Abstract: A water level and temperature indicating device useful for signaling preset desired water levels in a bath tub and indicating air and bathwater temperature. The device has suction cup means for removably securing the device to the tub ledge. A depending float chamber and temperature probe for projecting into the bathtub, a battery operated audible alarm system and a battery operated digital thermometer device. An interchangeable weighted float of various lengths is housed within a float chamber. The float chamber has a removable screen unit to facilitate float changes which determine desired preset water level. A modified push on switch within the float chamber will complete an electrical circuit and sound an alarm when a desired preset water level is achieved. The thermometer device will indicate air temperature until it makes contact with the water. While in contact with water the thermometer device indicates water temperature.
