Dubai unveils world’s deepest pool creating Guinness World Record, experience underwater city

There is also a unique suspended underwater tunnel which is entirely transparent, so non-swimmers can experience the pool without getting wet.

Before Y-40 Deep Joy's completion on June 5, 2014, the record was held by the Nemo 33 facility in Brussels, Belgium.

Famous for its deep pit, the Nemo 33 pool measured 113 feet - 65 feet less than the Deep Dive.
