We call them “Bubbling Rock Fountains.” The water bubbles up through a hole in the center and rolls down the sides of the rock, creating relaxing sound effects. Indoor water features like the bubbling rock fountains are great for end tables, countertops, night stands, and desks. We have larger floor models too. The fountains also look great in business spaces such as lobbies, waiting rooms, model homes, greeting desks, and conference rooms.
