Looks like a pretty cool place for scuba. Different levels under water and a shipwreck you can explore and other things.
Advertised as the deepest but not sure.

They friggin’ stole my idea! But I would have put a ‘sky diving’ simulator place on the roof!
Deepest in Asia, but not the world:
" Nemo 33 is an indoor non-chlorinated fresh water facility in Brussels, Belgium. It held the record as the deepest indoor swimming pool in the world between its opening on May 1, 2004, and the completion of Y-40 in Montegrotto Terme, [Padua])
The pool’s maximum depth is 34.5 metres (113 ft). It contains 2,500,000 litres (550,000 imp gal; 660,000 US gal) of non-chlorinated, highly filtered spring water, maintained at 30 °C (86 °F) by a solar heater, and holds several simulated underwater caves at the 10 metres (33 ft) depth level. Due to the warm temperature in the pool, divers can dive for extended periods without a dry suit. The complex was designed by Belgian diving expert John Beernaerts as a multipurpose diving instruction, recreational, and film production facility in 2004."
