Complete with its own line of locally-made spa products, Thann Sanctuary Spa focuses on natural therapy in a soothing, cool-gray atmosphere. Thann's "Nano Shiso Therapy" uses purifying seeds and revitalizing mushroom extracts suited to your skin type, with a massage of your choice: aromatherapy or Swedish. Or try the Sanctuary Signature deep-tissue massage, which uses palm strokes and thumb pressure to relieve muscular pains.
