A recirculating rock feature adds movement and sound with a hidden basin, pump, and plumbing set on a compacted, lined base. We core or place a bubbling boulder, basalt column, or urn, then top the reservoir with river rock so the system disappears while water sheets cleanly and returns without splash. Flow is tuned for the space, edges are detailed to keep stone in place, and options like auto-fill, lighting, and timers make care simple.
