3-1/2" (8.9 cm) version: Accommodates the drain body and waste pipe height for KERDI-DRAIN-H installations

Boards can be easily cut to size and multiple boards can be used to fit the size and shape of the shower.

The 3-1/2" (8.9 cm)-thick compensation board is used to accommodate the drain body and waste pipe height, when installing the KERDI-DRAIN-H in conjunction with the KERDISHOWER-T/TS/TT shower trays.
