Suggested Shower Bench Dimensions
We use 18" when setting our seats. When building your framing, keep in mind what materials (CBU, plywood, tiles/stone etc) will be added to the framing height. Build it with a slight slant away from both walls to allow the water to run off. Will you have a curb, shower doors, shower curtain, glass block? If you plan to have a curb and curtain, you may want to have the seat width less than 45" to allow the curtain to sit between the side of the seat and the curb.
