Safety Rules for Wood-Fired Saunas
                     Safety Rules for Wood-Fired Saunas
Wood fired saunas deliver a timeless, 
authentic experience. The natural heat, 
crackling fire, and scent of cedar create 
a setting that’s hard to match. But with 
that rustic charm comes responsibility. 
Operating a wood-fired sauna safely is 
key to protecting your investment, your 
property, and most importantly—your 
health. Here’s what you need to know 
before you strike that first match.
Choose the Right Location
Before anything else, pick a safe spot 
for your sauna. A flat, fire-safe surface 
is essential. Keep it away from trees, 
overhanging branches, sheds, or 
anything flammable. Make sure there’s 
enough ventilation around the unit to 
avoid smoke build up. 
Install a Heat Shield
Your wood stove should be installed with 
proper clearance between it and the sauna 
walls. Northern Lights’ barrel saunas use 
high-quality cedar, which resists heat 
naturally, but adding a stainless-steel heat 
shield behind the stove gives an extra layer of 
protection. 
Use Proper Firewood
Hardwoods like oak, birch, and maple burn hot 
and clean—ideal for sauna use. Avoid treated or 
painted wood, as these release toxic fumes when 
burned. Always keep firewood dry and stored 
away from the sauna to reduce the risk of sparks 
igniting your supply. 
Never Leave the Fire Unattended 
Even if you’re just stepping away for a quick cool-
down, always assign someone to keep an eye on 
the fire. Unattended flames can flare up fast. 
Wood fired or burning saunas build heat 
gradually, so it’s easy to monitor the temperature 
and adjust as needed. 
Monitor the Temperature
A proper sauna experience starts with the right heat. 
Traditional sauna temperatures should stay between 
150°F and 190°F—don’t go beyond that range. 
Installing a reliable thermometer inside your sauna 
helps you keep an eye on the temperature and avoid 
overheating, which can damage the wood and cause 
issues like dizziness or dehydration.
Ventilation Is Key
Good airflow isn’t just a comfort feature—it’s essential for safety. Every 
Northern Lights barrel sauna includes both an intake and exhaust vent to keep 
fresh air moving and prevent carbon monoxide buildup. Make sure these vents 
remain open and unobstructed at all times.
Keep a Fire Extinguisher Nearby
It might seem like a small detail, but having a fire extinguisher close to your 
sauna is a smart move. Mount it in a spot that’s easily accessible but away from 
direct heat or moisture. It’s a simple precaution that can make all the difference in 
an emergency.
Hydrate Before and After
Saunas naturally cause you to sweat—and lose fluids. Drink plenty of water 
before and after your session to stay hydrated. Skip the alcohol; it affects your 
body’s ability to regulate heat and can lead to dehydration or poor decision-making 
while inside the sauna.
