50

Hand‑built on Finland’s west coast by Narvi  -still the only major heater brand that designs and fabricates every component on Finnish soil—**the Narvi 50 is the most powerful wood‑burning sauna stove you can buy in North America. It’s nearly 5/8 inch‑thick steel firebox surrounds a 220‑pound stone bed, effortlessly filling up to 2,500 ft³ with rolling clouds of löyly that last for hours. Rated at ≈ 171,000 BTU/h, the 606‑pound chassis embodies Narvi’s 80‑year “zero‑compromise” philosophy on steam quality and longevity. A panoramic glass door, reversible hinge, top‑or‑rear 6‑inch flue outlet, and serviceable cast‑iron grate all speak to the same engineer‑for‑decades mindset. Backed by a 2‑year factory warranty and free U.S. freight from Sauna Marketplace, the Narvi 50 delivers life-changing Finnish heat to lodges, spas, and serious private builds alike.
