To prevent the bathroom drainage from overflowing to the floor pan 2 for washing, and the bathroom drainage once fixed on the upper surface of the bath pan 1 for bathtubs is a small amount of the floor pans 1 for bathtubs. The structure is such that water can be quickly drained from the drain hole 7 to the main drain pipe 6 of the floor pan 2 for the washing place via the pipe material 8. Then, the drainage groove portion 4 of the floor pan 2 for the washing place can be made to function as a portion for collecting the bathroom drainage used in the washing place D, which is a relatively small amount of the bathroom drainage, and the capacity of the drainage groove portion 4 can be reduced. That is, since the groove can be formed so as to have a shallow depth, there is an advantage that the drain groove 4 can be formed to be easy to clean. Furthermore, if it says, the part other than the weir part 5 of the floor pan 1 for bathtub installation, ie, the bathtub mounting part 16, will be the drain groove part 4.
It has the advantage that it can be positioned lower than the above, and the spanning dimension F of the bathtub C can be reduced.

In addition, even if there is a small doorway etc. in the building leading to the bathroom which is the construction site, it is possible to carry into the bathroom for each constituent of the bathroom floor pan and to carry the bathroom floor pan into the bathroom without any trouble, Each component of the bathroom floor pan can be placed in the bathroom,
In other words, the construction work can be performed while ensuring a working space in the bathroom, and the placement and installation of the bathroom floor pan in the bathroom can be easily performed, and it can be positioned lower than the wash floor pan. Since the edge on the bathtub side of the floor pan for the washing room is stacked on the floor pan for bathtub placement with the stacking margin being variable, a bathroom unit as wide as possible can be formed for the floor plan of the bathroom. And, in addition,
The size of the span of the bathtub can be made smaller than the actual height of the bathtub, and the bathroom drainage is collected by the bathtub placement floor pan located at a lower position than the washroom floor pan so that the bathroom drainage is the washroom floor pan. It is possible to avoid overflowing to the top, and a lid material that is substantially flush with the upper surface of the floor pan for washing place is attached to the upper surface of the floor pan for bath placing adjacent to the edge of the floor pan for washing place adjacent to the bathtub. Since it is arranged, it is possible to take up a large washing area in the bathroom.

Further, in the bathroom floor pan according to the second aspect of the present invention, the bathroom floor pan is composed of the bathtub floor for placing the bathtub and the floor pan for forming the washing floor, so that the building leading to the bathroom, which is the construction site, is constructed. Even if there is a small doorway inside, each component of the bathroom floor pan can be brought into the bathroom so that the bathroom floor bread can be carried into the bathroom without any trouble. That is, the construction work can be performed while ensuring a working space in the bathroom, and the placement and installation of the bathroom floor pan in the bathroom can be easily performed. Since the drain groove that is recessed below the floor pan for bathtub placement is formed at the edge on the side, bathroom drainage is collected in the drain groove to avoid overflowing of bathroom drainage to the upper surface of the floor pan for washing area. And in addition, this Since the edge of the washing floor side of the bathtub floor pan was stacked on the water groove part with the stacking margin being variable, the bathroom floor pan can be installed exactly according to the floor plan of the bathroom. It is possible to form a bathroom unit that is as wide as possible for the floor plan, and the flush pan that is not flush with the edge of the floor pan for bathtub placement that does not overlap the edge of the floor pan for bathtub placement is approximately flush with the top surface of the floor pan for bathtub placement. Since the continuous lid material is disposed in the bathroom, a large area for placing the bathtub in the bathroom can be obtained, and a large-capacity bathtub can be installed in the bathroom.

Further, in the bathroom floor pan according to the third aspect of the present invention, since the bath floor pan comprises the bathtub floor pan on which the bathtub is placed and the washroom floor pan which constitutes the washroom, the bathroom floor at the construction site is reached. Even if there is a small doorway in the building, each component of the bathroom floor pan can be brought into the bathroom so that the bathroom floor bread can be carried into the bathroom without any trouble. It can be placed in the bathroom, that is, the construction work can be performed while securing a working space in the bathroom, and the placement and installation of the bathroom floor pan in the bathroom can be easily performed. A drain groove that is recessed downward is formed at the edge of the bathtub side, and a weir portion that rises upward is provided at the edge of the floor pan for bathtub placement on the washbasin side. The weir section of the floor pan for placing is made variable in the stacking allowance. Since they are stacked, the bathroom floor pan can be installed exactly according to the floor plan of the bathroom, and a bathroom unit as wide as possible can be formed with respect to the floor plan of the bathroom. It is possible to equip the bathroom floor pan with a function of blocking the bathroom drainage that has fallen on the floor with a weir to prevent the bathroom drainage from overflowing onto the floor pan for the washroom. In addition, a main drainage pipe for draining the bathroom drainage to the outside of the bathroom is opened in the drainage groove, and a small drainage hole for draining the bathroom drainage is formed on the upper surface of the floor pan for bathtub placement. Since the drainage pipe is in communication with the drainage pipe, the bathroom drainage blocked by the weir on the upper surface of the bathtub floor pan is drained from the small drainage hole of the bathtub floor pan through the pipe material to the main drainage of the floor pan for the washroom. The bathroom floor pan can be equipped with the function of quickly draining the pipe. Therefore, by adopting this structure for the bathroom floor pan, it does not affect the drainage function of the bathroom drainage of the bathroom floor pan, and even with the structure in which the bath floor floor pan is stacked on the wash floor floor pan, Since the portion of the floor pan for bathtub placement other than the weir portion, that is, the part on which the bathtub is placed can be located at a position lower than the drainage groove of the floor pan for washroom, it is possible to reduce the span dimension of the bathtub. Yes, and
Since the drainage groove of the floor pan for the washroom serves as a water collecting area for only the bathroom drainage used in the washroom, the depth of the drainage groove can be made shallow so that cleaning or the like can be performed easily. In addition, a lid material that is substantially flush with the top surface of the floor pan for the washing place is placed in the drainage groove of the floor pan for the washing place that does not overlap the weir of the floor pan for placing the bathtub, so the washing area of the bathroom can be reduced. Can be big.
