    This kit has a number of plastic screw adjustable legs with are screwed to plastic discs which are fixed to the underneath of the tray by self adhesive film.
    As it is 1000mm quadrant I wont be able to access the ones furthest away if adjustment is required.
    I'm considering whether to stick all the legs to a shaped plywood sheet first, carrying out adjustment if necessary and then place the heavy tray on top on a bed of gripfill or similar
    The other alternative would be to build a timber plinth and to not bother with the legs at all.
    What would be the advice on this problem?

    If in doubt construct a plinth. I had an issue with something similar which had double sided foam patches. Trouble was the foam didnt compress fully until somebody stood on the tray.

    bin the legs and build a frame either 3x2 or 4x2 and water resistant ply on top and then your golden, then just add some cloaking trim or finish the front off how ever you would like

    Thanks - I will build a plinth, I don't trust that leg system with that weight.
    I'm wondering if I should seal the the wpb ply board with primer G and bond the the tray on top with unmodified thinset such as keraflex S1 - after all it is like a big tile

    good choice, and yes any flexible tiling adhesive will work fine never used primer g on ply myself but cant harm if you have any left from doing the floors

    I'm with ShaunCorbs on this one apart from the Primer g as I have never used it myself.

    I did an 800 quadrant tray a couple of weeks ago on those legs, wasn't keen but seems alright, could reach the back ones OK with a bit of extravagant contortionism.
    I was in the bathroom for a few days as wasn't just doing the tray and for a couple of days every time I had a feel of the legs they needed extending a bit, must have been the foam squishing.

    If I knew before I started doing this job that I had to be more flexible then the missus. I'd have quit before I started.:p:p
