Cozy Heat O Sauna Stove Description

A unique wood-burning sauna stove hand-made in Estonia, where sauna is a way of life. Wood-fired sauna stoves are best for mild and long-lasting heat, designed for pouring water over hot stones to create the perfect amount of steam. Enjoy a satisfying traditional sauna experience with the Cozy Heat O sauna heater!

  • 12kW – for saunas from 210 to 423 cu.ft.
  • 18kW – for saunas from 317 to 635 cu.ft.

COZY has taken the ancient craft of building a sauna to a higher level. The part of a wood-burning heater that must be the strongest, the flame cutter, is made of sturdy, 5mm-thick stainless steel making COZY heaters extremely durable.

This unique wood-fired sauna stove is hand-made in Estonia, where sauna bathing is ingrained in the national culture.

The Cozy Heat O wood-burning sauna stoves are perfect for mild and long-lasting heat, designed for pouring water over hot stones to create intense and luxurious steam for a more gratifying sauna experience. At the heart of the Cozy Heat O is its innovative circular rim design, which not only enhances the heater’s aesthetic appeal, but also ensures efficient heat distribution throughout your sauna space.

Sauna Stones

Split Faced Stones

The Cozy traditional sauna stones are 10-15 cm in size and are for use with Cozy sauna heaters and stoves.

The shape and size of each stone is unique, so we recommend purchasing an additional box of sauna stones for the best variety of size for fit, form, and performance. 44 lbs.

Premium Rounded Stones

sauna with hot rocks

Olivine diabase is a tough rock that is able to withstand the high temperatures in a sauna without cracking or breaking easily. This is important because cracked stones can trap moisture and eventually crumble, reducing their effectiveness and potentially damaging the heater. Olivine diabase has a high density, which means it absorbs and stores heat well. This allows the stones to stay hot for a longer period, providing consistent heat throughout your sauna session.

When water is poured on the hot stones, it creates soft, gentle steam. This is because the olivine diabase heats evenly and releases the heat gradually, avoiding the harsh flash of steam you might get with some other materials.

Overall, olivine diabase offers a good balance of durability, heat retention, and steam production, making it a smart choice for sauna stones.

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.

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.
