Inflatable hot tub?

I think the inflatable would be nice. We had an 8 ft x 8 ft fiberglass one for awhile. The first month we used it everyday. The second month a few times a week. The third month once a week. Then once a month. Meanwhile, the electric meter was spinning furiously. The cover was so big my wife couldn’t handle it by herself. We sold it off cheap.

I really like the idea of being able to put it away for awhile when you get bored with it. Thinking about buying one.

I like the square one it kind of seems like it gives you more leg room sitting crisscross and stuff like that. I put two 4x8 sheets of three quarter inch palm down and then got four by eight sheets of half inch plywood and made a surround. I put a little 2-ft doorway in it.. and I got two more three quarter in sheets of insulation from to set over top of it inside that plywood surround that keeps it warm..
