The design interwoven into the side of the fountain allows you to fully experience the water both visually and audibly. Water softly flows from the top of the orb over the sides into the grooves that lead down into the basin, which produces a pleasant bubbling once it hits the bottom basin. It works great for both indoors and out. Made of fiberglass, this fountain is built to last. Includes 160 gph UL approved pump w/ Adjustable Flow Control.
