I wanted to remodel the existing 20 year old fiberglass shower cubicle as it was trapping a lot of mold/grime. I knew that if I get a remodeler to do this, it would cost me 8-10k. So decided to source a part myself and just pay the contractor for the labor.
Took 2 labors total 14 hrs, spread over 3 days.
It involved tearing down the existing shower cubicle/door, installing foam backer boards, replacing the mixing valve, adding the new shower pan/walls/door and new shower trim.
