    Hi Guys,

    Looking for some advice on the best way to build a platform to raise a stone shower tray, its approx 900 x 900mm and is damn heavy!!!

    Complicated to explain but due to the location of the waste, I really need to connect to it, however this will mean raising the tray by a good 6 inches!

    Assume wood will be the best way, but what type? Way of fixing securely to floorboards? etc; etc......

    Look forward to some helpful advice

    build your self a 6 x 2 wooden plinth with 18mm ply on top.
    mark and cut out access for the trap.

    Any more thoughts on this one guys?

    If I build a plinth out of 6 x 2 do I need to fix this to the floor boards or will the weight of the tray and would be enough to hold it all in place?

    Many thanks

    Another option is to use 100mm thermolite block set on a bed of sand/cement & then bed the tray on to that with the same mix, tap it down till it's at the right hight & level then leave to set.

    Forgiv my lack of knowledge, but whats a thermalite block? Is it like a breeze block? Are you saying to use half a dozen of these around the edges and middle of the tray and use the ply on the tray? Do I need to fix the ply to the tray in any way?was thinking something like gripfill!!

    Seco, your original reply to this was to build a 6 x 2 plinth, just trying to work out exactly what you mean by this, do you mean just build a frame out of 6 x 2 then fix the ply to it with a cut out for the trap, then just put the tray on top of this? Is it best to screw the frame to the floor boards as well?

    get 4 x 6x2 spaced at 300mm centres approx then use noggins to join to gether gives you your base.
    place 18mm ply on top and mark waste hole remove tray drill waste hole. but drill oversize as you don't screw waste to ply only tray.

    use what mi say to secure tray to ply sand/cement, silicone, floor tiles adhesive etc.
    and make sure you silicone the tray edges against the wall before placing tray in place.
    decide what your using as a plinth first as you need to make you 6x2 the right length.
