This heater is BY FAR the best value available. The instruction video is very detailed and the components are very high quality. This thing is a beast. And the heat it puts out is wonderfully hot.
Thanks Joe! Your plans were super easy to follow and we built our garage gym sauna in a weekend.
These plans were very detailed and the videos helped with the build. Joe was available to questions with a quick response. The saunas performance was as advertised. Thanks for a great product.
My husband and I have been thinking about a sauna for a while but just never found anything we loved. Then he found this! He loves building and the plans were easy to follow and any questions he had were quickly answered! Sauna time is already becoming the favorite part of my day!!
Great unit. Works fine so far. I wanted one specifically with 50ml/hr output since higher isn't needed, and the best deal for one was here. Appreciate the customer service with my follow-up questions. Definitely recommend.
I purchased the DIY Sauna Heater Kit in early November 2025. It has been the best thing I've bought in quite a while. I use it nearly every day.
Assembly and installation were very easy because of his instructions. Adding video to the PDF instructions were particularly helpful for any nuances.
The recommended lights were also helpful. I would not have known where to start even. The heat and infrared light makes me feel energized after every use.
I also used an EMF reader to see if there was any electro/magnetic frequencies coming from the kit. There was virtually no EMF's coming off of it. Contrast that with my computer which the EMF reader said to avoid when plugged in.
I would highly recommend to anyone who is a do it your self type person.
This thing is sick. Thorough instructions and great support. My only feedback would be to include a piece of the stainless steel mesh for safety as part of the heater kit. And that’s super minimal. I have no issues and love my Sauna!
Awesome instructions cpl things off but common sense says to measure anyways. When I say off I mean like 1/2” or so NOTHING major. Felt like I had the hang of it after halfway so I cut siding and of course I was off 🤣, nothing a little trim can’t fix. So follow instructions until the end! I built the standard and I’m 6’0” probably 12hrs build time total.
Hey Juan! Thanks for the review. Curious what was off, this was the first I've heard about this after a couple hundred builds. Glad you're happy with the plan - here to help
These are THE way to go! The bypass lever alone makes it worth the price for quick and easy filter changes.
I purchased the DY sauna kit and heater. Everything arrived as promised very quickly. Everything is very thorough and complete. I am partially through the build and it is nice to have such easy to read understandable instructions. I look forward to getting this done and using it consistently. Thank you so much.
This was a very well thought out plan. You can tell he took a lot of time with the measurements and everything. Everything was pretty much perfect. Even the heater was a really nice design. I recommend putting metal mesh on the bottom of the cage in the front of the cage, just in case the glass does shatter any glass particles may not fly at you or fall onto your feet other than that everything was literally amazing
Great ozone generator. Easy setup and works perfectly with a venturi. I struggled with keeping my plunge sanitized for months and this fixed all of that immediately. Highly recommended.
Awesome product! Straightforward plans, easy to follow, no BS. Will update when I actually build it.
I purchased the sauna plan after building a cold plunge last year. Both plans are very detailed, easy to follow, and include videos. So now I have both a sauna and a plunge for less than what others are selling one for. I have a great shop, but even without one this build can be easily
done with rudimentary tools and woodworking skills. The build is complete, waiting on the preorder heaters to ship.
I’m a hobbyist woodworker. Overall, I’m very happy with this build! I think it’s my most complex woodworking project to date. The materials list was great, the diagrams were clear, and the videos very helpful. Joe was quickly responsive when I emailed him with questions. I had a good time making this, and I’m impressed with the end-product. I’m proud that I built this, and I’m so excited for daily sauna sessions!
A couple things I would do different if I made this again: I would not use dimensional 2x4 and 2x6 fir lumber as it was thicker than the other framing wood that I bought, or I would plane it down to be the same thickness as the other wood. This caused my framing to bulge wherever it was used, and I didn’t realize it would be an issue until it was too late. This made fitting the siding to each panel difficult, and I wound up with some gaps and overhangs in some areas. I installed some trim to go along each edge to hide the imperfections at the seams. The jet black Varithane stain that Joe used wasn’t taking to my siding, so I had to buy black exterior paint instead.
Finding some of the materials was also a little difficult. Nobody had 5/4” cedar planks, and I drove all over to find decent 1x6 clear cedar, and it was pretty expensive at a specialty wood store. Finding the R15 value Rockwool at my Home Depot was pure luck… they don’t carry that anymore, but someone had recently returned one package, and there it was waiting for me.
I don’t think the materials list calls out a 1 ½” hole saw, so I had to go out and buy that right before I needed it. Not everyone has a nail gun, but luckily my friend let me borrow his.
My receipts came out to $1826.86, which is 50% more than the ~ $1200 stated, but I noticed items like the bulbs, cedar TNG, backrest, grommet cover, sauna oil, paint, and some misc supplies and tools were left out of his calculation. Plus things cost more in California. This still costs 1/3 of similar-style commercial infrared saunas. I would definitely recommend this project for someone who is good with tools and building stuff.
My friends are all asking me about my new sauna! It’s attention-getting for sure.
Great plans and instruction. Project went together very well and works better than advertised. I struggled cutting and attaching the outside panels and would probably use a router and panel cutter bit to get a better fit.
Amazing plans! I have completed Joes cold plunge plans and now have done the sauna!
Super clear plans with instructional videos… highly recommend
Built an XL for a buddy and then just built a standard for myself. I'm 5'10" 160lbs and the standard is perfect. See the pic - in 70 minutes the temp was up to 240 degrees. For my first time, I let it drop to 190 degrees jumped in 15 minutes it was 210 degrees. I love it. Instructions and videos are outstanding. I'm not going to say you don't have to think for yourself from time to time. Stick to the recommended materials and I would pick them out yourself from home depo. I would say all in all I have about $1200 and 30 hours into the standard. That does include weekend dog distraction, soccer and football on TV and an occasional libation.
This plan will save you a lot of stress. Simple, well explained cuts and instructionsto get you throughthe whole build.I'mso stoked to finish up myprojectand soak right away. Joe is amazing! Personalizing my order and even responding to silly questions I had among my way.
