Nemo 33 was the deepest indoor swimming pool in the world before Y-40 in Montegrotto Terme, Padua, Italy was completed.[1][2] The pool is located in Brussels, Belgium. Its 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) 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 wet suit.[3] There are numerous underwater windows that allow outside visitors to look into the pools at various depths. The complex was designed by Belgian diving expert John Beernaerts as a multi-purpose diving instruction, recreational, and film production facility in 2004. A fee is required of the customers who use the pool.


The pool is open to tourists and professional and amateur divers. The basic regulations require the divers to be aged 12 years or over, healthy, strong, and certified as a diver or supervised by the trainers. For the safety of people who want to dive, they must also have a certified diver as a dive buddy.
