A studio apartment, also known as a studio flat (UK), efficiency apartment or bachelor apartment, is a small apartment which combines living room, bedroom, and kitchenette into a single room.
These kinds of apartments typically consist of one large room which serves as the living, dining, and bedroom. Kitchen facilities may either be located in the central room, or in a small separate room, and the bathroom is usually in its own smaller room.
Studio, efficiency, and bachelor style apartments all tend to be the smallest apartments with the lowest rents in a given area, usually ranging around 300 to 450 square feet (25–45 square metres) in the United States, but considerably smaller in countries such as Japan, South Korea, and several European capitals.
In British usage, a studio flat has its own bathroom; a single room with cooking facilities. Traditionally, if a dwelling has a shared bathroom, it is known as a bedsit. This distinction is encountered less frequently, as are bedsits themselves (especially in large cities) due to the consequences of the Housing Act 1989 discouraging landlords from offering this type of - once widespread - accommodation.
A variation common in New York City is the "L-shaped" or "alcove" studio, in which the central room branches off into a small alcove that can be used for sleeping or dining.
Bachelor apartment, or simply "bachelor," is the common term in English Canada for any single room dwelling unit which is not a shared accommodation. A shared room, or particularly small bachelor, is sometimes referred to as a "bachelorette." Residents of the province of Quebec (most in French) widely use the term "studio".
Japan has an even smaller variation of the studio apartment known as the one room mansion.
