Real Users Share Their Experiences: In-Depth Finnleo Sauna Reviews


Finnleo has delivered quality sauna experiences for over 100 years as a North American sauna industry leader with their extensive network of hot tub dealers – but did they maintain their roots?  There was already some question about their future when they went under the Sauna360 brand, but their future is even more uncertain now that a non-sauna public hot tub corporation (Masco) has bought out Sauna360.

For sauna kits of all types, we highly recommend you start here

Finnleo is known as a premium sauna company but they have apparently mixed in cheaply made Chinese sauna kits into the mix. It’s very difficult to know which Finnleo Saunas are made in sauna, and even their dealers (hot tub salesmen) typically have no idea.

Based on reviews, we think you can now get higher-quality European kits from companies like Auroom and SaunaLife.

Let’s dig in!

Finnleo Ownership and Alternative Brand Options in North America

Finnleo is one of the most convoluted corporate structures we’ve ever seen, and it just got even more crazy. The result of 100 years of mergers and acquisitions has dozens of companies selling the same product, many under the same ownership, under different names.

We’re not sure anyone can put this web into proper context, but its something like this: Finnleo DBA Saunatec is part of the Tylo:Helo group which is owned by Sauna360 who also owns Amerec, Kastor, Tylo, and Helo. But it doesn’t end there, as saunas are just a small part of the larger picture.

In the summer of 2023, a non-sauna public corporation named ‘Masco’ bought Sauna360. Being bought by a non-sauna company is not usually a good sign, and Finnleo seems to recognize this by hardly mentioning ‘Masco’ in their press release about being acquired by Masco . Masco is going to place Finnleo under their ‘Watkins’ brand, which consists of ‘HotSpring’, Endless Pools, Fantasy Spas, FreeFlow Spas, and Caldera Spas.

Finnleo Ownership - who owns Finnleo Sauna?

We are somewhere between confused and skeptical.

We’re not sure when the cheap Chinese sauna kits came into the mix, but surely it came along with one of these acquisitions.

Finnleo operates out of Sauna360’s Minnesota location, at least up until the acquisition.

Where are Finnleo Saunas Made?

Finnleo wants you to believe their saunas are made in Finland or the United States. Indeed, some are made in Minnesota. Unfortunately, in recent years, we’ve heard stories of a shell game. One where Finnleo reps talk about how their sauna kits are made in USA, before changing the model at the end.

You would assume all Finnleo saunas are made in the USA from the way they talk about the manufacturing process.

But the sauna that’s often sold in the end is a line that is made cheaply in China.

The parent companies made it difficult to find, but if you put Finnleo’s immediate parent company, Sauna360 into, you see the following:

We estimate the majority of Finnleo sauna kits sold in North America are coming in containers from China. Additionally, we’ve heard Finnleo dealers admit they come from China, but assist Finnleo operates the factories. According to public data, that does not appear to be the case.

Under Masco, it will be impossible to know how many containers from China contain Finnleo saunas.

Finnleo Heater Options

One thing to consider when buying a Finnleo sauna is the heater limitations.  There is typically only one option and little to no option to buy without a heater.

The heater is the heart of the sauna, and Finnleo buyers do not get to choose whether they like softer heat, higher temps (HUUM), faster heat up times, automatic steam (Virta Combi or Autodose), or Saunum air circulating heaters that blend the hot and cold spots of the sauna.

Outdoor Finnleo Sauna Kits

Finnleo offers the following outdoor saunas:

Finnleo Euro Outdoor Sauna

This is a classic ‘shed style’ sauna with a sloped ceiling. Sizes range from 4×5′ to 7×10′ with changing room. Finnlandia Euro uses economic white spruce interior walls and western red cedar exterior. Finnleo Euro models start around $20k and can easily approach $35k with delivery and heater upgrades. The Finnleo Euro can only be paired with a basic sauna heater, so there is no option for a large rock capacity heater that would provide softer heat. It’s impossible to know where the Finnleo Euro is made, from talking with Finnleo reps, internet searches, and ChatGPT.

Northstar Outdoor Sauna

Finnleo must have been tired of customers asking if they can use their indoor Northstar Saunas outside, so they slapped a roof on them and started selling these budget outdoor saunas. Northstar is the cheapest Finnleo outdoor sauna with dimensions ranging from 4×4′ to 5×7′. They use untreated spruce on the interior and exterior, in fact the construction is a single layer of spruce. The black finish will help it last, and it has a nice sized overhang so we expect it will hold up. The Euro Northstar starts around $17k and are apparently made in Minnesota.

Finnleo Metro

The Metro has a classic home look and a good layout with changing room. Unfortunately, the benches are still way too low for a true Finnish sauna experience. We also think it’s strange to use Western Red Cedar on the exterior and standard spruce in the sauna room. They could have a more durable sauna at a lower price point by using thermally modified wood like the high end Auroom and SaunaLife kits from Europe. However, the Finnleo Metro is a unique design with no competition on the market. You would have to have a sauna like this custom-built.

Finnleo Patio

Another basic outdoor model from Finnleo that looks just like a backyard shed. We’ve heard Finnleo is phasing this model out.

Finnleo Outdoor Sauna Alternatives

We strongly suggest you look at the following outdoor saunas, and chat with Sauna Marketplace representatives before buying a sauna. Most customers save thousands of dollars, months, and end up with a better performing sauna.

These premium, affordable saunas come from Europe, Canada, and USA. Most are in stock now shipping from North America.

Indoor Finnleo Sauna Kits

Finnleo Northstar Indoor Sauna Kit

4×4 indoor sauna is one of the best selling indoor sauna kits on the market, ! If limited to a 4×4′ room, this is a good choice. However, consider the Auroom Cala Mini for a major upgrade.

Northstar Issues from Finnleo Reviews, including Trumpkins Notes on Sauna appear to be fixed.

      1. Ventilation Issues: The Northstar sauna lacks proper ventilation for bathers, resulting in high levels of CO2. This can lead to bathers feeling suffocated, experiencing lightheadedness, dizziness, or other effects of hypercapnia. The sauna also struggles to expel humidity efficiently, leading to increasing humidity levels that are neither comfortable nor hygienic.
      2. Inadequate Bench and Ceiling Design: The foot bench is positioned too low, causing bathers’ feet and legs to remain in a colder zone, leading to uneven temperature distribution and discomfort. There is also a risk of mold and bacteria on the lower bench due to insufficient heat (55-65°C for 20 minutes) to eliminate these.
      3. Limited Space and Heat Recovery: The sauna’s volume is just enough for one person, making it cramped for two. It also has a limited heat cavity, leading to greater heat loss when the door is opened and a longer time for temperature recovery.
      4. Heater Proximity: The heater’s close proximity to the bathers can result in excessive direct radiant heat, which is generally not desirable in a sauna experience.
      5. Lack of Air Gap Behind Benches: The absence of a larger air gap behind the benches limits the convective heat flow, which could otherwise help in warming the bathers’ backs.





    Suggestions for Improvement:

        1. Add Proper Ventilation: It’s recommended to install a supply vent above the heater and a mechanical exhaust below the foot bench, positioned away from the heater, to improve air quality and circulation.
        2. Modify Bench Design: By removing one slat from the benches, a larger air gap can be created at the rear, enhancing convective heating and overall comfort.


      These modifications are suggested to enhance the sauna experience, addressing the issues of air quality, temperature distribution, and overall comfort.

          1. Sisu Sauna Series is a popular indoor sauna kit from Finnleo with good reviews. It’s Finnleo’s take on Almost Heaven’s Auburn sauna, or SaunaLife’s Xperience series. They are all very similar with large front windows and functional layouts. Of the 3 options, Finnleo is the most adaptable, and SaunaLife is the best value.
          2. Finnleo Hallmark series are popular free-standing saunas that are somewhat portable. These are good for renters or anyone who doesn’t want a big construction project. The Hallmark looks a little cheap for the price tag, which is over $10k but we like the corner model. The Hallmark 44 is the most popular.

        Finnleo Sauna Reviews: Still The Pinnacle of Comfort and Luxury?

        Finnleo saunas are designed to provide the ultimate in comfort, luxury, and relaxation. With options ranging from traditional Finnish saunas, infrared saunas, to combination saunas, there is a Finnleo sauna for every preference. Here are some first-hand Finnleo sauna reviews to help you make an informed decision:

            1. Traditional Finnish Saunas: “I recently installed a Finnleo traditional Finnish sauna in my home, and it’s been a game-changer for my relaxation routine. The high-quality Canadian Hemlock and Western Red Cedar materials create an exceptional sauna environment that I can’t get enough of. I highly recommend Finnleo saunas for anyone looking for an authentic sauna experience.” – John D.
            2. Infrared Saunas: “As someone who’s always on the lookout for therapeutic and detoxifying treatments, the Finnleo infrared sauna has been an absolute blessing. The direct heat from the infrared panels penetrates deep into my muscles, providing immense relief and relaxation. I couldn’t be happier with my purchase.” – Sarah M.
            3. Combination Saunas: “Finnleo’s combination sauna has been the perfect addition to my wellness routine. The flexibility to switch between traditional and infrared sauna experiences has allowed me to tailor my sessions to my specific needs and preferences. I highly recommend a Finnleo combination sauna to anyone who wants the best of both worlds.” – Michael L.
            4. Himalaya 7kW with BWT: “I have a Himalaya 7kW with the BWT. I use it all the time. It adds humidity in the room, which I prefer over totally dry heat. It also helps preserve the wood, causing less cracking, splintering, and warping when the moisture isn’t drawn out. I truly recommend it.” – Steven T.
            5. Finnleo Hallmark IS44 Combination Sauna: “I bought a Finnleo IS44 a couple of months ago. It’s the same as the Finlandia Hallmark 44 but also has infrared in addition to the traditional heater. My wife likes infrared, while I like baking out the demons with the traditional heater. I LOVE my sauna. So far, it’s been the best purchase I’ve ever made.” – Richard H.





          Finnleo BWT Technology: Experience Sauna Reinvented

          Finnleo’s proprietary BWT (Bio Water Technique) technology revolutionizes the sauna experience by providing a multi-layered sensation. This unique feature is available in several Finnleo sauna heater models, such as Piccolo, Himalaya, Vena, Laava, and Magma heaters.

          BWT allows users to enjoy a soothing, comfortable sauna environment with higher humidity levels and lower temperatures. Finnleo sauna reviews often highlight the BWT technology as a standout feature: “I love my Finnleo sauna with BWT technology. The option to switch between a gentle, more humid Flexi-Sauna experience and a traditional Hot & Dry Sauna experience has been a fantastic addition to my home spa.” – Karen P.

            Finnleo Wood Burning Sauna Heaters

            Finnleo offers a range of wood burning sauna heaters that provide the ultimate traditional sauna experience. With the soft heat, relaxing crackle of wood-fueled fire, and the lush hiss of steam, these heaters truly embody the essence of a genuine sauna.

            Designed for modern living, Finnleo wood burning heaters utilize a patented air channeling system between the outer shroud and inner firebox. This innovative system ensures efficient heating of the rocks while enhancing steam generation and air circulation within the sauna. As the fire dies down, the “Coanda” effect comes into play, redirecting the air to the side vents and allowing the stones to retain their heat longer. This results in a comfortable, long-lasting sauna session while using firewood as efficiently as possible.

            Finnleo wood burning sauna heaters feature:

                • No electricity needed, making them perfect for cabins or remote locations

                • Heat resistant paint and stainless steel outer shield for a softer heat

                • Large rock capacity for a gentle heat and steam experience

                • Patented “Coanda” air ventilation system for efficient heating and a longer steel life

                • Removable ash pan for easy maintenance

                • Interior or exterior feed options

                • Chimney outlet out the top or back

                • Optional enclosed stainless steel water tank

                • Suitable for saunas from 200 cu. ft. to 1412 cu. ft.

                • Heavy-duty steel interior for durability

                • CE safety listed (most models)

              Finnleo offers a variety of wood burning sauna heater models to suit different sauna sizes and preferences. Some models come with a small glass door, allowing you to enjoy the mesmerizing sight of the fire while you relax in the sauna. Other models feature a through-wall design with a larger glass door for added visual appeal. Some heaters are also available with a water tank to provide added humidity during your sauna session.

              Whether you’re looking for the best wood burning heater or one with added features, Finnleo has a model to meet your needs. Experience the true essence of a traditional sauna with Finnleo wood burning sauna heaters and enjoy a rejuvenating and authentic sauna session.

              Finnleo Sauna Ventilation

              Ventilation is a hot topic in sauna design. Many online sources, discussion boards, and experts claim FInnleo does not have good ventilation. They have been in the case in the past but judging by drawings and pictures on their website, Finnleo has adequate intake ventilation and in most cases they do have exhaust vents as well.

              Keep in mind, ventilation is very easy to add in sauna kits, and in some cases we prefer they did not come with the ventilation holes as sometimes we want to factor in the larger system.


              Finnleo saunas and heaters have garnered exceptional reviews from customers who have experienced the luxury, comfort, and relaxation they provide. With innovative features such as the BWT technology, a wide range of heater options, and premium materials, Finnleo continues to dominate the sauna industry. If you are considering a sauna for your home or commercial space, these Finnleo sauna reviews make it clear that Finnleo is a top choice for quality and satisfaction.
