WHAT PEOPLE ARE SAYING…
“This was the best weekend. I learned so much and left feeling full of inspiration and conviction. We can do this y’all- the revolution is happening! I am so grateful to you, Rob and Scarlet, for working so hard to put together such a clear and digestible roadmap for all of us. And I am so grateful for having four days with the loveliest people to talk sauna. What a dream.” —Erin, NC
“What an amazing weekend of sauna immersion. It was something special to be in an intimate group of like-minded folk focused on something that brings us such joy. Rob and Scarlet so well prepared and so packed with knowledge and hands-on experience! I was so impressed with the smooth and thoughtful delivery of information. Possibly the biggest take away I got was that there are many right and not so right ways to do things, in the end sauna building is an art as much as it is a science, which is why my sauna is so authentic in the experience.” —Mark, MA
Rob and Scarlet are the real deal! I’m a professional carpenter and builder. I bought and adapted Rob’s mobile sauna plans, and I also did a consult with him. Two years later, and I’ve just had the pleasure of spending 4 days in the shop with Rob, Scarlet, and about a dozen other students, drinking from the firehose of knowledge and experience. They make a great team, both as builders and educators, and they’re just great people to be around. I couldn’t be more pleased and impressed with the experience, and I’m eager to get back to building saunas back on the west coast with my business, Sauna Väki. —Josiah, OR
Traveling with one of our mobile saunas to the lake and delivering to new owners.
We have been building mobile saunas for the past 10 years! and because of their growing popularity and versatility, they now make up most of our business. Each unit is still handcrafted with many layers of details. The owners each get a unique product tailored to their specifications. It’s also an easy way to avoid zoning and permitting restrictions while avoiding the hassles of a site-built project. Investing in your dream sauna makes more sense if you know you can take it with you!
We hear from our customers all the time that their friends, family, and neighbors are as excited as they are to have a sauna!

We offer building plans for DIY sauna builders or your local builder for one-time usage only. Thanks to our valued sauna plan customers, and the growing popularity of DIY sauna building, we have taken the opportunity to launch our new & improved mobile sauna building plans! Our sauna plans are 50+ pages and include detailed notes, drawings, photos, and material lists for a wood-fired 5’x8’/6.5’x10′. If you are thinking about purchasing our plans or building a sauna, we offer you an opportunity to build your own sauna using construction plans. Rob Licht has developed the best practices of sauna building with 30+ years of experience.
When we think of Sauna, we generally think of a wood-lined room heated by an electric or wood-fired kiuas (even though my last post was on the discovery of an old smooth plastered sauna.) The wood is integral to the experience—for the aesthetics of its look, its pleasant smell, and ability to take the humidity and temperature extremes. But all wood is not alike, and the question of what kind of wood to use always arises. The answer to that question, like everything else these days, is changing.
Typically in the US, especially in the generic gym and hotel saunas, and home kit saunas, Western Red Cedar is used. As its name implies, it is from the western US and Canada. All lumber is graded and each board is stamped as it runs through the mill. The grade indicates species, appearance, mill, and strength of the wood. The letters A-D are modified by Select, Clear and STK (select tight knots). For cedar saunas, it will be either a clear select grade or STK, the latter being almost half the price of the former. Cedar is also produced mainly for exterior siding applications and comes with a textured surface on one side that, unlike the sawing pattern of rough sawn lumber, is applied in the mill after sawing. This rough surface is considered the “good” side to which the grade applies. A big frustration with cedar is that I want the smooth side facing out and, since the board is graded to the other side, there is no guarantee that the smooth side has the appearance that the grade indicates.
Western Red Cedar, graded clear select with many variations of color
Color in cedar varies a lot: one side can be red and the other have annoying stripes of white wood. Clear select grade A boards will be better, but they come at a premium price, currently about $12-15 a board foot (12’x1 ft x1” thick, nominal dimensions). For years I have typically used Western Red STK for the walls and maybe Clear Select grade on the benches. This wood comes from either Idaho or British Columbia (BC). STK is likely from managed (regenerated) forest plantations and Clear Select is from larger old growth trees in BC. There is a guilt factor here I consider, so I veer towards STK whenever possible. (I also use Northern White Cedar frequently in freestanding saunas and our mobile saunas but that is the topic of another post.)
Cedar has been touted for its stability in the heat—which is true, and because of its low density, it doesn’t get hot to the touch—an important feature in a hot room with bare flesh touching the walls and benches.
Wood is a global commodity affected by the stock markets, inflation, building trends, shipping woes, fire seasons and the whims of political leaders who set tariffs as a way to taunt each other. You can make a career (and people do) out of studying the ebb and flow of lumber supply and prices. Add to this mix the pandemic and you have a roller coaster of unpredictability. The information I gleaned from building ten or twenty years ago I can no longer rely on. Suppliers have come and gone, quality has gone down and prices go mostly up.
The Pandemic created a real change in the labor force as well. There was never a shortage of raw lumber-logs but as workers and truck drivers got sick or just quit, mills shut down and logs piled up. The calculus used to predict building trends was skewed by everyone staying home and building decks with their pandemic relief money and we all saw prices soar while availability of lumber, especially cedar, shrank. In the meantime, the cedar I could get has been showing up with major defects, some from the mill, some from very poor handing: fork lift stabs are so common I have to over-order for very job. I assume this is the result of experienced older workers leaving the work force and being replaced by a cohort too inexperience to understand that the 6-board bundle they just mangled cost me more than what they make in two days. Some days I feel like all I make is very expensive kindling.
Cedar, graded side up (rough) with shipping damage
The truth is, in Finland, the source of my sauna inspiration, they don’t even have Western Red Cedar. They have soft wood species similar to what we have—spruce, pine, fir (SPF) but, in general, the quality and nature of wood varies by region. Wood from northern climates grows slower and has a denser grain.
As in Scandinavia, trees in uniformly dense forests have straighter grain as the trees race to reach up for the sun. Compare a “lone wolf” white oak, with its sprawling branches, to a deep forest oak.
Norway Spruce is the wood choice for many Finns, as are Alder and Aspen, which are soft hardwoods. The latter grow bigger there than our typical Aspen and Alder which rarely found at local mills. Cedar has been touted for its stability in the heat—because of its low density, it doesn’t get hot to the touch. But now Scandinavians have started using a thermal process of using heat and steam to modify wood and make it more stable and rot resistant (or so the web pages claim). I suspect there is also a Scandinavian work ethic at play: working in the trades there does not carry the same stigma of being a high school dropout, as it does here, and attention to detail and quality are paramount. Call it the IKEA effect.
Thermory and Lunawood are two brands available now in the US. The shipping crisis (highlighted by a boat getting stuck sidewise in the Suez Canal) has calmed down so now the economy of having quality wood freighted in containers from the Baltic’s to you (via a US distributor) probably makes more sense than wasting your time perusing the aisles of a big box store (or several) to glean out a few good cedar boards from a pile of fork lift-stabbed firewood. I also measure the time I spend trying to hide defects as I install the wood. While I still want to get all of my materials as locally sourced as possible, we are now in a global economy and looking abroad is certainly starting to make more sense to me. —Rob

If the heart of the sauna is the kiuas, or sauna heater, then the soul is the rocks.
—Rob Licht
Every brand of heater I’ve installed has a different approach to the rocks. Some, like a wall hanging 6 or 8 kilowatt unit, use less- maybe 40 pounds, and some, like the Harvia Cilindro or Club heaters use more— up to 200 pounds. Wood burners vary too, Kuuma’s heater takes 150 pounds or so, but you have to provide your own. My own custom built stoves ( Lämpimämpi ) take a similar amount and like the Kuuma stove, the rocks are piled on top, mounded as high as you can. The Harvia Legend, an elegant wood burner from Finland, basically has a cage that surrounds the stove. By the time you are finished loading it, you won’t see the stove. There is even an optional cage that surrounds the stove-pipe to hold even more rocks.
The Finnish and Swedish heaters use Olivine Diabase or Peridotite, igneous rock found in Scandinavia. All of the rocks I have used that come with the electric heaters look the same: grayish chunks, some flatter, some chunky, all in the size range you’d find in a bag of potatoes. These are amazingly cheap considering that they come all the way from some quarry in Finland or Sweden. The UPS driver has stopped asking what is in the boxes (“yup, rocks”). Once I found a note in one from a young Swede hoping that I was happy with my rocks.
My favorite rocks are hand selected glacial erratics: various igneous granitic and metamorphic stones that I find in places where glacial melt-waters sluiced out potato sized rocks. (shown below) These are heavier and denser than our native shale, which is worthless for the sauna since it tends to explode when heated. They have a crystalline structure that you can usually see and a solidity and heft that is evident when you pick them and bang them together (they are not easy to chip.)

A big consideration when selecting a heater is the rock capacity. The more rocks, the longer you should let your sauna heat up. Clients always ask:” how long should we let it heat up?” While I usually say “about 45 minutes” I really want to answer with the same sort of retort I give when someone asks how long will take for paint to dry (as long as it takes). The correct answer should always be: the sauna is ready when the rocks are hot enough to produce good löyly or steam—löyly is the soul of the sauna’s mysterious expression. And how hot is that? 450° Fahrenheit, more or less. If you want more steam, then you want more rocks.
Löyly is the soul of the sauna’s mysterious expression.

If you expect several rounds or people coming and going, then more rocks are good. No one wants to pour water on the rocks expecting a stimulating burst of steam (but not too sharp) only to hear the fizzle of water barely boiling. That’s like trying to make an omelet in a pan that is barely hot. Disappointing, to say the least, but also bad for the heater. There’s Finnish saying that goes something like this: when you leave the sauna put another log on for the sauna elf or he will pee on your stove. Which means, don’t keep throwing water on the stove, especially at the end, if the rocks are not hot. The warm water will just sit on the steel stove and rust it. When you throw water on the rocks, it should all turn to steam and when you are done, the stove should dry quickly. When I finish eating my omelet, I rinse my cast iron skillet and let it dry over the flame, I don’t let it languish all wet in the dish rack; same principle applies to the sauna stove.
Jagged rocks will catch and momentarily hold more water, allowing less to get past the rocks and into the heater. The dense roundish rocks I use produce a nice soft steam but they have to be hot. I’m not so worried about water getting down to my stove, which is always very hot (and mine have 3/8” steel plate on top so they will never rust out). By the way, always use clean water and be wary of city water with chlorine or even country water with minerals or methane. We use only use filtered water for löyly at home. Spring water or distilled water might be prudent in some cases. Never use pool water or worse, let some disrespecting novice wring out their bathing suit over the rocks, as I have seen happen in a gym. Pleasant smells should emanate from the rocks. Special sauna oils or even Sauna Brew can be added to the löyly water for aromatic effect. Heck, we used to add beer to the water (cheap lager was always best).
Custom Sauna with Harvia Cilindro with carefully placed olivine rocks.
If your electric heater comes with the grey jagged olivine rocks, I suggest using them. They are selected to fit between and around the elements. When setting the stones first I rinse them, then I take care to arrange the rocks one by one. It can take me 45 minutes to fill a large capacity heater. For the Cilindro, I place large rocks at the bottom to hold up the others and then work a flattish layer against the cage wall. I then backfill the rocks against the elements with smaller and irregular rocks. On the smaller wall-mounted units I try to fit the flat stones between the elements without forcing or bending them. The goal is loosely fill the cage so there is good airflow and to completely conceal the elements. Lastly, I top off the heater with larger stones and try to arrange them so they will catch water and force it inward, not splashing it out. In Finland there might a “spirit stone” placed here: a special stone or stones from a favorite place (make sure it is igneous or metamorphic—test it in a campfire first if not sure). The top might even have a layer of more decorative stones, which in Finland you can buy from sauna dealers, but here in the US, I have only seem the same dull grey stones. The Harvia web page has a good section on stones and how to place them into the pillar.
Once you have the sauna going and have been using it for a year or so, expect the stones to settle and flake off. You should remove them, vacuum out the heater and replace the rocks loosely, discarding the broken ones and adding more if needed. Failure to do so will cause the heater to eventually overheat and lead to the elements failing.
Care in selecting and placing the rocks will ensure that your sauna…. Rocks!
Wood-Fired Mobile Sauna by Rob Licht Custom Saunas.
Although Glamping is a term that was coined in the early 2000’s, the concept of an adventure in nature bolstered by all of the modern conveniences one could muster, or have mustered for them, has been around for well over a century and a half. In 1869, writer William H.H. Murray of Boston, extolled on the virtues of experiencing the Adirondack backwoods in his book Adventures in the Wilderness. This inspired an avalanche of urban neophytes to flock to the woods in search of adventure and commune with nature. These were known as “Murray’s fools”.
People traveled great distances and endured great hardships such as days of travel over log roads (which were literally made of logs placed side by side) to get to the heart of the Adirondacks. Once they arrived, they sought out the services of guides who did everything for them—transporting them in their guide boats, making camp, catching and cooking their meals. In essence, these early Glampers brought with them from the city every expectation of service they would get at the finest hotel.
“The mountains call you, and the vales: The woods, the streams, and each ambrosial breeze that fans the ever-undulating sky.”
—Armstrong, Art of Preserving Health
Glamping experience enhanced with a sauna (banya) in tow.
While part of me chuckles at the concept of Glamping with it’s pretense of tender-footedness, part of me is drawn to concept of rustic luxury. Although I am as far from a camping neophyte as one can be, with years of deep woods experience and many a night sleeping on hard ground, the concept of luxury camping does have certain appeal to me now. I’ll sleep in a tent on a platform—with lights and heat and maybe a commode. But better yet, with a sauna.
The idea of communing with nature combined with sauna is perfection—and something, I bet, even the luckiest of Murray’s fools never had.
