About this app

Lost Language is a warm place for slow time—in the heart of Chicago. Step away from the rush and into the restorative heat of our Nordic saunas. Whether it’s the scent of cedar, the refreshing shock of our cold pools, or the conversation that flows when phones are set aside, each visit is an invitation to slow down, connect, and feel fully present.

Our seasonal events and year-round offerings bring people together through simple joys and shared experiences. Some arrive for post-workout recovery, others for a quiet moment after a long week, and many for the kind of unhurried talks between rounds that turn strangers into friends.

With the Lost Language app, you can:

- Reserve sauna sessions and special events in just a few taps
- Browse our seasonal calendar and see what’s coming next
- Manage your bookings, memberships, and gift cards
- Stay connected with updates, pop-up announcements, and community news
- Learn more about the tradition of sauna

Lost Language is more than a sauna—it’s a neighborhood space built for relaxation, recovery, and connection. Our combination of heat, cold, and community atmosphere creates a space where stress melts away, circulation improves, and time feels unhurried.

Every visit is designed to help you unplug, recharge, and build meaningful connections away from the noise. Whether you’re seeking a reset, cold-water thrills, or simply a place to share quality time with good people, you’ll find it here—wherever the season finds us.

Download today and make time for slow time.
