Bathrooms might be the smallest room in most houses but they’re full of special features that make bathing, dressing and relaxing enjoyable in the US and other western countries. There’s a real renaissance in bathrooms with lots of contemporary designs changing the look of our bathrooms, so keep your eyes open. You can learn more about bathrooms in our library, or here in the homeowner glossary.
As the world goes global, Americans are learning about different home styles around the world. For example, in Europe it’s common for the toilet to be in a room by itself and that’s what you call a water closet, not to be confused with all the other “closets” in our houses.
