Description

Bring authentic, fire-heated sauna comfort home with the Harvia M3 BK LG FLK PKG wood-burning sauna stove package. Built around a 16.5 kW M3 heater in black, this kit pairs the heater with a matched chimney system, protective components, and stones—so you can plan a complete installation around one coordinated package for sauna rooms from 212 to 459 ft³.

The M3 heater is designed for traditional sauna bathing where the glow and feel of a real fire are part of the ritual. A glass door lets the flame add atmosphere while the heater’s steel construction and floor installation layout keep the setup straightforward for many classic sauna designs. With top and back flue connection locations and a generous 66 lb stone capacity, the heater is made to support even heat and a satisfying löyly-style steam burst when water meets hot stones.

This package is built for practical install planning, not piecemeal guesswork. Along with the M3 heater, you get a protective bedding base to help protect floors and add stability (including adjustable feet and compatibility for sloping-floor installation), plus a 3-sided protective sheath designed to reduce safety distances to combustible materials. For venting, the included chimney kit and chimney extension provide a coordinated vertical chimney solution that’s designed to be extended, with the extension specified for indoor and outdoor installation. You also receive a large floor kit and a ceiling frame to support a cleaner chimney pass-through plan, along with split-face stones in the box so you can complete the heater stone load without separate shopping.

What’s included is equally important as what it enables: consistent heat, a traditional sauna feel, and a package that helps you map out clearances and chimney routing with components that are designed to work together. If you’re building or upgrading a wood-fired sauna and want the convenience of a matched kit—heater, chimney parts, protection, and stones—this package is built to streamline that process while keeping the core experience centered on real-fire sauna bathing.

Harvia is focused on sauna and spa products and reports decades of experience in the sauna industry, with broad global distribution. The brand’s approach centers on making core sauna components—like heaters and related installation hardware—available in coordinated systems so builders and homeowners can choose a solution that matches their sauna type, room size, and installation plan.
