Looks great! Is that tumbled travertine tile? If so, one word of advice....go with a neutral grout like bone or muslin, because any darker doesn't work well. I had to re-tile my keezer, because I tried to use the same color grout that I used for my slate floors and it looked like crap. Also, once you grout it give it a few days and then make sure to seal the entire surface with a quality stone sealer. Nice work! Post some pics. of your first pint! Did you get my PM response about the carbonation procedures?
