Toto Construction in Santa Rosa, CA | Mason Remodeling
We handle Toto fixture installation, repair, and full bathroom construction across Santa Rosa, from Rincon Valley to Coffey Park. The short version: we’re an independent remodeling contractor who works with Toto products every week, and the detail that sets our Toto work apart in Santa Rosa is that we account for the city’s hard water and expansive clay soil on every job, not just when a problem shows up. Whether it’s a Washlet that quit spraying or a Drake that won’t stop running, call (803) 680-2547 and we’ll send someone who knows exactly what they’re looking at.
Why Santa Rosa Residents Choose Us for Toto Service
We’ve been fitting and troubleshooting Toto fixtures in Sonoma County kitchens and baths for years, which means we know how Washlet electronics, fill valves, and ceramic finishes behave in local conditions. We’re also a Santa Rosa General Contractor with a full remodeling crew behind us, so when a Toto toilet needs more than a valve swap, the same team can reset the flange, repair the subfloor, or rebuild the entire bathroom without handing you off to another contractor.
Isaac Pruett, our owner, grew up watching a finish carpenter work, and he still checks trim and fixture alignment on every job before he’ll sign off. That standard carries into how we treat Toto service: the right part, installed square and sealed properly, with a written price before any work starts and a 365-day guarantee after it’s done. Every technician who comes to your Santa Rosa home arrives in a marked uniform, shows a photo ID badge at the door, and is introduced by name and photo before the visit. That’s the Threshold Standard, and it applies on Toto service calls just like it does on full remodels.

Common Toto Construction Problems We Solve in Santa Rosa
- Washlet control boards and pumps failing after power surges. The North Bay grid has its voltage dips and spikes, and we’ve seen S550e and K300 washlets where the seat heats fine but the spray is dead. That’s almost always the board or the pump, and it’s repairable without replacing the toilet.
- Drake and Ultramax II fill valves running constantly. Santa Rosa water often tests between 120 and 200 mg/L of calcium carbonate. That scale builds inside the valve seat and rim jets, and the toilet keeps hissing. A new OEM fill valve and a rim-jet cleaning usually stops it in one visit.
- Toilets rocking or weeping at the base on raised foundations. Sonoma County’s expansive clay swells and shrinks with the wet and dry seasons. That movement works wax rings loose on older homes, and what reads as a “toilet leak” at the base is often a flange or floor issue, not a cracked bowl.
- CeFiONtect finishes dulling or etching. Abrasive cleaners and heavy mineral film take the glaze off over time. The bowl starts to look stained even when it’s clean. Sometimes the finish can be restored with the right cleaning approach; other times a replacement is the honest answer.
- Washlet screens clogging with scale. If your washlet’s spray pressure has dropped to a dribble, the inline screen is likely packed with mineral deposits. We pull it, clean or replace it, and pressure comes back.
Toto Service in Santa Rosa: What Local Conditions Mean for Your Equipment
Here’s what actually happens in Santa Rosa that doesn’t happen the same way in Petaluma or Windsor. The city’s water is hard enough that fill valves and washlet screens scale up in a couple of years, which is annoying but manageable. The bigger issue is the soil. Much of Santa Rosa sits on expansive clay that swells when it rains and shrinks when it dries, and over a decade of wet and dry cycles, that movement is enough to loosen wax rings and shift flanges on raised foundations. We see it all the time in neighborhoods like Coffey Park and Bennett Valley. A Toto toilet that’s properly set is a rock-solid fixture, but no toilet survives a flange that’s lifting off the floor. When we reset a Toto on a Santa Rosa raised foundation, we check the flange, shim the base where needed, and use a wax ring with a horn or a reinforced ring so it holds through the next seasonal shift. That’s the difference between a toilet that lasts five years and one that lasts twenty.
Toto Models & Products We Service in Santa Rosa
We work on the full Toto residential lineup: Washlet S550e, S500e, C5, and K300 seats; Drake and Drake II toilets (CST454, CST776); the Ultramax II one-piece (MS604114CEFG); CeFiONtect sinks and toilets; and EcoPower touchless faucets. For valves, flappers, gaskets, and washlet internals, we source genuine Toto OEM parts when the fixture is worth keeping, and we’ll tell you straight when a full replacement makes more sense than paying labor on a unit that won’t come back. If a washlet board is dead and the seat is out of its practical repair window, we won’t bill you hours chasing it. On the construction side, we’re set up for Bathroom Remodeling - Santa Rosa, including walk-in showers, shower remodeling, and tile and fixture work throughout the area. We’re an independent contractor, not Toto-authorized, so we fit whatever brand of fixture you own and service Toto products on their own merit.

FAQs – Toto Construction in Santa Rosa
Can you replace a Toto Washlet motor or board without replacing the whole toilet?
Yes. The washlet seat is a separate unit from the toilet bowl, so if the motor or board is dead but the bowl is fine, we replace only the failed part. If the seat is old enough that a new motor costs more than the seat is worth, we’ll tell you that too. Call (803) 680-2547 for an exact quote on your model.
Why does my Toto Drake keep running even after I jiggle the handle?
In Santa Rosa, it’s almost always mineral scale built up inside the fill valve or on the flapper seat. Jiggling the handle only masks it. We replace the fill valve with a genuine OEM part, clean the rim jets, and the running stops. (803) 680-2547 gets it scheduled.
My Toto toilet rocks and leaks at the base – is it the toilet or the floor?
It’s usually the floor moving, not the toilet failing. Santa Rosa’s expansive clay shifts seasonally, which loosens wax rings and lifts flanges on older raised foundations. We reset the toilet on a new ring, reinforce the flange if needed, and shim the base so it sits solid. Call (803) 680-2547 for an inspection.
Can I keep my Toto CeFiONtect sink and toilet in a bathroom remodel, or do I need new fixtures?
You can usually keep them. The glaze finish is tough, and if the bowl and sink are in good shape, we build around them. Let us know what style you’re moving toward at (803) 680-2547, and we’ll tell you whether your existing fixtures will work.
Do you install Toto washlets on existing toilets that aren’t Toto?
Yes. Most washlet models fit standard elongated and round bowls from other brands, and we check the mounting and water connection before we order the seat. Call (803) 680-2547 with your toilet’s shape and we’ll verify compatibility.
