The Titanic's first-class swimming pool was 30 feet long. It was a heated saltwater pool on F Deck, one of the ship's many luxury facilities for first-class passengers.
The pool measured 30 feet by 14 feet and was about 7 feet deep at its deepest point. Its water came from seawater pumped into the ship and heated for bathing. The facility also included changing cubicles and showers, making it a remarkably advanced amenity for a passenger liner in 1912.
The pool was located near the Turkish baths and other recreational spaces, including the gymnasium and squash court. It was not an Olympic-style racing pool: at 30 feet long, it was much shorter than modern competition pools, which are typically 25 or 50 meters. The pool's location inside the wreck is known, but access is blocked by a watertight door, so its present condition cannot be directly confirmed.
