The 60" × 6" × 4-1/2" KERDI-BOARD-SC shower curb — the entry threshold of your shower, built the right way. Pre-made from KERDI-BOARD, it's waterproof, ready for tile, and eliminates the headache of building a custom mortar curb from scratch.

Position it at the shower opening, seal the joints with KERDI-BAND and KERDI membrane, and tile directly. The curb integrates cleanly with KERDI-SHOWER-T and TT shower trays, or with a mortar base system.

Pro Tip: A 60" curb works for wide shower openings and double-door designs. If your opening is smaller, Schluter also makes 38" and 48" versions — make sure you're ordering the right length for your rough opening. The 6" height is standard and allows for a single tile course on the curb face with minimal cutting. Waterproof the curb faces on all three sides (inside, outside, top) before tiling — it's often the part that gets rushed and the first place a leak develops.
