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.
