It is sufficient if the bathroom is provided so that the bathroom can be accessed directly from the aesthetic room.

(Embodiment) An embodiment of the bathroom structure according to the present invention will be described in detail below using the accompanying drawings.

1 to 4 show one embodiment of a bathroom structure according to the present invention. In these figures, the reference numeral 10 generally indicates the bathroom, and the bathroom 10 is located between the lower floor (-floor) and the upper floor ceiling (second floor ceiling), and between the lower floor and the upper floor ceiling. The upper and lower floor atriums are defined by four side walls that extend into the upper and lower floors.

The components constituting the bathroom 10 are made into parts as shown in FIG. 2, and the bathroom 10 is designed to be constructed as a knock-down, field-assembled unit.

The lower floor of the bathroom 10 is composed of a washing area pan 20, a bathtub pan 30, and a center pan 40.

The ceiling on the upper floor of the bathroom 10 has a ceiling panel 50 and a skylight window 6
0. The skylight sash 60 is composed of a sash that can be opened and closed for ventilation in addition to lighting.

Among the four side walls of the bathroom IO, three side walls including the indoor side are composed of a plurality of wall panels 70, a decorative cover panel 72, etc., and one side wall facing outdoors is continuous with the lower and upper floors. It is composed of continuous satsushes 80 extending from upper to lower floors. The upper and lower floor continuous sashes 80 may be fitted with transparent glass or frosted glass for daylighting, and may be provided with blinds or the like as necessary.

Further, as shown in FIG. 3, an entrance 82 may be provided in the lower floor of the upper and lower continuous sash 80 for directly accessing the bathroom 10 from outside.

Incidentally, the side walls of the portions other than the upper and lower floor continuous satsushes 80 may be constructed by a conventional construction method instead of the unit construction method using the wall panels 70 and the like.

On the indoor side wall of the bathroom 10, access lowers 4.76 for the bathroom 10 are provided on the lower and upper floors, respectively. The entrance/exit lower 4 on the lower floor opens to a part where a washing area pan 30 is installed in the bathroom 10.

An internal balcony 78 is provided in the upper floor where the entrance/exit door is installed, and extends into the bathroom IO, and a spiral staircase 90 erected from the center pan 40 is connected to the internal balcony 78. ing. spiral staircase 9
0 connects the entrance/exit lower floor on the upper floor and the lower floor through an internal balcony 8.

Further, a body shower panel (shower core) 100 is arranged below the internal balcony 78 on the lower floor adjacent to the bathtub pan 20.

The washing area pan 20 constitutes a washing area 22 that curves in an arc to extend around the spiral staircase 90 on the side of the entrance/exit 47, and the washing area 22 has one end connected to the entrance/exit lower 4 of the lower floor.

4, and a drainage slope is set toward the drainage hole 24 from the side of the connection end with the entrance/exit lower 4.

This draining slope is set to about 1150 for boat fishing, in order to prevent washing water or overflow water from the bathtub 32 from flowing out of the bathroom from the inlet/outlet lower 4.
As mentioned above, since it extends in an arc shape on the side of the connecting end with the access lower 4 and the connecting end with the bathtub pan 30 having the drain hole 24, it extends along one side wall of the bathroom 10. This is due to the fact that the total length of the washing area 22 is longer than in the case where the washing area 22 extends in a straight line, and this reduces the risk of water flowing out of the bathroom from the entrance/exit lower 4 through the washing area 22. The drainage slope of this washing area 22 is set to be gentler than the conventional one in order to improve the safety of bathing (see FIG. 5).

A shelf 26 on which bathing accessories and the like can be placed is provided at a corner of the washing area pan 22 on the opposite side from the entrance/exit lower 4, and a faucet 28 is provided on the shelf 26.

The floor surface Fs of the washing area 22 and the floor surface Fb of the washing area 22 are configured in a straight line without any difference in level. As a result, even infants and elderly people can enter and exit the bathroom 10 more safely than before, and can also easily take a bath in a wheelchair. The bathtub pan 30 constitutes a bathtub 32, and the bathtub 32 extends in an arc shape around the spiral staircase 90 on the opposite side from the entrance/exit lower 4. The bathtub 32 is an inclined bathtub that gradually becomes deeper as it moves away from the washing area 22, that is, toward the shower core 100. The bathtub 32 has a depth of a normal bathtub on the deep side, that is, on the side of the shower core 100.
For example, it has a depth of about 550 mm, and the shallow side has a depth of about 200 mm.
It is sufficient if the depth is approximately the same. As a result, the washing area 22
The person can easily enter and exit the bathtub 32 without having a large step.

In order to provide the above-mentioned difference in depth at both ends of the bathtub 32, the bottom surface of the bathtub has a slope.
2 extends in an arcuate manner, so its total length is longer than if it were provided in a straight line along one side wall of the bathroom, and accordingly the bottom of the bathtub was The slope has become gentler, and the bathtub capacity has also been expanded.

A hot water supply hole 34 and a hot water spout hole 3 are provided on the deep side of the bathtub 32.
