A laundry room is a room where clothes are washed, and sometimes also dried. In a modern home, laundry rooms are often equipped with an automatic washing machine and clothes dryer, and often a large basin, called a laundry tub, for hand-washing of delicate clothing articles such as sweaters, as well as an ironing board. Laundry rooms may also include storage cabinets, countertops for folding clothes, and, space permitting, a small sewing machine.

In a building or ship, a room is any enclosed space within a number of walls to which entry is possible only via a door or other dividing structure. The entrance connects it to either a passageway, another room, or the outdoors. The space is typically large enough for several people to move about. The size, fixtures, furnishings, and sometimes placement of the room within the building or ship support the activity to be conducted in it.
