A shower head has a rigid body forming a pressurizable compartment having a downstream wall of composite synthetic-resin material having an inner face and formed with an array of throughgoing holes so that pressurized water in the compartment will exit therefrom through the holes. A unitary liner sheet of a soft elastomer has an outer face bonded to the inner face of the downstream wall and is formed with respective tubular nipples fitting in and projecting through the holes. Each nipple forms a throughgoing passage having an inner end opening in the compartment and an outer end opening outside the body. The liner sheet and integral nipples are molded in situ against the inner face of the plate forming the downstream wall of the shower body. The composite synthetic-resin material is a polybutyleneterephthalate and the elastomer is silicone or the composite synthetic-resin material can be polypropylene and the elastomer a thermoplastic.
