How to Care for Your Outdoor Sauna: Prevent Mould and Extend Its Lifespan

Considering an outdoor sauna for your garden? If so, you’ll want to know how to properly care for and maintain it to maximize its benefits and lifespan. Outdoor saunas offer relaxation and health benefits, but they also require regular upkeep to stay in top condition.

If you're unsure how to keep your sauna looking great while minimizing maintenance costs, keep reading! Whether you own a new infrared sauna or a well-loved traditional one, preventing mold should be a top priority. Mold not only damages the wood but can also lead to serious health risks. Thankfully, with proper care, mold prevention is easy, and your sauna will last for many years.

Why Mould Forms in Saunas

Mould thrives in warm, damp environments, making your sauna the perfect breeding ground. Outdoor saunas, in particular, trap humidity after each session. Without adequate ventilation, this moisture stays inside, allowing mold to grow on wooden surfaces, in crevices, and even on accessories like towels or cushions that don’t dry properly.

Signs of Mould in Your Sauna

• Visible black spots on wood surfaces
• A musty odor inside the sauna
• Mold hidden in hard-to-see areas, only becoming visible when it worsens
  
  

Understanding why mold develops helps you keep it under control, ensuring your sauna remains mold-free and safe to use.

What Mould Can Do to Your Sauna

Beyond health risks, mold can seriously damage your sauna. It weakens the wood, causing decay and long-term structural issues if not addressed. Preventing mold is key to maintaining your sauna’s integrity.

How to Prevent Mould in Outdoor Saunas

Follow these tips to keep mold at bay and extend the life of your sauna:

• Ensure Proper Airflow: Ventilation is the most effective mold prevention method. Make sure your sauna has at least one vent to promote airflow during and after use. After each session, leave the sauna door open for about 30 minutes to let it dry completely.

• Avoid Sealing or Painting the Wood: Never paint, varnish, or seal the interior of your sauna. This traps moisture inside the wood, creating ideal conditions for mold growth. Allow the wood to breathe naturally.

• Clean Regularly: After each use, wipe down the surfaces with warm water and a soft-bristled brush to remove sweat and dirt. Periodically, use a mild wood cleaner like Murphy Oil Soap for deeper cleaning. For mold or mildew buildup, scrub the area with a bleach and water solution.

• Drain the Sauna: If you have a traditional sauna, consider installing a drain to allow excess moisture to escape. This isn’t usually necessary for infrared saunas but is beneficial for high-moisture environments.

• Limit Water Use: When using sauna stones, avoid pouring excessive amounts of water over them. A cup of water every 15 minutes is usually enough to create sufficient steam without causing water buildup on the sauna floor.

Where to Place Your Outdoor Sauna for Maximum Longevity

Choosing the right location for your outdoor sauna can significantly extend its lifespan. To protect it from moisture damage, place your sauna in a dry area, away from water sources like pools or ponds. Make sure the space has adequate air circulation to prevent humidity from accumulating inside the sauna.

How to Care for Your Sauna Heater

Your sauna heater is crucial to its operation and should be regularly maintained. Clean the area around the heater with a dust cloth, and inspect it for any signs of wear or corrosion. If you notice damage, contact a professional for repairs. Always turn off the heater when not in use to avoid potential safety hazards.

Protecting Your Sauna from Weather Damage

Outdoor saunas are exposed to the elements, which can shorten their lifespan. To protect your sauna:

• Shield it from direct sunlight and strong winds: Sunlight can cause discoloration and dryness, while wind can damage the exterior.
• Cover it during rain or snow: Use a cover to keep your sauna dry and prevent water damage. Our store's Shingle Sheet Tiles are an excellent option for this purpose, providing a durable and protective layer against the elements.

• Use ventilation in summer: Excessive heat and humidity can damage your sauna’s components, so ensure good airflow during the hotter months.
