“I am more comfortable bathing naked, regardless of who I am with”, writes author of Sweat, Mikkel Aaland. But that doesn’t go for everyone.

We're thrilled to introduce the official International Sauna Congress 2026 sauna hat — a limited edition piece of wearable congress history, crafted exclusively for ISC26 attendees.

Here's the best part: if you're coming to ISC 2026, you don't need to worry about postage. Pre-order your hat now, and it'll be waiting for you when you arrive at the congress in September. Easy!

We're excited to announce that Sauna Channel is joining the XIX International Sauna Congress this September in Oslo as an official partner. 

The American production company has spent the last several years documenting sauna and bathing cultures around the world, and will now bring that work directly into the congress — screening films inside the Árdna sauna at SALT, premiering a new documentary about the Norwegian badstue boom, and producing a short film for the grand opening ceremony at Oslo City Hall.

Thank you to congress sponsor, Marinbastun! Founded in Sweden in 2012, Marinbastun was born from a simple conviction: floating saunas deserved better. With a Finnish founder, 15 years of marine production experience, and a deep love of sauna culture, the company set out to craft floating saunas that were as functional as they were beautiful.

Thank you to congress sponsors, North American Sauna Society and Finlandia Foundation National!

The North American Sauna Society, in cultural partnership with Finlandia Foundation National, is honored to support the International Sauna Congress as nonprofit sponsors—joined by a shared conviction that sauna is more than a trend, more than a wellness amenity, and more than a moment. It is a practice as old as community itself.

Thank you to congress sponsor, Nordic Sauna.

Nordic Sauna designs and builds custom sauna, steam, and wellness environments for residential and commercial projects. Our work focuses on authentic sauna principles, quality craftsmanship, and creating spaces that support relaxation, recovery, and connection.

Thank you to congress sponsor, Nordic Hotels & Resorts.

As a proud sponsor of ISC26, Nordic Hotels & Resorts is transforming the industry with conscious luxury and a lust for exploring. With our expansive collection of independent resorts and retreats, supporting this congress is both a natural responsibility and a profound source of inspiration.

Thank you to congress sponsor, HUUM.

HUUM is built on a simple belief: a great sauna heater should be the centerpiece of every sauna, not just for the heat and steam it delivers, but for the way it looks standing in the room. Good design and a great sauna experience are inseparable.

The world’s largest sauna event is five months away—and we’re looking for enthusiastic volunteers to help us deliver the best International Sauna Congress yet. This is a unique opportunity to be part of a global gathering that celebrates sauna culture, innovation, and community!

When you’re coming to Oslo for the International Sauna Congress in September, don't just come for the Congress — come for the country.

We are inviting international journalists and content creators to apply for press accreditation for ISC26.

Norway is known for its modern, progressive sauna scene. But did you know that Norwegian badstue history goes thousands of years back?

Some speakers were announced, and we received a warm welcome to Oslo - the floating sauna capital!
