DIY Sauna XL

I used it for the 1st time today, it works but I think I want to upgrade to some better bulbs i was able to get it to 150°. The only reason it hasn't gotten 5 stars is I haven't gotten it to 200°. The cut plan was laid out well a couple of the videos were for the smaller version, but I was able to power through it. I'll update my review once I upgrade my bulbs to the rubylux or the hot box bulbs

Incredibly detailed instructions! Easy build!

Incredibly detailed instructions on the entire build from start to finish! I’ve had my eye on similar saunas but they cost thousands. I’m so happy I found diy sauna, built from ground up solo with no issues.If your in the market for a similar setup, definitely give this a look!

Brilliantly Organized Plans

First, these plans and the video are outstanding! So well organized, there was never a moment wheee I was confused. Color coated cut plan, links in the cut plan for purchase, notes, tips, and videos all work together flawlessly. I haven’t used the sauna yet but the build was great and it turned out awesome. Anywhere there are slight flaws, I would attribute to my lack of ability to get things perfectly square…or slightly warped wood from Home Depot! All this AND Joe was highly responsive to all my emails!

I built the XL version and the cost was more of course.

High quality and easy to follow plans

I recently built a garage sauna using these DIY plans, and the whole experience exceeded my expectations. The instructions are exceptionally clear and beginner-friendly, with detailed step-by-step guidance, accurate cut lists, plenty of helpful photos and video, and measurements, no guesswork or advanced skills required. As someone with just basic tools and average DIY experience, I never felt overwhelmed or out of my depth. The finished sauna is outstanding: it heats up quickly, easily reaches 195–205°F (noticeably hotter and more consistent than any commercial sauna I’ve used), holds temperature beautifully, and delivers fantastic cedar aroma. For the effort and cost, it’s a high-quality, high-performance result that feels like a luxury upgrade—hands down one of the best projects I’ve ever tackled.
