I decided on a gorgeous Marfil Travertine porcelain tile for my bathroom floor which was 13x13 but now learned that it is sold out and only comes in 20x20. My tile guy would be setting it diagonally. will this overwhelm my bathroom that's roughly 6 1/2 feet by 8 feet going with this larger tile. I'm seeing more and more larger tiles in baths these days. I really need to make a decision.
