Frequently Asked Questions

Steam Sauna FAQ

What is a steam sauna and how does it work?

A steam sauna uses an electric heater filled with stones. When water is poured over the heated stones, it creates steam and raises humidity, producing the classic Finnish-style sauna environment with hot, humid air and an intense, invigorating heat.

How hot does a steam sauna get?

Steam saunas operate at higher air temperatures than infrared models. The exact heat depends on heater size, cabin volume, and insulation. Some users prefer short, high-intensity sessions, while others enjoy gentler heat with added steam.

Do steam saunas require plumbing?

No. Steam is created manually by pouring water onto the stones. There is no built-in water connection or drainage inside the cabin. The surrounding room simply needs normal airflow so moisture can dissipate when the door is opened.

What electrical supply does a steam sauna need?

Steam sauna heaters vary in power depending on the model. Many home heaters fall between 3 kW and 9 kW.
Important: Any heater above 3 kW must be hard-wired on a dedicated circuit by a qualified electrician. Always check the rated wattage before installation.

How long does a steam sauna take to heat up?

Typical heat-up time is around 30–45 minutes, depending on heater output, cabin size, insulation, and room temperature. Proper preheating allows the stones to reach the right temperature for consistent steam.

Do steam saunas create a lot of moisture?

Inside the cabin, yes — that’s intentional. Outside the cabin, moisture is minimal and usually released only when the door is opened. Normal room ventilation, such as a window or extractor fan, is sufficient to manage this.

Where can I install a steam sauna?

Steam saunas can be installed in indoor spaces such as home gyms, utility rooms, large bathrooms, or dedicated wellness rooms. Outdoor-rated models can be installed in gardens, on patios, or under shelter. Always check whether the sauna is listed as indoor or outdoor before installation.

Are steam saunas safe to use?

Steam saunas are widely used in both home and commercial settings. Stay hydrated, avoid alcohol before use, and leave the sauna if you feel unwell. Anyone with medical conditions, including heart issues or pregnancy, should consult a healthcare professional before use.

How often should I use a steam sauna?

Many people use a steam sauna three to five times per week. Beginners often start with shorter sessions of around 8–12 minutes and gradually increase duration as they become more comfortable with the heat.

Do steam saunas require much maintenance?

Maintenance is simple. Wipe down benches after use, leave the door open to help the cabin dry, and occasionally clean or reposition the stones according to the manufacturer’s guidance. Exterior wood treatment may be required depending on placement.

What’s the difference between a steam sauna and an infrared sauna?

A steam sauna heats the air and increases humidity for a traditional, high-heat experience. An infrared sauna heats the body directly at lower air temperatures. The choice comes down to whether you prefer intense heat or a gentler, deeper warmth.
