A toilet covering hinge assembly for mounting a toilet covering to the rear of a toilet for rotation of the toilet covering about a hinge axis between a lowered and a raised position. The hinge assembly includes a hinge element which is provided at the rear end of the toilet covering and is formed with a bore extending along the hinge axis. A hinge shaft extends through the bore in a rotatively fixed relation thereto so as to be rotatable together with the toilet covering about the hinge axis. One end of the hinge shaft is received by a support member provided on the side of the toilet for allowing the hinge shaft to rotate together with the toilet covering relative to the toilet. A retainer spring is secured to the hinge element adjacent to the bore for latching the hinge shaft against an axial movement thereof. The retainer spring comprises an outer section and an inner section having an inner edge projecting radially inwardly into the bore and capable of being resiliently deformed into and out of locking engagement with a stepped shoulder in the outer surface of the hinge shaft.

A bubbling bathtub system including both a large bubble generator, which blows relatively large bubbles into a bathtub, and a minute bubble generator, which functions so that bath water with air dissolved therein by pressurization is sent to the bathtub to produce minute bubbles in the bath water, connected to the bathtub. The relatively large bubbles produced by the large bubble generator and the minute bubbles produced by the minute bubble generator cooperate to enhance the good feeling produced during bathing. Both or either of the relatively large bubbles and the minute bubbles can be optionally produced as the user desires for optimum effect.
