Instead, the raw ingredients of beer — hops and barley — are combined with other herbs, selected by a master herbalist, in what French describes as a "giant tea bag." The result, she adds, is "efficient, healthy and pleasant." Customers of the Beer Spa can book a private room for one or two people and enjoy a four-step, self-paced treatment: bath hydrotherapy with the therapeutic hops, barley and herbs; an infrared sauna; a rain shower; and an outdoor deck. French notes that the ingredients offer the benefits of relaxation, invigoration and wellness from B and K vitamins and other nutrients for the skin. There's also a relaxation lounge with "zero-gravity" chairs, next-generation massage chairs designed to make you feel as if you're floating. French says she and Zouaoui discovered the chairs in Korea while on a fourteen-month tour of 25 countries around the world.
