  However, in the bathroom floor connection structure described above, in order to form a connection structure in order to fix the flange pieces extending horizontally from the upper ends of both wall portions of the bathtub floor and the washroom floor in a vertically stacked state, The required area in plan view increases. For this reason, the problem that the effective area (area in the planar view which can be used as installation of a bathtub, a washing place, or can install another member, apparatus, etc.) in a bathtub floor or a washing place floor has arisen.

  The present invention has been made to address the above-described problems, and the object of the present invention is to reduce the area in plan view occupied by the connection structure between the bathtub floor and the washing floor and increase the effective area in the bathroom. Another object of the present invention is to provide a bathroom floor connection structure capable of reducing the size of a bathroom.

  In order to achieve the above object, the structural feature of the bathroom floor connection structure according to the present invention is that the wall portion having the connection portion is provided along the edge portion at the opposite edge portion of the bathtub floor and the washing floor. The connection structure of the bathroom floor is configured by connecting the connection portions in a state where both connection portions are stacked one above the other, and the inclined surfaces inclined by a predetermined angle from the horizontal surface are formed on the opposing surfaces of both connection portions. It is to have done.
