The present disclosure relates to a laundry processing apparatus and, particularly, to a laundry processing apparatus which improves the condensation performance by increasing a contact time and area of cooling water and humid air in a tub. An embodiment of the present disclosure can provide a laundry processing apparatus comprising: a tub in which wash water is stored; a nozzle installed on the upper side of a side part of the tub so as to allow moisture contained in the air staying in the tub to condense, and supplying cooling water; and a guide installed on a rear side surface of the tub to be disposed below the nozzle, and allowing the cooling water supplied from the nozzle to be dispersed in multiple directions and flow downward.
