Removing ceramic tiling from either a wall or floor requires a hammer, a chisel, a bully tool and possibly a sledgehammer, depending on the size of the job. The cleanup after removing the tile may require other tools, but this is all you will need for the actual removal of the tiles.
The first thing that needs to be done before removing ceramic tile is to clear the area of any molding, door frames or doors to ensure that they do not get damaged or get in the way of the work. The next step is to create an entry point underneath the tile. If there is a natural edge to the tile that is easy to get under, that is the best option. If not, start by using either the hammer or sledgehammer to break a section of the tile and pull the pieces out. Once there is an opening underneath the tile, slide the chisel or bully tool underneath the tiles and begin to slide it underneath the tiles. This will take a fair amount of leverage to separate the tile from the floor. Continue to slide the chisel or bully tool along the floor until all the tiles have been lifted. After that, simply discard the old tile, and the floor will be ready for whatever new flooring is going to replace the old tile.
