Crafted as the compact sibling of full-size pool spillways, this 11.8 in. stainless steel pool waterfall brings a satin-smooth glow to small backyard pools, koi ponds, and bowl fountains where a wide-span unit would overwhelm the wall. The 11.8 in. x 4.5 in. x 3.2 in. (30 cm x 11.5 cm x 8 cm) SS 304 stainless steel body is tightly welded for a sealed, leak-free housing that holds up to chlorine, salt-water, rain, and freeze-thaw cycles without rusting at the seams. Inside, a waterproof RGB LED strip lights the falling water from below the surface in 18 different colors, with brightness and rhythm presets driven by an RF remote so the water feature shifts mood without anyone leaving the lounge chair. A broad, bevel-open outlet and a bottom inlet shape the flow into an even, ribbon-flat sheet across the full 11.8 in. lip, producing a quieter, more meditative fall than splashy nozzle-style fountains. A single 1.3 in. (32 mm) female-thread connector mates with standard pool pumps, pressure filters, or flow filters, supporting embedded installation behind a finished wall or external wall mounting on existing hardscape. With a 10 W / 110 V RGB driver, the spillway draws modest power for evening operation, and daily maintenance is limited to the occasional surface wipe-down.
