The Spa and Fitness Centre at Four Seasons Hotel Chicago

The Spa and Fitness Centre at Four Seasons Hotel Chicago sits off the hotel lobby at 120 E Delaware Pl in Streeterville. It's a hotel spa in the upscale tier, built around six treatments, a fitness centre with Peloton and Precor equipment, and water features that include a 44-foot indoor infinity-edge pool and a whirlpool.

Treatments run from facials using 111SKIN's Intensive Collection to a seasonal ritual combining dry brushing, cryo stones, aromatic massage and heated poultices. The signature Mariposa Massage anchors the massage menu, and couples treatments are offered for two guests working with two therapists at once. There's also a late-night multi-guest option that pairs private pool and whirlpool access with pastries from the hotel's team, plus manicures, pedicures and personalized personal-training sessions arranged directly with the spa.

Access is both for hotel guests and via day pass, and the spa is family friendly as well as geared toward couples. A Family Spa Membership is also available for those who want recurring access; details are handled directly through the spa team rather than listed publicly.

Hours run 7am to 8pm every day of the week. Given the price tier and hotel setting, expect costs in line with a Four Seasons spa experience rather than a budget day spa. For specifics on treatment pricing, membership terms or booking the multi-guest evening package, contacting the spa directly at (312) 280-8800 or through the Four Seasons website is the way to go.
