Toto Construction in Rialto, CA | Sycamore Contractors
We provide independent Toto service across Rialto, from fixture installation in 92376 to full bath remodels toward the 92377 north side, and we also handle San Bernardino Toto service for nearby homeowners. What makes our Toto work here different is the housing stock: most of Rialto’s homes are 1950s through 1980s slab-on-grade tract builds, and when a Toto fixture goes in or comes out, you’re often dealing with cast-iron drains, shallow slabs, and the occasional unpermitted add-on a previous owner left behind. That’s the job. We plan for it, we price for it, and we don’t act surprised when it shows up. Call (877) 265-6284 for a free estimate.
Why Rialto Residents Choose Us for Toto Service
We’ve installed and serviced Toto fixtures across Rialto’s mid-century and newer tract housing for years, from original Washlet-era retrofits to current high-efficiency Drake and Aquia installations. Our knowledge comes from hands-on work in Inland Empire homes, not from any manufacturer authorization. We’re an independent Toto service provider, which means we fix what needs fixing without pushing a product line that doesn’t fit your house, whether you need Toto service in Muscoy or right here in Rialto.
Nate Calloway, who runs Sycamore Contractors, grew up in Southwest Riverside County and spent two decades running crews before starting this company. He’ll tell you the same thing on a Toto service call as he will on a full remodel: do it right the first time, or you’ll do it twice in the July heat. That’s not a slogan. It’s a warning about Rialto summers.
We use genuine Toto OEM fill valves, flappers, wax rings, and Washlet components wherever fit and warranty matter. For non-critical items like supply lines, we’ll use quality aftermarket parts if they hold up as well and cost you less. And we stock the common parts locally, so we’re not making you wait on a shipment when your only toilet is down.

Common Toto Construction Problems We Solve in Rialto
- Fill and flush valve wear from hard Inland Empire water. Rialto’s water is mineral-heavy, and Toto’s fill valves and flapper assemblies take the brunt of it. We see phantom running and weak flushes regularly in homes still running original galvanized supply lines. An OEM fill valve swap usually solves it the same visit.
- Gasket and wax-ring failures at the flange on shallow-slab homes. The 1950s through 1980s tract houses near downtown Rialto sit on shallow slabs with original cast-iron drains. Those drains shift and corrode over decades. The result is slow leaks and subfloor staining around the toilet base. We pull the bowl, inspect the flange, and replace what’s actually failed rather than stacking a second wax ring on a cracked flange.
- SanaGloss glaze micro-cracking and rim jet fouling from thermal cycling and dust. Rialto summers push past 100°F, and Santa Ana winds blow fine dust into everything. The ceramic glaze on the bowl sees repeated expansion and contraction, and those rim jets get caked with mineral and dust deposits. We clean and diagnose the bowl before recommending replacement, which saves money in most cases.
- Washlet electronic and hose failures in older tract housing. The control boards and inlet solenoids in Washlet seats don’t love years of mineral-heavy water and power surges common in Rialto’s older subdivisions. When a board fails repeatedly, we’re honest: sometimes a new seat costs less over three years than chasing the same failure twice.
- Unpermitted bathroom add-ons with undersized drains. This one is specific to Rialto’s older blocks. Previous owners did their own thing, and we respect the ingenuity while fixing the execution. A Toto install in a converted garage bathroom often means correcting a hacked-in floor flange or an undersized drain line before the fixture goes in.
Toto Service in Rialto: What Local Conditions Mean for Your Equipment
In the older blocks near downtown Rialto in 92376, plumbers routinely find unpermitted garage conversions and bathroom add-ons from previous owners. That’s not a knock on the homeowners; it’s just what happens in a city whose housing stock was built fast and modified by hand over six or seven decades. What it means for Toto owners specifically is this: a new Drake or Aquia rarely fails because of the fixture. It fails because the drain line under it was sized for a sink, or the flange was set with drywall screws, or the slab was patched with whatever was in the truck. On a recent job near downtown Rialto, our crew pulled a Toto Drake in a previous owner’s garage-conversion bathroom and found a corroded cast-iron flange and a leaking bowl with a worn fill valve — similar challenges to what we see on Toto repair in Bloomington jobs. We replaced the flange and wax ring, swapped in an OEM fill valve, and re-set the bowl on the existing shallow slab. Smooth flush, no subfloor staining, inside a partial bathroom remodel. That’s the difference between selling a toilet and fixing a bathroom.
Toto Models & Products We Service in Rialto
We work on the full Toto lineup you’re likely to have or want: Drake two-piece toilets (the CST743 series), Aquia dual-flush models in both one-piece and two-piece, EcoPower, EcoPromenade, and Ultramax high-efficiency toilets, plus Washlet and Washlet+ electronic bidet seats with SanaGloss ceramic bowls. On toilets, repair is almost always the right call. The ceramic bowl and trapway outlast everything else on the fixture. When a Washlet control board or an older fill assembly fails repeatedly, we’ll say so and recommend replacement. If you’re planning a Toto install, see our Toto sales & service page for the full scope of what we handle.

AfterToto Service Pricing in Rialto
What you’ll pay depends on the scope. A fill valve swap is a service call. A Toto install in a bathroom that needs drain correction, flange work, and tile repair is a remodel. Rialto’s older homes skew toward the latter, and we’d rather tell you that up front than surprise you at the end. Here’s what Toto-related bathroom work typically runs:
| Service | Typical Range in Rialto |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |

FAQs – Toto Construction in Rialto
You can use us. We’re an independent Toto service provider, not manufacturer-authorized, and we’ve serviced Washlet seats across Rialto’s tract housing for years. For control boards, inlet solenoids, hoses, and seat assemblies we use genuine Toto parts where warranty and fit matter. Call (877) 265-6284 if your Washlet is acting up.
The fill valve or flapper assembly is worn, usually from mineral buildup in Rialto’s hard water. Older homes with original galvanized supply lines make it worse because sediment works its way into the valve. We replace the failing part with Toto OEM and you get a clean shutoff again. Running toilets waste water and money, so call (877) 265-6284 to get it fixed.
Yes, but we inspect the flange and drain first. Shallow slabs and old cast-iron drains are common in Rialto’s mid-century homes, and the install often includes flange correction or drain work before the Aquia goes in. We’ll quote that as part of the job rather than discovering it mid-install. Estimates are free at (877) 265-6284.
Yes, and it’s a smart time to do it. Since the bathroom plumbing is already open during a tub-to-shower conversion, we can rough in the electrical and water line for a Washlet seat without tearing into finished walls later. Rialto tub-to-shower conversions typically run $3,500 – $10,000 depending on tile, glass, and plumbing condition. Call (877) 265-6284 to plan it out.
We do. A full bathroom remodel is the cleanest way to replace a Toto toilet or add a Washlet while correcting drain issues, old valves, and slab conditions all at once. In Rialto, full bath remodels typically run $9,000 – $28,000 depending on scope. Call (877) 265-6284 and we’ll walk the space and give you a written quote.
