ABSTRACT OF THE DISCLOSURE An improved air-bubble massage appliance having a control unit which may be placed anywhere within reach of the person in a bathtub, without danger to him, such that he can operate the appliance without getting out of the bathtub. Known similar appliances have the control-unit connected directly to a power outlet. As a result, the control-unit must be placed out of the reach of the person in the bathtub for safety reasons, thereby preventing adjustment of the appliance during use. These drawbacks are overcome according to this invention by pro- viding a mains transformer producing a low-voltage, the trans- former being accommodated in a separate mains-supply unit in such a manner that the said transformer is shielded from spray. The housing of the said mains-supply unit, enclosing the said mains transformer, is adapted to be connected, by means of a power cable, to a power outlet. The low-voltage is adapted to be transferred, through a connecting cable, from the housing of the mains-supply unit to the control-unit housing. The devices accommodated in the said control-unit housing are adapted to be driven by this low-voltage. Since only this low-voltage is applied to the control-unit housing, even if the unit falls into the bath, there is no danger to the person therein. Nor is it necessary, for safety reasons, to have the control-unit housing permanently installed. Only the small mains-supply housing, with the transformer, must be permanently installed out of reach of the person in the bath.
