In the title compound, K+·C7H6BrClNO2S-·H2O, the K+ cation is heptacoordinated by two water O atoms, four sulfonyl O atoms of four different N-bromo-4-chloro-2-methylbenzenesulfonamidate anions, and one Br atom of one of the anions. The S-N distance of 1.584 (3) Å is consistent with an S=N double bond. In the crystal, the anions are linked into layers by O-HBr and O-HN hydrogen bonds.
