What is the best wood for a sauna?
The short answer: there is no single best wood, only the right wood for your setup. Western red cedar is the premium pick for outdoor cabins because its natural oils resist moisture, insects, and decay, and it stays cool to the touch. Hemlock gives you similar strength and a near odorless, hypoallergenic surface at a lower price, which suits indoor and infrared builds. Basswood and aspen are the go to woods for anyone with sensitive skin or allergies, since both are virtually free of resins and aromatic oils and leave no splinters. Thermowood, which is heat treated aspen or spruce, adds stability and moisture resistance for outdoor use. Match the wood to your location, your budget, and any skin sensitivities, and you will be happy with the result for years.
How the selector works
The tool weighs your three answers and points you to the wood that fits best. Location decides how much the wood has to fight moisture and weather. Your priority, price, aroma, allergies, or durability, sets the tie breaker. And your sauna type matters because infrared cabins pair well with low odor woods like basswood and hemlock, while traditional and barrel saunas often use cedar or thermowood. Cedar heartwood is rated resistant to very resistant to decay by the USDA Forest Products Laboratory, which is why it holds up outdoors. See the Forest Products Laboratory technical sheet on western redcedar for the details.
Sauna wood types compared
| Wood | Best for | Aroma | Allergy friendly | Relative cost |
|---|---|---|---|---|
| Western red cedar | Outdoor and premium builds | Strong, pleasant | Moderate | High |
| Hemlock | Budget indoor and infrared builds | Very light | High | Low to mid |
| Basswood | Sensitive skin, benches, infrared | None | Very high | Mid |
| Aspen and thermo aspen | Family saunas, allergy free surfaces | None | Very high | Low to mid |
| Thermowood, heat treated | Outdoor stability and durability | Light, toasty | High | Mid to high |
Costs are relative guides, not our catalog prices. Wood is one factor among heater type, size, and features.
Frequently asked questions
What is the most durable wood for an outdoor sauna?
Western red cedar and thermowood hold up best outdoors. Cedar has natural oils that resist moisture and decay, while thermowood is heat treated to improve stability and moisture resistance. Both suit a backyard cabin that faces weather year round.
Which sauna wood is best for allergies or sensitive skin?
Basswood and aspen are the safest picks. Both are virtually free of resins, tannins, and aromatic oils, so they rarely trigger skin or respiratory sensitivity, and they stay smooth without splinters. Hemlock is also close to odorless if you find cedar too strong.
Is cedar worth the extra cost?
For an outdoor sauna or if you love the aroma, cedar is often worth it because it lasts and needs little maintenance. For an indoor or infrared sauna where weather is not a factor, hemlock or basswood give you a great surface for less.
