2. Description of the Related Art In Japan, with the aging society, families with only elderly couples and families with elderly people living alone are increasing. In the case of elderly people, if there is any step at the entrance when trying to get out of the bathroom, there is a risk of falling down and falling and injuring the corner of the entrance.

[0003] In order to safely take a bath even for a person with a weak leg such as an elderly person or a physically handicapped person, the step between the bathroom and the entrance and between the entrance and the next room such as a dressing room or a washroom is set to 3 mm or less. A bathroom unit having a structure called barrier-free has already been proposed.

[0004] In such a bathroom unit, there is a risk that hot water or water used in the bathroom may pass over the entrance and exit the bathroom instead of reducing the steps at the entrance. Therefore, in such a bathroom unit for the purpose of barrier-free, Japanese Patent Application Laid-Open No. H11-2699.
As in the bathroom unit described in JP-B-56, a drain gutter is provided as a drain receiving portion below a lower frame provided with a rail or the like for receiving a door of an entrance from below, and hot water or water flowing from a bathroom side into a door sill portion is provided. Is received by the drain gutter, and can be drained to a drain pipe from a drain port provided in the drain gutter.

[0005] However, there may be a case where a protrusion such as a bathroom unit and a foundation of a building in which the bathroom unit is installed protrudes below the floor, so that the above-mentioned drain gutter or the like cannot be attached. Therefore, the inventor of the present invention does not provide the drainage gutter as described above, makes the lower frame of the door waterproof, and provides a drainage hole on the bottom surface of the lower frame, and drains directly from the drainage hole. We thought that the above problem could be solved. However, even in the case of direct drainage in this way, the conventional drainage pipe has a problem that the elbow or the like is obstructed by a projecting part of the building and still cannot be piped well.

[0006]
