Early in the fourth novel of the Outlander saga, called Drums of Autumn, Claire and Jamie are traveling in South Carolina with Stephen Bonnet, among others.
Not enjoying the summer humidity in South Carolina, Claire takes off to wash up in a river.

That said, we can probably guess which bathing scene Maril Davis referred to in her chat with TV Insider.
