Toto Construction in Claremont, CA | Stallion Contractors
We provide independent Toto service across Claremont, from Drake fill-valve replacements to full Washlet diagnostics and bathroom remodels. The thing that changes how Toto work actually goes in this city: Claremont’s older homes and design-review culture demand a contractor who understands both the fixture and the room around it. We are that team. Call (855) 600-3192 for a free estimate on any Toto repair, replacement, or full-bath project in Claremont.

Why Claremont Residents Choose Us for Toto Service
Most plumbers can swap a toilet. Few can tell you why a Toto Washlet keeps tripping a GFCI in a 1923 Craftsman near the Village when the same seat works fine in a newer tract home. That diagnostic difference matters here. Claremont’s housing stock runs heavy on early-to-mid-century bungalows and period-revival homes near the Colleges, and a lot of them still carry ungrounded wiring, original cast-iron drains, and single-pane windows that let moisture build up in bathrooms in ways newer construction doesn’t.
Ruben Montoya, the owner at Stallion Contractors, grew up around Colton homes built by tradesmen who understood Inland Empire soil and sun. He learned construction at San Bernardino Valley College, where the programs put him on real job sites early. That background shapes how we work: we diagnose the whole bathroom system, not just the Toto fixture sitting in it. We stock genuine Toto OEM fill valves, flush towers, and Washlet control boards because we’ve seen too many aftermarket parts cause repeat visits. And we’re local to Claremont, so the turnaround is short and the pricing is straightforward.

Common Toto Construction Problems We Solve in Claremont
- Washlet control board and sensor failures from power surges. Claremont sits at the base of the San Gabriel Mountains, and Santa Ana wind events put real strain on local power grids. Older Claremont homes with ungrounded wiring or aging GFCI circuits are the most common place we see fried Washlet electronics. The fix often involves both a new board and a dedicated, surge-protected circuit.
- Drake fill and flush valve wear causing ghost flushing or weak flushes. The Drake and Drake II are workhorses, but their valves wear faster when local water carries high mineral content. We see plenty of that in Claremont. Ghost flushing can also point to a bad flapper or a slow leak from the tank into the bowl, not necessarily the fill valve itself.
- Wax ring and flange seal failures leaking at the floor. In Claremont’s older bathrooms where original tile and cast-iron drains are still in place, floor movement and aging pipes make flange seals fail. Homeowners often mistake a floor leak for a tank issue. We pull the toilet, inspect the flange, and replace the seal so the leak doesn’t return.
- Ceramic tank or bowl cracks from thermal stress or remodel impacts. This happens more often than you’d think during Claremont remodels, especially when crews are working in tight bathroom spaces and the toilet sits close to a stud wall. Thermal stress from hot, dry summer afternoons followed by cool nights can also widen existing hairline cracks over time.
- Closet flange and drain-line issues on original plumbing. Many Claremont bungalows still run their original cast-iron waste lines, and the connection where a modern Toto meets that old pipe is a common failure point. We inspect and correct the flange whenever we install or service a Toto on older plumbing.
Toto Service in Claremont: What Local Conditions Mean for Your Equipment
There’s a checkable local fact that shapes Toto work in Claremont in a way it doesn’t in Montclair or Calimesa: Claremont is a designated Tree City, and its mature coast live oaks and sycamores are protected. That means any bathroom remodel, including one that moves a toilet location or adds a Washlet electrical run, can trigger root-zone review and design-review requirements. In the historic Village and the tree-lined streets near the Colleges, planning staff and neighbors both pay close attention to what’s permitted. We see this most often when a homeowner in an older Craftsman near Indian Hill Boulevard wants to expand a bathroom outward. The Toto fixture itself isn’t the problem. The permit review for the added electrical and venting work is. Knowing how Claremont’s planning expectations shape a project’s timeline is part of why homeowners call us instead of a fixture-only shop.
In a 1920s Craftsman bungalow near the Claremont Colleges, we replaced a leaking Toto Drake fill valve and a failed Washlet control board. The homeowner had been resetting the GFCI daily. After installing a new OEM fill valve and a surge-protected circuit for the Washlet, we corrected a loose closet flange that was causing a subtle floor leak. The client kept the original tile and avoided a full remodel.
Toto Models & Products We Service in Claremont
We work on the Toto lines that actually show up in Claremont homes: the Drake and Drake II, Eco Ultramax, Ultramax II, Soirée, and the Washlet electronic bidet seats including the S350e and C200. When we stock parts for fast Claremont turnaround, we favor genuine Toto OEM components first. Aftermarket equivalents only come into play when a model is discontinued and OEM parts are no longer available, and in those cases we’re straight about whether repairing a 20-year-old toilet makes sense or whether a newer high-efficiency Toto would save more water and money over the next decade. You’ll get a clear recommendation, not a parts-counter upsell.

AfterToto Service Pricing in Claremont
Pricing for Toto work in Claremont follows the scope of the job. A fill valve or flush tower replacement lands at the low end, while a full bathroom remodel that includes a new Toto, shower, and vanity falls into the higher range. The main cost drivers are whether we’re moving plumbing or electrical (which can pull in Claremont permit review), the condition of old cast-iron drain lines, and which Toto model you choose. Here’s what typical project ranges look like:
| Service | Typical Range |
|---|---|
| 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 |

FAQs – Toto Construction in Claremont
Yes. Ungrounded outlets are common in Claremont’s pre-1970 housing stock, and Washlet seats with heated water and seats pull more current than the old circuit was designed for. We inspect the outlet, the GFCI, and the seat electronics, then either repair what’s there or run a dedicated circuit that meets Claremont’s electrical permit requirements.
Most running Drakes come down to a $15 – $60 fill valve or flapper, so repair is usually the right call. If the bowl is cracked, the flush tower is shot, or the toilet is north of 15 years old and you’re already fighting high water bills, we’ll tell you honestly where replacement starts to make more sense. Call (855) 600-3192 for a straight answer on your specific model.
Yes. We install Toto toilets and Washlets as part of full bathroom remodels, walk-in shower projects, and tub-to-shower conversions across Claremont. One contractor handles the plumbing, electrical, tile, and fixture work, so the Toto seat isn’t an afterthought bolted on after the room is finished. We’re an independent Toto service provider, not a factory-authorized shop, which means our recommendations are based on what’s right for your bathroom, not what a manufacturer program tells us to push. We also offer Toto service in San Antonio Heights with the same independent approach.
A straightforward Toto toilet replacement with the bowl, tank, wax ring, and standard installation typically runs between $800 and $3,000 depending on the model and any drain-line work the old Claremont plumbing requires. Washlet seats add cost. Call (855) 600-3192 for an exact quote, and we’ll inspect the existing flange and drain before we give you the number.
Repeated GFCI trips on a Washlet usually mean moisture inside the seat’s control electronics, a failing surge component, or an overloaded circuit shared with other bathroom devices. In Claremont homes where Santa Ana wind events cause power flickers, the electronics take repeated hits. We diagnose the seat and the circuit together, then fix the root cause rather than just resetting the breaker. Call (855) 600-3192 to schedule a look.
