The Titanic's squash/raquet court was located on G Deck with the entrance on D Deck.The room was staffed by an instructor, like the gymnasium. The facility included a viewing gallery on F Deck above. It cost $0.50 for a reservation in 1912, a price which would be approximately equivalent to $12.39 in 2017.
Entry was on D Deck, with a single staircase leading down to E Deck and then down to F Deck. 1st-Class passengers would then turn right and head back along the stairway before turning right again and passing the Spectator's Gallery. They would then descend a stairway to G Deck and turn right once more, before opening the door leading to the Squash Court.
The room flooded just minutes after Captain Smith gave the order to send for help.
