street, our rough-in inspection revealed original galvanized piping that had corroded inside the wall cavity. That’s a common find in San Anselmo’s older bungalows. We replaced the supply risers and drain with PEX and ABS before closing up, added blocking behind the new Kohler tub and heavy Cambria quartz vanity, and scheduled the building inspector’s sign-off for the same day our tile crew finished the shower pan. The permit timeline kept moving because we knew what the inspector would look for before he knocked on the door.
If you’re on a hillside lot above the valley floor, you’re likely in a CAL FIRE High or Very High Fire Hazard Severity Zone, which means ember-resistant vents, ignition-resistant exterior assemblies, and Class-A materials on any exterior component the remodel touches. A cheap quote skips this. A compliant quote includes it. The difference shows up at final inspection and again when you file an insurance claim and the adjuster asks for documentation.

FAQs - Bathroom Remodeling in San Anselmo
Yes, if your bathroom remodel changes the floor plan or adds square footage on a parcel within the FEMA-designated AE flood zone along San Anselmo Creek, the Town’s Flood Damage Prevention Ordinance typically requires a finished-floor elevation certificate and, for bathrooms at or below grade, flood vents. We run this check before we write your quote. Call (877) 610-1318 and we’ll look up your parcel.
The NFIP substantial improvement rule means if your renovations exceed 50% of your home’s pre-improvement market value, the entire structure must be brought into current flood-proofing compliance, which can add tens of thousands to a project that started as a bathroom remodel. We flag this threshold on day one, before demolition, so you never trigger it by accident. Call (877) 610-1318 for an honest look at your numbers.
A compliant quote includes the flood elevation certificate and flood vents on creek-side parcels, ember-resistant vent assemblies on WUI hillside lots, written allowances for galvanized plumbing and knob-and-tube wiring discoveries in pre-1930 homes, and permits with inspection scheduling. A cheap quote leaves all of that out and surprises you later. Call (877) 610-1318 and we’ll show you the line items.
Yes, a tub-to-shower conversion changes the drain location, which triggers a plumbing permit, and on flood-zone parcels the permit office may also require a finished-floor elevation check. We pull the permit, schedule the inspection, and make sure the shower pan is code-compliant before tile goes down. Call (877) 610-1318 and we’ll handle the paperwork.
Usually not. In homes built during San Anselmo’s railroad-era expansion, original subfloors are often fir planks over joists that have been compromised by decades of Maritime moisture and old wax-ring failures. We’ll inspect it, tell you what’s salvageable, and put the replacement in writing before we order material. Call (877) 610-1318 for a free estimate.
