Nature’s Beauty! Bringing the outdoors in is the new aesthetic and Mother Nature is the designer here. Each sink reflects her beauty and will last a lifetime. Casual Elements’ hand-crafted sinks are carved from natural stone boulders and definitely make a dramatic statement. The natural features of each boulder dictate the design elements. Each sink will vary in its size, shape and contours. Additionally, every sink will vary in color as well from light shades of gray to dark grays and black.
