Commercial Saunas Require Specialists in Design and Installation
Sauna size and specifications
– The sauna should be insulated to a minimum of R12 on the walls and R16 on the ceiling.
– Typical framing: 2 x 4 or 2 x 6. If metal studs are used, apply furring strips or plywood.
– Door rough opening to be 38” x 82” for handicap access.
– Dry wall per local building code.
– Finished floor as desired: Ceramic tile, stained concrete or vinyl. NO CARPET.
– Sprinkler system: Check local codes for verification.
– If you have questions about the above items, give us a call at 1-888-656-7008 or check local codes.
Inside Height of a Commercial Sauna
The minimum permitted ceiling height of a sauna is 77”. A typical ceiling height in the sauna is 84”. Check the minimum sauna height in the heater brochure or installation instructions. A maximum ceiling height as recommended by safety guidelines is 96”.
Commercial Sauna Benching
Benches in the sauna is a very important step. Maximizing bench space and minimizing wasted floor space adds to the efficiency of your sauna and maximizes the number of users for your space. Typically a sauna should plan for a lower bench and upper bench, with your upper bench area used as the main calculation for how many users you’d like to accommodate. Figure 2’ of bench space as typical for each sauna bather. Wood options for the benches and walls: Usually the seating boards are built from Cedar or Alder wood. Sauna walls are typically covered with Cedar or European Alder. There must be a 60” radius in front of the benches for handicap access.
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 the 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.
