Tile saws made by Dewalt,Felker,MK,Target,QEP,Ridgid and others had performed fantastic for cutting Avaire tile. Any of these saws with a blade designed to cut porcelain tile will cut Avaire tile in a single pass without the need to cut the tray seperatly.
Most saws have a depth adjustment, check to see if the blade is adjusted down far enough to cut completly through the tile and tray.
If you are still having problems let us know what type of saw you're using and we may be able to offer suggestions.
