-8- An aerated bath 26 is disclosed comprising a plurality of receptacles 10 on the outside of the bath, each receptacle being in communication with the interior of the bath through one or a plurality of openings 16, and fluid supply means 20 connected to some or all of the receptacles characterised in that the receptacles are shallow and of a relatively smooth internal configuration. Preferably, the internal configuration of the receptacles is a part spherical dish. The smooth internal surface reduces locations where moisture can be trapped. Preferably also, the receptacle is made from a material, especially a plastics material, which is hydrophobic which therefore resists wetting by bath water. The plastics material is preferably easily machinable, and tough and durable, and may be selected from known plastics materials of this type such as nylon, polyethylene terephthalate, and the like. In a preferred form of the invention, the receptacles 10 are outwardly generally cylindrical in configuration, containing the dish portion in their upper face 14. The receptacles can conveniently be adhered to the outside of the bath (or the outside of the inner skin of the bath where the bath is double skinned) by means of known available water resisting adhesives. Preferably, an orifice 16 is provided radially of the cylindrical receptacle communicating with the dished portion to provide the fluid inlet. A suitable non-returnable check 18 valve may be incorporated within the confines of the radial orifice to prevent water from entering the air distribution system. The valve mechanism may be one of various known types such as ball and seat mechanism, or of the diaphragm type, offering a very low resistance to opening in the direction of fluid flow and providing a good seal against any flow reversal.
