Schluter Kerdi Prefabricated Sloped Shower Tray

Schluter-KERDI-SHOWER-LT/-LTS are prefabricated expanded polystyrene sloped trays with integrated KERDI waterproofing specifically designed to accept the KERDI-LINE linear drain. The trays are available in 39" x 39" (100 cm x 100 cm), 55" x 55" (140 cm x 140 cm), 48” x 48” (122 cm x 122 cm), 36” x 72” (91 cm x 183 cm), 38” x 76” (97 cm x 193 cm) and 36” x 55” (91 cm x 140 cm) sizes. The KERDI-SHOWER-LT/-LTS are available with center (-LT) and perimeter (-LTS) drain placements in ten configurations with reduced perimeter heights to aide in the installation of curbless showers.

How to Install Your Kerdi Shower Tray

1. Any leveling of the floor must be done prior to the installation of the shower tray. If necessary, cut the tray to size prior to application. The shower base can also be extended beyond the tray using dry-pack mortar, which is in turn covered with the KERDI membrane.

2. Cut the flat end of the KERDI-SHOWER-LT/-LTS tray to fit around the channel support. Apply Schluter SET, Schluter ALL-SET, Schluter FAST-SET, or unmodified thin-set mortar to the substrate using a 1/4" x 3/8" (6 mm x 10 mm) square- or U-notched trowel. Slide the KERDI-SHOWER-LT/-LTS under the edge of the channel body flush with the surface of the channel support, making certain to solidly embed the tray in the mortar. Check the underside of the tray to ensure that full coverage is achieved.

Note: When KERDI-LINE is placed at an intermediate location (e.g., center of shower), it is recommended that the KERDI SHOWER-LT tray be cut by equal amounts from the ends to ensure a consistent height of the first course of tile. When KERDI-LINE is placed adjacent to a wall, cut the KERDI-SHOWER-LTS tray from the thicker end to ensure a flush transition at the drain.

At Schlüter-Systems, we pride ourselves on being pioneers in the tile assembly industry.

What are the KERDI-SHOWER and KERDI-BOARD prefabricated substrates made of? Can they really support the tile assembly?

The KERDI-SHOWER and KERDI-BOARD substrates are lightweight, stable bases made from high-strength EPS foam and integrate with the Schluter-Shower System. They support typical shower loads like glass doors or walls after tiling and grouting.
What is the largest size hole I can cut in the subfloor for the drain?

The maximum would have a 5” diameter. A template is included in the drain kit box to guide the application.

Very convenient to use. Easy to cut, no dust, no mess. Yes, it's strong enough to walk on (just don't wear cleated shoes or high heels). Crazy expensive. Consider less-expensive alternatives from other brands. They're likely just as good.

Decent deal for what it is. Frankly I don't trust Schluter Kerdi stuff that much as have heard bad stories, and my contractor had lot of pain and trouble with applying Kerdi-Band well and having it pass leak tests, but this was significantly cheaper than similar tray from Laticrete and other competitors. After not so great luck with Kerdi-Band for sealing seams and corners we just decided to coat all the seams, corners, and fastener holes and possibly non-waterproof-areas with liquid membrane and that seemed to work better. So don't feel forced to have to use other Kerdi stuff with a Kerdi pan. Just coat it with liquid membrane (and esp all seams, corners, maybe with the corner mesh etc) if want to go with liquid membrane. Using some polyurethane sealant in corners and seams (leave 1/8” gap to allow for it when installing waterproof foam wall board) before the liquid membrane doesn't hurt either (we used GoBoard sealant).
