Toto Construction in Pomona, CA
We provide independent Toto fixture service and bathroom construction across Pomona, from simple toilet resets to full bathroom remodels. Most Toto problems we fix in Pomona aren’t actually the fixture’s fault. They’re the result of a 1920s-era lead closet flange cracking beneath a raised foundation, or a galvanized supply stub that’s been corroding since the Eisenhower administration. If your Toto Drake runs phantom or your Washlet stopped spraying, call Key Step Construction at (855) 382-0824 for a free estimate. We know Pomona’s older housing stock because we work on it every week.
Why Pomona Residents Choose Us for Toto Service
We’ve rebuilt our Toto knowledge the hard way, years of swapping fill valves, flappers, and wax seals on Pomona’s pre-1960 bungalows rather than relying on a factory badge. Our crew works on Toto Drake two-piece toilets, Ultramax II one-piece units, EcoPower and EcoFlush lines, and Washlet electronic bidet seats often enough that we can diagnose most problems by sound over the phone. We’re an independent shop, not authorized by Toto, and we’ll tell you straight when a fixture is worth repairing and when you’re better off replacing the whole unit.
Noel Garrity, our owner, grew up around old houses and learned early that the foundation tells you as much about a toilet leak as the fixture itself. That perspective shapes how we approach every Toto job in Pomona. We don’t just reset the toilet and hope. We check what’s underneath it.
We also carry genuine Toto OEM fill valves, flappers, and gaskets on our trucks because aftermarket kits fit loosely and cause the exact phantom-running complaints homeowners call us to fix. For supply lines and wax rings, we’ll use a quality aftermarket part where it makes no performance difference. That’s not corner-cutting. It’s knowing which parts matter.
If you’re planning a larger bathroom project, our Toto expertise means we handle the fixture correctly while managing the full scope: waterproofing, tile, plumbing, electrical, and finish work. One contractor, every system.

Common Toto Construction Problems We Solve in Pomona
- Phantom running in Drake and Ultramax toilets. Pomona’s hard water leaves mineral scale on the flush valve seal. The seal degrades, water seeps from tank to bowl, and the fill valve cycles every few minutes. We replace the seal with an OEM part and clean the valve seat. The running stops. Your water bill drops.
- Rocking toilets and failing wax rings on raised foundations. Pomona’s clay soils expand and contract with moisture. On 1920s – 1950s bungalows with raised foundations, the old cast-iron or lead closet flange shifts or cracks under that movement. The Toto toilet starts rocking, the wax ring compresses unevenly, and you get a slow sewer-gas leak or water staining at the base. We reset the toilet level and replace the flange when it’s compromised.
- Washlet electronic seat failures from heat and dust. Many Pomona bathrooms built before central AC run hot and dry through summer. The Washlet’s water inlet solenoid and control board accumulate dust and overheat in poorly ventilated spaces. We diagnose whether it’s the solenoid, the board, or a clogged filter before recommending repair or replacement.
- Tank-to-bowl gaskets and bolts leaking on one-piece units. Santa Ana wind events bring rapid temperature swings that stress older Toto one-piece gaskets. You’ll see water beading at the tank seam. Tightening usually makes it worse. We replace the gasket and bolts, then pressure-test.
- Galvanized supply stubs failing mid-install. In the 91766 and 91768 ZIPs, we regularly pull a Toto toilet only to find the original galvanized supply stub corroded thin or already weeping. The toilet swap turns into a repipe-and-flange job before the new fixture can sit level. We quote that before we start, not halfway through.
Toto Service in Pomona: What Local Conditions Mean for Your Project
Pomona’s construction market runs on two very different engines: a large stock of pre-1960 single-family homes, many on raised foundations, that need seismic retrofits, knob-and-tube and early cloth-wiring upgrades, and original plumbing replacement, and a strong commercial industrial stream tied to the Fairplex and the 10/60 freeway corridor. The same contractor has to be equally fluent in historic residential permitting and commercial tenant-improvement work. Neighboring cities like Claremont or Chino don’t have that split the way Pomona does.
For Toto owners, this shows up in the 91766 and 91768 ZIPs frequently. We pull a toilet in a 1940s Spanish-revival cottage and find the original lead closet flange cracked from decades of clay-soil movement under the raised foundation. The homeowner thought the toilet was leaking. The toilet was fine, the flange underneath wasn’t. On a 1940s cottage off the 91766 side of town, our tech pulled a Toto Drake that had been rocking and leaking at the base and found the original lead closet flange had cracked, similar to what we see when handling Toto repair in Montclair. We replaced the flange, reset the toilet with a new wax ring and OEM fill valve, and the phantom-running complaint the homeowner had lived with for months disappeared. The homeowner then had us convert the adjacent tub to a walk-in shower so the bathroom could be finished once.
That’s the pattern: in Pomona, the fixture is rarely the root cause. The 80-year-old plumbing beneath it is. Plan it right the first time and the walls take care of the rest.
Toto Models & Products We Service in Pomona
We service the Toto Drake CST743 and CST744 series, the Ultramax II one-piece line, EcoPower and EcoFlush high-efficiency models, and Washlet electronic bidet seats. For flush mechanisms, we use genuine Toto OEM fill valves, flappers, and gaskets because the aftermarket versions fit loosely and recreate the running-toilet problem. For supply lines, wax rings, and closet bolts, we’ll spec a quality aftermarket part where it performs identically. If the porcelain is sound, we repair. If the bowl or tank is cracked, we recommend full replacement rather than chasing parts over multiple visits.
And when the job expands into Pomona service area bathroom work, we handle the full build: walk-in showers, vanities, tile, and waterproofing under one contract.

AfterToto Service Pricing in Pomona
Toto repair and replacement costs in Pomona follow the scope of the bathroom work, not just the fixture itself. A toilet reset with a new wax ring runs on the low end. A full bathroom remodel with Toto fixtures, a walk-in shower, and new vanity runs materially higher. Here’s the range for common Toto-related bathroom work in Pomona:
| Service | Typical Pomona Range |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Small Bathroom Remodel | $5,000 – $12,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Shower Replacement | $3,000 – $8,500 |
| Bathroom Vanity Installation | $800 – $3,000 |
What drives the cost in Pomona is usually what we find after the toilet comes out: a cracked lead flange, a corroded galvanized stub, or a subfloor that needs reinforcement on a raised foundation. A free estimate tells us what we’re dealing with before you commit. Call (855) 382-0824 and we’ll walk the job with you.

FAQs – Toto Construction in Pomona
Partly. Pomona’s water carries enough mineral content to scale the flush valve seal inside your Drake’s tank. The seal stops seating fully, water seeps into the bowl, and the fill valve cycles to compensate. Jiggling the handle doesn’t fix the seal. Replacing it with an OEM part does. Call (855) 382-0824 for a quick diagnosis, estimates are free.
Yes, and it’s a job we do regularly. The key is checking what the toilet sits on. In 91766, the original closet flange under many 1920s bungalows is lead, and Pomona’s clay soil has shifted it over the years. If the flange is cracked, we replace it before the toilet goes back down. If the flange is sound, we shim and seal properly. Your Toto sits level and stays dry.
Depends on what failed. If the water inlet solenoid is clogged with Pomona dust or the filter is blocked, that’s a straightforward fix and the seat is worth keeping. If the control board is cooked after years of heat in an unventilated bathroom, replacement usually costs more than the seat is worth. We diagnose before recommending either way. Call (855) 382-0824 for an honest assessment.
No. If the existing layout works and the floor around the flange is sound, swapping the toilet is a contained job. But many Pomona bathrooms from the 1920s – 1950s have galvanized supply lines that are near end of life. Replacing the supply stub while the toilet is out makes sense and avoids opening the wall twice. We’ll tell you if that’s the case before we start.
Usually yes. The Toto Drake and EcoPower lines have compact rough-in options, and Wall-hung Toto models free up floor space in tight bathrooms. Your existing footprint matters more than the fixture dimensions. If you’re open to a slight layout adjustment, we’ll show you what’s possible.
