Pro-Series Just-A-Falls Kit w/ Standard Res-Cubes 18" Spillway (7' Stream)

pondless waterfall kit 18 inch spillway options don’t get much more streamlined than this Pro-Series Just‑A‑Falls setup designed to create a clean sheet of water and a natural-looking stream run up to 7 feet. Built around a concealed reservoir system, it delivers the sights and sound of moving water without an exposed pond, making it a practical choice for landscapes where low-maintenance aesthetics matter.

This complete kit is centered on an 18" stainless steel spillway engineered to produce a smooth, glass-like waterfall effect over rock work. The hidden basin uses high-strength reservoir cubes to create substantial underground water storage while keeping the finished feature visually clean. A pump vault with intake assembly helps protect the pump area (pump sold separately) and supports reliable water circulation through the flexible PVC plumbing components provided.

What’s Included

• 18" stainless steel spillway
• Reservoir cube system for underground water storage
• Pump vault with intake assembly
• Flexible PVC plumbing components
• Check valve and fittings

How It Works

Water is recirculated from the underground reservoir up to the spillway, where it returns down the stream channel and disappears into the gravel-covered basin. This approach gives you the look of a stream without the ongoing pond care associated with open water. If you’re comparing configurations, this pondless waterfall kit 18 inch spillway format is especially useful when you want a defined spillway width paired with a compact, concealed water source.

Installation Notes

Typical installation includes excavating the reservoir basin and stream path, placing underlayment and liner, positioning reservoir cubes and the pump vault, leveling the spillway at the head of the stream, and connecting plumbing back to the vault. Finish by backfilling and dressing with gravel and boulders to blend the feature into the surrounding landscape. Choose a pump separately based on your desired flow rate and total head height to get the waterfall effect you prefer.
