Sauna maintenance in cold season
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.
Hot tub maintenance: water, wood and stove
A well-maintained hot tub offers not only relaxation, but also safety and long-term comfort. Whether you have a wood-fired or electric model, proper maintenance of water, structure and stove is essential.
1. Water – clean, safe, balanced
- Change the water completely every 1–2 weeks
- Use filtration systems and check them periodically
- Test and balance pH and alkalinity:
- pH: 7.2 – 7.8
- Alkalinity: 80–120 ppm
You can use active oxygen tablets or natural products for light disinfection.
2. Wood – protected and well maintained
- Clean surfaces with a soft cloth and warm water
- Apply special oils once every 6–12 months
- Use a thermal insulation cover for protection
3. Stove – efficiency and safety
For wood stoves:
- Empty the ash after each use
- Clean the glass door and check the seal
- Inspect the chimney for deposits
For electric stoves:
- Check the control panel and outlets
- Make sure the control unit is protected from moisture
4. General hygiene – monthly maintenance
- Clean the inside of the tub with a soft brush
- Wash headrests and accessories
- Ventilate the hot tub well after use
- Avoid lotions and body oils
