Here are a few 'before' pics:
And here is the bathroom NOW!
The floors and shower walls are 16x16" multi-colored slate. Shower floors and tub wall are stone mosaic tiles. Vanities were custom made, sink vessels and faucets were purchased here, and walls were painted in Behr's Graceful Gray. It looks pretty darn close to the inspiration picture, doesn't it? Mission accomplished and we couldn't be happier.
