11 Trivia Tidbits For Your Next Pool Party

At Aqua-Tots Swim Schools, we’re big proponents of swimming pools (obviously), and National Swimming Pool Day is observed annually on July 11th. As such, we’d like to offer 11 Trivia Tidbits about Swimming Pools. (Because everyone needs these tidbits of valuable information for their next pool party.)


Swimming pools were invented in the first century B.C. by the Romans, and many of their pools were heated using water diverted through piping from natural springs. 


The Adriatic (sister ship to the Titanic) was the first cruise ship to have an indoor swimming pool, which was also the first pool to cross the Atlantic Ocean in 1907. That’s one way to swim across the ocean!


The White House has had two swimming pools since the 1930s. President Roosevelt had an indoor swimming pool installed in 1933, but President Nixon later had it built over for a press briefing room. In 1975, an outdoor swimming pool was installed on the White House grounds by President Ford.


Olympic sized pools have enough water to take over 9,400 baths. That’s 660,000 gallons of water, and the average bath contains 70 gallons. Scrub-a-dub-dub!


The average person swims in a pool six times a year, while some competitive swimmers swim 365 days a year.


California has the most swimming pools with over 3,000,000.


These five states report the highest number of in-ground swimming pools, and it doesn’t come as a surprise that the top 4 are toasty locales. 

  • California
  • Florida
  • Texas
  • Arizona
  • New York


There are 10.4 million residential swimming pools in the United States. There are also 309,000 public swimming pools, according to the Association of Pool & Spa Professionals (APSP). That’s a lot of opportunity to use some good ‘ol swimming skills!


The world’s largest swimming pool is located at the San Alfonso del Mar resort at Algarrobo on Chile’s southern coast. It is more than 1,000 yards long, covers 20 acres, has a 115-ft deep end and holds 66 million gallons of water. 


The Lexis Hibiscus Port Dickson resort in Malaysia holds the Guinness World Record for the most swimming pools in a resort with 643 swimming pools! Each villa at the resort has its own private swimming pool. Bliss!


At 138 ft, Y-40 in Italy currently holds the record for the world’s deepest pool, and it’s the only one for divers with thermal water.

However, it won’t be the record holder for much longer. The Deepspot is set to open in Poland later in 2019. At a whopping 148 feet, this pool will be complete with underwater caves and overhangs.

But wait just a second, it gets deeper! The Blue Abyss is expected to open in Britain in 2020 at an astounding 164 feet. How low can you go?!

At Aqua-Tots Swim Schools, we want you to have all the facts. Even the fun ones!
