Benches in the sauna is a very important step. Maximizing bench space and minimizing wasted floor space adds toResort Sauna Design the efficiency of your sauna and maximizes the number of users for your space.

Commercial Sauna Doors

An all-glass door is quickly become the world standard as a stylish and durable option. The glass is resistant under high-heat, steam and fluctuations of wet and dry conditions. Also available are wood and aluminum doors with full glass.

Commercial Sauna Ventilation

Air mass that is colder than the surrounding temperature always tries to move downwards. Room-temperature air in Custom Fitness Center Designthe sauna ‘sinks’ down to the floor of the sauna unless it can be mixed with the air mass circulating inside the sauna. To get the natural draw effect and pull fresh air through the room, it is important to locate your in-vent directly under the heater so that the intense heat of the rocks accompanied with Helo’s open air heater design pulls the air into the room. By placing the exhaust vent as close to opposite your heater in-vent as possible your maximize air exchange and the level of the out-vent (typically 2’ off the floor) is low enough you have little heat loss, but high enough you’ll get good air exchange. For those who wish to use mechanical venting, please contact Helo’s technical staff or your local dealer for direct options related to your particular install.

Some Final Thoughts on Commercial Sauna Installations

Our design of commercial saunas incorporates thicker walls with more insulation and stronger benches to absorb more use. We recommend larger sauna heaters that have more rocks so the sauna heater can gently transfer heat to the sauna room.

Commercial saunas also require more sauna maintenance than home saunas. The benches and walls should be scrubbed weekly with a suitable cleaner. If they are not cleaned properly, bacteria can darken the wood and destroy wood fibers over time.

The rocks in the sauna heater should be taken out and rotated at least once every 3 months to restore proper airflow through heater and to get the most life out of the heating elements.

In commercial sauna installations we recommend sauna room sizes of 48 to 80 square feet. Utilizing this size sauna you are able to seat as many as six to ten persons at a time.

The minimum permitted ceiling height of a sauna is 77 inches. Commercial sauna rooms with an 8′ ceiling height are able to utilize a three level bench layout in order to gain the maximum seating possible. Maximizing bench space and minimizing wasted floor space adds to the efficiency of your commercial sauna and maximizes the number of users.


  • Carolina Sauna recently converted one of our walk-in closets into a Sauna. What started with an inquiry as to "is this possible" turned into an amazing reality. Tim Metzer and his team delivered us turn-key best-in-class service from first call to final installation. The craftsmanship is outstanding, cost was exact to the quote and the install team was very friendly and knowledgeable. Overall, the entire experience exceeded our expectations.

  • I am a single family custom home builder and Carolina Sauna recently completed the second sauna installation in the last 5 years for my company. In both installations, Carolina Sauna provided excellent service, quality materials and the attention to detail on the installation that my customers expect when building a high end custom home. Tim’s professionalism and communication with the home owner and builder prior to, during and after installation make my job easier and I look forward to working with Tim and CS on the next project.

  • We highly recommend Tim Metzer for any size sauna design and installation project. We have worked with Tim on two different saunas and have been more than pleased with each design. From the very simple design to the more elaborate designer space, he provides personal service, attention to detail and customization to fit the client’s needs.

  • Our builder introduced us to Tim Metzer of Carolina Sauna during the construction of our custom home. The service that Tim provided then was great, and he made the process easy. It has now been 6 years since we built, and whenever we need help with our sauna, Tim responds quickly. He has never made us feel that service ended when the sauna was complete. That is so rare now-a-days. We highly recommend Carolina Sauna to all, for we truly believe that Tim and his team will not disappoint.
