Sanitary fitting

Sanitary fitting (1, 3, 4, and 5) comprising an external housing (2) that has at least one housing section (6, 7, 30), said housing section (6, 7, 30) having an insertion opening (10) at an inlet side through which at least one functional unit can be inserted into an interior of the housing up to at least one insertion stop (18, 19, 29), a housing clearance (20, 21, 22) being situated upstream and/or downstream from the at least one insertion stop (18, 19, 29) in a direction of insertion, in order to accept a projecting part, which protrudes past the insertion stop (18, 19, 29), of the at least one functional unit, the fitting (1, 3, 4, and 5) is of modular construction, and that for this purpose the external housing (2) has at least two housing sections (6, 7) that can be connected with one another, into which a plurality of different functional units can each optionally be inserted up to the at least one insertion stop (18, 19, 29), and that the housing clearance (20, 21, 22) situated upstream and/or downstream, in the direction of insertion, from the at least one insertion stop (18, 19, 29) has a longitudinal extension that is greater than or equal to a maximum distance between the insertion stop (18, 19, 29) on the one hand and a front side, protruding into this housing clearance (20, 21, 22), of the functional units allocated to the respective housing section (6, 7, 30) on the other hand.
