Copper bathroom sinks come in two different varieties. You can have a standard surface mount sink or an under mount sink. The difference is where the sink is attached to the base. The surface mount actually sits above the hole in the counter and it is held in place with gravity and silicone sealant. The under mount model is normally attached with either clips or screws to the bottom of the counter.
Benefits of Copper Bathroom Sinks
One of the main benefits of having copper bathroom sinks is that they offer you an easy way to keep your bathroom sanitary. Copper is naturally resistant to bacteria and mold, so you will not have the problems you can encounter with other sinks made from porcelain. Copper will not rust, so you will not have to worry about some water staying in the sink and causing damage to the metal.
