    How to Prepare for Shower Tray Installation

    You can prepare for installing your shower tray by drawing markings on the floor around where the shower tray will go. You should also mark out where the joists are so that you can leave enough space for the waste pipe.

    You should also check underneath the floor where your waste trap is going to go to ensure there are no pipes or cables running directly underneath it.

    You also want to ensure that you have all of the relevant tools, safety equipment, and materials needed to complete the job before you make a start on the steps below.

    How to Fit a Shower Tray Yourself - Step by Step Guide

    Below are the steps that you need to take to successfully install a shower tray yourself:

    Step 1

    Put your shower tray into its correct position on the floor and then draw around it with a pencil. You also need to mark out the drain area. Then, check that the floor underneath the shower tray is level in both directions using your spirit level.

    Step 2

    You now need to get your waste trap and put it in position on the floor so that you can mark out the direction of the waste pipe. This needs to be in line with the direction of the waste pipe below the floor.

    Step 3

    You should now take two hole saws, one that is big enough for the overall hole of the waste trap and one big enough for the pipe. You will then need to drill through them using an electric drill and the two hole saws.

    That will give you a hole large enough to fit the waste trap and pipe into. Ensure that you have checked there are no pipes or cables running underneath this area before you do it.

    Step 4

    Test the size of the waste trap in the hole that you have cut to ensure it fits correctly. You can then install the waste trap onto the shower tray.

    Step 5

    Once you have completed the steps above, you should then paint the area where the shower is being installed using some waterproof sealer.

    Step 6

    You should now mark a line again where the tray will fit. You should also then put a mark on the wall on either side of the shower tray area, which is 8mm from the floor. This marks out the minimum thickness for the bed of mortar that you are going to apply in the next step.

    Step 7

    Create a mortar mixture that is quite thick and then lay it out evenly across the shower tray area ready for bedding the shower tray itself into it. Use a flat trowel to ensure that the mortar mix is layered out evenly. Now that your bed or mortar is in place, it’s difficult to lift and move the shower tray into position.

    To make this part easier, attach the glass suction lifters to the top of the shower tray. Before your tray can be put into position, you need to peel back the masking from each of the square edges. Don’t completely remove this just yet as it is protecting the shower tray. You just want to pull it back enough so that there is no masking along the edges.

    Step 8

    Then, using the suction lifters, pick up the shower tray and put it into position on the mortar base, using the wall as your guide. Push it firmly down into place on the mortar bed and then remove the glass suction lifters.

    You can then level the tray off using a spirit level. Be sure to check all sides to make sure it is completely level.

    Step 9

    Once your shower base is in place and level, you can then remove any excess mortar from around the shower tray using a trowel.

    Step 10

    You will then need to leave your shower tray for 24 hours so that the mortar has time to set. Once those 24 hours are up, you can then tile the area, and you can also apply a layer of silicone sealant in the gap between the shower tray and the wall. This acts as a shower tray seal so that no water can leak down the opening where the wall is.

    Can you fit a shower tray on a concrete floor?
    You can fit a shower tray on a concrete floor. The best course of action, in this case, is to go for a raised shower tray as this will avoid you having to cut through the concrete to allow space for the waste trap.

    If you want to know how to fit a raised shower tray, it is very similar to a lower shower tray. However, the underneath will need to be filled in much more. You can also use a shower tray riser kit to raise the tray up onto legs.
    How do you remove a shower tray?
    You should begin by shutting off the water supply and remove any obstacles such as shower curtains or doors that may get in your way. Unscrew any fixtures that may interfere with the removal of the tray. Use a screwdriver to loosen any connections between the tray and the wall or floor.

    Pry it carefully, trying not to damage the tray as you do. Once you have loosened it, you should be able to grasp it and pull it towards you which will then pull it away from the walls and floor until it’s entirely removed.
    How do I choose a shower tray?

    When choosing a shower tray, you want to consider the following:

    • How much room is available for the shower?
    • Would you prefer a low or raised shower tray?
    • How would you prefer your shower tray to be installed?
    • Have you taken a look at shower tray sizes to see which would suit your shower best?
    What can I do if the subfloor is not completely level?
    In this case, you should use a quickset mortar so that you can continue with the installation of the shower tray. It is essential that the floor underneath the tray is completely level.
    How do I clear a shower drain?
    You will need to unscrew and lift up the shower drain attachment. Then, put on some gloves and remove as much hair and debris as you can by hand. If there is still hair and debris that won’t move or is out of reach, use a wire hook and poke it down the drain to loosen and remove any remaining hair and fluff.

    Once you’ve removed as much as you can, pour some bleach down the drain and leave it for a few minutes, then pour some water in to rinse the bleach away. This should remove any build-up of soap scum from within the pipes.
