In the title compound, C17H12O4·H2O, the coumarin ring system is approximately planar with a maximum atomic deviation of 0.011 (2) Å, and is nearly perpendicular to the phenyl ring at a dihedral angle of 86.63 (9)°. In the crystal, molecules are linked by classical O—H...O and weak C—H...O hydrogen bonds. π–π stacking is also present [centroid–centroid distance = 3.6898 (12) Å].
