Provided is a liquid dispensing device. The liquid dispensing device includes an internal member coupled to a sink and a nozzle. A liquid processing module is installed separately from the dispenser and may include components to generate, for example, a heated liquid, a cooled liquid, or a liquid having a sterilizing agent. Piping coupling the liquid processing module to the nozzle may extend through the internal member, and one or more components may couple the internal member under the sink. One or more valves may be positioned on the piping to direct fluid from the liquid processing module to the nozzle or to discharge fluid.
