How to Make the Best Wood Fired Sauna
                     How to Make the Best Wood Fired Sauna
There’s something timeless and deeply 
relaxing about stepping into a wood fired 
sauna—the earthy aroma of burning logs, the 
gentle hiss of steam on hot stones, and the 
enveloping warmth that melts away stress. 
Building your own wood fired sauna is a 
rewarding way to create a rustic wellness 
escape, but it requires careful planning to 
ensure safety, efficiency, and long-lasting 
comfort. Here are the must-haves for creating 
the perfect sauna.
Choose the Right Wood for Construction
Not all timber can withstand the high heat and 
humidity of a sauna. You need wood that won’t 
warp, crack, or release toxic resins. Western Red 
Cedar is a popular choice thanks to its pleasant 
fragrance, natural resistance to rot, and excellent 
insulating properties. Using the right wood 
ensures durability and enhances the overall 
sauna experience.
           Ensure Proper Insulation
Good insulation retains heat, reduces firewood 
consumption, and protects the structure. 
Mineral wool or rock wool are ideal insulation 
materials. Pair this with a vapour barrier—
aluminum foil works well—to reflect heat back 
inside. Sealing seams tightly prevents heat loss 
and moisture intrusion. Proper insulation helps 
your sauna heat faster, stay warmer longer, and 
maintain structural integrity.
Install a Safe and Efficient Chimney
A well-designed chimney is crucial for airflow, 
combustion, and safety. Stainless steel insulated 
chimney pipes rated for high temperatures are 
recommended. Ensure the chimney meets local 
fire codes, is installed at the correct height for 
proper draft, and safely vents smoke away. 
Consulting a professional or following detailed 
guides is essential because fire safety is non-
negotiable.
Build Comfortable Sauna Benches
Since benches are where you’ll spend most of your time, they must be sturdy, heat-safe, and 
comfortable. Use softwoods like cedar, which won’t overheat or splinter. Multi-level benches 
allow users to choose between higher heat or milder temperatures. Smooth edges, proper 
spacing, and easy-to-clean designs make your sauna more inviting and practical.
Manage Moisture and Waterproofing
Saunas are hot and humid, so proper moisture management is critical. Install drainage in the 
floor with tiles or slightly graded treated wood. Apply water-resistant sealants on exterior 
surfaces and ensure good ventilation with intake and exhaust vents to prevent mold, rot, and 
long-term damage.
Final Touch
Building a wood fired sauna combines craftsmanship with thoughtful design. With quality 
materials, safe installation, and proper moisture control, you’ll create a warm, welcoming 
retreat that lasts for years.
