This Modern 3-Tier Concrete Cast Stone Fiberglass Bowl Water Fountain makes a beautiful addition to your garden or backyard retreat. This trio of bowls is constructed of glass fiber reinforced concrete so it has the look of heavy stone and weathers very well. An integrated battery harnesses the power of the sun to operate the pump but the on-demand technology lets you decide when to use it. You’ll love watching water cascade from the top bowl down to the next two.
