Like every new part of The Joule—from its boutiques (TenOverSix, Traffic LA, and Taschen) to its new penthouse and suites—the spa is dazzling. And it’s big. Enter on the street level to the 8,000-square-foot, geothermal-inspired space and sign in to a cup of ginger tea and warm hand towel. You’ll then be led down the stairs, underground, to locker rooms and European temperature play areas, including steam rooms, saunas, ice fountains, experience showers (complete with touchscreen panels), and a unisex vitality pool with massage loungers. Signature treatments are kicked off with foot soaks in hammered copper bowls with the in-house line of aromatherapy oils. You can choose from a selection of treatment options, including the signature massage or facial, but we recommend booking ESPA Time. Select either body or beauty time and number of hours, then let your therapist guide you through selecting a customized lineup of services. If you book a service Thursday through Saturday, take a shower post-treatment and bring your wet hair to the salon for a complimentary glass of Champagne and a blow-dry.
