Titanic and her sister ship, Olympic, had a heated swimming pool (the first for any sailing vessel), a squash court (the first for any sailing vessel), and the first elevators for second-class.
Titanic's pool was located down on F deck. Altho the Adriatic was the first vessel of all to have any swimming pool, the Olympic-Class vessels had the first heated swimming pool for any sailing vessel.
The R.M.S. had many luxury items on board. The Titanic not only had the first ever heated swimming pool built on board a ship, it also had squash courts and it's own daily newspaper.

Lido is another word for swimming-pool, so I should think the lido-deck is where the pool is.
The Titanic was known for having several luxury amenities on board, but one of the most notable was its onboard swimming pool. This was the first-ever heated swimming pool on a ship, making it a luxurious feature for its time. It was located on the ship's boat deck and was available for first-class passengers to enjoy during their voyage.
The Olympic-Class vessels (including Titanic) had many special things about them. For example: The first heated swimming pool for any sailing vessel, the first squash court for any sailing vessel, and the first ship w elevators for 2nd class.
