Planning And Building Your Sauna Room
A genuine Finnish sauna is relatively inexpensive, and it can be built to fit any space or surrounding. The size depends on the number of people likely to use it at the same time.
Ventilation in a sauna room is extremely important to achieve the utmost in satisfaction and pleasure. It will also speed up the reheating of the sauna room.
Lack of fresh air due to insufficient ventilation or poor management of ventilation can create an uncomfortable feeling. This often results in the symptoms of difficulty in breathing or burning of the skin.
The expanded hot air in the sauna contains proportionately less oxygen than the denser atmosphere outside. Bathers sometimes experience faintness unless the air is changed regularly. An amount of fresh air enters each time the door is opened; this is insufficient, however. Normally two ventilators are built into the walls.
The inlet should be located below the heating unit (Commonly a bottom gap in the sauna door or a door vent) and the outlet is located on the opposite side, on the ceiling, or just below the ceiling.
Recommended ventilation openings are 4” to 6” diameter, depending on the size of the sauna room.
Planning your room size:
Within reason, try to keep your room smaller rather than larger. After allowing for the depth of each bench, (typically 19" each) you should then plan on space for your heater, plus an area of 4" around the front, and two sides for the fence guard.
A smaller room will also permit using a smaller heater, smaller circuit breakers in your panel, and provide more efficient heating.
Planning the Sauna Room Layout:
- Plan the size of your room -- saunas can be virtually any size or shape. Hint: If you enjoy lying down in your sauna, allow 6' in at least one direction.
- Plan the door location and direction of its swing. A sauna door MUST swing out of the room, not into the room. Hint: For a better layout of the benches, put your door and heater on a long wall next to each other, if possible.
- Plan the location of your heater, preferably near the door wall. Remember that cool air will be naturally drawn from the door, along the floor to the heater where it will be heated and naturally rise to the ceiling.
- Plan the bench layout: Our normal bench depth is 20"; height is either 36" ( for the upper bench) or 19" high (for the lower bench). Custom sizes are welcome.
Hint: You will either sit or lie down in your sauna so include maximum benching as space permits; and note that the upper bench will be the warmer bench.
