KERDI membrane
Bonded waterproofing membrane applied behind wall and floor tile — the core of the system.
Schluter®-Systems
Waterproofing that protects your whole bathroom.
Every Kaja bathroom is built on the Schluter® system — a bonded waterproofing assembly behind the tile, not just on the surface.
Why it matters
Tile and grout are not waterproof. The system behind them must be.
In a traditional bathroom, moisture works through grout into the wall and floor over the years — the hidden cause of mold, mildew and failed showers. The Schluter® system bonds a waterproof membrane directly behind every tile and connects walls, floor, drain and seals into one sealed assembly, so water goes down the drain and nowhere else.
Protects against water damage, mold and mildew
Certified waterproof — evaluated by ICC-ES
One engineered system, no mixed materials
Uniform coverage — no brush-on guesswork
Built for decades of daily showers
Installed by Schluter-trained Kaja crews
KERDI-BOARD
Waterproof building panels for walls, curbs, benches and custom shower features.
DITRA uncoupling membrane
Protects tiled floors from cracking while adding waterproofing underfoot.
KERDI-LINE & KERDI-DRAIN
Integrated linear and point drains that connect directly to the membrane.
Shower trays, curbs & niches
Prefabricated, ready-to-tile components with reliable slopes and clean lines.
Seals & corners
Matched pipe seals, mixing-valve seals and pre-formed corners — no weak points.
How we build it, step by step.
We prepare the space, set the sloped tray and curb, apply the KERDI membrane over walls and floor with sealed seams and corners, connect the integrated drain, then flood-test before a single tile goes on. Only after the system is proven watertight do we tile and finish.
