Brenda, yes this is a zero clearance curbless shower. The drain is a linear drain that is placed along the back wall. In this application the pebble flooring also goes on top of the drain, making it practically invisible. Where ever the drain is placed, the floor is sloped in that direction, so by placing it in the back of the shower the floor is sloped toward the back. There is no water leakage into the room. Hope that answers your questions.

Thank you very much.
