Toto Construction in Mentone, CA | Moreno Valley Builders
We provide independent Toto service and installation across Mentone and Toto in Yucaipa, and the one thing that separates our work here is the geology. Mentone sits where decomposed granite slopes meet sandy alluvial wash, and that ground truth shapes how a Toto gets set, leveled, and kept leak-free in ways a Redlands or Highland job never has to answer to. If you’re dealing with a rocking Toto, a Washlet that’s scaled up on canyon well water, or a Drake that won’t stop running in your Mentone ranch home, call us at (877) 752-3154. We know these fixtures inside out, and we know this town’s ground under them.
Why Mentone Residents Choose Us for Toto Service
Noel Trevino grew up in the Sunnymead Ranch area and has spent the better part of three decades building and renovating homes across the Inland Empire, so he’s seen what Mentone’s soil does to plumbing over time. Our crews work on Toto toilets, Washlets, and lavatory fixtures in old town Craftsman homes, custom hillside builds, and rural parcels with detached outbuildings. We’re not a Toto dealer. We’re a General Contractor in Mentone with deep hands-on experience fitting Toto fixtures into the exact housing stock this town actually has, and we source OEM parts to match the model families owners here genuinely own. That independence means we’ll tell you when a $30 fill valve fixes the problem instead of pitching a new fixture.
We’re state-licensed and insured, and we carry the plumbing fixture lines Toto owners expect alongside the remodel scope that often comes with it: a vanity swap, a tub-to-shower conversion, a floor repair under a failed wax ring. One contractor. Every phase.

Common Toto Construction Problems We Solve in Mentone
- Phantom refills and running toilets in Toto Drake and Eco Ultramax tanks. Mentone’s hot, dry summers bake the rubber components inside fill and flush valve assemblies. We get calls where the toilet refills itself every twenty minutes, all day. The fix is usually an OEM fill valve and flapper swap, not a new fixture.
- Washlet seats scaled up from canyon-area well and softened water. Mineral-heavy water from local wells leaves deposits on the wand nozzles and inside the seat’s internal valve body. Symptoms are weak spray pressure, erratic operation, or a seat that just won’t heat. We break these down, descale internals where possible, and replace the valve body when it’s beyond saving.
- Aquia dual-flush cartridges and seal gaskets degrading. The dual-flush mechanism on Toto Aquia models has more moving parts, and in Mentone’s alternating wet-dry cycles those seals crack and leak slowly. Owners often don’t notice until the bathroom floor near the base shows water staining. At that point it’s not just a cartridge; it’s a subfloor check, especially in older Craftsman bathrooms.
- Wax rings and closet flange bolts failing on slab-on-grade ranch homes. In mid-century ranches near the old town center, the toilet flange sits right on a concrete slab. Temperature swings and the sandy alluvial soil beneath shifts things just enough over decades that the flange loosens and the wax ring loses its seal. The tell is a slight rock when you sit or a faint sewer smell at the base.
- Bowl and base cracking on hillside lots. On crafton-area slopes where decomposed granite moves a fraction with every wet-dry cycle, a toilet that’s even slightly out of level carries stress into the vitreous china. We’ve pulled fixtures with hairline cracks at the base that were never going to seal right. If the china is cracked, replacement is the answer; if the guts are shot, we rebuilt them.
Toto Service in Mentone: What Local Conditions Mean for Your Equipment
Mentone’s crafton-area hillside lots sit on decomposed granite, and the flat valley floor along Mentone Boulevard is underlain by sandy alluvial wash soils left by decades of Mill Creek flooding. That’s not background trivia; it changes how a Toto install plays out. On a hillside lot, a toilet set on a slab that’s shifted with the slope will rock, and a rocking toilet eats wax rings and flange bolts faster than anything else we see. On the valley floor, sandy alluvial soil drains fast and dry, which means the subfloor under an older bathroom can look fine from above while moisture from a slow leak spreads beneath. When we set a Toto in Mentone, we’re checking the flange for level, inspecting what’s underneath, and accounting for the ground movement this town lives with. If the details aren’t right on paper, they won’t be right in the wall.
There’s also the permitting reality. Much of Mentone is unincorporated San Bernardino County, so anything beyond a straight fixture swap runs through County Land Use Services rather than a city building department. We know those requirements. We pull the permits, handle the setbacks, and get the inspection passed.
Toto Models & Products We Service in Mentone
We work on the Toto model families we actually see in Mentone homes, not a catalog someone handed us. That means the Toto Drake CST744 series two-piece, the Eco Ultramax one-piece, the Aquia dual-flush, and the Washlet electronic bidet seat lineup from the C100 era through the newer S550e. We stock OEM fill valves, flappers, and common Washlet internals for these lines so a Toto sales & service call usually gets resolved in one visit. When OEM parts are gone for a discontinued line, we’ll tell you that upfront and talk through the aftermarket option. On a Toto, honest repair is almost always worth it. The vitreous china body outlasts the internals by decades, so we replace the guts, not the toilet, unless the bowl or base is cracked.

AfterToto Service Pricing in Mentone
What you’ll pay depends on whether this is a straight internal repair, a fixture reset, or a larger bathroom scope that includes the Toto work. Here’s what our Mentone customers see across the most common scenarios:
| Service | Price Range |
|---|---|
| Small Bathroom Remodel | $5,000 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Bathroom Vanity Installation | $800 – $3,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Full Bathroom Remodel | $9,000 – $28,000 |
A straight Toto fill valve or flapper replacement runs well under any of these numbers. The cost climbs when we’re resetting a flange, opening a floor to address subfloor damage, or tying the Toto into a remodel. Every estimate is a written line-item quote, and we don’t change the number once work starts unless you add scope. Call (877) 752-3154 for an exact figure. Your project. Your material choices.

FAQs – Toto Construction in Mentone
Yes, and it’s one of the most common calls we get from canyon-area homes. Mineral-heavy well or softened water builds scale inside the wand nozzles and the internal valve body, and we carry OEM replacement components for the Washlet lines most of these homes have. We’ll disassemble, descale what’s cleanable, and replace what’s worn. Call (877) 752-3154 and tell us the model on the seat’s underside label; we’ll tell you what it needs.
In almost every case it’s a worn fill valve or flapper, and Mentone’s hot, dry summers age those rubber and plastic internals faster than coastal climates do. The fix is an OEM fill valve and flapper, not a new toilet. If the tank components are fine and it still runs, we start looking at the flush valve seal and the water level setting. Call (877) 752-3154 for a service visit; we’ll identify the exact cause and quote it before touching anything.
We do, and we approach them differently than a flat valley install. Decomposed granite slopes shift with wet-dry cycles, so we’re checking the slab for level, the flange for solid anchoring, and the drainage path before we set the fixture. If the slab has moved, we’ll tell you what’s needed to get the Toto level and leak-free. We pull the County permits when the scope calls for it, and we handle inspections.
Yes. We’ve set plenty of Toto Drake and Eco Ultramax fixtures into early-1900s Craftsman bathrooms, and it comes down to rough-in dimensions, finish, and the style of the room. A Drake two-piece often sits better in a period bathroom than a modern one-piece, but we’ll show you the options rather than pick for you. On a Craftsman near the old town center off Mentone Boulevard, our crew pulled a Toto Eco Ultramax that had been rocking on a loose closet flange for years, with seepage softening the subfloor beneath. We reset the flange, replaced the worn wax ring and OEM fill valve, and tied the repair into a small bathroom remodel so the vanity and tub-to-shower conversion matched the period of the house. That homeowner got a solid, level Toto back in service instead of a full fixture replacement. Call (877) 752-3154 to talk through what’s possible in your bathroom.
No. We’re an independent Toto service and installation provider, not a Toto-authorized dealer or manufacturer affiliate. That independence means we recommend repairs based on what the fixture actually needs, not what earns us a markup. We use OEM Toto parts whenever the model is still supported, and we tell you when it isn’t. If you want a manufacturer warranty route, we’ll point you to an authorized provider; if you want an honest fix at a fair price, we’re who Mentone homeowners call.
