How to Maintain Your Wood-Burning Barrel Sauna – Easy Upkeep for a Long-Lasting Experience

A wood-burning barrel sauna is a fantastic investment, offering relaxation, health benefits, and a touch of rustic charm to any outdoor space. The good news? Keeping it in top condition doesn’t require a huge effort—just a few simple maintenance steps will ensure your sauna stays in peak shape for years to come. Here’s everything you need to know about maintaining your barrel sauna without making it feel like a chore.

1. Air Out Your Sauna

Moisture is natural in a sauna, but good ventilation is key to preventing excess dampness and maintaining the longevity of your wood. After every session, leave the door slightly open to let fresh air circulate and allow the interior to dry out. This helps prevent mold and mildew while keeping the wood fresh and breathable.

Pro tip: On dry days, prop the door open for a few hours to keep humidity levels balanced inside the sauna.

2. Keep the Wood Clean

Your sauna’s interior will naturally develop a rich patina over time, which adds character and warmth to the wood. However, a quick wipe-down now and then helps keep it fresh. Use a damp cloth or soft brush to remove any sweat or residue. For deeper cleaning, a mild solution of water and vinegar works wonders without damaging the wood’s natural finish.

Avoid: Harsh chemicals or pressure washers—they can strip the wood of its natural oils and cause unnecessary wear.

3. Check Your Wood Burner & Chimney

A well-maintained wood-burning stove is the heart of your sauna. Every few weeks, check the firebox for ash buildup and empty it as needed. Ash can retain moisture, so keeping it clear ensures optimal burning efficiency.

Chimney maintenance is simple—just inspect for soot buildup overtime and give it a sweep if needed to prevent blockages. If you notice excessive smoke during use, it might be time to give the flue a quick clean.

Pro tip: Use dry, seasoned wood to reduce creosote buildup and ensure a cleaner, hotter burn.

4. Protect the Exterior from the Elements

Your sauna is designed for outdoor use, but giving it a little extra care will help it last even longer. A simple coat of natural oil or wood treatment once a year helps protect against UV exposure and moisture.

5. Monitor the Sauna Benches & Flooring

Since sauna benches and floors see the most use, they might need occasional attention. If wood starts to look dry, a light sanding can refresh the surface. Regularly check for any loose screws or shifting boards—tightening them up takes just a few minutes but keeps everything sturdy and safe.

Quick tip: Adding a small mat or towel on the bench during use can help reduce sweat absorption and extend the life of the wood.

6. Seasonal Sauna Maintenance

Twice a year, do a quick all-over check to ensure everything is in top shape. Look for any signs of wear, inspect the door seals, and give the exterior a fresh treatment if needed. If you’re in an area with heavy snowfall, brush excess snow off the roof to prevent extra weight on the structure.

Bonus tip: If you close the sauna for an extended period, give it a deep clean and leave a moisture absorber inside to keep the interior fresh.
