The two symmetry‐independent mol­ecules of the title compound, cevane‐3β,6α,20‐triol ethanol hydrate (2/1/1), 2C27H45NO3·C2H6O·H2O, have the same stereochemical assignments. The six‐membered rings A, B, E and F are in the chair conformation, while ring D is in a boat conformation. The ring fusions are A/Btrans, B/Ctrans, C/Dcis, D/Etrans and E/Ftrans. The verticine mol­ecules are bridged by water and ethanol mol­ecules via hydrogen bonds to form two‐dimensional layers, and the crystal structure is built up by stacking of these layers.
