Abstract: A plurality of receptacles are provided each having pockets for receiving a bottle containing a shampoo or hair conditioner to be warmed. Each receptacle includes a U-shaped water conduit having a pair of legs extending beyond one side wall thereof. The bight portion of each conduit is closed by a spring loaded flap valve extending parallel to the bight. An opening is provided behind each flap valve which is in line with the legs of the U-shaped conduit. A first receptacle is connected to a pair of openings in a master heating unit containing a thermostat, a heating coil, and a pump for pumping water from a source past the heating coil through one of the openings in the U-shaped conduit of the first receptacle and back to the other side of the pump through the other leg of the U-shaped conduit in the first receptacle, warming the contents of the bottles supported within the first receptacle.
