Wow, I haven't seen this thread since 2016!
I wish we had a pool/hot tub so much. I can't tell you how many of my friends (pretty much all of them) have told me that they would gladly join me nude if we had a pool or hot tub, and they sound completely serious. Of course it's easy to say when the possibility doesn't exist.
But these are friends (especially female) who I would never see in any situations like this without the thrill of water around, so I wouldn't believe it until I saw it, which won't happen anyway.
Such teases!
