@Stephanie201094 Are you looking for the hot tubs? I'm on XBox 360 and there are three different versions in my game. Go into Build & Buy and select Open Catalog and then Buy New Item. When you see all of the categories select Plumbing > Miscellaneous Plumbing. This is where you can find the 3 hot tubs and the sprinkler.
Is this what you are asking about?
