The Russians appear to be super fond of including extravagant amenities on such vessels. The Typhoon class submarines had pools, saunas, gyms, lounges, etc. https://www.youtube.com/watch?v=JrULRXlAlMU
Somehow, I feel like a short inclusion in "The Hunt For Red October" would have been nice. Pointless to the story, of course, but it would have contributed to the sense of grandeur, impressiveness, and "serious business" of the submarine as a machine.
I recall that at the time the movie was made, nothing was known of the Typhoon class except for spy photos of the portion above the waterline while they sat at the docks. One notable error from the movie was a fight scene between the rows of missile tubes. In reality, the submarines had two pressure hulls stuck side-by-side and that space was filled with water.
