One disclaimer before we begin…we don’t have any experience building an infrared sauna but we do have ideas on how it could be done. Kindly consider all the information in this article as a starting point.

That said, let’s get started…

Components Required For Building Your Own Infrared Sauna

There are 3 major components that you’d require. Those are – 

1. Sauna room/tent
2. Infrared bulbs or heater
3. Other accessories 

Below we are going to dive into each component and give you some idea of how to build the sauna. But first, consider the size of the sauna – 

Consider the Sauna Size

Ask yourself: Who are you building it for? If the answer is: my family then let’s take a step back. 

Most of you reading this article are beginners, i.e. you have never built a sauna before (If you had, you’d be writing this article, not reading it). And the fundamental rule of learning is to start small. DO NOT try and build a sauna for 5 people on your first attempt. We strongly recommend beginners construct a small one-person sauna room for personal use before moving on to larger projects in the future. 

Now, let’s begin with the first step. 

1. Building The Sauna Room

You can either custom-build a sauna room, or buy a pre-built enclosure, or simply use an existing room.

Prebuilt sauna rooms are expensive. You would have to spend at least $1000 for purchasing a sauna room. Custom-built rooms can be cheaper but only if you are building them on your own. 

Our recommendation –

Go for an existing room like a closet. Ideally, the room should be small with a low ceiling. 

Alternatively, you can purchase a gardening tent or a privacy tent. The privacy tent will have to be covered with foil insulation on the inside. To make sure that the structure is in place and not falling away at the slightest touch use tapes

Another way to build the sauna room is to simply construct a wooden structure and then cover it with foil insulation. Below, we have included an image that’ll give you some idea of what we are implying. 

As for the type of wood, use soft and heat-resilient woods like birch, basswood, and spruce.

2. Choosing Infrared Light Bulbs or Heater

On Amazon, there are plenty of infrared bulbs and infrared heaters available for purchase. We recommend the bulbs because they are ideal for a small sauna room and they are way more affordable than heaters. 

Please ensure that you are choosing light bulbs that produce both orange and near-infrared wavelengths so that you can reap the benefits of both photobiomodulation and near-infrared lights. 

You’d also want to make sure that they have a minimum of 250 watts of power. 

Infrared bulbs come at various price points. You can get them for as cheap as $12 to as expensive as $90. The cheap ones as they might not have enough power, produce the wrong wavelengths, and produce too much EMF. Hence we suggest, going for bulbs that cost more than $20.

Next, you’ll need to find something to hang the blubs onto like a clothes or shoe rack. Then plug the bulbs into an extension cord and you should have your infrared lights ready. 

Alternatively, you can grab some lamp fixtures and lamp clamps to set the blubs at convenient angles. Just make sure that the lamp supports the voltage of the bulb.

3. Other Accessories

You will need a wooden stool or a camping chair to sit inside the sauna. 

You’ll be sweating a lot so carry a clean towel. Also, make sure your hair and eyes are protected with a head cap and goggles.


Below we have answered all your burning questions about building your own infrared sauna from scratch – 

What Is the Size of a DIY Infrared Sauna Room?

The size of a DIY infrared sauna room should be 4’x4′ or 5’x5′. And the ceiling should be no bigger than 6’. We recommend these sizes for anyone building a sauna room for the first time. 

What Kind of Power Supply Is Required?

You need a 120v outlet to power your infrared bulbs but if you are located in a country where 240v outlets are the norm, purchase your infrared bulbs accordingly. 

What Is the Expense of Building an Infrared Sauna on Your Own?

The cost of building an infrared sauna ranges between $100-$250. It depends on the choices you are making while buying components bulbs, chairs, goggles, etc. Try and use things you already have, for instance, an old shoe rack can be used to hang the bulbs. It’s a great way to reduce your expenses. 

Do You Need a Near Infrared or Far Infrared Heating Source?

A. This is really up to you to decide. Both near-infrared and far-infrared lights have health benefits. The near-infrared lights penetrate the skin on a surface level and improve cellular communication. When the body is exposed to far-infrared lights, it never absorbs more than it requires. Far infrared lights are known to heal the body from viruses and pain. We recommend learning about the differences between a near and far infrared sauna and then deciding which one is better for you. 

What Should Be the Temperature Inside the DIY Infrared Sauna?

The temperature inside the infrared sauna should range between 100-190 degrees F. That said, please be careful as high heat can cause severe damage to your body. 

How Hot Does the Infrared Sauna Bulb Get?

A. An infrared bulb can get very hot which is why we recommend caution while handling it. We also recommend keeping the bulb at a distance of 15-20″ from any object.

Do Infrared Saunas Use a Lot of Electricity?
