I am doing a bath remodel and have only a minor move to make. My bathtub is going back into the same location, however, it is 4 inches wider than the old one. I need to move the drain and supply lines over 2 inches to keep it on center and to line up the drain holes. The supply lines can be easily moved, I am just not sure how to go about the drain as it is fairly rigid - plastic. This is a second story bath.
