Clearlight vs Radiant Health vs Heavenly Heat: Which Sauna Should You Buy?

After testing over 40 sauna brands, these are the three that consistently stand out. In this video, I break down what makes Clearlight, Radiant Health, and Heavenly Heat different from the rest—what works, what doesn’t, and who each one is best for. I’ve used all of these in real-world conditions across different climates for years, and this is what I’ve learned about long-term durability, heat performance, build quality, and EMF safety. If you’re deciding between premium sauna brands, this will help you make the right choice.

I tested Clearlight, Radiant Health, and Heavenly Heat, along with 39 other brands, and here’s what I found. You’ve seen the other videos, 700 videos on YouTube. We’ve tested a bunch of other brands that weren’t so great. These three continue to stand out year after year.

One because their product offerings are diverse, depending on your needs. One of them has something that works for you. Two, they work really well. Detoxification is on point.

User experience is usually pretty good, aside from the app thing. Only some of them have the app trouble. I think they’re working that out. And then outdoor, indoor, small, medium, large offerings, definitely a good selection for everyone.

Right now in here, side by side, just to do a quick comparison, I have the Clearlight and the Radiant Health. This is not an apples to apples comparison by any means. That’s a one person. This is a two to three person.

But I’ll just talk about the brands in general, what I like, what I don’t like, just to give you an idea of something that might be good for you. First, Radiant Health. Let’s step inside real quick. Doing some testing in here.

Don’t mind all the gadgets and gear. Actually, don’t show all that stuff if you can. It’ll be in the courses in the upcoming video series. So Radiant Health, what do I like?

These things have been rock solid for six years for us, ever since 2019. I’ve owned multiple models. I’ve had them in Maine. I’ve had them in Florida.

I’ve had them in heated and cooled environments, and I’ve had them in raw environments. I’ve transported one over 1,500 miles in a U-Haul, basically torture tested it. It still works to this day. The only thing that’s ever broken on any of them that I’ve used is me dropping a camera mount, like a gigantic steel mount from head height onto the floor and just shattering a whole bunch of stuff, breaking, excuse me, breaking the camera thing also.

But it’s really no fault of the sauna. It was kind of user error. What I love about these is the heater layout, number one. The performance of them is second to none.

Look at it on a FLIR camera. We have videos about it. Basically, when you’re in here, your body’s wrapped in 360 infrared, especially a model like this. There’s heaters behind this wood panel here.

Facing me there’s heaters that go all the way to the floor on the sidewalls. There’s calf heaters There’s heaters in the floor and there’s heaters in the bench and there’s gigantic heaters on the sidewalls in behind you And out of all the Saunas that I’ve ever used something about this one and a lot of people say this too that have owned some of the other brands that we’re gonna talk about and then they bought one of these and they’re like I sweat better at a Lower temperature in this to me a lot of that signals heat distribution is a huge thing I found that to be true and thousands of other people have too.

So sometimes you worry about temperature on the screen But you don’t understand that Temperature on the screen is just thermostat measurement in the ceiling. Well, your body’s not up here Your body’s right here in the seated position So a lot of people are just thinking of temperature But that comes from a traditional sauna where you’re talking about just heating the air and air without moisture is a poor conductor of heat Right, you don’t have a lot of heat transfer or it takes a lot That’s why a lot of people are talking about Traditional saunas needing to be over 200 degrees or 180 in order to produce heat shock proteins this that and the other But really it’s not the air temperature that’s producing the heat shock proteins.

It’s the body response to the heat It’s your core temperature hitting that threshold which triggers the body to go through that Cycle and so how you do that doesn’t really matter You can do it with a jacuzzi or a hot bath Look up the PubMed research. A lot of people have limited thinking on this and they don’t realize that You know, they just think infrared versus traditional which one is better and it becomes like a war but what they’re missing is that the body itself has a Trigger point and once you hit that it’s like a thermostat once that hits the heater shut off and it goes through its cooling cycle The body’s doing the exact same thing.

You give it enough heat stress. It’s gonna hit that threshold and then bang it fires that response So how you get there doesn’t really matter But if you can be in a piece of equipment like this that has a high saturation of far infrared You’re gonna get there quicker regardless of what temperature is on the screen

And that’s what people are experiencing. They just don’t know it. When they have a better sweat response in this versus another brand. It’s hard for me to ignore that.

It’s hard, you know, maybe there’s a tech feature or something that looks cool or cool lighting or some wifi thing or whatever that’s great in some other sauna and you want to like it. But when you don’t get the body response like you do in this, you come back to this every single time.

Yeah, and of course we didn’t even mention it, but it’s, it’s kind of goes without saying any sauna from the certified sauna list qualifies as low EMF, low VOC, great build quality, you know, isn’t going to be a pile of crap. Radian Health Saunas specifically take the cake in almost every single area like that.

Other sauna companies like to say that they’re the lowest EMF, but from my testing, this is the lowest EMF sauna on the planet. Both magnetic, electric fields, RF radiation will be optional because you would have to put a Bluetooth transmitter in it in order to have any of that.

The reason that I like some of the dinosaur-ish tech in here is because it just works. It does not break. This thing is like a tank. Like I said, you can transport it across the country and as long as you don’t break the glass, it’s going to work for you.

So this is a Clearlight Sanctuary One. So I hate to do, I don’t really like to do brand comparisons in models side by side, because if you don’t have the same size and the same features and everything else, like you could come to this one and say, oh, well it has, you know, this tech feature, Radian Health doesn’t have that.

Or you could say, oh, you know, it’s not the same heater layout. Radian Health has that and this one doesn’t. Right, but if we were in a different size where they were both exactly the same, some of those comparisons would be different. So it’s not a fairness thing.

It’s more of an understanding thing. I don’t think the user necessarily understands that different heater layouts in different saunas in different sizes kind of don’t always mesh together. So just wanted to point that out. So Clearlight Sanctuary, what do I like?

What I don’t like? Um, number one, what I love about this is the look and feel.

If you’re somebody who’s claustrophobic or you like, you know, just something that looks cool. It’s pretty hard not to like this I mean, it’s crazy that it has an all glass front. There’s a compromise that comes with it, but aesthetically man It’s difficult not to like this. The lighting is great.

The fit and finish is great The sanding is good. The wood color is excellent the control panel the backlight. I mean Everything it’s a beautiful sauna. I really like them now.

That’s not to say it doesn’t come with a Negative point on that you get heat loss from the glass glass support insulator So you get a lot of heat less a lot of heat loss on the front We could go through the whole full spectrum thing, but I have other videos on that I don’t put a lot of merit in you know that particular wavelength I like far infrared and I like getting my red light therapy separate But that’s just a personal preference and a personal viewpoint doesn’t mean that clear light makes bad saunas.

They make great saunas I’ve been using them endorsing them for years now when you start getting into some of the tech stuff If you don’t have the right Wi-Fi network frequency and all this kind of stuff. The app is troublesome and stuff like that I’m not a huge app user though.

I don’t try to remotely control my saunas. I have a sequence I preheat the sauna I go make my sauna drink I go for a walk or I do my vibration plate rebounding or red light Therapy then I get in the sauna, so I don’t really need it to be on and stuff when I come home from work So I’m probably not the best candidate to talk about you know, Wi-Fi stuff and app connect connectivity if anything I don’t want it to be connected to certain things I really don’t like when you come in the house and your phone automatically connects to a Bluetooth set of speakers in here because the Stupid phone will ring with the doors shut and you’ll be getting texts and stuff and you don’t even know So I’m not saying anything about that unique to this brand I’m just saying if you have tech features and they’re enabled in that fashion.

It’s not really my favorite thing There’s a lot of detrimental stuff that comes along with that but back to the actual clear light sauna I mean the thing is beautiful. They have also a lot of accessories. You can do the sound therapy That’s a really cool add-on I don’t have it, but I really like that there are company that has forward thinking and incorporating stuff like

that because I built a sound table, I have done sound therapy, and I really like the idea of adding it, you know, to the sauna. What I’m saying is I love the ability to accessorize this thing. I like how it’s pre-built to add a heater on the door or red light therapy on the door.

We have separate videos talking about whether or not you should do red light therapy in the sauna. Just don’t want people to get confused. Just because you have a full spectrum sauna does not mean you’re getting red light therapy. So by no means is this an endorsement for you to look at a full spectrum sauna versus far infrared.

If you want red light therapy, I say get red light therapy from something that’s dedicated for that so that you know you’re actually getting it. That said, heater layout is pretty good. It could use a little work in the sanctuary because these get super, super hot, and then that makes this feel a little mild.

I also don’t have the same heat coverage like in a different sauna. Everyone argues about heater height. I think it’s a moot point. Both of them work.

I don’t think you’re wasting heat or it’s harmful above the head. I don’t think you’re condensing or controlling heat below the shoulders either. I think it heats adequately. In the all glass front saunas that aren’t 240 volts, I think they could use a little extra power on tap.

But like I said, it’s unfair to compare a one-person sauna to a three-person sauna that has very different power requirements, power supply, you know, everything else. But if you were to take a wooden front sauna and compare it to a glass front, the wooden front is going to outperform the glass every single time.

So for the beautiful look, there is a compromise in performance in order to get it, and that’s a decision that you have to make. I’ve talked about this at length in videos for years, so this is nothing new. Other than that, still love the company, like the product that they produce.

You know, there’s gripes here and there. There’s things that kind of drive me nuts depending on whether you work with a dealer or you buy direct. There’s kind of, you know, stories with each of them, but best thing you can do is look in the Facebook group. There’s 30,000 group members in there.

Thousands of them have clear lights saunas and are happy with them, and you can look at the reports and reviews and not just take from me on all these brands.

So let’s take a look at, since I’m bigger than this thing, let’s just get in it. Uh-oh, rainbow lights are on. Let’s talk about the Heavenly Heat Mini. So I guess we’re going to make this a little bit more of an unfair comparison even more, like I said before, because this sauna is obviously tiny.

So as you… One moment. Why is it doing it? Okay.

Well, now that I don’t remember what the hell I was saying, let’s make it even more unfair. Let’s step down to a mini sauna, a micro, an eco. I think they changed the name to eco sauna. Originally it was mini sauna.

I just call them all minis because I feel like a maxi in the mini. So let’s talk about Heavenly Heat. Heavenly Heat is another good company who outperforms the competition regularly. These saunas are built like absolute tanks.

The reason why I decided to come in the smallest one is because the build quality on this sucker is pretty extreme for the size. There’s no other mini sauna on the market that is built this well and this clean. They don’t use glues. And I have an argument.

There’s a con to me about that. I’d rather the sauna be built with Titebond II food safe wood glue because when I transport it in stuff and then it wiggles and jiggles, I don’t really want any brad nails coming loose. I don’t want pieces. And I’m not one of these people who’s so worried about the set point of the glue becoming liquid again because the sauna gets to 200 degrees or something.

It’s in a corner inside of a joint behind. It’s not like it’s in front of a heater. That would be my only gripe about these. Obviously that’s not what the company stands for.

And like I said, I point out pros and cons to everything that we try. And that would be one of the cons for me. I like glues. I think the construction longevity is better with it.

And if I were going to build it myself, it would damn sure have glue in it. So that aside, the build quality is really, really, really good. Heater layout is

exceptional. I’d love to see a heater on the back of the glass or a heater in the floor, but this thing gets so hot so fast you really don’t need it, right? But that’s just something like we talked about in the beginning of the video. That’s something that I look for in every sauna.

When you compare some of the cheaper saunas like the Costco sauna, that’s why some of these outperform those because they have a better heater layout, they’re built better, they have bigger power supplies, not all the time. But if you can do something like the Life Pro has done, where you get a $1,700, $1,500 sauna that has a great heater layout, it can become a contender with some of these higher-end saunas.

It’s just not going to have the same build quality, you know? There’s going to be stuff with the sanding. You can get splinters. The stuff’s not trimmed off well.

The heaters aren’t capped off. It’s not low EMF. They’re high EMF. They’re not zero VOC.

There is some other stuff in there. Heavenly Heat obviously addresses all of that. If you have MCS activation from anything, or you have severe allergies, or you have trouble with smells and compounds and cleaners and everything else, this is probably a really good option for you to look at.

Though we don’t have any issues with that in the Hemlock from Radiant Health either. The only thing that I would probably avoid is one of the stronger Basswoods or Hemlocks. Some other companies where they source their lumber is not the same. These guys pride themselves on having super low VOC, low EMF.

It’s not the lowest EMF in the industry, but it’s damn close. It’s good enough to where you don’t really have to worry about it. And then just the peace of mind for people that do have health challenges. There are no adhesives or anything in here.

I think they like that. For me, what I like about it is the performance. The performance is really good, and the build quality is really good. I have no question about the reliability of this thing because it’s built like a tank.

They don’t have corner saunas. They don’t have large saunas. They don’t have this. They don’t have that.

But you could say the same thing about the other companies. Oh, well, they don’t have a mini sauna, or they don’t have an outdoor sauna, or they don’t have this. So when we do these comparisons, it’s kind of like, yeah, it’s a brand comparison, but really it’s a you comparison.

too, because what are you looking for? What are your needs? Is there a company where we really think that they have longevity in the product, where you can buy it and you’re not gonna have to worry about it for the next 10 or 15 years? And that’s why we like these brands.

That’s why they take the cake. They are built better than other things in the industry, and you can tell when you use them all. The problem is you don’t have access to them before you buy. That’s why we do these videos.
