Oxygen Spa Studio, Chicago

Soft, flickering tea lights glow against Oxygen Spa Studio's white walls as trained therapists rejuvenate bodyscapes with more than 15 massage styles. In the absence of a formal reception desk, personal beauty butlers welcome guests and guide them through the boutique spa while a wall fountain provides a gently trickling soundtrack. Speckles of lush green plants break up the ivory oasis, and the spa's floor-to-ceiling windows fill the space with natural light and calming glimpses of the muted outside world and slow-motion battles between rival cumulus clouds. Amid private treatment rooms stocked with intricately tiled showers, therapists tend to tight tendons and achy joints with traditional techniques, such as deep tissue and myofascial release, peppering in aromatherapy, body scrubs, scalp stimulation, and toe-centric footwork to further encourage deep relaxation.
