The Schluter-KERDI-SHOWER-KIT is an all inclusive package containing each of the components required to create a maintenance-free, watertight shower assembly without a mortar bed.Schluter-KERDI-SHOWER-ST/-SC are prefabricated substrates, made of expanded polystyrene foam, for tiled shower bases in conjunction with Schluter-KERDI waterproofing membrane and Schluter-KERDI-DRAIN. Schluter-KERDI-SHOWER-ST is a prefabricated, sloped shower tray that is specifically designed to accept the Schluter-KERDI-DRAIN and Schluter-KERDI waterproofing membrane. The tray is available in 48" x 48" (122 cm x 122 cm), 32" x 60" (81 cm x 152 cm), and 72" x 72" (183 cm x 183 cm) sizes. Schluter-KERDI-SHOWER-SC is a prefabricated curb that can be used with Schluter-KERDI-SHOWER-ST. Curb dimensions are 48" x 6" x 4-1/2" (122 cm x 15 cm x 11.5 cm). The integrated Schluter-Shower System eliminates the potential for leakage, efflorescence, and mold growth in the system, is maintenance-free, and dramatically reduces total installation time to ensure success and make shower installation easier than ever. Schluter prefabricated shower substrates provide an alternative to shower bases constructed of mortar. The shower tray and curb are especially useful in large-scale, repetitive jobs, such as hotels, apartments, and condominiums for the significant time savings that can be realized.
