20" Ribbed Black Limestone Sphere Fountain Kit
A 20-inch black limestone sphere with an irregular saw-cut ribbed texture. Water flows over the ridges in a mesmerizing wavy pattern before disappearing into a hidden basin.
The saw-cut ribs give this sphere its character: rather than sliding off in a smooth sheet, water ripples across each ridge and forms a wavy pattern down the dark stone. Its "transitional" design reflects today's popular color trends and works in modern and classic landscapes alike.
At 20 inches across and about 285 lbs, it's a substantial focal point that still fits comfortably in a patio bed, entry garden, or courtyard.
Natural stone with a deep, dark tone that turns glossy when wet.
Irregular saw-cut ribs create a mesmerizing rippled flow.
Sphere, basin, pump, valve, plumbing, and pebbles included.
Water vanishes into a buried basin — no open pond.

Will my sphere look exactly like the photo?
This is natural stone, so color, texture, and pattern vary slightly from piece to piece.
How heavy is it?
About 285 lbs, so plan for help or equipment when placing it. Freight charges apply — call for a quote.
Do I need a pond?
No. Water recirculates from a buried basin hidden beneath the included pebbles.
What about winter?
In freezing climates, remove the pump and drain exposed plumbing before a hard freeze.
