Here are some of the unique aspects of the ship:
grand staircase was a big feature of the Titanic. At the top of the first class
level was a dome. This place is where many waited before dinner.
swimming bath was the first pool on any ocean liner of that day. The pool was
used mostly by first class.
The gym on the Titanic was a place where the passengers to work out. (Work out all those big meals!) The exercise equipment included a rowing machine, and a horse machine. Even the children could use the equipment during a certain period of the day.
This is a picture of what the Grand Staircase probably looked like.
