WC

You may know that “WC” is short for “Water Closet”, and is a term used in many countries around the world to refer to the bathroom.  It typically refers to a room with a toilet and sink, rather than a full bathroom with a shower and/or tub.  The Dutch often use these tiles in their homes to signify the location of the guest bathroom.  You will find this tile on the door to the small bathroom on the main floor.
