Actually, thats one part I am planning to shortcut. What I should do, is undo all three water lines to put drywall up with just a small hole. I need to look close at the one for toilet yet. But if it's not corroded, I'm going to oversize the holes and patch fill the drywall to avoid some plumbing. I did get a Fernco to cut down and piece in the drain for the sink so I don't need a huge cut in back of vanity.
