Schluter®-KERDI-BOARD-SB is a prefabricated shower bench, made of KERDI-BOARD, for use in conjunction with the Schluter®-Shower System. KERDI-SHOWER-SB is waterproof and ready for tile, leaving only sealing of joints and corners to complete waterproofing. The bench is available in triangular and rectangular configurations in the following sizes (width x depth x height). The triangular benches are 16" x 16” x 20” (41 x 41 x 51 cm) and 24” x 24” x 20” (61 x 61 x 51 cm). The rectangular benches are 38” x 11-½” x 20” (97 x 29 x 51 cm) and 48” x 16” x 20” (122 x 41 x 51 cm).

1. Apply Schluter-SET, Schluter-ALL-SET, Schluter-FAST-SET, or unmodified thin-set mortar to the floor and to the edge of the shower base and walls using a 1/4" x 3/8" (6 mm x 10 mm) square- or U-notched trowel.

2. Press the bench firmly into place and check the underside and backsides to ensure that full coverage and support are achieved. Verify that the slope on the surface of the bench is directed toward the shower base.

3. Install KREDI-BAND and KERDI-KERECK and KERDI-KERS-B (for triangular bench) to cover all seams and corners, ensuring a minimum 2” (50mm) overlap, and work the membrane into the mortar to achieve full coverage and remove air pockets.
