Aquatic Artists crafted this custom formal marble grotto waterfall on this rectangular gunite pool in Mullica Hill, NJ. The grotto waterfall is handcrafted 100% from marble sourced from a Mediterranean quarry in Turkey and features a beautiful sheet of water cascading over the marble along with two side waterfalls. We designed this grotto waterfall using two different complementary types of marble.  The cap of the waterfall is made from Afyon Cloud Marble while the base is made from Deep Blue Marble.  Also, the overall structure of this water feature is 3 feet high by 20 feet wide and the center grotto is 5 feet wide by 5 feet deep.
