From a July 26 press release: "Jade Mountain, St Lucia has
just announced that, for the first time, it is now possible for
guests to experience their first taste of scuba diving within the
privacy of their own sanctuaries with private infinity pools. In
suite divers will be provided with custom made, rubber protected
tanks to enable them to be taken into these sublime pools surfaced
entirely in one-of-a-kind glass tiles, specifically designed for
Jade Mountain.
"The pools' textured iridescent surface creates a magical
  underwater environment that lulls divers into a state of relaxation
  and introduces guests to the charm of diving gently. Our new in
  suite diving at Jade Mountain is the ultimate beginner experience.
  It allows guests to sample the serenity that comes with deep
  water diving and the thrill of being under water surrounded by
  no one else but your trusty instructor, without even leaving your
  sanctuary. . . .a trained scuba diving instructor comes directly to
  the guest's sanctuary to guide clients through the basics of diving,
  with a step by step program carried out from the comfort of their
  very own private pool."
The release doesn't say whether a PADI certification will be
  offered.
