Quality
time

is unrushed
and deeply human

It’s familiar, grounding, and often “just what we need.” It doesn’t just feel good, it does good. And it reminds us that good people are at the heart of great experiences.

At Lost Language,
we make space for

that kind

of time

and the people who
want more of it.

Our space is warm and social: a place where connection builds community and rest becomes routine.

Think of it as a

thermal

practice

something that repeats, builds confidence,
but feels a little different each time.

When you’re in our space, how you sauna is up to you.
And we’re here to guide you if you need us.

our space

We’re an outdoor social sauna space built in Chicago by Chicagoans.

Experience quality time with others through alternating rounds of hot, cold, and rest.

Communal Saunas

Our 2 saunas each fit around 15 humans.

Our electric sauna runs Thurs-Sun and our wood-fired sauna heats up on
the weekends (Fri-Sun).

cold pools

Our 2 cold pools each fit
3-4 humans.

Take a dip alongside your friends and future friends. Our two outdoor showers are also a great way
to cool down.

If you’re craving some
slow time in a warm place,
we’d love to welcome you in
