Abstract: According to the embodiment, a toilet device includes a detector and a controller. The detector is detecting whether or not flush water is at a position lower than a full level and higher than a seal level at a surface of a bowl of a flush toilet. The controller is determining a clog state of the flush toilet based on a detection result of the detector after a flush water supplier is closed. The flush water supplier is located in a flow channel discharging flush water into the bowl. The position of the detection region of the detector at the surface of the bowl is separated from flush water flowing in a vertical direction from a water discharge port of the flow channel toward a bottom portion of the bowl after the flush water supplier is closed.
