The hot tub is made of Lucite Acryl for durability and easy cleaning. Ergonomically designed seating literally encases the body. The jets in a Emaux spa are strategically placed to massage the varied trigger points of the body, from the neck, to the back, to arms all the way down to the soles of the feet. Hydro-massage relaxes muscles and relieves pressure on nerves; it increases blood flow to sore or damaged tissue. Buoyancy reduces body weight. Therefore, relieving pressure on joints and muscles, this allows you to move more easily.
