Pros and Cons of all-in-one bathroom or separate shower

Hate the ones where the toilet is in a tiny room by itself. When looking at rigs, try sitting down and see if your head hits the wall/door in front of the toilet when getting up. The DW is only 5' and has an issue with this in many we looked at. I'm 6'2" and for some I would have to leave the door open and sit at an angle to get knee room.

Also hate the ones where there are two doors plus a separate passage to the bedroom. It just wastes a lot of space.
