Which wood should you use for your sauna?

Choosing the right firewood for your sauna is crucial to having a good experience. The wood affects both the temperature, the humidity and the scent in the sauna. In this guide we go through which woods are best, what you should avoid and how to optimize your fire for maximum heat and efficiency.

 

The best woods for sauna

Björk

The most popular choice for sauna. Birch wood burns clean, provides high heat and emits a mild, comfortable scent. Its low resistant makes it sooty less than conifers.

Al 

A good alternative to björk. Alved has a smooth and slow combustion, which provides a stable heat in the sauna. It also has low resin and smells comfortable.

Aspen

Provides a pure combustion and is one of the best choices for sauna heater because it sootates minimally. Asp, however, provides slightly lower heat than björk and al.

Oak and Book

These deciduous trees have high density and provide a lot of heat. They burn for a long time but can be more difficult to light than lighter woods. Perfect if you want a prolonged glow.

 

Wood to avoid in the sauna

Conifer (spruce and pine) 

These tree species contain a lot of resin, which can cause strong smoke development and provide a sooty coating in the sauna. Sparks from the resin can also be a security risk.

Painted or impregnated wood

Can emit toxic gases in combustion and should absolutely be avoided.

Moist wood

Burns poorly, gives a lot of smoke and soothes down the sauna. Always use dry wood with a moisture content below 20 %.

 

Which wood is best in different countries?

The Nordic countries (Sweden, Norway, Finland, Denmark)

Here is björk The best option because it is easily accessible, burns clean and provides a lot of heat. Al and aspen are also good alternatives.

UK

Here is Oak and ash Popular choices. They burn for a long time and provide high heat, which is good for sauna.

Germany 

Book and oak are the most common woods for heating and work well in the sauna. They provide long burning time and high temperature.

Southern Europe (Spain, Italy, France) 

Olive and oak wood used frequently. Olive wood burns slowly and gives a unique scent, while oak provides stable and high heat.

 

How you fire effectively in the sauna

Use dry wood 

Wood should have been stored for at least 6-12 months and have a moisture content of less than 20 % for best combustion.

Light up right

Start with small knitting needles and flammable materials such as birch knots before putting on larger firewood.

Avoid to overfill The fireplace

Too much wood can suffocate the fire at once and provide an uneven heat.

Ensure good ventilation

An even air supply helps the fire to burn effectively and reduces smoke formation.

 

Summary

For the best experience recommended björk, Al or Asp in the Nordic countries, oak and ash in the UK, book and oak in Germany as well as olive wood and oak in southern Europe. These types of wood provide a clean and even combustion without excessive smoke. Avoid conifers and moist wood to avoid soot and unwanted smoke development. With the right choice of wood and fire technology you get a warmer, cleaner and more enjoyable sauna.

Heat between the sessions

After each surf session, they gathered in our Sauna Tent. It became a place to regain warmth, rest their muscles, and talk through what they had just experienced. Maybe even reflect on why they truly chase those perfect waves.

And for us, that's exactly what the sauna is all about. Not just heat – but the rhythm of recovery, performance, and community. A place to land.

That our Sauna Tent got to be part of such a journey – together with some of the world's most dedicated surfers – is something we are incredibly proud of.

Who are they?

Freddie Meadows

is Sweden's most experienced professional surfer. After ten years on the competition scene, he chose to follow his heart and start exploring Scandinavian coastlines – with the goal of finding world-class waves in our northern waters.

Nic von Rupp

Hailing from Portugal, he is known for surfing some of the biggest waves ever at Nazaré. He is a multiple championship winner, documentary filmmaker, and has twice been nominated for the World Surf League's "Big Wave Performance of the Year."

Andrew Cotton

Born in the United Kingdom, he is a pioneer of Big Wave Surfing in Europe. He has towed surfing legends into record-breaking waves, gained global recognition, and pushed the boundaries of what British surfing can be – while balancing his career with life as a parent of young children.

Sauna + surf = an obvious combination

There is something special about the contrast between cold and heat, performance and stillness. The chaos of the waves meets the calm of the tent. And for those who surf in Arctic conditions, the sauna is not a luxury – it is a necessity.

Where will the next wave happen? We don’t know. And we’re not supposed to know. But one thing is certain: our Sauna Tent will be there.

Authentic Sauna Tent Experience.

The perfect solution for those who want to enjoy a sauna anywhere, anytime, and with anyone.
