I love the idea of adding a whimsical flourish to a bathroom while hewing to a clean, traditional look. Case in point: the Pun Tile Collection from Ascot Studio (spotted on Trendir). Based in Sassuolo, the center of Italy's ceramic industry, Ascot Tile creates witty monochromatic subway tile embellished with subtly raised letters. Tired of white? The Pun Tiles are also available in several colors and in two sizes: 12.5 by 25 centimeters or 25 by 25 centimers. In North America, Ascot's Pun Collection is carried by Canadian company Stone Tile; contact them at (866) 669-1103 (toll free from North America) to order.
