kiki, sure you can replace the whole showernd in my opinion you should. it’s not that big of a job, but yes hire a plumber. as far as price, it depends. sylvan was describing the best alternative, a custom stone or concrete and lead shower floor with beautiful tiled walls, should last many years. a lower cost alternative and what folks seem to expect in this pre-fab world is a fiberglass unit. there are some respectable ones, i prefer “sterling” brand myself. ask your neighbors, get a reference on a good plumber, and discuss your options with him, shouldn’t cost you nuthin’ for the bid. good luck kiki, and get them athletes a NEW shower!!!!!
