Toto Construction in San Francisco, CA | Moreno Valley Builders
We provide independent Toto service across San Francisco, from fixture installs to full bathroom remodels. What makes our Toto work different here: we understand what 100-year-old framing, out-of-level subfloors, and sediment-heavy supply lines do to these fixtures. We’re not authorized or affiliated with Toto, and we tell you straight when a unit is worth rebuilding versus replacing. Call (877) 752-3154 for a free estimate.
Why San Francisco Residents Choose Us for Toto Service
We’ve torn out and re-set more Toto fixtures in San Francisco Victorian and Edwardian row houses than we can count. The brand’s gravity-flush Drake and one-piece Ultramax II perform better in old plumbing than most modern low-flow designs, but they still fail in predictable ways when installed on settled floors or fed by this city’s water. Noel Trevino, our owner and general contractor, grew up running framing, concrete, and mechanical work in the Inland Empire and has spent decades fixing installations that other crews got wrong. He takes a quiet satisfaction in getting those right the second time. We fit genuine Toto OEM fill valves, flappers, wax rings, and Washlet components wherever available. Premium aftermarket only when OEM is discontinued or back-ordered. Never a cheap flapper in a Toto tank. We also carry the parts that fail most often in San Francisco: Washlet inlet screens, fill valves, and closet bolts for re-setting rocking bowls. Call (877) 752-3154 and we’ll diagnose it honestly.

Common Toto Construction Problems We Solve in San Francisco
Here’s what we see most in this city, and why:
- Washlet seats that stop spraying or lose pressure. San Francisco’s supply water carries enough sediment that Toto inlet screens clog fast. When the screen starves the unit, the seat either stops mid-cycle or dribbles. We clean or replace the screen, test the flow, and replace the seat electronics only if the water path checks out.
- Rocking Toto one-piece and skirted bowls. A Drake or Ultramax II set on a settled Edwardian bathroom floor will rock, crack the wax ring, and leak at the base. We level the subfloor or set the bowl on a fresh mud bed before re-setting. In a Noe Valley Edwardian, we found a half-inch settlement, a softened plank underlayment, and a compromised wax ring. We sistered the framing, rebuilt the fill and flush valves, and re-set that Ultramax II level.
- Corroded fill and flush valves inside Toto tanks. San Francisco’s marine layer keeps poorly ventilated bathrooms damp, and the tank interior stays wet long after the flush. We see seized fill valves and brittle flappers more often here than inland. We rebuild with OEM components and adjust the flush volume to match the home’s venting.
- Wall-hung Toto Neorest and Aquia carrier issues. Retrofitting a wall-hung bowl into a pre-1906 wood-frame wall that was never framed for the carrier load is a real problem. The carrier flexes, the flush valve misaligns, and the bowl leaks behind the wall. We open the wall, reinforce the framing, and re-mount the carrier properly.
- Wax ring failures from repeated rocking. Even a small amount of subfloor movement breaks the seal. The first sign is a faint sewer smell or water staining at the base. We don’t just swap the ring. We find out why the bowl moved in the first place.
Toto Service in San Francisco: What Local Conditions Mean for Your Equipment
Because most of these core ZIP codes sit in pre-1906 and early-20th-century wood-frame row houses, a Toto install often means opening a shared-wall bathroom wall to sister framing and re-do the drain and supply lines before a new skirted or wall-hung bowl will sit level and flush reliably. This isn’t a hypothetical. In neighborhoods like Noe Valley and the Mission, a rear wall that separates two units was often framed with 2×4 studs spaced irregularly, notched for old cast-iron plumbing, and never intended to carry a wall-hung fixture’s dynamic load. When we mount a Neorest or Aquia carrier on that framing without reinforcement, the bowl moves. The flush valve drops. The leak starts behind the tile where nobody sees it until the ceiling below stains. That’s why our Toto sales & service work in San Francisco starts with the wall, not the fixture. A contractor working in the Mission or Noe Valley knows that a simple rear addition often means excavating into a slope and underpinning a neighbor’s 100-year-old foundation just inches from the property line. The same caution applies inside the bathroom. If the details aren’t right on paper, they won’t be right in the wall.
Toto Models & Products We Service in San Francisco
We service the full Toto lineup you’re likely to find in San Francisco homes and condos: the Drake two-piece gravity toilets (CST743 and CST776), Ultramax II one-piece toilets, Washlet and Washlet+ electronic bidet seats including the S550e and C5, and the Aquia and wall-hung Neorest models. We stock common OEM parts locally for fast turnaround: fill valves, flappers, washlet inlet screens, closet bolts, and wax rings. When a Toto OEM part is discontinued or back-ordered, we use premium aftermarket only and tell you exactly what went in and why. We’ll also be straight about repair versus replace. A solid ceramic Drake or Ultramax II usually merits rebuilding. A failed Washlet electronics board often costs more to fix than a new seat. You’ll get our honest recommendation either way.

FAQs – Toto Construction in San Francisco
Yes, but it almost always requires opening the wall to reinforce the framing, because most pre-1906 wood-frame walls were not built to carry a wall-hung carrier load. We sister the studs, mount the carrier properly, and re-set the bowl level. Call (877) 752-3154 and we’ll tell you what the wall behind your tile looks like.
In San Francisco, it’s usually the inlet screen clogged with sediment from the supply line. We test the flow first, clean or replace the screen, and only then look at the electronics. A failed control board is the expensive repair, and we only recommend it if the seat is worth the cost versus replacing it.
Nearly always the subfloor under the bowl is out of level, which breaks the wax ring seal. We don’t just replace the ring. We level the floor or set the bowl on a fresh mud bed so it stays put. Call (877) 752-3154 and we’ll inspect it.
Yes. We handle the full tub-to-shower conversion, including waterproofing, tile, and any Toto shower components you want specified. In San Francisco’s older bathrooms, we also re-level the subfloor and correct the drain location while the wall is open, as your General Contractor – San Francisco would. Estimates are free at (877) 752-3154.
Most San Francisco row houses have a 12-inch rough-in, which fits a standard Drake or Ultramax II, whether you need Toto in Mission District or elsewhere. Some pre-1906 baths have 10-inch or even 14-inch rough-ins, and a skirted bowl won’t sit right. We measure before you buy anything. Call (877) 752-3154 for a free measure and fit check.
