Why Houston Homeowners Choose Toto Construction
We provide independent General Contractor services for Toto construction, repair, and installation across Houston, from inner-loop bungalows to Memorial-area colonials and newer builds in Katy and The Woodlands. Our crews have installed and repaired hundreds of Toto toilets, Washlets, and sinks in this city’s humid, hard-water environment, so we know exactly which models hold up and which ones need specific attention. We are not authorized by or affiliated with Toto, and we’ll tell you that plainly. What we bring instead is field experience: the kind you only get from opening a Drake II that’s been fighting Houston water for a decade and finding the real reason it flushes weak. Call (254) 527-5340 to talk through your Toto fixture, whether it’s a repair, a replacement, or part of a full bathroom remodel.
Why Trust Penhallow Remodeling Houston for Your Toto Construction?
Most contractors treat a toilet as a commodity: pull it, swap it, move on. Toto repair in Houston isn’t that simple, and Houston water makes it less simple still. Our technicians know the G-Max and double-cyclone flush systems well enough to diagnose a weak flush by sound before taking the tank lid off. We stock the OEM fill valves, flappers, and supply lines that Toto toilets actually need, and we know which aftermarket parts cause more problems than they solve.
Trevor Nash runs our Houston crews. He grew up learning that a straight wall is harder than it looks, studied construction technology at Los Angeles Trade-Technical College, and spent years on everything from tract homes to full gut renovations. He and our team have spent enough time in Houston homes to know what this city’s chloramine-treated water does to rubber seals over five or six years, and why every bathroom remodel here has to plan for moisture the way other cities plan for cold. When we give you a written price for Toto work, it is a number built on that experience, not a guess.
Every Toto job gets the same written guarantee as any other project we take on: a price in writing before we start, and a 365-day promise that if the work fails, we come back and make it right at no charge. No re-inspection fee, no service call charge on the return visit.

Common Toto Construction Problems We Fix in Houston
- Weak or erratic flushes on Drake II and Ultramax II toilets. Houston’s water is hard, and that hardness leaves calcium scale exactly where it hurts most: the rim jets and the double-cyclone siphon nozzles. The jets that should spin water in a tight, quiet vortex get half-clogged, and you get a lazy flush that leaves paper behind. Descaling with the right acid solution, combined with an OEM G-Max flapper replacement, usually restores the flush completely.
- Stubborn bowl staining on CeFiONtect porcelain. Toto’s photocatalytic glaze resists most buildup, but in Houston bathrooms with weak ventilation, humidity settles and the glaze becomes uneven over time. That leads to stubborn brownish rings that normal scrubbers can’t touch. We use non-abrasive descalers and, when needed, a professional polish that won’t scratch the glaze.
- Constantly running tanks after five to seven years. Houston’s water treatment plants use chloramine, not plain chlorine. Chloramine quietly eats the rubber flapper and fill-valve seals inside Toto tanks. The tank bleeds water silently, the fill valve cycles all night, and your water bill climbs. Replacing the flapper and fill valve with genuine Toto OEM parts stops it, usually in under an hour.
- Washlet control-board failures after storms. Houston gets real thunderstorms, and the power surges they bring are hard on the C5 and S550e control boards. A dead seat heater, a bidet wand that won’t retract, or a remote that stops talking to the seat usually points to the board. We replace these with genuine Toto boards and test every function before we leave.
- Supply-line and angle-stop failures on older installations. In 1970s and 1980s Houston homes we routinely find original angle stops that have never been replaced. When a Toto toilet gets a new fill valve or a supply line replacement, a weak angle stop behind the toilet can shear or fail. We inspect and replace these during any Toto service rather than leave a hidden leak waiting to happen.
Toto Parts & Our Repair-vs-Replace Approach
We default to genuine Toto OEM parts for toilets and Washlets. That is not brand loyalty; it is field reality. Aftermarket flush valves and sensors often have slightly different tolerances, and those tolerances turn into leaks, calibration faults, and callbacks. For discontinued Toto models where OEM parts are no longer in production, we source verified New Old Stock OEM parts or high-grade spec-equivalent alternatives. We tell you which one you are getting and why.
The repair-versus-replace decision is where a lot of companies go wrong. They either push a new toilet because it is a bigger invoice, or they keep patching an old one to look cheap. We don’t do either. If a 15-year-old Ultramax II needs a fill valve, a flapper, and a supply line, that’s a repair and we’ll quote it as one. If the bowl glaze is shot and the flush system has been fighting scale for a decade, a new fixture often costs less than fighting it. We’ll give you the numbers and let you decide. Call (254) 527-5340 for an honest assessment and a written price.
Our Toto Service Process – Step by Step
Every Toto job in Houston follows the same sequence, whether it’s a Washlet board replacement or a full bathroom remodel with a new wall-hung toilet.
- 1
Diagnosis. We listen to the flush, check the tank internals, test the water supply, and inspect what’s behind the fixture. For Washlets we run function tests on the seat, wand, heater, and remote. You get a written diagnosis and a written price before any work starts.
- 2
Repair or installation. We bring the parts we need, including OEM replacements and spare angle stops and supply lines. Work is done by background-checked, uniformed technicians. No subcontractors.
- 3
Testing. Every Toto fixture gets a flush-volume test, a leak check, and a full cycle test. Washlets get every function verified: seat heat, water temp, wand operation, air dryer.
- 4
Warranty documentation. You receive a written guarantee covering the workmanship, with the 365-Day Done Right Promise included. If it fails inside the year, we return and fix it at no charge.

AfterToto Products We Service & Install in Houston
We work on the full range of Toto product lines installed in Houston homes. On the toilet side, that includes the Drake II with its G-Max flushing system, the Ultramax II with double-cyclone flush, the Neorest NX2 smart toilet, and the Soiree and other pedestal and wall-hung models. On the Washlet side, we service the C5 and S550e heated seat bidet lines, including control-board replacement and wand service. We install Toto toilets and Washlets as part of full bathroom remodels, tub-to-shower conversions, and cabinet refacing projects where the existing Toto fixture stays in place. We keep the most common Toto OEM parts on our trucks: G-Max flappers and fill valves, supply lines, and standard Washlet remote batteries and seats.
We Also Service These Brands
Our Houston crews work across the major fixtures and finishes brands, not just Toto. We install and service KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Moen fixtures. If your bathroom remodel keeps the Toto toilet and swaps everything else, we are comfortable across the whole room.
FAQs – Toto Construction Service in Houston
Weak flushes in a Drake II usually mean the rim jets under the bowl’s lip or the double-cyclone nozzles are clogged with calcium scale from Houston’s hard water. Cleaning the bowl surface doesn’t touch these. We descaled a Memorial-area Drake II recently that had half-clogged jets from years of scale; a mild acid treatment and an OEM G-Max flapper replacement restored the flush completely, saving the homeowner a full replacement. Call (254) 527-5340 for a diagnosis and quote.
Yes. We are an independent Toto service provider, not an authorized dealer, and that does not prevent us from installing or servicing Neorest NX2 units. We follow the installation specs Toto publishes, including the electrical and water-supply requirements, and we warranty our workmanship in writing. The unit’s manufacturer warranty still applies to the fixture itself.
Usually, yes. Houston thunderstorms bring power surges that commonly take out the Washlet control board, which is a replaceable part. We replace the board with a genuine Toto component and test every function, including the seat heater, water temperature, and wand. A board replacement runs roughly $300 to $800 depending on the model. If the failure is in the heating element itself, replacement may be the better path. Call (254) 527-5340 and we’ll test it for you.
A 15-year-old Ultramax II that runs constantly usually has a worn flapper or fill-valve seal from years of Houston’s chloramine-treated water, and that’s a repair in the $120 to $260 range for OEM parts and labor. If the bowl also has deep staining, worn glaze, or a compromised flush system, replacement may be cheaper than chasing it. We’ll give you written numbers for both and let you choose. Estimates are free; call (254) 527-5340.
Yes. We do tub-to-shower conversions throughout Houston, and keeping the existing Toto toilet and vanity is common. We build the new shower pan, waterproof the surround, install the new valve and fixtures, and leave your Toto toilet exactly where it is unless you want it moved. A tub-to-shower conversion with a new Toto wall-hung toilet typically runs $5,500 to $12,000, depending on tile choices, glass, and any plumbing changes under the slab. Call (254) 527-5340 to schedule a free estimate.
