Far Infrared Sauna Heater Kits to build your own custom made wooden sauna.


Far Infrared Sauna Kits

Building a far infrared sauna can be rewarding and fun, as well as cheaper than a pre-built sauna. The project may seem a little scary at first, because the average person just doesn't build a sauna everyday. In reality, the learning curve is not that great. It is highly recommended that you have some basic carpentry skills and tools, or you can hire a handyman. A professional electrician is also recommended when it comes time for wiring.

On this page we'll tell you how to build a far infrared sauna and let you know where to find the parts you need.  For information on specific heaters, scroll down to the bottom to see what's available.

Why would I want to build a far infrared sauna?

Besides saving money, a far infrared sauna is a great investment in your health. Far infrared therapy is thought by many to be one of the very best methods for whole body therapy for lowering blood pressure, for pain relief, increasing energy and circulation and detoxification and elimination.

Far infrared heat is deep penetrating and helps dilate and expand peripheral vessels.  This can bring relief to soft tissue injuries and muscles through a faster production of healing compounds and increased circulation.  Better blood circulation leads to more oxygen-rich blood being delivered to injured areas, speeding up your natural process of recovery.  Many report that ongoing sauna therapy has lowered their blood pressure.

Parts you'll need

For your sauna you'll need wood, far infrared emitters, digital controller, housings and reflectors. Where to find wood depends on your location. Any building supplier in your area should be able to assist you in getting the right wood cuts for your project.

We can help you get the rest personally. You can either custom build your sauna completely and choose the number of emitters you use or buy one of our easy kits. Both are explained below.

Far Infrared Heater Kits

These kits are for people who want to build a sauna as simply as possible. There are three kits available depending on your needs:

One Person Kit: For one person saunas (3.5 feet by 3.5 feet). This kit includes a set of eight emitters with four housings and four reflectors, plus one digital temperature and timer controller. A dual controller is also available.

Two Person Kit: For two person saunas (4 feet by 4 feet). This kit includes a set of ten emitters with five housings and five reflectors, plus one digital temperature and timer controller. A dual controller is also available.

Four Person Kit: For four person saunas (4 feet by 6 feet). This kit includes a set of twelve emitters with six housings and six reflectors, plus one digital temperature and timer controller. A dual controller is also available.

Why would I buy a kit? It's all together, plus the kits are a bit cheaper than buying individual pieces. However if you are going truly custom with sizes not included above, you can get exactly what you need below.

Custom Sized Saunas

If the sizes listed with the kits don't match your needs, you can order as many sets of emitters you want. All you need to know is your cubic feet: length x width x height. This is the sizing formula, keeping in mind that you need to have approximately 17 watts per cubic foot:

If you'd rather skip the formulas, use our super simple Emitter Calculator instead.
(opens in a new window)

L x W x H - Cubic Feet
Cubic Feet x 17 Watts = Total Watts
Total Watts divided by 163 = Number of Emitters Needed

Because each set of emitters includes two, divide your number of emitters by two to see how many sets you need.

A quick example. If you want to build a sauna that is 4 feet x 4 feet x 6 feet:

4 x 4 x 6 = 96 Cubic Feet
96 Cubic Feet x 17 Watts = 1632 Watts
1632 Watts / 163 = 10 emitters needed, or five sets. Each set comes with two emitters, one housing and one reflector.

If your size requires an odd number of emitters, always round up. It's better to have one too many than not enough.

EMF output. Many customers ask this question. I have tested these and at 1" it reads 4-5 on the gauss meter. At 2" it reads at 2 or less.

This is a special order item: These items are usually in stock, but if not, please allow up to a 2-3 week lead time before being shipped to your location.

Standard Emitters are UL Approved and Terminal Blocks are CE Listed and recognized by UL. Your completed sauna as a whole will NOT be UL Approved. Some cities or counties may have strict electrical codes and you may wish to submit your plans for approval. We have UL and CE documentation we can fax to you. Seek the council of a professional licensed electrician before installing and wiring these units.   Promolife nor the manufacturer are not responsible nor libel for improper installation. Improper installation could create a fire hazard. Promolife does not council nor recommend any electrical wiring configuration. You will need a licensed electrician to professionally wire your sauna. Wiring diagrams are not included. The controller comes with a wiring schematic.  If installing these in commercial or industrial locations, we recommend contacting your local inspectors for initial approval. Promolife and the manufacturer is not responsible for inspection approvals.
