Let’s talk about the nitty-gritty of barrel sauna engineering! Our barrel saunas are engineered to last, with precision milling to ensure the ideal seal for superior heat retention. And while most barrel saunas tend to trap water, promoting rot, our models are designed to withstand years of love in any climate.

Log rounds stacked together

Made out of natural wood that’s thermally modified using a 100% natural process, you can breathe deep knowing you’re taking in the cozy aroma of Nordic Spruce without any harsh chemicals or toxins.
