Tools and Materials Needed

  • 48-inch black linear shower drain
  • Measuring tape
  • Level
  • Screwdriver
  • PVC glue
  • Waterproof membrane
  • Tile saw

Consideration for Slope

Proper slope is however required for good drainage to be achieved. The floor should be slanting towards the drain with a gradient of ¼ inch per foot. This makes sure that water drains freely into the drain pipe without accumulating in a pool.

Choosing the Proper Location for the Drain

Linear drains are best positioned along one side of the shower base, whether against a wall or at the shower entry. This placement makes it possible to have only one slope on the opposite side of wall, making work of tiling easier besides enhancing proper drainage.

Part 3: Installation Steps

Now that you are ready, let me proceed to the installation process. First of all, we will divide the procedure into five key steps to make it as simple and clear as possible. Here are the steps that should be followed to avoid any problems during the installation process:

Step 1: Prepare the Shower Floor

  • Measure and Mark: Then, using a measuring tape, demarcate the position where the required drain will be installed. Make sure that its installment is such that there is a uniform slant towards the drain.
  • Cut the Floor: If needed, it is time to cut the floor with a tile saw at the place where the drain will be placed. Make sure the cut is clean and straight.

Step 2: Install the Drain Body

  • Position the Drain: Lay down the linear drain on the area that has been marked. Always make sure that it is parallel to the ground using a level.
  • Secure the Drain: Use the screws along with the screwdriver to fix the drain to the floor. Ensure that it is well anchored.

Step 3: Connect the Plumbing

  • Fit the Pipe: Join the drain with the other plumbing pipes using PVC glue. Make sure the connection is tight and cannot leak.
  • Test for Leaks: Some recommend to pour water into the drain in order to reveal leaks. If any are found, use silicone sealant to seal them.

Step 4: Applying Waterproof Membrane

  • Cut the Membrane: Measure the floor of the shower and cut the waterproof membrane to cover the surface of the shower floor and slightly above the walls.
  • Adhere the Membrane: Spread the membrane on the floor and ensure that the surface is free from bubbles. Use silicone to cover the edges to ensure that no water gets in contact with the circuit.

Step 5: Tiling the Shower Floor

  • Apply Mortar: Apply the mortar on the floor using a trowel. Make sure the surface is even in order to accommodate for the tiles.
  • Lay the Tiles: Lay the tiles on the mortar starting from the drain area and moving outwards. Make sure they are parallel and on the same plane.
  • Grout the Tiles: After the application of the mortar, spread grout between the tiles. Clean off the extra grout with a wet sponge.
