Pride Plumbing came out and provided a cost estimate to perform the following work: 1) remove and replace a walk-in shower's drain and P-trap; 2) cut an access in the wall behind the shower, repair a water leak using new PEX piping and fittings, and install a plastic plumbing access panel over the hole we cut in the wall; and 3) replace a leaking two handle bathtub/shower valve with a new Gerber two handle model (this would include cutting an access in the shower wall, replacing the valve along with short sections of its hot and cold water supply lines with new PEX piping and fittings, and adding new stems, washers, seats, handles, and escutcheons).
