Description

Bring classic wood-fired sauna heat to your build with the Harvia M3 SS MD FLK PKG — a 16.5 kW wood-burning sauna stove package designed for sauna rooms 212–459 ft³. This complete kit pairs the Harvia M3 heater with a stainless steel chimney system, protective components, a dedicated floor solution, and sauna stones, so you can plan your install around a matched set of core essentials.

At the center of the package is the Harvia M3 wood-burning heater, built for floor installation and engineered to promote even heat through efficient air circulation. The M3 features an elegant graphite-black finish, a stainless steel air-flow spoiler, and a glass door that lets firelight complement the sauna atmosphere. With 16.5 kW of power output and recommended sauna-room coverage from 212 to 459 ft³, it’s a strong fit for compact-to-mid-size sauna rooms where you want the feel and ritual of real flame-fired heat.

This package is designed to simplify planning by bundling key components commonly needed around a wood stove installation. It includes protective bedding to help protect floors and provide an adjustable, stable base. A 3-sided protective sheath is included to help reduce safety distances to combustible materials. For venting, the kit provides a stainless steel chimney kit with insulation plus a matching chimney extension designed to help manage movement from temperature changes and suitable for indoor or outdoor placement where required by the installation layout. You also receive a thermally enhanced spruce floor kit (Medium) that creates a stable walking surface with weather resistance and warp resistance, along with a thermally enhanced spruce ceiling frame that accommodates the chimney kit and space for insulation. Finally, the package includes olivine diabase split-face sauna stones to support proper heat retention and steam when water is ladled over the heated stone bed.

What’s included is clearly defined so you can coordinate your build: the heater set (stove, door, ash box, manual), the protective base and safety sheath, chimney components and install hardware for the chimney lead-through and rain sealing parts, the floor kit and ceiling frame, and the sauna stones. If you’re building a traditional wood-burning sauna experience and want a coordinated set of core components in one package, this configuration is built to get you there with fewer separate part decisions.

Harvia focuses on sauna heating and sauna-room equipment with an emphasis on durable materials, functional design, and installation-ready component systems. The M-series wood-burning heater design is intended for sauna users who want a traditional bathing experience powered by wood heat, supported by compatible chimney and protection components that are purpose-built for sauna environments.
