The film was retitled to "In the Deep" in Spring 2016 and given a VOD/DVD release date of August 2nd through Anchor Bay Entertainment and the Weinstein Co. However, one week before the planned release, the film was bought by Byron Allen's Entertainment Studios, retitled back to "47 Meters Down" and given a wide-release theatrical plan for summer 2017 through Freestyle Releasing.

The majority of underwater filming took place at The Underwater Studio in Basildon, Essex UK.

Mandy Moore and Claire Holt learned how to scuba dive for this movie. Neither actress scuba dived before.

47 meters is 154.2 feet.

To replicate the organisms found underwater, finely chopped broccoli was added to the tank. Mandy Moore said it was quite unpleasant after a few weeks, and compared it to filming in soup.

The shark cage and crane were built on a farm in Kent.
