The OneLiner shower pan by Dix Systems is a pre-formed, seamless polyethylene plastic alternative to the PVC shower pan liner. It is superior to the PVC liner because it does not puncture or tear, and the drain can be placed anywhere. All of our OneLiner shower pans are subjected to waterproof testing during the manufacturing process, to ensure our shower pans are leak proof.
Also, it is not necessary to include any backing between the wall studs since the OneLiner includes structured walls that are 7 inches high. You can use the OneLiner independently with lath to reinforce the mortar or install the shower pan with the OneLiner Installation Kit by Dix Systems.
The OneLiner - Prefabricated shower pan liner is recommended for a simple and efficient installation
