How to Install a Shower Pan Liner on Concrete

Installing a shower pan liner on a concrete base is an essential step in creating a waterproof and durable shower. A shower pan liner acts as a barrier between the concrete and the shower floor, preventing water damage and mold growth. This guide will walk you through the process of installing a shower pan liner on a concrete base.

Materials You'll Need:

  • Shower pan liner: Choose a durable liner made of PVC, CPE, or another waterproof material.
  • Utility knife: For cutting the liner to size.
  • Measuring tape: For accurately measuring the shower pan dimensions.
  • Level: To ensure a level installation.
  • Concrete adhesive: For securing the liner to the concrete base.
  • Safety glasses: For eye protection.
  • Work gloves: For protection during installation.
  • Trowel: For spreading concrete adhesive.
  • Drain: To drain water from the shower pan.
  • Silicone sealant: For sealing the drain and any gaps between the liner and walls.

Installation Steps:

  1. Prepare the Concrete Base:

    • Clean: Thoroughly clean the concrete base, removing any debris, dirt, or loose materials.
    • Level: Ensure the base is level, using a level and adjusting the height of the concrete base as needed.
  2. Measure and Cut the Liner:

    • Measure: Accurately measure the length and width of the shower pan, adding extra allowance for the drain and any walls.
    • Cut: Using a utility knife, carefully cut the liner to the desired size, making sure the edges are straight and even.
  3. Apply Adhesive to the Concrete:

    • Apply: Apply a generous layer of concrete adhesive to the base of the shower pan.
    • Spread: Use a trowel to spread the adhesive evenly over the entire surface.
  4. Install the Shower Pan Liner:

    • Position: Carefully position the liner over the adhesive, ensuring the edges are flush with the walls.
    • Press Down: Press down firmly on the liner to ensure it is securely adhered to the adhesive.
  5. Install the Drain:

    • Position: Cut a hole in the liner for the drain, ensuring it is centered and level.
    • Install: Securely install the drain in the hole you cut.
  6. Seal the Drain and Gaps:

    • Seal: Use silicone sealant to seal the drain and any gaps between the liner and the walls.
    • Smooth: Smooth the sealant with your finger or a tool to create a smooth and waterproof seal.
  7. Let the Adhesive Dry:

    • Dry Time: Allow the concrete adhesive to dry completely according to the manufacturer's instructions.
  8. Install the Shower Floor:

    • Install: Once the adhesive is dry, install the shower floor, making sure it is level and securely attached to the liner.

Tips for a Successful Installation:

  • Inspect: Before starting, inspect the concrete base for any cracks or imperfections. Repair any damage before installing the liner.
  • Overlap: When installing the liner, make sure to overlap the seams by at least 4 inches.
  • Dry Fit: Before applying adhesive, dry-fit the liner to ensure it fits properly and is level.
  • Ventilation: Ensure adequate ventilation during installation and drying to prevent moisture buildup.
  • Professional Help: If you are unsure about any aspect of the installation process, consult a professional for assistance.

Installing a shower pan liner on a concrete base is a relatively straightforward process. By following these steps and taking necessary precautions, you can ensure a waterproof and durable shower that will last for years to come.
