Propane Sauna Heaters

If you want fast heat-up times, powerful steam, and commercial-grade durability, a propane sauna heater is one of the best ways to heat a traditional sauna. Gas sauna heaters are especially popular for large sauna rooms, off-grid installs, and commercial sauna builds where you want reliable performance without relying on electric heating elements.

Why Choose a Propane Sauna Heater?

Propane sauna heaters deliver strong, consistent heat and are designed for sauna bathers who want an authentic high-temperature experience with plenty of steam potential. Compared to many electric sauna heaters, propane models can be a great fit when electrical capacity is limited or when a customer prefers gas heating.

• Fast heat-up times (typically 30–60 minutes depending on sauna size and conditions)
• Excellent steam production with high stone and water capacity
• No electric heating elements to replace
• Great option for large residential and commercial sauna rooms
• Built for long-term reliability and heavy use

Choosing the Right Propane Heater Size

Propane sauna heater sizing is based on your sauna room’s cubic feet, insulation quality, and how much glass or exterior wall exposure the sauna has. If you’re between sizes, it’s usually best to size up for faster heat-up times and stronger performance.

• 40,000 BTU propane sauna heater: Best for medium-to-large sauna rooms
• 80,000 BTU propane sauna heater: Best for large sauna rooms and commercial builds

Installation Requirements (Important)

Gas sauna heaters require proper venting and combustion air to operate safely. For that reason, these heaters must be installed by a licensed HVAC professional and require fresh air intake and exhaust venting to the outdoors.
