Types of Wood Used in Sauna Construction

The woods used in sauna construction are selected from special tree types that are resistant to harsh conditions like high heat and humidity, and are naturally safe for health. Choosing the right type of wood both extends the sauna’s lifespan and maximizes user comfort. In this article, we will discuss the most commonly preferred types of wood for sauna construction and the reasons behind their selection.

The Importance of Using Wood in Saunas

Wood is the primary material that defines both the aesthetics and functionality of a sauna. By absorbing heat and balancing the environment, wood maintains a touchable surface temperature, making it much healthier than synthetic materials. Additionally, it creates a pleasant aroma and natural atmosphere.

Preferred Wood Types

1. Cedar

With its antibacterial properties, pleasant scent, and low resin content, cedar is one of the most preferred woods for sauna construction. It shows high resistance to heat and humidity, and its reddish color provides a decorative appearance.

2. Spruce

Spruce is widely used due to its affordability and durability. It has a light and simple appearance and is especially common in Finnish-style saunas.

3. Abachi (Ayous)

Originating from West Africa, this wood is often preferred for seating and leaning areas due to its low thermal conductivity. Even when heated, it does not burn the skin, providing comfort advantages.

4. Hemlock

This Canadian wood type is resin-free and features straight grain, making it an aesthetic and healthy choice. Its calm color tones are suitable for modern sauna designs.

5. Pine

Pine is chosen for some low-budget projects because it is economical. However, due to its high resin content, its usage is limited. Resin-free processed varieties can be suitable for saunas.

Considerations When Choosing Wood

Resin content should be low (for health and cleanliness)
It must be resistant to heat and humidity
It should resist cracking and warping
Surface temperature should remain comfortable
It should emit a pleasant and natural scent

Selecting the right type of wood for sauna construction extends its service life and enhances the user experience. Trees such as cedar, spruce, abachi, and hemlock are ideal choices in sauna projects due to their durability and natural properties. With the appropriate wood selection according to your project’s purpose and budget, you can enjoy the sauna experience for many years.
