Hi ! Look in the search bar for how to paint a tile floor . I have not done it , but I have seen quite a few tutorials on this site , where people posted how they did it and the materials they used . Some of the stenciled floors were gorgeous !!!! Good luck !

Depending on your budget. You can use Rustoleum or Homax tub and tile paint kit to paint them. Remove them and put on new tile. You can also lay large format tile over small format tile.

I recently painted my office floor and have loved the way that they turned out.

If you don't want to paint the entire floor, you could go with a bold grout color and some pretty rugs.

Another option is to go with a southwest theme and show case the flooring.
