Be careful when looking for hot tubs. There are hot tub forums similar to Pinside. Not all hot tubs are created equally. My first hot tub purchase was in 2002. Brand new hot tub, I took extreme care with it, did everything by the book. It went through three different pumps, two Motherboards, and an ozonator in 5 years. The final straw was when the 2nd motherboard crapped out when we were gone in the dead of winter and two of the main PVC feeds both cracked/broke. I gave that one away for free, and swore I would never have another hot tub.
Fast forward 10 years and I have had two knee surgeries and have a ton of cartilage missing courtesy of severe arthritis. The hot tub has been my saving grace.
That being said, before I dove back into the hot tub world, I did a ton of research to see if my first experience was a normal one. It appears that a combination of cold Wisconsin winters and various manufacturers can make for a poor experience similar to my first one. This second go round, I started looking at hot tubs that were more favorably reviewed from the "tried and true" manufacturers. It turns out, those tubs were typically in the $7500 range this time around. So I went back a few years and looked for hot tubs made in the last 5-10 years that were found to be reliable. I found a project one (the one I pictured above) and restored it back to its former glory. It has been 1 year so far, and absolutely zero problems. It has been a completely different experience than my first one.
I will say if you can find a way to have 220 run to it instead of 110, do it. The 110 tubs seem to be a bit under-powered for what they are supposed to be. Many of them don't even support the heating element and the jets being on at the same time using 110.
