I have 12 x 12 porclin floor tiles on my counter an back splash, set as close together as we could get them. very little grout line, wears like Iron, hot pans from stove top to counter, no problem!.have an extra deep sink love them both only change I'd make is an under counter mount sink, no edges around sink to keep clean and just wipe anything on counter into sink. Lg tiles cost me less than $2 each/
