If you're "gonna do it", you're have to do it in a way that makes money . . . which is NOT the "right way", except at the very high end.

And, to be 'frank', you have neither the expertise, nor the budget to go there.

Even at the high end, pools are mostly marketing devices for fitness centers, rather than actual focus areas for users. For some reason, many fitness center customers put a lot of importance on a center HAVING a pool, even though the users mostly -- once they join -- do not USE the pool.

I've worked with various fitness centers and country clubs over the years, and can tell you that, almost without exception, fitness center and country club managers HATE their pools, and live in FEAR of them. Operating locally, I was able to 'exploit' that, by providing service contracts through which they paid me to make sure their pool ran as well as possible, given the often half-a## design and equipment they had. But it's not a service I could provide here, even if I wanted to do so.

Honestly, if you can come up with a successful business plan for a budget fitness center that does NOT involve a pool, you'd be wise to do so.
