A washing machine includes a water tub improved in strength and configured to reduce an amount of washing water consumed by the washing machine. The water tub has a bottom part, and a body part upwardly extended from a periphery of the bottom part by a certain height. The body part includes at least one annular stepped portion to reduce a diameter of the body part. The water tub includes a first annular stepped portion formed at a middle of the water tub, and second and third annular stepped portions formed above and below the first annular stepped portion, respectively. The body part of the water tub is widened upwardly. Hence, the washing machine has a water tub that is strengthened and able to reduce vibration.
