    ive raised my bathroom floor with joists and laid 12ml ply on top,
    now im worried that it won't be strong enough to support the bath...
    the bath has 5 supports, 1 inch circular, is there a chance when the bath is full that they could break through the ply?
    thanks in advance!

    15mm would be the minimum depending on the distance of the joists, even better would be 22mm.
    If you have already laid the 12mm ply it will be fine to lay the difference (9mm) straight on top. Just make sure you fit the second sheet so that the plywood joints do not match up. This minimises the risk of the floor tiles cracking.

    Tbh There is a couple of ways to install a bath and the load should be evenly dispersed between the feet and the frame so the bath does not belly. However you are not asking this so i will stick to the issue.

    If your worried that the ply will not support the weight simply adjust the feet up word and slid a pce of wood in under them.

    If your worried about that wood sliding then the bath was never secure enough to begin with.

    Sounds like a good idea just be careful that bringing up the height does not interfere with any of the waste or soil connections especially on the 4" pan connector. The smaller ones are easy fixed but the bigger ones can be a diy bitch.
