Create a stunning natural water feature with this set of three basalt columns, designed to bring the beauty and tranquility of real stone to any outdoor space. The columns measure 12", 18", and 24" tall, each approximately 6" x 6" wide, and are core-drilled with a 1 1/4" (32mm) hole from end to end. The final 1 1/2" is enlarged to 1 3/8" (37mm) to accommodate and conceal the light ring. Each set includes three basalt columns, an FBL48 Sturdi-Basin with support blocks, a Tranquil Décor MP1000 pump, splitter and plumbing kit, and an LED8B3 light kit for beautiful nighttime illumination. Because basalt is a natural stone, each column will vary in size, weight, and color, making every set unique. Stones, wood, plants, and surrounding fixtures shown in images are not included.
