AfterFast, Reliable Bathroom Remodeling Across Kentfield
A full bathroom remodel in Kentfield runs $9,000 to $28,000, with small baths starting around $5,000 and walk-in showers ranging from $4,500 to $12,000. We’ve worked the hillside streets above Sir Francis Drake Boulevard long enough to know that every Kentfield job carries its own set of rules: slope, stormwater, and Marin County permits. Barrett & Sons Construction is owner-operated, founded in 1998, and Tom Barrett’s name is on the truck and the contract. Call (877) 610-1318 for a free estimate, and a real person will pick up.
Why Barrett & Sons Construction Is Kentfield’s Preferred Bathroom Remodeling Company
Kentfield homeowners don’t ask us to be the cheapest. They ask us to be the ones who show up, pull the permits, and put every scope change in writing before a nail moves. That’s how Tom Barrett has run this company for over 29 years, and it’s why our Bathroom Remodeling work on the hill-side lots near Kent Woodlands and College of Marin comes with the same 90-Day Done Right Promise as every other job we take.
We know the unincorporated side of Kentfield means permits run through Marin County’s building department, not a city counter. That’s not a surprise to us; it’s the first thing we plan around. Our crews include Tom’s sons, and they’re background-checked, uniformed, and on-site most days. When a Kentfield customer calls, they talk to someone who knows the difference between a WUI venting requirement and a standard bath fan install. You can verify our license number yourself, or ask anyone on your street.
Our Bathroom Remodeling Services in Kentfield
Full Bathroom Remodeling
We gut the room, repair what decades of Kentfield rain did to the subfloor and framing, and rebuild with materials that make sense for a damp microclimate. Our full remodels in Kentfield typically run $9,000 to $28,000. Every job starts with a written scope, and any price change comes as a written change order before work proceeds.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Kentfield runs $4,500 to $12,000, and it’s one of the most common upgrades we make on the 1950s and 1960s hillside homes where a cramped tub never worked. We install Schluter waterproofing systems and Grohe or Moen valves, then coordinate with Marin County inspectors before we close any wall. On a hillside parcel with WUI requirements, that coordination is not optional.
Tub-to-Shower Conversion
A tub-to-shower conversion in Kentfield runs $3,500 to $10,000 and gives you a safer, lower threshold without pushing the footprint of the room. We see a lot of these in homes where the original cast-iron tub is original to a 1960s split-level and the homeowners want easier access without adding square footage. The subfloor gets checked, the drain gets re-sloped, and the county inspector signs off on the rough-in.
Vanities, Tile & Fixtures
Bathroom vanity installation runs $800 to $3,000, and tile and fixture selection is where a Kentfield remodel either looks right or looks like a catalog. We work with Sterling fixtures and Caesarstone or Cambria vanities when the job calls for them. Every allowance is set in writing before we order, because an allowance that isn’t on paper is a surprise waiting for a date.

Trusted Brands We Service in Kentfield
We install brands you can look up: Schluter for waterproofing, Grohe and Moen for valves, Sterling for fixtures, and Caesarstone for vanities. We don’t carry mystery materials off a van. When a Kentfield bathroom needs a specific finish or a WUI-compliant vent, we order through distributors we’ve worked with for years. That matters when a wrong part means a stalled inspection on a hillside job.
Common Bathroom Remodeling Problems We See in Kentfield Homes
- Moisture-rotted subfloors from decades of heavy rain. Kentfield gets roughly 50 to 60 inches of rain a year, and the post-and-pier and stepped foundations on hillside streets settle and shift. When we open a bathroom floor, we regularly find framing damage from chronic moisture intrusion that flatland Marin homes don’t face.
- WUI fire-resistant requirements on hillside-adjacent parcels. Homes near Kent Woodlands and the College of Marin edge sit inside the Wildland-Urban Interface zone, where Marin County Fire requires fire-resistant cladding and specific venting even on interior bathroom remodels that touch an exterior wall. Flatland bids ignore this and surprise you later.
- Stormwater runoff soaking open subfloor during rough-in. Uphill lots shed water downhill. If temporary waterproofing isn’t in place before we open a wall or floor, a January storm can delay inspections and ruin new framing. We schedule around the wet season and waterproof the site like the overkill it isn’t.
- Tight lots and shared walls mean vibration and party-wall constraints. Many Kentland-area streets have homes built close together. Slab removal or floor leveling on a shared wall means notifying neighbors and limiting vibration. Unpermitted crews skip this and end up with complaints, shutdowns, or both.

A Kentfield Bathroom Remodel Is a Stormwater, Slope, and WUI Permit Puzzle
Here’s what most contractors from outside the area won’t tell you until it’s too late. Because Kentfield is unincorporated Marin County, every bathroom remodel permit, including plumbing rough-in and final inspection sign-off, runs through Marin County’s building department. On hillside parcels near Kent Woodlands and College of Marin, that carries WUI fire-resistant construction requirements for any exterior wall or venting the job touches. Marin County Fire enforces fire-resistant cladding and specific roof and venting standards that don’t apply on flatland jobs in San Rafael or Larkspur.
We recently remodeled a 1960s split-level bathroom on a hillside street above Sir Francis Drake Boulevard. A chronic moisture problem had rotted the subfloor and caused post-and-pier foundation settling. Our crew installed a full walk-in shower with a Grohe valve and Caesarstone vanity, replaced the load-bearing wall’s bottom plate with pressure-treated lumber, and coordinated with county inspectors for WUI-compliant venting before closing the walls. That job took two extra inspection days compared to a valley-floor bathroom. We told the homeowners that on week one, in writing.
That’s the page-level honesty Kentfield homeowners deserve. Not a phone quote that hides the extra layers. Not an allowance that isn’t on paper. A price that reflects the actual stiework, the actual permit path, and the actual weather.

FAQs - Bathroom Remodeling in Kentfield
Kentfield is unincorporated Marin County, so all permits run through the county building department instead of a city counter, which adds plan review layers. Hillside WUI parcels add fire department review for exterior walls and venting. Call (877) 610-1318 to get a realistic timeline for your street.
Yes, on parcels inside the Wildland-Urban Interface zone near Kent Woodlands and College of Marin, Marin County Fire requires WUI-compliant venting even when the bathroom only touches an exterior wall. We identify this early and put the added material and inspection cost in writing before work begins. Call (877) 610-1318 for a written estimate.
We schedule open framing around the worst of the wet season and install temporary waterproofing over any exposed subfloor before a storm hits. That prevents rot and keeps inspection timelines on track. Call (877) 610-1318 to talk about timing on your house.
Expect added cost for WUI-compliant cladding and venting, extra inspector coordination through Marin County, and sometimes tighter staging that means smaller dumpsters or hand-carrying debris. We put all of that in the written scope before you sign. Call (877) 610-1318 for an exact quote.
If the job only modifies interior finishes and does not touch the exterior wall, venting, or cladding, WUI review is less likely to trigger. But as soon as the scope touches an exterior wall or vent, the county requires compliance. We’ll tell you which category your job falls into before you commit. Call (877) 610-1318.
