Most of the wall fountains are self-contained, which means that they can be directly used by mounting them on the wall, or a post. You just need to add water, plug in electrical outlet, and fountain starts working. Most of the fountains have a variable speed control, which enables controlling the flow of water.
Nowadays, garden wall fountains are crafted from several materials like sandstone, marble, copper, fiberglass, etc. However these fountains are capable of enhancing the beauty of any garden, but they are considered ideal for small gardens, where there is not enough space to install a big garden fountain. The garden wall fountains are elegant pieces of art, but their increasing popularity can be primarily credited to their reasonable prices and space efficiency attributes.
