In our new house, the bathroom (1.78, x 1.78m) has a rather awkward layout. The bath is to the left of the door and the sink to the right (the trapper is at the back right). This prevents the door from opening inwards enough for the user to get in. Currently the door opens outwards which is fine and dandy, but if you're coming up the stairs and the bathroom door opens, you'll probably find yourself at the bottom of the stairs again rather quickly...
The obvious (to me) solution is to move the bath to the back of the room so it lies along the back wall and move the toilet to the front left and leave the sink where it is. Now I know nothing about plumbing so I'll get someone to do it, but how difficult would something like this be to do ? The piping at the moment runs around the side of the room and is boxed off, and the room has floorboards which I presume you could run pipes though as well. Is it possible from a plumbing point of view to have a toilet that doesn't sit on an outside wall ? Would it be a rather expensive job to do ? The bath is a normal size bath (matches the smallest width that b&q do), so getting a smaller bath doesn't seem to be an option.
Any ideas ?!
