Slate Boulder SB9 is a delightful wide rectangular boulder style water feature with a sloping face which the water cascades down effortlessly. The large horizontal top face creates a lot more interest than a vertical monolith, as the water falls much slower and creates mesmerising patterns across the natural stone.
