This is what we found on Wikipedia regarding the Cloakroom:

A cloakroom, known as a coatroom and checkroom in North America, is a room for people to hang their coats, cloaks, canes, umbrellas, hats, or other outerwear when they enter a building. Cloakrooms are typically found inside large buildings, such as gymnasiums, schools, churches or meeting halls. In private homes, hatstands fulfill a similar function. In the UK, a cloakroom may also refer to a lavatory.
