In addition, the installation level of the floor panel 16 of the washroom 3 is set to be higher than the floor of the shower room 2, and an inter-room joint component 27 (refer to Fig.10 ).

[0076] Figure 4AThe state shown in (b) is a state where a skirting board 20 as one of the panel fixing components is fixed to the floor end of the floor panel 16 after the floor panel 16 is manufactured. The position where the skirting board 20 is fixed is the position where the washroom side wall panel 10 is erected. That is, the skirting board (panel fixing component) 20 for fixing the washroom side wall panel 10 is fixed to the floor end except for the position where the door 6 as the entrance and exit to the shower room 2 and the position where the inlet opening 11 as the entrance and exit to the sanitary unit structure 1 having the shower room 2 and the washroom 3 is formed.

[0077] A washroom panel locking member 23 is mounted on the skirting board 20 in order to vertically set the washroom side wall panel 10. The washroom panel locking member 23 has a structure in which the lower end portion of the washroom side wall panel 10 is fitted and tightly connected to vertically set the washroom side wall panel 10. In addition, the adjacent washroom side wall panels 10 are structured to be fitted (matched) with respect to the joint portion 25 vertically set on the skirting board 20 and joined.

[0078] Figure 4B (c) shows that a wash panel locking member 23 is provided on the skirting board 20 fixed to the floor panel 16 (see Figure 6 ), the state where two washroom side wall panels 10 are vertically arranged. Figure 4B (d) shows a state where the entire washroom side wall panel 10 constituting the washroom 3 is vertically installed. Figure 4B (e) means from Figure 4B The state shown in (d) is a state where the washroom ceiling wall panel 13 is installed.

[0079] As described above, after the shower room 2 is completed, the washroom 3 is made to complete the washroom space. That is, the construction process of the washroom 3 includes the following steps.

[0080] (5) The floor panel 16 of the washroom 3 is cut into a desired size, and the cut floor panel 16 is supported by a plurality of supporting legs 18 so as to have a height corresponding to the floor level of the shower room 2, thereby producing a double floor.

[0081] (6) The skirting board 20 is provided at a predetermined position of the floor panel 16 of the bathroom 3 .

[0082] (7) The washroom panel locking member 23 is provided on the skirting board 20, and the washroom side wall panel 10 is provided upright. At this time, the lower end portion of the washroom side wall panel 10 is engaged (matched) with the washroom panel locking member 23, and the adjacent washroom side wall panels 10 are engaged with the joint portion 25 as a wall column provided upright therebetween to be fixed to each other. Alternatively, a structure in which the adjacent washroom side wall panels 10 are directly engaged with each other may be adopted.

[0083] (8) The washroom ceiling wall panel 13 is attached to the washroom side wall panel 10, and the washroom 3 is completed. As a result, the shower room 2 and the washroom 3 are completed, and the sanitary unit structure 1 is completed. As the washroom side wall panel 10, various shapes and styles with different widths are prepared in advance, and a desired shape and style is selected according to the position (length) to be erected on the floor panel 16. In addition, the washroom side wall panel 10 can also be configured to be cut into a desired width size as needed.

[0084] In addition, various appliances inside the shower room 2 and the washroom 3 are installed after the sanitary unit structure 1 is completed. Various appliances and drainage equipment are installed using the openable and closable openings such as the shower inspection port 14 of the shower ceiling wall panel 12, the washroom inspection port 15 of the washroom ceiling wall panel 13, and the under-floor inspection port 29.

[0085] In the above-mentioned construction process, the installation of the shower ceiling wall panel 12 and the washroom ceiling wall panel 13 shown in (4) and (7) can also be performed simultaneously in the final process.

[0086] In the construction of the sanitary unit structure 1, the following steps are performed in order: (a) installation of the floor base (waterproof base) 17 of the shower room 2, (b) installation of the shower side wall panel 9 of the shower room 2, (c) installation of the door frame 22 of the shower room 2 (determination of the horizontal reference of the washroom), (d) installation of the shower ceiling wall panel 12 of the shower room 2, (e) installation of the floor panel 16 of the washroom 3 (installation of the double floor), (f) installation of the skirting board 20 of the washroom 3, (g) installation of the washroom side wall panel 10 of the washroom, and (h) installation of the washroom ceiling wall panel 13 of the washroom 3. In addition, the installation of the shower ceiling wall panel 12 of (d) may be performed in the same process as the washroom ceiling wall panel 13 of (h).

[0087] In the construction of the sanitary unit structure 1 of the first embodiment, since the structure is as follows: the washroom 3 with the optimal size is made to match the installation space surrounded by the structural floor (thick plate), structural wall, and structural ceiling of the building (house), so the process of cutting the floor panel 16 of the washroom 3 into a desired shape is included. In addition, the following operations are generated: the cut floor panel 16 is installed to match the installation level of the shower room 2, and the skirting board 20 for vertically installing the washroom side wall panel 10 is fixed at a predetermined position on the installed floor panel 16. Since the production operation of such a double floor (including the floor panel 16 and the skirting board 20) is different from the assembly operation of the shower room 2 for which the assembly parts are prepared in advance, and the assembly operation of the washroom side wall panel 10 and the washroom ceiling wall panel 13 in the washroom 3, the construction personnel are often different. Therefore, when a large number of sanitary unit structures 1 are installed in a building such as a collective housing, the following construction method is used: a construction worker on one side assembles the shower room 2 in sequence, and a worker on the other side installs a double-layer floor (16, 20) having a desired size adjacent to the assembled shower room 2. After the installation of the double-layer floor is completed, the construction worker who has completed the assembly of the shower room 2 assembles the washroom side wall panel 10 and the washroom ceiling wall panel 13 prepared in advance on the double-layer floor. In this way, when a plurality of sanitary unit structures 1 are installed, it is a structure that can be effectively promoted by different construction workers.

[0088] As described above, in the construction of the sanitary unit structure 1 of the first embodiment, although the toilet 3 having the optimum size is produced to match the installation space in the building (house), the construction is easy and the construction time can be greatly shortened.

[0089] Figure 5 This is a diagram showing a panel locking member 21 for fixing the shower side wall panel 9 of the shower room 2 to the floor base 17 in the sanitary unit structure 1 according to the first embodiment. Figure 5 A part of the outer surface of the shower room 2 is shown in an enlarged manner. In addition, after the shower room 2 is installed inside the installation space, the outer surface of the shower room 2 cannot be seen by the user.

[0090] like Figure 5As shown, a joint portion 24 serving as a wall column is provided between adjacent shower side wall panels 9, and the adjacent shower side wall panels 9 are held mutually and arranged upright by the joint portion 24. A joint locking tool 21a of the shower panel locking member 21 is mounted on the lower end portion of the joint portion 24. The joint locking tool 21a fixes the outer edge of the floor base (waterproof base) 17 of the shower room 2 by clamping it from above. As a result, the joint portion 24 of the shower room 2 is reliably fixed to the floor base (waterproof base) 17 and arranged upright. In addition, the support leg 18 disposed directly below the joint portion 24 can also be made of a material having higher rigidity than the support leg 18 disposed in other areas.

[0091] A panel locking tool 21b of a shower panel locking member 21 is mounted on the lower end portion of the shower side wall panel 9. The panel locking tool 21b fixes the outer edge of the floor base (waterproof base) 17 of the shower room 2 by clamping it from above. In addition, the lower end of the shower side wall panel 9 is formed of a metal plate bent into a U-shape, and the U-shaped portion is inscribed in the floor base (waterproof base) 17 and is retained. As a result, the shower side wall panel 9 of the shower room 2 is erected in a state of being reliably fixed relative to the floor base (waterproof base) 17. In addition, the shower side wall panel 9 has a structure in which it is erected relative to the floor base 17 as a waterproof base by a panel fixing member including the shower panel locking member 21 and the joint 24.

[0092] Figure 6 This is a diagram showing a washroom panel locking member 23 for fixing the washroom side wall panel 10 of the washroom 3 to the skirting board 20 of the floor panel 16 in the sanitary unit structure 1 of the first embodiment. Figure 6 A part of the outer surface of the toilet 3 is shown in an enlarged manner. In addition, similarly to the shower room 2, after the toilet 3 is installed inside the installation space, the outer surface of the toilet 3 cannot be seen by the user.

[0093] like Figure 6 As shown, a joint portion 25 as a wall column is provided between adjacent washroom side wall panels 10, and the adjacent washroom side wall panels 10 are held mutually and erected by the joint portion 25. A joint locking tool 23a of the washroom panel locking member 23 is installed at the lower end portion of the joint portion 25. The joint locking tool 23a is fixed to a wall-mounted guide rail 26 integrally formed with the upper surface of the skirting board 20 on the floor panel 16 in a manner of being loaded and clamped from above. The wall-mounted guide rail 26 has a guide rail 26a protruding upward and extending in the longitudinal direction, and is a structure in which the joint locking tool 23a clamps the guide rail 26a.

[0094] In addition, the skirting board 20 and the wall-mounted guide rail 26 may be configured by different components and fixed to each other. In addition, the skirting board 20 may be configured to have only the wall-mounted guide rail 26, for example, a structure in which a plate (guide rail 26a) extending in the longitudinal direction is protruding from the center of a flat plate extending in the longitudinal direction on the floor panel 16 in an inverted T shape. In addition, aluminum is used as the material of the skirting board 20 in Embodiment 1, but in the present invention, the material of the skirting board 20 is not specifically aluminum.

[0095] In this way, the washroom side wall panel 10 is placed and fixed on the skirting board 20, and the engaging and locking tools 23a clamp the guide rails 26a, so that the engaging portion 25 of the washroom 3 is reliably fixed at a predetermined position relative to the skirting board 20 of the floor panel 16 and is vertically arranged. In addition, the support leg 18 disposed directly below the engaging portion 25 can also be made of a material having higher rigidity than the support leg 18 disposed in other areas.

[0096] The panel locking tool 23b of the washroom panel locking member 23 is mounted on the lower end portion of the washroom side wall panel 10. The panel locking tool 23b is fixed to the wall-mounted guide rail 26 provided on the upper surface of the skirting board 20 in a manner of being placed and clamped from above. In addition, the lower end of the washroom side wall panel 10 has the same structure as the lower end of the shower side wall panel 9, and is formed by a metal plate bent into a U shape. Therefore, the U-shaped portion is internally connected to the wall-mounted guide rail 26 on the upper surface of the skirting board 20 and is retained. Therefore, the washroom side wall panel 10 has a structure fixed to the wall-mounted guide rail 26 provided on the upper surface of the skirting board 20, similarly to the shower side wall panel 9. As a result, the washroom side wall panel 10 of the washroom 3 is reliably fixed relative to the floor panel 16.

[0097] The structure of the first embodiment has a structure in which the washroom side wall panel 10 can be erected relative to the floor panel 16 by the panel fixing member including the skirting board 20 , the washroom panel locking member 23 , the joint 25 , and the wall-mounted rail 26 .

[0098] In addition, various fixing means can be applied to the erection structure of the shower side wall panel 9 and the wash side wall panel 10 as long as the respective panels can be reliably erected. In the present invention, at least the lower end portions of the shower side wall panel and the wash side wall panel are panel structures having the same structure, the shower side wall panel has a structure that is erected from a floor base as a waterproof base by using a shower panel locking member (21), and the wash side wall panel has a structure that is erected from a floor panel as a double floor by using a wash panel locking member (23).

[0099] In the structure of the first embodiment, the connection at the corner portion (right angle portion) of the skirting board 20 on the floor panel 16 has a structure in which the skirting board 20 can be connected at a right angle using corner parts (30, 31) to ensure safety for the user.

[0100] Figure 7 It is a perspective view showing the convex corner member 30 and the concave corner member 31 . Figure 7 This is a diagram viewed from the bathroom space side (front side) which is the inner side of the bathroom 3. Figure 7 In the figure, the left side shows a convex corner member 30 for joining the convex skirting board 20 bent at a right angle, and the right side shows a concave corner member 31 for joining the concave skirting board 20 bent at a right angle. Figure 7 As shown, the protruding corner member 30 and the recessed corner member 31 are respectively provided with insertion engaging portions 30a and 31a protruding in the direction in which the skirting board 20 is arranged. Although the protruding corner member 30 and the recessed corner member 31 of the first embodiment are described by using an example of a resin material that is easy to process and strong, the present invention is not limited to the resin material, and various materials that can be processed can be used.

[0101] Figure 8 30 and the recessed corner member 31 are respectively connected and fixed to the skirting board 20. Figure 8 The washroom side wall panel 10 is vertically arranged above the skirting board 20 shown. Fig. 9 20 is a cross-sectional view of the skirting board 20, which is a cross-sectional view obtained by cutting in a direction perpendicular to the longitudinal direction. Fig. 9 As shown, a hollow portion 20a is formed in the wooden foundation beam (foundation) portion where the wall-mounted guide rail 26 is protrudingly provided on the skirting board 20. In addition, a flat foot portion 20b is protrudingly provided in the horizontal direction at the lower end of the hollow portion 20a, and the skirting board 20 is stably arranged on the floor panel 16 by providing the foot portion 20b.

[0102] As described above, the baseboard 20 is provided with the hollow portion 20a, and the insertion joint portions 30a, 31a of the convex corner member 30 and the concave corner member 31 are inserted and joined in the hollow portion 20a. The spatial shape of the hollow portion 20a and the protruding shape of the insertion joint portions 30a, 31a are corresponding shapes, and the insertion joint portions 30a, 31a are configured to fit (match) with the hollow portion 20a. As a result, the baseboard 20 is reliably joined at the right angle portion, and the sharp edge portion can be removed at the right angle portion, which is a structure with high safety for users who use the bathroom 3.

[0103] Fig.102 is a diagram showing an inter-room joint component 27 connecting the floor of the shower room 2 and the floor of the washroom 3. The inter-room joint component 27 is a component disposed on the lower side of the door 6, and is disposed obliquely in such a manner that the level L1 of the floor of the shower room 2 is lower than the level L2 of the floor of the washroom 3. By providing the inter-room joint component 27 on the lower side of the door 6 as the entrance and exit, it is possible to prevent water from flowing from the shower room 2 to the washroom 3, and to make it easier for people to enter and exit, thereby achieving a safer structure. In addition, it is possible to ensure that a certain distance can be reliably maintained between the shower room 2 and the washroom 3 at all times.

[0104] As described above, after the frame as the outer side of the shower room 2 and the washroom 3 is completed, the sanitary ware and spare parts in each room are equipped to the specified position. In particular, in the case of a structure in which a heavy sanitary ware is fixed to the wall, for example, when the washstand 7 is fixed to the washroom 3, it is preferably set on the joint (24, 25) of the wall column as the wall surface. When the washstand 7 is set in this way, even if a large load is applied to the washstand 7, the load can be borne on the rigid joint 25, which can reduce the deflection of the washroom side wall panel 10.

[0105] In addition, as mentioned above Figure 2 As shown in the stereoscopic view, in the sanitary unit structure 1 of the first embodiment, inspection ports (14, 15) are provided on the ceiling wall panels (12, 13) of the shower room 2 and the washroom 3, respectively. The shower inspection port 14 is provided near the entrance and exit (the location where the door 6 is arranged) of the shower room 2 of the shower ceiling wall panel 12. In addition, the washroom inspection port 15 is provided near the entrance and exit (the location where the door 6 is arranged) of the shower room 2 of the washroom ceiling wall panel 13. That is, the shower inspection port 14 and the washroom inspection port 15 are provided on both sides of the entrance and exit of the shower room 2 in the respective ceiling wall panels (12, 13). In this way, by providing the shower inspection port 14 and the washroom inspection port 15 near the entrance and exit (the location where the door 6 is arranged), a certain degree of space is ensured because there is no large-scale equipment at the entrance and exit, so the maintenance and management workability performed by means of the inspection ports (14, 15) is better.

[0106] As described above, in the sanitary unit structure 1 of the first embodiment, the side walls of the washroom 3 are formed by connecting a plurality of side wall panels (10), and the ceiling wall is formed by connecting a plurality of ceiling wall panels (13). Figure 1 and Figure 2 As shown, the joint 25 connecting the plurality of washroom side wall panels 10 and the joint 28 connecting the plurality of washroom ceiling wall panels 13 (see Figure 2) are arranged in a manner corresponding to the side wall and the ceiling wall of the washroom 3. That is, the joints (25, 28) are arranged in a manner continuous at the side wall and the ceiling wall of the washroom 3. By making the joints (25, 28) continuous in this way, the strength of the panel structure of the washroom 3 is further enhanced, thereby achieving a structure that can ensure a higher strength as the sanitary unit structure 1.

[0107] (Implementation Method 2)

[0108] Next, refer to the attached Figure 1 A sanitary unit structure and a construction method thereof according to a second embodiment of the present invention will be described. Fig.11 It is a side view showing an example of the internal structure of the shower room 2 and the washroom 3 constituting the sanitary unit structure 1 of the second embodiment of the present invention, showing the state after the side wall (wall panel) of each front side is removed. In the description of the sanitary unit structure and its construction method of the second embodiment, the same reference numerals are given to the elements having substantially the same functions and structures as the above-mentioned first embodiment. In the sanitary unit structure and its construction method of the second embodiment, the difference from the sanitary unit structure and its construction method of the first embodiment is that the washroom 3 and the shower room 2 are both waterproof floor structures. The other points of the second embodiment are the same as those of the first embodiment, so the points different from the first embodiment are mainly described in the second embodiment.

[0109] like Fig.11 As shown, the sanitary unit structure 1 of embodiment 2 has the same structure as that of embodiment 1, and a washroom 3 is provided adjacent to the shower room 2, and is constructed with dimensions (external shape) corresponding to the installation space surrounded by the structural floor (thick plate), structural walls, and structural ceiling in a residential building.

[0110] In the sanitary unit structure of the second embodiment, similarly to the structure of the first embodiment, the side walls of the shower room 2 and the washroom 3 are also formed by assembling a plurality of panels having the same structure and have the same upright structure.

[0111] Fig.12 and Fig.11 Similarly, it is a side view showing an example of the internal structure of the shower room 2 and the toilet room 3 constituting the sanitary unit structure 1 of the second embodiment. Fig.12 The structure of the floor panel 50 of the washroom 3 is partially shown. Fig.12 As shown, the toilet drain port 42 is provided on the floor panel 50 of the toilet 3. That is, the toilet 3 of the second embodiment is waterproofed similarly to the shower room 2, and the floor panel 50 of the toilet 3 is composed of a waterproof panel.

[0112] The floor panel 50 is formed to have a drainage slope so that the drainage port 42 is at the lowest level on the floor panel 50. The floor panel 50 may have a water return structure to prevent water from leaking from under the door when cleaning the floor.

[0113] The floor panel 50 of the washroom 3 is similar to the structure of the first embodiment and is supported by a plurality of support legs 18 on the structural floor (thick board) with a predetermined space. Fig.12 As shown, the floor panel 50 has a reinforcing frame (e.g., a metal angle steel frame) 55 supported by the supporting legs 18, a reinforcing component (e.g., a plate) 54 placed on and fixed to the reinforcing frame 55, a waterproof layer (e.g., a waterproof-treated material such as a cement board or wood fiber cement board) 53 placed on and fixed to the reinforcing component 54, and a floor tile layer 52 serving as a decorative panel constituting the floor of the bathroom 3.

[0114] The structure of the floor panel 50 of the washroom 3 of the second embodiment has a structure that can be easily changed to become the optimal size and shape corresponding to the installation space surrounded by the structural floor (thick plate), structural wall, and structural ceiling in the residence as a building. That is, the reinforcement frame 55 of the floor panel 50 is a metal frame frame material that can be easily cut corresponding to the installation space, and is pre-composed of a square frame material. In addition, the reinforcement component 54 is composed of a plate material such as wood that can be easily cut. Furthermore, the waterproof layer 53 is a material that can be waterproof and can be easily cut and processed, such as a cement board or a wood fiber cement board. As a floor tile layer 52, it is a waterproof floor tile floor, which can be a structure that is pre-matched to the floor shape of the washroom 3 and cut, or a structure that is covered with multiple floor tile panels (waterproof treatment). In addition, the floor panel 50 of the washroom 3 is a structure without an inspection port.

[0115] In the shower room 2 of the second embodiment, as in the first embodiment, the floor may be formed by the waterproof base 17 supported by a plurality of support legs 18 with a predetermined space relative to the structural floor (thick board). Alternatively, as the floor of the shower room 2, as in the case of the washroom 3, a floor panel 51 may be provided on the waterproof base 17. The floor panel 51 of the shower room 2 may also be a structure similar to the floor panel 52 of the washroom 3.

[0116] (Implementation 3)

[0117] Next, refer to the attached Figure 1 A sanitary unit structure and a construction method thereof according to a third embodiment of the present invention will be described. Fig.13It is a side view showing an example of the internal structure of the shower room 2 and the washroom 3 constituting the sanitary unit structure 1 of the third embodiment of the present invention, showing the state after the side wall (wall panel) of each front side is removed. In the description of the sanitary unit structure and its construction method of the third embodiment, the same reference numerals are given to the elements having substantially the same functions and structures as the first and second embodiments described above. In the sanitary unit structure and its construction method of the third embodiment, the difference from the sanitary unit structure and its construction method of the first embodiment is that a drain outlet is provided on the shower room side of the washroom 3. The other points in the third embodiment are the same as those in the first and second embodiments, so the points different from the first and second embodiments are mainly described in the third embodiment.

[0118] like Fig.13 As shown, the sanitary unit structure 1 of embodiment 3 has the same structure as that of embodiment 1, and a washroom 3 is provided adjacent to the shower room 2, and is constructed with dimensions (external shape) corresponding to the installation space surrounded by the structural floor (thick plate), structural walls, and structural ceiling in a residential building.

[0119] In the sanitary unit structure of the third embodiment, similarly to the structure of the first embodiment, the side walls of the shower room 2 and the washroom 3 are also formed by assembling a plurality of panels having the same structure, and have the same erection structure and construction method.

[0120] like Fig.13 As shown, the floor panel 50 of the washroom 3 of the sanitary unit structure of the third embodiment is provided with a drain port 62 for the washroom on the shower room side. The floor of the washroom 3 of the third embodiment is formed by the floor panel in the same manner as in the structure of the first embodiment. In addition, as for the floor of the washroom 3 of the third embodiment, the same waterproof treatment as in the shower room 2 can be applied to the floor panel 50 of the washroom 3 in the same manner as in the structure of the second embodiment, and the floor panel 50 of the washroom 3 can be formed by a waterproof panel.

[0121] Moreover, the floor panel 50 of the washroom 3 is supported by a plurality of supporting legs so as to have a predetermined space on the structural floor (thick board) in the same manner as the above-mentioned first and second embodiments, and has the same structure.

[0122] As described above, in the floor panel 50 of the washroom 3 of the third embodiment, a drain port 62 is provided near the boundary portion with the adjacent shower room 2. The position where the drain port 62 is formed in the floor panel 50 is the lowest level position, and has a drainage slope so that water in the floor panel 50 of the washroom 3 can reliably flow to the drain port 62. In addition, the floor panel 50 may also have a water return structure to prevent water from leaking from under the door when the floor is cleaned.

[0123] In addition, the formation position of the drain port 62 on the floor panel 50 of the washroom 3 is set at the entrance and exit side between the shower room 2 and the washroom 3, so that the water spilled when entering and exiting the shower room 2 can quickly flow to the drain port 62. Therefore, as the formation position of the drain port 62, it is preferably near the boundary portion with the adjacent shower room 2, and it can also be set at the corner portion of the side wall panel side of the floor panel 50.

[0124] The drainage slopes are formed so that the water falling on the floor panel 50 of the washroom 3 flows toward the drain port 62, and the water falling on the floor panel 51 of the shower room 2 flows toward the drain port 41. In addition, the installation level of the floor panel 51 of the shower room 2 is set to be lower than the ground of the floor panel 50 of the washroom 3, so that the water in the shower room 2 as a wet space does not flow into the floor panel 50 of the washroom 3.

[0125] Fig.14 Schematically shows the positional relationship between the arrangement level of the drain port 41 on the floor panel 51 of the shower room 2 and the arrangement level of the drain port 62 on the floor panel 50 of the washroom 3 according to the third embodiment. Fig.14 As shown, the drain port 62 of the washroom 3 is located at the lowest level of the floor panel 50 of the washroom 3, and the drain port 41 of the shower room 2 is located at the lowest level of the floor panel 51 of the shower room 2. In addition, a slope is provided so that the vicinity of the entrance and exit of the shower room 2 is the highest level position in the shower room 2. That is, in the shower room 2, the formation position of the drain port 41 is the lowest level position in the shower room 2, and the vicinity of the entrance and exit is the highest level position in the shower room 2.

[0126] In the third embodiment, by making the structure to improve the dryness of the bathroom 3, it is possible to use a material (wood or the like) that cannot be used as a floor panel of the bathroom 3 under normal circumstances.

[0127] Fig.13 The drain port 62 on the floor panel 50 of the washroom 3 shown in the figure is provided at the corner portion of the side wall panel side of the inner side of the toilet 8, but the present invention is not limited to this structure, and may also be provided at Fig.13 As the formation position of the drain port 62 of the third embodiment, it is preferable that it is at least in the floor panel 50 of the washroom 3, and is near the boundary between the shower room 2 and the washroom 3.

[0128] As described above, in the floor panel 50 of the washroom 3, since the drain port 62 is provided on the inlet and outlet sides between the shower room 2 and the washroom 3, water falling into the wet area at the boundary portion between the shower room 2 and the washroom 3 flows to the drain port 41 in the shower room 2, and flows to the drain port 62 closer to the wet space in the washroom 3. Therefore, the washroom 3 can keep almost the entire area as a dry space.

[0129] As described above, the sanitary unit structure of the present invention can provide residential equipment with a desired shower room and a washroom for installation spaces of different shapes in various residences of a building, as specifically described in Embodiment 1, Embodiment 2, and Embodiment 3. Therefore, according to the present invention, it is possible to provide a highly reliable equipment that can easily install a sanitary unit structure with a shower room and a washroom in accordance with the installation space.

[0130] The present invention has been described in the embodiments with a certain degree of detail, but the disclosure of the embodiments should be able to change the details of the structure, and the replacement, combination and change of order of the elements of the modified examples of the embodiments can be achieved without departing from the scope and concept of the present invention.
