12” Adjustable with half-round base. This can be used in a wide range of garden containers. It's the perfect scale for most garden scenes, making it especially versatile. This is a popular fountain because of it's size. The bowl is not included. Sometimes pottery bowls for plants are the most attractive. I use one. I put a rubber stopper in the hole in the bottom and used silicone to seal it. It's fairly wide and can handle the extended stream.
