Toto Construction in San Antonio, TX | Mason Remodeling Co San Antonio
We’re an independent Toto service provider serving San Antonio homeowners. If your Toto toilet rocks, leaks at the base, or your Washlet has stopped working properly, we fix it. What separates us from an authorized dealer is simple: we’ve spent years pulling Toto fixtures out of homes built on clay soil, pier-and-beam frames, and post-tension slabs, and we know exactly how this city’s ground movement breaks them. Call (254) 269-5071 for a free estimate.
We service every major Toto line, from Toto sales & service support on existing fixtures to full bathroom remodels built around a new Neorest or Drake. Mason Remodeling Co San Antonio has been doing this work since 2004, and Isaac Pruett, our owner, still walks job sites himself. We’re not manufacturer-affiliated. We’re not an authorized warranty center. What we are is a local crew that knows Toto equipment and San Antonio foundations equally well.
Why San Antonio Residents Choose Us for Toto Service
Most Toto issues in San Antonio aren’t the toilet’s fault. They’re what the ground does to the toilet. That’s the real distinction, and it’s why our approach starts with the floor, not the fixture. Isaac Pruett grew up in Los Angeles and learned construction fundamentals at Los Angeles Trade-Technical College, then spent two decades working projects across the Southwest. He and our crew have run Toto installs and repairs across San Antonio for years, from gut renovations near the King William Historic District to Bathroom Remodeling in San Antonio in the Stone Oak area and the north-side neighborhoods where slab-on-grade homes dominate.
We use OEM Toto parts for critical water-path components like fill valves, flush towers, and Washlet electronics. For non-warranty cosmetic pieces like toilet seats and bolt caps, we offer compatible aftermarket options that match Toto’s finish. That gives you a real choice: pay for factory parts where they matter, save where they don’t. Every quote is written before work begins, and every job is covered by our 365-Day Done Right Promise. If something’s not right within a year, we come back and fix it at no charge.

Common Toto Construction Problems We Solve in San Antonio
Here’s what we actually see in San Antonio homes, week after week:
- Hairline cracks at the toilet bowl base. Expansive clay soil shrinks and swells with moisture. On 1970s-1990s slab-on-grade homes across the north and west sides, that movement transfers up through the slab and into the porcelain. We’ve seen cracks form at the base of Toto Drakes and Ultramaxes that had nothing wrong with them except the ground underneath.
- Wax ring failures and loose floor flanges. Post-tension slab homes aren’t immune to heave, and when the slab shifts, the flange shifts with it. The wax ring compresses on one side, waste gas seeps out, and the toilet starts rocking. Replacing the ring without addressing the flange gets you six months, maybe. We reset both.
- Hard water scale in Washlet nozzles and Neorest rim jets. San Antonio’s water is mineral-heavy. Scale builds up inside Washlet spray nozzles and clogs the rim jets on Neorest units, reducing flush performance and eventually damaging internal seals. Regular descaling helps, but if it’s already clogged, we clean it right or replace the affected components with OEM parts.
- UV degradation of exterior Toto plumbing components. Outdoor showers and exterior-mounted fixtures with Toto trim take a beating here. Over 100°F summer highs and relentless sun break down plastic shrouds, gaskets, and finish coatings faster than in cooler climates. We replace those components with UV-rated or OEM equivalents that hold up.
- Leaning or rocking toilets on pier-and-beam foundations. In Alamo Heights and Terrell Hills, the older 1950s houses sit on wood beams that settle during dry spells. That settlement pulls flanges and supply lines out of alignment, and the toilet starts to lean. We shim, re-secure, and re-seat the fixture so it sits level again.
Toto Service in San Antonio: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Toto service page. San Antonio sits on some of the most reactive clay soil in Texas, and the city’s unique “flash drought” pattern means the ground can go from saturated to bone-dry in a matter of weeks. When that happens, the clay contracts. In neighborhoods like Alamo Heights and Terrell Hills, a 1950s pier-and-beam house can drop an inch just during one dry summer, and late August is when the most dramatic cracks suddenly appear overnight. That’s not a plumbing problem. That’s a structural one, and it lands on your bathroom floor.
We’ve pulled Toto toilets in Alamo Heights where the flange had dropped nearly half an inch below the finished floor. The toilet wasn’t broken. The floor had moved. Our fix involved removing the fixture, resetting the flange on a reinforced subfloor, and reinstalling everything with new closet bolts and a fresh wax ring. If we’d just swapped the toilet for a new one, the new one would have rocked within a year. In San Antonio, you don’t just repair a Toto fixture. You repair the connection between the fixture and the ground it sits on.
Toto Models & Products We Service in San Antonio
We work on the full Toto line, and we see enough of each model to know their failure patterns here. The Toto Neorest is a luxury integrated toilet with electronic controls, heated seating, and automatic flushing. The Toto Drake is the two-piece gravity workhorse, common in mid-range San Antonio remodels. The Toto Ultramax is the one-piece version, popular in tighter bathroom footprints. The Toto Washlet line includes bidet seats and integrated systems that bolt onto existing Toto and non-Toto fixtures. We keep common OEM components in local stock for fast turnaround on Drakes and Ultramaxes. For Neorest and Washlet electronics, we order OEM parts directly, and most arrive within a few business days.
If you’re planning a bathroom project that includes Toto fixtures, we’re your crew for that too. Our team handles tub-to-shower conversions, walk-in shower installations, and full bathroom remodels across the San Antonio area. We’ll spec the fixtures, handle the plumbing, tile the walls, and make sure everything drains and seals correctly on the first day. We also cover the broader San Antonio service area for any plumbing or construction work tied to your Toto equipment.

AfterToto Service Pricing in San Antonio
These are the prices we quote on Toto work in San Antonio. They’re honest ranges that reflect what the job actually involves here:

| Tub-to-Shower Conversion with Toto fixtures | $3,500 – $10,000 |
| Bathroom Remodel with Toto installation | $9,000 – $28,000 |
What drives the cost on Toto-specific work is the condition of the floor and flange. A simple reset on a solid slab is on the lower end. A pier-and-beam repair that requires subfloor reinforcement runs higher. A full remodel with a San Antonio General Contractor for a Toto Neorest and custom tile is a different conversation entirely.

FAQs – Toto Construction in San Antonio
The clay soil under San Antonio shrinks during dry spells and swells after rain, which moves your slab or beams and puts stress on the toilet flange and wax ring. Over time, that movement cracks the seal, causes leaks, and makes the toilet rock. We address the floor connection during installation, not just the fixture, so the Toto unit stays stable through the next drought cycle. If your toilet is already showing signs of movement, call (254) 269-5071 and we’ll take a look.
Yes. We do tub-to-shower conversions throughout San Antonio, and we install Toto fixtures as part of the job if that’s what you want. The conversion removes the old tub, waterproofs the new shower pan and walls, installs the Toto shower valve and trim, and finishes with tile or solid-surface surround. The cost ranges from $3,500 to $10,000 depending on the size and finish level. Call (254) 269-5071 for an exact quote.
San Antonio’s water is loaded with dissolved minerals, primarily calcium and magnesium, and they bind to the Washlet’s internal spray nozzle and heating elements. Regular surface cleaning doesn’t reach the internal passages where the scale actually builds. Eventually the nozzle clogs or the heater burns out. We disassemble the unit, descale or replace the affected OEM components, and in some cases recommend a point-of-use water softener for that bathroom. Get a free estimate at (254) 269-5071.
Almost never. In San Antonio, a wobbling toilet means the flange or subfloor has shifted, not that the porcelain is cracked. In most cases we reset the toilet, replace the flange if needed, and re-secure everything on a stable base. The toilet itself goes back in. A reset and flange repair runs $400 to $800 here. Call (254) 269-5071 and we’ll tell you if the fixture is salvageable before you spend money replacing it.
No. We are an independent Toto service provider. We are not manufacturer-affiliated, and we do not process Toto warranty claims. What we do is install, repair, and maintain Toto equipment using OEM parts for critical water-path and electronic components. If your fixture is under warranty, you’ll need to contact Toto directly for a warranty-approved technician. If you just want it fixed right by someone who knows San Antonio’s ground conditions, we’re your crew.
