Toto Home Additions & ADU: The West Palm Beach Owner’s Guide
Home additions and ADU construction in West Palm Beach typically run $45,000 to $130,000 for a Bradford Remodeling project, depending on square footage, foundation work, and whether the structure ties into the existing roofline or stands separate. We handle the full scope: permits, slab or crawlspace, rough-in, Toto fixture installation, and final inspection. Most homeowners who call us have already discovered the hard truth about South Florida additions: the vapor barrier, hurricane strapping, and drainage details matter more than the drywall. Miss those, and you’ll be chasing problems for the life of the structure.
If you’ve got a Toto product specified for your addition or ADU, you’re already making the same kind of decision we make with our builds: buy the thing that performs, not the thing that’s cheapest. The toilet, tub, or washlet is a small line item in a six-figure project, but it’s the one fixture you’ll interact with every single day. Get it right the first time.
Which Toto Models This Applies To
We install the full Toto range in West Palm Beach additions, but there’s a compatibility reality most owners don’t learn until the fixtures arrive. Toto’s entry-level Drake and Entrada lines use the standard 12-inch rough-in, which is simple enough. Move up to the Neorest or Aquia IV, and you’re looking at skirted bowls that don’t play well with standard wax rings and bolt patterns. The Aquia’s dual-flush carrier wants a specific flush valve assembly, and the Neorest requires a dedicated GFCI circuit within reach of the bowl. If you’re building an ADU around a Neorest, the electrical rough-in has to be in the wall before drywall goes up.
Our advice: confirm the exact model number of every Toto fixture before the slab is poured. The model number is stamped inside the tank or on the underside of the bowl lip. For OEM versus aftermarket parts down the road, we stock genuine Toto internals on the truck. The trip levers, fill valves, and flappers are worth buying OEM, because Toto’s flush valve dimensions are not universal. A generic flapper from a big-box store will fit, mostly, and leak, eventually. In Florida’s hard water, that eventual failure comes faster than you think.
Styles & brands we work with
Signs Your Toto Home Additions & ADU Is Failing
- Water seeping at the base of the toilet after a flush. This usually means the wax ring has failed or the flange is below finished floor height. In additions, we see this when the tile setter built the floor up around the flange instead of raising the flange first. The fix means pulling the toilet and resetting the flange.
- The toilet rocks or shifts under weight. The floor around the flange is settling or the subfloor wasn’t reinforced for the fixture. West Palm Beach’s sandy soil moves, and unless the slab was compacted properly before the pour, you’ll get movement. Rocking compromises the seal and eventually cracks the porcelain.
- The washlet cycles on and off by itself. Toto’s electronic features are sensitive to voltage fluctuation and moisture intrusion. In an ADU on a shared panel, the surge from an air conditioner compressor can confuse the sensor board. We see this enough that we now recommend a dedicated circuit for any Toto with a heated seat.
- The fill valve runs continually or hisses after refill. Sediment from West Palm Beach’s municipal water supply works its way into the valve seal. It’s a $30 part and a 30-minute swap, but you ignore it for long enough and the constant flow wears the flapper too. Then it’s a full rebuild instead of a valve.
- The flush is weak or takes two attempts. The jet holes under the rim are clogged with mineral scale, or the water level in the tank is set too low. Toto’s G-Max flush system depends on the proper water volume to create the siphon. Cut the volume with a misadjusted float and the flush goes soft.

AfterReplacement Cost & What’s Included
For a Toto fixture repair or replacement within a home addition or ADU in West Palm Beach, you’re usually looking at $200 to $600 on top of the fixture itself, depending on what failed and how deep the repair goes. A fill valve swap is at the low end. Pulling a skirted toilet to address a flange issue at the high end. If the problem is structural, meaning the subfloor or slab under the fixture needs work, that’s a different conversation, and we’ll put the full scope in writing before touching it.
The $45,000 to $130,000 range for a home addition reflects the real spread in this market. A 300-square-foot bump-out with a single bathroom runs the low end. A 1,200-square-foot ADU with a full kitchen, bath, and separate electrical service runs the high end. What drives the variance: site preparation, soil conditions, existing roof tie-in complexity, and your fixture package. Bradford Remodeling gives you a written price before any work starts. That price includes the parts, the labor, the permit coordination, and the cleanup. If the number on paper doesn’t match the number at the end, that’s our problem. It won’t happen.
DIY or Call Us?
There’s no dangerous high-tension work in swapping a Toto toilet internals kit, so honest DIY work is perfectly reasonable if you’re handy. You can check the model number, confirm the water level in the tank, and clear jet holes with a bit of vinegar and a small brush. Don’t start tearing out tile or cutting into the subfloor, though. Once you get below the surface in a Florida addition, you run into the moisture barrier, the anchoring system, and in some cases, electrical for the washlet. Cut the wrong thing and you’ve turned a $250 parts job into a $4,000 floor repair.

FAQs
A well-maintained Toto toilet will last 20 to 25 years in Florida’s climate, though internal components like the fill valve and flapper usually need replacement every 4 to 6 years due to hard water mineral buildup. The porcelain itself rarely fails unless it’s struck or improperly installed. Call (728) 203-9809 for an exact quote on a rebuild, and we’ll give you the straight number.
Yes, in most cases a failing Toto fixture just needs its internal components rebuilt: fill valve, flapper, flush valve, and sometimes the trip lever. We stock these genuine Toto parts on our trucks, so repair is typically a single-visit job. If the failure is at the flange or subfloor level, replacement work may be necessary, and we’ll show you exactly what we found before we do anything.
In an active addition or ADU build, the rough-in to finish fixture installation spans several weeks because it’s sequenced with plumbing, electrical, and finish work. In an existing structure, a full Toto toilet replacement with flange inspection takes about 2 to 3 hours. Call (728) 203-9809 and we’ll tell you how long your specific situation will take.
We keep genuine Toto fill valves, flappers, trip levers, and flush valve assemblies on the truck for immediate service in West Palm Beach and nearby areas. We also work with KraftMaid, Cambria, and Silestone for the broader remodel scope, but Toto-specific repairs use OEM internals, not generic substitutes. If it’s not on the truck, we’ll have it in hand before we schedule the visit.
