The asymmetric unit of the title hydrated salt, C(6)H(14)NO(2) (+)·F(-)·H(2)O, contains a discrete cation with a protonated amino group, a halide anion and one water mol-ecule. The crystal structure is composed of double layers parallel to (010) held together by N-H⋯O, N-H⋯F, O-H⋯F and C-H⋯F hydrogen bonds, forming a two-dimensional network, and stacked along the c axis, viz. hydro-philic layers at z = 0 and 1/2 and hydro-phobic layers at z = 1/3 and 2/3.
