How to fit a shower cubicle


Was this guide useful?

Difficulty rating: Medium

This is a reasonably straightforward job, and should only take a day (plus drying time for the mortar). Some fairly complex plumbing and electrical work is required if you are installing an entire shower system (new or replacement) - we would recommend you get qualified professionals to help.

Before you get started on any of our 'how to' guides, please take a moment to read through our DIY safety tips.

Top tips:
  • Ensure you have help for this task.
  • Make sure all drilling is done before using any silicone.
  • If you’re drilling though tiles put some masking tape over the spot you are about to drill to prevent the tile from cracking.
  • Make sure the wall plugs are inserted just past the tile’s surface to prevent the tile from cracking when the screw goes in.
  • Check there aren't any pipes or cables before drilling into walls or floors.

Step-by-step installation guide

Please note:

All installations will be different. These instructions should only be used as a general guide. Please always refer to the manufacturer’s instructions. If you are in any doubt whatsoever about how to carry out any of the steps, please seek professional advice.

1. Prepare the cubicle
  • Assemble the cubicle according to the manufacturer’s instructions.
  • With help, lift the assembled cubicle into position on the tray. This is generally a two man job.

2. Measure up
  • With your spirit level, ensure that the cubicle wall rails are perfectly vertical and that the bottom rail of the enclosure is properly positioned.
  • Now mark the wall through the pre-drilled fixing points on the wall rails (Figure 1).
Remove the shower tray. Cut a hole to make space for the trap and waste outlet pipe.

3. Fix and seal the cubicle
  • With help, lift the cubicle out of position and support it to stop it falling.
  • Drill holes for the screws using a 6mm masonry bit, then insert the wall plugs (Figure 2).
  • Squeeze a vertical line of sealant behind the wall rails, to create a seal between them and the wall.
  • With help, put the cubicle back into its final position and screw it to the wall.
  • Seal the outside of the cubicle where it meets the walls and tray/floor with a silicone sealant. Do not seal the inside (Figure 3).
Screw the panels into place with the fixings supplied with your surround.
