How to build a Sauna (Finnish Style) + Cost to Build

[@beermansf9791]

So far your the only guy on You Tube that has built a Sauna correctly , everyone uses the bubble wrap barrier .

[@simpsonpropertiesltd]

Thanks for feedback and support! It's much apprectiated.

[@tysonogloff]

Cedar is not recommended. Mechanical ventilation (ideally, low, opposite corner from the heater, under the low bench) is highly recommended. Having the air intake on the ceiling above the stove is recommended. Read Trumpkin's notes!

[@blackhouse7646]

Do you recommend the same book to build an outside sauna?

[@OddTinkering]

Great work! Seems very professional to me as a Finn. Just in case someone is interested in building their own sauna happens to read this, as a constructive critique based on my own experiences of using lots of good and bad saunas I'll add: The heater is definitely a little bit small, even with better insulation on the 4th wall I would've chosen a more powerful heater maybe even a 6kW model and I would've added a wooden flooring that allows the water to drain on top of the tiles. It would be less slippery when you step down from the bench. Sometimes you can feel a bit dizzy if you are there for too long and in that case you don want to step down on a slippery surface and the step is quite high so it's maybe a bit risky solution. You don't want to fall into the heater if you slip. Also based on the photos and the fact the room is 7 ft tall I'd place the highest bench a bit higher, you don't want there to be a lot of empty room above you, because that where the heat will be and to me it looks like there's plenty of head space still left even for a relatively tall person (maybe not for Michael Jordan though). If possible you want that step to be on the same level or above of the rocks on the heater with this type of heater so even your feet will be warm. Rising the bench and the step would also give opportunity to add one more step before the floor which makes it easier to get down and reduces risk of falling. Lastly I'll add that the door could be a bit lower. Especially if you come and go a lot and not just go in and out once during the session lower door will reduce the amount of heat that will escape because there will be a larger pocket of hot air above the door that won't escape when you open the door. But these are also things that affect the appearance of the sauna and it's a place you go to relax so it also should be built that in mind and sometimes that means sacrificing a bit of practicality for certain visual aspect and there's nothing wrong with that as long as it helps you relax. And an additional tip: you can also pour a drop or two of the essential oils to the water you throw on the rocks , that will prevent if from burning.

[@simpsonpropertiesltd]

I appreciate the constructive criticism. You bring up some great points for people to consider on their builds.

[@dialtone30019]

Thank you for these comments. I am looking into having a room extension to my house and wanted to add a sauna on an outside corner area. Also I'm considering using natural gas instead of electricity.

[@MachoMaster]

I agree, it was a well-built sauna! In addition to your excellent points, I will also add a few details: - Even if using the glass door, it's preferable to have/add/modify the handle to be made of wood. For aesthetics and safety (so it wouldn't heat too much). - Like you said, your feet should be higher than the rocks of the heater even when just sitting. Additionally, I highly recommend building a wooden safety rail between the sitter and a heater to raise and keep your legs in there. In addition to increased safety, the rail will significantly improve the efficiency of the sauna experience (the main idea of which is to get your whole body hot - inside and out; this process is way less efficient if only half of your body is being heated up and the other half is not only not warming up, but is actively giving the heat away, especially because the soils/palms are where the heat/coldness is directly going into or escaping from the core of your body; if you are hot, put your palms in cold water for 3 minutes and you will see how efficiently it will chill you). The wooden rail should be at an angle and have smooth/rounded edges, so it is comfortable to keep your feet there and soils wouldn't hurt. - I suggest smoothing the outside edge of the bench as well. From video it seems to be quite sharp, especially for kids to slide from it. - I also recommend installing the wooden rail in front of the heater. In addition to heater/people safety (keeping people away from the hot heater, and stop people falling into it) it will allow grabbing it in case of a fall; and to use as convenient helper when getting up or down the stairs. - I also recommend adding wooden flooring with gaps to the walking areas (so no need to put it under the bench or heater). They can even be removable Great job with the sauna! Making proper water drainage (with a significant angle!!!) and the air circulation makes your sauna better than the vast majority of other American saunas (even in very expensive places). The rest of my suggestions can be ignored, but I do highly recommend adding the rails. They will complete your sauna setup, both in terms of safety and in terms of efficiency of getting your whole body heated.

Comments were scathing about him missing those as everyone figured it would just eat itself in a matter of years. I'm either going to build one of these in my garage or increase size of my patio and put it out there. Thanks for the book recommendation... and the build out looks terrific!

[@sevenspineiii7524]

If your putting it in the basement and dont want to break out a bunch of concrete to reach your plumbing. Just install a dry pit and fill with gravel. The little water that drains into the pit will leach into the soil eventually.

[@martinr2962]

Thanks for the video - many useful information for anyone planning his own sauna! I have just finished my sauna, and as already mentioned I would highly recommend a stronger heater. I asked some local sauna makers in my area and all of them had the same calculation: 1kW per 1 cubic metre (35 cubic feet) and additionally 1kW per 1 square metre (about 10.5 sq.ft) of glass. I have 9 cubic metres of sauna with 3 sq.metres of glass. My heater with 9kW and 2kW for the vaporizer takes 1 hour for 90°C, but another 90 min. to get the whole sauna hot for real sauna experience.

[@simpsonpropertiesltd]

Thanks for sharing your insights and experience with your sauna build! I’m sure it will help others on their projects.

[@TheoSmith249]

1 square meter of glass, adds ~1 cubic meter of interior space. This needs to be calculated into your computational calcs for your heater. Always slightly upsize your heater and throttle down if needed. Nice build. !!

[@simpsonpropertiesltd]

Thanks for sharing that calculation. Great tip 💡

[@improbus100]

That is a good looking sauna! And it's great to see that you have put thought into this and know what you're doing. Don't ever underestimate the importance of drainage and ventilation. They are vital when building a sauna. Otherwise you'll end up with water damage and it'll cost you lots of money to fix. Cheers from Finland!

The floordrain is a must have thing. You still need to clean the sauna every now and then.

Overall, well built. A few key things could have used some improvising, but well built! For the safety of the users we do not install all metal handles on the interior of the sauna. Stitched leather wrapped around the metal is a great way to reduce the handle temperature, especially with the handle being close to the heater. Kind Regards!

I have a question, I have followed ur lead on how to build the sauna and I believe I have done a decent job following ur lead! In that note what did you treat the cedar wood with or have you treated the wood at all? Thnx again.

[@simpsonpropertiesltd]

I did not treat the wood. I kept it natural and the cedar is holding up really well. It’s not like exterior cladding where it would be exposed to the elements. In this case I wouldn’t want to breathe in any off gassing from a sealer either.

[@Ahmed22j]

Great build 👍 Can you advise on the type of wire you used for sauna connections? Did you use a romex wire inside non metallic conduit to protect from sauna heat ? Thanks in advance

[@simpsonpropertiesltd]

Thanks! I used romex NMD90 from the sauna controller to the heater junction box. I installed a piece of rigid conduit from the wall device box to the heater. The area the wire is terminated in is below the heater. Temperatures there remain relatively low. To be extra safe you can install BX wire (armored cable) if you want.

[@eloisecamire3741]

I really love how you made the ceiling and side walls waterfall and the bench and backwall horizontal, really modern and clean. With the full glass front it's just the nicest pattern I have seen so far. I noticed you don't have any trims and it helps with the clean minimalist look as well . Did you leave any gap for expension/compression or it's not an issue with indoor sauna? Maybe we could do ceiling first, then the back wall leaving a small gap on both sides, and then the side walls? What do you thin? :)

[@simpsonpropertiesltd]

Thanks! I am really happy with the final product and the layout. I did leave a bit of a gap between the cedar and the tile floor. I kept the joints as tight as I could in the corners. No matter what over time there will be some expansion and contraction in the corners. So there are so tiny gaps between some boards in the corners. A clean way to conceal that is using a piece of flat stock cedar and fasten it in the corners. You could do the ceiling first, back wall, front wall, then side walls. If I were to do it again that would be the best way to have to corners with no trim needed.

Great video, thanks for sharing the useful tips. Question regarding rockwool insulation - did is smell when you opened and installed the batts? If yes, did it off-gas for some time and then stopped? The rockwool states they use 3% of formaldehyde in the foam and probably I'm over-focusing on the smell, but just want to check if you had similar experience or if I just got a bad batch of the insulation.

[@simpsonpropertiesltd]

Thanks! I have never had an issue with odd smells/off gassing with Rockwool products. The only issue I have had is one supplier stores the bags outside. When I opened the bags on site a lot of the batts were wet. They took days to dry out.

[@jakec5618]

What's your thoughts on building one or purchasing pre-built saunas ?

[@simpsonpropertiesltd]

It all comes down to your budget and the level of finish you’re trying to achieve. It will most likely be more cost effective to buy a pre-built. Anytime you add “custom” to a project it usually costs more and has a higher end finish.

What strip lighting did you use and how did you plug it in? Did you plug it in outside of the sauna or did you just have an outlet under the benches?

[@simpsonpropertiesltd]

Thanks! It’s low voltage tape lights. They require a small transformer to step the voltage down. You can buy them from most electrical suppliers or Amazon. I hid the transformer in the ceiling cavity and fed it off the same power source as the pot light in the sauna. Then I ran the low voltage two conductor wire from the transformer to the track for the tape lights. Best of luck on your build.

Question about the strapping... if i'm doing horizontal instead of vertical cedar on the side walls, would you still be able to do the strapping? If the strapping is just attached vertically to the framing studs it doesn't seem like it would give the same benefit of letting the cedar breath.

[@simpsonpropertiesltd]

If your strapping is installed vertically it will still create an air gap between the cedar and vapor barrier. Allowing your cedar to last longer vs installing it without strapping.

[@simpsonpropertiesltd]

For the type of sauna in this video (electric heater) you can vent the sauna inside the home. I had the intake and exhaust located in the water closet beside the sauna. That way the Aria vents are in an area that is not as visible. In your situation you can install the exhaust into your bathroom. Try to be strategic with it so the venting looks clean. I personally like Aria vents. They are made locally in Toronto but I’m sure you can order them online and have them shipped.

I have no idea if that foil back insulation would serve as a double purpose. I personally would not use it. I think it would be a tedious installation process.

Very detailed and helpful sauna build. Well done. What did you use for the light channel, where you inserted the LED strip?

[@simpsonpropertiesltd]

Thanks! It’s called an LED tape light track & diffuser. It’s a metal channel that the tape lights sit in. The diffuser clips into the metal track and distributes the light evenly. You can buy them online or at most electrical suppliers.

What prefab company sauna would you recommend in the US..any tips what I should look out for

[@simpsonpropertiesltd]

The company I bought my heater from makes prefab heaters. They are based in Toronto though & shipping may be expensive. Here is a link to their site: saunacore.com/ There is good info on their website on what to look for in prefab saunas. Sorry, I am not aware of any US companies.

I'm in the middle of building a custom basement sauna and have a question about ventilation hoping to get some feedback from those with experience - the adjacent room is a 7'x7' bedroom closet and the other side is a large rec. room, can I exhaust into the bedroom closet or is there a concern of too much humidity being pumped into such a small space? Also, should I close off this vent during use then open it once I'm done? I'm assuming you would want to keep the heat in as much as possible while you use it. Lastly, for the intake, rather than a vent I'm planning on keeping the door 1/2" above the floor which is also where the heater will be located - would this suffice?

[@simpsonpropertiesltd]

1) That’s a good size closet but I wouldn’t recommend venting the sauna into the closet. If possible run your venting through the closet, build a bulk head around it and vent into the room adjacent to the closet. 2) I keep the vent below the heater and the exhaust vent fully open at all times. 3) I have a ½” gap below the door and an intake below the heater. I would recommend you still install a intake vent below the heater.

I have an existing 1-person FIR sauna (radiant health e1h), and would like to remove the glass door (65"H x 24"W) and position a Red-Led panel in it's place (36"Hx12"W). Mounting the panel on a movable tv stand is not a problem, but once I wheel it into position, I don't want any gaps between the panel and the door-jamb. I understand the existing "Serious-Window" glass door is triple-plane (R6?), but I was thinking I could mount some insulating material (spaceloft-aerogel , XPS, HempWool, etc) around the panel? Since it's such a small area , the cost of the insulating material is not a concern, nor it being fire-retardant. The only concern would be breathing right next to it. Any suggestions on mounting or what I can do around the panel to insulate it?

[@simpsonpropertiesltd]

That’s a tough one. I think building a custom panel/door with insulation inside the frame would be your best approach.

[@amystead9850]

This is good info! How would you have vented it if two of the Sauna walls were exterior walls?

Thanks! I would place the intake & exhaust vents on the front wall. You have no other choice. You could install the exhaust vent on the ceiling in the adjacent room as well. Which ever will look better.

Great Video! I had a question: If I'm doing this in my basement, against exterior walls (2 of the 4) however those are already have your basic pink r-15 insulation, should I remove that insulation and replace it with the wool insulation / reflective vapor barrier for those walls in particular? I assume I cant just use put another layer of insulation without creating a "mold sandwich"., thus the approach would be to remove the poly, add the rockwool, and then for that portion add the reflective vapor barrier? Any help would be greatly appreciated!

[@simpsonpropertiesltd]

Thanks! That is exactly how I would address insulating those two walls. You would not want to have a double vapor barrier and risk the potential of condensation forming in your sauna wall cavity.

Great job but can't help thinking that the cedar will buckle with expansion/contraction as all the joints seem to be cut precise with no gap and beading?

No issues at all in regards to expansion/contraction. It’s tongue and groove cedar and designed for tight tolerances. The only area where gaps can form is the corners which can be covered with trim or corner round.

Did you wire the sauna heater using a NM-B or THHN/THWN wire? I'm trying to read upon the best practices and I'm not sure if a sauna would be considered a "damp" or "wet" location, assuming its a dry-sauna with the occasional water poured over the rocks?

[@simpsonpropertiesltd]

I used NMD90. I had conduit from the wall plate to the heater junction box. None of the wire is exposed. In my situation it is not considered a wet location.

[@christophergabba5431]

Thanks for the awesome video! I’m curious what the best source of cedar is? Did you buy it from a local store or did you find it online somewhere and order it? It appears to be very expensive..

[@simpsonpropertiesltd]

Thanks for watching! Tongue & groove cedar is an expensive wood. I would avoid buying it from big box stores. They mark up the costs substantially. It’s best to shop around at your local lumber suppliers & see who offers the best price per linear foot.

I ran the power feed from a light switch to the pot light. I hid the low voltage transformer in the sauna ceiling. It’s accessible by removing the pot light. From there I ran my low voltage wires to the benches for the tape lights.

@@simpsonpropertiesltd Interesting! I'm going to have the ceiling lights connected to my Sauna control panel so they are independent of the LED bench lights.

So thats where I'm trying to figure out where to put the transformer since it won't be tied to the overhead lights, but still have it accessible.

@@amystead9850 you can still hide the power supply in the ceiling cavity if you use a pot light. I use the bench lights only and keep the pot light unplugged. Your other option is to build an access panel in a wall under a bench to access the low voltage transformer. You can use magnets 🧲 or a hinged door.

[@brycegoligher2399]

Hi there. Great video! I'm building a sauna in my home and I'm wondering if the tiles get too hot when used at 160 degrees and above? Also I'm leaning towards no floor drain as the trap will need to be primed in order for sewer gas not to come in the house. I don't think it will need to be cleaned that often. Also with no drain I can do a simpler flat floor. Thoguhts?

[@simpsonpropertiesltd]

Hi, surprisingly the tiles don’t get hot at all. Anywhere below the first bench remains relatively cool. You’re right the drain would have to be primed. I find once a week it needs to be cleaned. Mainly due to pouring water over the sauna rocks. The rocks leave a bit of a residue. Like I said it’s not make or break if you have a floor drain BUT it’s nice to have. With no floor drain there would be no need to slope the floor.

[@innovativesaunascellarsinc7125]

Typically at the floor elevation you will not find much of a heat difference, as heat rises. In fact, for our custom infrared saunas we install heated floors for our customers that enjoy doing hot yoga or simple exercises on the floor. It also reduces the warming time ever so slightly, but helps maintain a comfortable heat throughout the sauna. With the heated floors we do not install drains. No floor drain is okay as well. When pouring water over the rocks you should always wait at least 15 minutes ( heater depending ) until the rocks have become hot enough to evaporate the water. Never pour water over a cold heater, of course.

[@larsstrong3426]

Hi! I was told LEDs would not work in a sauna (185F). What are your thoughts? Thanks!

[@simpsonpropertiesltd]

I have had no issues with my led tape lights at all. They are installed inside an aluminum track and have a diffuser installed (cover). I installed mine below the benches. Surprisingly, it does not get that hot in those areas. The majority of the heat rises to the upper pocket of the sauna above the second bench.

[@zoltankis7380]

Great video, thanks for sharing! Did you find any issue with the air gap between the glass panels? Don't they let out a considerable amount of hot air into the bathroom? Or is it negligible compared to the heat loss at the big glass surfaces? Thanks!

[@simpsonpropertiesltd]

Thanks! The small gap on the bottom and sides is negligible. The small gap on the bottom is a good thing because it allows fresh air in. There was a larger gap on the top of the door that was an issue in regards to heat loss. I got my glass installer to insert a black metal filler piece to retain the heat. The original plastic guard didn’t hold up well due to the high temperature.

Did you use a stain on the cedar? Maybe its just the light but it looks like western red cedar with maybe a stain applied?

Porcelain tiles are usually more durable and better quality compared to ceramic tiles. I would recommend going with porcelain. Not that much water accumulates. Just be prepared to clean the floor after 1-3 uses. When you pour water over the stones you get a residue that is left on the tile floor.

Hey Ken, you won’t like my answer. I avoid discussing costs because it can vary so much demand in where you’re located, material & labour costs etc. You have to do your own home work. Reach out to a few local contractors and get estimates. If I throw out a random number it’s not going to help you.
