cracked tub

Hi guys,
My friend asked me for advice about his tub. It’s made of faux marble and it has crack on the bottom. The crack is approximately 12†long and ends at the drain opening. I do not know how wide is it (he patched it), but the water is seeping through. Is there any way, how to fix it – epoxy? He doesn’t have money to redo bathroom, he doesn’t care if the color won’t match.
Thanks Michal

There is no repair that I know of. The fiberglass flexs with weight, so any epoxy or patching material would pull apart and the leak would be back.
