What’s the Best Wood for a Sauna? A Complete Guide
Stepping into a sauna is a soothing experience, enhanced by the right natural wood. But many overlook a key question: What’s the best wood for a sauna? Choosing wisely matters—saunas face extreme heat (up to 200°F), fluctuating humidity, and constant moisture, so the wrong wood warps, cracks, or emits odors over time.
This guide breaks down critical factors, top wood options, and key tips to help you pick durable, safe wood for your sauna.
Why Sauna Wood Selection Matters
Sauna wood must meet essential criteria: heat resistance (withstand extreme temps), moisture resistance (avoid rot/mold), safety (non-toxic, splinter-free), durability (last 10+ years), and aesthetics. Softwoods are ideal—hardwoods (oak, maple) conduct heat too quickly and warp easily, while softwoods (cedar, hemlock) are lightweight, insulating, and moisture-resistant.
The Top 6 Best Woods for Saunas
Below are the most popular, high-performing woods, ranked by performance and versatility.
1. Western Red Cedar (The Gold Standard)

2. Canadian Hemlock (Budget-Friendly Premium)
