What is the adhesive being used here? My plumber wants me to use expanding foam but iv always just used the same sort of stuff used here. Trying to find an example of foam being used
here you show the tray being fitted to plywood using a polyurethane adhesive, but in your installation manual, it says the Giorgio 2 shower tray should be bedded onto a sand and cement base if being installed onto a plywood base, which is correct?
If not done correctly, sand and cement can lead to cracking of the shower tray. You really need a plastic sheet laid first, this way the subfloor can expand or contract without forcing the shower tray to expand or contract with it. A lot of contractors use flexible mortar. The plastic sheet allows the floor to expand or contract, but leaves the shower tray free for that movement. Flexible adhesive is recommended and more and more contractors are now using it, instead of the sand and concrete mix. Just make you prime the concrete flooring first (SBR), otherwise the adhesive won't adhere to it.
No the good shower tray s have built in gradients to outlet you must however level all sides with long spirit level before adhesive or tile adhesive sets
Not many people install on new builds mostly it's just a replacement so not much good to most of us

What about fitting it on to floorboards that are already on top of joists? Is that possible if the floor is level?
So the shower tray is sloped so you don’t have to slope the whole tray yourself ?
Yes, so the sub-floor needs to be level.

That's why they are so expensive Always read instructions
