Schlüter-KERDI-SHOWER-LTS is a sloped tray made of compression-resistant polystyrene with pre-adhered Schlüter-KERDI waterproofing. In showers, it creates a sufficient slope to the linear drainage Schlüter-KERDI-LINE positioned along walls. The sloped tray is installed on a level, flat, load bearing substrate and fitted to the drainage channel. In cases of vertical drainage, the sloped tray can also be installed directly on suitable substrates. Where necessary the trays can be cut to size with a utility knife, using the pre-marked cutting grooves on the underside of the tray.
