A shower head (40) has a passageway for a flow of pressurised air from a pressurised 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.
