Hi phil -
get your head under the bath with a torch, and get a look at the back of the bath that is against the wall. You should see a wooden support batten (you would if I fixed it!), or at least some kind of metal bracket. My fears are that there are neither of these there.
If the bath is full of water, and you get in it, it is a huge wieght to support - I even build a wooden frame round the sides and front of the bath as if you put all your wieght on a full bath front edge, with no support the whole lot could go through your ceiling.
If you need to use the bath, someone needs to fit a frame on it asap!
Good luck!
