Constructing a sauna in your yard appears like a dream, doesn’t it? An ideal, cozy escape from the hustle and bustle of each day life. Someplace you may unwind, chill out, and benefit from the therapeutic advantages of warmth remedy. Not less than, that’s what I believed once I determined to tackle the venture of constructing my very own sauna.
I envisioned a fast weekend venture, a day of hammering away, and earlier than I knew it, I’d have a phenomenal little oasis of heat and wellness in my yard.
Spoiler alert: I used to be incorrect.
Seems that constructing a sauna isn’t so simple as throwing some wooden collectively and plugging in a heater. It’s a course of that requires planning, persistence, and an entire lot of studying alongside the way in which. I’m so glad I caught with it, regardless of the challenges and setbacks. The ultimate result’s greater than value it, plus I received some nice occasions with buddies, and also you get to learn this overly-detailed weblog submit!
On this submit, I stroll you thru my sauna-building journey, sharing the teachings I realized the laborious approach. From understanding the distinctive Finnish fashion of sauna constructing to selecting the proper warmth supply (and sure, a LOT about air flow). So, seize a cup of tea, get snug, and let’s dive into how I constructed my very own outside sauna—and what I realized within the course of.
Why Sauna?
Earlier than we bounce into the step-by-step of constructing a sauna, let me inform you why I made a decision to tackle this venture within the first place.
In case you’re something like me, you’ve most likely learn in regards to the quite a few well being advantages of sauna use. All the pieces from bettering circulation and relieving muscle stress to boosting your immune system and detoxifying your physique. I’ve stated many occasions that if the sauna have been a tablet, we’d all take it. However because it isn’t, I made a decision to construct one!
A 2015 Finnish examine checked out the advantages of sauna 4-7 occasions per week, and for this to be even remotely sensible, a house sauna is admittedly useful. After all, there are sauna kits and pre-made saunas, and I hyperlink to all those I’ve tried and preferred under. It’s really an embarrassingly great amount. However I like doing issues the powerful approach, so DIY it was.
Lesson 1: Planning Is Key (And Even Then, It’s Nonetheless Onerous)
The primary lesson I realized was that planning is essential in terms of constructing a sauna. Even with one of the best intentions, issues don’t at all times go as easily as you hope. I believed I had all the things mapped out completely. I measured the area in my yard, researched supplies, and even watched a number of YouTube movies on do it your self sauna constructing. A DIY sauna venture can be a weekend venture—nothing too loopy, proper?
However right here’s the factor: it’s simple to miss all of the small particulars while you’re caught up within the pleasure. The complexity of the sauna development began to turn into clear fairly rapidly. There are such a lot of components to think about while you construct it your self, from the muse to the insulation to the sauna door. One of many greatest challenges I encountered was getting the sauna to be correctly insulated. Saunas are all about retaining warmth. With out the correct insulation, all the trouble you set into constructing the construction received’t end result within the cozy heat you’re after.
I additionally realized that constructing a sauna is a bit like fixing a puzzle—it requires quite a lot of trial and error. Particularly while you’re working with totally different constructing supplies and determining how you can match all the things collectively. The method wasn’t quick, and it positively wasn’t simple, however the satisfaction of finishing one thing by handcrafted all of it value it ultimately. (Unrelated: I additionally realized that I’m not one of the best at spacial drawing and mapping out dimensions. Fortunately, that ended up all being fixable, although the sauna grew a few toes within the course of… whoops!).
The constructing supplies I used after a lot analysis:
- Untreated pine lumber because the body
- Smartside siding on the surface for sturdiness
- Mineral wool as a non-toxic insulation contained in the partitions (as a substitute of fiberglass)
- Aluminum vapor barrier on the within as soon as insulation was put in
- Exhaust fan for mechanical downdraft
- Alder wooden and a few cedar for the inside and sauna benches
- Two 4-light infrared panes from Creatrix for purple gentle and close to infrared: https://www.creatrixaffiliates.com/208.html (sure, this technically breaks the foundations of a pure conventional Finnish sauna, however my pores and skin loves it, so it’s staying)
- Huum heater (extra on that later)
These identical supplies can be utilized to refinish/repurpose an current outbuilding. Simply make sure all handled wooden and something that may offgas is sealed inside the vapor barrier. Or, as I did, these supplies can be utilized to construct a sauna from scratch.
Lesson 2: The Finnish Type of Sauna Constructing
Probably the most essential issues I found throughout this venture was the Finns fashion of sauna constructing. Finland is the birthplace of the sauna, and their conventional saunas are the gold commonplace for sauna fans worldwide. To really recognize the artwork of sauna constructing, I knew I needed to perceive the rules behind it.
In a Finnish-style sauna, there are two important parts that make it really distinctive: warmth and air flow.
Warmth: The Secret to Sauna Remedy
The warmth in a sauna is what offers you that satisfying, enjoyable expertise. It’s additionally what makes the sauna such a strong device for selling well being and well-being. When constructing my sauna, I had to consider how you can generate the proper of warmth. This wasn’t nearly selecting a heater (we’ll get to that later) however about creating an setting the place the warmth can be evenly distributed all through the room.
Conventional Finnish saunas typically use wood-burning stoves to generate warmth. Nevertheless, there are different choices, like electrical heaters, that may work simply as properly. The secret’s to make sure the warmth is ready to flow into successfully, making a constant temperature. That is the place the correct design and insulation come into play and the place I bumped into a number of hiccups early on.
With regards to the well being research on sauna advantages, the principle mechanism studied and recognized is the warmth itself. It’s up for debate if infrared sauna offers a “deeper warmth” or helps with detox. But the info is evident that with the correct amount of warmth and time, sauna may be very useful.
For that reason, I knew I had to verify the sauna may get to 170 levels at a minimal. I then added the infrared/purple lights as a bonus.
Correct Air flow: The Lacking Piece in Many Saunas
Now, right here’s one thing I didn’t absolutely recognize earlier than I began constructing my sauna: it’s not simply the warmth that makes a sauna efficient, it’s the air flow. Actually, I rapidly realized that warmth alone just isn’t sufficient to forestall fatigue or discomfort throughout sauna use. It’s really the CO2 buildup within the room that may trigger us to really feel drained or lightheaded. Try my podcast with Mike Feldstein the place we delve extra into CO2 right here.
To keep away from this, it’s important to have correct air flow. That is the place the downdraft system is available in. There are two important sorts of downdraft: mechanical downdraft and handbook downdraft.
- Mechanical downdraft makes use of a fan or vent system to flow into the air and take away extra CO2 from the sauna. This can be a extra fashionable answer and may be efficient in making certain the air stays recent and breathable.
- Guide downdraft is the normal method, the place you depend on strategically positioned vents to permit recent air to movement into the sauna naturally. Many pre-made saunas both don’t have air flow or depend on this sort.
I selected the mechanical downdraft technique for my sauna as a result of I knew we’d wish to have longer sauna classes and be capable to host greater teams. By putting in a vent above the heater and a fan underneath the bench, I used to be capable of enable for the right movement of air and maintain the CO2 ranges in test. This setup not solely made the sauna extra snug to make use of but additionally ensured that the warmth remained environment friendly.
Lesson 3: The Legislation of Löyly – Why I Selected Taller Partitions and an Elevated Bench
One of many key design selections I made when constructing my sauna was to go for a taller construction with 8-foot partitions. This choice was pushed by a deep respect for the normal Finnish sauna expertise and a need to honor the legislation of löyly—the tenet of sauna warmth distribution.
In Finland, the sauna is way more than only a room with a heater; it’s a ritual and a science. The Finnish idea of löyly refers back to the gentle, enveloping warmth and the sense of heat that fills the area when the sauna is correctly designed. It’s all about making a harmonious steadiness between the temperature and the airflow. This manner, the warmth circulates evenly all through the room. The legislation of löyly emphasizes the significance of warmth rising to the higher benches, making certain that the particular person sitting there enjoys one of the best of the sauna’s warmth.
In conventional Finnish saunas, the higher bench—the place individuals sometimes sit to benefit from the sauna—is positioned above the heater, permitting the physique to be uncovered to the most popular air. To make this occur, the sauna should have sufficient top to permit the warmth to rise naturally and envelop the person. I ensured that the higher bench can be positioned on the good top by choosing 8-foot partitions. This allowed my toes to take a seat at or above the extent of the sauna rocks, the supply of the warmth.
It wasn’t nearly creating extra room; it was about aligning the sauna with the rules of löyly. This positioning permits the warmth to rise and flow into across the physique, creating an immersive expertise of heat with out overheating or discomfort.
The Advantages of Taller Partitions and Elevated Benches
- Even Warmth Distribution: The primary motive I selected a taller sauna was to provide the warmth room to rise and unfold evenly. With the higher bench positioned increased than the heater and the person’s toes positioned at or above the extent of the sauna rocks, the nice and cozy air naturally fills the higher a part of the sauna. The air then creates a extra constant and mild warmth. This setup encourages higher warmth circulation. Your physique additionally stays heat from head to toe whereas avoiding the discomfort of sizzling spots or cool zones.
- A Extra Genuine Finnish Expertise: In Finland, saunas are an artwork kind, and the expertise is all about steadiness. Taller partitions and correct bench positioning make sure you’re sitting in the correct place to really feel the true essence of löyly. The rising warmth ought to fill the room naturally, creating that signature soothing heat important to the Finnish sauna expertise. After I sat on the higher bench of my sauna for the primary time, I instantly felt the distinction. There was a clean, enveloping heat that felt prefer it got here from throughout, not simply from the heater under.
- Improved Air flow and Airflow: By permitting the warmth to rise and flow into freely all through the sauna, the design additionally helps with air flow. Taller partitions create an area the place the hotter air rises naturally and the cooler air flows downward, selling the best alternate of air. That is particularly essential in conventional saunas the place handbook downdraft air flow performs a vital position in making certain recent, breathable air.
- Snug and Stress-free: When your toes are positioned at or above the extent of the sauna rocks, it additionally permits for a extra relaxed sitting posture. You’re not sitting too low to the bottom, which suggests you’re uncovered to extra of the nice and cozy, rising air. This setup helps create a extra snug and therapeutic sauna session. Right here you may really chill out and really feel the total advantages of the warmth.
Lesson 4: Selecting the Proper Heater
Probably the most essential selections I made through the constructing course of was choosing the proper heater. In any case, that is the guts of the sauna expertise. The fitting heater could make all of the distinction in terms of warmth high quality, vitality effectivity, and general expertise.
I did quite a lot of analysis earlier than deciding on a heater, and in the end, I went with the HUUM Hive heater. Right here’s why:
- Power Effectivity: The HUUM Hive is designed to be extremely energy-efficient. This implies I can take pleasure in lengthy sauna classes with out worrying about excessive vitality payments. It additionally heats up rapidly and evenly, offering a snug and constant temperature.
- Design: The smooth, fashionable design of the HUUM Hive matches completely with the aesthetic I needed for my sauna. It’s minimalist but trendy and provides to the general ambiance of the area.
- Efficiency: The HUUM Hive makes use of high-quality stones to generate warmth. This helps keep a constant temperature and create that gentle, enveloping heat I really like.
- Measurement: The HUUM Hive is available in numerous sizes, which was good for my sauna. I used to be in a position to decide on the correct measurement primarily based on the area I had obtainable and the extent of warmth I needed to realize.
The heater measurement could be very particular to the scale of the sauna and the specified temperature. This heater wouldn’t be applicable for smaller saunas and there are extra budget-friendly choices for heating smaller saunas. I used this heater from Vevor once I needed to exchange the heater in my barrel sauna.
Right here’s how you can calculate the scale of a sauna heater:
- Measure the quantity of your sauna room in cubic toes.
- As a normal rule of thumb, allocate 1 kilowatt (kW) of heating energy for each 50 cubic toes of area. Basically, divide the cubic footage by 50 to get the required heater measurement in kW. At all times spherical as much as the closest obtainable heater measurement if needed.
- You may also use a device like this one to calculate your heater measurement.
Lesson 4: Be taught Some Endurance
I feel one of many greatest classes I realized all through this course of is the significance of downtime and persistence. When issues don’t go in keeping with plan, it’s simple to get pissed off. Nevertheless, taking a step again and permitting issues to return collectively slowly could make all of the distinction. There have been loads of days once I was tempted to hurry via the venture, however ultimately, I’m so glad I didn’t.
The method of constructing my sauna took longer than I anticipated, nevertheless it gave me the chance to make changes, enhance my design, and be taught alongside the way in which. Now, I’m capable of recognize the top end result much more as a result of I understand how a lot effort went into making it good.
The Last Consequence
After months of labor (and a few occasional setbacks), my yard sauna is lastly full. Properly, apart from the ultimate roof, however that’s a narrative for one more day. It’s a comfy, heat, and alluring area the place I can escape from the world and give attention to my well-being. Each time I step inside, I’m reminded of the teachings I realized, the errors I made, and the enjoyment of constructing one thing with my very own arms.
In case you’re contemplating constructing your individual sauna, I hope this submit has given you some useful insights and sensible suggestions. Constructing a sauna isn’t simple, however the finish result’s completely value it.
Don’t Wish to Construct?
If my expertise deterred you from wanting to construct one (wouldn’t blame you for that), I’ve additionally tried quite a lot of different sorts of saunas over time. These have included numerous sizes of transportable, pre-made, indoor saunas, and build-from-kit saunas. A few of these embody wooden burning saunas, whereas others are transportable, private saunas (like a blanket).
These are those I’ve tried and would advocate:
Do you utilize a sauna? Is that this one thing you’d wish to strive or incorporate extra into your well being routine? Depart a remark and let me know!
