The shower tray is an important part of your shower enclosure because it instructs water flow to the drainage point in your bathroom.

Shower trays serve the primary purpose of preventing water leaks. Water has a natural tendency to take the path of least resistance, and once that path has been chosen, it is extremely difficult to reverse.

The best shower tray in the world will not help you if you do not properly assemble it.

Since water flows in the direction of least resistance, it is difficult to redirect it once it has begun to flow in the wrong direction, far from the drainage site.

As a result, installing a shower tray correctly is critical because it ensures quick water drainage, avoids costly leaks, and keeps your bathroom dry.

Shower trays, particularly rectangular shower trays, are designed to redirect the flow of water.

When you shower, the tilt of the tray ensures that the water flows straight to the drain; it’s physics at work. It makes certain that water flows in the proper direction.

Types of Shower Trays

  • Acrylic Shower Tray: It’s also widely recognized as an ABS shower tray.  They are as inexpensive as ceramic and are also easy to install.
  • Ceramic Shower Tray: It’s inexpensive, long-lasting, and stain-resistant, just like a bathroom sink. In contrast, ceramic shower pans are heavy and cold to the touch. Manufacturers prefer stone resin over ceramic because it enables a faster manufacturing process.
  • Stone Resin Shower Tray: This tray is made from crushed stone and resin, which is placed into a mould and allowed to cure. Following that, a protective layer of gel is applied to the tray, and a non-slip design is incorporated into the design. Aside from the fact that some models are heavy, there are no disadvantages to using a stone resin shower tray.
  • Acrylic Capped Shower Tray: To achieve a superior finish, it manages to combine the toughness of a resin tray with the attractive appearance of an acrylic sheet.
  • Marble Shower Tray: It is without a doubt the most distinctive shower tray available. Any bathroom shower design will benefit from the use of classic marble. Marble shower trays, on the other hand, have the dual disadvantages of being both heavy and expensive.

How to Install a Shower Tray?


Put the shower tray where you want it and make sure there are no clearance issues.

Screw the legs into place and adjust the height of the tray until it is at the desired level. Attach the waste outlet to the tray to ensure that everything is in place.


Make sure the riser legs are adjusted to allow for an adequate fall for the waste to drain away, which is typically 50mm per metre of pipework length. Initially, adjusting the key corner legs first may make it easier to get the tray level. Remember to include the centre leg.


Determine the most direct path from the waste trap in the tray to the waste pipe.

Connect your existing outlet pipe to the trap if it is already in place. Place the tray on top of the waste, having pre-fitted the waste’s bottom end to the pipework.


To ensure that the tray is completely level all the way around, use a spirit level.

This is one of the most important steps in installing a shower tray because an uneven tray will cause drainage issues and water may collect on one side of the tray and potentially overflow.

Trays are designed so that water flows towards the waste outlet, eliminating the need to tilt the tray.


Check to ensure that all of the legs are engaged and that the lock nuts are tightened and touching the flange.

Pour a kettle or jug of water down the shower drain to ensure that there are no leaks or drips. Skirting boards or shower tray side panels can be used to fill in the gaps around the sides of the tray.


To cushion the tray and as a primary seal against leaks, run a bead of sealant behind the tray between the wall and tray. Apply a bead of sealant along the top edge and the wall.

Fit the tiles, leaving a 3mm gap between the tray and the tiles. Apply a bead of sealant between the tile’s bottom and the tray, ensuring that it penetrates the gap. This secondary seal is extremely important.


Cut the side panels to the desired length. Before presenting the panel, secure the leg clamps to the legs. To secure the panel, you may want to install battens on the floor.

Maintaining a shower tray after installation 

After you have installed your shower tray, regular cleaning can help to prevent the build-up of soap scum or limescale.

Rust marks can be removed quickly with white wine vinegar and baking soda.

To avoid mildew in your shower enclosure, use mould cleaning spray regularly. This will help to prevent mildew from appearing in your shower tray sealant.
