PortaSauna was created to bring the full power of traditional sauna therapy into the wild, without sacrificing performance, safety or comfort.
Whether you’re deep in the woods, on a remote beach, or simply in your own back garden, it offers an authentic, high-heat sauna experience that goes wherever you do.
At first glance, it might seem hard to believe that a portable sauna can rival the intensity of a built-in structure, but that’s exactly what PortaSauna does. With a triple-layer insulated shell, the HEX model holds heat even in freezing conditions. They've been tested it at –12°C, and it still reached a powerful 100°C inside, with plenty of löyly (steam) from the included stove. It feels just like the real thing - because it is.
Designed for outdoor wellness, anywhere
PortaSauna is made for the outdoors. It thrives in open spaces, far from noise, screens and routine. The setup is simple. Just choose a flat surface and give it around 120cm of space from nearby buildings or trees. It’s a popular choice for home use, but just as at home at a campsite, festival or lakeside cabin. If you're using it on shared land, just check with the site operator first.
And don’t worry about the weather. The materials are rugged and built to last: Oxford 600D heat-resistant fabric, high-temperature TPU windows and a CPAI-84 flame-retardant lining. In windier conditions, you can anchor it with sandbags or use the included ropes and stakes to keep everything secure. When not in use, a waterproof cover helps protect it from the elements, although bringing it indoors during extreme weather will help it last even longer.
A safe space to sweat
Health is at the heart of PortaSauna. That’s why we’ve gone further than most portable sauna makers to test what actually happens to the air quality when things heat up.
Professional monitoring has confirmed that there’s no off-gassing, no hidden toxins and no dangerous build-up of carbon dioxide or fine particles. The air inside stays safe to breathe, even at high heat, giving you the peace of mind to fully relax. Unlike some modified tents or budget options on the market, PortaSauna is purpose-built to be a wellness product, not a camping gimmick.
Real sauna heat. Real steam
The PortaSauna HEX uses a genuine sauna stove, not a makeshift heat source. That means you get proper Finnish-style steam, not just hot air. And because it’s a wood-burning system, there’s no need for electricity just dry hardwood (like birch or alder) and a match. After each session, simply empty the ash tray and clean the chimney every few uses to keep everything running efficiently. There's no fan noise, no complicated controls, just the quiet crackle of fire and rising heat.
Questions you might be wondering
Does it really feel like a “real” sauna?
Yes. It gets hot, really hot. And because the materials are designed specifically for this kind of environment, you get that full-body sweat and deep relaxation you’d expect from a built-in sauna.
Is it safe?
Very. Every material has been chosen and tested with your safety in mind. We’ve taken it through professional air quality tests so you can relax knowing there are no hidden nasties in the air you're breathing.
Can it handle year-round use?
Absolutely. PortaSauna is designed for all-season use—even in deep winter. Just like with any outdoor gear, storing it inside when not in use will help extend its lifespan, but the build quality speaks for itself.
What about families?
It’s safe for children to use under adult supervision. Just keep sessions short, and make sure they stay hydrated—kids are more sensitive to heat than adults.
Built for a better way to unwind
PortaSauna is for people who take their wellness seriously but don’t want to be tied to one location. It’s for those who find stillness in nature, those who chase cold dips in wild water and those who believe that health doesn’t need four walls.
If you’ve been curious about outdoor saunas but unsure whether something portable could really deliver, this is your answer. Simple to set up. Powerful enough to rival permanent builds. Safe enough to use regularly. And small enough to take wherever life takes you.
