What Makes This Fountain Special
The black granite ribbed sphere elevates contemporary outdoor design with its bold, sculptural presence. As water cascades over the textured grooves, it creates an ever-changing pattern of ripples and waves—a living sculpture that brings movement, soothing sound, and sophisticated drama to your outdoor environment. The deep black granite provides stunning contrast in garden settings and pairs beautifully with modern architecture, natural stone, and minimalist landscapes.
Design Versatility
The dramatic black finish makes this fountain exceptionally versatile. It creates striking contrast against light-colored hardscapes and greenery, serves as a bold focal point in monochromatic designs, and complements both contemporary and traditional landscape styles. The ribbed texture adds depth and visual interest while the spherical form maintains timeless appeal.
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 to prevent debris buildup, and seasonal winterization in freeze-prone climates to protect components.
