Possible Spoilers ahead.

Rogue One takes place just before A New Hope putting it approximately 19 years after the events of Revenge of the Sith. Seeing how it's been nearly two decades since his dismemberment and burning, what's the point of putting Vader in a bacta bath now? If it would have really helped him regenerate, Palpatine would have had him in one soon after his defeat on Mustafar, but instead immediately took him to surgery and had cybernetics attached. I also don't think it had any pain management purpose because Dark Side users often draw on pain to fuel their Force abilities, so it is unlikely a Sith Lord would try to reduce their own pain.

    I assumed that scene was implying he needs to be immersed in bacta on a regular basis to help prevent his injuries from getting any worse than they already are.

The container is referred to as a "rejuvenation chamber."

Vader’s attendant, Vanee, visits Vader as he meditates within a rejuvenation chamber.

Rogue One: The Ultimate Visual Guide

While in Legends this is simply another word for a bacta tank, the word “rejuvenation” suggests to me that Vader is being restored to a usual state: that he is doing damage to his body, and needs to repair it to remain functional. Considering what a wreck he is physically, and the exertion he frequently engages in, it’s not a surprise that he needs frequent treatments even to stay in a workable state.

It is true that, as a Sith Lord, his pain gives him strength:

Without the neural connection to his armor, he was conscious of the stumps of his legs, the ruin of his arms, the perpetual pain in his flesh. He welcomed it. Pain fed his hate, and hate fed his strength. Once, as a Jedi, he had meditated to find peace. Now he meditated to sharpen the edges of his anger.


However, there must be a balance. Too much pain will disable him, Sith Lord or no, and he must be able to fight and enforce the Emperor’s will.
