Refinishing a bathtub is a cost-effective way to reinvent your bathroom, reviving a tired, old tub to match new paintwork. It's also far less disruptive than demolishing the existing tub space and installing a new one. Refinishing is also an effective way to remodel your bathroom without replacing a rare tub or freshen up a bathroom in an old house where period details like an antique tub are part of the appeal.
