Has anyone built their own outdoor soaking tub setup? I was looking into building a pool but I don't do well with chlorine and it's just too time-consuming/expensive (and would require taking out shade trees which I don't want to do). However, a soaking tub might be a nice alternative. I don't want to leave standing water because I don't want to have to treat the water with chlorine. My idea is to get a large soaking tub or some other vessel that's big enough for one person. I would then harvest rainwater in a 1000 gallon tank and fill the tub with the tank when I want to use it. I live in southern AZ so could use passive (solar) heating to get the water to the right temperature.
I would just like input: has anyone done something like this?
