A half-bath is a type of bathroom found in many homes. Half-baths, or half bathrooms, include a toilet and a sink; however, unlike full baths, they do not have a bathtub or a shower. Half-baths are typically small, sometimes with just enough room for the sink and the toilet. Often, half-baths are located near a communal area, such as the kitchen or living room. Due to their location in areas frequented by guests, and because families typically don't use them as often as full baths, half bathrooms are sometimes called "guest bathrooms." In homes in which all the bedrooms and full baths are on the second floor, you frequently find a half bath on the first floor. Almost all homes with a half-bath will also include at least one full bath.
