This ceramic vessel sink is just an example of the exquisite beauty the Mexican craftsmen put on each talavera item they create. It is handcrafted and hand-painted. It has a round base (where it sits) about 6"" in diameter and 1"" tall, which means, the inside dimensions are about 14"" by 4 1/2"" deep. It doesn't have an overflow system. There might be small differences in size, weight and even the colors.
