My tiled bath tub panel seems hard to be removed. I could take off all 4 screws and cut throug the silicone and grout but it looks like the woodboard under the tiles also glued on the back. Please help.
From your description it suggests that you will just have to bite the bullet
and remove the layers until you obtain a sound surface.

I am sure other posters will have ideas. *This is a recent post*

Agree with tekkie. Rip away. Use chisels and putty knifes with hammer. It will come off.
For complete renovation use hammer and smash the **** out of it until down to studs and redo.
