I've been toying with the idea of getting one. I have a finsihed room behind my garage (about 12x6 i think ???) thats carpeted and all that and leads to the laundry area/hot water tank. I've been thinking about putting a hot tub/spa in there. But, I know nothing about them. first, I'm a lazy shit.... err, busy ??? no lazy is better.... so if it required a lot of up keep, its probably not for me. So hot tob owners, what all is involved in maintaining one? is it a huge power/electricty eater? do you turn it on only when you use it, or leave it on all the time?
