I want my own sauna, where do I start?

Saunatimes.com.

I get a lot of emails, folks thanking me for saunatimes.com.  This warms my heart.  One day I may do the affiliate marketing gig, and one day soon you’ll see some of my sauna related products/inventions off to the right hand side of this page.  Yet for now, here it is, free relevant sauna information.  For we are kindred spirits.  We recognize the health & wellness benefits to sauna.  We recognize the importance of having our own authentic escape vs. a light bulb infrared closet or a hot tub petri dish.

Lots of noise out there.

“The other sites I’ve come across are mostly trying to promote their kits, without much useful info.”  He’s right.  And everyone has their self interest.  Mine is to diffuse the noise and be straight with you.  Compounding the noise is the fact that ‘sauna’ is becoming a bigger story. So people are getting in the game.  Infrared hucksters are packaging high margin kits and are working hard to try to sell them to you.  So, here you are, reading this with a keen interest in cutting through the noise in an effort to getting your own authentic sauna.  Welcome.

So, where do I start?

I’ll make this easy: inside or outside?  Not sure?  You are on a hike in the woods and you approach a fork.  To the left is a more used trail, easier in navigation, looks to be less work.  To the right is a less used trail, thicker trees, somewhat more rugged.  Pick a trail, and I’ll walk with you.

  • LEFT TURN: You chose a sauna heated by an electric stove, most likely in your house.  You can carve out about a 6′x6′ space, maybe in your basement, maybe convert a closet, maybe go to town and incorporate a sauna as part of your bathroom remodel.
  • RIGHT TURN: You chose a sauna heated by a wood stove, very likely outside your house or cabin.  My 8′ x 12′ design is a great starting point, and in most cases will be your ending point as many have adopted this design and nobody that I know of has regretted anything about it.

OK, I know my sauna turn, now what?

CAVEAT:  I’m a right turn guy.  I understand the realities if you chose left turn, and I don’t begrudge your decision.  You deserve your own sauna.  Nice job so far.  If you chose an electric sauna in your house, get a piece of chalk and mark off your space, we’ll come back to you later.  If you chose a wood burning sauna, find 4 sticks and 50′ of carpenter’s string, and let’s mark off an 8′x12′ spot on your property.  Keep in mind:

  • Slope: If your spot has slope, you’ll most likely want your sauna building so that the 8′ run is into the hill, the 12′ run along the slope of the hill.
  • Exposure: Very important.  Imagine your 8′ x 12′ sauna at different times of the day, relative to sunrise, sunset, etc.  Ideally, I like the 12′ wall with exterior door facing South, but East or West can work just as well – it depends, of course, upon:
  • View: Your most critical consideration.  You want the door of your sauna to spill out in a direction that makes most sense, relative to your property.  This is obvious stuff, but the fun thing is after you mark off your 8′ x 12′ sauna/changing room, you can mock up a door, and then think patio, fire pit, a little lawn furniture, and if you need an outdoor shower.

This is how you get started.

Wood or Electric sauna stove?

I have had many emails on this question.

  • “I’m building a sauna and can’t decide whether….”
  • “Glenn, you mention an outdoor wood burning sauna but we have an ideal place in our basement for….”
  • “My husband wants a wood burning sauna, but i’m worried about…”
  • “I grew up with an old school wood burning sauna, and now it’s my turn to build my own….”
  • “Glenn, I have plenty of access to wood, and enjoy the wood cutting experience, yet I’m concerned that my wife won’t want…”
  • “What about the smoke, will my neighbors…”
  • “I’ve heard that a wood stove can take hours….”
  • “I can hook up 220v heater because we finally pulled out our hot tub bacteria petri dish…”

In defense of electric heated sauna stoves:

  1. Easy to use: Flip a switch, or use the programming device.
  2. Easier to install, no chimney stack.
  3. No red tape with insurance company or fidgety building inspector.
  4. Sauna stoves heat rocks, who cares how they’re heated?
  5. Cleaner, easier to maintain.

In defense of wood heated sauna stoves:

  1. Authentic, natural way to heat.
  2. Brings forward the ‘up north’ cabin vibe.
  3. Promotes and outdoor experience and the concept of escape.
  4. Negative ions are realized through wood burning.
  5. Wood burning saunas vent better, more naturally.
  6. More radiant heat for better “ahhhh” loyly production.

I didn’t list that electric sauna stoves heat quicker, as I can personally attest that my wood burning saunas (all three) heat up about the same time as electric sauna stoves.  Nate’s Firestarters help, custom made by a Barton School student.  They are so easy, an 11 year old can do it.

Wood, electric, let’s not debate forever:

NOW IS THE TIME FOR YOUR OWN SAUNA.


Are you ready for your own sauna?

At the Lake Home & Garden show in Minneapolis this weekend, there was a booth displaying infrared ‘saunas.’  I have strong opinions of these light bulb closets as they are:

  • cheaper than an authentic Finnish sauna.
  • look easier to install than an authentic Finnish sauna.
  • seemingly less work than an authentic Finnish sauna.

Yet we are smarter than this.  We understand that McDonalds can make things cheaper, easier, with less work.   And we also know there are lots of folks who will choose a McDonalds version of a sauna.

But we are not those people.

Imagine your favorite restaurant, one that loves the food they prepare.  One that has original items on the menu and has servers that are happy to be there, that look you in the eye and smile when they tell you about their specials.  And when the food comes, it tastes great and is good for you.  It affords great value and gives you an experience worth coming back for.

Are you ready for this experience?  Are you ready for your own authentic Finnish sauna?

I have one for you.

A great idea for your sauna floor

A word on building your own sauna and dealing with the sauna floor.

Here’s an email exchange that may offer some guidance:

Hi Glenn
The Saunatimes.com website has me a converted man…I no longer want an outdoor sauna, now I NEED one!
I live in Surrey, BC. Our winters are mild by Minnesota standards but the dampness and rain chill a person to the bone.
I have started to aquire the materials to build my outdoor sauna and have a few questions about the ideal outdoor sauna design.

1. The opposing bench design looks like a good idea on paper but I noticed your portable sauna has L-shape benches. Is there a change of “ideal”?
2. Flooring in the sauna and change area. Any recommendation on how to finish them or does bare plywood stand up alright?

Cheers
Dan

And my response:

Dan..

Wonderful email, and i’m glad to have helped and influenced you.  You ask two great questions:
1. “L” bench is the more ideal… yes, change in “ideal sauna” glad you caught it.
2. Plywood floor.  Yes, start with plywood as a subfloor, then:

  1. Paint it or treat plywood with a water sealant.
  2. In the hot room, I suggest screwing in a drip edge around your perimeter.  Your first row of t&g cedar can rest on that.  I rip a 2×3 green to get a 45 degree upper edge.
  3. cut and install a shower drain in center of hot room.
  4. get a couple bags of vinyl cement patch, 40# i believe. it’s cheap.
  5. mix that in a wheelbarrow.
  6. trowel it down in the hot room floor.
  7. 3/4″ around perimeter, down to about 1/4″ at the drain.

It’s a real slick system…. couple points to keep in mind..

  1. keep your bottom plate in tact where your door is, or sawzall it and screw it down so your cement has a place to stop.
  2. consider patio block where your woodburning stove will sit.  Lay that first, before cement.  trowel up to patio block.
  3. chalk line your drip edge before screwing it down to bottom plate, framing, as a trowel mark, guide.
  4. You don’t need much of a pitch if you’re sauna building is level.
  5. You’ll build cedar decking (1×4 cedar with 1/2″ spacing) on top of this.  this is where you’ll walk.  feet stay dry.

take pictures!  keep in touch.

Road testing your sauna in the cold

Sauna: test it in cold weather

It’s been really cold here in Minnesota.  Just like with car batteries, this is the kind of weather to really get to know your wood burning sauna stove in your outdoor sauna.  In normal weather, any old stove with any old type of wood can get any old sauna up to 140 f (60c).   With time and determination, a combination of decaying pine branches smoking along in some home made metal box stove in shoddy insulated sauna room will eventually provide enough BTU’s to offer a sweat and some form of sauna.

A more serious sauna environment

Here in Minnesota, we don’t mess around with heat.   We can’t afford to.  It’s been below zero (-20c).  It’s great sauna weather.  And no matter where you live, you shouldn’t mess around with a lame sauna stove, or bad wood, or a poorly designed sauna.  Doing it right doesn’t mean you have to spend a lot of money, either.  This is the type of weather where you can tell how good your sauna stove is working, or where there’s a crack in your sauna door and the difference between burning pine and oak.

First things first, your outdoor sauna

I’m a big fan of good basic insulation, and a bigger fan of foil vapor wrap. Batting is cheap.  You can frame with 2×4.  Keep your ceiling at 7′ and if you go with 8′ ceiling, that’s fine, go with 3 benches but keep you cube small.  It is a lot easier to heat a small room than a big room.  This isn’t a suburban game of sheet rock palace, square foot fever.  This is an example of less being more.

Second, know your wood

If you’re heating with an electric sauna stove, you can move on.  However, us wood burning purists like to know where our BTU’s come from.  We are like microbrewers and gardeners.  Some of us have beards.  We stutter when we say ‘sustainable’, and some of us mumble words like ‘renewable’ in our sleep.  Up north, I burn birch almost exclusively in my cabin sauna but here in Minneapolis, it’s all across the board.  When I hear a chainsaw, i’m like a dog who hears another dark barking.  I chase after the sound and newly felled wood.  Many are more than happy to part with their tree cuttings.  Stay well clear of Elm (ash bore) but here are my favorites:

  • Maple: dense hardwood.   Harder to light, but burns long and hot and slow.   Great to add to a hot fire.
  • Pine: Burns fast, produces more ash.  Great starting wood.
  • Oak:  My favorite all around burn.  Megga BTU’s, especially well aged red oak.
  • Birch:  Fantastic for saunas, burns hot and bright.  BONUS: birch bark is nature’s gasoline.

Third, get a real sauna stove

I’m biased.  I own three Kuuma wood burning sauna stoves. They are the best sauna stove made.  I can bring my backyard or cabin or mobile sauna from 0 degrees f. (-18c) to 130f (54c) in about half an hour with 3-4 good pieces of wood.  Then, after pulling the hot coals forward, I’ll add another stick or two, and bring the sauna to 150 degrees f. (65c) a few minutes after that.  I can manage the fire, manage the burn rate, and take a 2-3 hour three round sauna at around 170 degress f. (77c).  All that with an armful of well season firewood.  sussusstainable.

How do you road test your sauna?

The evolution of the mobile sauna

A letter to a kindred spirit in Alaska

Hi Eric.. As you know, I have 3 saunas and yes, my mobile sauna is for sale. It’s not like a car, everyone needs one, but more and more of us are understanding that a sauna has more benefits than a car. Those of us who “take the plunge” with our own backyard retreats are long tail enthusiasts – this is one of the reasons why I do saunatimes, so folks like us can connect.  Yoga, beer making, spinning.. all this stuff starts somewhere.

I want to sell the mobile sauna only because I am going to rebuild the same sauna design on it’s own chasis and wheels – call it the Mobile Sauna II.  Mobile Sauna I was built so that folks can experience what an 8′x12′ authentic sauna retreat is, and conceptualize it in their own backyard.  It’s a perfect design and i’m proud of it.  Mobile Sauna I deserves to be in someone’s backyard idling warmly on a cold Minnesota star filled night.  Mobile Sauna II will allow me to be at more places and events, able to tow it with a standard vehicle.  One day I just may show up in your Alaskan town with Mobile Sauna II warm and ready to go.

I’ll let you know, rally your townspeople!

Building sauna benches

There are a few different ways to build sauna benches, and here’s a play by play on my favorite.

Keep in mind:

  1. Hide the knots
  2. Hide your screws
  3. Make your benches 1/4″ less than your actual wall to wall dimensions.

Supplies:

  1. 2×4 cedar
  2. 1×3 cedar
  3. 2 1/2″ wood screws

Tools:

  1. table saw
  2. miter saw
  3. drill

Build your frames:  Cut your lengths and ends and screw them together to make a rectangle.  I like 18″ wide benches: two 2×4′s  + five 1×3′s + spacing = 18″.

build sauna bench frame

Cut and screw in a 1×3 inside the two frame ends so that when you set in your decking it will lay flush with your frame.

build sauna bench end nailer

Rip your cross members:   You’ll want to rip some 2×4′s down the middle, creating 1 1/2″ x 2 1/4″ stock.  This is optimal wood depth for your 2 1/2″ screws.  You will be screwing your decking from underneath.

build sauna bench rip cross members

Set your cross members:  Space out the cross members evenly.  Screw them into your frame recessed 3/4″ below your frame so, again, your decking will lay flush with your frame.

build sauna bench cross members

Lay out your decking:  I like to get a total picture of all my lumber stock so I can choose the best sides and best wood match.

build sauna bench lay out & measure boards

Cut your decking:  Measure from inside your frame to the other end.  Cut your 1×3 deck lengths.

build sauna bench cut to length

Screw your decking from below:  A little wood glue may help.

build sauna bench lengths

To set your upper benches,  screw into your wall a 2×4 header at 28 1/2″ from the floor all the way around your sauna where your upper benches go (note the location of your studs, screw through your t&g cedar and into the studs behind.. use 3″ or 3 1/2″ screws for this).  Set your upper bench on top of your header with a couple screws (you’ll be happy you made your benches 1/4″ less than your wall width).

For your lower benches, make a couple sets of legs 12 1/2″ tall.  Under the bottom of your bench feet, screw in rubber thingy’s so the wooden feet are not right on your sauna floor.  This prevents ”wicking” of moisture.  If you are from Jamaica, you can be resourceful and use beer caps for this (very irie how Jamaicans recycle used Red Stripe caps as washers for their corrugated iron fences).

Your lower benches will sit at 16″ (12 1/2″ + 3 1/2″) and your upper benches at 32″.

Andy:

I’ll email you separately regarding drip edge.  Great idea on the 2x space!  Glad you are open to reducing your hot room space.  keep in mind that every cubic foot in your hot room comes at a price: more cubic feet = more BTU’s required.  It’s been an ongoing study for me to maximize sauna hot room size, yet maintain consciousness to it’s BTU cost.  I believe that a 6′ x 7’5″ sauna hot room is ideal.  My Minneapolis sauna can handle 12 people.  http://www.saunatimes.com/2009/04/06/sauna-party-april-2nd-2009-minneapolis-mn-usa/.

Glad you’re moving forward,

All good ideas! I hear your concern with a 10x sauna room. Might use the 2x space for an outside/ inside loading depot for wood. As for the drainage that too sounds like a good idea. I’m not familiar with vinyl cement, though I assure you I’ll do the research. Love the locker idea. And yea I’ll bite, what is a drip edge?

Andy:
I think your hot room is too big.  10×6 is pretty big…could you go with 8×6 and use that 2×6 space for an outside feed tool closet?  have shed doors open to the outside, like a closet.  I have lost count with the number of saunas i’ve been in that have too big of a hot room, they remind me of those yucky cigarette boats, way too much power and inneficient function.
Changing room walls can be whatever you like.  My wife and I are scheming on a changing room with exposed studs, painted white or stained a burnt orange to look old school.   The joist cavities can serve as a great open locker, and frame in a couple 14 1/2″ shelves to hold a beer or two.  Number the locker/joist cavities.. could be slick!
Drainage in hot room:  I”m just finishing a sauna where I used 3 bags of vinyl cement patch kit (40#) from Home Depot.  Assuming your subfloor is level, mark a 1/2″ line along your wall and feather it down to a floor drain.  Then put down some cedar pallet on top of that.  It’s slick.  That product is easy to trowel.  Ask me about a drip edge if you wish.

I just procurred a 10×16 shed for our sauna.My plan was a 10x6x7 sauna room and a 10×10 changing room. Does the changing room wood need to be same as sauna (looking to save some money.) Also, would like to put drainage in sauna room. My thoughts were rubber 45 mil. membrane over existing plywood and drain somewhere in there? Any ideas??

A word on sauna vent (exhaust)

Glenn,
Do I have to vent (exhaust) the opposite side from the heater?  I am thinking about having a small gap on the bottom of the door (intake) and then having a vent on the upper end of the door for exhaust.  Something tells me that this is not a robust design.
Oh yah, my door and heater will be on the same side of the sauna.  Door will be centered and the heater will be in the corner.

Shane

Shane…

Good move on venting with a crack along the bottom of the door. it’s easy and functional.

As far as exhaust vent, the first thing to note is that an exhaust vent is really only to allow stale air to escape sauna, say, after a sauna session.  Some purists like to vent during a sauna, but if you are using wood heat, there is enough fresh air pull, just by wood combustion.

But an exhaust vent is a good idea.  You build a sauna once, so may as well put one in.  Your instincts are correct.  Put your vent opposite wall to your door, and I like about a foot from the ceiling.  They’re easy to install.  Drill or jig saw a 3 1/2″ hole in your wall sheeting.  You can buy a vent with the exterior grill already in.  Screw it to a stud and insulate around it.  When you do your t&g cedar, just cut around the round metal pipe.   I like to make a little vent control slot thingy using some t&g cedar, with a little wooden handle. I’ll try to take a picture for you sometime.  it deserves a post.

PS.. If you have already built a sauna without an exhaust vent, no worries, just open the door when you’re done.
