The OneLiner, by Dix Systems, is seamless, has no folds, and is thoroughly tested during manufacturing to ensure it is 100% waterproof against any type of leaks. Our shower pan liners are *prefabricated with 7 inch structured walls (may vary within one eighth of an inch), which removes the necessity of including any type of backing between the shower wall studs. The OneLiner prefabricated shower pan liner can be installed with lath for mortar reinforcement or for ease of installation, install it with our all-in-one OneLiner installation kit.

The durability and exceptional design of our polyethylene plastic OneLiner shower pan liners means no tears, no punctures, and no leaks. In fact, the OneLiner can tolerate even the worst conditions during your shower renovation or construction.

To eradicate the risk of mold and mildew from “standing water” and in the event that water does find its way through your mortar bed grout joints, you can ensure the water will still be properly drained if you do the following:

    1. Install a pre-pitch beneath the shower pan liner (see our Quick Pitch pre-slope product)
    2. Install a think mortar bed (over the shower pan liner) prior to tile installation

Also, to ensure that your shower curb also remains leak proof, we recommend you wrap your curb framing with Bituthene Curb Seal.

*Another unique thing about the OneLiner shower pan liner by Dix Systems is that the translucent polyethylene plastic allows you to see where the drain is located. This is a great advantage over other pre-formed shower pan liners that are pre-manufactured with only one permanent drain position. With the OneLiner, you can use your existing drain location no mater where it is situated on the shower floor.

*The OneLiner gives you the flexibility of choosing both the shower drain location and the shower curb location during construction!

Dix Systems also carries RedGard waterproof roll on membranes for showers.

*Drain location and curb are created onsite which give you the versatility to place them wherever you choose.
