We’ve torn out and rebuilt dozens of Long Beach kitchens and baths around Toto fixtures, so we know exactly how their Washlet seats, one-piece toilets, and high-efficiency flush valves fail in real homes. We are an independent remodeling company - not authorized by Toto - but our install and retrofit experience with their products is local and hands-on. Long Beach’s water is moderately hard and many homes still have original 1950s-1970s plumbing, so Toto Washlet scale and toilet flange issues here show up faster than in softer-water markets. That’s why we scope a toilet flange and shutoff valve inspection into every Toto bathroom job.
Why Trust Rowan Construction Group Long Beach for Your Toto Construction?
Our crews have handled Toto products in Long Beach since we started working here over a decade ago. Grant Rowan, who grew up in Los Angeles and came up through framing, concrete, and finish carpentry at Los Angeles Trade-Technical College, built this company on the principle that you don’t skip the fundamentals and expect a clean result. That applies directly to Toto work: a Washlet seat installed on an unlevel bowl will leak. A Drake toilet set on a rotted flange will rock. We check both before we quote.
We use genuine Toto replacement parts when they are still in production - flush valves, fill valves, tank gaskets, and Washlet nozzles - and turn to quality aftermarket equivalents only for discontinued or obsolete components. Our technicians are background-checked and uniformed; a live person answers our phones 24/7; and every visit includes a documented photo record as standard, not an upgrade. Under Clause 1 of The Haven Standard, your price is written before anyone picks up a tool. Under the 365-Day Done Right Promise, if it is not done right, we make it right.
Common Toto Construction Problems We Fix in Long Beach

- Washlet control panel and pump failure. The S550e, C200, and K300 seats - plus older 300-series units - eventually quit heating water or responding to the remote. In Long Beach, hard-water scale clogs the nozzles and calcifies the pump chamber. A Belmont Heights homeowner called us about a Toto Washlet S550e that quit heating water and would not respond to the remote - the control board and pump had failed in a 9-year-old unit. Since Toto no longer stocked that board, we replaced the seat with a current Washlet model and re-sealed the Toto Drake toilet behind it while we were in the bathroom. The customer kept the original Drake bowl, which still flushed fine after a new fill valve and flapper.
- Drake and Ultramax flush valve seal wear. The CST744, CST454, and one-piece Ultramax toilets use a flapperless tower flush valve that seals with a rubber gasket. Moderately hard Long Beach water stiffens that gasket in 5-7 years. The toilet runs phantom cycles or delivers a weak flush. We replace with the genuine Toto valve assembly, check the fill valve while we’re in the tank, and test the shutoff for corrosion.
- One-piece toilet tank-to-bowl gasket leaks. Ultramax and Vespin one-piece toilets have a sealed joint between tank and bowl that uses a proprietary gasket. After 10-15 years, especially in bathrooms with poor ventilation, the gasket dries and weeps at the base. We usually find this during a remodel tear-out. The fix is a full gasket replacement, but if the bowl is already out for flooring or tile work, we quote both options.
- Discontinued electronic parts on aged units. Washlet seats and integrated toilets from 10-plus years ago often have control boards, sensors, or power supplies that Toto no longer manufactures. We check part availability before we quote a repair. If the component is obsolete, we tell you honestly and price a current replacement unit.
- Slow-fill or no-fill from corroded supply connections. Original 1950s-1970s angle stops and supply lines in Long Beach homes seize, drip, or restrict flow to the fill valve. The fill valve itself can clog with scale. We replace the angle stop, supply line, and fill valve as a system when we find this, because fixing one and leaving the other is a callback waiting to happen.

AfterToto Parts & Our Repair-vs-Replace Approach
We stock genuine Toto flush valves, fill valves, tank gaskets, and Washlet nozzles on our Long Beach trucks for same-day repair when the part is still in production. For discontinued components, we source quality aftermarket equivalents that match Toto’s flow and pressure specs. Our rule is simple: if a Toto fixture is under 10 years old with a single failed component, we repair. If it’s 10-plus years old with multiple electronic failures, or if the porcelain is cracked, we recommend replacement and quote both a direct swap and a full remodel option. No work proceeds on either path until you sign a written change order. Call (424) 567-7009 for an exact quote - estimates are free.
Our Toto Service Process - Step by Step

- 1
Diagnosis. We inspect the Toto fixture, test water pressure and temperature at the shutoff, and photograph the condition of the flange, supply line, and surrounding substrate. For Washlet seats, we test the control board, pump, and heating element.
- 2
Repair or install. We use genuine Toto parts when available, quality aftermarket when not. For remodels, we set the new Toto toilet or Washlet on a fresh wax ring or foam seal, level it to the finished floor, and torque the flange bolts to spec.
- 3
Test. We cycle the flush 10 times, check for leaks at the base and supply, run the Washlet through all functions, and verify the heated seat and dryer reach temperature.
- 4
Warranty documentation. You receive a written scope, the documented photo record, and the 365-Day Done Right Promise in writing. If it is not done right, we make it right.

FAQs - Toto Construction Service in Long Beach
Is Rowan Construction Group Long Beach authorized by Toto?
No. We are an independent Toto service provider, not affiliated with or authorized by Toto USA. We install and repair Toto products based on hands-on field experience, manufacturer specifications, and genuine or compatible replacement parts.
Do you use genuine Toto/OEM parts?
Yes, when the part is still in production. We use genuine Toto flush valves, fill valves, tank gaskets, and Washlet nozzles for repairs. For discontinued or obsolete components, we use quality aftermarket equivalents that match Toto’s flow and pressure specifications.
How long does Toto service take?
Most standalone Toto repairs - a flush valve replacement, fill valve swap, or Washlet seat install - take 1-2 hours. Full bathroom remodels with Toto fixtures run 2-4 weeks depending on scope. We give you a written timeline with the written price before work starts.
What Toto models/series do you cover?
We service and install Toto Washlet seats (S550e, C200, K300, and older 300-series), Drake and Eco Drake toilets (CST744, CST454), Ultramax and Vespin one-piece toilets, and Promenade and Guinevere toilet and sink lines. If you own a model not listed, call (424) 567-7009 and we’ll confirm compatibility.
Will service void my Toto warranty?
Toto’s warranty covers defects in manufacturing, not installation or wear-related repair. Using an independent service provider does not automatically void a valid manufacturing warranty, but damage caused by improper installation or non-OEM parts may not be covered. We use genuine Toto parts when available and document our work with photos to protect your claim if a defect arises.

Can you repair a Toto Washlet that stopped heating water, or do we need a new one?
It depends on age and part availability. If the unit is under 10 years old and Toto still stocks the control board or heating element, we repair. If the board is discontinued - common on 9-plus-year-old S550e and 300-series seats - replacement is usually the better value. We check part numbers before we quote. Call (424) 567-7009 for an exact quote - estimates are free.
Why does my Toto Drake toilet keep running or refill slowly?
The flapperless tower flush valve seal has likely stiffened from hard-water exposure, or the fill valve is clogged with scale. Both are routine on Long Beach’s moderately hard water after 5-7 years. We replace the valve assembly, check the fill valve, and inspect the shutoff for corrosion. Call (424) 567-7009 for an exact quote - estimates are free.
Will a new Toto toilet or Washlet fit my existing bathroom rough-in?
Most Toto toilets use a standard 12-inch rough-in, but some Drake and Ultramax models also come in 10-inch and 14-inch versions. We measure your rough-in, flange height, and finished floor level before we quote to avoid a return trip. Washlet seats fit most elongated bowls but require a nearby GFCI outlet. Call (424) 567-7009 for an exact quote - estimates are free.
Do you install Toto toilets and Washlets as part of a full bathroom remodel?
Yes. Toto fixtures are a regular specification in our Long Beach bathroom remodels. We sequence the plumbing rough-in, tile or flooring, and fixture set to protect the finish. The price is written before anyone picks up a tool, and no change proceeds without a signed change order. Call (424) 567-7009 for an exact quote - estimates are free.
Is it worth replacing a 15-year-old Toto toilet during a remodel instead of repairing it?
Usually yes. At 15 years, the fill valve, flush valve, and tank gasket are all near end of life, and water efficiency standards have improved significantly. We quote both a direct replacement and a repair, but most Long Beach homeowners choose replacement during a remodel to avoid opening the wall again in three years. Call (424) 567-7009 for an exact quote - estimates are free.
