The Red Door Spa at Wildwood is about to get some serious competition: Woodhouse Day Spa, a Texas-based chain with more than three dozen locations nationwide, is on its way to the North Bethesda Market on Rockville Pike. The 6,000-square-foot spa will open this fall with a wide range of services from massages and mani/pedis to facials and “sleep treatments” (guided naps with aromatherapy and heated herbal compresses). The spa should mix well with some of the other health-oriented tenants at North Bethesda Market, including Whole Foods and Seasons 52
