DIY outdoor soaking tub

[evme]

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?

Hi,

My friend here did something similar just using an old hot tub shell. The passive heating was a bunch of black tubes in a glass window box that would get it pretty warm with a solar pump. It is a passive drain-back system where he used pex coils like this : https://rimstar.org/renewnrg/diy_pex_solar_hot_water_thermal_dn.htm . It worked well but it was never really" super"hot., He had the boxes mounted to the roof of a shed and would flip the pump on and off. Mother Earth News had some nice articles on solar water heating in general https://www.motherearthnews.com/green-homes/build-a-passive-solar-water-heater-zmaz07onzgoe .

good luck!

If you are anti-chlorine, go with a salt water setup.

Yeah, I'm interested in that route. Is it expensive to do for a small pool though?
