My DIY Stainless Steel Hot Tub - Video

I built this many years ago. Everything was designed in CAD, then laser cut and a stainless steel specialist did the welding. He did an amazing job. It takes about 3 hours to go from 7°C to 35°C. The wood consumption is not very high, but it needs small pieces.

Having learned from this I could now build a more efficient stove with more surface area. But there is no point changing it now. It works and its a lot of fun.
