PROBLEM TO BE SOLVED: To provide a wash place floor capable of preventing from generation of remaining water on the surface of the wash place floor, especially in the circumference of a drainage recess, without promptly breaking water flow at a downstream side of a drain gutter. SOLUTION: A wash place floor is made of a plastic provided with a drainage recess 6 formed in concave and a surface 2 which is downward inclined slope toward an upper end of the drainage recess 6. A downstream part of a drain gutter 12 formed on the surface 2, in order to guide downstream side water of the drain gutter 12 to a lower part than the upper end 32a of a rising surface part 32 at the drainage recess 6, has water guide gutter parts 21a-21f which are consecutively formed up to a height of the upper end 32a of the rising surface part 32 and a flow velocity reducing part 22 which downstream end is positioned on the surface 2, in order to delay the water flow velocity at the downstream side of the drain gutter 12, is formed so as not to be consecutive to the upper end 32a of the rising surface part 32 and to break off on the way.
