DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom entrance / exit structure.

[0002]

2. Description of the Related Art Conventionally, in a bathroom in which a door frame is constructed so as to be substantially flush with a washing scene in order to reduce a step on a floor surface at an entrance of the bathroom, the washing scene side to the door frame side. In order to drain the flowing hot water, a large-diameter drain port is required. For example, as disclosed in Japanese Patent Application Laid-Open No. H10-205237, a separate drain groove is formed outside the waterproof pan forming the bottom of the bathroom. Conversely, a drain groove is formed inward, and it is necessary to separately provide a drain groove by projecting outward.
