A bathroom remodel in Miami is a waterproofing project disguised as a design project. The humidity that rolls in off Biscayne Bay, the concrete slab construction common to most Miami-Dade housing stock, and the strict HOA rules that govern every condo tower in Brickell and Sunny Isles all conspire to punish bathrooms that were installed without proper substrate prep, membrane application, and movement-tolerant grout systems. We have been remodeling Miami bathrooms for over twenty years and we know exactly what kills them — and how to build them so they last.
Standard mainland bathroom construction practices fail in South Florida. Concrete slabs hold moisture and transmit it through tile when no vapor barrier is installed. Showers that were tiled directly over greenboard or unbonded backer rot from the inside out within five years. Frameless glass installed without seismic-grade hardware shifts under wind-load events. Our team starts every Miami bathroom remodel with comprehensive moisture testing, applies a Schluter-Kerdi or commercial-grade liquid waterproofing membrane on every wet surface, and selects flexible thinset systems engineered for substrate movement.
Our typical scope covers demolition and disposal, substrate inspection and moisture testing, plumbing rough-in coordination (relocating drains, supply lines, valves), full waterproofing of wet zones, tile or stone installation on floors, shower walls, and accent features, vanity fabrication and installation, frameless glass shower enclosures, lighting and ventilation upgrades, finish carpentry, painting, and final fixture set. We work directly with Miami's top slab yards to hand-select marble or quartzite for shower surrounds and vanity tops. Clients often join us at the yard in Doral or Hialeah to approve the exact veining before any cutting begins.
The signature Miami master bathroom in 2026 is the spa-style retreat: a single large-format porcelain slab on the floor, full-height book-matched Calacatta or Carrara marble on the shower walls, a frameless glass enclosure with seismic-rated hinges, and a freestanding sculptural tub. Executing this look is not about taste — it is about logistics. The marble has to be sourced from slabs cut from the same block. The shower curb has to be engineered for zero-threshold entry without compromising drainage. The glass panels have to be tempered, drilled, and aligned to millimeter tolerance. Our crew handles all of this in-house, without subcontractors who do not know our standards.
Every Miami condo building has its own bathroom remodel rules. The Plaza on Brickell requires a complete waterproof pan with 6-inch turned-up edges. Brickell Flatiron demands COIs from every trade with $2M aggregate coverage. Continuum and Apogee enforce 9 am to 5 pm work hours and require freight elevator reservations made 72 hours in advance. We have submitted hundreds of bathroom remodel packages to HOAs across Miami-Dade and we know each building's quirks. Our project manager handles the architectural review, building rules acknowledgment, insurance certificates, parking passes, and elevator coordination — you should not be managing your contractor's paperwork.

"Our Brickell condo needed a full master bathroom renovation and the building has very strict rules. AP Stone handled everything — the HOA paperwork, the freight elevator scheduling, the waterproofing. Not a single complaint from neighbors. The finish is beautiful."

Brickell — Master Bath Renovation
"A previous contractor left my master shower in bad shape — cracked grout, tiles already lifting after 18 months. AP Stone did a proper teardown, installed a full waterproofing membrane, and retiled from scratch with marble. Two years later, not a single issue."
Patricia N.
Coconut Grove — Shower Restoration
"Full guest bath and master bath redo in our Coral Gables home. Book-matched Calacatta in the master and a freestanding tub on a porcelain slab floor. Five weeks start to finish, exactly what they quoted. The marble veining is breathtaking."

Coral Gables — Full Bathroom Suite
Bathroom remodels in Miami typically range from $18,000 for a guest bath refresh to $80,000+ for a master bath with marble shower walls, custom vanity, and freestanding tub. Most mid-range Miami bathroom renovations land between $28,000 and $55,000. Condo bathrooms cost slightly more due to waterproofing requirements and HOA-mandated insurance coverage.
A standard Miami bathroom remodel takes 4 to 7 weeks from demolition to final walkthrough. Brickell, Sunny Isles, and Aventura condo projects often add 1 to 2 weeks for HOA approvals and freight elevator scheduling. We provide a written timeline at contract signing.
Yes. Any Miami-Dade bathroom remodel that changes plumbing, electrical, or relocates fixtures requires a permit from Miami-Dade County or the local municipality. Condos require an additional architectural review from the HOA. AP Stone handles permitting and HOA paperwork as part of every bathroom project.
Porcelain and natural stone (marble, travertine) perform best in Miami showers when paired with a proper waterproofing membrane. Avoid unsealed ceramic in shower applications — it absorbs moisture. We install a Schluter-Kerdi or equivalent membrane on every Miami shower we build, regardless of tile choice.
