Questions we are often asked.

  • A swimsuit, a towel, and a waterbottle (no glass please!). We think sauna is more fun with friends, so you could bring a few of those if you’d like.

  • We highly recommend that you book your experience in advance. Walk-ins are welcome if space allows and up to 60 minutes before we close! 

  • Sauna makes people happy. And happy people spread joy. For us, that feels really important because healthier humans and more connected communities have the power to make a positive, lasting impact on their neighborhoods and cities. 

    But if we’re talkin’ brass tacks, research shows that regular sauna use increases healthspan, improves heart health, promotes muscle recovery, improves VO2 max, decreases the onset of neurological diseases, decreases feelings of depression and anxiety, and melts stress.

  • Of course! Sauna is for everyone and our team loves welcoming new people to Lost Language. We’re here to support you through your experience at your own pace. 

    Still not sure? Send us an email at hello@lostlanguagesauna.com. We’d love to answer your questions or meet you for a tour of our space.

  • Listen to your body! When you feel it, you’ll know…which is our way of saying sauna is not a contest and every day is different. 

    If you’re a “numbers person” and need a ballpark, we recommend 12-15 minutes in sauna, 1-3 minutes in cold, and 5-10 minutes to rest in between.

    But don’t forget our motto: Lost Language is a warm place for slow time. So don’t rush the process.

  • You’ve got 75 minutes to enjoy your time in our outdoor space with others, guided by our team. Lost Language offers guests two 15-person saunas (one woodfired and one electric), two communal cold pools, two outdoor showers, and plenty of space to rest and rehydrate. We have on-site changing rooms and off-site bathroom access, along with light refreshments and extra towels.

  • Wear what makes you feel comfortable…but ya gotta wear something! (Sorry, no naked sauna here!) We recommend a swimsuit or shorts and a tank. Bring a towel to sit on, too!

  • Our saunas are traditional Finnish saunas, designed by Cedar & Stone and built by our stellar team in Chicago.

  • You can bring water or sports drinks that help you stay hydrated. No glass bottles, please! 

    For safety and cleanliness, food is not allowed in the saunas or pools. Outside food is not permitted in our space, unless approved by a member of our team. 

  • At Lost Language, in-person connection comes first. Which means we’re a technology-free space.  

    Out of respect for our community — their experience and privacy – we kindly ask that you leave your phones near our check-in area. Guests unable to respect our no-phone policy may be asked to leave. 

  • You’re welcome to cancel your sauna reservation up to 1 hour before your visit. While we don’t offer refunds, you can gift unused credits to a friend or save them for use at a later time. 

    Private events can be cancelled up to 1 week in advance for a full refund or 48 hours before the day of the event for a 50% refund.
