Understanding Shower Tray Types

Shower trays come in various materials such as acrylic, stone resin, and more. Understanding the characteristics of each type helps in making an informed decision based on your bathroom requirements.

  • Low Profile Trays: Low profile shower trays are crafted to sit as close to the floor as possible, offering a step-free shower entry. Ideal for those seeking a ground-level shower experience or contemplating the installation of a Wet Room Shower Tray.
  • Adjustable Height Shower Trays: Standing on adjustable legs, these trays provide flexibility in height adjustment, allowing easy access to underlying pipes for maintenance. Whether lowering or raising to your preferred level, these trays offer adaptability.

Gathering Materials And Tools

Before you start the installation process, gather the necessary materials:

  1. Shower tray
  2. Adjustable legs or riser kit
  3. Silicone sealant
  4. Screws and screwdriver
  5. Spirit level
  6. Drill
  7. Wrench
  8. Pencil
  9. Cement
  10. Building sand
  11. Mortar trowel

Understanding the purpose of each tool is essential for a smooth installation. The right tools contribute to precision and efficiency throughout the process.

Preparing The Bathroom

  • Clearing the Shower Area: Begin by removing any existing shower fittings and clearing the designated area. This ensures a clean slate for the new installation.
  • Checking Floor Levelness:Use a spirit level to assess the levelness of the floor. Any unevenness should be addressed before proceeding to guarantee a stable foundation.
  • Ensuring Proper Drainage: Verify that the drainage system is in good condition and properly aligned with the new shower tray. Address any issues to prevent future complications.

Installing An Adjustable Height Shower Tray, Step-By-Step

Here’s how you can fit an adjustable height shower.

1: Positioning And Leg Adjustment

  • The stability of the shower tray is paramount. Place the tray in the desired location, ensuring a proper fit without clearance issues.
  • Screw the legs into position and adjust the height to your preference.
  • Attach the waste outlet to verify proper alignment.

2: Adjusting Riser Legs And Drainage

  • Adjust riser legs to achieve a suitable fall for waste drainage (typically 50 mm fall per metre of pipework).
  • Level the tray by adjusting corner legs initially, ensuring the centre leg is also fitted.

3: Connecting Waste Pipe

  • Determine the optimal route from the waste trap to the waste pipe.
  • Connect the outlet pipe to the trap if it's already in place.

4: Tray Placement

  • Position the tray, having pre-fitted the waste's bottom part to the pipework.

5: Level It Up

  • Use a spirit level to confirm the tray is entirely level. Levelness is crucial for proper drainage and avoids water accumulation.

6: All’s Well?

  • Confirm all legs are engaged, and lock nuts are tightened, touching the flange.

7: Testing Drainage And Finishing Touches

  • Pour water down the shower drain to check for smooth drainage without drips or leaks.
  • Cover gaps around the tray with skirting boards or side panels.
  • Apply a bead of sealant behind the tray, between the wall and tray, for cushioning and a primary seal against leaks.
  • Fit tiles, leaving a 3mm gap between the tray and tiles. Apply sealant in this gap for a secondary seal.

9: Applying Sealant And Final Checks

  • Run a bead of sealant along the top edge and wall.
  • Cut side panels to length, fixing leg clamps before attaching the panel.

Installing A Low-Profile Shower Tray, Step-By-Step

1: Floor Stability

Position the shower tray and test the floor's strength. If necessary, reinforce the floor with marine plywood.

2: Access Hatch

Cut an access hatch in floorboards next to the tray for easy maintenance access.

3: Preparing For Pipework

Remove part of the floorboards to make room for pipework, as low-profile trays have limited space beneath.

4: Mortar Application

  • Mix building sand and cement to create mortar. Spread a thin layer over the tray area.
  • Position the tray, ensuring complete levelness. Allow drying for approximately 24 hours.

5: Connecting Waste Trap

  • Use the access hatch to connect the waste trap to the outlet pipe and the outlet pipe to the waste pipe underneath the tray.

6: Sealing

  • Use silicone sealant for a secure, watertight seal around the entire tray.

7. Cleaning Up

  • Clean the installation area by removing any excess sealant or debris

Maintenance Tips

To maintain your shower tray post-installation:

- Regularly clean to prevent soap scum or limescale buildup.

- Use white wine vinegar and baking soda for rust marks.

- Employ mold cleaning spray to prevent mildew in the tray sealant.
