The crystal structure of the title compound, C15H17BrN2O4S, is stabilized by inter­molecular N—H⋯O hydrogen bonds which link the mol­ecules into centrosymmetric dimers. The dihedral angle subtended by the 4-bromo­phenyl group with the mean plane passing through the hydantoin unit is 83.29 (5)°. The cyclo­hexyl group adopts an ideal chair conformation with the methyl group in an equatorial position.
