A shower head (40) has a passageway for a flow of pressurized air from a pressurized air supply, via a Venturi (48) having a convergent portion (46), throat (50) and divergent portion (52), to a shower discharge opening (56), and a passageway (58) for a flow of water from a water supply to a water discharge opening (60) in the Venturi. The Venturi is such that, in use, the general direction of the flow of air is turned through a substantial angle in the Venturi. This folding of the Venturi enables a compact configuration of shower head to be provided.
