PROBLEM TO BE SOLVED: To provide a washing booth apparatus in which the collection efficiency of a coating agent can be kept high by solving the problem that the collection efficiency of the coating agent is lowered owing to the clogging of a water circulating pipeline and the initially set proper ratio of the quantity of water to be used for forming a water screen on the surface of a screen wall to that of water to be used as collecting water for collecting the water in a ventilation passage can stably be kept when water is distributed. SOLUTION: The washing booth apparatus, in which the circulation water in a water tank 18 is pumped up, a part of the pumped-up water is used for forming the water screen by making the water fall down along the screen wall 24 in order to collect a part of the surplus coating agent and the remainder of the pumped-up water is used as collecting water for collecting the water in the ventilation passage 26, is provided with a weir plate 66 for distributing the water which is pumped up from the tank 18 and supplied from a spout 60 to the one for forming the water screen and the one for collecting the water in the passage 26 and a sloped guide passage 64 for supplying and guiding the water from the spout 60 toward the weir plate 66.
