How to Install Shower Liners: A Step-by-Step Guide

Here’s a comprehensive guide on installing shower liners to ensure a watertight and durable shower enclosure. Whether you’re renovating your bathroom or building a new one, proper installation is crucial for maintaining a leak-free and functional shower space.

1. Prepare Your Workspace

Before you begin, gather the necessary tools and materials:

  • Shower liner: Choose from options like acrylic, PVC, or other waterproof materials.
  • Shower tray: Ensure it’s level and properly supported.
  • Wet Wall Gib Board: Use 10mm thickness for lining the walls.
  • Plumbing fittings: Install these before placing the shower tray.
  • Leveling compounds (for concrete floors) or additional nogs (for timber floors).

2. Level the Floor and Walls

  • Ensure the floor and walls are level and plumb.
  • For every 1mm the floor is out of level, adjust the enclosure by 2mm.
  • Avoid packing the tray; it must be fully supported.

3. Install the Shower Tray

  1. Wall Lining:

    • Use 10mm Wet Wall Gib Board to line the walls.
    • Double nail it to the studs/nogs at 200mm centers.
    • Do not Gib stop, seal, sand, or paint the Gib Board surface.
    • Backfill the hole cutout in the floor for the waste to fully support the tray.
    • For concrete floors, use concrete or a similar solid fill material.
    • For timber floors, add additional nogs or use leveling compounds.

  2. Position the Tray:

    • Mark the tray’s profile on the Gib board using a pencil.
    • Cut away the Gib Board 10mm above the pencil line.
    • Place the tray into the rebate and check its alignment.
    • The front face of the tray’s upstand should not protrude further than the Gib board surface.
    • If needed, rebate the tray further into the bottom plate.

  3. Check Level and Alignment:

    • Ensure the tray is level.
    • Align the waste outlet with the installed floor waste.
    • Peel away the protective masking from the tray’s sides and upstand.

4. Install the Shower Liner

  • Follow the manufacturer’s instructions for your chosen liner material.
  • Properly seal the liner to the tray and walls.
  • Ensure watertight connections around the waste outlet and any penetrations.

5. Complete the Enclosure

  • Install the shower fittings (plumbing fixtures).
  • Seal any gaps or joints with appropriate sealants.
  • Test the enclosure for leaks by running water.

6. Finishing Touches

  • Trim any excess liner material.
  • Install shower doors or screens according to the manufacturer’s instructions.

Remember, accurate installation is essential for the longevity and functionality of your shower liner. If you have any doubts, consult a professional or refer to specific product guidelines.

Happy showering! 🚿🛁
