Dimensions....

Wondering if you folks might be able to help me out. Will be working on doodling a sketch so Coyote Jack can do some engineering work for us. Looking at bathroom sizes. We would like the master bathroom to have a 36"x60" shower in it along with a single bowl vanity. Other bathroom, small vanity, crapper and perhaps one of those angled corner showers. Looking for wall to wall dimensions...So what say you folks? :happy1:
