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

Jury is out on if I need it. But it looks cool.

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.

What a great build from start to finish! The inventory list to each step by step print outs with a video to help you throughout the process. Cannot thank Joe enough for his guidance!

Once you get a sense of the plans, the opportunities to customize become available. My sauna took about 35 hours to build and sits at about 170 degrees. A great project and a great investment in personal health.

This wouldn't be the first time I'm using Joe's plans to build something. A few years ago, I also built a cold plunge which was super easy to follow and straightforward when it came to simplifying everything. This time around there was a lot more woodworking, but it was fun and again easy to assemble and build. It also required me to get some tools that I never had, which is always fun to learn new skills. Thanks again, Joe.

I’m not a handyman by any stretch of the imagination, but this DIY sauna heater kit was surprisingly easy for me to put together. I installed it in an old infrared sauna as the new heat source and paired it with four 400-watt HotBox sauna bulbs, which give you heat, infrared light therapy, and red-light therapy; basically the best of all worlds in one setup. I just gave it the first test run and everything worked perfectly.

The instructions were solid and the video walkthrough was extremely helpful. Even though not every step is verbalized, the pictures and visuals make it easy enough to follow along and understand where everything goes. One small clarification: the instructions mention pre-drilling the holes in the front of the cedar frame, but they don’t mention pre-drilling the holes in the back as well. Luckily the video showed it clearly, so it wasn’t a big deal.

It definitely took me a little longer than it probably should have, and I even needed someone to help me assemble the cedar square, but the overall build was still very doable for someone with minimal DIY experience.

My only real regret is that I missed the Black Friday deal by about three days — could’ve saved myself some money! So if you’re reading this around Black Friday or Cyber Monday, take advantage of the sale.

Overall, I’m really impressed. The kit is solid, the heater performs great, and it turned my old infrared sauna into a much more powerful and versatile setup. Highly recommend.

I finally have a real sauna! The instructions were great and I’m very happy with the quality and performance of the sauna! Thank you, Joe!

I'm having a hard time finding words of appreciation that can truly express what a great experience this has been. Easy to follow designs. I'm not super handy but with some patience and attention to details, anyone can follow these instructions.

There's also a perfect product line to compliment your build.

Above all else... You cannot beat the best customer experience. Joe took time to respond to an email full of questions on Thanksgiving. The packaging was personalized for me. He genuinely wants you to succeed. Thankful for him going above and beyond to make sure you make a great plunge.

Very pleased with my parts and service!

I just finished building the XL sauna using plans from DIYColdPlunge and I could not be happier with the experience. This was my first major DIY project and the plans made it unbelievably smooth. Everything was laid out clearly with a full shopping list and direct links to purchase which took all the guesswork out of it.

Even with the cheaper bulbs, the XL sauna reached 170 degrees in about 45 minutes which completely exceeded my expectations. I am already excited to see what kind of performance I get once I upgrade the bulbs.

What really blew me away was the customer service. Joe answered every one of my many questions and was there to help the entire way through. You do not see that level of support very often.

If you are considering building your own sauna whether you are experienced or a total beginner, I highly recommend these plans.
