Sauna Wood Stove Chimney Kit

DESCRIPTION

The Harvia chimney is an easy-to-install stylish chimney solution. The steel chimney withstands extensive changes in temperature and has mainly been designed for use with woodburning stoves, smaller fireplaces, and iron stoves in detached sauna buildings.

The standard delivery of the steel chimney includes a steel chimney and a utility box with a rain cap, a rubber rain flange and an installation set for rain flange, a stainless steel lead-through flange for the ceiling, a lead-through insulation and protector. The package also includes a non-isolated smoke pipe. Supplementary parts are available as accessories for this stainless steel chimney. Thanks to an ingenious mechanism, the supplementary parts are wound together and the smoke pipes are also equipped with slots to lock them together. This prevents movement caused by temperature changes. Indoors, the chimney can be installed up to a height of 9′ 8″ without support and outdoors the corresponding self-supported installation height is 6′ 6″.

The rated maximum temperature of combus­tion gases for a furnace connected to a steel chimney is 600 ºC. The external diameter of the steel chimney is 8.66″ and the diameter of the smoke pipe is 4.53″. The safety distance to inflammable materials is 3.94″. The Harvia steel chimney has a CE-marking, so the product complies with all international fire- and operational safety requirements. The steel chimney is sootfire proof.

CUSTOMER REVIEWS

What Owners Are Saying

No reviews yet for this product.

★★★★★

A nightly ritual we never skip.

The cedar smell hits the moment you open the door. Heat is even, the door seals tight, and the build feels like it will last decades. Worth every dollar.

★★★★★

Genuinely flawless craftsmanship.

Pre-drilled holes lined up perfectly, hardware was stainless and substantial, and the heater was already wired. Two of us assembled it in a weekend.

★★★★★

Centerpiece of our backyard.

Guests at our rental mention the sauna in nearly every review. The barrel shape sheds snow beautifully and the interior light is so warm.

DAILY PRACTICE

The power of heat.

A consistent sauna practice compounds quietly into a measurable health investment. Regular heat exposure is linked to gains in cardiovascular conditioning, muscle recovery, and resilience to stress — benefits that build session after session.

30 min

A single sauna session can elevate heart rate to levels comparable to moderate exercise, supporting cardiovascular conditioning.

2–3×

Regular sauna use of two to three sessions per week is associated with measurable improvements in cardiovascular health in long-term studies.

20 min

Twenty minutes of heat helps relax muscles, accelerate recovery, and lower perceived stress after a long day.

ANATOMY OF THE SAUNA

Every surface, every fastener — chosen on purpose.

Grade A Knotty Western Red Cedar, an external wood-fired stove as standard (Harvia electric available as an upgrade), and marine-grade stainless steel hardware. Each component is selected for how it behaves under heat and steam, then handcrafted and fully assembled in Northern Minnesota.

OUR WORK

Real projects.

From private gardens to commercial recovery suites, every Cedar Sense build is shaped to its setting. A look at saunas we’ve delivered for owners across North America.

Frequently Asked Questions

Cedar Sense helps you design and build the sauna setup that actually fits your space, budget, and lifestyle. Here are answers to the questions we get asked the most.

What types of saunas does Cedar Sense offer?

We offer outdoor barrel saunas, indoor saunas, and custom-built sauna rooms, as well as complimentary amenities like cold plunges, outdoor showers, wood-fired hot tubs, and cedar outdoor furniture. Our goal is to help you create a complete fire-and-ice experience at home or at your cabin.

Yes. We created a FREE Custom Sauna Build Guide and a simple design flow to help you plan location, layout, bench height, heating system, and ventilation before you start building.

Yes. We ship saunas, cold plunges, outdoor showers, and most cedar products across the continental United States. Shipping options and costs depend on the product and your location, which you’ll see at checkout or by requesting a quote.

For many areas in the upper Midwest, we can either provide installation/assembly options or connect you with trusted partners. In other regions, most of our saunas arrive as kits designed for a handy homeowner or local contractor. Contact us to discuss installation options in your area.

Wood-fired stoves give you a traditional, off-grid feel with a softer, “campfire” style heat and crackling ambiance. Electric stoves are cleaner, easier to control, and often available with Wi-Fi and timers. Your ideal choice usually comes down to power availability, local codes, and the sauna experience you prefer.

Lead times vary by model and season, but most saunas ship within a few weeks to a couple of months. Custom builds and special configurations may take a bit longer. We’ll provide an estimated timeline before you finalize your order.

Absolutely. We carry sauna buckets and ladles, thermometers, sand timers, essential oils, sauna sprays, flooring, clocks, and more. We also offer cold tubs, outdoor showers, and cedar furniture that pair perfectly with your sauna setup so you can create a complete backyard retreat.

Yes. The guide is 100% free. You’ll just enter your name and email so we can send you the PDF and follow up with helpful tips about planning your build. No obligation and no pressure to purchase.
