anything you adhere to that tile will only be as stable as the tile is itself.

if unstable or loose, the tile should be removed/repaired/replaced.

a bathroom can be a very high humidity area, especially in ones with a shower or tub, so i would not adhere anything to it becasue it sweats and gets condensation on it from the hmidity that could adversely affect the bond of any adhesives to it.

if you go over use mechanical anchoring means in adition to any adhesives.
