Toto Home Additions & ADU: The Fort Lauderdale Owner’s Guide
Planning a home addition or ADU in Fort Lauderdale with Toto fixtures specified means getting the plumbing rough-in and finish details right from the first day of framing. A full addition or accessory dwelling unit typically runs $45,000 – $130,000 in Fort Lauderdale when we handle the build, and Toto toilets, lavatories, and shower components are standard in our specs because they hold up to South Florida humidity and hard water better than most. Most owners reach out to us after a previous contractor installed Toto fixtures poorly or a DIY addition left them with a leaking flange, a rocking toilet, or a shower valve that never quite worked right.
Penhallow Remodeling Fort Lauderdale is an independent general contractor. We install and service Toto products, but we are not affiliated with Toto. If you are mid-project or staring at a failed rough-in, this page tells you what to check, what it costs, and when to call us.
Which Toto Models This Applies To
Toto’s lineup for additions and ADUs spans the Drake, Ultramax, Aquia, and Nexus toilet lines, plus the Promenade and Legato lavatories and a range of shower and tub fixtures. The compatibility gotcha most Fort Lauderdale owners hit is the rough-in measurement. Most Toto toilets need a 12-inch rough-in, but the Aquia and some skirted models need a precise 10-inch or 14-inch rough-in depending on the adapter. If the plumber sets the flange at the wrong distance, the toilet simply will not sit flush against the wall.
Another South Florida-specific detail: Toto’s G-Max and Tornado Flush systems are engineered for 1.6 and 1.28 gallons per flush. Fort Lauderdale’s older plumbing in neighborhoods like Victoria Park or Sailboat Bend sometimes delivers inconsistent water pressure, which causes weak flushing that owners blame on the toilet when the real issue is a corroded supply line or an undersized valve. We check the supply before we replace the fixture. As for OEM versus aftermarket, we stock genuine Toto fill valves, flappers, and flush tower assemblies, because aftermarket flappers on a Toto tower flush are a false economy. They fit loose, flush poorly, and fail again within a season.
Styles & brands we work with
Signs Your Toto Home Additions & ADU Is Failing
- Wobble or rock at the base. The flange sits too high or the subfloor around it has swollen from humidity. A rocking Toto compresses the wax ring over time and eventually leaks into the subfloor. This is common in Fort Lauderdale additions where the slab or wood subfloor was never leveled before tile went down.
- Sewer smell in the new room. That is a failed wax ring or a flange that dropped below the finished floor. Toto bowls seal tightly, but no fixture can overcome a flange set a half-inch too low.
- Ghost flushing or water trickling into the bowl. The fill valve or the flush tower seal is worn. On Toto towers, the rubber seal degrades and the tank slowly refills at random intervals. It wastes water and drives up the Fort Lauderdale utility bill.
- Weak or incomplete flush. The rim jets are clogged with mineral scale from Florida hard water, or the supply line is undersized for the Tornado Flush. We see this constantly in ADUs plumbed with half-inch lines where three-quarter-inch was specified.
- Condensation on the tank. Fort Lauderdale’s humidity hits uninsulated cold-water tanks hard. Toto’s insulated tank liners help, but a non-insulated tank in an unconditioned ADU will sweat and damage the floor around it.

AfterReplacement Cost & What’s Included
Within a full home addition or ADU in Fort Lauderdale, the plumbing fixture package including Toto toilets, lavatories, and shower components accounts for a meaningful slice of the $45,000 – $130,000 project total. When we replace a Toto toilet alone, installed cost in Fort Lauderdale runs $500 – $1,800 depending on the model and what we find under it. A complete bathroom rough-in for a new addition, with Toto fixtures, supply lines, DWV piping, and a shower valve, runs roughly $4,500 – $12,000 when pulled out as its own scope.
You get a written price before we start. That number includes the fixture, the wax ring or flange repair, supply line, shutoff, and disposal of the old unit. If we open the wall and find the flange is rotted or the subfloor is spongy, we will show you, tell you the added cost in plain numbers, and get your sign-off before we proceed. No surprises on the invoice. The work is covered by our 365-Day Done Right Promise: if the Toto install fails inside that year, we come back and fix it at no charge.
DIY or Call Us?
Replacing a Toto toilet or swapping a fill valve is not a high-tension job, but it goes wrong in Fort Lauderdale more often than it should. You can safely check the water supply, confirm the shutoff works, and wipe down the rim jets with a mild descaler. What you should not do is lift a Toto skirted bowl off a failing flange and guess. If the flange is cracked, the subfloor is wet, or the rough-in is wrong, you will damage the new fixture, the tile, or both. We have repaired enough DIY ADU bathrooms in Fort Lauderdale to know that the $200 saved on a plumber often becomes a $2,000 subfloor repair.
If you want the fixture installed to Toto spec, with the flange set at the right height and the supply line sized correctly, call us at (754) 551-2922. Trevor Nash and the team will look at the room, measure the rough-in, and give you a written price before touching a tool.
FAQs
A properly installed Toto toilet lasts 20 years or more, and the porcelain bowl itself can easily outlive the bathroom. The parts that wear are the fill valve, flapper or flush tower seal, and the wax ring, which typically need attention every 5 to 8 years in Fort Lauderdale due to hard water scale and humidity-related flange corrosion. If you are pricing a replacement, call (754) 551-2922 and we will tell you whether you need a $30 seal or a new fixture.
Yes, most Toto failures are repairable. A running toilet is usually a $15 – $40 fill valve or flush tower seal. A rocking toilet is a flange and wax ring repair, not a new fixture. We only recommend replacement when the bowl is cracked, the model is discontinued with no parts availability, or the rough-in is so far off that retrofitting costs more than a new unit. Call (754) 551-2922 and we will assess it on a free estimate visit.
A straightforward Toto swap in Fort Lauderdale takes 2 to 3 hours from shutting off the water to the final flush test. If the flange needs repair or the subfloor requires patching, figure on a half day. We set a defined arrival window, show up on time, and leave the bathroom cleaner than we found it.
Yes. Our Fort Lauderdale technicians carry genuine Toto fill valves, flappers, flush tower seals, and wax rings on every service truck. If you need a part for a Toto Drake, Ultramax, or Aquia, we most likely have it with us on the first visit. We also keep parts for KraftMaid, Cambria, and Silestone products when the job involves cabinetry or countertops tied into the addition.
If your Toto addition or ADU needs a repair in Fort Lauderdale, call (754) 551-2922. Tell me what you need, I’ll tell you what it costs, then we’ll get it done. Written price, written guarantee, and a real person on the phone.
