Key Factors When Choosing Sauna Wood

Before diving into specific wood types, it's important to understand the qualities that make a wood suitable for a high-heat, high-moisture environment. Here are the crucial factors to keep in mind:

• Heat Resistance: Sauna wood must withstand high temperatures without warping, cracking, or becoming too hot to touch. Softwoods are generally preferred.
• Moisture Resistance: Wood should resist rot, mold, and mildew. Tight grain and natural oils help.
• Durability: Choose woods that last for years and resist decay.
• Aroma: Cedar provides a classic scent, while Aspen is hypoallergenic and low scent.
• Resin and Knots: Too much resin can melt; avoid woods with excessive knots.
• Appearance: Light and modern or rich and rustic—choose your style.
• Cost: Prices vary widely, so match wood choice to your budget.
