A
utility room is a
room within a
house where equipment not used in day-to-day activities is kept. "Utility" refers to an item which is designed for usefulness or practical use, so in turn most of the items kept in this room have functional attributes. A utility room is generally the area where laundry is done, and is the descendant of the
scullery.
Utility room is more commonly used in
British English, while North American and Australian English generally refer to this room as a
laundry room, except in the American Southeast.
