This may have been answered already or this may be the wrong forum, if so I am sorry.
I have an older home (about 100 years old). The bathroom floor is concrete or cement about 3 - 4 inches thick. It has small octagon shaped marble tiles on the top which are impossible to remove.
Question, does anyone know how to remove these tiles? If not, can I re-tile over the top of them? They seem pretty smooth and I am concerned about adhesion of the mastic.
Many thanks in advance.
