Product Description:

KERDI-SHOWER-CB is a height compensation board made of lightweight expanded polystyrene used to accommodate the drain body and waste pipe height, when installing the Schluter-KERDI-DRAIN-H in conjunction with Schluter-KERDI-SHOWER-T/TS/TT shower trays. The compensation board can easily be cut to size to fit around the drain and waste pipe, and multiple boards can be used to fit the size and shape of the shower.

The Schluter®-KERDI-SHOWER-CB Compensation Board (Model: KSCB906101220) is a prefabricated substrate panel designed to fill space around the perimeter of a shower tray, providing a level and stable base for tile installation. Specifically engineered for use with Schluter®-KERDI-SHOWER-T/-TS/-TT shower trays, this compensation board measures 90-5/8" x 6" x 1-1/2" and is made from high-density expanded polystyrene (EPS) for lightweight durability and easy handling.

Ideal for customizing shower base dimensions or bridging the gap between the shower tray and surrounding floor, the KERDI-SHOWER-CB ensures a smooth transition and even surface. It is fully compatible with Schluter® waterproofing systems and can be easily cut to size on-site. Designed for quick and secure installation using thin-set mortar, this compensation board supports tile or stone finishes and enhances the integrity of tiled shower floors.

Whether used in residential or commercial applications, the KERDI-SHOWER-CB helps create a seamless and watertight shower assembly in bathrooms, wet rooms, and curbless entry shower installations.
