Toto Construction in Miami, FL | Rowan Construction Group Miami
We provide independent Toto toilet, bidet, and washlet service across Miami, with OEM-compatible parts stocked locally for same-day repairs on most Drake, Ultramax, and Washlet models. What sets our Toto work apart in Miami is our fluency with Miami-Dade’s Notice of Acceptance requirements - the product-approval layer that can turn a simple Bathroom Remodeling - Miami fixture swap into a permitting puzzle no out-of-state contractor expects. Call (786) 321-4970 to schedule your free estimate.
Why Miami Residents Choose Us for Toto Service
Grant Rowan learned the trade at Los Angeles Trade-Technical College, then spent over a decade running crews in South Florida - from gut renovations in Coconut Grove to new commercial builds across Miami-Dade. That background means we don’t guess at why a Toto Washlet board failed after a storm surge; we’ve traced the corrosion pattern before.
We stock genuine Toto OEM fill valves, flappers, gaskets, and Washlet control boards at our Miami warehouse. When a part is discontinued, we use quality aftermarket - never a mystery brand - and we tell you which it is before we install it. Our independence from Toto USA lets us repair what you own instead of pushing a replacement you don’t need.
Every visit includes a documented photo record as standard. You’ll see what we found, what we did, and what we recommend next - no verbal promises, no handwritten notes that disappear. Under Clause 1 of The Haven Standard, the price is written before anyone starts. Measure twice, write it down, then build it.
Common Toto Construction Problems We Solve in Miami

- Gasket and flapper failure on Drake and Ultramax flush towers. Miami’s salt-air environment dries out rubber faster than inland climates. We see phantom running and weak flushes in homes from Little Havana to Miami Beach where the flapper has hardened in eighteen months instead of five years.
- Electronic Washlet control boards and seat sensors corroding or shorting. Coastal humidity plus power surges during hurricane season fry S300, S500, and S550e boards. Our techs carry replacement OEM boards and can bench-test the seat sensor harness on site.
- Fill valve and supply-line mineral scale from Miami-Dade’s hard water. The calcium buildup restricts refill flow, causing intermittent or incomplete flushes. We descale what we can and replace what we can’t - always with a written line item before we start.
- UV degradation of plastic hinges and seats. Older Art Deco-era bathrooms in Miami Beach and MiMo districts often have poor ventilation and windows that bake fixtures in afternoon sun. We specify UV-stabilized replacement seats when the original cracks.
- Storm-surge electrical damage to bidet outlets and GFCI circuits. Miami’s wet-season lightning finds the path of least resistance. We test the full circuit, not just the unit, because a new board will fry again if the outlet ground is compromised.

AfterToto Service in Miami: What Local Conditions Mean for Your Equipment
In Miami-Dade, a bathroom fixture swap that touches the water supply or drain can trigger a permit inspection where the inspector checks for a valid Miami-Dade County Notice of Acceptance on any new impact glazing or exterior door. Even a Toto toilet replacement in a Kitchen Remodeling in Miami bathroom with a window often requires that window to carry an unexpired NOA - a paperwork trap that doesn’t exist in Orlando or Tampa. We’ve seen out-of-state contractors get red-tagged at rough inspection because they assumed a Florida-rated window was sufficient. It isn’t here. Miami sits within the High-Velocity Hurricane Zone, the strictest construction standard in the US, and our inspectors enforce it. When we quote a Toto installation in a pre-1992 home in Allapattah or West Flagler, we check the window NOA status first. If it’s expired or missing, we flag it in the written scope so you’re not surprised by a permit hold six weeks later. That’s the difference between a plumber who installs toilets and a contractor who understands Miami’s layered code environment.
Toto Models & Products We Service in Miami

We work on the full Toto residential line: the Drake CST744 series and its variants, the one-piece Ultramax, the Carlyle and Guinevere skirted designs, and the full Washlet range from the S300 through the S550e. Our Miami warehouse stocks the proprietary fill valves and flush towers that big-box plumbers have to order - the Korky 528MP fill valve for older Drakes, the THU500S flush tower gasket, the S550e control board and seat sensor harness. For discontinued models, we source quality aftermarket from Fluidmaster or Korky, document the substitution in your photo record, and price it below OEM when the performance spec matches. If the porcelain is sound, we repair. Full replacement only makes sense when the bowl or tank is cracked or the electronic unit is beyond economical board-level repair.

FAQs - Toto Construction in Miami
Most Washlet failures are repairable. We replace control boards, seat sensors, heating elements, and water lines with OEM parts; full replacement only makes sense when multiple systems have failed or the unit is physically damaged. Call (786) 321-4970 and we’ll diagnose it on the first visit.
The flapper or flush tower gasket has likely hardened from Miami’s salt-air and humidity, or the fill valve has scale restricting proper shutoff. We carry both parts and can fix it in one trip. Call (786) 321-4970 for an exact quote - estimates are free.
The toilet itself does not need an NOA, but if your bathroom has an impact window or exterior door and the permit inspector flags it during the rough inspection, that window or door must carry a current Miami-Dade NOA. We check this before we submit permits so you’re not delayed.
Yes. The rubber flappers and gaskets dry out and crack faster in Miami’s coastal environment than they do inland. We see this in homes from Key Biscayne to Miami Shores. We specify marine-grade or OEM replacement parts rated for higher humidity exposure.
Most repairs - flapper, fill valve, or flush tower replacement - take under two hours. Washlet board-level repairs may need a second trip if we need to order a specific OEM part, though we stock the common S550e and S500e boards locally. Call (786) 321-4970 to schedule.
