Abstract: A sanitary fitting for a washbasin includes a water inlet, a water outlet, and a shut-off valve which is provided in a control cartridge and is connected to the water inlet via a supply line and to the water outlet via an outlet line. The control cartridge is supported by a bearing element which is capable of fastening the fitting to a washbasin. A housing is slipped over the bearing element. A cylindrical clearance for receiving the control cartridge is provided in the bearing element. The supply line and the outlet line are formed at least partially as ducts in the bearing element that open into the clearance. The control cartridge includes openings through which the shut-off valve is in flow connection with the ducts. The housing includes a through-passage which permits the control cartridge to pass therethrough into the clearance.
