Designer has asked me to cut the tile for shower floor out of main floor's tile. The area is 37"x 66" or 2442 sq in. Divided by 4 (2"x2" tile)= 610 tiles minus 1/8" grout joint of 152 tiles = 458 individual tiles to place. 
2 1/2" tile size =488 minus 122=366 tiles to place.
The question is should I glue the tile to a backing or set individual tiles? Seems like a PITA either way.
