I bought 2.5x6 inch tile for a backsplash in my kitchen. The tiles have bumps that act as a "built in" spacer. The gap is very small, maybe 1/16". I am assuming I grout, but with what? Is there a special grout for glossy ceramic tile. I was thinking non-sanded to prevent scratching but I am not sure. Also, the tile is a beige color. Do you typically grout subway tile with white or is it a matter of preference?
