Toto Construction in Sunnyvale, CA | Viceroy Construction
Viceroy Construction provides independent Toto service across Sunnyvale, from fill-valve replacements on a Drake to full bathroom remodels built around a new Washlet. What sets our Toto work apart here is that we understand Sunnyvale’s orchard-lot housing stock, where shallow slabs and 10-inch rough-ins from the 1950s and 60s turn a routine toilet swap into an engineered drain relocation. We’re not authorized or endorsed by Toto, and we don’t pretend to be. We’re a general contractor in Sunnyvale that knows Toto equipment well enough to install it correctly and repair it when it fails. Call (877) 358-6557 for a free estimate.
Why Sunnyvale Residents Choose Us for Toto Service
Most plumbers know how to set a toilet. Far fewer know the difference between a Toto Drake CST743 and CST776, or why a Washlet S350e inlet filter clogs faster in the 94086 supply than it does with Toto in Cupertino. Neil Drummond, our owner, spent years on South Bay job sites learning the plumbing trade alongside framing and finish work, and he’s the first to admit the details you don’t see are the ones that matter most. The fill valve seat inside your tank, the rough-in measurement behind the base, the condition of the closet flange under the wax ring. Those decide whether your Toto runs quiet for a decade or phantom-runs your water bill up. We stock genuine Toto parts locally so a Sunnyvale repair doesn’t wait on a warehouse in Reno.

Common Toto Construction Problems We Solve in Sunnyvale
- Washlet seats that stop heating or spraying. Sunnyvale’s water is mild but mineral-heavy, and the inlet filter inside a Washlet S350e or C5 seat is the first thing to clog. Homes in 94086 and 94087 with original galvanized supply lines see this faster. We swap the filter first, then the seat assembly if the board or heater is gone.
- Phantom-running Drake toilets. The flush tower and fill valve in a Toto Drake wear over time, and the plastic fill valve seat scales up in local water. You’ll hear the toilet cycle at 3 a.m. and see the bill climb. A genuine Toto fill valve and flush tower fixes it.
- Rough-in mismatches on Eichler remodels. Gutted original homes off former orchard lots often have a 10-inch rough-in and a shallow slab. A new Toto Ultramax II wants 12 inches. You can’t fudge that with a thicker baseboard. The drain has to be relocated before the slab is touched, and that’s plan-review territory in Sunnyvale.
- Wax seal and gasket failures at the closet flange. When a second-story addition or ADU tie-in stresses the old slab, the flange shifts, the wax ring breaks, and you get seepage at the base. We reset the flange and set a new ring, not just another layer of caulk over the problem.
- Supply line and shutoff replacements during vanity work. If we’re pulling an old vanity in a 94085 ranch and the angle stop is original, it’s often corroded. That’s when a simple Toto swap becomes a shutoff replacement, and it’s better to find it before the water is off, not after.
Toto Service in Sunnyvale: What Local Conditions Mean for Your Equipment
The thing about Sunnyvale is that its own planning and building review governs the orchard-lot Eichler rebuilds, not a neighboring city’s. Those shallow slabs leave no room to reroute a drain underground the way you could in a raised-foundation house in Campbell. So when a homeowner in the 94087 tract off a former orchard lot wants a new Toto in a remastered bath, the rough-in has to be engineered into the plan before the slab is touched. That’s the information crews crossing over from San Jose or Toto in Santa Clara routinely miss. Neil has seen it more times than he can count: a sub shows up with a saw and a new toilet and discovers the drain center is at 10 inches, not 12, and now the homeowner is paying for a slab patch and a re-inspection. We plan the drain first, set the Toto second.
Toto Models & Products We Service in Sunnyvale
We work on the Toto lines Sunnyvale homeowners actually live with: the Drake two-piece series (CST743 and CST776), the Ultramax II one-piece, and Washlet integrated and bidet-seat units in the S350e and C5 class. We also service EcoPower and 1.28 gpf high-efficiency models. We use genuine Toto fill valves, flush towers, and Washlet inlet filters on anything we warranty. For non-critical seals and supply lines, quality aftermarket is fine. Our decision rule is simple: if the bowl and tank are sound, we repair. When a Washlet control board is shot and the unit is past support, we’ll tell you straight that a replacement seat makes more sense than chasing discontinued parts. We sell and service the full Toto sales & service range, so it’s the same crew whether you’re swapping one toilet or gutting three baths.

AfterToto Service Pricing in Sunnyvale
Here’s what full-scope Toto-related work costs in Sunnyvale, based on our recent projects across ZIPs 94085 through 94087:
| Service | Typical Range |

A standalone Toto repair, like a fill valve and flush tower on a Drake, is a smaller line item, but if it’s part of a remodel, it rolls into the scope above. What drives cost on a Sunnyvale bath is almost always what’s behind the wall: drain location, venting, and whether the slab needs to be opened. Our free estimate covers all of that, in writing, before you commit. Call (877) 358-6557 and we’ll walk it with you.

FAQs – Toto Construction in Sunnyvale
No. We are an independent general contractor and remodeler, not a Toto-authorized service provider or dealer. That independence means we recommend the right fix for your house, not the one that protects a manufacturer relationship. We use genuine Toto parts when we repair, but we answer to you, not to Toto.
Yes, and this is one of the most overlooked issues on orchard-lot properties. When you add a second story or an ADU on a small Sunnyvale lot, the old shallow slab and drain lines get stressed. What was a solid closet flange can shift enough to break a wax seal. And if your addition changes the bathroom footprint, the new Toto’s rough-in has to be engineered into the plan under Sunnyvale’s review process, not patched in later. Call (877) 358-6557 before the plan set is final, and we’ll flag rough-in issues early.
Often, yes. Hard Sunnyvale water clogs the inlet filter on Washlet S350e and C5 seats, which stops heating and spraying. Swapping that filter fixes a surprising number of units. If the control board or heater is dead and the unit is out of support, replacing the seat is the honest answer. We’ll tell you which one applies and quote both options.
We service the Drake two-piece line (CST743 and CST776), Ultramax II one-piece, Washlet integrated seats in the S350e and C5 class, and EcoPower 1.28 gpf models. If you have an older Toto that’s still running, we can usually work with it. The parts that matter are the fill valve, flush tower, and inlet filter, and we keep a range of those in the van for faster Sunnyvale turnaround.
A simple Toto replacement where the rough-in matches and the flange is sound is the least expensive path, often a few hundred dollars for labor and parts. But in the 1950s and 60s ranches that dominate Sunnyvale, the rough-in is frequently 10 inches when the new Toto needs 12, and the slab may need to be opened. That moves the price into remodel territory. The only way to know is to measure. Call (877) 358-6557 for a free estimate, and we’ll be straight about which camp you’re in.
