I have a 2-piece fiberglass tub & surround. The unit came framed together and is joined behind the unit at a lip that surrounds the tub.
1) Is it at all possible to install the unit together joining them at the lip that runs behind the unit? Or should I not worry and just secure them by the exposed perimeter lip that the drywall will go over.
2) What is the best way to cut holes in the fiberglass for the faucet and controlls.
3) Should I use sealant between the tub & surround?
