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.

  • Water poured from a wooden ladle onto hot sauna stones, steam rising

    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.

  • A woman sits in a wooden cold plunge tub on a deck in the autumn woods, steam rising off the water

    Cold

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

  • Four friends in robes laugh together on a bench outside the sauna at dusk

    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.
