Traditional Sauna vs. Infrared Sauna: What’s the Difference?
Share your love
When shopping for a home sauna, two of the most common options are traditional saunas and infrared saunas.
Although both are designed to provide a heated environment, they work in very different ways. Traditional saunas heat the air inside the room, while infrared saunas use infrared heaters to warm the body more directly.
Understanding these differences can make it easier to decide which type of sauna fits your home, lifestyle, and personal preferences.
What Is a Traditional Sauna?
A traditional sauna, sometimes called a Finnish-style sauna, uses a heater to warm the air inside the sauna room.
The heater also warms sauna stones. In models designed for water use, small amounts of water can be added to the stones to create steam and temporarily increase humidity.
Traditional saunas typically feature:
- A wood interior
- Sauna benches
- A dedicated sauna heater
- Heated sauna stones
- Temperature controls
- Ventilation
The combination of high heat, wood construction, airflow, and occasional steam creates the classic sauna experience.
What Is an Infrared Sauna?
An infrared sauna uses infrared heating panels rather than a traditional sauna stove.
Instead of primarily heating the air first, infrared heaters emit infrared energy that warms the body.
Because of this heating method, infrared saunas generally operate at lower air temperatures than traditional saunas.
They are often designed as compact home units and may be easier to place in bedrooms, home gyms, or other indoor spaces.
How Do Traditional and Infrared Saunas Differ?
The biggest difference is the way heat is produced.
| Feature | Traditional Sauna | Infrared Sauna |
|---|---|---|
| Heating method | Heated air and sauna stones | Infrared heating panels |
| Air temperature | Generally higher | Generally lower |
| Humidity | Can increase with water on stones | Usually dry |
| Sauna stones | Common | Not typically used |
| Steam | Possible | Not a typical feature |
| Atmosphere | Classic sauna environment | More controlled indoor experience |
| Installation | Can require more planning | Often compact and convenient |
Neither option is automatically better for everyone.
The best choice depends on the experience you prefer.
How Traditional Sauna Heat Feels
Traditional sauna heat surrounds the entire room.
The heater warms the air, benches, walls, and sauna stones. As the air circulates, the entire space becomes hot.
This creates the characteristic sauna environment many people associate with traditional Finnish-style saunas.
Adding water to the heated stones can temporarily increase humidity and create a noticeable burst of steam.
For people who enjoy the classic combination of intense heat and occasional steam, a traditional sauna can be particularly appealing.
How Infrared Sauna Heat Feels
Infrared saunas operate differently.
Infrared heating panels emit infrared energy while the surrounding air generally remains cooler than in a traditional sauna.
Many users describe the experience as a more gentle or direct form of warmth.
Because the air temperature is lower, infrared saunas may feel different from the intense environmental heat of a traditional sauna.
This difference is one of the main reasons people choose infrared models.
Temperature Differences
Temperature is one of the most noticeable differences.
Traditional saunas commonly operate at significantly higher air temperatures.
Infrared saunas typically operate at lower temperatures because they do not rely on heating the entire room to the same level.
This means comparing temperature numbers alone can be misleading.
A traditional sauna may have very hot air, while an infrared sauna can provide a warm experience at a lower room temperature.
The heating technology is fundamentally different.
Humidity and Steam
If you enjoy steam, a traditional sauna is usually the better choice.
Traditional sauna heaters can be designed with stones that allow users to add water according to the manufacturer’s instructions.
This creates a temporary increase in humidity and produces the classic steam effect.
Infrared saunas generally do not use sauna stones or water in this way.
Their environment is typically dry.
Therefore, your preference for dry heat versus occasional steam can be an important factor when choosing between the two.
Sauna Design and Appearance
Traditional and infrared saunas also have different design characteristics.
Traditional saunas are often built with:
- Wooden walls
- Multiple benches
- Sauna stones
- A visible heater
- Larger interior spaces
They can create the appearance of a dedicated wellness room.
Infrared saunas are often more compact.
Many models feature:
- Enclosed wooden cabins
- Infrared panels
- Bench seating
- Glass doors
- Digital controls
Their compact design can make them easier to integrate into certain indoor spaces.
Space Requirements
Space can be an important consideration for homeowners.
Traditional saunas often require a dedicated room or structure, especially when using a larger heater and multiple benches.
Infrared saunas are commonly available in compact sizes, making them attractive for people with limited space.
Before purchasing either type, measure the installation area carefully.
Also consider:
- Ceiling height
- Door access
- Electrical connections
- Ventilation
- Maintenance access
The manufacturer’s installation requirements should always be checked before installation.
Installation Differences
Traditional sauna installation can involve more planning because of the heater, ventilation, sauna stones, and room design.
Depending on the model, you may need to consider electrical requirements and specific heater clearances.
Infrared saunas are often simpler to install because they use heating panels rather than a traditional sauna stove.
However, installation requirements still vary between models.
An infrared sauna may need an appropriate electrical connection, a level installation surface, and enough clearance around the unit.
Which Sauna Is Better for a Home?
There is no single answer.
A traditional sauna may be a better match if you want:
- Classic sauna heat
- Higher air temperatures
- Sauna stones
- Optional steam
- A more traditional sauna environment
- A larger dedicated sauna space
An infrared sauna may be more suitable if you prefer:
- Lower room temperatures
- Compact designs
- Simple indoor placement
- Infrared heating technology
- A more modern sauna setup
The right choice depends on what you want from the sauna rather than simply choosing the most popular option.
Which Sauna Is Better for Beginners?
Both can be suitable for beginners.
The main difference is the type of heat.
Traditional sauna heat can feel more intense because the surrounding air reaches higher temperatures.
Infrared sauna temperatures are generally lower, which some new users may find easier to tolerate.
However, individual comfort varies.
Regardless of sauna type, new users should start gradually and avoid staying in the heat longer than feels comfortable.
Traditional Sauna vs. Infrared Sauna: Cost Considerations
The total cost of a sauna depends on its size, materials, heater, features, installation, and brand.
Traditional sauna costs can include:
- Sauna structure
- Heater
- Sauna stones
- Electrical installation
- Ventilation
- Installation labor
Infrared sauna costs may include:
- Sauna cabin
- Infrared panels
- Control system
- Electrical connection
- Installation
A compact infrared sauna may have a lower installation complexity, while a larger traditional sauna can involve more components.
Rather than comparing the purchase price alone, consider the complete installation and long-term maintenance requirements.
Traditional Sauna vs. Infrared Sauna for Outdoor Use
Traditional saunas are commonly available as outdoor structures.
Their larger rooms and dedicated heaters make them suitable for backyards, gardens, and other outdoor spaces.
Infrared saunas are more commonly used indoors, although outdoor-capable infrared models are available.
If you want a backyard sauna surrounded by nature, a traditional sauna may offer more design choices.
For an indoor home gym or compact wellness area, an infrared model may be easier to integrate.
Which One Should You Choose?
A simple way to compare the two is to focus on your priorities.
Choose a Traditional Sauna If You Want:
- Classic sauna experience
- High-temperature air
- Sauna stones
- Optional steam
- Larger seating areas
- Indoor or outdoor installation options
Choose an Infrared Sauna If You Want:
- Lower air temperatures
- Compact design
- Simple indoor installation
- Infrared heating panels
- A modern home sauna setup
There is no universal winner.
The better sauna is the one that matches your available space and preferred experience.
