I am putting in a new tub and have already bought the desired tub, but discovered that the drain is 2 inches further from the wall than the original tub (move to right in picture). As you can see in the picture I will have to cut out a section of the joist and add a joist support to make room for the new drain.
My question, however, is what to do with the water supply lines. Can those be diverted without an extensive plumbing alteration and still be under code? Do they have to run vertical until the split?
In reality you don't have to cut that joist at all, just off set the overflow on a 45 to bring it back to the same side the original one sits on. Of coure you will need to use a lift and turn or a tip-toe waste and overflow assembly for it to work.
