Listings show sinks made from natural stone (including marble), stainless steel, and ceramic/vitreous china.
Bathroom sinks are offered with single-hole, three-hole, or no-faucet-hole configurations. Some listings note a single pre-drilled faucet hole (about 1-3/8").
Utility sinks often include multi-layer or clog-free drainage systems with removable filter baskets and fast-drain designs. Many vessel-style bathroom basins, however, note there is no overflow hole.
Some utility sink listings specify NSF certification and note 304 stainless steel construction. Other listings reference 201 stainless steel for frames paired with a 304 stainless basin.
Listings include single-basin options as well as multi-basin configurations, including two-basin and four-basin models.
