Stainless Steel Bathroom sinks create a modern sleek feel with the durability that stainless steel is famous for. Stainless steel bathroom sinks come in a wide variety of shapes and depths. Stainless steel sinks can shine with a polished finish or have a brushed finish to hide fingerprints. There are also so many styles to choose from, like vessel, undermount or topmount sinks. Topmount stainless steel bathroom sinks (also called drop-in or self-rimming sinks) can have one to three pre-drilled holes for the faucet.
