The Harvia Linear 16 Black is a 17.9kW wood-burning sauna stove for rooms from 212 to 565 cubic feet, in Harvia's Linear Series - a design lineage described by Harvia as combining timeless style with a strong structure. The sculptural graphite black profile with cast-iron glass door creates a visual statement in the sauna room while providing efficient, quick-heating wood-fired heat. The fire chamber and combustion air channels are engineered for rapid warm-up and a cleaner burn. The cast-iron glass door is reversible - the opening direction can be changed during installation. The durable steel structure with replaceable internals is built for long service life. Sauna stones (80 lbs, 2 boxes of AC3020, 10-15 cm) are required and sold separately. Delivery is by scheduled pallet freight.
Linear Series - timeless sculptural design with strong structure
Harvia positions the Linear Series at the intersection of aesthetic ambition and engineering durability. The stove's profile is described as sculptural and timeless - a clean, architectural form that complements both traditional log sauna rooms and contemporary sauna interiors without the industrial look of a utilitarian stove. The graphite black finish adds visual depth. The strong structure is not cosmetic - the Linear 16 is built with durable steel and replaceable internal components, meaning the fire grate and combustion chamber parts can be replaced individually as they wear without replacing the entire stove. This is a meaningful long-term cost advantage: the visible aesthetic remains intact while worn internals are renewed over years of regular use.
Combustion air channels - quick warm-up and cleaner burn
The fire chamber and combustion air channels of the Linear 16 are specifically engineered for two outcomes: the sauna warms quickly, and the burning is cleaner. The combustion air channel design directs airflow through the fire chamber to improve combustion completeness - more fully burned wood gases produce less soot, less unburned particulate in the flue gases, and a more efficient burn from each firewood load. The quick warm-up characteristic is practically important: a wood-burning sauna that reaches temperature faster reduces the total wood consumption per session and gets the sauna ready in less elapsed time from lighting. The Linear 16 meets CE marking requirements for wood-burning stove safety and emissions performance.
Reversible cast-iron glass door and installation flexibility
The cast-iron glass door can be reversed to open left or right - set during installation to suit the sauna room layout and the preferred access direction from the bench position. This flexibility means the door swing can be optimised for any room configuration without ordering a specific handed model. The cast-iron frame provides the thermal durability required for the sustained high temperatures of a 17.9kW fire. A model-specific protective sheath (for Harvia 16/Linear 16) is available as an accessory (sold separately) and reduces the safety distances to combustible materials when installed, giving additional flexibility in bench placement within the 212-565 cu ft room range.

Why the Harvia Linear 16 stands out
Timeless sculptural design - graphite black
The Linear Series stove is positioned as a design object as much as a heating appliance - a sculptural form in graphite black that Harvia describes as adding timeless style to the sauna. For sauna rooms where the stove is a visual focal point rather than an appliance to hide, the Linear 16's clean architectural profile suits contemporary sauna design without the rustic aesthetic of the Legend Series or the industrial appearance of purely utilitarian stoves.
Replaceable internals - long service life
The durable steel structure with replaceable internals is a differentiating feature of the Linear Series. Fire grates and combustion chamber components experience the most wear in a wood-burning stove. The Linear 16's replaceable internal design means worn components can be replaced individually - preserving the stove's exterior appearance and structural integrity over years of regular use without requiring a full stove replacement. This is a long-term value advantage over stoves without individually replaceable internals.
Combustion air channels - quicker warm-up
The purpose-designed fire chamber and combustion air channels produce both faster sauna warm-up and a cleaner burn compared to simpler fire chamber designs. Faster warm-up means less elapsed time from lighting to bathing temperature and less firewood consumed per session. A cleaner burn means less soot accumulation in the flue and on the glass door - reducing chimney maintenance frequency and keeping the cast-iron glass door cleaner between sessions.
Reversible cast-iron glass door
The cast-iron glass door can be reversed to open in either direction - set at installation. This flexibility means the door swing can be optimised for access from the bench, the firewood storage position, or the room entry point without ordering a specific configuration. The cast-iron frame provides sustained durability at the high temperatures produced by a 17.9kW fire. The fire visible through the glass creates the traditional wood-burning sauna atmosphere throughout the session.
565 cu ft upper range - more room than M3 or Legend 150
The Linear 16's 565 cu ft upper room volume is 106 cu ft more than the M3's and Legend 150's 459 cu ft ceiling. For medium rooms between 460 and 565 cu ft where the M3 and Legend 150 are insufficient, the Linear 16 is the correctly sized interior-feed wood stove in the BathingBrands lineup - covering the gap between the smaller stoves and the 706+ cu ft range of the PRO 20 and Legend 240 SL. The 17.9kW output for the 212-565 cu ft range also makes it a well-matched stove for rooms at the mid-to-upper end of this range.
Optional protective sheath - installation flexibility
The Harvia protective sheath designed specifically for the Harvia 16/Linear 16 (sold separately) reduces the safety distances to combustible side and back surfaces when installed around the stove. In sauna rooms where the standard 11.8" side clearance cannot be achieved with the desired bench layout, adding the protective sheath opens up additional placement options. This is a practical accessory for sauna builders working with tight room dimensions in the 212-565 cu ft range.

Linear 16 vs M3 vs Legend 150 - same overlap zone, different designs
Linear 16 vs M3 vs Legend 150 - choosing in the 212-459 cu ft overlap range
Three BathingBrands stoves cover the 212-459 cu ft range: M3 WKM3, Legend 150 WK150LD, and Linear 16 WK160C. Above 459 cu ft up to 565 cu ft, only the Linear 16 applies. Within the overlap zone, the choice is design and stone load: M3 is the compact best-seller at 15.4"W with 66 lbs of stones - the practical, space-saving choice. Legend 150 is the large stone mass option at 264 lbs - maximum thermal retention, cast-iron glass door, two-stage combustion air grate. Linear 16 is the sculptural timeless design option at 80 lbs of stones - reversible door, replaceable internals, clean graphite black profile that suits contemporary sauna rooms where the M3's utilitarian look and the Legend's rustic character are both less appropriate. All three deliver the authentic wood-burning experience. The Linear 16 is also the only interior-feed stove in this lineup that covers rooms up to 565 cu ft.
