The Japanese had invented the ritual of lying in the traditional Ofuro as a part of the daily bathing pattern to cleanse the body and calm the spirit. The bathtubs are a way of relaxing and rejuvenating your tired body. So the makers of this unique stainless steel tub thought of allowing you to pamper your body even more.

Steel Bath Tub
The steel helps to retain the temperature of the water. It is individually handcrafted in the U.S. and the seat sits 15″ from the bottom of the hand-buffed 3″ thick, double-walled metal tub. Three non-slip steps with a handrail provide access to the tub. Eighteen air jets built into the seat and sides of the tub provide streams of water that massage and soothe muscles; the jet system has three settings, controlled with the touch of a button. The features are absolutely luring me but the price of this steel plated tub is $20,000.
So this is one more luxury exclusively for the rich.
