I would like to put peel and stick on an already tiled floor. The tiling was well done so I don't want to tear it up. It's just ugly for my taste. How can I pull this off?

1. Clean it SUPER well. Then when you think it's clean, clean it even better.
2. Use primer. They make a primer specifically designed to make peel n stick's adhere even better.
3. Don't use the cheap stuff. Use the thicker, higher grade tiles.

We do this all the time. With a properly cleaned and primed tile floor, the better quality peel n stick tiles will last for many years.
