Protect the subflooring beneath showers from costly and harmful water damage with water tite PVC shower pan liner. This gray PVC membrane features lines every 6 in to facilitate accurate measuring and cutting and may be glued directly to the drain for a positive seal with no underlay-mount required. A 40 mil thickness makes this liner ideal for use in tile showers as well as other concealed waterproofing applications. Choose from rolls with 48, 60 and 72 in widths. Dam Corners are also available for convenient and complete waterproofing coverage.
