Toto Construction in Rubidoux, CA | Stallion Contractors
We provide independent Toto service in Riverside and across Rubidoux, covering everything from toilet and Washlet installation to full bathroom remodels where Toto fixtures anchor the design. What makes our Toto work different here is simple: we know how Riverside County permitting, hard water, and mid-century slab plumbing affect these units, because we’ve been inside hundreds of Rubidoux bathrooms built between 1950 and 1980. Ruben Montoya and the Stallion Contractors crew handle Toto repairs, replacements, and new construction installs across ZIP 92501. Call (855) 600-3192 for a free estimate.

Why Rubidoux Residents Choose Us for Toto Service
Most plumbers in Rubidoux can swap a toilet. Fewer know the difference between a Toto Ultramax II’s CEFG flush system and the older G-Max, or which Washlet control board revision fails first in a hot room with single-pane windows. We stock OEM Toto fill valves, flappers, and Washlet boards for the model lines actually installed in Rubidoux homes, and we use aftermarket Fluidmaster and Korky parts where they meet or beat OEM spec. Ruben Montoya grew up in Colton and studied construction at San Bernardino Valley College, where he learned to read slab movement and old cast-iron before he ever touched a finish fixture. That’s why our Toto installs don’t just look right on day one. They hold up five years later.
We’re an independent contractor, not Toto-authorized, and we’d rather tell you that up front than pretend otherwise.

Common Toto Construction Problems We Solve in Rubidoux
- Hard-water mineral scale in the fill valve and rim jets. Rubidoux water carries heavy mineral content, and over time, calcium builds up inside the Ultramax II and Drake II fill valves and rim jets. That produces weak flushes and the ghost-flushing you hear at 2 a.m. We descale the rim with the bowl removed, and if the fill valve is beyond saving, we replace it with the OEM part.
- Washlet electronic failures from summer heat. Intense Riverside County sun through old single-pane windows pushes bathroom temperatures over 100 degrees for hours. Thermal cycling stresses the S550e seat heater and bidet control board, causing phantom activation or a seat that won’t heat. We keep spare Washlet boards in the truck for faster Rubidoux turnarounds.
- High-efficiency Toto clogs on corroded pre-1980 cast-iron drains. Rubidoux’s older homes have cast-iron drain lines that corrode and narrow from the inside. A 1.28 gpf Toto is a great toilet on good pipe, but on a 60-year-old restrictive drain, it can clog. We camera-inspect and clear the line before we blame the toilet.
- Wax ring and flange failures in mid-century slab-on-grade bathrooms. Rubidoux sits on decomposed granite, and slab movement cracks the original cast-iron closet flanges. You’ll see a slow leak at the base of a one-piece Toto colonne. We cut out the old flange, set a new one, and bed the toilet on a fresh wax ring.
- Unpermitted prior bathroom work flagged by Riverside County. A surprising share of Rubidoux bathroom remodels were done without permits decades ago. When we install a Toto shower valve or toilet in a bathroom the county doesn’t have on record, the inspector can red-tag the job. We legalize the prior work as part of the project before the county asks questions.
Toto Service in Rubidoux: What Local Conditions Mean for Your Equipment
Rubidoux is unincorporated Riverside County, and that single fact shapes every Toto remodel and repair we do here. There is no city hall to call. Plumbing and framing permits go through the county’s building and safety department, and their inspectors have seen every trick an Inland Empire homeowner or a fast-buck handyman has tried over the past 50 years. Riverside County inspectors routinely flag unpermitted prior work, converted garages, bootlegged bathroom additions, even a toilet that was moved without a signed-off plumbing alteration, before they’ll approve a Toto install we’re doing now. That’s not bureaucratic fuss. It’s the county protecting you from buying a problem. We handle the legalization paperwork, coordinate the inspection, and make sure the Toto fixture and the plumbing behind it both pass the first time. If you own a home in Rubidoux with a bathroom that was remodeled before you bought it, assume the county has questions. We already know the answers.
Toto Models & Products We Service in Rubidoux
We service the Toto lines Rubidoux homeowners actually own: the Ultramax II, Drake II, Aquia IV, and the Washlet S550e. On any of them, we use OEM Toto fill valves, flappers, and Washlet control boards for critical components. Aftermarket electronic parts fail fast in Rubidoux heat and hard water, so we don’t gamble with them. For flappers, supply lines, and wax rings, we stock Fluidmaster and Korky. If a Toto bowl is cracked or a Washlet on a 10-year-old unit needs a $400 control board, we’ll show you the replacement math and recommend spending your money where it lasts. Beyond stand-alone service, we install Toto as part of full Toto sales & service scopes, including full bathroom remodels, walk-in showers, and tub-to-shower conversions.

FAQs – Toto Construction in Rubidoux
Yes, and that’s a common setup in Rubidoux’s older homes. We run a dedicated GFCI-protected outlet to the toilet area as part of the Washlet install, so the seat doesn’t share a circuit with a hairdryer or space heater. Call (855) 600-3192 and we’ll tell you exactly what the electrical work adds to the price.
In Rubidoux, the usual cause is mineral scale on the fill valve seat or the rim jets, which prevents a clean shutoff and triggers ghost flushes through the night. We disassemble the valve, descale or replace it with an OEM Toto part, and test the flush pattern, offering Toto repair in Highgrove and Rubidoux with the same thoroughness. If the scale has moved into the rim jets, we pull the bowl and clear them too.
For a same-location toilet swap, no permit is required. If we move the toilet, alter drain lines, or touch any plumbing behind the wall, Riverside County requires a permit and inspection. Think of it as the county verifying the work that matters. We pull the permit when it’s required and stand behind the inspection.
The Toto Aquia IV and the Drake II are our go-to choices for compact Rubidoux bathrooms, because both have a smaller footprint than the Ultramax II and fit tighter wall-to-bowl clearances common in 1950s-1970s stucco-over-block homes. We measure the rough-in and door swing before recommending a model. Call (855) 600-3192 for a recommendation based on your actual bathroom dimensions.
Yes. In most cases the seat heater or control board has failed from months of thermal cycling, and we replace the affected component with an OEM Toto board rather than an aftermarket substitute. If the unit is older and the board cost outweighs the remaining lifespan, we’ll show you the numbers and help you decide repair or replacement. Estimates are free.
