Indoor table top fountains are the easiest and quickest to build. You can use a kit, or assemble the materials and make a custom fountain for yourself. The kits typically include a pump, container, centerpiece, and the various odds and ends needed to complete. Sculptures, driftwood, seaglass, and other items may also be included, if desired. You may use a standard electric fountain pump or some of the newer low voltage pumps.
Decorative centerpieces are available which are already made for fountains.
The container can be of any non-porous material. Candle modules can add interest to your fountain. Larger, more permanent indoor founrtains can be built easily by using bigger tubs, old bathtubs, or decorative basins. Some of the same elements used for table top fountains can be incorporated into these larger fountians. You can also include statuary and other larger decorative items.
