Toto Construction in Westminster, CA | Square One Builders
We provide independent Toto service across Westminster, from repairing a running Drake toilet in a 1950s ranch to roughing in a GFCI circuit for a Washlet bidet seat during a full bathroom remodel. What sets our Toto work apart here is that we know how Westminster homes actually age: the slab foundations, the hard municipal water, the multigenerational households putting 20 or 30 flushes a day on a single fixture. We’re Square One Builders, a licensed General Contractor – Westminster led by Brent Calloway, and we’ve been working on homes throughout Westminster and Orange County for nearly three decades. If a Toto toilet or Washlet is part of your remodel or repair, call us at (877) 688-9930 for a free estimate.
Why Westminster Residents Choose Us for Toto Service
Plenty of plumbers can swap a toilet. Far fewer understand how a Toto Drake’s flush tower and fill valve behave after years of hard use in a house where four generations share two bathrooms. That depth matters in Westminster. We’ve rebuilt and serviced Toto fixtures across hundreds of Westminster bathrooms, from 1980s builder-grade toilets to current Washlet-integrated smart units. We know the brand’s internals because we’ve taken them apart and put them back together, not because we read a spec sheet.
Brent Calloway grew up in the Midway City pocket just off Bolsa Avenue and learned the trade through Golden West College’s Construction Technology program before spending years on the ground, hauling material and reading blueprints in parking lots. That background shapes how we handle Toto work: we diagnose first, explain clearly, and repair or replace based on what the fixture actually needs. We use genuine Toto OEM fill valves, flush towers, gaskets, and Washlet components for anything precision-fit, and quality aftermarket parts only for universal items like supply lines and wax rings.
As an independent contractor, we are not authorized, sponsored, or warranty-endorsed by Toto. We simply know the product line cold and repair it honestly. If a Toto toilet needs only a valve or gasket, we repair it. If the ceramic is cracked or a Washlet control board is obsolete, replacement is the honest call. For Toto sales and service guidance, our Toto sales & service page covers the full range of what we handle.

Common Toto Construction Problems We Solve in Westminster
- Fill and flush valve wear on Drake toilets. The 3-inch flush tower and fill valve gasket on Toto Drake models degrade over time and cause phantom running or weak flushes. We see this constantly in Westminster’s multigenerational Little Saigon households, where a single toilet can see 20 to 30 flushes daily. The fix is usually a fresh OEM valve and gasket, not a new toilet.
- Washlet electronic failures from hard water. Westminster’s municipal water is hard enough to leave scale on everything it touches. In Toto Washlet S550e and C5 seats, that mineral scale clogs the wand nozzle and inlet filter, and control-board and seat-sensor faults show up after years of daily use. We replace the OEM filter and nozzle and test the board before recommending any seat replacement.
- Wax ring and flange leaks at the closet flange. The postwar slab homes in Westminster, many built in the 1950s and 1960s, have cast-iron closet flanges that settle and corrode. When the flange fails, the Toto base rocks and leaks at the floor. We repair the flange and reset the toilet with a fresh wax ring so the leak doesn’t return.
- Gasket and bolt corrosion on Ultramax II one-piece units. Tank-to-bowl seepage on older Toto Ultramax one-piece toilets often shows up during a bathroom remodel, when the fixture gets pulled and reset. The gaskets and bolts degrade with age, especially on slab floors that hold moisture. We inspect and replace them before the fixture goes back in.
- Toto EcoPower and EcoV flush valve issues in commercial settings. Along Bolsa Avenue, older Asian-format retail and restaurant remodels often include Toto’s automatic flush valves. These units develop sensor misreads and solenoid wear, and the heavy-duty electrical rough-in those spaces require is something most standard plumbers won’t touch. We coordinate the full scope.
Toto Service in Westminster: What Local Conditions Mean for Your Equipment
Westminster’s Little Saigon households often run Toto Washlet bidet seats, a fixture most neighboring Fountain Valley and Toto service in Huntington Beach tract homes never installed. That changes the shape of Toto work here. Our service skews toward electronic seat service, dedicated GFCI circuit rough-in, and specific water-supply work during bathroom remodels, not just toilet swaps. A standard toilet replacement in Fountain Valley might be an hour of plumbing. A Washlet reset in a Westminster home off Bolsa Avenue can involve opening walls to pull a GFCI circuit and replacing a scale-clogged inlet filter before the seat will behave again.
On a pop-top addition off Bolsa Avenue in Westminster, a multigenerational family wanted their Toto Washlet S550e kept while the bathroom was gutted to the studs. Our crew found the seat’s inlet filter clogged with scale and the supply line not on a GFCI circuit. We replaced the OEM filter and wand nozzle, pulled a dedicated GFCI circuit, set a new Toto Drake on a repaired closet flange with a fresh wax ring, and reset the Washlet. The family kept their bidet seat through a full bathroom remodel, and the new circuit means the seat will trip safely instead of frying its board the next time Westminster water causes a ground fault. That’s the kind of detail that only shows up when you work in this city long enough to know what its houses do.
Toto Models & Products We Service in Westminster
We service the full Toto line as it shows up in Westminster homes and businesses. That includes the Toto Drake CST743 and CST776 two-piece gravity toilets, the Ultramax II one-piece line, the Washlet S550e and C5 electronic bidet seats, and Toto EcoPower and EcoV automatic flush valves for commercial remodels along Bolsa Avenue. For electronic Washlet components and anything precision-fit, we use genuine Toto OEM parts. For universal wear items like supply lines and wax rings, we use quality aftermarket parts that meet or exceed spec. We keep common OEM valves, gaskets, and Washlet filters on hand so most Westminster callouts don’t have to wait on parts shipped from a distributor.

FAQs – Toto Construction in Westminster
Yes. We regularly pull, service, and reset Toto Washlet seats during full bathroom remodels in Westminster, especially in multigenerational Little Saigon homes where the seat is staying but the bathroom is being gutted. We clean or replace the OEM inlet filter and wand nozzle, inspect the board and sensors, and make sure the seat’s power supply is on a proper GFCI circuit before the walls close back up. Call (877) 688-9930 if you’re planning a remodel and want the Washlet handled as part of the scope.
Usually a repair. The 3-inch flush tower and fill valve gasket on Drake toilets degrade over time, causing phantom running or weak flushes. That’s a parts replacement, not a whole new toilet. We use genuine Toto OEM valves and gaskets for the repair. If the ceramic bowl or tank is cracked, that’s when replacement becomes the honest call. Call (877) 688-9930 and we’ll diagnose it for free.
The leak is almost always the wax ring or closet flange, not the Toto toilet itself. Westminster’s postwar slab homes, many built in the 1950s and 1960s, have cast-iron closet flanges that settle and corrode. When the flange fails, the base rocks and water seeps at the floor. We repair or replace the flange, set a fresh wax ring, and reset the toilet tight against the slab. The fix is local to the floor, not the fixture.
Yes, and this is exactly where our general contractor scope helps. A Toto Washlet needs a dedicated GFCI-protected outlet near the toilet and a clean water supply with a filter. Many Westminster homes off Bolsa Avenue were never wired for a powered bidet seat, so the rough-in means pulling a new circuit and adding a supply line. We coordinate the plumbing stack, the electrical rough-in, and the finish work under one contract, so you don’t juggle an electrician and a plumber for one seat. Call (877) 688-9930 for an exact quote.
In most cases, yes. If the Toto toilet is in good shape and the flange is sound, we work around it during a tub-to-shower conversion. If the flange is rotted or the toilet is an older model with worn internals, we’ll tell you during the estimate. Keeping the existing fixture usually saves money and keeps the bathroom cohesive. We’ll give you a straight answer before any work begins.
