Yes. The KERDI-SHOWER- T/-TS/-TT trays can be cut to size to fit various applications. Ideally, the tray should be cut by equal amounts on all four sides to ensure a consistent height of the first course of wall tile. However, slight differences can typically be made up with thin-set mortar when setting the floor tile. The shower base can also be extended past the perimeter of the shower tray using dry pack mortar. Waterproof the extended tray areas with Schluter®-KERDI.
