Avaire tile is cut with the same tools traditional tile is cut with. An angle grinder with a diamond blade designed to cut porcelain tile or the Roto zip both work great for cutting Avaire tile and both will cut the tray with no problem. To make straight cuts you can either rent a wet saw or use a tile cutter and after snapping the tile gently fold back the tile exposing the plastic tray and carefully use a utility knife and score the tray a few times and continue to fold it back untill the tray snaps.
Hope this help. Let me know how it goes.
