Ideally, you'd want to remove the old tile before installing Avaire tile. However, we've seen some installations of Avaire tile directly over existing ceramic tile. You'd want to ensure there weren't any loose tiles, or high edges that would serve as a "lever point". The key is you need a flat and stable surface for a successful Avaire tile installation.
If you try it, please send us pictures "before", "during" and "after" the installtion to firstname.lastname@example.org
Thank you for considering Avaire tile!
