Be aware that there may be code restrictions that impact your desired
finished payout. We had a home with a do-it-yourself bathroom where it was
almost impossible to sit on the toilet without having the shower door open.
Planned by an idiot. Rotating the toilet at install time or repositioning
the shower would have been easily accomodated by the footprint of the room
and plumbing. I'm sure it was illegal as anything, too.

Good luck!
