Installation of a linear shower drain
Measure and mark the position of the drain
The first step is to measure and mark the location where the drain will be installed with a tape measure. Linear shower drains are usually installed in four different ways: one-sided wall mounting, three-sided wall mounting, free floor mounting and floor mounting at the shower entrance.
Single-sided wall mounting is the most common type. In this case, the drain runs along one side of the back wall of the shower. The ends of the drain do not extend to the side walls of the shower.
Three-sided wall-mounted drains are the same as the single-sided wall-mounted drain, except that the ends of the drain extend to the side walls of the shower and rest against three sides instead of just one.
Free floor-mounted linear drains are located in the center of the shower and do not touch any of the walls.
Floor-mounted linear shower drains, as the name implies, run across the entrance of the shower between the two shower walls.
Depending on the option you choose, you may need to relocate the existing drain lines. Keep in mind that floor-mounted drains have less support than wall-mounted drains.
Calculate the height of the drain and cut a drain hole
One of the goals of installing a linear drain is to ensure that the top of the drain's grate cover is perfectly flush with the surrounding tile. To achieve this goal, you will need to calculate and measure the height of the drain so that the top of the drain is 0.15 cm below the adjacent tile before the grate is placed.
Attaching tar paper and wire laths
Cut the tar paper with a box cutter to cover the plywood subfloor. Make sure that the tar paper also covers the corners and the bottom of the shower walls. This tar paper layer will prevent the plywood floor from absorbing moisture from the shower pan mortar mix.
You can also use wire cutters to cut a piece of wire lath to place on top of the tar paper to add stability to the shower pan mortar mix.
Connecting and inserting the floor drain
Before you pour in the mortar mix for the shower pan, cut the wire lath and tar paper so that the floor drain can be inserted into the drilled hole and reconnected to the drain line. Make sure the drain is properly aligned and level according to the desired installation position.
Pour some water into the floor drain to make sure there are no leaks between the floor drain and the drain line. The fit should be tight enough that you don't need drain adhesive, but if you're concerned about the connection, apply drain adhesive to seal the parts together.
