Plan Overview
The DIY Sauna Plan is a step-by-step guide that walks you through building a 175–220°F capable sauna for a fraction of the cost of buying one.
FYI –This isn’t a cookie-cutter cornhole board printout… It includes:
- Complete shopping lists with direct links
- Detailed cut plans for two sauna sizes
- Color-coded assembly diagrams
- Video tutorials covering every aspect of the build.
It’s designed for first-timers—clear instructions, easy-to-find materials, and pro-level results.
Think of it as having a buddy who’s already built it, showing you every step 👍

Total Cost?
The DIY Sauna is about $1,200–$1,300 all-in... right down to sandpaper and screws.
That's literally thousands less than buying a prefab sauna — plus you get the pride of saying "I built this myself."
Here's the breakdown.
- DIY Heater Kit & Plan – ~$550.00
- Dimensional Lumber – ~$60.00
- Cedar Boards & Lumber – ~$210.00
- Exterior Panel/Board – ~$160.00
- Screws & Nails – ~$60.00
- Casters (Optional) – ~$35.00
- Magnets & Hinges – ~$12.00
- Vapor Barrier & Foil Tape – ~$90
- Insulation – ~$55
- Stain & Oil – ~$30
- Brushes, Sandpaper, etc. – ~$10
Grand Total (Estimate) ~$1,272.00
Dimensions?
If you build based on the plan, you’ve got two sizes available (see diagrams & images above). The beauty of DIY, however, is that you can customize your build to suit your needs.
The "Standard" – ~54" x ~31-1/2" x ~46"
The "XL" – ~60" x ~37" x ~50"

Tools Needed?
I designed this build to be completed using basic tools – ones you likely have on hand or could easily borrow from a friend.
The required tools are in bold below, but life is easier if you can at least gain access to everything listed here.
- Miter Saw or Circular Saw
- Jigsaw
- Drill
- Orbital Sander
- Brad Nailer
- Pocket Hole Jig
- Hammer
- Tape Measure
- Framing Square
- Utility Knife
- Scissors
- Pencil
- Sharpie
Heat Source?
I recommend using the DIY Heater Kit for this build – yes, I developed it myself but it is truly the most cost-effective heater for this style of sauna on the market.
It utilizes four IR heat lamps and can easily heat the sauna over 200°F, provides red light and infrared therapy and reduces EMFs.
So is it infrared or... ?
The DIY Sauna is the best of both worlds. It heats to traditional sauna temperatures AND packs the benefits of infrared heat.
If you want the full list of recommended heaters, shoot me an email and I'll send you the heater section of the DIY Sauna Plan.
Recommended Bulbs?
There’s a number of options out there for these bulbs – there’s nothing new here in regard to sauna therapy, they’ve been used in sauna products (and even bathrooms) for years. They come in either 275W or 375W.
I’ve tested a good amount of bulbs and have my top recommendations linked in the plan and an overview in this YouTube segment.
Power Draw? Cost to Run?
The Heater Kit pulls about 8A with four 275W bulbs, and about 12.5A with two 275W and two 375W bulbs.
With heavy, daily use you can still expect operating costs to be less than $100/year. That’s literally pennies compared to a spa membership.
Heat up times?
Ambient temperature plays a factor here, but from cold start, it hits sauna-level temps in about an hour.
There's a table above that shows what to expect but most customer reviews say it heats up faster – feel free to read up on the reviews below 👍
Customer Reviews
Built the XL Sauna and bought the heater kit. Followed all of Joe’s steps and recommendations and I love my new sauna.
I am very much a novice when it comes to building things. And while it may have taken me a bit longer than most, the detailed plans and videos allowed me to succeed where I couldn't have on my own. I did make one mistake... I let Home Depot select my framing material so I could just pick it up. Some of those boards were as straight as a wet noodle! But it still worked out great in the end. The sauna is build to last. Now the modifications can begin!
Excellent plans, thorough, easy to follow! And the best part of DIY, changing it up a bit to make it your own. Fantastic! Thanks Joe!
Great to bridge that mental gap and start your project. Great plan.
Thanks David! Really appreciate the review. I appreciate the 4-Star (sometimes I worry that folks think I'm spamming these when they're all 5-Star... But I'm curious what I could have added to make it a 5. Appreciate your feedback
Couldn't say enough to describe how awesome this thing is. The plans were so well put together and easy to use. Had a really good time building it. Everything is very well organized and easy to follow. And Joe was amazing. He answered all my questions very quick. And I had a lot of questions. Probably too many. I even ran into some issues with my local Home Depot not having what I needed and Joe found me some alternate options. He was so helpful. He put in way more work than what I paid for. Super grateful for this setup and everything that it came with. I also used the DIY Heater and the 2 vents and they were super easy to install. I went with the XL build and I’m glad I did. I’m 5’11” 200 pounds and it’s comfortable. I will say having the 375W bulbs might be better in terms of heating it up quicker. I haven’t tried that but I will next. Highly recommend to anybody who’s on the fence about it. Couldn’t say a negative thing about it, and Joe was awesome. Super grateful!
