In the crystal structure of the title organic salt, C16H19N2+·C9H11O3S−·H2O, the cations pack head-to-tail within a sheet and are aligned in opposite directions in neighboring sheets. The benzene ring of the anion makes an angle of 76.99 (6)° with the plane of the cationic chromophore. The cations are situated in the ab plane, whereas the benzene rings of the anions lie in the ac plane.
