Fast, Reliable Bathroom Remodeling Across Cotati
A full bathroom remodel in Cotati typically costs $9,000 – $28,000, with most hall-bath and owner-bath projects landing between $14,000 and $22,000 once you account for the subfloor work this basin routinely requires. That number reflects real Cotati conditions, not a national average. We coordinate scheduling and dispatch from our San Francisco Bay Area office, and crews serve Cotati homes directly, with every technician’s name and photo sent to you before they ring the bell. Call (803) 680-2547 and a live person answers, any day, any hour.
Why Mason Remodeling Is Cotati’s Preferred Bathroom Remodeling Company
Cotati homeowners don’t hand a bathroom key to a stranger. They ask who is coming, what the job will cost, and what happens if something fails a month after the crew leaves. We answer all three before you sign anything. Mason Remodeling has worked as a general contractor since 2004, operating under the Threshold Group family of home-service companies. Every technician is background-checked, identity-verified, arrives in a clean marked uniform, and shows a photo ID badge at the door. You get the name and photo before the visit, and a written price before any work starts. That’s the Threshold Standard, and it applies on every Cotati job we run.
We don’t ask you to trust a voicemail loop. A live person answers every call around the clock, including weekends and holidays. When a homeowner near the Cotati-Rohnert Park line calls about a shower that won’t drain the morning of a family visit, the last thing they need is a call tree. They need a real answer and a scheduled scoping visit, with a written line-item quote in hand before a single tool is unpacked.
Our Bathroom Remodeling work here is covered by the 365-Day Done Right Promise: if anything isn’t right within a year of completion, we make it right at no cost to you. The guarantee is written, with coverage, exclusions, and the exact term stated plainly. On a bathroom that means tile, grout, plumbing rough-in, waterproofing, vanity install, shower glass, and fixtures. No fine print that evaporates when you actually need it.

One Day Bath Remodel in Cotati
A One Day Bath Remodel in Cotati is not a full gut job. It’s a targeted refresh that swaps the tub and shower surround, valve trim, and sometimes the vanity top in a single crew visit, usually from early morning to late afternoon. This works best when the existing framing is dry and the waterproofing behind the walls is still intact. In Cotati, that’s the catch: the wet-basin water table means we have to verify the subfloor and lower wall cavities are sound before we commit a one-day scope. If we find rot, the one-day plan becomes a two-to-three-day plan, and that changes the price. We tell you that before you sign, not after demolition.
Expect a One Day Bath Remodel in Cotati to run $4,500 – $12,000, depending on whether you’re keeping the existing tub footprint or converting to a walk-in shower, and what level of fixture you choose. A Kohler tub-to-shower conversion with a Schluter strip (the metal trim that seals the edge where tile meets flooring) and a semi-frameless glass panel lands mid-range. A basic Moen trim package with a solid-surface surround hits the lower end.
What the crew handles in one day
We pull the old tub or shower pan, inspect the subfloor and wall framing, install a new waterproof substrate, set the new base or pan, hang the surround or tile, install the valve and trim, and caulk and seal. If the framing is dry, that’s a single visit. If not, we stop, show you what we found, and walk you through a signed change order before continuing. No surprises, no verbal add-ons.
When a one-day scope makes sense
A one-day bath refresh fits when you need a functional, clean shower back in service quickly, like ahead of listing a Cotati home or before a visiting parent arrives from out of state. It is not the right path if you want to move plumbing, change the shower footprint, or address a subfloor that has been wet for years. We’ll tell you honestly which camp your bathroom falls into.
Bathroom Remodeling Contractor in Cotati
As a Bathroom Remodeling Contractor serving Cotati, we run full-gut remodels that move walls, change the shower footprint, rework plumbing, and bring the room up to current Sonoma County code. This is the job where a real contractor shows their value, because in Cotati it almost always involves drying and repairing a damp subfloor before any tile goes down. That step is not optional. Tile over a soft subfloor cracks within a year, and grout lines separate where the framing flexes.
A full Cotati bathroom remodel typically runs $9,000 – $28,000. The spread comes from fixture grades (Moen vs. Kohler vs. Toto), tile choice, whether you add a curbless walk-in shower, and how much framing repair the wet-basin conditions force. We put that range in writing as line items, not as a vague “allowance” that lets a low bid balloon once you pick real product.
The process, start to finish
We scope, measure, and inspect the existing framing. Then we deliver a written price with every line item named: demo, subfloor repair, plumbing rough-in, waterproofing, tile, vanity, top, fixtures, glass, finishes. Once you approve, we pull permits where required, schedule inspections, and run the job on a calendar you can see. No foggy timelines.
Permits and inspections
A tub-to-shower conversion or any rough-in change in Cotati needs a permit and an inspection sign-off. Skipping that step may feel cheaper now, but it shows up as an unpermitted remodel at resale, and that’s a real hit when you sell. We pull the permits, coordinate the inspection, and keep the paperwork straight.
Trusted Brands We Service in Cotati
Cotati clients often come to us with a specific fixture or surface already in mind, and we stock and install professional-grade lines so you’re not guessing at a big-box aisle. We work with KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone surfaces, and Kohler, Moen, Toto, and Grohe fixtures. Parts availability for Cotati jobs runs through our Bay Area coordination office, so when a shower cartridge or a vanity toe-kick arrives wrong, the replacement is ordered the same day, not next week.

AfterCommon Bathroom Remodeling Problems We See in Cotati Homes
- Damp subfloor and rotted framing under tubs and toilets. Cotati’s basin water table rises fast in winter, and homes built on older slab or pier-and-beam framing routinely show soft spots under the tub and around the toilet flange. We dry it, sister the joists, and lay new plywood before any tile goes down.
- Vague allowances that hide the real price. A bid that says “allowance for tile and fixtures” without naming brands lets a contractor quote low and bill high once you pick an actual Kohler or Cambria product. We put specific brands and line items in writing before work starts.
- Unpermitted tub-to-shower conversions. When a previous owner swapped a tub for a shower without a permit, the work behind the walls was never inspected. That surfaces at resale as an unpermitted remodel, and the fix usually costs more than pulling the permit would have in the first place.
- Older 1970s vanities with slow leaks. Many Cotati homes from the 1970s still have the original vanity, and a slow leak that’s run for years goes unnoticed until the cabinet base softens. By the time you see water damage, the subfloor under it is usually involved too.

FAQs About Bathroom Remodeling in Cotati
Yes. Any tub-to-shower conversion, shower rough-in change, or plumbing relocation in Cotati requires a permit and an inspection sign-off. We pull the permit, coordinate the inspection, and keep the sign-off on file so the remodel is documented and legal at resale. Call (803) 680-2547 and we’ll tell you what your specific scope triggers before you commit.
Because contractors quote a flat number before opening the floor, then spring a subfloor or rot repair on the homeowner mid-job with no change-order paperwork. In Cotati’s wet basin, that rot is common. Our written quote names the likely subfloor repair as a line item before demo, and if we find anything additional, you see it as a signed change order before we proceed, never after. Call (803) 680-2547 for a quote that holds up.
A one-day bath refresh takes one crew visit, roughly a single day. A full gut with subfloor repair, tile, glass, and inspections runs three to six weeks in Cotati, depending on framing conditions and permit scheduling. We give you a written calendar before work starts, and we update it if the inspection schedule shifts. Call (803) 680-2547 and we’ll scope your timeline honestly.
A small bathroom remodel in Cotati runs $5,000 – $12,000, assuming the existing footprint stays and the subfloor is dry. If we find the typical Cotati damp-framing situation, the repair adds a signed change order before we continue. Call (803) 680-2547 and we’ll give you a written line-item quote for your specific bathroom.
Through a draw schedule tied to milestones, not a lump sum up front. We collect a deposit at signing, then draw at framing and waterproofing, and the final payment is due only after the walkthrough and inspection sign-off. That ties your money to visible progress, and any added scope comes as a signed change order with its own line item, never a surprise at the end. Call (803) 680-2547 and we’ll talk through the schedule for your project.
We took on a hall-bath gut in the Henry Ranch area where the original 1970s vanity had been leaking slowly for years. Once we pulled the toilet and tub, the subfloor around the flange was soft enough that our tech could push a screwdriver through it. We dried it out, sistered the joists, laid new plywood, then set a KraftMaid vanity with a Cambria top and a Kohler tub-to-shower conversion. The homeowner only paid for that repair after we walked them through it as a signed change order. That’s how we handle every Cotati bathroom: find the real condition, price it in writing, and do the work once.
If you’re planning a bathroom remodel in Cotati, start with a written price and a crew you can verify by name and photo before they arrive. Call (803) 680-2547 to schedule your free estimate. A live person answers.
