I recently finished making a cedar hot tub. It's wood fired. This was a first for me, and after a hickup or 2 it's all set. It's 6 ft across, and 40 inches deep. It has benches and a set of steps to get in. I welded up the brackets for the bands to hold it snug so it would be water tight. Really crazy project, but fun as well. It is great for a cold plunge in the summer, and heats up fairly quickly when you want it hot. It smells amazing with all the cedar.
