If you're building a custom shower and want a foolproof, watertight foundation, this Schluter Kerdi prefabricated sloped tray is the gold standard.
It's 38 inches by 76 inches – a nice size for larger showers – and comes with integrated KERDI waterproofing built right into the surface.


The tray is made from expanded polystyrene – lightweight but surprisingly strong – and it's pre-sloped so water drains perfectly toward the side outlet location.

Installation is straightforward if you've done tile work before.


Schluter has been innovating in tile systems since 1966, so you know this is built right.
Whether you're a pro contractor or a confident DIYer, this tray takes a ton of guesswork and risk out of building a waterproof shower.
Reliable, tested, and trusted by tile pros worldwide.
