9 Features You Should Look For
in Your Next Indoor Sauna Kit
Shopping for a new indoor home sauna kit can be overwhelming. And considering the fact that indoor saunas are an investment, you will want to be certain you’re going to be satisfied with your purchase.
Knowing what features to look for will prevent wasting time looking at indoor sauna kits that aren’t a good fit. In this article, we’ll discuss the top 9 features you should look for in your next indoor sauna kit. Each will rank differently in importance for individual buyers, but all points are worth examining.

1. Ideal Wood Choice
When it comes to the ideal wood choice for your indoor sauna kit, there are some universally accepted principles to follow. The wood, for instance, should be:
-
Mold, water, and heat safe
-
Resistant to shrinking, expanding, and breaking
-
Durable and cost-effective
-
Aromatic with an aesthetic appeal
A few popular sauna wood options include the following:
Aspen
Aspen wood has a gentle earthy scent that will elevate your relaxation to a whole new level. It also doesn't splinter, secrete resin, or become excessively hot, which makes it ideal for your sauna seats.
Additionally, its light shade and matte finish make Aspen wood an attractive choice for a luxury indoor sauna kit.
Nordic Spruce
This light-colored conifer wood is sourced from Scandinavia, the birthplace of saunas. Its small tight knots, lack of odor, and rustic appearance make it ideal for use on the sauna's exterior walls.
Moreover, it’s also fairly smooth, which makes it smooth to the touch and pleasant to sit on in a sauna.
Canadian Hemlock
Canadian Hemlock is a part of the pine family of wood known for its knot-free, strong, long-lasting structure.
It emanates a gentle aroma and
as for its appearance, the combination of light color and distinct grain pattern looks immaculate and works well in all sauna designs.
Cedar
Cedar has a distinctive red hue and a classic aroma that you’ll definitely appreciate. Because of its natural humidity and mold resistance, this lumber is the most popular choice for both outdoor and indoor sauna kits.
It also does not leak sap, overheat, or deform when heated, making it another excellent choice for your sauna.
2. Size
Standard sauna sizes typically depend on the number of users. They include:

-
One-person indoor sauna kits: These are designed for a single person and are the easiest (and cheapest) to install. The best small traditional sauna is the Almost Heaven Logan 1-person Indoor Sauna Kit (pictured above). Though small in size, it packs enough benefits for that one person. The Almost Heaven Logan 1-person Indoor Sauna can be pre-assembled, and it comes with LED lighting functions of only 110 volts. Other than that, the floor you place it on can be any material except carpet. You can customize your indoor sauna kit to your tastes and preferences.
-
Indoor Sauna Kits of medium size: A medium sauna can comfortably accommodate 2 - 4 people, enough for a couple and their friends or a small family. This might be the best choice for those who plan to enjoy their sauna with one or two other people, or if you just prefer to have some extra stretching space. The Almost Heaven Grayson is a very popular indoor sauna kit for this reason – it is spacious without taking up lot of exterior room. This sauna model is pictured at the very top of this blog.
-
Indoor Sauna Kits of Extra-large size: Large saunas are the most expensive and take up more space in your home. The good news is that these can easily accommodate more than four users simultaneously, and also offer plenty of space to lie down inside if you prefer a spacious interior. These benefits make the investment in larger indoor sauna kits worth your consideration. If you want to go big, I would suggest the Almost Heaven Nordic 6-Person Indoor Sauna (pictured below). This huge traditional sauna masterpiece can comfortably hold six people while maintaining optimal flair.

So, What Size is Best for You?
The energy required to warm up and maintain high temperatures in a sauna is directly proportional to its size.
A standard traditional sauna for a family of four measures 6 x 5 feet and has upper and lower benches. Its average height is around 80+ inches, with a maximum allowable ceiling height of 96 inches. If you want to lie down, look for a sauna that's at least 6 feet wide in any direction.
The sauna should also have enough space so you can comfortably enter and clean it without feeling restricted. Generally, the rule is to add around two feet of seat space for each user to allow for a relaxing experience.
3. Aromatherapy for Indoor Sauna Kits
Another vital feature you should look for in your next indoor sauna kit is aromatherapy essential oils. If you are wondering why essential oils, you would be surprised at the various health benefits derived from these oils. Aromatherapy oils are known to aid in the following:
-
muscle relaxation
-
pain reduction
-
stress management
-
sleep improvement
Some of the most common and advisable essential oils are lavender, pine, peppermint, eucalyptus, lemon, cedarwood, birch, and cinnamon.
You can dilute essential oils in your sauna bucket before pouring it over the rocks. As the rocks heat up, the oil vaporizes and spreads the aroma throughout the sauna. To avoid overpowering the sauna, add only a couple of drops (3-3.5 drops per gallon of water) and gradually increase the amount till it reaches your desired level.
Aromatherapy can also be performed in a dry sauna by misting the air with essential oils.
4. LED Light Bar or Himalayan Salt Panel
Surrounding yourself with the right ambiance is good for your relaxation just as much as for your health benefits. Most people find relaxing spaces beneficial for a calmer mood.
You may want to choose a LED light bar to add to your indoor sauna kit. The Almost Heaven LED Light Bar is very versatile, and can be mounted on walls, both horizontally and vertically.
The light bar improves the ambiance and aesthetics of your indoor sauna kit. The light on a cedar deflector frame allows light to be directed along a wall or bench, which compounds the beauty of it all.

With the Almost Heaven LED Light Bar, you get up to 10,000 hours of lighting, which promises a long life and plenty of usage. If that is not enough, you can set the brightness to your desired level!
Folks who want to take things up a notch should consider investing in Himalayan salt-based products, like the Hotass Himalayan Salt Wall Panel.

Research shows that the potential benefits of Himalayan salt include improving mood, relieving pain, and helping you sleep better. If you equip your traditional indoor sauna with Hotass Himalayan Salt Panel, your sauna experience will be enriched by all these benefits.
5. Type and Size of Your Indoor Sauna Kit Heater
A modern-day indoor sauna kit is not complete without an electric heater. But the question is, how large of a heater do you really need for your sauna?
Well, this depends solely on your sauna’s size. If the room is large, you'll need a powerful heater with at least 6-8KWs of power, whereas a 4.5 KW electric heater would be ideal for a smaller space.
Wifi-enabled electric heaters can be controlled via an app on your phone or tablet. Some even come with Alexa or Google Home integration so that you can change their settings with just your voice.
Automating your home sauna can also help improve its efficiency by allowing you to set things like a heating curve or an automatic turn-off timer.
6. Floor kits
Most indoor sauna kits are designed to use your existing floor as their floor. So, you can place it on any level surface, including tile, concrete and vinyl (but no carpet!). If you want to improve the aesthetics of your sauna, floor kits are the way to go. The Almost Heaven Indoor Floor Kit is a great choice as it distinguishes your custom indoor sauna kit by giving it a more refined and personal appearance. Floor kits also protect your sauna floor from damage caused by sweat or moisture.
They come in various colors and styles — cedar, nordic spruce, aspen, and so forth — so you can choose the one that best fits your sauna and your personal tastes.
7. Thermometer and Hygrometer
A sauna temperature gauge is necessary for monitoring its performance and ensuring it’s hitting it’s optimal range for the best health benefits. The thermometer you buy should be accurate and easy to read, with a large dial and vivid digits. In addition, look for a sauna that has a hygrometer. It measures humidity levels and tells you how dry or wet your sauna environment is.
8. Timer for Your Indoor Sauna Kit
In such a relaxing environment, it is easy to get carried away and forget the passing of time. The solution? A sand timer! T Sand timers are graduated with 15-minute increments and can be mounted on your traditional sauna walls. The convenience of this timer is that they not only keep track of your time but can also withstand temperature and humidity. We offer three different brands, all of which are built to last: the Baltic Leisure Sand Timer, the Almost Heaven Sand Timer or the SaunaCore Sand Timer.
9. The Right Door
The door of a sauna is a prime example of how first impressions often last the longest. A beautiful entryway can transform an ordinary sauna into a regal work of art that stands out.
So, look for a door made of sturdy materials; or, if you want one with a bit more visual impact, choose one with metallic accents or etched glass to complement the overall theme of your sauna.

Some examples include the SaunaCore Sauna Door for SaunaCore models. It is made from durable red cedarwood that allows it to withstand wear and tear. The sauna door can be installed with bronze tempered glass for your safety and has a classic design to match your SaunaCore Indoor Sauna Kit. The EOD72 and EOD78 have full glass etched scenic designs. Others, like the Deluxe Fading Glass Door by Almost Heaven showcases beautiful fading glass for natural illumination plus privacy, while their All-Wood Door offers full privacy and exceptional insulation.
Final Thoughts on Indoor Sauna Kits
There is no denying the comfort of a steamy sauna after a long day at work. That said, the quality and features of your sauna matter and have a larger impact on this comfort than you might think. If you’re looking for the ultimate sauna experience at home, look for the right size, wood type, aesthetic, heating system, and accessories.
Also, if you want a lasting return on your investment, always invest in high-quality products from well-known retailers with good reviews and testimonials, rather than unknown brands.

I haven't even built this sauna yet (Rainelle), but I have to give an ENORMOUS shoutout to Adora and especially KELLY for their help on this one. This was a big purchase for us, and these ladies went way out of their way to make it work out for us. The first sauna that showed up was badly damaged in shipping, and from what it sounds like - that is not typical. At all. So Kelly helped us to get it squared away, and it took what could have been a horrible customer experience into a fantastic one. Give this woman a raise!
We really like our sauna! Quality of the sauna seems decent. The quality of the accessories was not! The back recliner was all busted up out of the box.
My wife and I would occasionally sit in the sauna at our gym after a workout. It was hot but a little gross. I can't tell you how many times we bailed on the gym sauna session because someone else was playing their phone too loud, someone was breathing like they were gasping for air, someone decided to be shirtless in public, someone is weird or any number of other reasons. Loved the sauna feeling but HATED the gym sauna.
We bought a sauna for our home and installed it in our basement to escape the gym sauna experience. We absolutely love it! We sauna daily. Without the angst and frustration of hoping to avoid an awkward gross experience at the gym sauna.
If you are considering a sauna purchase, spend a little extra and get the WIFI enabled heater. This is the best way to make sure you get the benefit of owning a sauna. The app on our phone is easy to use. Just click the on/off button on the app and set your temperature to your desire. I like 171. My wife likes 153. Once it hits the temperature, the app will let you know. You can even turn on your sauna while you are on the way home from the gym. The WIFI version and the app make all the difference in usability and enjoyment of your investment. If we did not have the app and the WIFI version, we probably would probably skip 2/3 of the sessions we currently take.
The sauna is well made. Wood quality is excellent. Very few knots and blemishes. Hillsboro Almost Heaven saunas are a great choice for quality components, solid electronics, easy to use controls and an enjoyable sauna experience.
This is a standard kit sauna. I made several modifications but I am very satisfied with it so far. I have a few shingles left to install tomorrow and then will move onto to interior. MSW has been easy to work with and I recommend them.
I really love this sauna. I use it about four times a week to help me wind down before bed and calm my ego. Customer service at MySaunaWorld was great.
Assembly took me roughly 8–10 hours total over two days, and I’m not a particularly handy person. The step by step instructions video was straightforward and easy to follow.
I paired the sauna with the HUUM Drop 9 heater (the largest HUUM Drop), and it performs very well. I hired an electrician to install it (about $900 extra). It easily heats the sauna to 190°F plus. I personally like it around 180°F, which it reaches in about an hour. Also, you can pour water over the hot rocks to make the air hotter and steamier. Make sure to mount it low so that it can heat everything above it. (I mounted mine 6” from the ground to the base of the heater.) I love that I can start heating the sauna from my iPhone, even when I’m not on my home Wi-Fi.
I got the double-bench configuration going across the back of the sauna which lets two people lay down. The area around the lower bench is cooler which is nice to have different temperature seating options.
The sauna looks fantastic, smells great, and feels solid. I would recommend this sauna to a friend.
We love our new Almost Heaven Pinnacle barrel sauna!
Delivery was perfect, the assembly was a breeze, and the sauna fits perfectly in our space.
The only regret we have is not to have made this purchase 10 years ago!
I had been thinking about installing a sauna for quite some time. I kept going back and forth between framing one in or a prefab that I assemble. I spent several weeks going over the various websites looking at designs for both and writing out the pros/cons for each. After much deliberation, I reached out to My Sauna World to purchase an Almost Heaven Greyson.
It came way sooner than expected which was a good thing, so I had to arrange for my electrician. I assembled it very easily, with my wife holding just one panel, and then I ran into a problem. The last wall was short. It took a lot of head scratching and measuring and remeasuring as well as back and forth communication with both My Sauna World and Almost Heaven. It turned out that I had been sent 2 glass panels that were the same dimension when the 2 glass panels are actually designed with different dimensions. The new panel was sent out without question, and the rest of the assembly went easy.
I will say that the folks at My Sauna World were extremely responsive and did a great job as liaison back to the manufacturer.
Overall, I had a really positive experience, and we are very happy with the Greyson with the Harvia Spirit 8kW stove.
We also have the duckboard flooring (that is a must) sitting on top of the concrete floor. The back and leg rest are also recommended.
Note: this is advertised as a 3-4 person but in reality it is a good 2 person. And lastly, I grew up with sauna my whole life, starting with my grandpa’s wood burning sauna. This non insulated Greyson type will not get up to the same temperatures, but it does get the job done. Very pleased with the product and do recommend (to frame one in my self and buy a pre-cut kit would have cost a few thousand more overall)
Their customer service is refreshing in a world where most companies fail miserably with service. They should teach customer service to other companies and government agencies. We have only tested the actual product to make sure it works, but along the way, we had multiple questions and the replies were quick and helpful. The sauna was easy to assemble.
Frankly, I was stunned at the quality of this product. Equally stunning is how easily everything fits together. It’s well and I’m looking to an improved lifestyle.
Back rests are a nice size and fit perfectly in my Lugano 3-person sauna. They are very comfortable (especially considering they are wood) and make sitting in the sauna an even more pleasant experience. To think that they were added in free to my purchase of the sauna is hard to believe. Very pleased with customer service from My Sauna World.com !
Well built, good quality, reliable, and matches my barrel sauna very well
I purchased this since it was significantly more affordable than from the brands website. It arrived quickly and is function perfect. It's easy to install and looks great. I had issues with water leaking into the sauna before that used to annoy me. Now it stays completely dry and the wood also is protected from damage and weathering.
The best Sauna ever, and the quickest delivery, 100% recommend !!!!
Works exactly as advertised. Easy install and perfect coverage. Highly recommend.
Very good customer service. My sauna came as expected.
