Best Wood for Sauna Walls: A Guide to Choosing the Right Material

If you’re planning to build a sauna, one of the most important decisions you’ll make is choosing the best wood for your sauna walls. Not only does the wood contribute to the overall aesthetic of your sauna, but it also affects the quality and durability of your sauna experience. With so many wood options available, it can be overwhelming to decide the best wood for sauna walls in your home.

Key Takeaways

  • Softwood, such as pine and cedar, is the most commonly used wood for saunas due to its natural resistance to moisture and heat.
  • Cedar and redwood contain natural oils that provide a pleasant aroma and therapeutic benefits during your sauna experience.
  • When choosing the best wood for your sauna walls, consider your specific needs and preferences, as each wood has its own unique properties, benefits, and drawbacks.

Understanding Sauna Wood Fundamentals

When it comes to building a sauna, the type of wood you choose for the walls is essential. Not only does it affect the aesthetics and sensory experience, but it also influences the sauna’s performance and durability.

Softwoods vs Hardwoods

The two main categories of wood are softwood and hardwood. Softwood comes from coniferous trees like pine, cedar, and spruce, while hardwood comes from deciduous trees like oak, birch, and maple. Softwood is the most commonly used wood for saunas, primarily due to its natural resistance to moisture and heat. Softwoods are also more affordable and easier to work with than hardwoods.

Heat and Moisture Considerations

The wood you choose for your sauna walls needs to be heat and moisture-resistant. Temperatures in traditional saunas can reach up to 200°F, and if the wood is sensitive to these kinds of temperatures, it will discolor or degrade quickly. Softwoods like cedar and hemlock are ideal for saunas because they have a low thermal conductivity, which means they don’t transfer heat as quickly as other woods. They also have natural oils and resins that make them resistant to moisture, decay, and insects.

Aesthetic and Sensory Attributes

Aside from its performance, the wood you choose also affects the sauna’s aesthetics and sensory experience. Cedar is a popular choice for its pleasant, soothing aroma when heated, enhancing the sauna experience. Hemlock is another popular choice for its light color and straight grain, giving the sauna a clean, modern look. Spruce and pine are also options, but they have a more rustic appearance and are less durable than cedar or hemlock.

In summary, when choosing the best wood for sauna walls, consider softwoods like cedar and hemlock due to their natural resistance to moisture and heat. Also, keep in mind the aesthetic and sensory attributes of the wood and how they can enhance the overall sauna experience.

Top Wood Choices for Sauna Walls

Not only does the wood need to be heat-resistant, but it should also be durable, hypoallergenic, and aesthetically pleasing. In this section, we’ll take a look at some of the top wood choices for sauna walls.

Cedar: The Traditional Favorite

Cedar is a softwood that is naturally resistant to decay and insects. It is the most popular choice for sauna wood and has been used for centuries. Cedar has a pleasant aroma that enhances the sauna experience, and it is a good insulator, which helps to keep the sauna warm. Western red cedar is a popular choice due to its durability and beautiful color.

Hemlock: Durable and Allergen-Free

Canadian hemlock is a hardwood that is durable and allergen-free, making it an excellent choice for sauna walls. It has a light color and a straight grain, which makes it easy to work with. Hemlock is also a good insulator, which helps to keep the sauna warm.

Spruce: The Nordic Choice

Norway spruce is a softwood that is commonly used in Nordic saunas. It has a light color and a straight grain, which makes it easy to work with. Spruce is also a good insulator, which helps to keep the sauna warm. It is important to note that spruce can be prone to splintering, so it may not be the best choice for high-traffic areas.

Aspen: Hypoallergenic and Smooth

Common aspen is a popular choice for sauna interiors and exteriors. It has a light tone, smooth texture, and it does not secrete resin. Aspen is hypoallergenic, making it an excellent choice for people with allergies. It is also a good insulator, which helps to keep the sauna warm.

Eucalyptus: Exotic with a Unique Aroma

Eucalyptus is an exotic hardwood that is not commonly used in saunas but can add a unique aroma to your sauna experience. It is a durable wood that is resistant to decay and insects. Eucalyptus has a reddish-brown color and a straight grain, which makes it easy to work with. It is important to note that eucalyptus can be expensive and may not be readily available in all areas.

Choosing the right type of wood for your sauna walls is important for both the functionality and aesthetics of your sauna. Consider your personal preferences, budget, and the availability of different types of wood in your area before making a final decision.

Special Considerations for Different Sauna Types

Traditional Saunas: High Heat and Steam

When it comes to traditional saunas, the wood used for the walls should be able to withstand high temperatures and humidity levels. Cedar is a popular choice for its natural resistance to moisture and decay, as well as its insulating properties that help maintain consistent temperatures. Other woods that can be used for traditional saunas include aspen, hemlock, and spruce. However, spruce is not considered a high-quality wood and is often used for certain parts of the sauna to reduce costs.

Infrared Saunas: Low Heat and Direct Warmth

Infrared saunas operate at lower temperatures than traditional saunas and use infrared radiation to heat the body directly, rather than heating the air. Therefore, the wood used for infrared saunas does not need to be as water-resistant or moisture-resistant as the wood used for traditional saunas. Cedar is still a popular choice for its pleasant aroma when heated and its insulating properties, but other woods like basswood and poplar can also be used.

Outdoor Saunas: Weather Resistance and Durability

Outdoor saunas require wood that is weather-resistant and durable. Cedar is a great choice for outdoor saunas because it is naturally resistant to decay and insects, and can withstand extreme temperatures and humidity levels. Other woods that can be used for outdoor saunas include redwood, teak, and cypress. These woods are also resistant to decay and insects and can withstand harsh weather conditions.

When choosing the wood for your sauna walls, it is important to consider the type of sauna you have and its specific requirements. Traditional saunas require wood that can withstand high temperatures and humidity levels, while infrared saunas require wood that is not as water-resistant or moisture-resistant. Outdoor saunas require wood that is weather-resistant and durable. Cedar is a popular choice for all types of saunas, but other woods like aspen, hemlock, spruce, basswood, poplar, redwood, teak, and cypress can also be used depending on the sauna type and location.

Practical Aspects of Sauna Wood Selection

When it comes to selecting the best wood for your sauna walls, there are several practical aspects to consider. Here are some factors to keep in mind:

Cost-Effectiveness and Availability

The cost of sauna wood can vary greatly depending on the type of wood and its availability. Cedar wood is a popular choice for saunas due to its natural resistance to decay and insects, as well as its pleasant aroma. However, cedar is also one of the most expensive woods for saunas. If you are on a budget, you may want to consider other woods such as spruce, hemlock, or aspen.

Resistance to Bacteria and Fungi

Another important factor to consider is the wood’s resistance to bacteria and fungi. Saunas are humid environments, which can promote the growth of bacteria and fungi. Therefore, it is important to choose a wood that has natural antifungal and antibacterial properties. Cedar wood is naturally resistant to bacteria and fungi, making it a popular choice for saunas. Other woods that are resistant to bacteria and fungi include hemlock, spruce, and aspen.

Maintenance and Longevity

The maintenance and longevity of sauna wood is also an important consideration. Sauna wood should be easy to maintain and should last for many years. Cedar wood is known for its durability and longevity, making it a good choice for saunas. However, cedar wood also requires regular maintenance to keep it looking its best. Other woods that are easy to maintain and have a long lifespan include hemlock, spruce, and aspen.

In summary, when selecting the best wood for your sauna walls, you should consider cost-effectiveness, availability, resistance to bacteria and fungi, and maintenance and longevity. Cedar wood is a popular choice due to its natural resistance to decay and insects, pleasant aroma, and antifungal and antibacterial properties. However, if you are on a budget, you may want to consider other woods such as spruce, hemlock, or aspen.

Building Your Sauna: DIY Tips and Tricks

Choosing the Right Wood

When it comes to building a sauna, choosing the right wood is crucial. You want to use a type of wood that can withstand high temperatures and humidity without warping or cracking. Cedar, hemlock, and aspen are popular choices for sauna walls because they are durable and have a pleasant aroma. Cedar, in particular, is known for its natural resistance to decay and insects, making it a great choice for sauna construction.

When selecting your wood, make sure it is resin-free. Resin can cause an unpleasant odor when heated and can also cause skin irritation. Look for wood that is clear of knots and other imperfections, as these can weaken the wood and cause it to crack over time.

Sauna Construction Techniques

When constructing your sauna, there are a few techniques you can use to ensure it is built to last. One important technique is to leave a small gap between the sauna walls and the bench supports. This allows for air circulation and helps prevent moisture buildup, which can lead to mold and mildew.

Another important technique is to use stainless steel screws and nails. These are more resistant to corrosion than other types of metal and will hold up better in the high humidity of a sauna.

Finishing and Sealing Wood

Once your sauna is constructed, you’ll want to finish and seal the wood to protect it from moisture and make it easier to clean. There are several options for finishing your sauna, including natural oils, water-based sealers, and polyurethane coatings.

Whichever option you choose, make sure it is safe for use in saunas and does not contain harmful chemicals. Apply the finish according to the manufacturer’s instructions and allow it to dry completely before using your sauna.

In conclusion, building a sauna can be a fun and rewarding DIY project, but it requires careful consideration when it comes to choosing the right wood, construction techniques, and finishing and sealing methods. By following these tips and tricks, you can create a sauna that is both functional and beautiful.

Softwoods like cedar and hemlock have a warm and inviting feel, while hardwoods like aspen and birch have a smoother texture. You can also add a wooden bench or backrest to make your sauna more comfortable.

Health Benefits of Sauna Woods

Different types of sauna woods offer different health benefits. Cedar is a popular choice for saunas because it is naturally resistant to decay and insects, and has a pleasant aroma that enhances the sauna experience. Hemlock is another popular choice because it is hypoallergenic and has a smooth texture that is comfortable to sit on. Nordic spruce is known for its detoxifying properties, while aspen is believed to help with respiratory issues.

In conclusion, enhancing your sauna experience is all about paying attention to the details. By incorporating aromatherapy, focusing on comfort and touch, and exploring the health benefits of different sauna woods, you can create a sauna that is both relaxing and rejuvenating.
