The Wave Glass Specialty Vessel Bathroom Sink features a free-form wavy, round shape, and a textured exterior. The sink comes in a 14 in. size, which is perfect for smaller bathroom spaces. Each clear sink has a lightly frosted exterior and is made of high-quality tempered glass, which creates a faint greenish coloration. They recommend that you also purchase a mounting ring and drain with your glass sink in the same finish of your faucet.
