How to Prepare for Shower Tray Installation
Start preparing to fit your shower tray by drawing markings on the floor where you're planning to install it. You should also mark out where the joists are so that you can leave enough space for the waste pipe.
Remember to check the area beneath the floor too, to ensure there aren't any pipes, cables, or obstructions in the way before you begin cutting or drilling.
Have all your tools and equipment organised and always read the labels, especially on packets of mortar mix and sealant as how they are applied and their suitability for the job may vary.
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, although if in doubt ask someone who specialises in shower installations for advice:
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
Use an electric drill with two separate hole saw attachments, one sized large enough for the waste trap’s main hole and one for the pipework, and drill through the surface. Double check there aren't any pipes or cables running underneath the area before you start drilling.
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 seal 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 to mark out the minimum thickness required for your mortar ready for the next step - typically this is usually between 5–15mm, although always check the manufacturer's guidelines first.
Step 7
Create a thick mortar mix and spread it evenly over the area for the shower tray with a flat trowel. Once the mortar is laid, it will be hard to lift and manoeuvre the tray - if need be, you can attach glass suction lifters to the top of the tray. If the tray has any protective masking, you may wish to peel it away at the edges prior to laying into position, this will make it easier to remove completely once you've finished the job.
Step 8
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 down firmly so it sits in place on top of the mortar bed, before removing the glass suction lifters. Check with a spirit level that the base is level, or adjust accordingly.
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 and allow enough time for the mortar to fully set. Check manufacturer guidelines first, but this is often at least 48 hours, although some fast drying mortars are available. You can then tile the area, and also apply a layer of silicone sealant in the gap between the shower tray and the wall. This will help prevent water from leaking into the opening along the wall.
