World's deepest indoor dive pool will be as deep as a 15-storey building
The world's deepest indoor pool is set to open in Poland this spring and will allow swimmers to dive 45m below the surface.
Created as a training site for divers, the Deepspot diving pool will hold 8,000 cubic meters of water when completed - that's 27 times more water than standard 25-meter pools.
And how deep will it be? At a depth of 45m, the pool will be as deep as a 15-storey building.
For a more comfortable dive experience that will also allow free divers to forego wetsuits, water temperature will be warmer than standard pool temperatures.
Water will also be filtered 15 times a day to keep the pool transparent and clean for both divers and outside spectators: designs call for a transparent, underwater tunnel, while conference, training and hotel rooms will also have a view of the underground pool.
By comparison, traditional pools are filtered an average of three times a day, says Deepspot.
The pool opens in Mszczonow about an hour's drive outside Warsaw, by the same group that operates an indoor skydiving attraction, Flyspot.
