The Kuuma BLUFLAME is a Gasification wood-burning sauna stove designed to burn wood cleanly, efficiently, and safely to provide the ultimate sauna experience.

It is an ideal option for sauna businesses and owners that care about efficiency (have to purchase wood) and operate in environments where you want the least amount of wood smoke possible (typically urban areas or if you have problematic neighbors) or you want to make wood burning easy and fun.    

Our Legacy Kuuma wood-burning sauna stove is known for its legendary build quality, efficiency, and clean burn.  Our new Kuuma BLUFLAME is roughly 25% more efficient and cleaner burning than our Legacy Kuuma. Compare this to the competition, and you’re talking about twice as efficient with the ability to customize the sauna experience to the type of microclimate you desire.  Made in Tower, MN, using American steel, local labor, and high-quality materials! #burnwoodbetter 


Nearly a century after manufacturing our first Finnish-American sauna stove Lamppa Manufacturing looks to revolutionize the sauna stove market with the ability to create your own ultimate sauna experience using a safe, clean, and efficient gasification wood burning sauna stove.  

Take the hassle out of wood burning by making it simple and fun.  Ask someone who owns or has already tried a Lamppa Kuuma sauna stove, and you will see why they are recognized for their quality design and providing an unmatched sauna experience.
