I have tried to figure the reason it was installed the way it was (door opens into the hall with the knob closest to the bedroom door). This requires you to either open the bedroom door, step in and open the door, step back into the hall, close the bedroom door, step into the bathroom and then close the door behind you, or stand on the stairs, swing the door all the way open, walk up the stairs and into the bathroom, and shut the door! Today I flipped the door and put the hinges on the bedroom door side of the bathroom door frame. Now, if there is someone sleeping with the door to the bedroom door closed, you walk up the stairs, open the door into the bathroom by swinging it into the hall, step in and close the door. Much simpler, much easier, and in my book, much easier.
