We are moving into a new home this summer and I was planning on getting a pool. However, due to the size of our yard, I am now toying with the idea of getting a large hot tub and using it as both a hot tub during cooler seasons and a mini pool during summer. Has anyone done this? How did it work out? Any suggestions on brands/models? Any special features I should look for? I know nothing about hot tubs so any help would be appreciated!
