When most people think of saunas, their mind takes them to a tranquil spa where they can relax. Many medi-spa, salon, and gym saunas are incredible experiences and can provide a level of service, elegance, and quality that are unmatched. These are often high-end treats that are fantastic splurges, but might get expensive for daily use. There are plenty of home saunas that are fantastic as well. Manufacturers have generated a wide variety of designs and systems, including steam and infrared heat saunas. This article will explore the infrared sauna vs. traditional sauna, and determine which one is right for your needs and budget.
Saunas are now positioned at a wide selection of price points from very little money to a whole lot, but their helpful benefits are within the reach virtually everyone. You no longer have to worry about costly trips in order to just relax and unwind in the soothing heat of a sauna.
No matter if you’re planning on going to a spa for a sauna experience, or you’re considering a home sauna, there are a few key things you need to keep in mind before doing so, especially when it comes to the type of sauna you want. In this article, you’ll learn the differences between saunas, and find which type is best for your needs.

What is a Sauna?
What is it that makes up a sauna? The wooden walls? The steam? The hot hot heat? All of these play a part.
Traditionally, a sauna is an enclosed area that includes benches inside you can sit on while resting in extremely hot temperatures. Sometimes these are outbuildings, sometimes they’re closet-sized indoor structures, and more and more frequently, they’re personal portable tent-like devices.
The commonality of the sauna is the presence of high heat!
Infrared Sauna vs. Traditional Sauna vs. Steam Sauna
There are three common ways that heat is produced, through charcoal, through steam, and through infrared heat. Let’s look at each of these heat sources carefully.
Traditional Charcoal or Lava Rock Saunas
A classic sauna is traditionally built as a small room, often an outbuilding in Scandinavia (the above image is from a sauna in Estonia). The original incarnations of saunas were almost always heated by charcoal/wood. Steam was generated by pouring water over the charcoal, producing the steam.
Heat in traditional saunas is a very dry heat when the steam is not employed. Typically temperatures in charcoal-heated saunas are in the 180′ range and are quite hot.
Modern versions of these saunas are often barrel-shaped outbuildings with an electric sauna heater in them. These heaters heat sauna stones to a high temperature, which emulates the traditional charcoal. Steam can be poured on the lava rock for added humidity as necessary.
Steam Saunas (portable)
Steam saunas are heated not with charcoal, but rather by steam directly. Home steam saunas consist of a small closet-sized room that can be placed in a basement or other unused area (perhaps even outside) that expels steam into the enclosed room for heat.
Commonly these are built into showers, now.
Also, portable steam saunas are perhaps even more common. They consist of a tent that surrounds the body, connected to what looks to be a rice cooker that gets filled with water. This water is heated electrically, and the steam that comes off is funneled into the tent, where the tent is quickly warmed up to around 140-150′.
This type of heating is very wet and is certainly different from a traditional sauna. The experience of one of these saunas is akin to a Turkish steam bath or hammam.
Over the last 10 or so years, the infrared sauna has exploded on the scene, everywhere from high-end spas to inexpensive portable infrared sauns for home use. Infrared saunas are very low maintenance and offer a slightly different experience than a traditional sauna.
Infrared saunas are particularly attractive for home use. They are lower power (and lower temperature) than electric stove saunas, and don’t usually require a visit from an electrician to install. These systems use plug-in heaters to provide radiant heat in an enclosed space.
Infrared heat is safe, and is on the opposite end of the light spectrum from the ultraviolet light used in tanning beds (more on this below).
Infrared heats the body directly through radiative heat, as opposed to heating the air around the body. This means that an infrared sauna can be heated to a lower temperature than a traditional sauna (usually around 140-150′), while subjectively producing the same effects. This means that power consumption is lower, and as mentioned above, these don’t usually require specialized wiring.
Infrared heat is a dry heat and is more in line with a charcoal sauna than a steam sauna would be. However, many infrared heaters don’t function with sauna rocks, and cannot produce steam.
Who Named These Things, Anyway?
Unfortunately, the organization of the types of saunas can be a bit confusing: both lava rock style saunas and home steam style saunas use steam, but they use it in different ways. Lava rock or charcoal-burning saunas allow the user to add steam as needed; home steam saunas are heated only with steam.
Manufacturers often call lava-rock style saunas and rice-cooker style saunas “steam” saunas, but the lava-rock saunas only have steam as a byproduct of the heat. You choose how much steam you want, if any.
The rice-cooker style saunas heat the area itself with steam.
In this article, I’ll try to stick to calling rice-cooker style saunas “steam” saunas, and lava-rock style saunas “traditional” saunas.
The Benefits of Using a Sauna
There are numerous benefits to using a sauna, and if you start to look closely at the advertisements of various sauna manufacturers, you’ll get the impression that these setups work miracles. They can cure cancer, fix arthritis, make you lose weight, and give you fairy wings.
Yeah, not really.
While there are several scientific studies of sauna use, some of these claims are blown way, way out of proportion, and should generally be taken as preliminary.
The real benefit of a sauna is warmth, calm, relaxation, restoration, and rejuvenation. Whether you’re at a spa or at home, use your time in the sauna to get away from it all, and let that be your reward.
As mentioned above, there are many benefits that come with using a sauna, no matter which type you decided to use. Below are some of the most common benefits you can experience from it.
I’ll look at a few scientific claims as well as general benefits. Though for the most part, the science on the benefits of saunas is very preliminary, and you probably shouldn’t be purchasing one for purported health benefits alone.
A Sauna Bath Can Help You Relax
The warmth and sweat-inducing temperatures from any a sauna work almost magically to help calm your body and release it from tension and stress. Your body will release endorphins which can also help to make you feel happier.
Because it can work to significantly calm your body down, it makes it perfect for those who have high stress or anxiety. It can also help those with insomnia because it relaxes your body to help give you a deep sleep.
Keep the Technology AWAY!
Do your very very best to avoid technology while in your sauna, and use it as a time to quiet the mind and the body.
Use the sauna bath as a phone vacation.
Meditate in the sauna to help reach a relaxing, low-anxiety state. Take some time away from the world and pamper both your body and your mind.
Seriously, this right here is likely the most beneficial aspect to sauna use.
Imagine going to the spa for a relaxation massage, and spending the whole time on Instagram. You should treat your sauna time in the same way, even if its a tent in the basement.
Correlation Between Traditional Sauna Use and Longevity
Here’s one study covered by Harvard Medical School. It’s a pretty interesting study of 2,300 Finnish men, performed over 20 years (i.e. a good study!) found that “frequent visits to a sauna were also associated with lower death rates from cardiovascular disease and stroke.”
This study focused on the traditional style sauna with lava rocks and poured-water steam, as opposed to infrared saunas or portable steam saunas.
It’s unclear whether the findings would carry over to either of those style saunas, and it’s hard to say how much of this is a correlation or causation.
Nonetheless, it’s worth mentioning!
Saunas May Improve Circulation and Vascular Health
There is some potentially good news for those who need help with circulation, and perhaps this is tied to the longevity point mentioned above. That said, the science on this one is super preliminary.
A few studies of those who already have cardiovascular problems have found there may be improvements in cardiovascular function after regular infrared sauna use. It’s unclear what the mechanisms are that cause this improvement, but regardless, benefits have been found.
A sauna can increase your heart rate due to the high temperatures which in return can improve your circulation. This means it can help with various types of circulation problems, like arthritis, as well as muscle soreness.
Potential Immune System Benefits
There is some evidence that traditional saunas (note: not necessarily infrared or steam-heat saunas) may improve immune system functioning, and could potentially even help in fighting the common cold.
The heat from a traditional sauna can raise your white blood cell count. This could improve the efficiency of the immune system.
Again, this science is quite preliminary.
Detoxification — Have you Had Your Toxin Level Checked Recently?
It’s not hard to find lots of promotional materials explaining that saunas will remove toxins from the body! Some sites will even link to studies showing that time in a sauna will remove heavy metals and other toxins from the body. Well…
Look, if you have toxic levels of heavy metals like lead in your body, you need to see a doctor immediately. A sauna’s not gonna cut it!
Yes, sweating will release minuscule amounts of heavy metals, and yes, you sweat rivers in a sauna. So yes, your body expels toxins.
Pointing to this aspect of sweating as a benefit of a sauna is gobbledygook, and should be ignored.
What Type of Sauna is Best?
Most any sauna found in a spa or medi-spa will be extremely high quality, and custom sauna designs can be a feast for the eyes as well as the body.
If you’re looking for a home sauna, you’re most likely deciding between an infrared sauna and a steam sauna. Unless you plan on building an outbuilding or barrel sauna kit housing an electric or wood-fired sauna, most of the saunas on the market are either infrared or steam-heated.
Wet Sauna vs. Dry Sauna
Wet saunas aka steam saunas are ideal for those who really like the feeling of hot steam in their respiratory system. The steam can loosen phlegm, improve congestion and the sinuses. Dry heat saunas like lava rock or charcoal-burning saunas produce a powerful, dry heat that can be tempered with steam as needed.
If you’re looking to replicate the heating design of the lava rock or charcoal-heated sauna at home, you’ll probably want to stick with a sauna powered by an electric stove.
If you’re ok passing up the steam features, an infrared sauna will be an excellent choice as well.
Most of the science that has been done on sauna use tends to be on dry saunas, so if you want to aim for health benefits, sticking with dry is wise.
If you like the idea of the steam sauna, are always congested, and seek the moist heat it provides, lean toward steam or traditional style saunas.
The Primary Advantage of Traditional Saunas
With a traditional lava rock or charcoal sauna, you get the dry heat, but you can add as much steam as you would like by pouring water on the rocks. The steam is a byproduct of the heat, not the primary source of the heat. This allows you to find the right comfort level for you in each session, and you can vary the humidity as needed.
With an infrared sauna, you aren’t getting the benefits of the steam, and with the rice-cooker style steam sauna, you’re only getting steam.
The flexibility is the major advantage of the traditional sauna. The major disadvantage is the price tag!
Home Sauna Cost
Home saunas can vary in price from a dinner for two at a pub to the price of a small car. Most portable saunas, regardless of the type of heat, can be had in the $60-200 range, while indoor wooden infrared saunas are typically over $1000.
CustomiIndoor traditional lava rock and steam saunas often run into the multiple thousands of dollars, depending on their design.
Outdoor barrel saunas and other outdoor saunas can easily go up toward $10,000 for a kit — and you’ll still have to assemble it!
However, the reality is that there is a sauna available at virtually any price point, so you shouldn’t let the price of the sauna deter you. You could always start small and then upgrade over time.
Common Types of Home Saunas
There are several major categories of home sauna commonly available. I’ll break them down here from generally least-expensive to most expensive.
All heat the body, though they do it in different ways, and certainly at hugely different price points!
Portable Steam Sauna
Portable steam saunas essentially consist of a tent that surrounds the body and a plug-in device that looks very much like a rice cooker that heats up water and transmits it inside the steam sauna. The steam quickly warms up the tent to somewhere around 150′ and brings on the benefits of a sauna.
These portable steam saunas are typically the cheapest saunas you can buy.
Yeah, they look a little weird, but they function reasonably well.
Portable Infrared Sauna
Portable Infrared Saunas are similar in design to steam saunas, but they don’t use steam for heat. Rather, they use infrared heat produced by electricity to produce a dryer heat than a steam sauna will produce. This infrared heat directly heats your body, as opposed to the air around your body, and will make you feel warmer than a steam sauna, even though the temperature is a bit lower.
Typically these saunas are priced more than a portable steam sauna but are still relatively inexpensive. Like the portable steam saunas, these function pretty well, but don’t have quite the panache of a wooden sauna room or spa!
And again, there’s no way to add steam to these systems.
Home Infrared Sauna
Full-scale wooden infrared saunas are typically priced much much higher than portable saunas are, as they are much more akin to full rooms than the tents in use in portable saunas. These saunas are often quite beautiful and minimal, and will certainly go a long way to getting the mind in the right frame for a sauna session.
Here’s some information on home infrared saunas. They’re usually priced much much higher than portable saunas, as they are full sauna rooms. However, they also don’t function with sauna rocks, and you don’t get the steam effect with these saunas.
Traditional Lava Rock and Steam Saunas
Indoor Traditional Steam Saunas are built on the same scale and design as the infrared saunas above but are heated using lava rocks and an electric heater for authentic style heating. Many of these units require 220v electricity to power up. This translates into a costly visit from the electrician to wire the unit up. However, they do produce fully authentic wet/dry heat.
Water can be poured over the lava rocks for steam. And this style of sauna perhaps most replicates the traditional experience while still keeping the structure indoors, and the prices from going crazy.
Outbuilding-Style Charcoal or Lava-Rock Sauna
Barrel Saunas and full-scale outbuilding saunas are a great choice for those who are able to shell out the coin. These are full-scale rooms (and some have multiple rooms) that provide authentic heating and an authentic look. They come in a kit and need to be assembled on-site.
Typically you can choose a heater: either a 220v electric heater or a wood-fired heater. Either provides an authentic sauna experience. But you’ll have to pay an electrician for the wiring on the 220v heater, and you’ll need to run the wire from the house to the outdoor sauna.
If you prefer the wood-fired heater, you’ll need to deal with the hassle of purchasing, chopping, seasoning, and handling wood.
How Different Styles of Saunas Work
One of the main differences is how these saunas work to help your body. A regular sauna, including a barrel sauna or steam sauna, uses dry heat provided by charcoal, as well as steam from the water to help relax and soothe your body.
Portable saunas typically work in one way or the other: infrared heat for a dryer heat, and portable steam saunas boil water to produce steam for a wet heat.
Sauna Temperature Ranges
Another main difference is the temperature of the saunas. Inside a traditional sauna, temperatures can range anywhere from 150′ to 185’F while infrared saunas tend to be around 120′ to 140’F. So, if you’re not someone who withstand hot temperatures and humidity, an infrared sauna might be ideal.
Sauna Price Points
The price is also a major difference. Portable tent-style saunas look kinda wonky, but they work well enough for one person at a time to get the benefits of a visit to a sauna. However, it just isn’t the same experience as going to a room-scale sauna.
Infrared saunas are typically mid-priced and are the ideal solution for most who don’t want to spend a fortune on their sauna. A good in-home infrared sauna isn’t cheap, but it’s also not crazy expensive.
Traditional saunas are the most expensive, due to the design of the heating system, with the outbuilding-style barrel saunas being the most expensive and the most awesome. These saunas provide the most flexibility in moisture levels, however.
And of course a trip to a local sauna or spa may be the cheapest way for a single visit, and an outstanding way to get into saunas. However, if you plan to use a sauna frequently, you’ll need a membership or you’ll need to invest in a home unit.
How Quickly Saunas Heat Up
You’ll likely find that you need to wait longer for an infrared sauna to heat up than a traditional sauna.
Depending on the design, It can take up to 20 minutes for an infrared sauna to get to its peak while it only takes about 10 minutes for a regular sauna to do so.
Often infrared sauna users find that it’s best to crank the temp up to max before getting in. Step in at max temperature, and then immediately drop the temp to a more comfortable level, maybe 130′ or so, for the duration of the sit.
Can You Put a Sauna Outdoors?
Unless your sauna specifically says it’s rated for outdoor use, it’s generally only safely available for use indoors. If you really want an outdoor sauna, you’ll have to pick a sauna rated for it, typically a barrel sauna. These units are awesome but super pricey.v
Saunas and Safety
The main concern sauna users have regarding sauna safety is the length of time and dehydration. Additionally, some may have some concerns about being exposed to infrared light for long periods of time, but this in reality not a concern.
How Long Should I Stay in a Sauna?
How long you should stay in a sauna depends on several aspects.
If it’s your first time using a regular sauna, it’s recommended that you stay no longer than 10 minutes inside. This way, your body can become adjusted to the high heat. You can then gradually start to add a few minutes to your session afterward.
And if you’re new to saunas, check out our guide to sauna etiquette for tips on how to approach your visit to the sauna.
Type of Sauna
Overall, you shouldn’t stay in a traditional sauna for longer than 45 minutes, as it could cause your body to become dehydrated. The high temperatures translate into lower session times.
On the other hand, infrared saunas and steam saunas don’t require high heat levels. Because of this, you can stay in it longer and use it more often compared to traditional saunas.
Even still, if you feel light-headed, woozy, or anything like that, be sure to leave the sauna immediately, and drink plenty of fluids!
Infrared Light Exposure
As discussed in this article on infrared saunas, infrared light is safe for the body to be exposed to.
Infrared light is on the low end of the light spectrum and is on the opposite end of the spectrum from the harmful ultraviolet rays that are produced in a tanning bed, as well as those harmful rays from the sun that can cause skin cancer.
Conclusion: Infrared Sauna vs. Regular Sauna
If you’re looking for a way to help keep you calm and relaxed, whether you’re at home or at a spa, a sauna is an ideal option. This article explored two broad categories of saunas, infrared and traditional, and touched on the advantages and disadvantages of each.
Spa saunas offer magic that generally can’t be replicated at home (without spending tons of money!) and are great for occasional visits, maybe even frequent visits. But they tend to get pretty expensive for constant use. For that, it’s best to move to a home sauna.
If you don’t want to spend a lot, but like the idea of a sauna, stick to a portable personal sauna, probably an infrared sauna. They’re perfectly suited for home use and aren’t very expensive. In the middle price points, it’s best to move to a home infrared sauna room. These are expensive but will pay for themselves pretty quickly.
If you want to go all out on the traditional style, and its flexible moisture capabilities, you’ll probably want an outdoor sauna kit with a wet/dry heat environment and pleasant Scandanavian vibes.
