Interior waterfalls come in various designs and sizes. Thus, they can easily be installed in a house, office, shopping mall or even a museum. Let us see what sort of designs and sizes the water falls are available in: 1. Slate water falls: Slate water falls are the most exotic water falls. The moment you see water trickling down gently from slate sabs, you would feel as if you are in a natural water fall. The slate patterns give a very natural look and thus soothe the eyes. It calms the mind and rejuvenates the body totally. 2. Marble water falls are equally popular these days. Marbles exude elegance and that is what makes it stand out from the rest. The vast range of natural colors makes it an ideal choice. 3. Vertical water falls: This kind of water falls are most suited for dead end walls that seem to create a lot of negative space in the room. With the help of thin strings, water droplets fall in straight lines in a vertical water fall and this gives the room a graphic appeal. Vertical water falls is the best choice if you wish to make the room appear larger.
