The Importance of Choosing the Right Wood for Sauna Construction

Choosing the right wood for your sauna is not just about aesthetics; it's about your health, comfort, and even the longevity of your sauna. Wood plays a pivotal role in how your sauna operates, how it smells, and how it feels. So, it's not a decision to be taken lightly.

Types of Saunas

Traditional Saunas vs Infrared Saunas

Before we jump into woods, let's quickly distinguish between traditional and infrared saunas. Traditional saunas use steam to heat the room, whereas infrared saunas use, well, infrared technology to heat your body directly. This difference impacts the type of wood you should consider.

Essential Qualities in Sauna Wood

Now, let's talk about what makes a wood ideal for sauna use. There are several key qualities you should look for:

Mold Resistance

Because of the humidity, you'll want a wood that doesn't invite mold to the party.

Water Resistance

Water splashing and sweat are part of the sauna experience, so water-resistant wood is a must.

Heat Resistance

Saunas get hot (surprise!), so the wood needs to withstand high temperatures without warping or fading.

Durability

You want your sauna to stand the test of time, so choosing a durable wood is crucial.

Antimicrobial and Antifungal Properties

To keep your sauna hygienic, opt for wood with natural antimicrobial properties.

Cool to Touch

The wood should be comfortable to touch, even when the sauna is hot.

Lack of Knots and Saps

Knots can be uncomfortable to sit on, and saps can melt, causing a sticky mess.

Recommended Wood Types for Saunas

Let's break down some popular choices:

Poplar

Poplar is the VIP of sauna woods, especially for those with chemical sensitivities. It's hypoallergenic and has been the go-to choice for health clinics worldwide. Though it's on the pricier side, its benefits for detoxification and tolerance make it a top pick.

Hemlock

Hemlock is a bit of a mixed bag. It offers a traditional wood-sauna experience with a visually defined grain and a nice odor. However, it's not recommended for the chemically sensitive.

Western Red Cedar

Cedar is a classic sauna wood, known for its ability to withstand wet conditions and repel insects. However, it emits a strong odor that can be irritating to those with chemical sensitivities.

Basswood

Basswood is a budget-friendly option that tries to mimic Poplar. It's not the best choice for those with sensitivities due to its peculiar odor and potential to cause genetic damage.

Spruce / Pine

These are the most affordable but come with their own set of issues
