Abstract: An insulated bed bath construction 10 including a thermally insulated dual reservoir basin member 20 which cooperates with a main lid member 30 having a pair of apertures 32, 33 which are alignable with the pair of liquid reservoirs 24, 25 and wherein each of the apertures 32, 33 is provided with a closure unit 13 adapted to sealingly engage the respective apertures 32, 33 to minimize thermal losses from one reservoir 24 when the other reservoir 25 is being accessed through its aligned aperture 33 during the bathing process.
