Harvia M3 SS Pkg Wood-Burning Sauna Stove Package, 16.5kW
The Harvia M3 SS Sauna Stove Package is a complete ready-to-install package for small to medium sauna rooms from 212 to 459 cubic feet. Everything needed to get a traditional wood-fired sauna running is included in a single order: the M3 16.5kW wood-burning stove, WL100 protective floor bedding, WL450 protective sheath, WHP1500M stainless steel chimney kit, chimney extension, and 66 lbs of AC3020 sauna stones (2 boxes, 10-15 cm). The only item required separately is the 6" North American flue adapter for converting the M3's standard 115mm (4.5") European flue outlet. This package eliminates the compatibility research and multi-vendor coordination of assembling a stove system piece by piece - everything ships together from an authorized Harvia dealer.
The Harvia M3 - a classic best-seller for small and medium saunas
Harvia describes the M3 as having a classic design that is suitable for small saunas, turning a sauna bath into a pleasurable experience with a touch of traditional sauna atmosphere. The M3 has been in continuous production for decades and is one of the most widely installed wood-burning sauna stoves in the market - tens of thousands of saunas have been built around it. The graphite black steel body with stainless steel air-flow spoiler is compact: 15.35"W x 16.93"D x 27.95"H with a net weight of 99.2 lbs. The glass door on the front face allows the warm glow of the fire to complement the sauna atmosphere throughout the session. Adjustable legs and an ash box are standard. The 16.5kW output and 66-lb stone capacity deliver even heat and efficient air circulation for consistent, enjoyable sauna bathing from 212 to 459 cu ft.
What the SS package includes - stove, sheath, bedding, chimney, and stones
The SS designation stands for stainless steel and identifies the complete package configuration. The WL450 protective sheath is included - this is the model-specific sheath for the M1, M2, M3, and M3 SL. When installed, it reduces the safety clearances from the standard 10" at the sides and 12" at front and back down to approximately 3" on all sides from combustible materials, giving much greater flexibility for bench placement within the sauna room. The WL100 protective floor bedding is aluminium-zinc coated steel, painted black, for installation on tile or hardwood floors. The WHP1500M stainless steel chimney kit and the chimney extension complete the vertical chimney run. The 66 lbs of AC3020 stones (2 boxes) fill the stone compartment to the required minimum. A licensed or certified chimney professional is recommended for all flue installations.
115mm flue - one required item not in the package
The only item not included in the M3 SS Package that is required for a complete North American installation is the 6" flue adapter. All Harvia wood-burning sauna stoves use the European standard 115mm (4.5") flue outlet. North American chimney installations use 6" (155mm) piping, so the Harvia WZ115155 adapter is required to connect the stove to a standard North American chimney run. This adapter is sold separately at BathingBrands. Everything else - stove, sheath, floor bedding, chimney kit, extension, and stones - is in the package. Delivery is by scheduled pallet freight - a freight appointment is required before shipping.

⚠️ 6" North American flue adapter (Harvia WZ115155) required - not included in this package. This is the only item required for a complete North American installation that is not in the SS Package. The adapter converts the M3's 115mm (4.5") European flue outlet to the 6" (155mm) standard used in North American chimney installations. It must be purchased separately. Everything else - stove, WL450 sheath, WL100 floor bedding, WHP1500M chimney kit, chimney extension, and 66 lbs of AC3020 stones - is included. This package ships by scheduled pallet freight - a delivery appointment is required. A licensed chimney professional is recommended for all flue installations.
ℹ️ M3 SS Package vs M3 stove only - what the package adds. The M3 stove sold individually (BathingBrands SKU: WKM3M) includes only the stove, glass door, ash box, adjustable legs, and installation manual. The M3 SS Package (this listing, SKU: M3-PKG-SS) adds the WL450 protective sheath (reduces clearances to approx. 3" all sides), WL100 floor bedding (for tile and hardwood floor installations), WHP1500M stainless steel chimney kit, chimney extension, and 66 lbs of AC3020 stones (2 boxes). The package is the right choice for a first-time installation where sourcing all components separately would require multiple orders. The stove-only listing is the right choice for replacement or for buyers who already own a compatible chimney system and accessories.

Why the Harvia M3 SS Package stands out
Complete package - one order, ready to install
The M3 SS Package is a fully pre-specified bundle: stove, floor bedding, protective sheath, chimney kit, chimney extension, and stones are all included and sourced from Harvia as compatible components. For a first-time sauna installation, this eliminates the compatibility research and multi-vendor coordination of assembling the components separately. Every item in the package is a genuine Harvia product with a known fit to the M3 stove. The only additional purchase required for a complete North American installation is the 6" flue adapter - everything else ships together.
WL450 sheath included - 3" clearances from the start
The WL450 protective sheath is the model-specific sheath for the M1, M2, M3, and M3 SL stoves. In the standard M3 stove-only configuration, safety clearances to combustible materials are 10" at the sides and 12" at front and back - meaningful distances in a small sauna room. With the WL450 installed, those clearances reduce to approximately 3" on all sides. The SS Package includes the WL450 as a standard component, so the reduced clearances are available from installation day one without a separate purchase. For small sauna rooms in the 212-459 cu ft range where bench placement near the stove is important, the WL450 directly increases usable space.
The Harvia M3 - decades of proven performance
The M3 is one of the most widely installed wood-burning sauna stoves in production history - tens of thousands of saunas have been built around it. The graphite black steel body with stainless steel air-flow spoiler, glass door, adjustable legs, and ash box is a platform that has been refined and maintained by Harvia for decades. Spare parts are available. The installation and operation manual is comprehensive. The platform is supported by Harvia's authorized dealer network. For a buyer choosing a wood-burning stove for a permanent sauna installation, the M3's longevity in the market is direct evidence of its reliability.
Stainless steel chimney kit - CE-marked, soot-fire proof
The WHP1500M stainless steel chimney kit included in the SS Package is a Harvia-manufactured chimney component with CE marking, confirming it meets European fire and operational safety requirements. The stainless steel construction is soot-fire proof and rated for both indoor and outdoor installation. The chimney extension provides additional height flexibility for routing the flue above the roof line. Together the chimney kit and extension provide a complete vertical chimney run from the 115mm stove outlet to the outside - sized for the M3's output and designed as a compatible system for direct installation.
66 lbs of stones included - 2 boxes AC3020
The SS Package includes the full minimum stone requirement for the M3: 66 lbs of AC3020 stones (2 boxes, 10-15 cm). The stones fill the stone compartment to the level required for safe operation - operating the M3 without the correct stone load is not permitted by the installation manual and voids the warranty. AC3020 stones are Harvia's olivine diabase stones sized and shaped specifically for the M3's 10-15 cm stone cavity. Having the stones included in the package means the stove can be loaded and fired as soon as the installation is complete, without a separate delivery wait. An additional box of stones beyond the 2 included is recommended to allow selection of the best-fitting stones for the compartment.
Classic M Series design - compact and efficient for small saunas
At 15.35"W x 16.93"D x 27.95"H and 99.2 lbs, the M3 is one of the most compact full-output wood-burning sauna stoves in the Harvia lineup. Harvia notes it is the smallest and most narrow wood-burning model in the line, and one of the smallest available anywhere - while still delivering 16.5kW for rooms up to 459 cu ft. The stainless steel air-flow spoiler improves combustion efficiency. The even heat and efficient air circulation are the product of decades of Harvia fire chamber and combustion air channel design. The glass door adds the warm glow of the fire to the sauna atmosphere throughout the session. CE and EAC certified. Made in Finland. We are an authorized Harvia dealer.

M3 SS Package vs M3 stove only vs M3 SL - M Series selection guide
M3 SS Package vs M3 stove only vs M3 SL - choosing the right M Series configuration
Three M Series options are relevant for buyers considering the M3 SS Package. M3 stove only (WKM3M): just the stove, glass door, ash box, and legs - no sheath, bedding, chimney, or stones. Right choice for a replacement installation where a compatible chimney is already in place and the accessories are already owned. M3 SS Package M3-PKG-SS (this listing): complete package with WL450 sheath, WL100 floor bedding, WHP1500M chimney kit, chimney extension, and 66 lbs stones included. Right choice for a new installation where sourcing all components individually would require multiple orders and compatibility research. M3 SL (WKM3SLM): exterior-feed configuration where the fire chamber extends through the sauna wall - wood is loaded from an adjacent room or outdoors, and the glass door faces the adjacent room for a fireplace view. Same 16.5kW output and room range as the standard M3. Right choice when exterior wood loading or a dual-room fireplace experience is the installation goal. All three share the same M3 stove platform, CE and EAC certifications, and Harvia's 2-year warranty.

Warranty
2-year limited warranty (consumer use)
The Harvia M3 wood-burning sauna stove is covered by Harvia's 2-year limited warranty from the date of purchase for consumer use. The warranty covers defects in manufacturing and materials under normal use conditions.

Individual package accessories (WL100, WL450, WHP1500M, chimney extension) are covered under their own Harvia product warranties. A licensed or certified chimney professional is recommended for all flue installation and regular chimney sweep maintenance. Proof of purchase from an authorized Harvia dealer is required for warranty claims. We are an authorized Harvia dealer.
