Choose the tiles you want to replace with new tile. Replacement tiles should be the same size as the tiles you are removing, and they should coordinate with other features in the bathroom.
Cut the grout around the tiles you are replacing using a rotary tool. We used the Fein Multimaster which loosens the grout without breaking the surrounding tiles (Image 1).
Use a hammer to break up the tiles you are removing, and discard the pieces (Image 2). Be careful when hammering the tile; don’t hit the pieces you want to keep.
