When it comes to expressing the state of being "unbathed", there are a few different synonyms to choose from. One option is "unwashed", which suggests that someone has not taken a shower or bath recently. Another possibility is "unclean", which can refer to a lack of hygiene as well as a general sense of dirtiness or grime. "Foul-smelling" or "malodorous" are more specific synonyms that emphasize the unpleasant aroma that can accompany being dirty or unwashed. Finally, "filthy" conveys the idea of extreme dirtiness and neglect, perhaps implying a longer period of time without access to washing facilities.
