A traditional sauna is more than a heated room. It is a centuries-old wellness ritual that combines intense heat, controlled humidity, natural materials, and a deliberate pause from everyday life. For many homeowners and studio owners, installing a traditional sauna becomes one of the most meaningful upgrades to their wellness routine.
This guide explains how traditional saunas work, how to choose the right system, and what to consider before installing one in your home or studio.
What Is a Traditional Sauna
Traditional saunas originated in Finland and remain one of the most authentic forms of heat therapy. Unlike infrared saunas, which use radiant light to warm the body, traditional saunas heat the air inside the room using hot stones warmed by a heater.
When water is poured over those stones, it instantly turns to steam, creating the characteristic humid heat known in Finnish as löyly. This combination of heat and steam is what gives a traditional sauna its deep, immersive experience.
Traditional saunas typically operate at higher temperatures than infrared saunas, often between about 150°F and 200°F (65–95°C), depending on personal preference.
Because of this heat level and humidity control, many users describe traditional saunas as more intense, more authentic, and more relaxing than other sauna styles.
Electric vs Wood-Burning Heaters
The heater is the heart of any traditional sauna. It determines how fast the sauna heats up, how the steam feels, and how convenient daily use will be.
Electric Sauna Heaters
Electric heaters are the most common choice for residential saunas. They use heating elements to warm sauna stones and maintain a consistent temperature.
They are popular because they are simple to operate, easy to maintain, and allow precise temperature control. Many modern electric heaters also offer digital controllers and remote operation, making them ideal for home environments.
Electric heaters usually require a dedicated 220–240V connection installed by a licensed electrician.
For most homeowners, electric heaters provide the best balance of convenience and performance.
Wood-Burning Sauna Heaters
Wood-burning heaters create a more traditional experience. They heat stones using a real fire, producing a distinctive aroma, sound, and ritual that many sauna enthusiasts appreciate.
These heaters are often preferred in outdoor or off-grid settings where electricity is limited. However, they require chimney installation, regular cleaning, and manual fire management.
Both heater types can produce excellent sauna heat. The choice usually depends on lifestyle, installation location, and personal preference rather than quality alone.
Temperature and Humidity Levels
A traditional sauna is known for its high temperature combined with adjustable humidity.
Typical operating temperatures range between about 150°F and 200°F, while humidity levels are usually low until water is poured onto the stones. When steam is added, humidity briefly rises, creating a deeper sensation of heat without increasing temperature.
Many people enjoy sessions of 10–20 minutes followed by cooling off and repeating. The ideal temperature and humidity vary widely, and part of the sauna experience is learning what feels best for your body.
Size Planning
Choosing the right sauna size is one of the most important steps.
A sauna should comfortably fit the number of users without wasting energy. A two-person sauna may be ideal for a private home, while a four- or six-person sauna suits families or studios.
The heater must be sized according to the room’s volume. If the heater is too small, the sauna will never reach proper temperature; if too large, it can create uneven heat and wasted energy.
Planning space also means thinking about bench layout, door swing, ventilation, and safe clearance around the heater.
Power Requirements
Traditional saunas require significant power, especially electric heaters.
Most residential electric heaters run on 220–240V circuits similar to an electric oven.
This usually means professional installation is necessary. It’s important to plan power supply early in the design process to avoid costly changes later.
Wood-burning heaters require chimney installation, proper ventilation, and fire-safe materials instead of electrical connections. Both systems must follow local building codes.
Indoor vs Outdoor Installation
Traditional saunas can be installed indoors or outdoors, and each option has advantages.
Indoor saunas are convenient and accessible year-round. They can be installed in basements, garages, bathrooms, or dedicated wellness rooms.
Outdoor saunas provide a more traditional experience and allow cooling off in fresh air. They also avoid some ventilation and humidity concerns inside the home.
When planning installation, consider insulation, ventilation, drainage, and flooring. Proper design ensures the sauna is safe, efficient, and long-lasting.
Maintenance Tips
Traditional saunas are relatively easy to maintain when used properly.
Benches should be wiped after sessions, and wood surfaces cleaned occasionally with gentle products. Sauna stones may need repositioning or replacement over time, depending on usage.
Wood-burning heaters require ash removal and chimney cleaning. Electric heaters require periodic inspection of heating elements and stones.
Regular ventilation and drying prevent moisture buildup and extend the life of the sauna.
Traditional vs Infrared Sauna
Many buyers compare traditional saunas with infrared saunas before making a decision.
Traditional saunas heat the air and use steam, creating a hotter, more immersive environment. Infrared saunas heat the body directly at lower air temperatures.
Traditional saunas are usually preferred by users seeking an authentic Finnish experience or intense heat sessions. Infrared saunas appeal to those wanting lower temperatures and faster warm-up times.
Neither is “better.” They simply offer different experiences.
