Crafted from 70% crushed natural stone and minerals blended with resins, Ruvati’s epiStone series of bathroom sinks are available in a 19-inch-by-14-inch curved-vessel base Canali model and a 23-inch-by-15-inch straight-sided Omnia model. Ruvati says the nonporous surface is easy to maintain, and the oval silhouette was designed with water drainage and cleaning in mind. The sinks come in five colors ranging from matte white to avocado lime green.
