I finally decided on a tile for our kitchen remodel. It’s a gray slate tile 12 x 24. I think it will look great with our white kitchen cabinets. Now I have to pick out a grout color. I don’t want too much contrast between the tile and the grout, but I don’t want the floor to look like one color either. Does anyone have a suggestion for an exact grout color that would go with the tiles? See attached photo. Also, my contractor asked how much space I want the grout to be. I have no idea what to tell him. 1/8”? 1/4”? 1/2”? What looks best with that size tile? So many decisions. Any guidance would be so appreciated. Thank you!!
