Yes, an all white tile floor is a nightmare and shows everything. Couldn’t wait to get rid of mine. But....maybe you are the type who likes to clean daily.

I have silver floor tile with light silver grout. Love it. Yes there is still hair and dust but it doesn’t scream out at you.

Anything with some slight variation in color will be infinitely easier to maintain than any solid color, especially white or (horrors!) black.

The grout choice for the green tile depends on if you want the individual tiles to jump out at you or for it all to blend in a more seamless look. I'd prefer a very light grey, I think, but pick your floor tile first. Are you using grey grout for the white shower tiles? One thing always affects everything else.

Yes, I think a grey grout for the white tile. I live the green tile and wanted it to be the focal point but I may have gone too far with white.

Agree. I'm remembering a beach-front condo we rented once. The white floors in the kitchen and baths were lovely when we arrived -- less lovely over the course of the week.

Love the charcoal grout with the mint tile!
