Boxabl Bathroom Remodeling: The Miami Owner’s Guide
Boxabl bathroom remodeling in Miami typically runs $10,620 – $33,040 installed, depending on whether you’re refreshing a compact Casita bath or reworking the plumbing layout in a larger model. We stock Boxabl-compatible shower pans, wall panels, vanities, and fixtures, and we can usually start within two weeks of your written estimate. Most owners call us after noticing water staining at the base of the shower surround, a vanity that’s swelled at the edges, or tile that’s cracked along the folding-wall seam where the home was joined.
Trevor Nash has walked through enough Boxabl units in Coconut Grove and Kendall to know exactly where factory bathroom components tend to fail first in our climate. Give you a number first, then pick up the tools.
Which Boxabl Models This Applies To
We handle bathroom work across the Boxabl product line, including the Casita (the 20×20 accessory dwelling unit most common in Miami backyards) and larger custom configurations that pair multiple modules. Boxabl bathrooms are built around a factory-installed wet-wall system: the plumbing, shower valve, and drain are pre-packed into a single wall chassis, which means a bathroom remodel here is less about tearing out drywall and more about knowing which panels and fixtures are compatible with that factory geometry.
The gotcha for Miami owners: Boxabl ships with 48-inch shower pans and 24-inch vanities as standard, and the wall panels are a fiberglass-reinforced composite, not ceramic tile. If you’ve been quoting standard residential bathroom fixtures, the numbers won’t transfer. We identify your exact module generation by the serial plate inside the bathroom access panel, then match components accordingly. For most Casita modules built after the 2023 production run, genuine factory shower pans and surrounds are available, but quality aftermarket equivalents from Kohler and Moen often fit with minor trim work and carry their own warranties alongside ours.
We’re an independent remodeling company, not a Boxabl dealership or authorized service center. That independence means we recommend whatever part actually solves the problem, whether it’s OEM or a better-built standard fixture.

Signs Your Boxabl Bathroom Remodeling Is Failing
- Soft spots at the shower pan edges. The factory pan is a single molded piece, but Miami’s humidity plus the slight flex of a transported module can cause the pan flange to separate from the wall panels. Water gets behind the composite and sits, softening the subfloor beneath.
- Vanity base swelling or discoloring at the bottom corners. Boxabl factory vanities are engineered for weight savings, not decades of moisture. Once the laminate edges delaminate, water creeps into the particleboard core and the cabinet loses structural integrity quickly.
- Cracked wall panels near the fold joints. Boxabl modules hinge open on delivery, and the bathroom wall panels bridge that hinge line. Over time, even a few millimeters of settlement creases the composite, and hairline cracks let shower spray seep into the wall cavity.
- Positive-trending musty odor after showers. That smell is trapped moisture somewhere it shouldn’t be. In a Miami summer, a small leak behind a Boxabl wall panel goes bad fast, and mold starts colonizing within days.
- Faucet or shower valve pressure drops. The factory-installed PEX runs have crimped fittings that can deteriorate after sustained exposure to Florida’s mineral-heavy water. If pressure fluctuates between hot and cold, the cartridge or the crimp is failing.

AfterReplacement Cost & What’s Included
Bathroom remodeling for a Boxabl in Miami runs $10,620 – $33,040 installed. The spread comes down to scope: a small bathroom remodel (shower surround replacement, new vanity, new toilet, re-caulk, paint) lands between $5,900 – $14,160. A full rework that includes moving the wet wall, new plumbing runs, custom cabinetry, and a walk-in shower with glass enclosure will push toward the top of the range.
Every Penhallow estimate includes the material cost, the labor, the tear-out and haul-away, and a written line-item breakdown. We source vanities from KraftMaid and Wellborn when the factory unit is beyond saving, and install Cambria or Silestone countertops with their own manufacturer warranties layered over our workmanship guarantee. The price we hand you before work starts is the price on the invoice. No change orders unless you ask for something different mid-project.
Here’s how the cost typically splits on a mid-range Boxabl bathroom refresh in Miami:
- Shower surround or pan replacement: $3,540 – $7,080 depending on whether we keep the existing valve or replumb
- Vanity replacement (24-inch to 30-inch): $945 – $3,540 including countertop and sink
- Flooring (waterproof vinyl plank or tile): $1,180 – $3,540 for a typical Casita bath footprint
- Labor, demo, haul-away: $2,360 – $5,900 depending on access and the condition of what’s underneath
DIY or Call Us?
You can safely handle a few things on your own: re-caulking the shower seams with silicone, swapping a showerhead, tightening a loose faucet handle. From there, Boxabl-specific work gets risky fast. The wet wall contains the shower valve assembly under constant line pressure, and cutting into the wrong spot means a flooded bathroom and a warranty that no longer applies to the module’s original plumbing.
If your shower pan has separated from the wall or the vanity is swelling, the damage underneath is almost always worse than what you can see. We open up Boxabl bathrooms in Miami regularly, and the honest truth is that someone has usually tried a patch job first, which gives the water more time to travel. Call (850) 988-7559 for a free estimate and we’ll tell you straight what needs doing and what it costs before anything gets touched.
FAQs
With proper waterproofing and quality materials, a remodeled Boxabl bathroom in Miami should last 15 – 25 years before needing meaningful work again. The factory components often fare worse in our humidity, which is why we rebuild with moisture-rated backer board and marine-grade sealants rather than repeating the original install methods.
Sometimes, but not often. If the pan is cracked or the flange has separated, a patch is a temporary fix that hides the real leak. We’ll give you an honest assessment and a written price for repair versus replacement, with no pressure either way. Call (850) 988-7559 and we’ll take a look.
Most Boxabl bathroom remodels in Miami wrap up in 2 – 3 working days for a shower and vanity replacement, or 5 – 7 days for a full gut-and-rebuild. You’ll get a defined arrival window and a written schedule before we start, and you’ll know exactly who will be in your home each day.
We keep common Boxabl-compatible shower pans, wall panel kits, faucets, and 24-inch vanities in our Miami inventory, sourced through our trade suppliers and brands like Kohler, Moen, and KraftMaid. If your module needs a factory-specific piece, we’ll order it and give you a firm install date before we schedule.
