What are the brands of those tiles? Shaw Midori, by chance? I ask because I have some bathroom tile that looks similar to the first one, and I could photograph it for you if it was. what color do you want to bring out of the bianco antico? (grey tones or brown tones?) I really do not like the second tile from that photo. It looks like it competes for attention too much (like the last poster mentioned.) The third also looks, to me, like the color wouldn't match..... but I'm not sure what overall colors you have. I just remember the bianco antico I looked at would match brown tones better. Last comment.... my floors are dark wood with white cabinets and black countertops. The floors did not darken the space or make it too dark. Since the cabinets are white, it still is a very bright space. The floors just contrasted that and maybe made them seem even brighter...

Don't choose a grouted vinyl for a wet location. Choose sheet, or locking.

Select the floor that is closest in color to the knots in your woodwork.

I really like the colors you have already although I would probably have more gray in the floor with maybe a little black also to pull in that countertop. I don't know about the type of floor. That is a subject I am debating for my own remodel of kitchen and great room.
