Walk-In Shower Installation in South Florida

Walk-in shower installs in South Florida must follow the Florida Building Code, which sets rules for wet area sealing, tile substrate, and plumbing rough-in. Miami-Dade and Broward County fall inside the High Velocity Hurricane Zone (HVHZ). That zone adds extra rules for moisture control in any remodel touching exterior walls. Haven pulls more than 1,500 building permits per year across Miami-Dade, Broward, Palm Beach, Martin, and St. Lucie counties — every job by the book.

Our Bathroom Remodeling team handles every phase in-house. No subcontractors touch your job. This matters because bathroom tile work is all about sequence. The liner goes down before the mortar bed. The membrane laps the wall before the backer board. One skipped step means a leak — and South Florida's humidity finds every gap fast.

Haven completes more than 1,200 roofing and bathroom remodeling projects per year. Our warranty callback rate stays under 3%. That number reflects craft, not luck. It reflects crews who have tiled hundreds of shower floors and know how to read a slope.

A curbless walk-in shower has no step at the entry. Water stays in the shower by slope alone. The entire floor must pitch toward the drain at 1/4" per foot. This sounds simple. It is not. A standard shower pan has a built-in slope to a center drain. A curbless floor must be built up with a mortar bed shaped by hand to hit that pitch across the full area.

The liner or membrane must run under the entire mortar bed and lap up the walls at least 3 inches. This protects the subfloor and wall frame. In South Florida, where slab-on-grade construction is the norm, the plumber must core the slab to set the drain at the right depth. That depth depends on the tile thickness, mortar bed depth, and membrane layer. Get it wrong and your floor either pools or drains wrong.

Curbless showers also pair well with Accessibility Upgrades. A zero-threshold entry meets ADA Standards for roll-in shower access. If you or a family member uses a mobility aid, curbless design removes the biggest trip hazard in the bathroom. Haven builds these to code whether they are an ADA project or just a modern style choice.

Porcelain is the top choice for South Florida walk-in showers. It is dense, holds up to humidity, and comes in large formats that reduce grout lines. Large-format porcelain planks (12x48 or 24x48) give a seamless stone look without the upkeep of real marble. Grout lines collect mold in high-humidity climates. Fewer lines mean less scrubbing.

Natural stone like travertine and marble is popular in Coral Gables and Coconut Grove. It looks beautiful. It also needs sealing every year in a wet area. If you skip that step, the stone absorbs moisture and stains. Porcelain that mimics stone is a smart middle ground. You get the look without the upkeep.

For floor tiles in a curbless shower, smaller mosaic tiles (2x2 or penny tile) give more grout lines and better grip. Slip resistance matters. Florida code requires floor tiles in wet areas to meet DCOF (dynamic coefficient of friction) minimums. We spec only tiles that pass. Mixing a large-format wall tile with a mosaic floor tile is a common and practical design choice.
