When it comes to describing someone who's sweating profusely, there are a number of different ways to go about it. Some options for synonyms for the phrase "bathed in sweat" might include "drenched in perspiration," "soaked through and through," "sopping wet with sweat," or simply "sweat-soaked." Other possible choices could include "dripping with sweat," "covered in a sheen of sweat," or "marinating in their own perspiration." No matter which synonym you choose, the goal is to convey just how thoroughly the person in question is sweating, and to paint a vivid picture of the discomfort they must be experiencing.
