Abstract

A lavatory has a lavatory bowl having an upper side on which a seat edge is provided and a lower side on which a base connection is provided, a dispenser for excrement bags that can be removed individually from the dispenser and secured to the seat edge with the aid of a vacuum, and a vacuum line that enters the lavatory bowl and a suction line. The dispenser has a receptacle for a stack of excrement bags that lie flat one on top of the other. The seat edge is provided with suction holes that can be connected to the suction line. The seat edge and the dispenser are moveable relative to each other and can be brought into a relative position in which the seat edge and the flat-lying excrement bags are parallel to one another, whereby the foremost of the excrement bags can be sucked out of the dispenser by negative pressure in the suction line.
