I got a Caldera spa in their mid range line. It is 240V, 5 person, with a salt system and a cover lifter. It cost about $12k USD all told. I love it, but DEFINITELY get the salt system for chlorinating. It would be much more of a pain in the ass without it. As it is, I still love the thing and use it regularly. I check the water chemistry about every five days and it’s super simple to maintain. If I have a party and we are in for extended periods I have to add chlorine daily for a few days but that’s it.
