Frequently Asked Questions
How do ready-to-tile shower benches work?
KERDI SB benches are dense waterproof foam shapes that bond to the wall and floor with thinset, get their seams banded into the shower's waterproofing, and then tile over — no framing or mud work.
Corner bench or full-width bench?
Triangular corner benches fit standard showers without crowding the standing area. Rectangular benches suit wider showers and accessibility needs — comfortable seating starts around 15 inches deep at 17–19 inches high.
Can a tiled bench hold an adult's weight?
Yes — installed per spec, foam benches are rated well beyond typical body weight (KERDI SB benches support over 400 lbs once tiled).
What's the advantage of an engineered stone bench top?
One solid piece means no grout joints on the seat — nothing to seal, nothing to stain, and a smooth, comfortable surface that sheds water.
