What is a good shower stall width and length?

Question

I'm designing my tiled shower 36" wide + 4" for the dam for a total of 40 inches. I'm also making it 6 ft long with a bench seat in the back.

Are these dimensions a good size or am I over doing it?

Answer 1

That is what I would consider a larger than normal shower but not overly huge.  Make sure that bench has a membrane installed correctly, and is sloped etc etc.  that will be the most likely failure area.  Best source for this job would be "Setting Ceramic Tile " by Michael Byrne.

Answer 2

The size sounds about right it will allow you to bend down and retrieve the soap without hitting your head. The bench seat is handy for getting to your feet.
