Product Description:

The Schluter Systems KERDI-SHOWER-CB Compensation Board KSCB906101220 is a premium prefabricated polystyrene substrate specifically engineered to accommodate height transitions when installing the Schluter KERDI-DRAIN-H flange assembly in combination with KERDI-SHOWER-T, KERDI-SHOWER-TS, or KERDI-SHOWER-TT pre-sloped shower trays. With its precise dimensions of 48" x 24" x 3-1/2", this high-density expanded polystyrene (EPS) board allows for reliable compensation of vertical elevation, making it an essential component for curbless showers, barrier-free bathroom designs, and ADA-compliant installations. Whether you're planning a complete bathroom renovation or a new tiled shower system, KSCB 90 610 1220 compensation board provides unmatched support and compatibility within the Schluter waterproofing system.
Designed to work seamlessly with Schluter's integrated waterproof shower system, the KERDI-SHOWER-CB is ideal for residential and commercial shower installation projects. It provides height correction beneath the KERDI shower tray and drain assembly, ensuring proper slope to the drain and eliminating the need for custom mortar bed construction. The board is lightweight yet structurally robust, allowing for quick cutting and easy handling on-site. It supports a wide variety of tile types, including ceramic, porcelain, granite, and marble, and is suitable for tiled shower bases in walk-in showers, linear drain systems, and custom bathroom remodeling applications.

This EPS height compensation board helps simplify the installation process while maintaining the full integrity of Schluter’s tile underlayment and vapor barrier systems. When combined with Schluter KERDI waterproofing membrane, KERDI-BAND sealing strips, and Schluter thin-set mortar (such as Schluter ALL-SET), installers can create a waterproof assembly that protects substrates against moisture intrusion, mold growth, and long-term water damage. Ideal for use in tiled wet areas, such as showers, spas, steam rooms, and laundry rooms, this Schluter Systems board brings professional-level performance and ease of use to every project.

For professional tile setters and DIY homeowners alike, this height compensating solution allows you to elevate the performance of your shower base system. The board is compatible with Schluter prefabricated shower trays and can be used as part of a complete tileable shower floor system. It can be secured directly to concrete subfloors or wood substrates using modified or unmodified thin-set mortar, ensuring secure placement and leveling around drain pipe configurations. Its rigidity prevents deflection while allowing maximum tile bond strength, making it an optimal alternative to traditional mortar beds.

The Schluter KERDI-SHOWER-CB board also facilitates installations involving ABS or PVC KERDI-DRAIN-H flanges, depending on your plumbing type. It is also compatible with radiant floor heating systems, offering insulation and improved thermal efficiency. This installation accessory is frequently used in conjunction with waterproof shower curbs, drain grate assemblies, Schluter KERDI waterproof wall panels, and prefabricated corner seals. Whether you're outfitting a master bathroom, guest shower, or spa facility, this tileable substrate board is a trusted solution for waterproof and long-lasting results.
