So I picked up an older Great Lakes round spa a little over a month ago for real cheap. I replaced the heater element, both heating relays, and stained the wood. Works great, looks great. Over the past few days I picked up two more tubs! One is an older Hot Springs 120v that included a two place snowmobile trailer ($75 for both) and the other one is a late 90's Great Lakes 6-person, two motor, blower, and ozonator for $100! It has a "small leak somewhere", otherwise is in perfect condition. Pictures of both can be found here http://www.lilevo.com/hottub/ 1.) Can I throw in a no-fault 6000 into the Hot Springs tub? It has a small diameter hose in and hose out for heating. Looks like it would work perfect. 2.) How much would you pay for the round Great Lakes tub? I want to list it locally and keep the larger Great Lakes. I'm pretty sure I'm addicted to hot tubs now!

Tub looks outstanding...not a bad addiction to have! It always amazes me how nice an older tub can look with some work and dedication.

Not sure about the no-fault heater into that older Hot Spring Sovereign. I'm not sure how you would adapt the 2 temperature thermistors to the old style control box which has a gas filled probe for the thermostat temperature control.

I like the way you think though...keep up the good work. I also like that last picture...looks like you are on your way to opening a used spa store!

Your project reminds me to take more pics of the rehabs that I do. It is inspiring to see the nice work done by others.
