Hydrotherapy spa tubs have a long tradition. Historical records support the medical profession’s belief in the therapeutic value of water to relax, support, restore and mend. The Romans understood the effect of water, steam and massage in their public bath houses, and various other forms of Hydrotherapy arose independently in cultures ranging from the Far East to the Americas. Later, a number of European towns established themselves as spa resorts but it was only in 19th century Germany that public spas were first opened in significant numbers.

In the 1960s, a visionary Californian engineer made a significant advance in the field of Hydrotherapy spa tubs when he invented a method of mixing water jets with air. The combination gave the resulting jets both force and direction, thereby replicating many of the effects of traditional manual massage. What differentiated this system from other, earlier approaches was that it gave users the ability to direct the jets, at any given temperature, upon the soft tissues and muscles that most benefit from massage. All the while, the bather could remain relaxed and comfortably reclined.

Thus began the spa tub, now produced worldwide in its millions: for relaxation, for recuperation, for improved mobility and, of course, for simple bathing pleasure.
