Circle Wellness Seattle

Circle Wellness Seattle is a private, self-guided thermal spa at 1326 N Northlake Way in Fremont, near Gas Works Park. Each booking gives one or two guests their own enclosed circuit built around contrast therapy. The circuit includes an open-air shower, a cedar soaking tub, a WellPod sauna with Himalayan salt walls and a heated floor, a step-down cold plunge and a heated riverstone bed. Audio cues guide guests through the session. Sessions run 90 or 120 minutes, seven days a week, and are priced per session rather than per person. Booking requires an account. Clothing is optional inside the private circuit, and guests may bring a swimsuit or robe. Towels and toiletries are provided. An annual Inner Circle membership is also offered.
