Main Line, PA · Opening November 2026
Feel alive
Heat. Cold. Connection.
A wood-fired Icelandic sauna and cold plunge, coming to the Main Line. Reset your body. Clear your mind.
Try something new
Not a spa. Not a gym. A ritual.
Every session is a guided experience, led by a gus master. Step outside your comfort zone and into something you’ll feel for the rest of the day.

Heat
A real wood fire and hot stones. Your gus master pours, the steam rolls through the room, and for a few minutes nothing else exists.

Cold
Then into the cold plunge. Your breath catches and your head goes quiet.

Connection
Back outside, next to people you didn’t know when you arrived. No phones, no performance. It’s the part everyone comes back for.

Our story
What we missed most from Iceland.
We’re two Icelandic families who moved to Pennsylvania a year ago. At home, the sauna and the cold water are part of ordinary life. After work, after a swim, in the dark in January, with friends and with strangers.
So we’re bringing a little piece of home to the Main Line: a wood-fired sauna, a cold plunge, and the people you share them with.
