How difficult and costly would it be to move a bathroom about 3 feet? All new plumbing was just put in but there's a hall right behind the bathroom that is just a waste of space and a small bedroom on the other side of the bath that could have been made bigger. Would it just be a matter of adding some elbows and pipes or is there a lot more to it? I don't know anything about plumbing. Just a shame that so much space was wasted with the house being so small anyway. The bedroom is only just over 7 feet wide and could be around 10 which would make a big difference. It only has the one bedroom and it hardly fits a bed and dresser.
