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.
