The structure of the title salt hydrate, K+·C6H4Cl2NO2S−·H2O, shows each of the sulfonyl O and water O atoms to be bidentate bridging. The hepta­coordinated K+ cation is connected to two water O atoms, four sulfonyl O atoms and one Cl atom. The crystal structure comprises sheets in the bc plane which are further stabilized by O—H⋯N hydrogen bonds.
