I'm thinking of buying an inflatable spa for cost reasons but also I don't want it in the summer taking up valuable space on the patio. I like that I can pack it up small and put it away. Even the smaller "portable" tubs seem to range in the 400-500lb weight and that's not going to work for me.
Question is, does anyone use these in freezing winter temps and do they work?
A lot of manufacturers say they are 3-season tubs, but I've seen reviewers comment on using them all year. If it's 104F and you keep it heated, I don't see why they can't be used year round. I don't see this being different than any outdoor spa - heat it or lose it.
Cons that have heard are that the water cools down quickly when cold due to air bubble jets bringing outside air in.
