Indoor vs. Outdoor Sauna: Which One Is Right for Your Home?

Adding a sauna to your home is one of the best ways to create a personal wellness space. But one of the first questions many homeowners ask is whether they should choose an indoor sauna or an outdoor sauna.

Both options can provide a relaxing sauna experience, but the right choice depends on your space, installation preferences, lifestyle, and the overall look you want for your home.

What Is an Indoor Sauna?

An indoor sauna is installed inside your home, garage, basement, bathroom area, gym space, or dedicated wellness room. Indoor infrared saunas are especially popular for homeowners who want easy access year-round and prefer their sauna to be part of the home's interior design.

Benefits of an Indoor Sauna

• Convenient access from inside the home
• Protected from weather
• Great for home gyms, bathrooms, basements, or wellness rooms
• Easy to use during any season
• Can feel like a built-in luxury spa feature

Popular Indoor Sauna Models

• Finnmark FD-2 2-Person Infrared Sauna — full spectrum, indoor cedar
• Finnmark FD-3 4-Person Infrared Sauna — full spectrum, larger indoor spaces

Indoor saunas can be a great fit if you have an unused room, extra bathroom space, basement area, or indoor wellness space that can support proper installation and ventilation requirements.

What Is an Outdoor Sauna?

An outdoor sauna is installed outside the home, often in a backyard, patio area, garden space, pool area, or near a cold plunge setup. Outdoor saunas are popular because they create a destination-style wellness experience without taking up interior square footage.

Benefits of an Outdoor Sauna

• Does not take up indoor living space
• Creates a backyard wellness retreat
• Pairs well with cold plunge tubs, outdoor showers, or pools
• Available in beautiful cabin, barrel, cube, and modern designs
• Can become a standout feature in your outdoor space

Outdoor saunas are ideal for homeowners who want a spa-like backyard experience and have room for a freestanding sauna structure.

Space Considerations

Space is one of the biggest factors when choosing between an indoor and outdoor sauna. Indoor saunas require enough interior space, proper clearances, and a suitable location for electrical or sauna heater installation.

Outdoor saunas require a level location, adequate access for delivery, and a surface that can properly support the sauna. Depending on the model, this may include a concrete pad, pavers, deck, or other stable foundation recommended by the manufacturer.

Installation Differences

Indoor Sauna Installation

Indoor saunas may require more consideration around ventilation, flooring, electrical access, and the surrounding room. If the sauna uses an electric sauna heater, a licensed electrician is typically needed for installation. Read our sauna heater sizing guide to make sure you get the right kW for your space.

Outdoor Sauna Installation

Outdoor saunas may require site preparation before delivery. You may need to consider the sauna's foundation, access path, weather exposure, and proximity to electrical service if using an electric heater.

Design and Lifestyle

Your preferred sauna experience can also help guide your decision. Indoor saunas feel convenient, private, and connected to your daily routine. Outdoor saunas feel more like a destination and can transform your backyard into a wellness retreat.

If you enjoy the idea of stepping outside, cooling down in fresh air, or pairing your sauna with a cold plunge, an outdoor sauna may be the better choice. If you want the easiest access from your bathroom, gym, or bedroom area, an indoor infrared sauna may be more practical.

Maintenance Considerations

Indoor saunas are protected from rain, snow, and direct outdoor exposure, which may make exterior maintenance simpler. Outdoor saunas are built for exterior use, but they still need proper care based on the manufacturer's instructions.

For outdoor saunas, homeowners should pay attention to the foundation, drainage, weather exposure, and recommended wood care to help preserve the sauna's appearance and performance.

• You want easy access from inside your home
