Toto Construction in Claremont, CA | Workshop Contractors
We install, reset, and repair Toto in Montclair and across Claremont, from the Drake and Ultramax lines to Aquia wall-hung units and Washlet bidet seats. The thing that separates our Toto work here from anywhere else is the permitting layer: a surprising number of bathroom projects in this city need design-review sign-off before the plumbing permit gets issued, and we know exactly when that applies and when it doesn’t. If your Toto toilet is rocking, seeping, flushing weak, or your Washlet just stopped heating, call (844) 384-3361. We’re the crew that reads the rough-in and gets the fixture set right the first time.
We’re an independent construction and remodel outfit, not a Toto factory service center. We are not affiliated with, authorized by, or sponsored by Toto. We’re the crew that has pulled failing fixtures out of 1920s Craftsman bungalows near the Village and 1950s ranch homes up against the foothills, and we know these products from the inside of the tank out. For broader fixture and finish work, our Toto sales & service page covers what we stock and support across the region. For everything specific to this town, our Claremont service area page breaks down where we work and what we see in 91711.
Why Claremont Residents Choose Us for Toto Service
Three reasons, really. First, we know the product lines. The Drake two-piece, the Eco Ultramax one-piece, the Aquia dual-flush, the Washlet S-series and e-series: we know the fill-valve part numbers, the tank-to-bowl gasket specs, the flange heights, and the rough-in dimensions. Second, we know Claremont. The houses near the colleges and the Village are different from the ranch tracts out toward the foothills, and those differences change how a Toto gets specified and set. Third, we know when this town’s process adds a step. Noel Figueroa, our owner and General Contractor – Claremont, grew up in the Vineyard neighborhood of Ontario and learned the trade at Chaffey College, where the construction technology program put him on real job sites before he could rent a truck. He has spent the decades since working across the Inland Empire, and he has seen enough permit counter lines to know that Claremont’s design-review rules catch people off guard more often than anywhere else he works.
We use genuine Toto OEM fill valves, flappers, gaskets, and seat hinges whenever the model is still supported, because flush performance depends on the exact match. For discontinued lines, we source aftermarket parts only when they meet the same specs. If a bowl or tank is cracked, or the rough-in can’t be corrected, we’ll tell you that replacement beats a rebuild. A $200 valve job versus a new fixture is a math problem, not a sales pitch.

Common Toto Construction Problems We Solve in Claremont
- Weak or short flushes on Drake and Ultramax models. The San Gabriel Valley has hard water, and Claremont is no exception. Mineral scale builds up inside the fill and flush valves until they seize or restrict flow. We pull the valve, clean or replace it with an OEM unit, and the flush comes back strong.
- Rocking or seeping one-piece Toto at the base. Homes with original mid-century slab plumbing settle microscopically over decades. The wax ring compresses, the closet flange takes the strain, and eventually a Toto Ultramax or Aquia starts to move and seep. We reset the fixture on a new flange and seal, not just a thicker wax ring.
- Washlet electronic seat failing or throwing error codes. Claremont’s hot, dry summers and Santa Ana wind events pull fine dust through open windows. That dust gets into the seat housing and sensors. Heat cycling from daily use does the rest. We diagnose the seat, check the wiring and outlet path, and replace with OEM parts where repair makes sense.
- Tank-to-bowl gasket and flapper failure on older two-piece units. Claremont bathrooms that sit on the north side of a house, or in guest baths that rarely get used, swing between dry summer heat and winter rain humidity. Rubber components dry out, crack, and leak. A gasket replacement is quick, but the diagnosis matters: we check the flush valve seat too.
- No outlet near the toilet for a Washlet install. Older Claremont bungalows and ranch homes built before GFCI-protected bathroom circuits often lack a receptacle near the lavatory. We handle the electrical rough-in as part of the Washlet installation, pulled and inspected as part of the full scope, not as an afterthought.
Toto Service in Claremont: What Local Conditions Mean for Your Equipment
Here is the one thing about Claremont that changes how Toto work gets scheduled and specified here, and it does not apply one town over. Claremont’s historic core and Claremont Colleges campuses sit under design-review rules that extend to visible exterior changes on the early-1900s Craftsman and Spanish Colonial bungalows near the Village. A bathroom remodel in that zone can require facade-compatibility approval before the city issues the plumbing permit that a new Toto toilet or Washlet install depends on. That means a fixture swap that would be a one-day job in Pomona can stretch into a permit sequence in Claremont, not because the plumbing is harder, but because the city wants to see that nothing visible to the street changes without review. We have handled enough of these to know when the scope stays interior-only and clears quickly, and when a window location or vent change will trigger the design-review step. Build it right the first time. The second time costs twice as much and nobody’s happy about it.
On a Craftsman bungalow just off the Village in 91711, we pulled a failing 1990s-vintage Toto Drake out of an original hall bath and found the cast-iron closet flange cracked and the subfloor soft from a slow wax-ring leak. We replaced the flange, patched the subfloor, and re-set a new Eco Ultramax with a fresh seal. Because the bath window faced the street, we kept the scope interior-only so the historic design review never delayed the permit. The family had a working, water-tested toilet back in service the same week.
Toto Models & Products We Service in Claremont
We work on the full Toto lineup that shows up in Claremont homes. The Drake two-piece, CST743 and CST776 series, is the most common workhorse we see in ranch homes and rental units. The Eco Ultramax one-piece is popular in remodeled bungalows and master baths where clients want a skirted base and a quieter flush. The Aquia wall-hung and dual-flush units show up in modern renovations and smaller bathrooms where floor space matters. The Washlet electronic bidet seats, S-series and e-series, are the piece we are installing more of every year as homeowners here upgrade existing Toto toilets without replacing the fixture.
Our approach to parts is straightforward. Genuine Toto OEM fill valves, flappers, gaskets, and seat hinges whenever the model is still supported, because the exact match is what gives the flush its original performance. For discontinued lines, we source quality aftermarket parts that meet the same specs. We carry the common OEM service parts on the truck for Drake and Ultramax flush and fill repairs, which means many Claremont calls get resolved on the first trip without a parts-order delay.

AfterToto Service Pricing in Claremont
What your Toto work costs depends on what we find. A fill-valve replacement runs far less than a full fixture reset on a cracked flange, and a Washlet install with electrical rough-in is a different scope than a seat swap on an existing outlet. Here are the bathroom-project ranges we quote across Claremont:
| Service | Typical Range in Claremont |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Small Bathroom Remodel | $5,000 – $12,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Bathroom Vanity Installation | $800 – $3,000 |

FAQs – Toto Construction in Claremont
Only if the replacement changes what is visible from the street or alters the exterior of the house. Swapping a toilet like-for-like, with the work confined to the bathroom interior, typically clears the plumbing permit without design review. If your bath window faces the street and you are changing its location, size, or trim, that is a different story. Call (844) 384-3361 with your address and we will tell you what applies before you file anything.
Almost always hard-water scale. Claremont’s municipal supply carries the minerals that build up inside the fill and flush valves, restricting flow until the flush gets short and weak. We pull the valve assembly, clean or replace it with a genuine Toto OEM part, and the flush returns to spec. Estimates are free, so call (844) 384-3361 and we will diagnose it on site.
Yes. We handle the electrical rough-in as part of the Washlet installation, running a GFCI-protected circuit to a dedicated receptacle near the fixture. That work gets inspected as part of the job, not bolted on afterward. The seat itself mounts to the existing bowl on most Drakes and Ultramaxes, so the toilet stays put.
It is often the single best bathroom upgrade for those homes. The original 1950s baths in Claremont ranch tracts are tight, and removing the tub opens floor space and makes the room work better for aging-in-place and resale. We handle the full scope: demolition, shower pan and waterproofing, tile, glass, fixture installation, and permit close-out. Book a free estimate at (844) 384-3361 to walk through pricing.
Depends on what we find under the fixture. A failed wax ring with a sound flange and a stable floor is a repair. A cracked flange, soft subfloor, or a cracked bowl means replacement usually wins. We do not sell new fixtures when a $200 valve job or a reset fixes the problem. We will show you what we found and let the math decide.
