I'm happy to say that my gym, which I occasionally use, has a lovely pool and showers and jacuzzi baths plus badminton and indoor tennis courts, outdoor tennis courts, and an 18 hole golf course. I use the tennis and golf facilities mostly,but the others from time to time. It's £60/month, and the golf is unlimited, so try to get a round of golf at any club that cheap! TBH, I am a long-term member and got special offers to stay on when the club changed hands a couple of times, but for me, it's a bargain, especially if I golf 3 x a week.
One guy I know there "lives" in the club, turns up first thing, showers and settles down in the bar/lounge with his laptop and works all day, bringing his own sandwiches for lunch...that's a cheap way to live...but somewhat boring!
