Does a resin tray need to be embedded onto a wooden floor.

[Corrado]

Hello
I had a shower tray installed yesterday - it is stone rsin and was installed directly on to the wooden floor.
It seems fairly stable but it has not been embedded in any way.
The installers said that there was no need and that it will be fine.
I am not so sure - what do people think?

usually bedded on a weak sand / cement mix
if its not fixed it will leak where it joins the tiles

They said it will be siliconed where the tiles meet the shower tray. Is it insufficient?
I also heard that they can crack if not bedded in. True? I thought these stone trays were really strong!??

wouldnt trust it myself

I would have thought that unless they've glued it in some way, that it could also be prone to side-to-side movement as well as moving with the floorboards when they bounce up & down a bit... worst possible case, someone steps in, slips on the base of it, and slides sideways into the upright side; generating quite a bit of force on the way, and easily dislodging an insecure tray.....

However, you would expect that the tray came supplied with manufacturer's instructions or installation advice; why not insist that your installer lets you see these, and ask him to convince you that he's followed these rather than his instincts?

Note also that the manufacturer may not honour any product warranty should the tray be installed contrary to their instructions.........

Thanks!
I insisted that the floor be repanelled with ply underneath and also that it was bonded. He used a whole tube of silicone to bond it. It now no longer moves and is absolutely level!
I can't stand it when people bodge jobs!!

Some makers instruct that the tray is bedded on silicone mastic, other than that they all have to be bedded on sand/cement, I always buy the ones with legs, cant be arssed with all that faffing about mixing and squidging .

this one didnt specify what it should be embedded with, tbh - it is built like a ship - just can't see how it could actually crack!!!

silicone is an easy way to bodge many jobs and cover up a multitude of sins. Still, I don't think you will find many people these days who don't use it. Its so flexible.

i have and still do bed down with silicone when there is a large area to bed it to (ie not just the edges)..making sure the floorboards are secure...
never had a problem...yet
