I have an original 70's fiberglass tub & shower surround. It has a cracked area near the faucet that showed obvious repair when I bought the house 8 years ago and is now much worse & probably leaks. The whole tub/floor feels weak, even to me & I weigh 100 lbs. So after all that - I am thinking of how to replace it, and think I want to do some sort of custom tiled shower & tub. If I were to rip out the existing surround (I am sure easier said than done), is there some sort of frame underneath? Do you essentially build a tub with plywood, then backerboard & tile? We have done several projects successfully and I would like to do most (or all) of the work ourselves.
Thanks.
Thanks.
