Because the OneLiner is a structured seamless *Pre-Formed shower pan liner there are no folds or seams.
Every OneLiner is water tested at our manufacturing plant, eliminating concerns about leaky shower pan installation.
The OneLiner's unique design made of durable polyethylene plastic can withstand the worst construction conditions making punctures and tears non-existent.
When installing, it is recommended that you do a thin pre-pitch on the sub floor underneath any liner, and have a thicker mortar bed in the liner for the tile to sit on. The pre-pitch will guarantee that any water coming through grout joints into the mortar bed and liner will still find it's way to the drain. This helps to eliminate any standing water which can cause mold and mildew issues in the shower. When installing against 3 stacked 2x4s for the curb, wrap with Bituthene Curb Seal to guarantee a leak proof curb.
*Unlike other Pre-Formed shower pan liners that have a fixed drain location, the OneLiner Shower Pan Liner is made with a unique translucent material that allows you to determine the location of the drain and/or use your existing drain and drain location.
