I would like to change the direction of the toilet so it would have its back to the door rather that the front of the bowl. Is this possible without having to change all the plumbing? Right now our door swings into the hall as it would not clear the toilet if it was to swing inside.

All you wish to do is turn the toilet, not move it. Is that correct?You can do this without going into the floor if you can turn the flange. What material are the pipes and flange? Let me know. Tom
