Behind the sink is pebble tile. This color would be similar to the one shown here. Great bathroom! I love the use of pebble tile. Beautiful space :) http://www.houzz.com/photos/3278064/Glazed-Quartz-Stone-Mosaic-Tile-contemporary-bathroom-tile-other-metro
island stone tile behind sin and can see in background, but color too light for us -- nice mirror
The cut out shower, the wood, and the tile. I like the sink!
