Schlüter®-KERDI-SHOWER sloped trays and levelling boards

Systematically waterproof, due to the combination of sloped trays with the bonded waterproofing system Schlüter®-KERDI and levelling boards.

To make the installation as reliable and quick as possible, the matching sloped tray of the system was developed with an integrated Schlüter®-KERDI waterproofing membrane and a height adjusted levelling board. The basic sizes 100 x 100 cm and 140 x 140 cm can easily be cut to size with a utility knife to match the exact dimensions of the required installation, using the imprinted gridlines of the material for higher precision. For ease of packaging, storage and transport the sloped trays consist of two pieces, which are simply folded together with the Schlüter®-KERDI membrane serving as a hinge. The sloped tray without Schlüter®-KERDI surface may also be used as a sloped insulation layer under a screed. The sections below describe the various installation variations in detail.

  • Sloped trays and matching levelling boards available as sets
  • Sloped trays also available separately
  • Dimensions 100 x 100 cm and 140 x 140 cm
  • Sloped trays are packaged in space saving folded format
  • Imprinted gridlines for precise cutting to smaller dimensions • Waterproof connection to the shower channel with the Schlüter®-KERDI collar provided in the set
  • Easy waterproofing in wall and edge transition areas with Schlüter®-KERDI-KEBA
  • Sloped tray with integrated Schlüter®-KERDI waterproofing membrane
  • Fleece fabric for bonding with the tile adhesive
  • Optimal load distribution, which means no restriction for the size of covering materials (Size can range from large format pavers to mosaics – anything is possible)
  • Bonded waterproofing system with Schlüter®-KERDI, Schlüter®-KERDI-BOARD, Schlüter®-DITRA 25
  • Sloped trays can be used under screed without Schlüter®-KERDI
  • Suitable for linear drainage installations with horizontal or vertical drain


Schlüter®-KERDI-SHOWER-L is a two part sloped tray with a 2% slope and a pre-adhered coating of Schlüter®-KERDI for the direct installation of tiles in floor level showers and for the connection of the folded parts of the sloped tray. It is attached to the previously installed linear drain Schlüter®-KERDI-LINE in the centre area, with a precise fit over the substructure supplied at the corresponding construction site.
