Ever wondered why people make such a fuss over the type of wood used in infrared saunas? It’s not just about looking pretty or smelling nice, though those are definite perks. The type of wood you choose for your sauna plays a big role in how it performs and how enjoyable your sauna sessions are.

Some woods hold heat better, while others resist moisture or mold. Picking the right one for your needs can seriously improve your experience and even how long your sauna lasts.

Let’s break down the best types of wood to consider when setting up or buying an infrared sauna, and what makes each one special.

Why Wood Matters in Infrared Saunas

You might think the heater does all the heavy lifting in an infrared sauna, but the wood you’re sitting on and surrounded by is just as important. Good wood helps trap heat, keeps the sauna insulated, and gives you a comfy surface to lean on during your session. You don’t want a sauna that feels flimsy or one that looks beat up after just a few months of use. That’s where wood selection comes in.

Heat Retention

The type of wood you choose impacts how the sauna holds and distributes heat. Softer woods, like cedar, don’t get super hot to the touch, making them more comfortable during long sauna sessions. Hardwoods, on the other hand, can get warmer, but they also might be better at holding onto that heat once the sauna is powered down.

Durability

Infrared saunas should be built to last, and the right wood ensures that. If you’ve got a sauna outside, you’ll need something that stands up to moisture and extreme temperature changes. Even indoors, you want wood that won’t warp, crack, or get damaged from the constant heat.

Aesthetics and Scent

Of course, it’s also about how the wood looks and feels. A well-crafted sauna made from high-quality wood can be a beautiful addition to your home. Some woods, like cedar, give off a natural, pleasant aroma, adding to that spa-like atmosphere. Others are hypoallergenic, which is perfect for anyone with sensitivities to smells or allergens.

Now, let's get into the different types of wood and see which ones are the best for infrared saunas.

Top 5 Types of Wood for Infrared Saunas

1. Cedar Wood

Cedar wood is ideal for saunas because it’s naturally resistant to mold, mildew, and decay. If you plan on using your sauna regularly, you don’t want to deal with wood that will warp or get damaged by moisture. Cedar takes care of that problem.

Another bonus? Cedar has that lovely, natural aroma. It’s not overpowering, but it adds to the relaxation experience, making your sauna feel more like a high-end spa. Plus, cedar doesn’t get super hot to the touch, which is great for longer sessions when you want to lean back and relax without feeling like you’re sitting on a stovetop.

2. Hemlock Wood

Hemlock wood is great because it’s affordable and hypoallergenic, making it perfect for people who are sensitive to certain smells or allergens. If you’re looking for a budget-friendly option that still feels high-quality, hemlock is a solid choice.

It’s also quite durable and doesn’t easily warp or crack, even with regular exposure to heat and moisture. Hemlock has a nice, clean finish that gives your sauna a modern look. If you’re someone who appreciates aesthetics as much as functionality, hemlock is a solid choice.

3. Basswood

Basswood is perfect for people with sensitive skin or allergies because it’s completely hypoallergenic. This wood won’t irritate your skin or give off strong odors, making it ideal if you have sensitivities.

In terms of looks, basswood has a light, almost creamy color, giving your sauna a soft and welcoming feel. It’s not the most durable wood on the market, but it holds up fairly well in regular sauna conditions. Just be sure to take care of it properly, especially in more humid climates.

4. Eucalyptus Wood

Eucalyptus wood is excellent for saunas because it’s tough and highly resistant to moisture, making it perfect for high-humidity environments. It’s also incredibly strong, meaning your sauna will last for years, even with frequent use.

Another perk of eucalyptus is its natural scent, which is light and refreshing, much like cedar but with its own distinct vibe. Plus, eucalyptus wood looks great, with its unique grain patterns and slightly darker tone. If you want a wood that’s both functional and beautiful, eucalyptus is a fantastic option.

5. Spruce Wood

Spruce wood is good for saunas because it’s affordable and lightweight, making it easy to work with and install. Spruce does a decent job of retaining heat without getting too hot, making it a nice option for indoor saunas.

Aesthetically, spruce has a pale, almost white finish that can brighten up any space. It’s not the most durable wood out there, but for the price, it’s a great option, especially if you’re just starting out with saunas and want something reliable but not too pricey.

Factors to Consider When Choosing Wood for Your Infrared Sauna

Okay, so now that you know the top contenders, how do you actually choose the right wood for your sauna? It’s not just about what looks the nicest or smells the best—there are a few other factors you’ll want to keep in mind before making your decision.

Durability

Let’s face it: you want your sauna to last. That means picking a wood that can stand up to the constant heating and cooling without cracking, warping, or decaying. Cedar and eucalyptus are top choices for their durability, especially in more humid environments. If your sauna is outdoors or in a space that gets a lot of moisture, you’ll want to prioritize woods that are naturally moisture-resistant.

Heat Retention and Distribution

The whole point of a sauna is to sweat, right? So, you need a wood that’s good at holding onto heat without getting too hot to the touch. Cedar is fantastic for this because it stays cooler while still trapping heat effectively. Hardwoods like eucalyptus might get a little warmer but are also great at retaining heat over longer periods.

Aesthetics and Comfort

Saunas are about relaxation, and part of that comes from being in a space that looks and feels good. Lighter woods like basswood and spruce give off a warm, welcoming vibe, while cedar and eucalyptus offer richer, more earthy tones. Think about the kind of atmosphere you want to create when you’re in your sauna and choose a wood that complements that vision.

Hypoallergenic Properties

If you or someone in your family has allergies or sensitive skin, this should be a top consideration. Woods like basswood and hemlock are ideal for those who need a hypoallergenic option. These woods don’t give off strong smells, and they’re less likely to cause skin irritation, making for a more comfortable and enjoyable sauna experience.

Conclusion

Choosing the right wood for your infrared sauna is about finding the perfect balance between aesthetics, durability, and comfort.

Take into account where your sauna will be located, how often you'll use it, and what kind of experience you're looking for. In the end, the right wood will make all the difference in getting the most out of your sauna sessions.
