You can do Infrared Sauna yourself

If you Buying an infrared sauna cabin can be too expensive, especially if you’re not sure you’ll benefit from it. Infrared sauna blankets, bags or domes force you to lie on one place for half an hour and are not cheap too. However, another option exists - it is to do an infrared sauna yourself.

You can build it to prove yourself that infrared will give some benefit to your health before buying an infrared sauna cabin, or it can be a convenient way to have a home sauna when you have not much free space at your home.

Building a sauna yourself may involve doing some electrical wiring. Infrared heaters used in a sauna usually have high power requirements - as much as 1000 Watt. Please, do not try to build sauna yourself if you don’t know what you’re doing. If you’ll set up a sauna in a bathroom keep in mind that as a wet place it has strict requirements for electrical wiring safety.

Infrared sauna with two infrared heaters

First way to set up a home sauna is described by Jim Clements in his article The Bathroom for FIR Sauna, in which he explains how to use two infrared heaters placed in a relatively small room (5×11 feet suggested). He uses two 500 Watt 9 Amp infrared heaters from THMI, saying that these heaters give similar experience as in an infrared sauna cabin. He gives no specific information about this heaters aside from wattage and don’t know if any other brand of heaters will suit for this sauna set-up. Make sure that extension cord can safely handle power requirements of an infrared heater.

At pre-heating stage Jim recommends to turn heaters to a door or to a wall for heating to occur faster. Don’t place heaters too close to the walls or other objects due to the risk of inflammation. When the room is heated you can use it as a common infrared sauna, just go and sweat there. As an addition for two heaters Jim uses a 250 Watt infrared lamp hanged on the room ceiling (in his description he suggests to attach it to a shower curtain rod. Infrared sauna with infrared lamps
Another way to build an infrared sauna at your home is proposed by Dr. Lawrence Wilson. On his page about sauna therapy he describes how to use three 250 Watt infrared light bulbs to build an infrared sauna. Also you will need three ceramic or plastic lamp sockets for the bulbs, fifteen feet of heavy lamp cord, medium duty male wall plug and a switch, or better, timer-switch which is capable to handle seven amps current.

Sockets should be wired in parallel. Connect socket wire to a switch. After attaching sockets to the board with screws you need to make a cover form hardware cloth to prevent bulbs from touching anything, also describes how to build an enclosure for your sauna with a set of pipes. The minus is that infrared heaters cost more than infrared heat lamps. This sauna’s safety depends on a skill of the person who made it and can be dangerous if done improperly.
Remember - safety first.
