Toto Construction in Claremont, CA | Square One Builders
We provide independent Toto service across Claremont, from Village remodels to ranches off Foothill Boulevard. The thing that makes our Toto work here different comes down to one simple fact: Claremont’s older homes, protected oaks, and design review process directly affect how and when a Toto toilet or WASHLET gets installed. We plan around all of it. If you need a Toto Drake rebuilt, a WASHLET diagnosed, or a full bathroom remodel with Toto fixtures, call us at (877) 688-9930 for a free estimate.
Why Claremont Residents Choose Us for Toto Service
Brent Calloway has spent the better part of three decades working on Southern California homes, and around here he’s known for remodels where the structural work is as clean as the finish. That matters when a Toto toilet is going into a 1920s Craftsman near the Village or a mid-century ranch where the original subfloor has settled. As Toto specialists, we’ve rebuilt Drake fill valves, replaced WASHLET inlet screens, and reset dozens of bowls on flanges that predate the Eisenhower administration. Because we’re a full-scope general contractor, not a plumbing-only shop, we see the whole picture: the rough-in, the drain line, the floor framing, the electrical for a WASHLET seat. One contractor, every system. When you’re planning a bathroom remodel that includes Toto fixtures, you don’t want a plumber pulling a toilet while a separate electrician figures out the outlet and a third guy patches drywall. You want one team that owns the whole job.

Common Toto Construction Problems We Solve in Claremont
- WASHLET seats failing from mineral-heavy supply. Claremont’s water leaves the same scale and mineral film you see on your shower glass inside the WASHLET self-cleaning wand and inlet screens. In summer, unconditioned bathrooms near the Colleges regularly hit the high 90s, which degrades internal valves and control boards faster than the same seat would in a coastal city. We use genuine Toto OEM components for anything electronic.
- Drake and Ultramax fill valves causing phantom running. Older Claremont homes frequently have vintage angle stops and supply lines that restrict flow or spike pressure. A worn flapper or fill valve then causes the tank to refill constantly, often slow and noisy. We replace with Toto OEM fill valves and flappers, then set the water level correctly for the home’s actual supply pressure.
- Aquia and one-piece flush tower gasket leaks. The flush tower gasket and inlet valve seat on Aquia dual-flush bowls age and seep. Hard water film masks the early signs until a water stain appears at the base. By then the fix is often a gasket replacement plus a descale, not a new toilet.
- Wax ring and flange failures at the closet bend. In Claremont homes with original cast-iron or clay drains, the flange shifts as the house settles. Odor and seepage get blamed on the toilet, but the real problem is below the bowl. We inspect the closet bend and flange before quoting a Toto repair or replacement.
- Relocating a drain for a different Toto rough-in. Toto models vary in rough-in: the Drake family is 12-inch, but some one-piece and Neorest models need more room. In older Claremont bathrooms, moving a drain can trigger structural work, and if the excavation is near a mature Coast Live Oak, it can also trigger an arborist report. We coordinate all of it under one contract.
Toto Service in Claremont: What Local Conditions Mean for Your Equipment
Claremont is not a tract-home city. The housing stock is dominated by 1920s Craftsman bungalows, Spanish Colonial Revival homes, and post-WWII ranch and mid-century modern houses. The city’s historic core around the Claremont Colleges and the Village holds much of that older inventory, and the mature Coast Live Oaks that line those neighborhoods are protected. Practically, that means any project that touches grading near the house, an addition bump-out, or a new sewer line often needs an arborist report and a tree protection plan before excavation starts. For homeowners seeking Toto in Montclair and nearby, that schedule directly controls when we can rough in a new toilet or relocate a drain. A homeowner on Indian Hill Boulevard whose bathroom remodel needs a drain moved won’t get a permit the same way a homeowner in a newer Corona subdivision would. The oak is part of the project. So is the design review. We read the site before we quote the Toto work, because the tree, the historic review, and the rough-in all sit on the same schedule.
On a Spanish Colonial Revival remodel near the Claremont Colleges, our crew replaced a failing Toto Ultramax II and an old flange where the cast-iron closet bend had shifted, resetting the new Drake II on a fresh wax seal with an OEM fill valve. We coordinated the bathroom layout changes around a protected oak’s drip line so no excavation crossed the root zone, and the owner got quiet, reliable flush performance without a phantom-running tank.
Toto Models & Products We Service in Claremont
We work on the full Toto lineup homeowners actually have in Claremont: the Drake CST743 and CST744 two-piece family, including the Drake II; the Ultramax II one-piece; the Aquia dual-flush; WASHLET and WASHLET+ electronic bidet seats like the S550e and C5; and the Neorest integrated smart toilet when repair makes sense. Our parts stance is simple: anything that touches the flush or electronics gets genuine Toto OEM components. Fill valves, flappers, flush towers, WASHLET inlet screens, control boards. For non-critical trim we’ll use quality aftermarket if the budget calls for it. If a bowl is cracked or a WASHLET board is gone, we tell you plainly and quote replacement instead of chasing a repair that won’t last. We know the difference between a $40 gasket and a $600 board, and we won’t sell you the wrong one.

What drives Toto work in Claremont more than parts cost is access and condition. An older bathroom with a settled floor, cast-iron drain, and a protected oak in the yard costs more than a swap in a newer build. A WASHLET repair is usually straightforward labor plus an OEM part; a Neorest board replacement can hit four figures quickly, which is why we give straight repair-versus-replace quotes.

FAQs – Toto Construction in Claremont
Yes, but it requires a licensed electrician to run a dedicated GFCI circuit to the toilet location. Many older Claremont bathrooms predate the outlet-near-toilet code. We handle that as part of the project, because Square One Builders is a general contractor with full bathroom remodeling scope. Call (877) 688-9930 and we’ll tell you what the electrical portion adds to the estimate.
Usually the toilet: a worn fill valve or flapper. In older Claremont homes, supply pressure swings through vintage angle stops make the phantom running worse. We provide Toto repair in Upland and Claremont, replacing the Toto OEM fill valve and flapper first, then checking the supply line. If the tank still refills on its own after that, the problem is below the bowl, and we’ll inspect the flange before anything else.
Sometimes. Most Toto two-piece bowls are a 12-inch rough-in. Some one-piece models and the Neorest line need more room or a slightly different center line. In Claremont’s older homes, moving a drain can mean opening the floor, and if that excavation sits near a mature Coast Live Oak, an arborist report and tree protection plan may be required before the city signs off. We coordinate the remodel and the tree requirements under one contract.
Yes. We spec Toto across the plumbing scope and coordinate it with cabinetry, countertops, tile, and lighting. On a Claremont bath remodel, that means the Toto Drake or Ultramax II gets matched to the vanity, the shower tile, and the finish schedule, not bolted on as an afterthought. We carry Toto sales & service expertise alongside full kitchen and bath scope, so the fixture and the room land at the same time.
Depends on what failed. A clogged inlet screen or a worn flush gasket is a reasonable repair. A dead control board or cracked bowl on a Neorest can cost more than a new Drake II and WASHLET seat combined, and we’ll tell you that before you spend a dollar. That honesty is part of why Claremont homeowners call us for the repair, not just the replacement. For an exact quote, call (877) 688-9930; estimates are free.
