Abstract: Disclosed is a laundry treatment apparatus configured to condense moisture by supplying cooling water to the interior of a tub containing laundry therein. The laundry treatment apparatus includes a tub, a drum rotatably provided in the tub, a cooling water port provided at the inner rear surface of the tub so as to be adjacent to the inner side surface of the tub in order to supply cooling water along the inner side surface of the tub, and a guide rib formed so as to protrude from the inner side surface of the tub in a radially inward direction of the tub and to extend from the cooling water port toward the front side of the tub in order to disperse the cooling water supplied from the cooling water port on the inner surface of the tub. The apparatus is capable of reducing energy consumption and improving drying performance.
