We are having a play ship built that will be installed near the pool and from which will come 2 slides. I have just realized that pool slides that you can buy from S R Smith or Interfab (probably fiberglass?) cost almost as much as our entire 3 story play ship (water cannons and all!). I assume the slides we are getting are really intended for playgrounds rather than pools. Also, I received a recommendation from SR Smith for a diving board that is especially for SWG pools which makes me think that the salt may be damaging for the regular propylene slides. For what we are paying, I wouldn't be upset if we have to replace the slides every few years. Does anyone have any experience, warnings, or thoughts on this?
