King Spa and Sauna Chicago

King Spa and Sauna Chicago in Park City is a compact day spa built around one ritual: heat, then cold, then rest. The Nordic dry sauna runs at 198°F, cedar-lined, and guests can stay in as long as they like before stepping into one of two plunge pools set at 40°F or 50°F. Staff walk first-timers through the whole cycle, so no prior cold-plunge experience is needed.

A day pass costs $39 for a single one-hour session and includes access to the sauna, cold plunges, infrared sauna, red light therapy, towels, filtered water, electrolytes and tea. Walk-ins are welcome, and there's also a monthly Avanto Pass for unlimited visits, a five-day visitor pass, and discounted memberships for students and first responders. Private buyouts of the space run from $300 and can host up to eight people.

Hours split into two blocks on weekdays, 10am to 2pm and 4pm to 8pm, and run one longer stretch on weekends, 9am to 7pm. The setup suits solo visits or couples doing a few rounds of hot-cold contrast together, and reviewers mention clean facilities and staff who explain the process before you start.
