Drop a quietly elegant water feature into a backyard ground pool or koi pond with this 15.4 in. x 7.9 in. x 1.5 in. / 40 x 20 x 3.81 cm stainless steel waterfall fountain that pours a sheer descent of water from a crescent-shaped outlet. The graceful curve profile keeps flow constant and visually striking, giving the cascade the kind of glassy uniformity that turns ordinary pool walls and pond edges into spa-like focal points. The PQSB-7781 is finely-polished 304 stainless steel with tightly integrated welding, so it resists rust through chlorinated pool water, saltwater splash, and humid pond air without leakage. There's no daily maintenance to schedule and no rust spots to chase — wipe it down occasionally and move on. A single 1.5 in. / 3.81 cm bottom water inlet hooks up to a standard water pump, pressure filter, or flow filter using common pond plumbing, and DIY pond builders or pool remodelers can install it at a swimming pool wall or pond rim without rebuilding the structure. The crescent silhouette pairs naturally with stone copings, wood decks, and natural plantings, making it a fit for both modern pool renovations and traditional garden water features.
