Really, a reglazed bathtub by Ace Refinishers Inc. is far superior to any liner or insert. With a resurfaced or reglazed bathtub there are no air pockets that contribute to the growth of mold, as is sometimes the case with liners. The price is far less for reglazing. Also, in the unlikely event that damage occurs, the repair is simple and quick with a reglazed bathtub.
