Setting shower tray on silicone - what about the rim?

[Mike Armstrong]

It seems from the google archives that quite a few of you have bedded a stone resin shower tray on silicone. Question is, did you run a thick bead all across the base area and rely on the weight of the tray to flatten it out. If so, what about the rim? I suppose one could just run one single bead where the rim will go. The tray would have to go down very accurately 'first time' for that to work. Any thoughts?

Also, I was going to floor tile the en-suite but we have since decided to use laminate (floormaster aqua loc). I was going to fit the tiles up to the shower tray but sit the sink/pedestal and toilet on top of the tiles. Would you still take that approach with laminate flooring or is there too much 'spring' in the laminate/underlay for this to be practical? Sense is telling me to fit around.

Thanks

I considered silicone but decided to follow the manufacturers advice and used mortar, ... pretty straightforward and it supports the rim.

The manufacturers say use mortar. So that is what I did.

I fitted mine underneath the toilet. Not a hint of a problem in that respect and looks far neater. Fitted onto the "green" fibre board underlay.

The main mistake I made was not glueing the boards together. Despite its name, the floormaster aqua loc is NOT water resistant unless you glue it as well. Luckily, I moved house quickly enough to not have to deal with the consequences and the new buyers never noticed the laminate lifting.

Manufacturers don't no jack. Silicone for success

Well my mortared one has worked fine, and in complying with the manufacturer's instructions I've retained their x-year guarantee on the product. Whereas you haven't.

Actually, the manufacturers instructions for my shower tray 'durastone' specify either mortar or silicone. Their technical line was next to useless when I asked them this same question.

Interesting to note that the 3 shower trays I used (Just Trays) all specifically forbid the use of Silicone - stating Guarantee was void is it was bedded down on anything other than weak mix mortar ... so I followed their advice.

These wouldn't be the same manufacturers who make bath wast connections that don't work without silicone either would they? Don' believe all you read from manufacturers. Do you honestly believe whe your shower tray cracks in 4 years time they are going to come an replace it for you re- do all your tiling and grouting, redecorate th room below? fit things properly, it's your house not theirs
