About Onyx Day Spa

Onyx Day Spa pampers visitors from head to toe with an array of rejuvenating treatments. While technicians administer deep-cleansing and hydrating facials in one room, massage therapists tend to sore muscles in another. To round out its services, the spa also offers custom mani-pedis and exfoliating body wraps.
