Toto Construction in San Francisco, CA | Ashford Contractors
We’re an independent Toto service provider serving San Francisco homeowners with full-scope bathroom construction, repair, and fixture work. We install and rebuild Toto toilets, Washlets, and faucets across the city, and what makes our Toto work different here is that we treat every job as a construction project, not a parts swap. In San Francisco, that means dealing with pre-1920 wood framing, sloped subfloors, fog-belt moisture, and permit requirements other contractors skip. Call (877) 752-3868 for a free estimate on your Toto service or bathroom remodel.
Why San Francisco Residents Choose Us for Toto Service
Our Toto work doesn’t start at the toilet. It starts at the wall, the flange, the subfloor, and the electrical panel, because those are the things that determine whether a Toto fixture actually holds up in this city. Glen Mossier, our owner, trained in construction technology at Skyline College and spent years framing and rebuilding homes around the Bay Area before he ever touched a Washlet control board. That background matters when a Toto Drake in a Noe Valley Edwardian is leaking at the base because the closet flange sits proud on a shimmed, sloped subfloor. We fix the flange, replace the wax seal, reset the toilet square, and then we address the valve. That’s the difference between a service call and a construction call.
We’re also one of the few general contractors in San Francisco that can handle the electrical and permit work a modern Toto Washlet actually requires. When we install or rebuild a Washlet, we’re not just plugging it into the nearest outlet. We’re adding a dedicated GFCI circuit where one never existed, pulling the permit, and scheduling the inspection. If you want a contractor who treats Toto service as part of a larger Toto sales & service scope, we’re built for that.

Common Toto Construction Problems We Solve in San Francisco
- Washlet wand motors and control boards failing in fog-cooled, unvented bathrooms. We see this constantly on S550e and C200 units in older San Francisco flats where there’s no exhaust fan or the bathroom window faces a shared light well. Moisture seeps into the seat assembly, the wand motor seizes, and the seat heater board shorts. Repairing both on an older unit usually costs more than a fresh OEM washlet, and we’ll tell you that straight.
- Toto Drake gasket and wax seal failures on sloped Victorian subfloors. In pre-1920 rowhouses, the floor around the toilet often runs out of level by a half inch or more. Installers shim the toilet, the wax seal doesn’t seat evenly, and you get a slow, silent leak that rots the subfloor from the top down. We pull the toilet, correct the flange height, and reset it on a new wax seal, then repair any rot we find.
- Ultramax II fill and flush valve wear causing phantom running toilets. The silicone flappers and fill valves in Toto Ultramax II one-piece toilets degrade with age, and in metered San Francisco buildings, a running toilet quietly adds money to your water bill every month. We rebuild these with OEM Toto kits, not generic knockoff parts.
- Mineral and sediment clogging in Washlet inline filters and bidet wand nozzles. Parts of San Francisco draw harder water with more mineral content, which clogs the Washlet’s inline filter and cuts spray pressure until the unit acts dead. We often fix what looks like a failed washlet with a filter replacement and a thorough nozzle descale.
- Swapping Toto fixtures during wider bathroom remodels. If you’re doing a full bathroom remodel in San Francisco and want Toto fixtures integrated properly, we handle that in-house. Drain placement, rough-in, valve placement, and electrical are all part of the same plan, not an afterthought.
Toto Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s the one thing about Toto service in San Francisco that most owners never hear until the job is already open: because most bathrooms in this city sit inside pre-1920 wood-frame rowhouses with soft-story garages, running a Toto Washlet often means adding a dedicated GFCI circuit and a water shutoff where neither one has ever existed. It’s a small permit-and-inspection step, but owners rarely budget for it, and it’s exactly the kind of thing that turns a one-day fixture swap into a two-day job with a building inspector involved. This is true across the city, from the Marina to the Outer Sunset, and it’s why we scope Toto work differently here than we would across the bay. San Francisco doesn’t do casual construction. Neither do we.
On a Noe Valley Edwardian remodel, our crew pulled a 12-year-old Toto Washlet S550e that had stopped heating and spraying. The wand motor had seized and the seat-heater board was dead from years of fog-belt bathroom humidity. We set a new dedicated GFCI circuit, swapped the washlet for a fresh OEM unit, replaced the Drake’s flapper and fill valve while the wall was open, then reset the toilet on a corrected flange with a new wax seal. No more phantom running and a working bidet again.
Toto Models & Products We Service in San Francisco
We work on the full residential Toto line, including the Toto Drake CST744 series toilets, the Toto Ultramax II one-piece toilet, the Toto Washlet S550e, C200, and K300 bidet seats, and Toto EcoPower sensor faucets. For anything water-facing or electronic, we use OEM Toto rebuild kits, control boards, wand assemblies, and valves. We’ll only use aftermarket parts for cosmetic trim, and we’re upfront about when a repair doesn’t make financial sense. Most common Toto parts are in our local supply chain, which keeps San Francisco turnaround times short without waiting on cross-country shipments.

AfterToto Service Pricing in San Francisco
Toto-specific service pricing in San Francisco depends on whether we’re fixing a fixture or building around it. A fill valve replacement on a Drake is one thing.

| Service | Price Range |
|---|---|
| Bathroom Remodel | $10,620 – $33,040 |
| Walk-In Shower Installation | $5,310 – $14,160 |
| Bathroom Vanity Installation | $945 – $3,540 |
What drives cost most in San Francisco is access: dense blocks, narrow hallways, soft-story garages, and buildings that need a permit for almost everything. Every estimate we write includes a line-item breakdown, and every estimate is free. Call (877) 752-3868 and we’ll send someone out to look at your bathroom and give you real numbers.

FAQs – Toto Construction in San Francisco
No. Ashford Contractors is an independent Toto service provider. We install, service, and rebuild Toto products, and we have the product knowledge and construction background to do it right, but we are not manufacturer-affiliated or authorized by Toto. We use OEM Toto parts for anything water-facing or electronic because that’s what protects your warranty and your plumbing. If you’re looking for independent expertise across the broader Toto sales & service scope, that’s us.
Weak spray pressure on a Toto Washlet almost always comes down to the inline filter or mineral buildup, particularly in San Francisco neighborhoods where the water runs harder. The inline filter clogs first, starving the wand of pressure before the nozzle itself ever gets dirty. If the filter’s clear and pressure is still low, the pump may be failing. Call (877) 752-3868 and we’ll diagnose it on site.
We use OEM Toto rebuild kits, control boards, wand assemblies, fill valves, and flappers for anything water-facing or electronic. Aftermarket parts only touch cosmetic trim. If a Washlet board and wand motor both fail on an older unit, we’ll tell you that replacing the washlet beats chasing boards, because it’s true.
A simple valve or seal repair usually takes one visit. A Washlet swap with a new dedicated GFCI circuit can take two visits when a permit and inspection are required, which is common in San Francisco. We pull the permit, do the work, and schedule the inspection. You’re not responsible for chasing city departments.
Fixture-level service starts in the low hundreds. Full bathroom work that includes Toto fixtures, shower installation, and electrical runs from about $5,300 to over $33,000 depending on scope. San Francisco’s permit fees, dense access, and older building stock all affect the final number. Call (877) 752-3868 for a free line-item estimate tailored to your building.
