In the title mol-ecule, C(11)H(17)NO(3)S, the S atom has a distorted tetra-hedral geometry [maximum deviation: O-S-O = 119.08 (9)°]. In the crystal, mol-ecules are connected by inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, forming layers of mol-ecules aligned parallel to (110). The 2-methyl-propan-1-ol group of the mol-ecule is disordered over two positions with an 0.592 (4):0.408 (4) occupancy ratio.
