I plan to tear out old 13 x 13 ceramic tiles in a large open area of 1,000 sq. feet and replace it with 20 x 20 rectified porcelain tiles on a concrete slab. What is the smallest possible grout lines -- I would like 1/16, but I have been told that 1/8 is the smallest. I really like large tiles butted close together so is it possible to have 1/16 grout lines?
Thanks for responding.
You can try it if it's your house, but I'd like to watch and bring a few friends. The industry says 1/8" if the tiles are good quality rectified. But you may have one heck of a time with 20" and only 1/8" gap. 3/16" would make your installation much easier.
It comes down to how consistent the tiles are and the floor better be super flat.
