What Type of Wood To Use In Your Sauna

Let’s BUild Your Dream Sauna.

So you’re thinking of building your own sauna? Or maybe, you’re ordering from a dealer and trying to figure out what the best sauna wood is for your incoming sauna. Regardless of motive, you’re in the right place. Aside from the size of your sauna, and the stove you choose, the sauna wood is one of the most important pieces of your sauna.

Choosing the longest lasting sauna wood is one of the most important decisions sauna owners make. Historically, many folks assumed that cedar was the only wood used in sauna. Actually, while Western Red Cedar, specifically, is one of the most sought after types of sauna woods on the market, it’s not the most popular wood used in Saunas.

Nordic Spruce is the most popular sauna wood in the world. In fact, it’s estimated that Nordic Spruce is used in over 90% of saunas worldwide. Our Nordic Spruce comes directly from Finland, with small, tight living knots that emit a subtle sauna smell while inside the room.

What Wood Is Most Commonly Used In Saunas?

When building your own sauna, the wood type you choose will have the largest impact on the overall cost of the sauna room. And not just any wood material should be used to build a sauna, it must have specific characteristics that make it suitable for the high heat and humidity found inside a sauna room. There are 6 most common types of wood used to build saunas.

  1. Nordic White Spruce
  2. Clear Western Red Cedar
  3. Canadian Hemlock
  4. Knotty Cedar
  5. Black Taika
  6. Abachi
  7. Heat Treated Alder

Nordic White Spruce

Nordic White Spruce is actually one of the most popular woods used in sauna, due to it’s affordability and long lasting durability. There are many advantages to building saunas with Nordic White Spruce.

When it comes to building a Sauna, the wood used on the interior is one of the most important factors in the overall quality, determining how long the Sauna room will last. When built correctly, using the right materials for construction and with proper maintenance, a Sauna can often out-live it’s owner. Nordic White Spruce is designed to last for decades inside a sauna room, for even the most serious of sauna users.

Nordic White Spruce is the most commonly used type of wood to build Saunas. In fact, it is estimated that Nordic White Spruce is used in more than 90% of Saunas world-wide!

The Nordic White Spruce we use in our saunas is imported from Finland, specifically north of 60 degrees latitude. The growing conditions in Finland’s far north produce a result that is superior for use inside a sauna. Here, near the Arctic Circle, the unique growing conditions create an unusual softwood that is not porous in nature, which is excellent for use inside the sauna.

For those seeking a Sauna built using Nordic White Spruce, our Northstar Sauna line is the single most popular choice. Of course, we do full custom indoor and outdoor saunas built using any of the recommended building materials our clients select. If you would prefer not to buy a pre-fabricated sauna kit, we also offer fully customized pre-cut sauna in a box saunas.

Western Red Cedar

Why is cedar used for saunas? Due to it’s price, cedar is not actually the most popular type of wood used in sauna rooms. Western Red Cedar is one of the most versatile wood types for sauna, because of it’s ability to withstand moisture and resist rot over long periods of time. As a fun fact, many of my friends Grandparents who built their saunas out of cedar back in the 50’s and 60’s, are still using the exact same saunas today. Cedar lasts an incredibly long time in a sauna.

Cedar Kits for Sauna

Because of the fact that sauna dealers are so few and far between, buying a kit to build your own sauna or choosing a prefab unit is often one of the best ways to get a sauna. Interested in a cedar sauna kit? We offer kits that you can install in nearly any space, in just a few hours. All of our Sauna kits come complete with everything you need to start using your Sauna right away, without buying the entire thing piece by piece, a process that can take months.

Cedar vs Hemlock in Sauna Rooms

While Hemlock and Cedar are two of the most common wood types used in sauna, cedar is the superior choice. Cedar wood, specifically Western Red Cedar, outperforms Hemlock in a sauna when it comes to durability and longevity. Hemlock is more affordable than Cedar wood for saunas, however, it is not generally the preferred choice due to the length of time cedar will last.

Canadian Hemlock

To the untrained eye, spotting the difference in Canadian Hemlock and Clear Western Red Cedar is actually very difficult. In fact, many sauna users will tell you that the only difference between hemlock and cedar is actually in color. Hemlock wood in sauna is a popular choice for good reason, price.

Most of the sauna units or kits you’ll find online are constructed using hemlock wood, specifically Canadian Hemlock.

What lasts longer in sauna, hemlock or cedar?

Cedar wood, when maintained properly, is one of the longest lasting sauna wood types available to consumers, and will generally last longer than Hemlock. Both types of sauna wood are excellent building materials due to their moisture resistant properties, and ability to properly dry after use.

Why are saunas built using wood, won’t it get moldy?

Avoiding mold in your sauna is actually very easy. There are a couple things you can do to prevent mold in your sauna, ensuring you have a safe sauna unit for years to come. Despite the fact that wood is one of the first things to mold in nature, saunas rarely experience mold issues, largely due to the wood types used in building them.

Here’s how to avoid mold in sauna

  1. Ensure your sauna is completely level, so water cannot pool on the floor in any way
  2. Prop your sauna door open after every use ensuring healthy airflow throughout the unit
  3. Check sauna benches regularly and replace as needed
  4. Do not leave wet buckets, towels, or other items sitting in your sauna

Avoiding mold in a sauna is actually very easy, most sauna owners will never run into this problem. For saunas inside your home, letting your air conditioning or furnace maintain the homes humidity and simply propping the door open will take care of the rest!
