The tile is attached to sheetrock and I don‘t want to damage the sheetrock by ripping off the old tile.
NO!!!! the top tile will crack if you do that do not do that it will be super expensive to get it fixed
if the tiles and grout aren't cracked at all then you'd be fine to just tile over it.. just make sure the doors will still close etc :P
your better off ripping the old tile off, if you rip the bottom of the sheetrock off you should cover it with trim besides trim will make the tiles stand out more
I definitely wouldnt recommend tiling over tile. Thats asking for trouble. It would be much better in the long run to just pull up the tile and sheetrock. Maybe you can jigsaw the part of the sheetrock where the tiles are at that way you can salvage what sheetrock you can. Then re-sheetrock where the tiles were at and tile away. To tile over tile is just bad work and you would probably have to do it anyway. Might as well do it right the first time and get it overwith. =)
