A slate waterfall is a decorative element consisting of a water source, a slate precipice and a catch basin. Manufacturers such as Kenroy offer small indoor waterfalls that need minimal assembly, but large outdoor varieties require construction.
The ideal location for an outdoor slate waterfall is a flat space with an adjacent water source, according to SF Gate. Safe installation also requires a waterproof electrical outlet.
Adding plants to slate waterfalls increases their visual appeal, as stated by SF Gate, and those with water filters accommodate fish. Although exterior slate waterfalls may be installed in any climate, they should be emptied in freezing temperatures.
