Nice choice of tiles. If I may add my two cents, I would strongly recommend using a dark grout with those tiles. I used the same tiles to redo my shower and they lost all their character when I made the mistake of using white grout. You really need the contrast of a darker grout to appreciate them.
I have been thinking about that. I did get ultra white for the grout, but have been questioning it ever since. I was thinking maybe a light silver, so would still be in the white family but make the tiles pop.
