Why Austin Homeowners Choose Toto Construction
We provide Toto repair in Austin and independent construction and fixture service across the city, focusing on how Toto toilets, Washlets, and bathroom systems perform inside full remodels, not just as standalone repairs. Our crews work on Toto plumbing and fixtures inside complete kitchen and bath renovations, so we understand how a Toto Drake behaves on an east-side slab or how Austin’s hard water attacks a Washlet inlet filter. We’re not a Toto dealer, and we’re not affiliated with or authorized by Toto. We’re a remodeling company that solves the installation and integration problems Toto fixtures present when tile goes up, vanities get set, and tubs become walk-in showers. Call (903) 623-1966 to talk through your project.
What makes our Toto work different is context. A plumber swaps a toilet. We set that same Toto Drake on a new floor after tearing out the old one, and we know what happens when the flange height is half an inch off after tile goes down. That’s the difference. Isaac Pruett, our owner, learned the trade at Los Angeles Trade-Technical College and has spent years doing residential and commercial work before bringing his crew to Austin. The man can tell you within five minutes whether a ghost-flushing Toto needs a $6 seal or a new fill valve, and he’ll tell you straight.
Why Trust Mason Remodeling Co Austin for Your Toto Construction?

Our technicians work with Toto fixtures every week, usually mid-remodel when the subfloor is exposed and the old toilet is sitting in the hallway. We know Toto’s engineering quirks: the 3-inch flush valve on the Drake, the premixing chamber on the Ultramax, the auto-open sensor logic on the Neorest, and the water-inlet filter on the Washlet that Austin’s limestone-heavy water will clog faster than the manual says. We prefer OEM Toto parts for anything that touches water seals or electronics. For cosmetic trim and supply lines, we’ll use quality aftermarket equivalents when the specs match. The distinction matters, and we’ll explain why on every job.
Every crew member who walks through your door is background-checked, identity-verified, uniformed, and carrying a photo ID badge under what we call the Threshold Standard. You get the technician’s name and photo before the visit. You get a written price before any work starts, every time. And every completed project carries our written guarantee with clearly stated terms, including a free return visit if something fails. That applies to Toto fixture work as much as a full bathroom gut. Isaac runs the crew the same way in Mueller as he did on the West Coast: show up on time, give a straight estimate, and don’t leave until the punch list is actually finished.

Common Toto Construction Problems We Fix in Austin
These are the Toto-specific issues we see most often in Austin homes, especially after a remodel or in older houses with hard water.
- Toto Drake ghost-flushing after a remodel: The flush tower seal in the Drake’s 3-inch flush valve deforms over time, and the tank slowly leaks into the bowl. Every few hours the fill valve kicks on for a few seconds, and homeowner wonders if the house is haunted. In hard-water Austin, mineral buildup accelerates the seal’s breakdown. On a Mueller bathroom remodel, our tech pulled a Toto Drake and found the flush tower seal deformed. We replaced the seal and adjusted the chain, then set the tank on a new custom vanity without straining the supply. Two months later the homeowner called about a different fixture, but didn’t even mention the toilet.
- Toto Washlet inlet filter clogging: Austin water runs hard, and the Washlet’s inlet filter catches scale the way a screen door catches June bugs. When the filter clogs, the Washlet’s spray pressure drops, and the seat may shut off mid-cycle. The fix is straightforward: kill the water, pull the filter, soak it in vinegar or replace it, and put it back. We do this routinely during bathroom remodels when the Washlet gets reinstalled.
- Neorest auto-open lid sensor misalignment: The Neorest’s lid opens by proximity sensor, and that sensor’s aim matters. After tile work, cabinet installs, or a vanity replacement, the sensor can get nudged just enough that the lid opens for passersby but ignores the person standing right in front of it. Recalibrating the sensor position after construction work finishes is part of our final walkthrough on any bathroom with a Neorest.
- Cracked tank gaskets from over-tightening: This happens during vanity and countertop installs when a Toto gets reset and someone channels their inner torque wrench. The tank-to-bowl gasket on a Toto Drake or Ultramax doesn’t need much compression. Over-tighten it, and the gasket splits, causing a slow leak onto the floor. We use a torque-limited ratchet and the manufacturer’s spec.
- Wax ring failures on slab homes: Austin’s east-side blackland prairie clay shrinks and swells, and slab movement can break the wax seal under a Toto toilet. The symptom is a faint sewer odor or a dark ring at the base. On a remodel we’ll reset the flange to the finished floor height and use a wax-free seal that tolerates minor slab movement better than traditional wax.
Toto Parts & Our Repair-vs-Replace Approach

Water seals and electronics get OEM Toto parts, full stop. A flush tower seal, a fill valve diaphragm, a Washlet inlet filter, a Neorest sensor module: these are parts where an aftermarket equivalent might fit but not seal, or might plug in but not talk to the board. We’d rather wait a day for the right part than install something a homeowner has to call us about in three months. Cosmetic trim, supply lines, and mounting hardware are a different story. When the spec matches and the material holds, quality aftermarket parts save real money without adding risk.
Repair versus replace is a conversation we have honestly. A 15-year-old Toto Drake with a failed seal and a cracked bowl from a slab shift? Replace it, and we’ll tell you the replacement cost up front. A Washlet that just needs a filter and a descale? Repair it. We keep common Toto parts on our trucks for faster turnaround on service calls across Austin and Pflugerville Toto service calls, including flush tower seals, fill valves, wax-free seals, and inlet filters. If we need to order something, we’ll tell you when it arrives and set the install date then. Call (903) 623-1966 for an exact quote on your Toto fixture, and we’ll give you a written price before touching a wrench.
Our Toto Service Process – Step by Step
- 1
Diagnosis: We start by identifying the exact Toto model and series on site, then test the specific failure point: flush tower seal condition on a Drake, water pressure and spray performance on a Washlet, sensor function on a Neorest. Isaac’s rule applies here: “Tell me what’s wrong with it. We’ll figure out what it actually needs.”
- 2
Repair or install: We use OEM Toto parts for water seals and electronics, and reset fixtures to manufacturer torque specs. For full remodels, Toto fixture placement is coordinated with tile, vanity, and shower work so the final set isn’t an afterthought.
- 3
Test: Every Toto fixture gets a full-cycle test: flush volume and refill time, bowl water spot and rim wash, Washlet spray pressure and seat functions, Neorest lid sensor and auto-flush behavior. We run the fixture the way you’ll use it, not just a courtesy flush.
- 4
Warranty: Our written guarantee covers the work for 365 days from the completion date. If something fails within a year, we return at no charge. That’s the 365-Day Done Right Promise, and it’s on the paperwork, not just in the conversation.

AfterToto Products We Service & Install in Austin
We service and install across the Toto residential lineup: the Drake and Drake II gravity flush toilets, the Ultramax one-piece high-efficiency models, the Neorest integrated toilet-and-Washlet systems, and the Washlet seats that retrofit onto existing Toto bowls. Our crews install Toto fixtures inside full bathroom remodels, vanity replacements, and walk-in shower conversions, including Toto repair in Round Rock and surrounding areas. On the truck we typically carry Drake flush tower seals, fill valves, wax-free seals, Washlet inlet filters, and supply lines. Special-order parts arrive within a few days, and we’ll coordinate the install around your schedule, not ours.
We Also Service These Brands
Toto isn’t the only name we work with. Our multi-brand capability means we install KraftMaid cabinetry, Cambria and Silestone surfaces, and Kohler fixtures alongside Toto, which matters when a remodel calls for a Toto toilet under a Cambria vanity and a Kohler faucet above a Silestone top. We’re not tied to any single manufacturer, so product choices come down to what works for your bathroom and your budget.
FAQs – Toto Construction Service in Austin

Yes, we clean or replace clogged Washlet inlet filters throughout Austin, and this is one of the most common calls we get. Austin’s water is hard with dissolved limestone minerals, and the filter screens that protect the Washlet’s internal pump clog up faster than Toto’s manual suggests. The fix usually takes under an hour. Call (903) 623-1966 and we’ll schedule a service visit.
Yes, we install Neorest units during full bathroom remodels, and sensor alignment is part of the process. The Neorest’s auto-open lid uses a proximity sensor that can get knocked out of position during tile or cabinet work. We mount the unit per Toto’s clearance specs, then test and recalibrate the sensor at final walkthrough so it opens when you approach, not when someone walks past the door. Get a written price before the tear-out: call (903) 623-1966.
A ghost-flushing Toto Drake after a remodel almost always points to a failed flush tower seal, which is the rubber seal inside the Drake’s 3-inch flush valve that slowly leaks water from the tank into the bowl. When the water level drops far enough, the fill valve kicks on for a few seconds. Remodel work can disturb the mechanism, and Austin’s hard water speeds the seal’s wear. It’s a straightforward parts replacement, not a new toilet. Call (903) 623-1966 and we’ll diagnose it over the phone before scheduling.
Yes, matching Toto fixtures during a remodel is standard practice for us. We coordinate Toto fixture selection with the cabinet order, countertop template, and tile schedule so the toilet, lavatory, and shower trim arrive before tear-out and install in the right sequence. For full bath remodels with Toto integration, budget $9,000 to $28,000 depending on size and materials. Call (903) 623-1966 for a fixed written estimate.
We use OEM Toto parts for anything that touches water seals or electronics: flush tower seals, fill valves, Washlet filters, Neorest sensors. For cosmetic trim and supply lines, we use quality aftermarket equivalents when the specifications match, and we’ll tell you which is which on the written quote. You won’t find an aftermarket seal in a Toto Drake on our watch.
Toto-specific work ranges from a $250-$450 toilet swap to a $9,000-$28,000 full bathroom remodel with Toto fixture integration. Vanity and countertop installs with a Toto lavatory run $800-$3,000. Here’s the breakdown:
| Service | Price Range |
|---|---|
| Full Bathroom Remodel including Toto fixture integration | $9,000 – $28,000 |
| Small Bathroom Remodel with Toto toilet | $5,000 – $12,000 |
| Toto toilet replacement labor (swap existing fixture) | $250 – $450 |
| Vanity and countertop install with Toto lavatory | $800 – $3,000 |
