Why Are Saunas Made Of Wood?

So why are saunas made of wood? Interestingly enough, the term ‘sauna’ is derived from a Finnish word that means “room of wood.” Wooden structures are preferred over anything else for several reasons:

  • Heat Insulation

Heat Insulation Wooden materials, though, remain comfortable to the touch even in a warm environment because it’s an excellent insulator.

It also keeps the heat inside the structure much more efficiently.

  • Aesthetics

The neatly aligned rows of planks used for building a sauna just gives a lot more aesthetic appeal than any other material. It imparts a relaxing atmosphere that makes you feel closer to the natural environment.

Summary: Wooden constructs are popular because they’re natural heat insulators, hygienic, heat-resistant, and easy to maintain.

What’s a Sauna?

Saunas are individual rooms or enclosed spaces that are meant to generate and trap heat.

People stay in these rooms for short periods to refresh their body, but recent studies have been attributing the use of saunas with other benefits, such as:

Traditional saunas typically use hot steam as a heat medium. But recently, more and more are making the switch to the electric infrared sauna because they produce a gentler heat while imparting the same, if not better, advantages.

Summary: Saunas are heat-retaining rooms that individuals use for recreational or health purposes.

Which Sauna Wood Type is Most Often Used?


hemlock, cedar, basswood, and poplar are often used woods for saunas. Pine & Eucalyptus can be used. Cedar possesses a rich aroma and is often used to build a sauna. Poplar is natural wood and is best for sensitive people.

Also, it depends on the location and the purpose. Most public units feature scentless materials so they can suit a more extensive range of users. Personal units can widely vary because owners will often choose a material that fits the aesthetic of their homes.

Summary: Most public sauna and bathhouses use odorless materials to account for hypoallergenic or smell-sensitive individuals.

Is Hemlock Wood Toxic?

It is probably one of the most misunderstood plants in the world. The common belief that is most commonly heard that is just totally false. It is the Hemlock tree that is toxic. Why is the Hemlock Wood Poisonous? The Hemlock tree is in the hemlock genus which is one of the most poisonous plant families in the world. Even though it is not that poisonous, the tree has such a strong and distinctive smell that it makes people want to touch it. In time, they will also notice that if they come into contact with the sap of the tree, it can cause irritation on their skin and be harmful. And as they continue to deal with the sap on their skin, it may lead to problems with their lungs, and digestive system or cause them to cough up a lot of phlegm.

Luckily, the tree is not that poisonous so it’s safe to eat if you’re not allergic to it. However, this tree can cause problems for people if they have kidney problems or high blood pressure. But when it comes having an irritated stomach, can cause a lot of discomforts. This wood can also be very poisonous if you are exposed to it in large amounts. However, in small amounts, people don’t really know the real damage it can cause to their bodies. More Facts About Hemlock Wood. It can be found growing in many places around the world. However, it is the forests of Appalachia and New England that it is most often found. In other places, it can be found in areas like the Mediterranean and South America as well. If you find this and other trees growing around you, don’t take it. Instead, move it to somewhere else where you can appreciate its beauty and view it from a distance.

Is Basswood Rot Resistant?

Basswood rot, or Conkle’s disease, is an epidemic fungus that feeds on fresh rot and spreads to living oak. It is responsible for the millions of holes that we see all over the East. As with the bark-eating fungi that grow on Douglas Fir trees, and other new, and old rot diseases, the fungus eventually destroys the tissue that makes up a tree’s vascular system, causing limbs to break and die.

Because of the tree’s extremely shallow roots, little or no secondary growth can occur if basswood rot becomes established, which makes tree removal necessary. One thing that makes basswood rot so devastating is that it has a much higher survival rate in basswood than in its “hardier” host tree species. Unlike some of the other “new rot” diseases, the roots of a basswood tree have little chance to become infected until the disease.

Eucalyptus vs Cedar Sauna

Of the two, the cream-of-the-crop are the trees and the sauna experience of the ancient indigenous Mesoamericans. Instead of the heat and steam, these trees and their clusters of smooth bark create and detect the natural cooling and warming cycles of the earth, and in a less brain-rattling effect than even winter’s cold snap, allow one to enjoy a sweltering sauna experience. Today, a sauna is most often a hulking steel-encased cube of wood, steel, and stone. Many of these saunas are found in Chinese steam baths or on a beach in Turkey.

Interestingly, the steel saunas were constructed in the late 1930s in the United States when they were away for the educated class to escape the heat of a big city and enjoy a pleasant solitary experience. As such, they tend or a country farmhouse that doesn’t feel so hot. Most have the brand name Saunas Uta (or similar) imprinted on the side, indicating they were designed in Finland. But the sauna is a centuries-old Nordic creation and a smaller sauna at the turn of the century at Columbia University would have been no more elaborate than a hand-cranked searing oven.

Is Cedar Sauna Toxic?

Scientists have managed to isolate a part of the fungus associated with UTI symptoms. They found that the endosymbiont—that is, the fungi that live on the walls of the bladder—produces a metabolite that is dangerous to the human body. In addition, scientists discovered that the fungus is attached to the cells of the host bladder. This indicates that these tiny bladders might be involved in the production of harmful substances.

Scientists used this information to work out how the amount of fungus in the bladder might vary with the severity of the infection. The findings have been published in the latest issue of the Journal of Urology. The article is titled “Diversity of Endosymbionts of Human Bladder Microbiota and Their Role in Bacterial Urinary Infections.

What Factors Are Considered When Picking Sauna Wood?

  • Scent

You might opt to go for a scentless unit if you’re highly sensitive to smells. It’s also a wise choice to test if you have an adverse reaction to the wood beforehand since aromatic woods occasionally cause skin irritation.

  • Lifespan

Not every material can last in the moisture and heat-heavy environment of a sauna without getting damaged.


So if you can afford it, choose one that’s highly durable to save you the potential costs of repairs and replacements.

Be prepared and learn how to treat sauna wood the proper way before you make your decision.

  • Availability

Some woods are rarer than some. Always check if what you want is available in your area. For example, you might find abundance in hemlock wood for sale if you live in America, but options for Eucalyptus units are limited.

Summary: Aside from the obvious looks factor, you also need to look out for the scent, lifespan, and availability when choosing a material.

Is Pine OK to Use in a Sauna?

Nuts are not recommended for direct sun exposure. If your dog happens to be under the sun, the fat contained in the nuts can cause sunburn. The fat and oil can also lead to skin irritation, possibly leading to skin irritation in dogs. In contrast, pine tree extracts are excellent natural moisturizers. If your dog’s skin is dry, you might try soaking your dog in a tub of water infused with pine tree extract.

If your dog has allergies, be aware that pine pollen is extremely irritating to the skin. Many dogs will react to pine trees without even having been in the yard or have symptoms that don’t immediately clear up. Pine tree extracts should be avoided in places where pets are banned from consuming tree sap, such as saunas and pools, or a residence where the pets are likely to ingest pine tree sap, such as your home. If you find that your pet’s symptoms are severe, consult with your veterinarian.
