tried and trusted
a solution for sauna lovers
We used the sauna often. The bottles we brought in never quite worked—too hot, uncomfortable, or not built for the space.
So we made one that was. That’s how Sauni started.
Plastic wasn’t safe. Metal got too hot. So we made one that could handle the heat, without compromising on comfort, quality, or health. What began as a fix became a mindset. Moving forward, our goal is to keep serving the wellness community, bringing the best of the best in terms of health and longevity.
