Hey 82, I just tiled my sisters house. Kitchen, dining room, hallway, unility room and both bathrooms, peice o cake. 16" on the square, wanted to do it on the diagnal but she wanted it that way, Started in the middle of the front room w/ 3/16 grout spacers and when i got to the sides it took an eight incher, very little waist. Did a quadrant at a time and continued the layout thru out the house. How do you like me now?
