FIG. 3 is a partial cross-sectional view of a bathroom floor pan according to this embodiment.
The drainage basin member 4 is attached to the opening 5, forms a part of the drainage port, and has a rectangular frame-shaped outer peripheral flange 4a protruding in a direction facing the center of the drainage port at the upper end portion. The outer peripheral flange 4 a has an outer dimension that is slightly larger than the opening 5 in the entire circumference in a top view of the floor surface of the washroom, and the back surface of the outer peripheral flange 4 a is disposed on the slope terminal portion 11 b of the surface material 11.
Since the outer peripheral flange 4a covers the entire periphery of the edge of the surface material 11 in the opening 5 from above, it is not necessary to adjust the appearance and the productivity is good as compared with the structure in which the edge of the surface material 11 is exposed. It can be something. Further, even if the dimensions and positions of the openings of the base material 12 and the surface material 11 are varied, the outer peripheral flange 4a can cover the openings, so that there is no need for post-correction work and peeling from the edge of the surface material. It is also possible to prevent the occurrence of curling and the like, which can be expected to have the effect of preventing defects in appearance.
The shape of the drainage basin member 4 and the shape of the opening 5 are not particularly limited, and may be circular as well as rectangular as shown in FIGS.

Only by covering the drainage sloped surface from above from the drainage slope surface, the outer peripheral flange 4a becomes higher than the drainage slope surface, which is inconvenient for smooth drainage.
In the present embodiment, the slope end portion 11b is made steeper than the drainage slope surface 11a, and a difference in slope is provided so that the mounting surface of the outer peripheral flange 4a can be located below the drainage slope surface 11a.
