Toto Home Additions & ADU Nationwide

Toto Home Additions & ADU: The West Palm Beach Owner’s Guide

If you’re planning a home addition or ADU in West Palm Beach and want Toto fixtures specified into the build, we handle that from rough-in to trim-out. A full home addition here typically lands between $45,000 and $130,000, while an ADU runs $90,000 to $220,000, depending on square footage, foundation work, and how many Toto pieces you’re putting in. Most owners reach out after a builder quotes them a number without naming a single fixture brand, leaving them guessing whether they’re paying for Kohler-level quality or whatever was on the shelf at the supply house. You find yourself staring at a line item that says “bathroom fixtures” and wondering why nobody will tell you the brand. That’s where we start differently: the Toto models go on the written scope by name before we ever break ground.

Which Toto Models This Applies To

The short answer is every Toto line that fits a residential rough-in. We regularly specify the Drake and Drake II for their flush consistency and the fact that parts remain available years after installation. The Ultramax and Nexus lines show up often in ADU builds where clients want a one-piece toilet that doesn’t collect dust in the seam between tank and bowl. For wall-hung applications, the Aquia and Carlyle series matter, but here’s the compatibility gotcha most people don’t learn until the tile is up: wall-hung Toto models require an in-wall carrier system, and the carrier needs to be specified before the wall is closed. If you’re pricing a Toto wall-hung toilet after drywall, you’re also pricing a wall opening and carrier retrofit. In West Palm Beach, the other spec detail that catches people is the water supply rough-in height. Most Toto floor-mounted models want the supply stub at a specific offset from center, typically 6 to 8 inches depending on series, and if the slab or wall was roughed for a different brand’s measurements, the plumber is moving a pipe. We check these dimensions against the actual Toto spec sheet before the concrete goes in, not after.

Signs Your Toto Home Additions & ADU Plan Is Going Wrong

• The quote doesn’t name the fixture brand. A line item that says “toilet” with no manufacturer means the builder is pricing whatever the supply house has in stock that week. You lose the Toto warranty tracking and the ability to verify the model before it’s installed.
• The rough-in dimensions weren’t checked against the spec sheet. Toto’s spec drawings are specific about supply location, drain center, and clearance behind the bowl. If the plumbing went in first and fixtures were an afterthought, you’ll pay to move pipes later.
• Wall-hung Toto products are selected after framing inspection. The in-wall carrier has structural requirements that the framer needs to account for. Finding out after inspection means opening a finished wall.
• The ADU scope doesn’t include a fixture schedule by room. This is the three-page list that tells the plumber exactly which Toto model goes in which bathroom, with part numbers. Without it, substitutions happen quietly.
• The builder won’t put the Toto SKU in writing. If the specific model number isn’t in the contract, you don’t have a Toto product. You have a promise, and promises don’t carry a manufacturer warranty.

Replacement Cost & What’s Included

In West Palm Beach, a home addition with one new bathroom runs $45,000 to $130,000. An ADU with a full bath and kitchen runs $90,000 to $220,000. Toto fixtures themselves are a modest slice of that number, a Drake II typically runs a few hundred dollars at supply, but the labor to rough-in, set, and trim out each piece lands in the $800 to $2,500 range depending on access and whether we’re moving existing plumbing. What drives your total is square footage, slab work, roof ties, and how many wet walls you’re adding. We write every job with a fixed scope: labor itemized by task, Toto model numbers listed for each fixture, and a firm start and end window. That price doesn’t change once the crew arrives unless you change the scope, and if you do, the change order is written and signed before the extra work happens. The 365-Day Done Right Promise covers the complete project, if something isn’t done right after we finish, we come back and make it right. That’s the whole promise.

DIY or Call Us?

You can absolutely research Toto models, download spec sheets, and decide which fixtures you want before a contractor ever shows up. That’s useful work, and we’ll happily build from your list. What you shouldn’t do is rough in plumbing yourself, hang an in-wall carrier, or pour a slab for an ADU without structural and code review. Wrong rough-in dimensions for a Toto wall-hung unit mean tile removal and pipe relocation, which costs far more than getting it right the first time. West Palm Beach also has wind-load requirements for any addition or ADU structure, and the permit office will flag unpermitted work on inspection. If you’re at the point where you want real numbers with Toto model numbers in writing, call (728) 203-3270 and ask for Graham. We’ll walk the site, measure what’s there, and hand you a written scope you can keep.
