The sink system includes a sink deck having a sink opening and an outer shell. The sink deck being separated from a sink basin region of a sink basin by a vent ring. A sink basin defines a sink basin region and a plenum region. The plenum region is separated from the sink basin region by the vent ring. A plenum cavity is formed between an internal surface of the outer shall and the plenum region. The vent ring includes a vent with an associated opening. The opening is exposed to the sink basin region and to an area underneath the sink deck, the opening allowing a flow of air therethrough. A dryer is configured to direct forced air through a dryer exhaust port into the sink basin region of the sink basin. ## Claims ### Claim 1 A drying system comprising an outer shell defining a sink deck;
