A portable bathtub unit that is capable of being moved at will to a desired location of use and that is devoid of plumbing connections to be connected to a water supply, said unit comprising:

• a bathtub for containing water, said bathtub having bottom and side walls, an upper peripheral flange, and bubble jet nozzles in at least one of said walls;
• a jacket receptacle having bottom and side walls;
• said bathtub being positioned within said receptacle and defining therewith a double-wall structure having between confronting respective walls of said bathtub and said receptacle a back accommodating space, a front space and opposite lateral side space, and said bathtub and said receptacle being devoid of water supply plumbing connections or fixtures;
• bubble-jet producing means for generating and emitting a jet of air bubbles into said bathtub, said means comprising an air blowing pump for drawing in open air and forcibly discharging such air, a pressure control valve for controlling the pressure of the air discharged from said air blowing pump, a pipe leading the air discharged from said air blowing pump to said bubble jet nozzles, a portion of said pipe being raised to extend to said flange and having an opening exposed therethrough and a cap removably closing said opening;
• a driving controller operably connected to said air blowing pump for controlling operation thereof;
• a filter unit for filtering water in said bathtub, and a pump for circulating water between said bathtub and said filter unit;
• a steam mechanism including a steam producing device for producing and supplying steam into said bathtub;
• a drain for draining water from said bathtub;
• injecting means for injecting a bath liquid or an aromatic into said bathtub;
• an illuminating means for illuminating said bathtub, said illuminating means including a light source spaced from said bathtub, an optical projecting means for emitting light into said bathtub, and optical fibers for transmitting light from said light source to said optical projecting means;
• a cord reel supporting a reeled electric cord operatively connected to said air blowing pump and to be connected selectively to an electric source for selectively enabling power to be supplied to said air blowing pump;
• said air blowing pump, said pressure control valve, said pipe portion, said driving controller, said filter unit, said steam mechanism, said injecting means, said light source and said cord reel all being accommodated within said back accommodating space;
• a control panel having a switch operably connected to said driving controller for selectively controlling operation of said air blowing pump;
• and
• damper leg stands mounted on said receptacle for supporting said bathtub unit.
