When buying a sauna, most people ask us exactly the same question.
"Does it require any special maintenance?"
And honestly? We usually say no.
This often surprises new owners, as they assume that wood left outdoors all year round will require constant impregnation, sanding, or expensive care products. Fortunately, modern garden saunas are not that demanding.
Of course, like anything made of natural wood, they need a little attention. But it's more about good habits than complicated maintenance.
Interestingly, the best-maintained saunas we've seen among our clients were not those that owners cleaned for half a day every few months. They were saunas that were cared for for a few minutes after each session.
And it is this regularity that makes the biggest difference.
Start with the simplest thing – leave the sauna open
This is a really small detail, but it can extend the life of the wood much more than many a care product.
After finishing a sauna session, most people close the door and go home. Meanwhile, high temperatures and a lot of moisture are still maintained inside.
We always advise leaving the door slightly ajar for ten, sometimes twenty minutes. If the sauna has a window, it's also worth opening it gently.
Wood really dislikes when moisture is trapped inside for long hours. However, when the interior dries out calmly, practically nothing bad happens to it.
This is one of those things that cost nothing, but really do matter.
A towel is not just a matter of hygiene
Many people spread a towel on the bench purely for hygienic reasons.
This is, of course, important, but there is a second reason.
Sweat contains salts and various substances that can leave marks on the wood over time. This is particularly visible on light benches made of thermo-aspen.
If you always sit on a towel, the wood stays clean much longer.
After the session, simply wipe the benches with a damp cloth, and that's essentially it.
Don't try to turn wood into garden furniture
This is a mistake that happens more often than you might think.
Some people buy the first available wood preservative and conclude that if it protects a terrace or fence, it will also work in a sauna.
Unfortunately, no.
The interior of a sauna operates at temperatures reaching up to 90°C. Ordinary varnishes or impregnants can emit an unpleasant odor under heat, and in extreme cases even lose their properties.
Therefore, the inside of a sauna is usually not impregnated at all. The wood should remain natural.
The situation is different on the outside. The facade should be protected from time to time with a suitable oil intended for outdoor wood. This will help it retain its color longer and better protect it from rain and UV radiation.
The stove also needs a moment of attention
This is the element easiest to forget.
The stones in the stove are not eternal.
Under continuous heating and cooling, they start to crack, and fine dust collects between them. This doesn't happen after a month or two, but it's worth checking them occasionally.
Removing the stones, cleaning the stove, and replacing the most cracked ones takes literally a few minutes.
And the difference in the stove's performance can truly be felt.
The biggest enemy of a sauna is not snow
This might be surprising.
Many people fear winter the most.
Meanwhile, a well-built sauna handles frost without problems. Thermo wood is prepared for exactly this.
A much greater threat is moisture that remains trapped inside for a long time.
That's why we so often return to the topic of ventilation. A well-dried sauna endures subsequent seasons much better than one that remains damp all the time.
Sometimes less is more
On the market, you'll find dozens of products advertised as "essential for sauna care."
The truth is, most owners never use them.
Regular ventilation, a soft brush, warm water, a towel on the bench, and a little attention are enough to keep a sauna looking great for many years.
It's a bit like a wooden table at home. You don't need to maintain it every day. You just need to take care of it.
A sauna is for relaxation, not constant maintenance
And I think that's the most important thing.
A well-made sauna should not require you to spend weekends with sandpaper and a can of impregnant.
A few simple habits after each session are completely sufficient to keep it looking great for years.
Because, after all, we buy a sauna to relax. Not to constantly wonder what else needs to be done with it.
