Toto Construction in San Antonio Heights, CA | Sycamore Contractors
Sycamore Contractors provides independent Toto installation, repair, and full-bathroom construction across San Antonio Heights, including all of 91784. We service Drake, Ultramax II, EcoPower, EcoFlush, and Washlet lines, and we’re known locally for fixing the ghost-flushing and seal failures that hillside slabs and hard foothill water cause. If you need a Toto toilet reset, a Washlet outlet added, or a complete bath remodel around a Toto fixture, call (877) 265-6284 for a free estimate. The one thing that makes our Toto work different here: we understand San Bernardino County permitting and slope drainage, not just the fixture.
Why San Antonio Heights Residents Choose Us for Toto Service
Most plumbers can swap a toilet. Fewer can diagnose why a Toto Drake’s G-Max flush tower sticks open after three summers of mineral-heavy water, and fewer still can reset a flange on a terraced slab that’s moved a quarter inch with the hillside. We do both, and we do them as part of a larger construction picture: bathroom remodels, walk-in showers, vanity installation, and the electrical work a Washlet seat needs. Our lead on this side of the business is Nate Calloway, who grew up in Temecula and has spent his career working Southwest Riverside and the foothill communities above the valley. Nate’s rule on Toto units is simple: the vitreous china outlasts the internals, so we repair before we replace unless the math says otherwise. That approach saves San Antonio Heights homeowners real money, especially on Drake and Ultramax models that were built to run for decades.
We’re a Toto sales & service specialist in the practical sense, not a factory affiliate. That independence is the point: we’re not motivated to sell you a new unit when an OEM flush tower and a supply line will fix the problem for a fraction of the cost. For San Antonio Heights, we keep common Toto OEM parts on hand because the drive up from the valley shouldn’t add a second trip to a repair.

Common Toto Construction Problems We Solve in San Antonio Heights
Here’s what we see repeatedly in San Antonio Heights homes, and why these failures cluster here more than on the flat grid subdivisions below:
- Ghost-flushing Drake and Ultramax toilets. The G-Max and Tornado flush towers in these units hang open as mineral scale builds up, and the fill valve cycles on its own every few minutes. In San Antonio Heights, hard well water and seasonal sediment from older supply lines accelerate that scale. We replace the tower and valve with genuine Toto OEM parts, which fixes the ghost-flushing permanently instead of just temporarily.
- Wax ring and flange failures on hillside slabs. Terraced lots shift slightly over time, and that flex reaches the toilet’s drain connection. A cracked wax ring shows up as a slow leak at the base or a sewer smell in the bathroom. We reset the flange, level the connection, and use a seal that tolerates the movement better than the original wax.
- Washlet seats that stop heating or won’t extend the wand. The S-series and C-series seats are well built, but hard-water scale shortens the life of the wand motor, and the power cycling that happens during Santa Ana wind events and summer brownouts stresses the control board. If both are failing, we’ll tell you outright: replacement often costs less than rebuilding the seat.
- Supply-line and fill-valve breakdowns on EcoFlush and older Ultramax toilets. Hot, dry summers bake the rubber and plastic internals until they get brittle. The symptoms are a slow tank refill or a hissing sound behind the bowl. OEM replacement parts solve it in one visit.
- Tank-to-bowl gasket weeping on any Toto model. The gasket between tank and bowl dries and cracks over time, especially in homes that sit empty during the hottest months. Water seeps down the back of the bowl and puddles at the base. We replace the gasket and check the fill valve while we’re in there.
Toto Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights is not Upland. It’s an unincorporated foothill community where the San Gabriel Valley runs into the San Bernardino Mountains, and every construction decision on these hillside lots gets filtered through slope, drainage, and San Bernardino County review. That matters for Toto work in a very specific way: when you relocate a toilet drain in a bathroom remodel, or when you add a dedicated electrical outlet for a Washlet seat, the fixture and rough-in go through county plan check, not a city building department. On a terraced lot, the drain slope and venting have to be engineered for the grade. You can’t drop a flat-slab plumbing layout onto a hillside and walk away. Contractors who mostly work the valley floor in Upland or Rancho Cucamonga don’t carry that habit. We do, because we’ve been running jobs in the unincorporated foothills long enough to know what the county reviewer will flag before the plans even go in. That’s the difference between a permit that clears the first time and a remodel that stalls for six weeks over a drain slope correction.
One more thing about the water up here. A lot of San Antonio Heights homes are on private wells or older supply lines, and the mineral content is harder than what runs through the municipal systems below. That’s why we see Toto fill valves and flush towers scale up faster here than in the flats. It’s also why we recommend OEM Toto internals rather than generic aftermarket parts for anything that moves water: the tolerances are tighter, and the materials handle mineral exposure better over the long run.
Toto Models & Products We Service in San Antonio Heights
We work on the full Toto lineup that shows up in San Antonio Heights homes. That includes the Drake in both elongated and round-front configurations, the one-piece skirted Ultramax II, the EcoPower and EcoFlush high-efficiency models, and the Washlet electronic bidet seats in the S-series and C-series. Our parts approach is straightforward: genuine Toto OEM fill valves, flush towers, gaskets, and Washlet components when the unit is worth keeping, and quality aftermarket seals and supply lines where OEM adds no functional benefit. For San Antonio Heights specifically, we keep the most common Drake and Ultramax OEM parts stocked so we can complete most repairs in a single trip up the hill. Whether the job is a new Toto rough-in during a bath remodel or a failing Washlet that needs board-level diagnosis, we handle it as a construction company, not just a fixture swap.

AfterToto Service Pricing in San Antonio Heights
What you’ll pay depends on scope. A Toto-specific repair like a flush tower replacement is a small job. A full bathroom remodel built around a Toto fixture is a construction project. Here are the ranges we work within for San Antonio Heights:
| Scope of Work | Price Range |
|---|---|
| Full Bathroom Remodel (Toto fixture rough-in and reset included) | $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 |
The cost drivers are real and local: whether the drain needs to be relocated on a sloped floor, whether the county requires plan review on the rough-in, whether the wall behind the vanity or shower needs repair, and whether we’re adding a GFCI circuit for a Washlet. A free estimate means we walk the actual bathroom, check the existing drain and supply lines, and give you a written number before any work starts. Call (877) 265-6284 to schedule yours.

FAQs – Toto Construction in San Antonio Heights
In San Antonio Heights it’s usually both. The ghost-flushing itself is the G-Max flush tower hanging open from mineral scale, and the water up here accelerates that buildup because many homes are on wells or older supply lines with harder water than the valley floor. The fix is an OEM Toto flush tower and fill valve, which we keep stocked for single-trip repairs. The city water isn’t the problem; the water quality is a contributing factor. For an exact diagnosis and quote, call (877) 265-6284 and we’ll come take a look.
It depends on whether an electrical outlet already exists at the toilet. If the bathroom already has a GFCI outlet within reach, a Washlet seat typically installs without a permit. If we have to run a new dedicated circuit, that electrical work goes through San Bernardino County review because San Antonio Heights is unincorporated. The same applies if you’re relocating the drain or adding a new fixture during a remodel. We pull whatever permits the scope requires and handle the county plan check.
Yes, if the flange and drain connection are reset properly for the slope. On terraced San Antonio Heights lots, the slab or pier-and-beam assembly moves slightly over time, and a standard wax ring flexes once and fails. We level the flange, check the drain slope, and use a seal that tolerates that movement better than wax. The toilet itself is rarely the problem; the connection to the floor is.
If it’s the control board or the wand motor failing alone, we can repair it with genuine Toto Washlet components and get you more years out of the seat. If both the board and the motor are going, and the unit has years of hard-water scale on top of that, replacement is usually the better financial decision. We’ll give you real numbers for both paths rather than steering you one way. Call (877) 265-6284 for an honest assessment and written estimate.
A small bathroom remodel in San Antonio Heights runs $5,000 to $12,000, and a full remodel with a new Toto fixture, walk-in shower, and vanity typically lands between $9,000 and $28,000. Hillside drain relocation, county plan review, and added electrical for a Washlet can all move the number. We give you a written line-item estimate specific to your home, not a ballpark.
