Backerboard tape question

Are you fitting panels to the walls rather than tiles?
Panels usually use corner trims that the panels slot into. Walls will need to be pretty square.

I used these trims for the panel to tray joint
Neat finish and a good seal.
Lots of options to ensure a good seal

Install the tray on self adhesive legs?? ... i.e. a riser kit?

Really hate to say it but if possible, please don't, riser kits are terrible things and they are not reliable longer term. Lost count of how many showers I've had to repair after a riser kit has allowed movement in the tray and the wall to shower waterproof seal has eventually gone. They do not support shower trays properly. You should really build a plinth so the tray will sit flat and steady.

What is the tray made of?

Hiya, yes a riser kit, not sure what material the tray is as I bought it ages ago now, it’s heavy and rough on the bottom, a bit like fibre glass.
The legs are self adhesive on one edge and screw to the floor on the other, not sure which order you do the install though.

I have some ply left if I need to build a plinth but would need more guidance

Most likely stone resin, but honestly, supporting a stone resin tray up on plastic legs isn't a great idea. Forgot to ask, how large is the tray?

With a riser kit the only way it is held steady is the wall to tray points with the silicone and over time that can easily be compromised. When in use the tray wants to move, especially when supported on plastic legs and the seal will go eventually. Seen it many times.

To have a good, steady tray ideally use 3"x2" CLS, or however thick that's needed to get the tray a suitable height above the waste run and provide a suitable fall for proper tray drainage. That's used to create a frame that's screwed to the floor/wall and then min of a 15mm WBP ply or OSB3 top goes on (cut to accept the shower trap and pipe connections). You could then use silicone and some of your tape and seal the edges where the plinth meets the walls. Then the tray gets stuck to the plinth underneath, around the bottom edges and and along all the wall contact points, push the tray in/on and smooth off the silicone that's squeezed out, top up any sealant especially at the corners and leave 24hrs to set. Once that's all set, your tray will be well seated and sealed.

You can then fit your wall panels with or without the added seal and then silicone again.

Thanks Madrab, sound advice. I am looking at re starting this project now. I will get some timber and build a frame. What does the tray get stuck to the wood on top of the frame with please?

Are there any good videos on building a frame please?

How do I work out how high the tray needs to be as the outlet pipe is already fixed and in place from the last install, what kind of connection do I need between my new trap and the existing outlet pipe please. The current pipe is just the end of the pipe, no connections or adapters etc.

Thanks so far.

I use a silicone adhesive and then silicone sealant at all the wall edges

Not of the top of my head, guess a good search about may help

You need to look at the trap you will be using, attach it to the tray and see how far the base of the trap and the centre line of the outlet is below the tray. The first will give you how high the plinth (top included) needs to be to provide clearance for the trap, if there is a floor below it.
As far as the waste run is concerned then you need to ensure there is a suitable fall on the run to allow the tray and trap to drain properly. 25mm per/m at the absolute min.

Thanks, do I need a tanking kit?

I would always recommend a tanking kit anywhere where there is going to be water and would say it essential where there's plasterboard and/or chipboard
