I did a small bathroom 5x10 and tiled the floor and shower walls. I used the exact same tiles for the floor as the shower and everything was set with 1/8" grout lines. I dont want to buy two separate types of grout as i think i can get the whole job done with one box.
As I understand the rule is: unsanded for 1/8" or less, sanded for greater than 1/8"
Can anyone attest to that?
I am almost done my basement, just in time for posting season
