Dubai, a tourism and business hub with desert terrain and months of scorching summer temperatures, has a reputation for flamboyant and record-breaking attractions such as its snow-filled indoor ski slope, large water parks and the world's tallest building.
The pool, which holds the equivalent of six Olympic swimming pools, has been verified by Guinness World Records as the world's deepest swimming pool for diving. Deep Dive Dubai says it is 15 meters deeper than any other.
The facility, shaped like an oyster in reference to the UAE's pearl diving heritage, is also the region's largest underwater film studio, the company said.
Divers go down through a landscape of a sunken city, with sound and lighting. There are two air-filled dry rooms on the way down.
Visitors can practice scuba diving - with a tank of air - and freediving - where divers simply hold their breath.
