In the crystal structure of the title compound, C16H19N2+·C8H10NO3S−·H2O, the cations and anions are linked by O—H⋯O and N—H⋯O hydrogen bonds, forming alternating layers parallel to the ac plane. An intramolecular N—H⋯O hydrogen bond occurs in the anion. The crystal structure is further stabilized by π–π interactions, with centroid–centroid distances of 3.7240 (9) and 3.6803 (8) Å.
