Where Therapy and Relaxation Meet
Step away from the city for an hour. Step into a space designed to slow you down. Our licensed therapists deliver clinical-quality bodywork in an unhurried environment whether you're booking a deep tissue massage on a lunch break, prepping for a special occasion with a facial, or unwinding in our infrared sauna and salt therapy lounge.
Services Offered at Our K Street Location
Massage Therapy
Swedish, deep tissue, prenatal, and more. Choose 60 or 90 minutes; your therapist tailors pressure and technique to what your body needs that day.
Intuitive Massage
A therapist-led session where pressure, technique, and focus areas adapt as your body responds. Ideal when you want your treatment to go where it needs to go rather than follow a fixed protocol.
Esthetics
Customized facial treatments designed to restore balance, hydration, and radiance to your skin while creating a deeply relaxing self-care experience.
Medical Massage
Targeted bodywork for chronic pain, injury recovery, and limited mobility. Often used alongside care from your physician or physical therapist.
Halotherapy Chill Lounge
