sauna maintenance

Saunas are not only luxurious additions to our homes or favorite spas but also beneficial for health and relaxation. Owning a sauna, however, comes with a responsibility: ensuring it remains in top condition. Proper maintenance not only extends the life of your sauna but also ensures a safe and enjoyable experience every time. In this article, we'll delve deep into the essentials of sauna maintenance, offering expert tips that will help keep your sauna running smoothly.

1. Regular Cleaning is Key

  • After Each Use: Wipe down the benches and walls with a clean, dry towel. This prevents sweat and oils from soaking into the wood.
  • Deep Cleaning: At least once a month, clean your sauna thoroughly. Use a mild solution of water and soap. Avoid harsh chemicals as they can damage the wood and release unwanted fumes during the next heating.

2. Keep it Dry and Ventilated

Humidity can be a sauna's enemy. Ensure you:

  • Ventilate the Sauna: After each session, leave the door open for at least an hour to let fresh air in.
  • Use a Floor Mat: Placing a cedar or eucalyptus mat on the floor will absorb excess moisture and prevent mold growth.

3. Check for Wear and Tear

Regularly inspect your sauna for:

  • Cracks in the Wood: Small cracks can expand over time. Repair or replace damaged wood promptly.
  • Heater Elements: Check for any signs of damage or corrosion and ensure they're functioning properly.
  • Door Seals: Make sure the sauna door seals tightly, retaining heat and keeping external moisture out.

4. Mind the Stones

If you have a traditional sauna with stones:

  • Rinse the Stones: Every few months, remove the stones, rinse them to remove dust and debris, and dry them thoroughly before replacing.
  • Replacement: Over time, sauna stones can deteriorate. Replace any cracked or crumbling stones to maintain efficiency.

5. Treat the Wood

  • Avoid Stains: Use towels on benches to prevent sweat stains.
  • Oil Treatment: Once a year, consider treating the wood with a sauna-specific oil. This preserves the wood's color, prevents cracking, and provides a layer of protection.

6. Maintain a Stable Temperature

Consistent overheating can damage your sauna's interior. Always monitor the temperature and avoid letting it get too hot for extended periods.

7. Replace Parts When Necessary

Quality saunas are built to last, but parts can wear out. Regularly inspect components like heaters, control panels, and lights. Invest in quality replacements to ensure longevity and efficiency.

8. Stay Clear of Harsh Chemicals

Whether cleaning the sauna or adding fragrances, always choose products designed for saunas. Non-specialized products can damage the wood, affect indoor air quality, or pose a fire risk.

9. Professional Inspection

Consider hiring a professional for an annual inspection. They can spot issues that might go unnoticed and offer solutions for optimal performance.

10. User Etiquette

Educate all sauna users about proper etiquette:

  • Shower First: This reduces the introduction of oils and dirt.
  • Avoid Spills: Liquids, especially colored beverages, can stain the wood.
  • Limit Usage: Overuse can lead to excess wear and tear. Encourage breaks between long sauna sessions.


A sauna is an investment in relaxation, health, and well-being. Like any other investment, it requires care and attention. By following the above sauna maintenance tips, you can ensure that your sauna remains in top condition, offering endless hours of relaxation and showcasing the myriad sauna benefits.
