I'm often don't which noun to use, but I can think of a verb to describe it.
I know that 吃的 (to eat + 的) means food, so I was wondering if I can use it with other verbs as well, like 洗澡的 (to bathe + 的）can mean bath?
I think most of these verb+的 noun are all following a law that the verb must be a transitive verb.
means something can be eaten or drunk
However for intransitive verbs, they are not able to construct verb+的 nouns, for the reason that there are no passive structures.
洗澡的 is a really strange usage. Though it can be used as a transitive verb, the passive structures for bathe is not common to used in daily life.
Besides, verb+的 is a very informal usage that they are mostly only used in oral Chinese. For more formal ways, there are some other words that can be used, like
食物 饮品 for food and drinks.
