Here's how you can build an intermediate shower pedestal

An intermediate shower pedestal is a structure used to elevate a shower tray or base above the floor level. It serves several purposes, including creating a more accessible shower area, facilitating drainage, and providing structural support for the shower enclosure. Here's how you can build an intermediate shower pedestal:

1. Materials and Tools:

  - Shower tray or base

  - Waterproofing membrane or liner

  - Construction adhesive

  - Concrete blocks or bricks

  - Mortar mix

  - Level

  - Tape measure

  - Trowel

  - Waterproof sealant

  - Grout

2. Prepare the Area:

  - Clear the area where the shower will be installed.

  - Ensure the floor is clean, level, and free from debris.

3. Install the Shower Tray:

  - Place the shower tray or base in the desired location.

  - Check that it is level using a spirit level.

  - Adjust the position as needed to ensure proper drainage towards the waste outlet.

4. Waterproofing:

  - Apply a waterproofing membrane or liner beneath the shower tray to prevent water damage to the floor.

5. Build the Pedestal:

  - Determine the height of the pedestal required to elevate the shower tray to the desired level.

  - Stack concrete blocks or bricks to form the pedestal beneath the shower tray.

  - Use construction adhesive to secure the blocks or bricks together and to the floor.

  - Ensure the pedestal is level and stable.

6. Mortar Bed:

  - Mix mortar according to the manufacturer's instructions.

  - Apply a layer of mortar on top of the pedestal.

  - Place the shower tray on the mortar bed and press it down firmly to ensure good adhesion.

  - Check again for level and adjust if necessary.

7. Sealing and Finishing:

  - Seal the joints between the shower tray and the pedestal using waterproof sealant.

  - Apply grout around the edges of the shower tray to fill any gaps and create a neat finish.

  - Allow the sealant and grout to cure according to the manufacturer's instructions.

8. Test the Installation:

  - Run water into the shower tray to test the drainage and ensure there are no leaks.

  - Check for any movement or instability in the pedestal and make adjustments if necessary.

9. Complete the Shower Enclosure:

  - Install the shower walls or enclosure according to the manufacturer's instructions.

  - Seal any gaps between the walls and the shower tray to prevent water ingress.

10. Final Checks:

   - Double-check the level of the shower tray and pedestal.

   - Inspect the entire installation for any signs of water leakage or instability.

By following these steps, you can build an intermediate shower pedestal to elevate your shower tray and create a more functional and aesthetically pleasing shower area. Always ensure to adhere to local building codes and regulations when undertaking any construction project.
