ABSTRACT:
The invention relates to a flexible, waterproof shower pan liner comprised of a water-insoluble thermoplastic sheet. The shower pan liner includes on at least one surface selected indicia such as product information or plumbing codes at regular intervals. The indicia are embossed into the shower pan liner thereby eliminating the need for a protective top coat. In a process for making the invention, the thermoplastic is heated, calendered, and thereafter embossed with the selected indicia while in a heated condition.
