DreamLine™ universal shower wall panels are both a functional and beautiful addition to any shower. These versatile shower wall panels are made of Acrylic/ABS advanced materials, are designed for quick install and engineered to trim-to-size for most DreamLine enclosures. Ceramic tile walls for shower enclosures may look good, but are very difficult and expensive to install and even tougher to take care of. DreamLine™ shower wall panels install in hours and are easy to maintain and enjoy for years to come. Acrylic back walls for enclosures with 29 7/8” to 40 ˝” sidewall dimensions. Fits most DreamLine corner trays.
