Building a mortar shower bed is a skilled trade — it takes experience to get the slope right, and a bad slope is a standing water problem that turns into a mold problem. The KERDI-SHOWER tray solves this by arriving pre-sloped, pre-formed, and ready to tile. No mortar bed, no slope math, no skilled mud work.

This 38" × 60" center-drain tray is lightweight expanded polystyrene — it's strong enough for tile but light enough to maneuver solo. Designed to integrate directly with KERDI-DRAIN. Overlay with KERDI membrane, tile, and you're done.

Pro Tip: This size works for a standard tub-replacement shower — the 38" width fits comfortably where a bathtub was removed, and 60" gives full standing room. Make sure your drain rough-in hits the center of the tray before setting it; relocating a drain after the tray is placed is a major problem. If your drain position is offset, Schluter also makes a KERDI-SHOWER-TS with an off-center drain placement specifically for tub conversions.
