For a simple look - Large white tiles - Kerry Phelan Design. Similar layout of our small bathroom with a floating sink! Would prefer a glossier finish to the tiles since we won't be tiling all the walls "wet room.
So going to institute this 'Clean your room' check list for kids! Laminate and use a dry erase marker. =) No more checking and rechecking - "Is my room clean yet, Mom?" Don't call me until the checklist is complete :)
