I wanted to remove three lines of bathroom wall tiles without distrubing other surrounding tiles. These tiles were fixed on cement around 5 months back.. now we can see cracks on these tiles (different color)..
in the tile section at homedepot they make a hand held grout saw that you can use to remove the grout from around these tiles once you do they you can gently pry up a little bit to remove the tiles, if they were set good they shouldn't come out in one piece so put something on the floor and in the tub so as not to chip anything.
Use a sharp pointed tool to scrape out the old grout. Insert a thin sharp blade like a putty knife under the edge of the tile at the top edge. Hit the handle with a small hammer, sometimes once you get the first one off the others come away easily and you won't damage the wall underneath.
Use a masonry bit and drill hole in the center of tile to be removed. The larger the hole the easier it will be to get tile removal started. Be sure not to drill deeper than the thickness if the tile you don't want holes in the backer. Then take a small chisel and tap firmly to start removing the tile. Be sure to protect the tub from damage from falling tile ann be sure to wear eye protection and gloves. Broken tile is very sharp.
hammer bust that tile in the middle of it. Remove pieces. Don't remove tile from edges or may damage neighboring tile.
