Schluter KERDI Kereck-F Preformed Inside Corner 10 Pack

The Schluter KERDI Kereck-F preformed inside corner seals the hardest spot in a KERDI waterproofing assembly — the concave corner where two shower walls meet. Rather than folding sheet membrane by hand and hoping it stays sealed, you set a molded corner that fits the 90-degree angle every time. It is built for tiled showers, tubs, and other wet areas handled by pros and confident DIYers.

Each Kereck-F is molded from KERDI membrane, so it bonds with thinset and ties directly into your KERDI walls and KERDI-BAND seams. This is the inside corner for wall-to-wall junctions, and this box holds 10 pieces for a full bathroom or a multi-shower job. Press it into thinset over the membrane and roll out the trapped air.

Pros who build KERDI showers keep these corners on hand. Tile Outlets stocks the Kereck-F corners and the rest of the KERDI system.
