A selectively-illuminable decorative water feature in the form of an assembly includes a base, casing, and a light source in communication with a semi-translucent or translucent fixture. The base may, for example, be a portion of a component/feature of a swimming pool, a spa or a fountain. The casing and light source may be mounted within the base and the fixture attached to a front surface of the base. The translucence or semi-translucence of the fixture creates an illumination effect due to limited transmission of light, emitted from the light source, through the feature. The water feature may take on a variety of forms, including, for example, decorative fixtures, receptacles, a bowl-shaped fixture, and a hand grip attached to a structural surface of a pool, spa or fountain.
