Placing the shower controls at the front of the shower keeps users from getting wet or sprayed with water that is too hot or cold. We used the "single fist" approach in selecting all materials so that regardless of grip, anyone could independently operate the shower. The foam niche enabled the line to go through the seat itself without excessive additional plumbing costs. The use of higher end, darker tile on the seat and niche are good for visual acuity.
