Installing a walk in shower tray in 4 steps
1. Preparing the surface
Stripping the surface
Putting in the drainage system
Take precise measurements of the position of the plughole or outlet of your shower tray, so that you can factor this in when stripping out the flooring. Put the drainage components in place and connect to the outflow pipe. Generally all the components will be made of PVC and assembled by gluing. Once the glue has dried on your drainage assembly, test the seal by letting some water flow into the waste.
The drainage system needs to be held in a cavity underneath the tray, with enough space to work around the waste for any potential future repairs.
There are two options:
- dig deeper than would be necessary for the shower tray alone in order to create an open space for the drainage parts. You can then build a special support frame for the pipes and waste or use a riser kit;
- cut a special channel in the floor material to accommodate the drainage parts.
2. Positioning the tray
Once the mortar is dry, you can set down the tray. Check that it's perfectly level and has contact with the layer of grout across its entire surface.
3. Fitting the tray
Since this is where you will permanently secure the tray, make sure you connect the plughole and waste correctly. Apply even pressure across the tray once in position to assist adhesion and check that it's level using your spirit level.

I'm a trained electrician who started off working in large-scale industrial projects. Most of my early career was spent taking on huge electrical installations. I like to think that no job is too big for me, and after all the experience I'd gained, I started managing teams of electricians.
I like to learn on the job, so around ten years ago, I moved into building and construction. As a site manager, I've overseen the building of small residences, sport facilities, and even theatres!
Working with my hands is something I love to do in my free time as well. For four years now, I've been restoring our home in the Welsh countryside. I even built a conservatory for my wife, who loves watching the sheep behind our house.
Whether it's patios, interior design, roofing, plumbing or electricity - I love giving it all a go! I've even made my family DIY converts and together we've built almost everything we have from scratch. My experience, both in the field and in my workshop, has taught me a lot and I'm happy to share what I've learned. No matter how big or small your project is, I'm here to answer your questions and help you choose the right tools and equipment.
