The ribbed sphere design elevates traditional fountain aesthetics with its textured, architectural surface. As water cascades over the saw-cut grooves, it creates an ever-changing pattern of ripples and waves—a living sculpture that brings movement, sound, and tranquility to your outdoor environment. The natural granite ensures each sphere is truly one-of-a-kind, with subtle variations in color and texture that enhance its organic beauty.
Installation & Care
Each kit arrives with all necessary components for installation. The concealed basin system houses the pump and reservoir beneath the decorative pebble surface, creating a clean, professional appearance. Position the basin, set the sphere, connect the pump, fill with water, and adjust the flow to your preference.
Routine maintenance includes monitoring water levels, periodic pump cleaning, and seasonal winterization in freeze-prone climates to protect components.
