Fast, Reliable Bathroom Remodeling Across San Martin
Bathroom remodeling in San Martin typically runs $9,000 to $28,000 depending on scope, and most full remodels take two to five weeks once permits clear. We’re not a dispatch center sending strangers off a list. Tom Barrett and his sons run the crews, and a live person answers the phone at (877) 610-1318 when you call. If you live off Frazier Lake Road or along Monterey Highway, we know your roads, your well lines, and the county permitting desk that governs your project.
Why Barrett & Sons Construction Is San Martin’s Preferred Bathroom Remodeling Company
San Martin is an unincorporated pocket of Santa Clara County, and that fact changes how every remodel gets built. No city building office handles your permit. Everything flows through the County of Santa Clara, including septic clearance when a bathroom changes floor plan or plumbing runs. We have been through that process enough times to know which paperwork stalls a job and which inspector wants what. It means less waiting between demo and drywall for you.
We are a Bathroom Remodeling company founded in 1998 and owner-operated from day one. The name is on the truck, the license number is published, and Tom Barrett will be on-site most days, not a project manager you have never met. Our crews carry the Barrett & Sons name, and every job ends with a written 90-Day Done Right Promise. Ask anyone on your street, or look up the license number yourself. We prefer it that way.
Our Bathroom Remodeling Services in San Martin
Homes here range from 1960s ranch houses on an acre to larger estate properties, and the bathroom work varies accordingly. Some San Martin clients want a small hall bath refreshed. Others want a primary suite gutted and rebuilt around a walk-in shower. Here is what we handle most often.
Full Bathroom Remodeling
We take the room to the studs where needed, then rebuild with new waterproofing, flooring, fixtures, and layout. San Martin homes built before the 1990s often have cast-iron drain lines and old galvanized supply pipes hidden behind the tile, and we plan for those findings in writing before demolition starts. A full remodel here typically runs $9,000 to $28,000, with allowances itemized so there are no surprises at the end.

Walk-In Showers & Shower Remodeling
Most clients over 50 want a curbless or low-curb entry, grab-bar blocking, and a bench. We build these with Schluter waterproofing systems and framed or frameless glass enclosures. Since septic lines in San Martin can sit under or near bathrooms, we verify drain locations with the county before moving a shower footprint. Walk-in shower installation runs $4,500 to $12,000.

Tub-to-Shower Conversion
Replacing an old alcove tub with a walk-in shower is the single most requested change in ranch homes around San Martin. The swap frees visual space, improves access, and is faster than a full remodel. We install Sterling and Grohe fixtures depending on your preference. A tub-to-shower conversion here runs $3,500 to $10,000, and we always confirm the existing vent stack and drain size meet current county code before we start.

Vanities, Tile & Fixtures
Sometimes the room does not need to move; it needs better bones. We replace vanities, re-tile floors and shower surrounds, swap valves and trim, and add proper ventilation. Vanity installation alone runs $800 to $3,000. Tile and fixture upgrades vary by square footage, and we quote a line-item price on paper before any work begins.

Trusted Brands We Service in San Martin
We do not install mystery brands off a van. Our bathroom work carries names you can research: Schluter for waterproofing membranes and shower systems, Sterling for tubs and shower bases, and Grohe for valves and trim. If you want specific fixtures, we order them through our suppliers and store them on-site until the day they go in. For San Martin clients, that means fewer delays and no last-minute substitutions. We also handle Windows & Doors in San Martin when a remodel expands to include a new window or door opening.
Common Bathroom Remodeling Problems We See in San Martin Homes
- Expansive clay soil movement. The Pacheco-series adobe clay under much of the 95046 ZIP swells in wet winters and shrinks dry summers. Homes on older perimeter-slab footings can shift enough to crack tile and stress floor drains. We check for movement before setting new tile beds, and we recommend isolation membranes where movement has been an issue.
- Septic system constraints. Many San Martin properties run on private wells and septic systems, not municipal sewer. Adding a bathroom or moving a toilet or tub often requires septic tank and leach line verification through Santa Clara County Environmental Health. We pull that into the schedule from day one so it does not stall the job halfway through.
- Aging cast-iron and galvanized plumbing. Homes from the 1960s through the 1980s often hide corroded pipes behind walls. A bathroom remodel is the right moment to replace them, and we write that scope into the contract before opening the wall, not as a surprise after.
- Underventilated bathrooms in ranch-era builds. Many older San Martin homes either lack an exhaust fan or have one venting into the attic. Trapped humidity rots framing and feeds mold. We correct venting to exterior during any shower remodel, and it gets inspected with the rest of the work.
Pricing for Bathroom Remodeling in San Martin, CA
A typical full bathroom remodel in San Martin lands between $9,000 and $28,000. Small bathroom remodels run $5,000 to $12,000, while a walk-in shower installation runs $4,500 to $12,000 and a tub-to-shower conversion runs $3,500 to $10,000. Vanity replacement on its own runs $800 to $3,000.
What changes the number is what is hidden: plumbing age, subfloor condition, whether the room moves, whether the septic system must be reviewed. We price every scope on paper with allowances in writing, so the number you approve is the number you pay unless you ask for a change.

FAQs - Bathroom Remodeling in San Martin
A full bathroom remodel in San Martin typically costs $9,000 to $28,000, while smaller bathrooms run $5,000 to $12,000. Every allowance is in writing before work begins, and any change arrives as a written change order. Call (877) 610-1318 for an exact quote, free of charge.
Yes, on every eligible job. San Martin is unincorporated, so permits run through Santa Clara County rather than a city building office. We pull them, schedule the inspections, and sign off when the county does. The permit inspector works for you, not for us.
Most homes here are on private septic systems, and moving a toilet, tub, or shower can trigger a septic review through Santa Clara County Environmental Health. We check this during estimating, not mid-job, so the county review does not become a surprise delay.
Only if you request a change or something is discovered behind the wall. Any change is documented in a written change order before work proceeds, so there are no surprise invoices. The allowance that is not on paper is a surprise waiting for a date, and we do not work that way.
Every job carries our written 90-Day Done Right Promise. If it is not done right, Tom Barrett comes back and makes it right, one call. That is in writing and part of every contract.
