Emily Jul 26, 2026

Step into any traditional sauna, and you're almost guaranteed to find yourself enveloped in the warm, inviting scent of cedar. This classic wooden structure, with its rustic charm and proven benefits, has long been the gold standard for sauna enthusiasts. However, if you're considers alternatives to cedar for your sauna build, you're not alone. There are several reasons why one might look for an alternative - allergies, cost, availability, or simply the desire to try something different.

Before delving into the various cedar alternatives, let's first understand why cedar has been the preferred choice for centuries. Cedar is naturally rot-resistant and durable, it retains heat well, and its aromatic oils can contribute to a therapeutic experience. Now, let's explore some materials that could replace cedar in your sauna construction.

Primary Cedar Alternatives

When looking for a cedar alternative, you'll want to consider materials that match cedar's durability, heat retention, and aesthetic appeal. Here are two primary options:

Alaska Yellow Cedar

Despite the name, Alaska Yellow Cedar is not a true cedar but a type of cypress. It shares many of cedar's desirable qualities - similar appearance, longevity, and decay-resistance. Unlike cedar, however, it's Clear Grade Alaska Yellow Cedar that's typically used for sauna construction, ensuring no knots or defects that could otherwise pose a safety risk or detract from its aesthetic appeal.

Its natural preservatives mean it doesn't require treatment like cedar often does, making it an eco-friendly and low-maintenance option. However, it's important to note that it's a rare and costly material, potentially outpricing cedar for some.

Redwood

Redwood, particularly the heartwood, shares many of cedar's beneficial properties. It's naturally rot-resistant, has good heat retention, and offers a similar aesthetic - a warm, reddish hue with a straight grain pattern. ItsIn general, though, redwood is less durable and expensive than cedar, and it may not hold up as well in high-moisture environments or extreme temperature changes.

On the upside, redwood often requires less finishing and may not require the same periodic treatments as cedar. However, it's usually not recommended for sauna interiors due to its tendency to release "redwood dust" over time, which can be irritating to the lungs and obstructive to breathing in the steam-filled sauna environment.

Other Considerations and Alternatives

If you're looking for a compromise between cost, availability, and the benefits of cedar, consider these alternatives:

Pressure-Treated Pine

Pressure-treated pine is a cost-effective alternative, especially for sauna benches and walls. It's treated with preservatives to enhance its rot-resistance and durability. However, it may not hold up as well over time as natural, untreated woods like cedar or Alaska Yellow Cedar, and it typically requires periodic refinishing.

Additionally, the treatment process may contribute to off-gassing, which could be a concern in a tightly enclosed space like a sauna. For this reason, pressure-treated woods are usually not recommended for the sauna interior, where the heat and moisture could exacerbate off-gassing.

.domestic Lumber

If you're looking for a more sustainable and locally sourced alternative, consider using domestic hardwoods or softwoods. These might require more maintenance and may lack the natural rot-resistance of cedar, but they can still be used, especially with proper treatment and care. The key is to choose a species that offers good durability, heat resistance, and a pleasing aesthetic.

Examples include black locust, redwood (as mentioned earlier, but with reservations), and hardwoods like beech or birch. Remember, each wood has its unique properties and considerations, so do your research to ensure you're making an informed decision.

Ultimately, the best cedar alternative for your sauna will depend on your budget, local availability, and personal preference. It's always a good idea to consult with a sauna specialist or a professional builder to ensure you're choosing the right material for your needs. Whether you opt for cedar or a cedar alternative, remember that regular care and maintenance will help maximize your sauna's lifespan and your overall experience.
