The asymmetric unit of the title Schiff base compound, C(18)H(27)NO(2), contains two independent mol-ecules in which the C=N bond lengths are 1.278 (2) and 1.280 (2) Å and the cyclo-hexane rings adopt chair conformations. Intra-molecular O-H⋯N hydrogen bonding between hy-droxy and imine groups and weak C-H⋯O hydrogen bonds help to stabilize the mol-ecular structure.
