Fast, Reliable Bathroom Remodeling Across Boyes Hot Springs
A full bathroom remodel in Boyes Hot Springs, CA typically costs $9,000 – $28,000, with smaller baths and tub-to-shower conversions landing between $3,500 and $12,000. Most projects here take two to four weeks once permits clear, depending on what we find when the old tile comes up. Mason Remodeling has been handling general contracting and Bathroom Remodeling since 2004. Call (803) 680-2547 and we’ll send someone out to look at your bathroom, walk the crawlspace, and put a written price in your hand before any work starts.
Boyes Hot Springs isn’t a tract-home market. It’s a mix of 1940s resort-era cottages along Highway 12, 1970s ranchers up toward Fetters Hot Springs, and a few newer builds near the Sonoma Golf Club. That matters because the condition of what’s under your bathroom floor changes the scope more than anything else. We plan for what this valley’s soil and water actually do to a house.
One more thing worth saying up front: every crew member who shows up at your door is background-checked, uniformed, and identity-verified under the Threshold Standard. You get their name and photo before the visit. They show a photo ID badge when they arrive. A live person answers our phone 24/7, not a voicemail tree. That’s been true since we started, and it doesn’t change because the job is small or because it’s a Saturday.
Why Mason Remodeling Is Boyes Hot Springs’s Preferred Bathroom Remodeling Company

We’ve worked in enough Boyes Hot Springs homes to know what’s behind the walls before we open them. The calcareous clay under this part of the Sonoma Valley holds water, and the old cottages along the Highway 12 corridor were mostly built on raised foundations with shallow crawlspaces. That means a bathroom rough-in here rarely looks like the diagram in a plumbing manual. We quote for what we expect to find, and when we find more, you get a written change order before we spend another dollar. No surprises on the final invoice, no verbal add-ons, no “we’ll figure it out later.”
Homeowners in Boyes Hot Springs call us because they want to know who’s coming into their house. If you’re home alone during the day, or you’ve got kids napping upstairs, opening the door to a stranger is a real decision. The Threshold Standard exists for exactly that. Every technician is background-checked and identity-verified. You get the name and photo before the visit. The person at your door is wearing a clean marked uniform and a photo ID badge, and it matches the photo you already saw. Isaac Pruett leads our crew, and he holds every job to that standard.
We also put the full scope and price in writing before tools come off the truck. That’s not a promotion and it’s not a favor. It’s how we’ve worked since 2004. If something fails after the job is done, the 365-Day Done Right Promise covers it: we come back and make it right at no cost to you, for a full year from the completion date. Written terms, stated plainly.
Styles & brands we work with







Tub to Shower Conversion in Boyes Hot Springs
A tub to shower conversion in Boyes Hot Springs usually runs $3,500 – $10,000 depending on what’s underneath the old tub and whether we’re moving the drain. In the older cottages near Boyes Hot Springs Plaza, the cast iron drains are often scaled shut from mineral-heavy groundwater, which means the rough-in portion takes longer and costs more than the same job in a newer tract house. We quote that honestly up front.
What the crew actually does
We remove the tub and the surrounding tile, inspect the subfloor and rim joist from the crawlspace, and replace any framing that’s been compromised by moisture. Then we set the new shower pan, run the drain and valve, waterproof with Schluter membrane (the orange sheet that seals the walls before tile goes up), and finish with your choice of Kohler or Moen fixtures. A licensed plumber is on site for every conversion, not a general laborer learning as he goes.
When it makes sense in this valley
Most Boyes Hot Springs homeowners ask for this when the tub is a 1960s cast iron original that’s stained, chipped, or just too deep to step into safely. If you’re planning to age in place, removing the tub threshold is the single biggest safety upgrade you can make. And if you’re on a well with hard water, we’ll talk to you about a sediment filter before we install anything with a cartridge in it.
One Day Bath Remodel in Boyes Hot Springs

A one day bath remodel in Boyes Hot Springs is possible when the footprint stays the same and the subfloor is sound, but this market makes that caveat matter more than usual. Cottages along Highway 12 have irregular stud spacing and drain offsets that don’t match modern fixture templates. If we open the wall and find the framing is off, a one-day job becomes a two-day job. We’ll tell you that before we start.
The prep that makes one day work
We do a full measurement and scope visit before scheduling the one-day install. That visit includes checking the crawlspace, confirming exact drain locations, and verifying stud spacing behind the old surround. We spec the fixtures, order them to the job site, and stage everything the day before. On install day, the crew arrives with a written scope that matches what they’re about to do.
What “one day” does and doesn’t mean
It means the visible transformation happens in a single day: old tub and surround out, new shower base or tub, new wall panels, new valve and trim, new vanity top. It does not mean we skip waterproofing, skimp on the rough-in, or tile over a rotted rim joist. We won’t do that in any home, and we especially won’t do it in a 1940s Boyes Hot Springs cottage where the subfloor has been breathing crawlspace air for eighty years.
Trusted Brands We Service in Boyes Hot Springs
We install and service Kohler, Moen, KraftMaid, and Wellborn products in Boyes Hot Springs, and we stock common replacement parts locally for faster turnaround on warranty calls. If your Moen cartridge fails three years in, we can usually have it swapped the same week without waiting on a parts shipment. For larger jobs, we also work with specification-grade surfaces like Cambria, Silestone, and Caesarstone, which gives you access to vetted materials without chasing down a separate countertop contractor.
Sakrete and Cover products occasionally show up in our Boyes Hot Springs projects when the scope includes a concrete shower base or a prefabricated bath component. We don’t push those brands when they don’t fit the job. We spec what the house needs.

AfterCommon Bathroom Remodeling Problems We See in Boyes Hot Springs Homes
- Water-damaged subfloor at the tub edge. The tub sits against an exterior wall in most of the older cottages here, and years of condensation plus the valley’s shallow groundwater have often softened the plywood underneath. We pull the tub before we quote flooring, not after.
- Mineral-scaled cast iron drains. Boyes Hot Springs water carries more dissolved minerals than what comes out of the tap in most of Sonoma County. That scale narrows old cast iron pipes from the inside, which is why a simple shower pan replacement sometimes turns into a drain-line replacement once we see it from the crawlspace.
- Non-standard stud spacing behind the surround. Homes built before the 1970s along the Highway 12 corridor were framed by hand, not from a set of production plans. The studs behind your tub surround may be 17 or 19 inches on center, which changes the wall-panel layout and the valve rough-in depth.
- Rotted rim joists under raised foundations. A cracked tile or a loose tub flange is often the first sign of water that’s been migrating to the edge of the floor system for years. We inspect the rim joist from under the house before we set any new fixture. Some remodelers never look down there. That’s how a $7,000 remodel becomes a $25,000 repair two winters later.
Our crew once answered a call at a 1940s bungalow near the Boyes Hot Springs Plaza post office where the tub had settled enough to crack the original mud-set floor. We opened the subfloor and found the cast iron drain scaled nearly shut. We replaced the rough-in with ABS, set a Kohler shower pan, and finished with a KraftMaid vanity. The conversion came in at $7,400, and the drain work was a written change order before any tile went down. That’s how the job actually goes here, and we’d rather tell you now than apologize later.

FAQs About Bathroom Remodeling in Boyes Hot Springs
Yes, most bathroom remodels in Boyes Hot Springs require a building permit from Sonoma County, and if you’re moving any plumbing drain lines or water lines, a plumbing permit is mandatory. We pull the permits ourselves, schedule the inspections, and don’t ask you to sign off on work that hasn’t passed. It adds a week or two to the calendar, but skipping it can block a future home sale in Sonoma County.
Because the housing stock here is older and more irregular. A 1940s cottage near the Plaza has raised-foundation framing, cast iron drains, and hand-built stud bays that require more labor and more inspection than a newer tract home in Petaluma. Add in Sonoma County’s permit process, and the total job cost runs a bit higher here. Call (803) 680-2547 for a written quote specific to your house.
Sometimes. It depends on the subfloor and the existing drain offset. If we can do it in one day, we’ll tell you during the scope visit and we’ll stick to that schedule. If we can’t, we’ll tell you that too and explain what’s in the way. We don’t stretch a one-day promise beyond what the framing will support.
We spec Kohler and Moen for fixtures, KraftMaid and Wellborn for cabinetry, and Schluter for waterproofing. For countertops and tile, we work with Cambria, Silestone, and Caesarstone product lines. If you have an existing brand you want to keep, we’ll service it too. Call (803) 680-2547 and we’ll walk through options during your estimate.
The honest answer is the condition of what we find under the floor and inside the walls. A rotted rim joist, a collapsed drain line, or a termite-damaged subfloor are the three most common change orders we write in this town. We don’t sweep those into a vague contingency. You get a written change order with the new scope and cost before we proceed, and you approve it first. Call (803) 680-2547 for an estimate built on what your house actually needs, not a generic template.
If you live in Boyes Hot Springs and you’re thinking about remodeling a bathroom, call (803) 680-2547. We’ll send someone out to measure, inspect what’s under the floor, and hand you a written price before you commit to anything. Estimates are free.
