The Ultimate Infrared Sauna Buying Guide

An infrared sauna will almost certainly be one of the larger investments you can make, not just in terms of value but also in terms of space. That’s why it’s so important to get this decision right. 

No one wants to feel buyer’s remorse on such a big purchase which is why we’ve put together this infrared sauna buying guide so that you are fully informed about making the perfect purchase.

What Is An Infrared Sauna?

Infrared saunas, as the name suggests, use infrared heaters to emit infrared light.

This invisible light penetrates the skin, gently heating the body from within which causes you to sweat as your body temperature rises.

The infrared heat helps to relax muscles and improve circulation. With better circulation, your skin gets more oxygen and nutrients while flushing out toxins. It’s like giving your body a refreshing, revitalising boost without suffering the intense heat of a traditional sauna.

Infrared vs Traditional Saunas

Today, traditional saunas are marketed as “electric saunas.” Heat is electrically generated, and rocks inside the sauna are heated to around 93°C (or 200°F). Typically, steam is created by pouring water over the rocks inside the sauna. In order to have the best experience using this sauna method, you will need to stay inside with the door closed.

Infrared saunas also use electricity, but much less is needed than with a traditional sauna. These saunas use infrared light to heat your body directly. As a result, your core is quickly warmed and takes less time than is required with its traditional counterpart.

Benefits of An Infrared Sauna

Infrared saunas have steadily increased in popularity and it’s not surprising as there are so many benefits.


There are a number of well studied health benefits that you can experience through the regular use of an infrared sauna. They can improve heart health, soothe your muscles, rejuvenate your skin, help your body expel toxins and even contribute to weight loss.

Typically it’s these various health benefits that convince people to give infrared saunas a try and once they realise how much better their body can feel, they rarely look back.


Infrared saunas aren’t just good for you, they feel good too. Most of our users have reported feeling comfortable and relaxed when using our infrared saunas. Much like traditional saunas, the warm environment can help you relax, but unlike traditional saunas, the infrared variety does not get nearly as hot. So, you’re unlikely to get so hot as to feel uncomfortable.


Unlike a traditional sauna, infrared saunas are both much cheaper and much easier to find space for. They do not need to be custom built, in fact Sun Stream Saunas provide complete simplicity so you know exactly what you are getting. 

Running costs are much lower and far less resource intensive compared to a traditional sauna too as they only need electricity and won’t cost a ton of it either.

Factors To Consider When Choosing An Infrared Sauna

Before you choose an infrared sauna, it’s important to consider a few factors first.

One of the first things you need to consider when buying an infrared sauna is how large you want it to be. Are you conscious of space and only need it for individual use? Or perhaps you want to invite friends and family to have sauna sessions with you. 

It’s important to consider how you intend to enjoy your new sauna before you make the purchase.


Going hand in hand with size is price. How much are you comfortable spending on an infrared sauna? While they are all a considerable investment, there will always be a level of variation in price.

Wood Quality

The quality of wood used is extremely important and goes some way to indicate the quality of your product overall. Materials like plywood are commonly used because they are cheaper but aren’t as good for insulation and longevity.

Sun Stream Saunas only use 100% FSC Certified premium-grade Canadian Hemlock. This beautiful wood offers unparalleled strength and stability as well as being hypoallergenic.

Safety Standards

Safety should never be compromised, particularly with a product that you will be inside. Your sauna should always meet all necessary safety standards as well as having low EMF and ELF emissions. Fortunately, Sun Stream Saunas have both ultra low EMF as well as the lowest ELF emissions on the market.


Any seller who has faith in their product will offer a warranty on their saunas meaning it’s a huge red flag when a company doesn’t offer one.

At Sun Stream Saunas UK, we offer a lifetime residential warranty because we are so confident in our saunas.


The heating in your infrared sauna should provide good, even heat and options for changing the temperature. Sun Stream Sauna’s offer 360° infrared body coverage to ensure a comprehensive experience as well as settings
