Both can be used to cool a single room without ductwork. But a mini-split can add more evaporator units (up to 4) to one condenser unit. So technically it can cool up to 4 rooms.

Do bathrooms need a mini split?

They’re not needed for small rooms like bathrooms, hallways, or walk-in closets. These rooms will get the residual conditioning from the bigger rooms they’re in. Using too many in this way can actually decrease efficiency instead of benefiting it.
