Homemade hot tub

J’s homemade hot tub for under $1,200 – “Hot tubs are really expensive. I can’t see myself turning loose of $5000 to have a hot tub (I want one that much, and it might be worth it, but I just can’t see it). For a self-sufficient guy like me that leads to only one possible conclusion – “I can build one myself.” How hard can it be? Something to hold water, a pump or two, a heater, a filter, and some control mechanism(s). I can do this. I’ve got a machine shop. I can build anything. This is NO PROBLEM…So I got to work…” [via] – Link.
