Outdoor Sauna Guide: Benefits, Setup, Protection & Choosing the Right Sauna Cover

If you’re considering adding a sauna to your home, an outdoor sauna is often the most practical and flexible option. While indoor saunas require space and remodeling, outdoor setups can be installed more easily and offer a wide range of sizes and styles.

However, choosing the right sauna is only part of the equation. Proper setup, maintenance, and protection are what determine how long your sauna lasts—and how much you actually enjoy using it.

At SaunaCovers.com, we work with customers every day who want to protect and extend the life of their sauna investment. This guide covers everything you need to know before and after installing an outdoor sauna.

Benefits of an Outdoor Sauna

Outdoor saunas offer more than just a place to relax.

Key benefits include:

• Stress relief and relaxation
• Muscle recovery after workouts
• Improved circulation
• A private space to unwind with friends or family

They’re also often more affordable and easier to install than indoor options.

How Do You Protect an Outdoor Sauna?

Protecting your sauna starts the moment you install it.

Step 1: Choose the Right Location

Before installation, consider:

• Available yard space
• Drainage and moisture exposure
• Sun, wind, and weather conditions

Smaller saunas tend to heat faster, but make sure you have enough room for comfortable use.

Step 2: Protect Exterior Materials

Outdoor saunas are constantly exposed to:

• Rain
• Snow
• UV rays
• Temperature changes

To protect your investment:

• Apply a high-quality exterior sealant
• Reapply every 2–5 years
• Use products designed specifically for sauna environments

Step 3: Maintain the Interior

Interior wood needs regular care.

Best practices:

• Wipe down surfaces after each use
• Use towels to reduce sweat buildup
• Clean regularly with mild, sauna-safe cleaners

Avoid harsh chemicals that can damage the wood.

Why a Sauna Cover Is One of the Most Important Upgrades

One of the most effective ways to protect an outdoor sauna is by using a high-quality cover.

A proper sauna cover helps:

• Prevent water damage
• Reduce UV exposure
• Keep debris off the structure
• Extend the life of the wood

What to look for in a sauna cover:

• Waterproof or marine-grade material
• Strong, durable construction
• Secure fit (elastic, straps, or Velcro)
• Proper sizing for full coverage

Important: A poorly fitted cover can allow water intrusion and reduce effectiveness.

For many sauna owners, custom-fit covers provide the best protection and long-term value.

What Should You Put Under an Outdoor Sauna?

A solid foundation is critical for longevity.

Recommended base options:

• Concrete slab (most durable)
• Patio or pavers
• Wooden deck
• Gravel base with treated wood

Never place a sauna directly on bare ground, as this can lead to moisture damage and instability.

Can Outdoor Saunas Be Used in Winter?

Yes—outdoor saunas work well in winter, but require extra attention.

Winter care tips:

• Remove snow from the roof
• Prevent buildup on the base
• Check for pooling water during thawing
• Use a protective cover when not in use

Even with a cover, heavy snow accumulation should always be cleared.

Can You Keep a Sauna Outside Year-Round?

Yes, most outdoor saunas are designed for year-round use.

However, long-term durability depends on:

• Proper installation
• Consistent maintenance
• Protection from the elements

Using a durable outdoor sauna cover when not in use significantly reduces wear and tear.

Can You Use an Indoor Sauna Outdoors?

In some cases, yes—but it depends on the manufacturer.

Important considerations:

• Exposure to moisture and weather
• Warranty limitations
• Material durability

Infrared saunas, in particular, are often not suitable for outdoor use unless specifically designed for it.

Why Barrel Saunas Are Not Insulated

Barrel saunas are designed for natural airflow.

Their shape:

• Circulates heat efficiently
• Eliminates the need for insulation
• Improves overall performance

Adding insulation can interfere with how they function.

Can a Sauna Be Stored Outside?

Yes, but protection is critical.

If storing outdoors:

• Keep the sauna covered
• Avoid prolonged exposure without protection
• Install as soon as possible after delivery

Proper protection reduces the risk of damage during storage.

How to Choose the Right Sauna Cover

Choosing the right cover is one of the most important decisions for long-term protection.

Key factors:

• Correct size and fit
• Durable, waterproof materials
• UV resistance
• Secure fastening system

What to avoid:

• Loose-fitting covers
• Thin or low-quality materials
• Covers not designed for outdoor use

Tip: Always measure your sauna carefully. Custom-sized covers often provide better protection than generic options.

Final Thoughts

An outdoor sauna can be an excellent investment—but like any outdoor structure, it needs proper care and protection.

Focusing on:

• Installation
• Maintenance
• Material quality
• Proper coverage

…can significantly extend its lifespan and improve your overall experience.

If you want to protect your sauna from weather, reduce maintenance, and improve durability, using a properly fitted outdoor sauna cover is one of the simplest and most effective upgrades you can make.
