What was the largest room in the Titanic?

Answer 1

The longest and widest room on the Titanic was the First Class Dining Saloon located on D Deck just aft of the Grand Staircase. It could hold 500 passengers and spread the width of the entire ship.

The Tallest room however, was the Reciprocating Engine Room located on the Orlop Deck between funnels No. 3 & 4. This room rose several stories all the way up to E Deck from the bottom of the ship.

Answer 2

5856 rooms.

There is actually not a set number, as there cannot be, because many of the third class cabins were made with adjustable and retractable walls that could be opened for larger quarters for families and closed to accommodate individual passengers. There were several other rooms of this nature, where one large room was able to become several smaller rooms if partitioned off with the retractable walls.
