Miami — Miami-Dade
A true wet room is a continuous waterproofed space with no curb, a linear drain, and tile or marble that can handle full wet exposure. In Miami we build that system from the membrane up, flood-test it, then finish with large-format surfaces.
Wet room installation in Miami starts with a continuous ANSI A118.10 waterproofing membrane across the floor and wet walls, tied into a linear drain and sloped mud bed or foam tray. There is no traditional curb. Water is managed by pitch to the drain and a sealed membrane that wraps walls, niches, and thresholds. We flood-test the entire wet zone before large-format porcelain or marble tile is installed. Sheet systems such as Schluter Kerdi and liquid-applied ANSI membranes are both options depending on substrate and design.
South Florida humidity and condo living make open wet rooms demanding. Condensation and daily shower use stress every joint, so substrate prep, membrane detailing, and flood testing are non-negotiable. We install wet rooms in single-family homes and Miami-Dade condos, coordinating HOA access and documentation when required. Finish options range from rectified large-format porcelain to natural marble for master suites that prioritize design and longevity.

In Miami, a curbless wet room typically costs $8,000 to $18,000 for a standard master bath footprint including membrane, linear drain, and large-format tile. Marble finishes and complex niches push projects toward $15,000 to $25,000. Size, drain type, and material selection drive the final estimate.
A full wet room installation usually takes 6 to 10 working days: demolition and substrate, membrane and linear drain, flood test, large-format tile or marble, then grout and seal. Cure times for liquid membranes and thinset can extend the schedule. Occupied homes keep another bathroom available when possible.
Yes. Wet-area renovations that change drainage, waterproofing, or layout typically require Miami-Dade permits. We prepare documentation for inspections and provide flood-test records. Condo projects often need HOA approval in addition to the county permit.
