How to Remove Floor Tiles?
The best way to remove a tile floor is to scrape the grout away between the tiles first. You can do this with a sturdy screwdriver, or they sell a grout remover tool at the hardware store. Once all the grout is removed, you can slip a scraper under the tile and gently pry the tile up. You will probably crack a few doing this, but it is the only way to get them up sometimes.
