We’re Sundance Contractors, a licensed general contractor that installs, repairs, and services Toto toilets, Washlets, faucets, and shower systems across Westminster.

Why Westminster Residents Choose Us for Toto Service

Noel Carranza runs our crew, and he grew up at the old Yorba Regional Park while his father framed houses in the hills above it. He learned construction from the slab up. Since then we’ve worked on hundreds of Toto fixtures in Westminster bathrooms, from builder-grade Carolina toilets in 1960s stucco tract homes to wall-hung Neorest builds we coordinated with rear ADU additions.

We know Toto’s fill-valve, flush-tower, and Washlet electronics families by hand, not by manual. That matters because when a Drake starts ghost-flushing or a Washlet inlet solenoid dies in a multi-generational home where the seat runs dozens of cycles a day, we don’t guess. We show up with the right OEM part the first time.

Most of our Westminster Toto work falls under Toto sales & service, which covers the fixture side of the larger remodels we run.

Common Toto Construction Problems We Solve in Westminster

These show up repeatedly in the housing stock around Westminster service area:

• Ghost-flushing Drake fill valves and flush towers. Westminster’s older water lines carry heavy mineral content, especially in 1950s-70s neighborhoods off Bolsa Avenue. The original Toto fill valve in a Drake (CST744 or CST454 series) gets pitted and starts misreading tank level, so the toilet runs or flushes weakly. An OEM replacement fixes it.
• Washlet bidet seat electronics failing at the inlet solenoid or control board. We see this most in multi-generational Vietnamese households where the Washlet runs for grandparents and small children all day, every day. The seat isn’t designed to fail quickly, but constant cycling wears the solenoid contacts faster than a once-a-day household ever would.
• Base leaks from degraded wax rings and closet flanges on slab foundations. Westminster’s postwar homes sit on concrete slabs. When a garage gets converted into an in-law suite, the toilet often gets reset on the old flange, and if that happens two or three times over a decade, the flange cracks and the wax ring fails. The toilet leaks at the base and rots the surrounding tile.
• Chrome and brushed-nickel Toto trim pitting in coastal salt air. Westminster sits close enough to the coast that the salt air plus Orange County’s hard water accelerates pitting on Toto faucet and shower trim. It starts as small dots on the finish and spreads until the trim looks corroded.
• Toilets roughed in wrong during hasty in-law suite additions. When a Westminster garage becomes a bedroom and bath, the rough-in sometimes gets positioned without accounting for slab drain lines or venting. The Toto toilet ends up misaligned, too close to a wall, or venting improperly, so it won’t flush right no matter what parts get swapped.

Toto Service in Westminster: What Local Conditions Mean for Your Equipment

Here’s something we deal with in Westminster that a contractor in a neighboring city like Fountain Valley rarely faces to the same degree. Because so many Westminster garages and rear additions are being converted into in-law suites on tight postwar lots, the resulting new bathroom often shares a slab and drain line with the main house. That means Toto toilet placement, rough-in measurements, and venting have to be coordinated with ADU or junior-ADU setback and parking approvals, not treated as a standalone fixture swap.

On a rear-addition in-law suite off Bolsa Avenue, our crew pulled out a builder-grade toilet and set a Toto Drake two-piece with a fresh wax ring and new closet flange on the shared slab, then added a Washlet seat for the homeowner’s elderly mother. The old fill valve had been ghost-flushing for months. Replacing it with an OEM Toto valve plus a proper flange reset stopped the water waste and the base leak in one visit.

If you’re converting a garage or adding a rear unit, the Toto fixture isn’t just a toilet. It’s part of a larger construction scope that includes plumbing, drainage, and Westminster’s permitting rules. We handle that whole scope.

Toto Models & Products We Service in Westminster

We service the Toto lines you actually have in your home here:

• Toto Drake two-piece toilets (CST744 and CST454 series), including the Drake II with tornado flush
• Toto Ultramax II one-piece toilets with double-cyclone flush
• Toto Neorest and Washlet electronic bidet seats, including the S550e and S500e series
• Toto EcoPower and high-efficiency dual-flush models found in newer remodels

For internal components, fill valves, flush towers, and Washlet control boards, we use genuine Toto OEM parts. Aftermarket clones don’t hold calibration in Toto’s proprietary internals, and you’ll be back in the same spot in six months. For cosmetic trim and standard supply lines, we’ll spec a quality aftermarket option when it saves you money without changing how the fixture performs. When a Toto toilet is over 15 years old and needs a tank rebuild plus a new seat, we quote both repair and replacement so you can decide with real numbers in front of you.

FAQs – Toto Construction in Westminster

My Toto Drake keeps running and ghost-flushing. Is it the flapper or the fill valve, and can you fix it without replacing the toilet?

In almost every case we see in Westminster, it’s the fill valve or the flush tower, not the flapper, and the toilet doesn’t need replacing. Toto Drakes use a proprietary flush-tower seal instead of a traditional flapper, so generic flapper replacements don’t solve it. We replace the fill valve and flush tower with OEM Toto parts and the ghost-flushing stops. Call (877) 752-3951 for a free estimate.

We’re converting our Westminster garage into an in-law suite with a Toto toilet and Washlet. What has to be coordinated beyond the plumbing?

Beyond plumbing, Westminster’s ADU and junior-ADU rules dictate where the bathroom can sit on the lot, how much parking has to remain, and how the drain line ties into the main sewer. On shared slabs, the rough-in has to be set before concrete is poured, and the venting has to tie into the existing roof stack correctly. We coordinate the entire scope, Toto fixture, slab work, permits, and finish plumbing. Call (877) 752-3951 to talk through your garage conversion.

How long do Toto Washlet bidet seats typically last in a busy multi-generational household?

In a busy Westminster household where the Washlet cycles dozens of times daily, the seat electronics usually last 5 to 8 years before the inlet solenoid or control board starts failing. Normal use can double that. We service Washlet S550e and S500e models and replace failed solenoids and control boards with OEM components. Call (877) 752-3951 for a diagnostic visit.

My 1970s Westminster home has a Toto toilet that leaks at the base. Is that the toilet or the floor flange?

On a slab foundation, a base leak is almost always the wax ring or the closet flange beneath the toilet, not the toilet itself. Westminster’s 1950s-70s slabs commonly have cast-iron or older PVC flanges that crack after repeated toilet resets from prior remodels or garage conversions. We reset the toilet with a fresh wax ring and repair or replace the flange. Call (877) 752-3951 and we’ll confirm what’s leaking before quoting the fix.

Can you match a Toto faucet or shower trim finish when we remodel a Westminster bathroom, and will the existing fixtures stay?

Yes. When we remodel a Westminster bathroom, we can match Toto’s existing finish family or swap the trim while keeping the existing valve bodies where they’re still sound, OR replace the full fixture if they’re pitted from salt air and hard water. We handle full Bathroom Remodeling, Walk-In Showers, Shower Remodeling, and Vanities under one contract, so the Toto fixtures get matched to the rest of the room. Call (877) 752-3951 for a free remodel estimate.
