2. Description of the Related Art With the advent of an aging society, there has been a demand for a bathroom in which a bather can freely come in and out without having to worry about his / her feet by eliminating a step between floors between a bathroom washroom and a dressing room. ing. For this purpose, it is necessary to eliminate the step between the floor of the bathroom washing area (hereinafter referred to as the washing scene) and the floor of the entrance / exit, but this causes the drainage in the bathroom to pass through the entrance / exit and undress. It is necessary to form a groove for drainage in front of the entrance / exit of the washing place so as not to flow out to the room side, and to cover this groove with a groove lid (for example, grating) having a drainage inflow section.

FIG. 5 shows a waterproof floor pan of a bathroom unit forming such a bathroom. This waterproof floor pan 100
At the outer peripheral portion surrounding the bathtub placement part 111 for installing the bathtub and the washbasin part 112 forming the washbasin A, a wall mounting part 113 for installing a wall panel is formed to be higher, and at the washbasin part 112 side. A door frame installation section 114 is formed at a position where the wall mounting section 113 of the door frame is cut out.
Groove 112a for drainage on the side of the washing section 112 along 14
Are formed. Therefore, as shown in FIG.
By covering the groove portion 112a with the grating 120 and installing the door frame 121 in the door frame installation portion 114, the washing area 1
The washing scene P of 12 and the upper surface of the lower frame portion 121a of the door frame 121 can be formed without any step, and the drainage on the side of the washing place A can be passed through the grating 120 without flowing out to the lower frame portion 121a side of the door frame 121. Can be poured into the groove 112a.

However, since the entrance / exit of the bathroom needs to be provided at various positions according to the floor plan of the building, for example, the waterproof floor pan 1 shown in FIG.
In 00, it is necessary to provide an entrance / exit at the position indicated by the arrow. In this case, since the waterproof floor pan is generally formed by resin molding using a molding die, the molding die needs to be changed if the position of the entrance / exit portion is different. Therefore, in this waterproof floor pan 100, an expensive molding die is used for this production.
Alternatively, it is necessary to use four types, and there is a problem that the cost is too high.

In this case, it is conceivable to cut the wall mounting portion 113 and attach the door frame installation piece to it, but this requires cutting work and attachment work, so the cost of these works The up is also big.

On the other hand, in order to make one molding die, FIG.
As shown by, the washing area 112 of the waterproof floor pan 101
A groove 112a for drainage is formed on the entire outer periphery of the wall mounting portion 113 which also serves as a door frame installation portion 114, as shown in FIG.

In this waterproof floor pan 101, the washing place 11
The entrance / exit can be formed on any side of 2, but the washing area 11
It is necessary to cover the entire groove 112a formed around the groove 2 with a groove lid such as the grating 120, and various problems due to this groove lid occur. That is, the groove lid (grating 120) having the drainage inflow portion is easily soiled and heavy and difficult to handle. Therefore, if the groove lid increases, cleaning of the bathroom becomes difficult.
Further, since the groove lid (grating 120) is apt to be deformed or rattling when stepped on with a foot, if the groove lid (grating 120) is increased, the usability in the bathroom may be deteriorated. Further, there is a problem that the bather feels the washing space A is narrow due to the groove cover (grating 120).

In view of the above points, the present invention makes it possible to easily form an entrance / exit portion having no step with respect to the washing scene of the washing place at any position on the washing place side, and keep the manufacturing cost low. It is an object of the present invention to provide a waterproof floor pan that can be formed and does not cause a problem due to the groove lid.
