I would like to remodel my bathroom and want to move the toilet and the shower but will leave the sink where it is located. So I will need to turn my toilet 90 degrees and move it to the right about 4 feet and also, what would be towards you if you walked into the bathroom, 3 feet. Then I want to put the shower where the toilet was. I will snap a picture and upload. What do I need to be concerned about. This is a one level home and has a basement.
