Abstract: A faucet handle assembly includes a tubular valve body, a valve device, and a handle. The tubular valve body is mounted in a through-hole of a sink. An escutcheon and a locking member are respectively mounted on an upper side and an underside of the sink for clamping the sink. The tubular valve body includes an inlet end in a bottom thereof for communication with a water source. The tubular valve body further includes a side outlet in a lower portion of an outer periphery thereof for communication with a spout. The tubular valve body further includes an outer threading. The valve device is rotatably mounted in the tubular valve body and includes a stem extending through the escutcheon. The handle is securely connected to the stem, thereby allowing joint rotation of the handle and the valve device.
