My initial reaction is, - - Don't do it!, - - but maybe someone else knows better. Should be interesting.

It really goes against the grain.
As a pro I would say do not do it.

But if you attempt, you will need to rough up the surface to accept the thinset.

tile on fiberglass, as said before, don't. I only see one huge headache to be followed by another.

On the fibreglass I agree with the rest of them: don't do it, you'll be back! On the marble, you're better to take it out, check the underlying structure vis-a-vis deflection, thinset/screw some cbu down, then tile. Don't EVER use mastic in a situation where the tile might experience water. It turns into toothpaste which doesn't hold tiles down well :cheesygri Rich.
