Indoor water features tend to be slightly smaller & their design bear in mind the noise levels, water splashing when building the lift levels for the water tube inside of the body, the dimensions of the water base & tank as well as the choice of water pumps. Indoor water fountains come in a variety of styles including table top, free standing, wall fountains, wall hanging, or commercial fountains that you can see in hotel lobbies, in commercial high rise buildings’ reception areas and by pillars and lifts in exhibition halls and large commercial hubs & airports.
