Thanks for your description. I'd like to see a photo of the room but I can't find any online.
This is NOT bedroom A, but another one (either C or E). Everything about A is the same other than the location of the door to the bathroom, and the space between the seat and the wall. Image the bathroom extending to where the mirror is. That's the space that you lose.
I can't see these images. I'm not a member apparently.
