Hi we have an old shower and in removing the tiles, the bottom pieces were cemented onto the cindblock.wich is the part of the house structure.
We are using a chisle and hammer but its not taking off the center pieces of the tile. Any suggestions as to how to remove these tiles?

D Are you using a masons chisel? They have a broad blade for things like tile. Just be careful not to damage the block, they can be fragile.
