Again, not knowing the specific 'the bath' story, but some common key elements could be the bath itself, like its size, shape, and whether it's a modern bathtub or an old - fashioned one. Also, the person or people using the bath, their emotions and intentions. For example, if it's a person looking to relax, that's an important element.
In a 'the bath' story, the water is surely a key element. The temperature of the water, whether it's hot, warm or cold can set the mood. If it's a story about someone sick, a warm bath might be a form of therapy. Also, any accessories related to the bath, such as towels, bathrobes, and soaps are important. They can add details to the story. For instance, a character might be using a special soap that has a unique scent which triggers memories. And the actions of the person in the bath, like scrubbing, singing, or just lying still, are all elements that can make up the story.
