## Description

The Schluter KSLT915/1830S is a prefabricated sloped shower tray designed for ease and reliability. It is waterproof, ready to tile and features integrated KERDI waterproofing. It reduces weight and installation time. Made of lightweight, expanded polystyrene. Floor can be sloped on a single plane to KERDI-LINE, which enables the use of large-format tiles and creates interesting design opportunities. Designed for use with the KERDI-LINE linear drain (sold separately). Available in ten configurations with center drain and perimeter drain placements with reduced perimeter heights that simplifies construction of curbless showers. Founded over 40 years ago by a master tile setter, Schluter Systems pioneered innovative tile and bathroom waterproofing solutions, consistently setting industry benchmarks for craftsmanship and durability.

Review: Haven’t installed it yet. Love the concept. Reviews online are good. I can’t get over the fact however that I spent $400 on a piece of styrofoam. 🤷‍♂️
Review: Great way to make a shower base to size. When I installed it it did shift an eighth of an inch but my setting mix was a little wet.

## Questions & Answers

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

### ⭐⭐⭐⭐⭐ Review
*by J***S on 26 July 2024*

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.
