Schluter Kerdi Prefab Sloped Shower Tray — Waterproof, Ready to Tile (36x48, Center Outlet)

Introducing the Schluter Kerdi Prefab Sloped Shower Tray, a purpose-built shower base designed to simplify tile installations while delivering a dependable, water-smart substrate. Engineered for modern bathrooms, this tray combines a streamlined form with trusted waterproofing to help you achieve a clean, tile-ready shower space without the typical mud-bed steps.

Built-in waterproofing for peace of mind

The tray integrates Schluter-KERDI waterproofing, creating a continuous moisture barrier beneath the tile. This built-in shield helps minimize the risk of water intrusion in the shower envelope, enabling a watertight surface that pairs with compatible Kerdi membranes and drains. By consolidating layers, you may experience fewer on-site waterproofing steps and a simplified installation path.

Ready to tile — speed and reliability

Designed for immediate tile application, the tray provides a solid, dependable foundation out of the box. With a robust base and an even, true plane, you can move from substrate to tile more quickly, helping projects stay on schedule. The ready-to-tile nature supports consistent tile layout and reduces the need for extensive prep work.

Flexible design options to fit your project

Schluter offers twelve sizes to accommodate replacement and new-construction scenarios. The product line includes neo-angle and off-center drain variants, offering layout flexibility for various shower footprints. The center outlet position on the 36" x 48" model delivers a practical option for common bathroom configurations.

Lightweight and durable for lasting use

Constructed from lightweight expanded polystyrene, this tray is easy to install and handles well during setup. The material is designed to hold up under daily shower use, providing a stable substrate that tiles can faithfully adhere to over time.

Long-term coverage with a professional warranty

When installed according to the Schluter Installation Handbook and Technical Data Sheet, the tray is backed by a 10-year limited warranty against manufacturing defects. Adhering to guidelines and industry standards can help maintain performance over the years.

Practical notes for real-world use

In practice, installers often appreciate the combination of a streamlined base and integrated waterproofing, which can lead to a neater shower interior and fewer surprises after tile work begins. The center-outlet option adds layout versatility for different drain plans, while the product’s lightweight nature can improve handling during installation.
