Bringing the thermal experience to Fargo

The idea for Endure Thermal Spa was born out of a personal journey toward resilience and wellness. A few years ago, we visited Thermëa, in Winnipeg, where we first experienced the thermal cycle. The combination of sauna, cold plunge, and restorative relaxation left a lasting impression on both of us. The experience sparked our curiosity and opened our eyes to the profound benefits these practices could offer.

At first, the cold plunge felt like a challenge we weren't sure we could endure, but the immediate sense of invigoration was undeniable. Ethan loves the communal aspect of saunas, where conversation flows easily and a sense of community is fostered. I find a profound sense of balance and renewal in the thermal cycle.

Realizing how limited access to these services was in our own community, we felt inspired to create a space where others could experience the same benefits we discovered. Part of our motivation for starting Endure Thermal Spa was not only to share these transformative practices with the Fargo-Moorhead area but also to make them more accessible, for ourselves and for everyone seeking a path to enhanced well-being.

With Endure, we've set out to bring the restorative power of the thermal cycle closer to home. Our goal is to help others step out of their comfort zones, embrace new challenges, and discover their own strength through wellness. We can't wait to welcome you to our spa and share in this journey together.

Come endure with us.

You might be wondering...

Here are some frequently asked questions for those new to our spa and the thermal cycle experience!

Can I book online?

Yes, you can book directly through our website or the Wellyx app, whenever it's convenient for you. Not sure which service is right for your first visit? Give us a call or send a text, and we'll help you figure out where to start

How long are the sessions?

Plan to arrive 5 minutes early so you're not rushed. From there, it depends on what you choose: Contrast Therapy (infrared sauna + cold plunge) sessions run 45 or 75 minutes, Social Sauna is a relaxed 30 minutes, and Lymphatic Roller sessions are either a full 45 minutes or a quicker 30-minute Express Roll. There's no wrong length to start with, we can help you decide what fits your schedule and your goals

What should I wear?

For Contrast Therapy (infrared sauna + cold plunge), you'll want to wear a swimsuit, you'll be getting into the cold plunge, so that's the most practical option. Your session takes place in a private space, so there's no need to worry about who's around.

For Social Sauna, a swimsuit or loose, comfortable clothing both work well, whatever you feel most at ease in.

For Lymphatic Roller sessions, snug clothing like leggings and a fitted top works best, since it helps the roller do its job, and please remember to pull your hair back.

Beginners Guide to Cold Plunge

There's no need to dive in fast or prove anything to yourself. Start with just 30 seconds to a minute, that's a completely legitimate place to begin. Focus on slow, steady breathing as you ease in, and go at a pace that feels mindful rather than rushed. If you're working toward a specific goal, we're happy to help you build toward it. And for the best results, pair your plunge with heat beforehand. However you start, listen to your body, this is meant to challenge you a little, not overwhelm you.

Beginners Guide to Infrared Saunas

If this is new to you, ease in with a shorter session, 10 to 15 minutes is a great place to start. Drink water before and after, wear whatever feels comfortable, and settle in on the towels we provide. Let yourself breathe deeply and relax into the heat. If at any point you start to feel lightheaded, that's your body telling you to step out and cool down, there's no reason to push through it. We're always happy to walk you through what a good first session looks like for you specifically.

What happens during a Contrast Therapy session?

When you arrive, you'll get settled into your own private space. If you booked a 2-person session, you and your guest will be in that same private space together throughout. You'll start in the infrared sauna, where the heat helps you relax, boosts circulation, and eases tension built up over the week. Once you're ready, you'll move into the cold plunge for a shorter burst, this is the part that invigorates you and helps your body recover. Most people move back and forth between the two a few times over the course of the session, but there's no required pattern to follow. We'll walk you through how to pace it your first time, so you're never guessing what to do next.
