This sink gets the job done in the most classic way with the worlds most commonly used type of bathroom sink. A ceramic round undermount sink that is timeless and will never go out of style. Also available in an oval shape (ABC602) or a rectangular shape (ABC603). Undermount installation is the most convenient because it allows you to swish water from the counter directly into your sink with your hand and makes it so there is no exposed silicone or grout border between the sink and the countertop.
