Toto Construction in San Antonio, TX | Elmstead Remodeling San Antonio
We’re Elmstead Remodeling San Antonio, and we install, repair, and build around Toto fixtures every week across this city. Independent Toto service, not factory-authorized, which matters because we’ll tell you straight when a part is worth replacing and when a toilet has reached the end of its life. The one thing that makes our Toto work here different: we understand how San Antonio’s hard water, slab settlements, and those old clay sewer lines in established neighborhoods change how a Toto performs. Call (432) 233-0976 for a free estimate.
From Toto sales & service knowledge to hands-on installation in mid-century ranches and new builds on the Edwards Plateau, our crews have worked on hundreds of Toto toilets, bidet seats, and full bath remodels. We carry genuine Toto parts for what touches water and sealing, and we stock the common failure items locally so your fixture isn’t down for a week.
Why San Antonio Residents Choose Us for Toto Service
Graham Stein, the owner here at Elmstead Remodeling San Antonio, trained in the construction trade at Los Angeles Trade-Technical College and has spent decades framing, finishing, and fixing what homeowners actually live with. He writes every scope of work down before a tool leaves the truck. The written price you sign is the price you pay, no line items added after demo day. That’s his signature approach: “Write it down, price it once, do it right.”
We’re a Cedarwell company, and every project runs on the Cedarwell Care Promise: shoe covers at the door, drop cloths on the floors, quiet tools during children’s sleep hours where possible, pet-safe product choices where there’s an option, and a photo of the clean-up before the crew leaves. The 365-Day Done Right Promise follows every completed job, if it isn’t done right, we make it right.
Most San Antonio homes we enter have hard water and slab foundations. That’s the baseline. We know how those two factors interact with Toto’s 1.28 GPF designs, and we plan accordingly. You’re not getting a generic plumbing call where the tech hopes for the best. You’re getting a crew that has seen the specific failure patterns this city produces.

Common Toto Construction Problems We Solve in San Antonio
- Phantom flushes on Drake II and Ultramax II models. San Antonio’s hard water leaves mineral crust on flapper chains and seats. The chain stretches or the flapper doesn’t seat evenly, and the toilet runs or ghosts every few hours. We replace with genuine Toto flappers and adjust the chain to spec, then test through a full fill cycle. You won’t hear the tank refill at 3 a.m. anymore.
- Washlet+ supply line pinhole leaks at the tank connection. In older ranch homes with slab settling, the supply line gets stressed where it meets the tank. We’ve found small pinhole leaks during slab foundation inspections that homeowners never noticed until the drywall below started staining. We replace the line, check the stub-out for movement, and confirm the connection point is stable before closing up.
- Fill valve chatter and slow refills from limestone sediment. Neighborhoods with shallow bedrock, like Alamo Heights and Terrell Hills, have tap water with high calcium content. The sediment clogs the fill valve diaphragm, causing chattering or a toilet that takes forever to refill. We swap in a new genuine Toto fill valve and show you what the old diaphragm looked like so you understand the issue.
- Torn tank-to-bowl gaskets after slab movement. Soil shifts under the slab; the flange moves a fraction; the gasket tears. We see this on Promenade and Drake models in homes built before the 1990s. The first sign is usually seepage at the base or a toilet that rocks slightly. We pull the bowl, inspect the flange, and reset everything with a new genuine Toto gasket.
- Complete fixture replacement when repair doesn’t pencil out. If the bowl and tank both have damage or the trapway is cracked, we recommend replacement over repair on most Toto models under $500. A new Drake II runs about $350 to $450 for the fixture alone, and installation with haul-away is a better long-term call than chasing cracks.
Toto Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio is one of the few major Texas cities that still operates a combined sanitary sewer and stormwater system in many older neighborhoods. That means rainwater and sewage flow through the same aging clay pipes in areas like Terrell Hills, Alamo Heights, and parts of the near East Side. Toto’s low-flow toilets, at 1.0 and 1.28 gallons per flush, send less water through those pipes than older high-flow models did. When a line has partial blockages or roots intruding, the lower flush volume doesn’t clear the waste as effectively. A toilet that flushes fine in Alamo Ranch, where newer subdivisions have separate sewer lines, may struggle in Terrell Hills for reasons that have nothing to do with the toilet itself. We see this pattern regularly. The fix isn’t always the toilet: sometimes it’s a sewer line camera inspection and clearing, sometimes it’s adjusting the fill valve to maximize flush pressure, and sometimes it’s a combination. But you need a contractor who knows the difference between a Toto problem and a San Antonio sewer problem. We do.
Our crew worked on a 1962 ranch in Terrell Hills where a Toto Drake II was wobbling on a cracked tile floor. The slab had settled enough to pull the flange a quarter inch out of alignment. We pulled the toilet, found the tank-to-bowl gasket half-split, replaced the flange with a stainless repair ring, reset the bowl with a new genuine Toto gasket, and shimmed it level. No more rocking, no more seepage at the base.
Toto Models & Products We Service in San Antonio
We service the Toto Drake II (CST454CEFG), Ultramax II (MS604114CEFG), Washlet+ (SW2024#01), and Promenade (CST424SF), plus most other Toto models you’ll find in San Antonio homes. Our rule on parts: anything that touches water flow or sealing gets genuine Toto components, fill valves, flappers, gaskets, supply lines. Universal aftermarket parts often cause intermittent flushing problems in Toto’s 1.28 GPF designs, and chasing those gremlins costs more than the savings was ever worth. For cosmetic items like bolt caps and seat hardware, we offer quality OEM-equivalent parts where they hold up fine.
We stock the common failure items locally, so a flapper or fill valve replacement doesn’t mean waiting on a shipment. For larger installations, like Bathroom Remodeling in San Antonio built around a Toto Washlet+, we order the fixtures early and inspect them before your crew shows up so there are no surprises on install day.

What drives the cost: access to the toilet flange, whether the shutoff valve needs replacement, the condition of the existing supply line, and whether we’re working around slab repair or tile that has to be cut to match. A free estimate includes walking the space, checking the flange, confirming the shutoff valve actually closes, and writing the scope down so you can compare it against anyone else.

FAQs – Toto Construction in San Antonio
Can you adjust a Toto Drake II to stop a phantom flush caused by San Antonio hard water?
Yes. The usual culprit is mineral buildup on the flapper or flapper seat, along with a chain that has stretched slightly out of spec. We clean the seat, replace the flapper with a genuine Toto part if needed, set the chain length correctly, and test through several fill cycles. If the issue persists after that, we look at the fill valve and the flow rate from the shutoff. Most phantom flushes are solved in one visit, and the fix is typically under $350. Call (432) 233-0976 to schedule a service call.
Will a Toto Washlet+ work with the old galvanized supply lines in my Alamo Heights home?
It depends on the condition and diameter of the existing supply line and the shutoff valve. Galvanized lines corrode from the inside over decades, reducing flow and sending rust sediment into the Washlet+’s inlet screen. In many Alamo Heights homes built before the 1970s, we replace the last section of galvanized with a braided stainless supply line and a new quarter-turn shutoff at the same time we install the Washlet+. On homes where the galvanized is severely restricted, we’ll recommend replacing the visible supply run before the seat goes in. You’ll know the cost before we start.
Is a Toto Ultramax II a good choice for a bathroom over a slab foundation in San Antonio?
Yes, with one caveat. The Ultramax II’s one-piece design means no tank-to-bowl gasket to tear when slab movement shifts the flange, which is a real advantage in San Antonio’s expansive clay soils. You’ll want the closet flange inspected before installation, and on older slabs where the flange is rusted or out of level, we’ll install a stainless repair ring or a new flange to make sure the bowl seats flat and doesn’t rock. That inspection is part of our free estimate.
Can you convert my tub to a walk-in shower and replace the toilet with a Toto in one project?
Yes. As a San Antonio General Contractor, we do full bathroom remodels and tub-to-shower conversions as part of the same job, and installing a Toto toilet alongside a new walk-in shower is common in San Antonio homes. You’ll get one written price for the whole scope before demo starts: demolition, pan installation, waterproofing with Schluter systems, tile, shower door or curtain rod, and the Toto fixture installation. The 365-Day Done Right Promise covers every part of that work. Call (432) 233-0976 for a free estimate.
Why is my Toto Promenade gurgling after heavy rains in Terrell Hills?
The gurgling usually isn’t the toilet’s fault. Terrell Hills sits on the older combined sewer system we mentioned earlier, and when heavy rain adds stormwater to the same line, the pipe fills to capacity and air gets displaced. Your Toto’s low-flow flush may not clear the bowl fully during those events, or the trap seal may bubble. We start with the toilet, checking the fill valve and flush pressure, but if the issue only appears during heavy rain, the likely fix is a sewer line camera inspection and possibly clearing the line. Estimates are free, call (432) 233-0976 and we’ll figure out which problem you actually have.
