Choosing between a wood-fired and electric heater is one of the most important decisions when designing a sauna. Both can deliver an exceptional experience, but they differ in convenience, installation requirements, and atmosphere.
At The Sauna Standard, we help customers navigate these choices. Here's what to consider.
Wood-Fired Saunas: The Traditional Experience
For those seeking the most traditional sauna experience, we recommend a wood-fired heater.

Wood-fired saunas have been central to Finnish and other sauna cultures for generations. There's something special about building a fire, hearing the wood crackle, and enjoying the distinctive aromas of burning wood.
Wood-fired heaters can produce exceptionally high temperatures, although a properly designed electric sauna can reach equally impressive temperatures.
One major advantage is the ability to operate completely off-grid. Wood-fired saunas don't require an electrical connection, making them particularly appealing for remote properties, cabins, and outdoor installations. Even the lighting in our wood-fired rental saunas is powered by rechargeable battery packs.
Wood-fired heaters that draw combustion air from inside the sauna also promote natural airflow. As the fire burns, it draws air into the stove and exhausts combustion gases through the chimney, creating a natural draft. With properly designed fresh-air intakes and ventilation, this can provide effective air exchange without mechanical exhaust ventilation.
Wood-fired installations require proper chimney design, fire safety clearances, and ventilation. They also require more hands-on attention, including building and maintaining a fire, managing firewood and ashes, and allowing time for the sauna to heat up.
For many enthusiasts, though, that ritual is an integral part of the appeal.
Electric Saunas: Convenience and Control
Electric heaters offer a different set of advantages, with convenience at the top of the list.
Rather than building a fire, you can turn on your sauna with the push of a button. Many modern electric heaters offer programmable controls and Wi-Fi connectivity, allowing you to schedule heating sessions in advance.
But convenience doesn't mean electric saunas are necessarily simpler to design.
Proper heater sizing is critical. The heater must be matched to the sauna's volume, insulation, and materials. Large glass surfaces (such as doors and windows) can increase heating power requirements.
Electrical infrastructure is another consideration. Depending on the heater's capacity, an electric sauna may require a dedicated 240-volt circuit and sufficient available electrical capacity.
Ventilation also requires careful planning. Unlike wood-fired heaters that draw combustion air from the sauna, electric heaters don't create a combustion-driven draft through a chimney. Properly positioned intake and exhaust vents—and, in many designs, mechanical ventilation—are essential for maintaining fresh air and comfortable circulation.
When designed correctly, an electric sauna can deliver an exceptional experience with minimal effort.

So, Which Is Better?
Whichever sauna is available to you :)
During my travels in Finland, I experienced some truly exceptional saunas, both wood-fired and electric. Some of my favorites were heated by electricity, while others were heated by wood. I also experienced traditional smoke saunas, which deserve an article of their own.

What stood out the most wasn't necessarily the type of heater, but the quality of the löyly (the steam and heat experienced when water is poured over the stones), the thoughtful design, and the people sharing the sauna.
Great sauna design matters more than the choice of fuel alone. Heater sizing, ventilation, bench placement, insulation, and overall room geometry all contribute to the quality of the experience.
Ultimately, the best choice comes down to personal preference, your property, and how you plan to use your sauna.
