A wood fired sauna is a timeless investment in wellness, offering an authentic heat experience and a warm, rustic aesthetic that electric models can’t match. To enjoy that deep, even heat for years to come, proper maintenance is essential. Routine care not only keeps your wood fired sauna safe and efficient but also protects your investment in a premium piece of wellness equipment.

Expert Tips for Getting the Best from Your Wood Fired Sauna
- Choose the right wood: Birch offers a steady, gentle heat and pleasant aroma; oak burns longer but requires more time to ignite; alder lights quickly and produces minimal smoke for shorter sessions.
- Monitor flue draft: Check that smoke flows cleanly upward if it lingers or blows back, your chimney may need cleaning or adjustment.
- Select durable stones: Opt for igneous rock like peridotite or olivine for longevity under high heat.
- Seasonal quick check:
- Winter: Sweep snow from the roof promptly to prevent sagging; keep pathways clear to avoid slips.
- Summer: Inspect for insect activity in the wood; ensure ventilation remains unobstructed in warmer weather.
How Often Should You Perform Daily and Weekly Care?
Clear ash and debris from the stove after each use to maintain airflow and consistent heat in your sauna. Choose kiln-dried hardwood such as birch or alder for clean burning, avoiding painted or treated wood that can release harmful chemicals. Check chimney airflow regularly to ensure unobstructed ventilation. Wipe benches and interior surfaces with a damp cloth or mild vinegar solution to prevent residue build-up. Sweep the floor to reduce dust circulation and leave the door slightly open after use to ventilate and reduce humidity.
If your garden space is compact, consider exploring the small wood fired sauna model for efficient heating and easy maintenance. A small hand brush can remove soot from the stove glass, keeping a clear view of the fire. Keep a bucket of water and ladle nearby for steam but avoid splashing excessive water on hot stones as sudden temperature changes can cause cracks.
For families or frequent users, a quick mid-week clean of high-contact areas such as benches and backrests can help maintain hygiene. You can also rotate sauna stones more often if you use the sauna daily to ensure even heat distribution and extend their lifespan.
Weekly checklist:
- Empty ash tray
- Check chimney draw is strong
- Wipe benches
- Leave door ajar to dry
What Monthly and Seasonal Checks Extend Lifespan?
Inspect stove seals and the firebox for wear. Check chimney integrity for cracks or blockages, and ensure sauna stones are free of fractures, replacing any that are crumbling. Rotate stones periodically for even heat distribution. Confirm proper water drainage around the sauna to prevent wood rot and brush off snow or debris from the roof to protect the structure.
If you host larger groups or have a more spacious garden, the large wood fired sauna model offers greater seating capacity and may require additional seasonal checks.
Inspect the foundation or base for sagging or shifting that can lead to long-term structural issues. Sand rough spots on benches and treat them with sauna-safe protective oil for interior longevity. Booking a seasonal service with our specialists will keep your sauna performing at its best. Learn more on our Servicing page.
How Can You Optimise Performance?
A clean, well-maintained chimney improves safety and heat efficiency. Have it professionally swept at least once a year to prevent creosote build-up. Store hardwood indoors or under cover to ensure it burns hotter and cleaner. Keep a spare set of sauna stones for deep cleans to avoid downtime.
If your household prefers a balance between space and heat-up efficiency, the medium wood fired sauna model can be an ideal choice.
Consider upgrading to a premium stove model with better heat retention or improved air intake design to further enhance performance. For outdoor saunas in windy locations, installing a chimney cap can prevent downdrafts and improve burn consistency.
How Do You Protect the Exterior Year-Round?
Apply sauna-safe oil or stain to exterior wood annually to protect against weathering. Inspect for mould or mildew and clean promptly with mild solutions. Trim vegetation back to allow airflow and prevent moisture build-up. If the wood fired sauna is near trees, fit a gutter or overhang to divert rainwater from the base.
For saunas in exposed locations, consider installing windbreaks or fencing to reduce weather impact. Regularly check the roof for signs of wear, and replace shingles or panels as needed.
When Should You Call the Professionals?
Seek professional help if you experience stove failure, significant heat loss, or visible structural damage. Inspections can identify hazards early and save on costly repairs. Arrange a visit via our Contact page. If your sauna has been in storage or unused for several months, a professional service can safely bring it back into operation.
What Safety Checks Keep a Wood Fired Sauna Running for Years?
Install a carbon monoxide detector in or near the sauna. Use only well-seasoned hardwood to minimise soot and creosote. Store fuel in a dry, covered area, and maintain safe clearances from surrounding structures.
Safety essentials:
- CO alarm working
- Extinguisher in date
- Fuel stack covered
- Clearances verified
