Boxabl Bathroom Remodeling: The West Palm Beach Owner’s Guide

Boxabl bathroom remodeling in West Palm Beach typically runs $9,000-$28,000 for a full replacement, with most Boxabl owners in the $12,000-$18,000 range for a mid-grade update using Kohler or Toto fixtures on a Casita or similar accessory dwelling unit. We stock Boxabl-compatible plumbing rough-in kits, moisture-rated backer board, and compact-fixture assemblies sized for the 19.5-foot module width, and we can usually start within two weeks of a signed quote. Most owners realize their Boxabl bathroom needs attention when the compact drain configuration starts backing up, the factory shower pan cracks along the seam line, or the original fixtures begin corroding from West Palm Beach’s mineral-heavy municipal water.

Which Boxabl Models This Applies To

We’ve worked on the Casita, the Boxabl Accessory Dwelling Unit line, and the early pilot units shipped to Florida between 2021 and 2024. The identifying mark is usually a metal data plate on the electrical panel door or a stamped model suffix on the bathroom vent housing - “CAS-375” or similar. The critical compatibility issue is the 36-inch rough-in depth; standard residential vanities bottom out at 21 inches and won’t clear the Casita’s integrated plumbing chase without modification.

OEM Boxabl fixtures are sourced through their Las Vegas parts desk, with lead times we’ve seen stretch to six weeks. We typically spec Kohler Cimarron or Toto Drake II compact elongated bowls, paired with wall-hung vanities from KraftMaid’s Metro line cut to 18-inch depth. For countertops, we quote Cambria or Silestone in their thinner 2-centimeter profiles to save weight on the module floor. The decision between OEM and aftermarket comes down to timeline: if you’re renting the unit or need it income-ready, the aftermarket route cuts three to four weeks off the job.

Signs Your Boxabl Bathroom Remodeling Is Failing

• Shower pan cracks at the drain seam. The factory fiberglass pan in early Casitas flexes more than code-specified acrylic alternatives, and the West Palm Beach humidity cycle - 90 percent mornings dropping to 60 percent by afternoon - accelerates the stress cracking. We replace with a Schluter-Kerdi bonded membrane system that moves with the module.
• Vanity cabinet swelling at the toe kick. The original particleboard boxes don’t survive the first plumbing leak in Florida’s climate. We see this most often in units near the Intracoastal where salt air compounds the moisture load. Upgraded plywood or KraftMaid’s all-ply construction solves it.
• Fixture corrosion on chrome-plated brass. West Palm Beach’s water runs 7.5 to 8.2 pH with elevated calcium; the thin factory plating fails inside 18 months. We spec brass-body Kohler or Toto valves with physical vapor deposition finishes rated for 500-plus hours salt spray.
• Exhaust fan noise without air movement. The compact 50-CFM unit spec’d for the Casita bathroom can’t handle the latent load of a Florida shower. Condensation migrates into the wall cavity and breeds mold on the paper-faced backer board. We upsize to 80 CFM with a humidistat control.
• Tile grout crumbling at the shower curb. Factory installation used standard sanded grout without an expansion joint; the module’s steel frame transmits more movement than stick-built framing. We remove to substrate and reinstall with epoxy grout and silicone movement joints at changes of plane.

Replacement Cost & What’s Included

The spread depends on three factors: whether we’re working within the existing module footprint or reconfiguring the wet wall, the fixture tier you select, and what we find when we open the walls. In West Palm Beach, we regularly discover the original builder used paper-faced greenboard behind tile - a code violation since 2006 that requires full gut-and-replace of the shower surround. Under Clause 1 of the Haven Standard, your written quote includes a line-item allowance for substrate replacement; if we open the wall and it’s sound, the credit comes back to you. Every remodel carries our 365-Day Done Right Promise and a documented photo record of pre-existing conditions, demolition, and final finish.

DIY or Call Us?

There’s a safe middle ground. An owner can confirm the model suffix from the data plate, photograph the fixture tags, and measure the rough-in depth from the finished wall to the center of the drain - that’s information we need anyway, and it saves a trip charge. What goes wrong fast is the wet work. The Casita’s steel frame grounds differently than wood framing; mixing valve bonding, GFCI protection on the dedicated bathroom circuit, and the compact drain configuration with its proprietary offset flange all require permits and inspection in Palm Beach County. We’ve been called in after three DIY attempts on Flagler Drive alone, each one costing more to undo than our original quote. If you’re pricing the job, call (561) 475-3903 and we’ll review your measurements by text; if you’re ready to move, we’ll schedule the site visit and have your written price before anyone picks up a tool.
