Shower and bathtub liners allow homeowners to avoid a complete remodel.

Bathtub and shower liners and acrylic wall systems allow homeowners to refinish bathrooms quickly and avoid the hassle of removing the old tub or shower. Several companies across the country offer and install the replacement units. The liners can be custom-fitted and provide a watertight seal without a complete bathroom remodel.

The shower systems offer seamless walls with no corner joints and slip-resistant floors. Bath Fitter® can also convert bathtubs into extra-large showers by removing the old tub and installing a one-piece shower surround in its place.
