    The word "SAUNA" is a Finnish word which describes the Finnish custom of bathing or deep cleansing by intense heat which induces perspiration.

    The word "SAUNA" is a Finnish word which describes the Finnish custom of bathing or deep cleansing by intense heat which induces perspiration.

    Technically, the term "sauna bath" refers to a specially constructed wooden room, properly insulated, and heated to temperatures of between 140° and 200°F (or approximately 71° to 93°C) to induce profuse sweating.

    BUILDING A SAUNA

    BUILDING A SAUNA

    In building a sauna, the two main factors to be taken into consideration are: (a) location of the sauna room and (b) the type of heat source to be used.

    With these two factors determined, one can then get into the other aspects of sauna installation which include size of the room, foundation and flooring, wiring, walls, ventilation, insulation, exterior finishes, safety measures and any accessories needed.

    Cost Analysis: Before undertaking the building of a sauna, all of the following data will need to be taken into consideration and a cost analysis must be done, based on building codes and local prices and accessibility of materials and equipment.

    In other words, cost analysis and planning is done first so that all the aspects of an effective, operational sauna are considered and provided for in advance. A properly targetted construction program can then be carried out rapidly.

    In the PAC area a very workable sauna was constructed for approximately $1600 – $1200 of which was for construction and construction materials $400 of which was for sauna unit heaters. With good planning, it is possible for any org to equip itself with a standard sauna room, vital to the delivery of the Purification Rundown. Its construction and maintenance should then more than pay for itself as the rundown is sold and delivered.

    Building Codes And Permits: It will be necessary to check with your building department to determine what permits are needed for sauna installation, and what the local building codes require in the way of structural design and construction materials. Most building codes in the United States set standards similar to or based on those of the Uniform Building Code and the National Electric Code for foundations, framing and wiring.

    Zoning laws may enter into it. However, as you will not be in the business of operating a commercial sauna and as many home owners and even business executives now install their own private home or office saunas, there should be no difficulty in obtaining the necessary permit for installation.

    Building codes and building permit requirements must be complied with, for both safety and legal reasons. It would be foolish for an org to endanger its tenancy of a building by any infraction of such regulations.

    Location Of The Sauna: A sauna room can be built inside another room. In other words, one could use a fairly small room for this purpose by insulating and paneling it properly, or one could partition off a part of a large room, with proper wall construction, insulation and interior finishing.

    An ideal selection for a sauna would be a room with a drain in the floor or one where a drain could be easily installed. It should be located near a shower (which may also need to be installed), as cooling showers may be necessary for a large majority of people during the hours of sweat out. In any case, a nearby source of running water is a must, as sweaters should drink plenty of water to prevent dehydration and this must be easily available. It is also needed for convenience in taking salt or potassium gluconate tablets and vitamins.

    Ideally, two showers and two locker rooms, one each for men and women, would be located conveniently near the sauna.

    Depending upon the type of heat to be used, it may be advantageous to select a room fairly close to the heat source to prevent the necessity for extensive additional wiring or piping. For example, if steam heat is used, the closer the room is to the steam furnace or boiler the better, as steam pipes, all well and properly insulated, would need to be run from the heat source to the sauna steam heaters. The more such piping is needed the greater the cost, naturally, and there is also the additional factor of it taking longer to get the steam actually coming through to the sauna heaters.

    An org. however, will want a sauna room that can accommodate between 10 and 15 people at once, as the traffic will require it. Some suggested sizes are: 12 x 10 x 7 feet; 14 x 14 x 7 feet; or 12 x 16 x 9 feet. The height of the room is never more than 9 feet, and most often 7 feet is best, as a high ceiling simply results in loss of heat, because heat rises. Thus a low ceiling prevents the heat from rising into space where it won't be used.

Otherwise, where steam is used only for central heating of the building, it would be far too expensive to run a steam boiler in the summer for sauna use only. Additionally, there would be heat loss, even with shut-offs to different areas. In a large building, however, where steam is required all the time for other purposes, steam would probably be the most economical. Or, it might be practical to purchase a small steam generator for sauna heating purposes only.

    With an electric stove, you will need at least a 220 volt supply of electrical power to the sauna. This is the same voltage that operates a kitchen stove or a clothes dryer, but it must be determined that the existing power supply in the org can safely support the additional power required for the sauna heater. If not, you may need to install an additional power supply.

    The size of the stove is important – it must be the correct size, power-wise, to produce the required sauna temperatures. The size will depend upon the size of the room and the location of the room. Less power, for example, would be required for a small room or a room with no outside wall exposure.

    The power of an electric stove is measured by the number of kilowatts needed to heat the stove elements. One kilowatt (kw) = 1000 watts. Prefabricated electric sauna stoves come anywhere from 2.2 kilowatts to 18 kilowatts in power.

    Prefabricated electric sauna stoves have a control unit that is always installed outside the sauna room, as the controls are not built to withstand high temperatures. These stoves usually also include a safety device that cuts off the electrical current should there be a malfunction of any kind.

    Gas Stoves: The power of a gas stove is measured by the number of British Thermal Units (BTUs) of heat the stove generates. (A British Thermal Unit is the amount of heat necessary to raise I pound of water I degree Fahrenheit.) Gas heaters are graded according to the number of BTUs they provide in one hour.

    Gas heaters usually cost less to operate than electric heaters. They are a bit more complicated (but not necessarily more expensive) to install. The heater would need to be connected to the building's gas supply line by approved gas piping. Standard approved galvanized steel pipe with threaded ends and standard galvanized steel fittings for any bends (elbows) in the pipe, with approved thread sealout, would be required. Such piping would need to be done professionally, possibly contracted, or inspected professionally when completed.

    Pressurize the line by opening the gas line valve. With a soft brush, mix up the soap solution and daub it well around any joints of pipe. If there is the slightest leak, it will show up in big soap bubbles. If any such leaks are found, the pipe connections would need to be redone, and then thoroughly reinspected.

    Both gas and electric prefabricated sauna stoves are metal-encased, usually with two or even three layers of noncorrosive metal with air between them. The outermost layer of metal, which is usually of stainless steel or baked enamel, prevents the surface from becoming too hot and inhibits the loss of heat from the front and sides of the stove. Both the gas and electric type stoves are thermostatically controlled.

    SAUNA STONES

    SAUNA STONES

    Prefabricated sauna stoves are designed with a metal tray at the top to hold and heat a pile of stones or rocks called konno rocks. Konno rocks, technically known as peridotite maim, are quarried in Finland. They are ideal for the sauna as they store heat well, help to distribute a soft heat evenly throughout the sauna room and help to maintain the required sauna temperature. Another virtue of these stones is that they can withstand high temperatures and do not crack or explode when subjected to high heat pressure.

    To allow for good air circulation, the stones should be loosely packed in the tray. If one wishes to add steam to the sauna, a long-handled ladle is used to pour water on the hot stones, resulting in bursts of steam which fill the sauna room.

    Wood Burning Stoves: Although the wood burning stove is in the best Finnish sauna tradition, it is highly impractical for org use. It takes a good quantity of wood to heat a sauna adequately and routine stoking would be required, as well as a convenient storage space for the wood supply. Further, the cost of wood as fuel can be high, and there is a wide variance in the heat-producing qualities of different woods. It takes considerable time to heat a sauna room to the required temperature with a wood burning stove, and the ashes from a wood fire must be removed periodically.

    A unit heater is a combination heater and fan, so arranged that the fan blows air through the heater, thus speeding the transfer of heat from the heater to the room air.

    Steam unit heaters are rated according to the number of BTUs they will produce when supplied with 60 degree F. entering air and 2 pounds per square inch steam pressure. As entering air becomes hotter, the heater puts out fewer BTUs. But by increasing the steam pressure to the unit heater you can increase the amount of BTUs it puts out. Check the steam capacity of the unit (which is probably 150 pounds per square inch). By adjusting the pressure reduction valve and so admitting more or less steam pressure to the unit heater, you can raise or lower the temperature of the sauna. A safety valve is used to protect the unit heater in the event that the pressure reduction valve should fail (though this is quite unusual). One should insist on clear instructions on how to mount any safety valve that is purchased.

    Actually, the unit heater can be heated by electricity, gas, steam or hot water. An electric unit heater is the easiest to install (depending upon the existing voltage supply, as described earlier) but an electric heater will use around 1/3 of a watt to put out one BTU per hour. To heat a room 14 x 14 x 9 feet high, this would require upwards of 18,000 watts per hour which, depending upon the geographical location, can be quite an expensive operation.

    Hot water heaters require high water temperatures, around 180 degrees F. minimum. Gas or oil heaters, depending upon local availability of fuel, can be fairly inexpensive to purchase and use, but they require sufficient air supply and the proper venting to be safe.

    Remember that any combustion including electrical combustion consumes oxygen and as oxygen diminishes it will give off carbon monoxide, which is quite a deadly poison.

    Perhaps your best bet, from the standpoint of safety and economy, would be a small steam generator, external to the sauna and well vented, providing steam to a unit heater in the sauna.

    CONSTRUCTION OF THE SAUNA

    CONSTRUCTION OF THE SAUNA

    Foundation And Flooring: The floor of the room you are converting into a sauna serves as the foundation.

    The room is then framed with 2 x 4 studs, spaced to permit insertion of 3-inch thick insulation batts. The studs are nailed to the wooden 2 x 4 sleepers below the subfloor. If the floor is concrete they are attached with anchor bolts or concrete nails. The studs may be 16 or 24 inches apart, according to building codes.

    Insulation: Good insulation is important in a sauna, as-it helps retain the heat and keeps the cost of heating down. The best insulation is expanded polyurethene. The insulation batts, 3 inches thick, come in strips, with flanges which can be stapled (do not use glue) to the framing studs. The 3-inch thick part of the insulation batt is inserted between the studs.

    Walls and ceiling are then covered with one-half inch gypsum board.

    For the final covering, walls and ceiling are paneled with saw textured l-inch by 6-inch wood paneling, with the smooth face exposed inside the sauna. Kiln-dried redwood is commonly used for such paneling, where it is easily available. This and cedar are especially popular because of their high insulation factor. They make the sauna easier to heat and remain cooler to the touch. Other low-density softwoods which resist heat can also be used, such as white pine, sugar pine, ponderosa pine, spruce and hemlock.

    Care should be taken to select finished, vertical-grain woods, as free of knotholes and resin pockets as possible. Any knotholes or resin pockets must be placed near the floor, never on the ceiling or high on the walls, as the melting resin could drip and burn the bathers.

    Building requirements usually call for a vent area of 1/20 the floor area, but not less than 1½ square feet, but this must be checked with your building department.

    The intake vent is located near the floor and can be approximately a ½-inch slit under the door. The outlet vent would be on the opposite wall, near the ceiling, and could be a vent of about 4 inches in diameter. With this arrangement, the good air is pulled in low in the room and can circulate, while the bad air leaves through the vent near the ceiling. It is a good idea to provide a slide cover for the outlet vent so it can be adjusted to control the amount of air leaving the room.

    Wiring: Any wiring to be done will have to meet very strict electrical standards for complete safety. The installation of wiring and electrical circuits to handle an electric stove (should your sauna have one), control panel, thermostat and lighting for the room, will probably be required to be done professionally. In a sauna wiring must be used that can hold up under 200 degree F. or higher temperatures and also withstand moisture. Also, the wiring must be located in the dry areas behind the insulation. All switches and controls are installed outside the sauna, as these do not withstand high heat.

    Sauna Door: The recommended door is a solid-core Philippine mahogany slab door. This is not a true mahogany and should not be too costly. It should be solidly mounted with 4 hinges and not too tight in the frame, as it will expand slightly, (or shrink), with changes in temperature.

    Curing The Sauna: Curing the sauna means preparing it for its first use. When your sauna is complete, sweep down and vacuum all walls, ceilings, floor, benches, corners. Next wipe all walls, ceiling, benches, fixtures, stove, accessories, etc. with a damp cloth and warm water. With the sauna door propped open, turn the heater on for about half an hour. (The stove may smoke a bit if it is burning off its protective coating.) Finally, close the sauna door, bring the room temperature up to 200 degrees F. for about 5 or 6 hours. Your sauna will then be ready for use.

    Hygiene: The sauna must be scrubbed down routinely to keep it sanitary and free from perspiration odors. Any duckboards on the floor should be removed and scrubbed and then replaced. It is also a good idea to routinely fully ventilate the room, particularly after heavy use, so wood surfaces can be given a chance to dry.
