Some thought-provoking answers from various viewpoints - until the inevitable silliness started [
)]
I can see that a shared pool probably wouldn't work unless the upkeep was contracted out and covered by the complex/apartments service charges, or unless you had decent neighbours.
I think that I would try to set up some simple solar heating setup to extend the swimming season - I do not do "cold"!
And yes, I've seen a couple of villas advertised which include a plunge pool rather than a swimming pool. I don't think that would be worth the bother.
It's just so appealing, the whole idea of retiring to the sun and having a pool, isn't it?
