Guru Maharaj: He came back to Bengal and He delivered Sanatana and Rupa Gosvami in Rama Keli. Then He went to Kanhainatashala, all on the bank of the Ganges. I assume that He bathed also.  And then He came back and stayed in the house of Vidya Vacaspati, which is Ritudvipa, and there He talked to mother Saci. So I would think that when He came back to Bengal, He would have definitely bathed in the Ganges.
