Softwood, like cedar, is popular because it remains cool and doesn’t absorb too much heat. Some of the best types of wood for saunas include western red cedar, redwood, western hemlock, Nordic spruce, common aspen, Alaskan yellow cedar, Douglas fir, pine (if thermally treated), eucalyptus, and magnolia.

1️⃣ Types of Saunas: Traditional vs. Infrared

Before delving into the different wood options, it’s essential to understand the differences between traditional and infrared saunas. Traditional saunas have been used for centuries and are known for their high heat and steam. They create a hot and humid environment by heating rocks or panels and radiating heat throughout the sauna.

The choice of sauna wood is influenced by the type of sauna you have. Traditional saunas require wood that withstand high heat, moisture, and humidity. The wood should be heat-resistant to warping, water-resistant to withstand steam and sweat, and mold-resistant to prevent the growth of fungi. Cedar is a popular choice for traditional saunas because it remains cool to the touch and has natural antimicrobial properties.

Infrared saunas, on the other hand, do not require wood with the same level of heat and moisture resistance. While durability is still essential, the focus shifts to woods resistant to humidity and mold. This opens up the options to include woods like Nordic spruce, which offers a light and airy aesthetic, or western hemlock, which has a mild scent and is known for its stability.

When choosing the suitable wood for your sauna, it’s essential to consider the specific needs and preferences of your sauna experience. By understanding the differences between traditional and infrared saunas, you can choose the best wood type. Whether you opt for the classic appeal of western red cedar or explore other suitable wood types like redwood or Douglas fir, selecting the suitable wood will enhance your sauna room’s aesthetics and functionality.

2️⃣ Factors to Consider When Choosing Sauna Wood

When selecting sauna wood, it is crucial to consider several key factors to ensure it performs well in the environment. The type of sauna you have, whether traditional or infrared, will dictate specific requirements for the wood. In general, you’ll want wood that is heat resistant, water resistant, mold resistant, durable and has antimicrobial and antifungal properties.

In traditional saunas, where high heat, moisture, and humidity are present, choosing the wood that can withstand these conditions is essential. Look for wood species with natural heat resistance, such as cedar or redwood. These woods handle high temperatures well and have the added benefit of remaining cool to the touch, ensuring a comfortable sauna experience.

For infrared saunas, which emphasize heat penetration rather than high humidity, the focus shifts towards selecting wood less prone to mold growth. While water resistance is still essential, woods like western hemlock or Nordic spruce can be suitable options. These woods may not have the same level of heat resistance as cedar or redwood, but they provide good durability and low maintenance in an infrared sauna setting.

Wood Type Heat Resistance Water Resistance Mold Resistance Durability Antimicrobial Properties Antifungal Properties
Western Red Cedar High High High High Yes Yes
Redwood High Moderate High High Yes Yes
Western Hemlock Moderate Moderate Moderate High Yes Yes
Nordic Spruce Moderate Moderate Moderate High Yes Yes

Other factors to consider when selecting sauna wood include ease of maintenance, availability, and aesthetic appeal. Some woods, like cedar or redwood, have natural oils that make them resistant to insects and decay, reducing the need for frequent maintenance. Certain wood types may also be more readily available in your region, making them a practical choice.
