Toto Construction in Houston, CA | Rowan Construction Group
We provide independent Toto fixture installation, repair, and full bathroom remodeling across Houston, TX. What makes our Toto work here different is that we start with the slab, the flood map, and the clay soil before we ever touch a fixture. If you own a Toto toilet or washlet in Houston and it’s rocking, ghost-flushing, or failed after a flood cut, call (470) 298-9650 for a written price before any work starts.
Why Houston Residents Choose Us for Toto Service
Rowan Construction Group has been quoting flat written prices since 2007, and we’ve delivered over 4,000 projects with a documented record on every one. Our crews work inside Houston’s soil-stressed, flood-reassessed homes every week, which means we know how Toto fixtures integrate with the structural reality of black clay slabs, pier-and-beam framing, and Chapter 42 flood rehabs without pretending to be a Toto-authorized dealer. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College where coursework covered framing, concrete, and project estimating before he ever swung a hammer on a paying job. That background matters when a Toto install in Houston turns into a slab correction, because we actually understand load paths and grade beams, not just fixture specs. We’re an independent Toto service provider. We stock OEM Toto fill valves, flappers, and washlet control boards locally for fast Houston turnaround, because aftermarket generics don’t hold calibration against the city’s chloramine-treated water.
Common Toto Construction Problems We Solve in Houston

- Flange offset and wax-ring shear on floor-mount models. Houston’s expansive black clay moves slab foundations year-round, and we regularly see Toto Drake II installations from the mid-2010s in Katy and Pearland slab homes where the flange has shifted enough to shear the wax seal. The toilet rocks, sewer gas enters, and the fix requires re-bedding the flange, not just a new ring.
- Failed washlet electronics after flood cuts. Post-Harvey flood cuts in neighborhoods like Meyerland and Kashmere Gardens open Toto Neorest modules to silt and moisture. The heated seat and dryer circuits fail first, and those require full control-box replacement, not field repair. We quote that honestly before any work starts.
- Ghost-flushing and slow refill from hard, chloramine-treated water. Houston municipal water accelerates internal flapper and fill-valve scaling on Toto gravity-flush models. In 1980s to 2000s tract homes across Sugar Land and Clear Lake, we see Carlyle II and Drake II units that cycle randomly or take forever to refill. OEM replacement parts solve it; generics make it worse.
- Cracked inlet fittings from the 2021 freeze. The February freeze hit uninsulated pier-and-beam crawl spaces in the Heights and Montrose hard. Brittle plastic inlet fittings on Toto skirted one-piece models cracked at the base when supply lines froze, and those leaks only showed up after thaw. We’ve replaced enough of these to know exactly what to check first.
- Rust-stained bowls and internal corrosion from high humidity. Houston’s Gulf Coast climate pushes 50+ inches of annual rain and extreme humidity. Toto one-piece models with exposed metal fasteners or older flush mechanisms corrode faster here than in dryer Texas cities, and we address the moisture source before swapping parts.

AfterToto Service in Houston: What Local Conditions Mean for Your Equipment
Only in Houston does a Toto bid have to answer to Harris County’s substantial improvement rule: if a client’s kitchen or bath remodel pushes the project over 50% of assessed value in a flood-prone neighborhood, the entire slab must be elevated to the new Base Flood Elevation. Our Toto work starts with a Chapter 42 elevation certificate, not a fixture spec sheet. In low-lying areas like Meyerland and Friendswood, where FEMA map revisions after Harvey changed Base Flood Elevation and detention requirements for tens of thousands of properties, a homeowner who just wants a new Toto Neorest in a remodeled bath can legally trigger a whole-house lift. We walk Houston clients through that threshold before any fixture gets ordered, because a five-figure permit surprise is worse than a delayed remodel. That’s the Houston-specific reality most national Toto service pages never mention, and it’s the first question we ask on any job east of the 610 Loop.
Toto Models & Products We Service in Houston

We service the full Toto line Houston homeowners actually install: the Neorest smart-integrated washlet series, Drake II two-piece 1.28 GPF units, Carlyle II one-piece elongated models, and Ultramax II one-piece with Tornado Flush. Our parts approach is straight: we push OEM Toto fill valves, flappers, and washlet control boards because aftermarket generics don’t hold calibration against Houston water chemistry. For high-dollar Tornado Flush bowl swaps, we quote both new retrofit and factory-replacement costs honestly. Sometimes a full wastewater rough-in correction is cheaper than chasing recurring leaks, and we’ll tell you that in writing before you spend a dollar. Our Houston teams also handle Toto sales & service for full bathroom remodels where the fixture and the structural work need to happen in the right order.

What drives the cost in Houston specifically is what the slab and the flood map say. A Toto replacement in a Katy slab home with a shifted flange costs more than the same fixture in a house where the soil hasn’t moved.

FAQs - Toto Construction in Houston
In most cases, a Neorest that sat through flood water should be replaced, not salvaged. Silt gets into the control box, the heated seat and dryer circuits corrode, and the electronics fail within months even if the unit looks dry. If your remodel triggers Harris County’s substantial improvement rule, the elevation work happens first, then the fixture gets replaced. Call (470) 298-9650 for an exact quote on replacement, estimates are free.
Rocking means the flange has moved relative to the toilet base. In Sugar Land and most Houston suburbs, expansive black clay shifts the slab enough to offset the flange and shear the wax ring. The fix is to reset the flange with proper bedding, not to shim the toilet. Call (470) 298-9650 and we’ll inspect the flange before quoting the correction.
It depends on the joist spacing and what’s behind the wall. Heights pier-and-beam cottages often have non-standard framing from early-to-mid 20th century construction, and a wall-hung Toto needs a carrier that ties into the floor or wall framing. Sometimes it’s straightforward; sometimes it means opening the wall. We’ll tell you which, in writing, before you commit.
Replace it. A cracked trapway on a vitreous china fixture cannot be reliably field-repaired, and a failed patch floods your bathroom. The crack usually traces back to slab movement stressing the mounting point. We re-bed the flange and install the replacement with a deep-seal wax ring so the new unit isn’t fighting the same forces that cracked the old one.
Double-flushing after the freeze usually means the fill valve diaphragm or the flapper seal was compromised by ice expansion or the mineral-laden water that followed. An OEM Toto fill valve and flapper replacement solves it in most cases, and the parts cost is modest. Call (470) 298-9650 for an exact quote, estimates are free.
