Polished Pebbles for Fountain Basins, 40 lb Bag
High-polish river pebbles are the finishing layer on a fountain basin, hiding the grate and catching the light as the water runs over them. Choose solid black or a natural mixed blend.
• 2–3″ Pebbles: high polish, natural variation in shape and size.
• Black or Mixed: match the stone of your fountain.
• About 18″ × 18″ per Bag: Blue Thumb's recommended coverage, or up to 24″ × 24″ with a thinner layer.
