Measures 13 diam. in.. Interior dimensions: 10.5 diam. in.. Round undermount design. Crafted from solid brass. Standard lavatory d...rain measures 1.5 diam. in.. Finished in brass. Specialty care required. Includes a limited 5-year manufacturer's warranty. Our modern age has given us so many things that are either disposable, machine-made, or both, so a piece like the Nantucket Sinks ROB-OF Undermount Bathroom Sink with Overflow is really something special. This deep basin is made from solid brass with a hand-hammered texture. The polished brass finish has a pleasant natural sheen, and the basin itself provides an overflow drain with a predrilled central drain for a 1.5-inch-diameter fitting. If you leave the basin untreated, it will develop a natural patina over time, or if you wish to maintain its brassy finish, then put on an application of high-quality carnauba wax before the first use and another application every six months following. read more

Dimensions: 16.25L x 16.25W x 7H in.. Interior dimensions: 14L x 14W x 5D in.. Undermount style. Copper construction. Standard lav...atory drain measures 1.5 diam. in.. Finished in copper. Includes a limited 5-year manufacturer's warranty. The rustic feel of the Nantucket Sinks SQRC-OF Undermount Bathroom Sink with Overflow will be a central player in creating a relaxed atmosphere in your bathroom. This wide rectangular sink is designed for undermount use, with a hand-worked body of high-quality copper. The hand-hammered texture brings out the best in the material. This basin is predrilled for a 1.5-inch center drain and an overflow drain. This piece has what is considered a living finish, meaning that it will slowly change over time as the copper is exposed to regular use. If you'd like to maintain the finish that it has when it's brand new, then simply apply a thorough covering of carnauba wax before the first use. The wax will wear off over time, so we suggest reapplying the carnauba wax every six months. Soaps, toothpastes, and everyday cleaners will also wear the finish, so we recommend thoroughly rinsing the sink after each use. read more
