How to Install a Shower Tray

The shower tray, otherwise known as the base of your shower enclosure, is a very crucial fixture to install. After all, without it, you’ll have nowhere to stand for your showers! It is relatively easy to complete the install yourself without the assistance of a plumber, although you will need a basic knowledge of carpentry and plumbing to do so accurately. If you’re prepared to give it a try, follow our instructions below.

  • 1. Typically shower trays are fitted to wooden flooring, enabling you to access beneath. In the event that you cannot do this, a special kit is required in order to enable you to fit the waste kit beneath to ensure that you do not accidentally drill into any piping or cables.


  • 2. Position the tray to your liking and draw around the entirety of it in pencil. Ensure that you also mark the area where the waste will be deposited.


  • 3. Place the waste trap on the marked area, placing the outlet in the correct placement to the waste pipe running beneath your floor. You will then need to place two hole saws in place of your waste trap and drill through the centre of both using an electric drill. Insert your waste trap. In the event that the hole is too tight around the waste trap, you can open up some more space using a jigsaw. You’ll need to ensure that no pipes or cables lie directly beneath the space where you intend to drill.


  • 4. Cover the area with waterproof sealer.


  • 5. Ensure that the sealer is dry and apply a thick layer of mortar. You can level this off using a trowel until the surface is smooth and level.


  • 6. Attach a pair of glass suction lifters to the tray. These can easily be attached and secured in place, enabling you to lift the tray and apply it to the cement. Prior to doing this, you will need to remove the masking from the edges of the tray, if you haven’t already done so. You can then steadily lower your tray down onto the cement. You’ll want to press down to ensure that the tray is adequately stuck and remove the glass suction lifters.


  • 7. A spirit level can be used to ensure that the tray is adequately leveled out. In the event that the tray is not perfectly level to your satisfaction, at this point you can simply push whichever part of the tray is not ideally placed down with your hand.


  • 8. Use a small trowel to slice away excess mortar that has seeped out from beneath the edges of the tray.


  • 9. The tray requires a minimum of 24 hours to set in place. A silicone sealant or shower tray seal should be applied between the gap that connects tray and the wall to secure it in place.


  • 10. Once the silicone has dried, you will be able to tile the surrounding area to finalise the look of the space.
