Tile is beautiful. What's behind it is what lasts. We build every shower on the complete Schluter system, the same membrane, substrate, drain, and uncoupling products trusted by luxury builders for more than fifty years. No compromises on waterproofing. No weak links behind the wall.
Grout is porous. Caulk joints fail. In an old school mud bed shower, water reaches the substrate within a year and starts rotting studs, subfloor, and drywall, often for a decade before a single drop shows up on the ceiling below.
Florida slabs expand and contract with humidity. Plywood subfloors flex. Tile is rigid. Without something between them to absorb that movement, stress cracks the grout and eventually the tile itself.
Cement board absorbs water. Drywall behind it absorbs more. By the time you notice the musty smell, the wall cavity is already compromised, and the only fix is a full tear out.
Each piece is designed to bond to the next. There’s no mixing and matching with other brands' waterproofing, because the whole point is an unbroken seal from the wall studs to the drain.
A pliable, bonded waterproofing membrane and vapor retarder. Goes directly over the substrate before tile, the shower walls and pan are sealed against water penetration before a single square foot of tile is laid.

Lightweight, 100% waterproof construction panels that replace traditional cement backer board. Serve as the structural substrate and part of the waterproofing envelope in one product, dramatically cutting shower build time.

Drains engineered to bond directly to the KERDI waterproofing layer, no surface mounted retrofit seals that can fail. The linear KERDI LINE drain enables curbless, zero entry showers with a modern low profile grate in 40+ patterns.

A polyethylene membrane installed between the subfloor and tile. It neutralizes the stress differentials between substrate and tile caused by seasonal movement, subfloor flex, and thermal expansion, the #1 cause of tile cracks in poorly built floors.

Combines DITRA’s uncoupling with integrated heating cables under the tile. Programmable comfort on cold mornings, zero cracking, no increase in floor height. Popular on master bath remodels in Tampa Bay.
Read the product spec ↗Every component, walls, curb, niche, bench, drain, bonds to the same KERDI membrane. There’s no seam, no caulk joint, no drywall paper waiting to fail. Leak ready from day one.
Your subfloor flexes with the seasons. Your slab expands in summer heat. Without an uncoupling layer, that movement transfers straight into grout lines and cracks your tile. DITRA eats the movement before it reaches the stone.
Schluter pioneered the modern tiled shower in Europe in 1966 and has been the trade standard for high end residential bath work in North America for decades. Every Coastal Tile shower is built on the same system.
