Key Considerations in Designing a Commercial Sauna

Selecting the Right Location

Choosing the perfect location for your commercial sauna is vital. It should be easily accessible, offer ample privacy, and provide a calming atmosphere. Additionally, consider factors like noise, plumbing, and electrical requirements when selecting the site.

Choosing the Sauna Type

There are two primary types of saunas to consider for your commercial space: Traditional Finnish saunas and Infrared saunas.

Traditional Finnish Saunas

These saunas use a traditional stove or heater to warm the space and typically have a higher temperature and lower humidity. They often feature a bucket of water and ladle for users to create steam by pouring water on heated rocks.

Infrared Saunas

Infrared saunas use infrared technology to heat the body directly instead of heating the air, which allows for a lower overall temperature. They are energy-efficient and provide a unique experience compared to traditional saunas.

Size and Layout

The size and layout of your commercial sauna will depend on your specific needs, space constraints, and the number of users you expect. Make sure to leave enough room for seating, walkways, and any additional features you want to include.

Materials and Insulation

Selecting the right materials and insulation is crucial for the longevity and efficiency of your sauna. Cedarwood is a popular choice due to its natural resistance to moisture and decay. For insulation, look for materials that can withstand high temperatures and prevent heat loss.

Heating and Ventilation

Proper heating and ventilation are vital to ensure a comfortable and safe sauna experience. Choose a heating system that is powerful enough to maintain the desired temperature and ensure adequate air circulation to prevent overheating and maintain optimal air quality.

Lighting and Ambiance

The lighting in your commercial sauna should create a relaxing and inviting atmosphere. Consider incorporating dimmable LED lights or even chromotherapy lighting, which uses different colors to enhance mood and relaxation. Don’t forget to choose fixtures that are suitable for high-humidity environments.

Safety Features and Accessibility

Incorporating safety features and ensuring accessibility are essential aspects of designing a commercial sauna. Some key considerations include non-slip flooring, proper handrails, and easy-to-use controls. Additionally, ensure that your sauna is compliant with the Americans with Disabilities Act (ADA) guidelines to accommodate guests with different needs.


Designing a custom commercial sauna requires careful planning and attention to detail. By considering factors such as purpose, audience, location, sauna type, size, materials, heating, lighting, and safety, you can create a unique and inviting space that offers a myriad of health and wellness benefits to your clients and guests.
