Choosing Sauna Wood: Spruce vs Thermowood

When you're buying a sauna, the choice of wood is a fundamental decision. Wood doesn't only shape the look of your sauna — it affects durability, maintenance and even the sauna experience itself. In the sauna market, two woods are widely used: Spruce and Thermowood. In this article, we look at the characteristics of each to help you make a more informed choice.

Spruce

Spruce is a wood commonly used in the construction of Finnish saunas. Native to the northern regions of Europe and Asia, it's known for its light colour and tight grain, which give saunas a clean and elegant appearance.

Advantages of Spruce

• Heat Resistance: Spruce has a notable ability to withstand high temperatures, making it well suited to the atmosphere of a sauna.

• Durability: While not as durable as Thermowood, Spruce is still a long-lasting option that can serve many years if properly maintained.

• Appearance: Spruce has a natural sheen and tight grain that gives a visually attractive aesthetic.

Thermowood

Thermowood, also known as heat-treated wood, has gone through a thermal treatment process. This process improves the wood's durability and its resistance to decay and insects, making it an excellent option for saunas.

Advantages of Thermowood

• Exceptional Durability: Thermowood is extremely durable and resistant to decay and insects — ideal for a sauna built to last.

• Heat Resistance: Like Spruce, Thermowood also resists heat well, making it perfect for the sauna environment.

• Maintenance: Thanks to its thermal treatment, Thermowood requires less maintenance than Spruce.

So, which to choose?

The choice between Spruce and Thermowood mainly comes down to your needs and personal preferences. If you value the natural aesthetic and the warm, welcoming atmosphere Spruce delivers, it may be the right choice for you. If you prefer a low-maintenance sauna that stands the test of time, Thermowood is an excellent option to consider.

Ultimately, both Spruce and Thermowood offer excellent qualities for your sauna. The key is to choose a wood that meets your specific needs and matches the style and aesthetic you want.
