My wife and I are kicking around the idea of getting a plunge pool. We are kind of up against it space wise, so this would be a good alternative. It’s actually a pool and hot tub separated by concrete.
I can only imagine what the waiting list is for this, I haven’t called yet to kick the tires, but we’d need to take out some equity in the house to do it.
