Fun project with good Instructions

This came out even better than expected. It’s a solid build with simple to follow instructions. Only update would be that the app needed for the heater has changed to “BN-Hub”.

XL Sauna

I couldn’t be happier with this DIY sauna purchase. The plans were clear, well-organized, and very easy to follow. The video tutorials were especially helpful and walked through the key steps in a way that made the whole process feel simple and manageable.

The heater kit was high quality and worked perfectly with the build. Everything functioned exactly as described.

Overall, a smooth project with an amazing end result. I’d absolutely recommend this to anyone considering building their own sauna!

Detailed plans

Detailed plans. I wish that the directions for building your own light were included and that there was a video for the XL version.

Pleased with the results.

The project took me about 2 weekends to complete between rounding up supplies and assembly. The temps will make it above 200deg if given time 1.5hrs. I’m 5’7” and after a couple of weeks of use believe the larger build would have given me more room to move about once inside. Over satisfied mostly. Maybe move the heat source a tad lower. Could help with warmer temperatures lowering the box on the legs and torso?

Thanks for the detailed plans and prompt answers to any issues I had!!
