Learn how to keep your sauna and hot tub in perfect condition with practical tips and step-by-step guides for easy and efficient maintenance.
1. Check the stove before the season
Whether you use an electric or wood-fired stove, make sure it is cleaned and in perfect working condition.
Completely clean the remaining ash
Check the chimney or flue for deposits
Inspect the volcanic stones – cracked ones must be replaced
Recommendation: use only dry, hard wood (e.g. birch, beech) for efficient and clean burning.
2. Ventilate the sauna after each use
Leave the door and any windows open for 15–30 minutes
Do not cover the ventilation grilles
3. Protect the exterior wood
Apply 1–2 coats of special exterior oil (e.g. Tikkurila, Njord Protect)
Avoid snow accumulation on the sauna roof
Periodically clean exposed surfaces with a damp cloth
4. Check insulation and sealing
The door closure must be sealed – you can adjust the hinges
Apply heat-resistant silicone in corners with leaks
Check the roof and walls for signs of moisture
5. Heat correctly, not suddenly
Electric stove: set the temperature gradually
Wood stove: light the fire 30–45 minutes before
Do not force the stove with too much wood at once
Conclusion: Proper maintenance means better thermal comfort and increased lifespan of your sauna.
