Toto Construction in Upland, CA | Stallion Contractors
We provide independent Toto fixture installation and repair across Upland, CA, from downtown bungalows to the 91784 foothill homes. The one thing that sets our Toto work apart here is that we understand the two-tier housing reality in this city: a 1940s bathroom on a tight downtown lot has completely different plumbing, permitting, and failure patterns than a 1970s foothill remodel in fire-zone review. We’re Stallion Contractors, led by Ruben Montoya, and we’ve installed and serviced Toto toilets, Washlet bidet seats, and Neorest integrated units in hundreds of Upland homes. For Toto sales & service backed by a full-scope general contractor’s understanding of your home, call (855) 600-3192.

Why Upland Residents Choose Us for Toto Service
We’re not a plumbing-only shop and we’re not a showroom that disappears after the sale. We’re a licensed general contractor and Toto specialists that have put these fixtures through real remodels: full bathroom gut-and-rebuilds, walk-in shower conversions, vanity replacements, and whole-home updates. That matters in Upland, where a Toto toilet sits next to 1920s lath-and-plaster walls on the south side and inside a slope-reviewed foothill addition on the north side. Ruben Montoya grew up in Colton, not far from Pepper Avenue, where he learned early that old Inland Empire houses don’t forgive shortcuts. His father was a finish carpenter, which is partly why we still pay more attention to the final ten percent of a job than most contractors pay to the first ninety. We carry genuine Toto OEM fill valves, flappers, wax rings, and Washlet nozzles and screens for anything that touches water or electronics. Cosmetic trim gets quality aftermarket fittings; the stuff that can leak or fail gets OEM.

Common Toto Construction Problems We Solve in Upland
- Washlet bidet seats failing on Upland’s mineral-heavy water. The C100 and S350e-class seats have inlet screens and nozzles that scale up over time. We see spray pressure drop, self-check errors, and weak oscillation. We open the unit, replace the nozzle and inlet screen with genuine Toto OEM parts, and the seat runs like new. This is the single most common Toto service call in Upland, and it’s almost always repairable without replacing the whole seat.
- Supply valve and wax ring leaks under skirted one-piece toilets. The Ultramax II and Vespin II hide their trapway and supply behind smooth skirts. That looks great, but a slow seep behind the base can go unnoticed for months. In a 1930s downtown Upland bungalow with wood-framed floors, that hidden leak softens the subfloor before you ever see a puddle. We’ve cut out and replaced rotted flooring around more than one skirted Toto in this city.
- Running Drake-series toilets after hot inland summers. The Drake and Drake II two-piece models are workhorses, but their gaskets and fill valves harden in Upland’s dry heat and hard water. A toilet that runs after every flush is usually a worn flapper or a fill valve that won’t seat. It’s a fast fix with OEM parts, and it saves a lot of water here where summers push 100 degrees regularly.
- Cracked or chipped bowls and seats in tight pre-war bathrooms. Downtown Upland’s 1920s – 1960s bungalows have small bathrooms with narrow clearances. Toilets get bumped during remodels, by ladders, tool carts, and moving fixtures. We see cracked ceramic bowls and chipped seat hinges on Toto models in these older homes more than anywhere else in the city. Sometimes it’s a replacement; often it’s an affordable seat and hinge swap.
- Permit complications on foothill bathroom remodels. A Toto toilet swap in a 91784 home isn’t the same job as one near downtown. The north Upland foothill zone sits under fire-hazard and slope review, which can add plan-check time to a bathroom remodel that includes the fixture change. We handle that paperwork so the toilet doesn’t become the thing that holds up the schedule.
Toto Service in Upland: What Local Conditions Mean for Your Equipment
Upland sits at the base of the San Gabriel Mountains, and that geography splits this city’s housing stock into two very different service realities for Toto owners. Downtown and central Upland is dominated by 1920s – 1960s single-story bungalows and ranch homes with detached garages, knob-and-tube wiring, early galvanized and copper plumbing, and undersized electrical panels. North Upland, the 91784 ZIP, is newer tract and custom foothill housing from the 1970s – 1990s, much of it on hillside and canyon-adjacent lots that trigger fire-zone and slope review, which is why we also offer San Antonio Heights Toto service nearby. So the same Toto toilet job has two different plan-check paths a mile apart. A vanity and toilet swap in a 1940s bungalow on a 40-foot frontage downtown is usually a simple over-the-counter permit. The same fixture change inside a 91784 foothill remodel sits inside a fire-hazard review that can hold the whole bathroom schedule. We’ve done both enough times to know which one you’re facing before we start. Good work doesn’t need a sales pitch; it needs the right materials and someone who knows what they’re doing.
Toto Models & Products We Service in Upland
We install, repair, and replace across the Toto line: the Drake and Drake II two-piece toilets, the Ultramax II one-piece and Vespin II skirted bowls, the Washlet C100 and S350e-class electronic bidet seats, integrated Neorest units, and EcoPower and EcoSeries high-efficiency fixtures for remodels. Our parts approach is specific: anything that touches the water path or electronics gets genuine Toto OEM. Fill valves, flappers, wax rings, Washlet nozzles and inlet screens. We keep the common OEM parts stocked for fast turnaround across Upland, so a Drake running toilet or a scaled Washlet doesn’t sit waiting on a shipped part. When a Washlet’s electronics board or a one-piece bowl itself is failing, we price the honest math against a full replacement. No repeated patches on a sealed unit.

FAQs – Toto Construction in Upland
Yes. The seat mounts on the same bowl footprint, but the electrical and water supply usually need attention in these homes. Original galvanized supply lines sometimes won’t give the Washlet the steady pressure it wants, and the nearest outlet in a 1940s Upland bathroom is often on the wrong wall. We handle the fixture, the supply, and the dedicated circuit where needed. Call (855) 600-3192 for an exact scope.
It’s almost always a worn flapper or a fill valve that won’t seat after Upland’s hot summers and hard water have hardened the rubber and scaled the valve. We replace the offending part with genuine Toto OEM and the running stops. That’s usually a $150 – $300 service call, not a toilet replacement. Call (855) 600-3192 and we’ll confirm what it needs.
Yes, in most cases. A simple toilet and vanity swap in a downtown Upland bungalow is typically an over-the-counter permit with no plan review. The same fixture change inside a 91784 foothill remodel often sits inside the fire-hazard and slope review that covers the broader bathroom project. We pull the permits and know which path applies before we start, and we handle Toto repair in Montclair as well.
The Drake two-piece is our go-to for tight downtown Upland bathrooms: it has a compact elongated option and a standard rough-in that fits most of these older homes. The skirted Ultramax II saves side clearance but can hide a slow leak behind the skirt, so we’re careful about supply routing on install. The Vespin II also works when you need a skirt in a narrow space. We’ll match the model to the actual clearances, not a showroom photo.
Depends on what failed. A scaled nozzle or inlet screen we repair with OEM parts. A failed electronic control board or a heater element means we price the replacement against the cost of a new Neorest or a simpler Washlet-plus-toilet setup. We won’t patch a sealed electronics unit repeatedly and charge you for it. Call (855) 600-3192 and we’ll give you the honest math on your specific unit.
