In the structure of the title compound, K+·C6H4BrClNO2S−·H2O, the K+ cation is hepta­coordinated. It is connected to two water O atoms, four sulfonyl O atoms and one Br atom. Further, the sulfonyl and water O atoms in the structure are bridged in a bidentate fashion. The S—N distance of 1.584 (6) Å is consistent with an S—N double bond, The crystal structure is stabilized by inter­molecular O—H⋯N hydrogen bonds.
