The tile itself is beautiful but the calculator is totally off  . I needed a little more than 13 sqft and the calculator said 1 package is enough (as it contains more then 14 sqft) .... Well, its only 10 pieces in it and they are 1 sqft each! Sadly I only realized when I had 2 pieces on already... now I cant take them off without damaging the wall and Im 4 pieces short... Please fix the calculator!
