"The sleek subterranean spa beneath the the Joule hotel offers both traditional and experimental spa treatments in a relaxing environment. Many of the facials use Tata Harper products; body treatments include Swedish massage, cupping therapy, and Thai table massage; and there are brow treatments from threading to microblading by local brow expert Rula Sharkawi. There’s a steam room with a giant amethyst shining in the corner (thought to encourage tranquility), a sauna, showers, and the Vitality Pool, a body-temperature pool with jets that gently massage the skin. Book a 50-minute or longer service and get a free spin, kickboxing, or yoga class at the neighboring Vital Fitness Studio. "
