multiPANEL

I am going to use multiPanel for a walk-in shower.
Is it best to fit it to the wall before the shower tray or after
and butt it on top of the tray

With this kind of stuff, I'd fit it to the walls, then fit the tray. I would, however, use plenty of silicone to stick the tray to the boards. Without reading into it, I'm not sure how it fits together but if possible, put a small bead of silicone in the joints too.

Thanks gcol
It can lock together with a joining strip and a bead of silicone or you can pre-order it tongue and grooved, which I have done.

However I have just receIved a reply from multiPANEL and they say fit tray either way but recommend that you butt it on top of tray. As I am covering the whole length of wall it would be surely better to fit the board first.

The reason I suggested fitting the board first was just in case any moisture found it's way through a failed silicone seal on the tray/wall joint. It would soak straight into the end of the sheet where it was cut around the tray and cause damage.
As you have a highly waterproof wall surface, I think you'd be better fitting the wall first, then heavily siliconing the tray to the wall. If you can properly waterproof the joints, that should result in a bomb proof job.

Yeah that makes sense I wonder why they prefer the other way?

Probably female.
