Square Feature Functionality

The Sauna Square by Thermory is the perfect solution to a sauna that can also function as a yoga space or your own personal quiet retreat.

You’ve been looking for that and congrats! You found it!

With more than enough room for 6 bathers to sit comfortably, the Sauna Square is one of the roomiest “barrel” saunas on the market, giving you opportunity to host your friends for a sauna session, or fully lay out on the top benches and take full advantage of optimal heat… and with all of the seating on elevated benches, everyone can be in that sweet spot!

The Square design is a perfect blend of a cabin and a barrel, giving you the added space that comes with vertical walls, at a price in the barrel range. The ability to sit right against the wall with more than ample headroom is a game changer when it comes to this sauna.

At 6’4” interior height (almost 4 feet above the bench!), the Sauna Square provides a spacious interior that feels HUGE, while maintaining a small footprint.

Life is better when you’re square.

With two options available, there’s no doubt that this will work in your space, whether it be indoors or outdoors.

Model #40 includes a rear panoramic window, while the #41 is a solid rear wall, making it perfect for placement against a wall, or added privacy if needed.

Both saunas come with the same great upper benches, an expansive 8mm tempered glass front, an included duckboard flooring kit, and a front porch that is great for cooling off during your sauna session. They also come with an included rain jacket and super easy to follow instructions that make this kit an easy build for 2 in about 8 hours. Minimal tools needed!

The BEST Durability On The Market

The thermal modification process used on all Thermory Saunas is one where the materials undergo intense heat and steam in a giant vacuum giving the wood a superior resistance to rot. Proven to hold up to more than 25 years of abuse, the thermal modification of lumber is still not even fully tested, as their test subjects are still going strong!

The use of this process on Northern European soft woods has given us a product that is supremely smooth, while also giving us the durability of pressure treated lumber with NO chemicals!

A Promise To The Planet

In addition to Thermory’s commitment to use no chemical processing, they also responsibly source their lumber from expertly managed forestry programs in Northern Europe, ensuring that there is NO harm to woodlands or wetlands around the globe.

A Promise To Our Customers

Sauna Marketplace still has the first Sauna Square in North America set up for virtual tours (it makes a great office too!).  We offer free consultations and are with you for every step of the build.  Book a planning session today.
