We're doing a very small downstairs bathroom (appx 5.5x7) It will have a standup shower stall, toilet, sink. I wanted something casual but still classic - I was thinking 1920's look with hex tiles. It will be the own downstairs bathroom in a small traditional 1940's cape, so everyday use by the kids, guests etc.

What size hex tiles will work best in a small bathroom like that? And what color grout? I've recently seen dark grout more and more and I love it - but would that overpower the bath especially if I had tiny 1" tiles? I guess I'm looking for the perfect combination of the two - tile size and grout color.

thanks for any help and pictures!
