The bathroom space S has a substantially rectangular shape that is long in one direction when viewed from above. The bathroom unit 1 is provided adjacent to the washroom W. The bathroom unit 1 forms a bathroom space S that is smaller than the space of the adjacent washroom W. Specifically, the bathroom space S according to this embodiment is a narrow space with a width of about 1200 mm, a depth of about 800 mm, and a height of about 2200 mm.

As shown in FIGS. 1 and 2, in the bathroom unit 1, a bathroom door 3 is provided on one of the four walls adjacent to the washroom W. In the following description, the wall surface on which the bathroom door 3 is provided will be referred to as wall surface E. The other wall surfaces of the bathroom unit 1 are denoted as wall surfaces A, B, and C, respectively, in a clockwise direction in a plan view based on the wall surface E on which the bathroom door 3 is provided. In the following description, "front" means the bathroom space S side with respect to the wall unless otherwise specified. The bathroom door 3 is an inward-opening door with a pivot shaft extending vertically on the wall A side. In the bathroom door 3, a translucent member is fitted into substantially the entire inside of the door frame. A fixed window 4 in which a transparent member similar to the bathroom door 3 is fitted is provided between the bathroom door 3 on the wall surface E and the wall surface C. That is, the opening when the bathroom door 3 is opened is formed at a position away from the wall surface C. In this embodiment, transparent glass is used as the light-transmitting material for the bathroom door 3 and the fixed window 4. The bathroom space S and the washroom W are provided so that one side can be viewed from the other through a bathroom door 3 and a fixed window 4.

As shown in FIGS. 2 and 3, a wall surface E and a wall surface B facing the wall surface E form two long sides of a rectangular shape in a plan view of the bathroom space S, respectively. A wall surface A and a wall surface C extending in a direction intersecting the wall surface E face each other and form two short sides of a rectangular shape in a plan view. An operating section 2A of the shower device 2 is arranged on the wall surface C. The shower head 2B of the shower device 2 is provided to hang down from a pipe that extends upward from the operating section 2A along the wall surface C and extends toward the opposing wall surface A along the ceiling surface 30A.

As shown in FIGS. 1, 2, and 3, the bathroom unit 1 includes a floor member 10, a plurality of (four in the figure) wall panels 21, 22, 23, 24, a ceiling panel 30, and a lighting device. It is equipped with 40. The floor member 10 is a member that forms a floor surface 10A of the bathroom space S. The floor surface 10A is sloped so that hot water flows toward a drain port (not shown).

As shown in FIG. 3, the plurality of wall panels 21, 22, 23, and 24 form wall surfaces E, A, B, and C of the bathroom space S, respectively. Each wall panel 21, 22, 23, 24 is arranged upright from the peripheral edge of the floor member 10 so as to surround the floor surface 10A. Among the plurality of wall panels 21, 22, 23, and 24, the wall panel 21 includes a bathroom door 3, a fixed window 4, a frame, and the like. The wall panels 22, 23, and 24 are formed by pasting plasterboard on the back side of a front panel made of steel plate. Among the wall panels 22, 23, and 24, each surface of the wall panel 22 forming the wall surface A and the wall panel 24 forming the wall surface C is formed of a uniform smooth surface. The surface of the wall panel 23 forming the wall surface B is formed in a different manner from the surfaces of the wall panels 22 and 24. The surface of the wall panel 23 is formed so that it becomes bright and dark when it receives illumination light from the lighting device 40.

The ceiling panel 30 is arranged above the plurality of wall panels 21, 22, 23, and 24, and forms a ceiling surface 30A of the bathroom space S (see FIG. 1). The ceiling panel 30, like the wall panels 22, 23, and 24, is formed by pasting a gypsum board on the back side of a front panel made of steel plate.

As shown in FIGS. 2 and 3, the lighting device 40 is placed at a corner of the wall. In the case of this embodiment, the lighting device 40 is installed at a corner BC between wall C and wall B among four corner parts EA, AB, BC, and CE formed by four walls E, A, B, and C. It is provided. Specifically, the lighting device 40 is provided at a corner BC of the wall C on the wall B side. The lighting device 40 has a light emitting surface 40A. The light emitting surface 40A is exposed to the bathroom space S. Specifically, the light emitting surface 40A is exposed to the bathroom space S without being hidden behind anything, so that the user of the bathroom unit 1 can see it no matter where he or she stands in the bathroom space S. The light emitting surface 40A extends vertically in a long shape from the floor surface 10A to the ceiling surface 30A. The lighting device 40 directly irradiates light onto the bathroom space S using the light emitting surface 40A. The light emitting surface 40A is substantially parallel to the wall surface C and extends in a direction substantially orthogonal to the wall surface B. Such light from the light emitting surface 40A is irradiated along the wall surface B from the wall surface C side. That is, the light from the lighting device 40 is irradiated onto the wall surface B along the wall surface B from the side of the wall surface B. The wall surface B irradiated with the illumination light appears brighter than the other wall surfaces E, A, and C.

The lighting device 40 is attached by sliding fitting to a frame 51, which will be described later. The lighting device 40 is attached to the frame 51 with the front light emitting surface 40A facing the bathroom space S side. When attached to the frame 51, the light emitting surface 40A of the lighting device 40 is substantially flush with the wall surface C. Note that "substantially the same surface" in the present disclosure is intended to include a case where there is a slight step difference of 5 mm or less between the light emitting surface of the lighting device and the wall surface, and does not mean completely identical surface. It is not intended only to make a face.

The lighting device 40 is formed to have a length that is 90% or more of the distance from the floor surface 10A to the ceiling surface 30A of the bathroom unit 1, that is, the height of the bathroom space S. Specifically, the lighting device 40 has a light emitting surface 40A having a length that is 90% or more of the height of the bathroom space S. Thereby, the lighting device 40 can irradiate illumination light over substantially the entire height of the bathroom space S.

As shown in FIGS. 4 and 5, the lighting device 40 includes a light source unit 41, a casing 42 that houses the light source unit 41, and is attached to the front side of the casing 42 with the front surface serving as a light emitting surface 40A. The light transmitting cover 43 is configured to include a light transmitting cover 43. Note that in FIG. 4, the lighting device 40 is shown with the light-transmitting cover 43 omitted. The lighting device 40 has a vertically elongated cylindrical shape by combining a housing 42 and a light-transmitting cover 43, and houses a light source unit 41 in its interior space. The light source unit 41 is fixed to the housing 42 with a plurality of clips 44.

The light source unit 41 has an elongated shape as a whole. As shown in FIG. 6, the light source unit 41 includes a substrate 41A, a plurality of LED chips 41B, and a frame 41C. The board 41A is a long flexible printed wiring board. The plurality of LED chips 41B are mounted on the substrate 41A in a line at predetermined intervals in the longitudinal direction. The frame 41C has a substantially U-shaped cross section with a groove formed therein. The substrate 41A is placed at the bottom of the groove of the frame 41C. The groove of the frame 41C is filled with a transparent potting agent 41D. As a result, the substrate 41A and the LED chip 41B are fixed to the frame 41C, and the substrate 41A and the LED chip 41B are waterproofed and insulated.

The housing 42 is formed by extrusion molding of aluminum. The housing 42 has a substantially uniform cross-sectional shape in the longitudinal direction. Specifically, as shown in FIG. 7, the casing 42 has a concave cross-section with an open front side. The housing 42 has a bottom plate portion 42A and a pair of side plate portions 42B. The bottom plate portion 42A is located at the rear end of the housing 42 when it is fixed to the frame 51 (see FIG. 5). The bottom plate portion 42A is formed into a flat plate shape extending parallel to the longitudinal direction and the left-right direction (width direction) of the housing 42. The pair of side plate portions 42B are formed such that their proximal ends are connected to both sides of the bottom plate portion 42A, and their distal ends extend in a direction away from the bottom plate portion 42A (forward). The pair of side plate portions 42B are each formed to have a crank-shaped bent cross section with a wider interval on the tip side (front side of the housing 42). The distal end surface of the side plate portion 42B is formed to be inclined toward the base end side as it goes toward the center side (inside) in the width direction of the housing 42.

As shown in FIG. 7, the housing 42 includes a holding portion 42C, an extending portion 42D, a rib portion 42E, a locking portion 42F, and an engaging portion 42G. A pair of the holding portions 42C, the extending portions 42D, the rib portions 42E, the locking portions 42F, and the engaging portions 42G are each provided in pairs symmetrically about the center of the housing 42 in the width direction. The pair of holding parts 42C are formed to protrude forward from the front surface of the bottom plate part 42A. The pair of holding parts 42C are provided at a predetermined distance from the center of the housing 42 in the width direction. A pair of holding parts 42C hold the light source unit 41. Specifically, the pair of holding parts 42C protrudes from the front surface of the bottom plate part 42A with a width slightly wider than the width of the light source unit 41. The light source unit 41 is fitted between the pair of holding parts 42C.

The pair of extending portions 42D are formed to extend outwardly from both sides of the bottom plate portion 42A. A plurality of cutout portions 42H are formed in each of the pair of extension portions 42D and are arranged in the longitudinal direction. When the housing 42 is attached to the frame 51, the engagement claws 51A on the frame 51 side engage with these notches 42H (see FIG. 5).

The pair of rib portions 42E are formed to extend outward from each outer surface of the pair of side plate portions 42B. The rear surface of the rib portion 42E comes into contact with the open end of the frame 51 when the lighting device 40 is fixed to the frame 51 (see FIG. 5). Each rib portion 42E is provided at a position closer to the rear end than the front end of the housing 42. The front end of the frame 51 comes into contact with the rib portion 42E when the housing 42 is attached to the frame 51. As shown in FIG. 5, when the lighting device 40 is placed on the wall surface C, the rib portion 42E forms the bottom of the joint between the lighting device 40 and the adjacent wall panels 23, 24, and is embedded in this joint. Receive silicone sealant SS.

The pair of locking portions 42F are formed to extend inward from each inner side surface of the pair of side plate portions 42B. A plurality of notches (not shown) are formed in the pair of locking portions 42F at a plurality of locations in the longitudinal direction. A clip 44 for fixing the light source unit 41 to the housing 42 is fitted into this notch.

The pair of engaging portions 42G are formed to extend forward from the front facing surface of each inner side surface of the pair of side plate portions 42B having a crank-shaped cross section. When the light-transmitting cover 43 is attached to the housing 42, an engaged portion 43B of the light-transmitting cover 43, which will be described later, engages with the pair of engaging portions 42G. The distal end of the engaging portion 42G is formed to protrude outward in the shape of a claw. The distal end of the engaging portion 42G engages with the distal end of the engaged portion 43B.

The light-transmitting cover 43 is formed by injection molding of resin. As shown in FIGS. 5 and 8, the light-transmitting cover 43, like the housing 42, has a substantially uniform cross-sectional shape in the longitudinal direction. The light-transmitting cover 43 has a concave cross-section with an open rear side. The light-transmitting cover 43 is attached to the housing 42 to form an internal space in which the light source unit 41 is housed together with the housing 42 . The transparent cover 43 made of resin is formed shorter than the housing 42 in consideration of the difference in thermal expansion with the housing 42 made of aluminum. Therefore, in the lighting device 40 in a normal state (normal temperature state), a gap is created between the upper and lower ends of the light-transmitting cover 43 and a lower cap 45 and an upper cap 46, which will be described later. This gap also functions as a water drain for removing moisture generated in the space between the transparent cover 43 and the housing 42 due to dew condensation or the like.

The light-transmitting cover 43 has light-transmitting properties. The light-transmitting cover 43 transmits light from the light source unit 41. The transparent cover 43 is non-transparent. When the transparent cover 43 is attached to the housing 42 , the internal space formed by the housing 42 and the transparent cover 43 is not visible from the front side of the transparent cover 43 .

As shown in FIG. 8, the transparent cover 43 has a front plate portion 43A and a pair of engaged portions 43B. The front plate portion 43A is located at the front end of the transparent cover 43 when it is attached to the housing 42. The front plate portion 43A is arranged at a predetermined distance from the bottom plate portion 42A of the housing 42 when the transparent cover 43 is attached to the housing 42. The front surface of the front plate portion 43A has a curved shape in which the center in the width direction is located slightly forward of the side edges. The front surface of the front plate portion 43A is a light emitting surface 40A of the lighting device 40. Both side edges of the front plate portion 43A are formed to be inclined in correspondence with the inclined surfaces at the tips of the side plate portions 42B of the housing 42.

The pair of engaged parts 43B are formed such that their proximal ends (front ends) are connected to the rear surface of the front plate part 43A, and their distal ends (rear ends) protrude rearward. The tip of each engaged portion 43B is formed to correspond to the claw-shaped portion at the tip of the engaging portion 42G. The tip of the engaged portion 43B is formed into a claw shape that projects inward. The pair of engaged parts 43B are respectively engaged with the pair of engaging parts 42G of the housing 42 when the transparent cover 43 is attached to the housing 42 (see FIG. 5). In this state, the seal member P1 is interposed in the gap between the pair of engaged parts 43B and the side plate part 42B of the housing 42. This ensures watertightness at the side edges between the transparent cover 43 and the housing 42.

As shown in FIG. 4, a lower cap 45 is provided at the lower end of the lighting device 40. The lower cap 45 is fixed to the lower end surface of the housing 42 by screwing from below. The lower cap 45 is formed in a step shape in which the width and front-to-back length on the upper end side are smaller than the width and front-to-back length on the lower end side. The lower cap 45 has a reduced upper end portion inserted into the space between the housing 42 and the transparent cover 43, and a lower end portion that extends downward so as to follow the external shapes of the housing 42 and the transparent cover 43. It is connected to the casing 42 in a so-called spigot shape that extends to the casing 42 . A water stop packing (not shown) is interposed between the lower cap 45 and the housing 42 in the connection direction (vertical direction). The lower end of the light source unit 41 is placed on the upper end of the lower cap 45 . A water stop packing P2 is interposed between the back surface (rear surface) of the transparent cover 43 and the lower cap 45.

As shown in FIG. 4, an upper cap 46 is provided at the upper end of the lighting device 40. The upper cap 46 is fixed to the upper end surface of the housing 42 by screwing from above. A lower end portion of the upper cap 46 is inserted into a space formed between the housing 42 and the light-transmitting cover 43. The upper cap 46 has a flat portion that contacts the upper end surface of the housing 42 , and a lower end portion that is inserted into the space between the housing 42 and the transparent cover 43 . A water stop packing P2 is interposed between the upper cap 46 and the back surface (rear surface) of the transparent cover 43. The upper cap 46 forms a through hole (not shown) that communicates the internal space and external space of the lighting device 40. This through hole is formed vertically through the upper cap 46 and functions as a wiring route for the light source unit 41.

Four pillar members 50 forming the frame of the bathroom unit 1 are erected at the four corners of the floor member 10 (see FIG. 5). A frame 51 is erected adjacent to one of the four pillar members 50. These pillar members 50 and frame 51 are each formed by bending a plate-shaped steel material. The frame 51 fixes the lighting device 40. The frame 51 is fixed to the column member 50 furthest from the bathroom door 3 among the two column members 50 located on the wall surface B side. As shown in FIG. 5, the frame 51 according to this embodiment is arranged adjacent to the wall C side of the column member 50.

As shown in FIG. 5, the frame 51 has a substantially U-shaped cross section with an open front surface. The frame 51 has an engaging claw 51A. A plurality of engagement claws 51A are provided in line in the longitudinal direction of the bottom surface of the frame 51. The engagement claw 51A is formed to protrude forward from the bottom surface of the frame 51 and extend in the vertical direction. The engaging claw 51A is inserted into a notch 42H formed in the extension 42D of the housing 42 of the lighting device 40, and fixes the lighting device 40. Specifically, the extending portion 42D contacts the bottom surface of the frame 51 together with the bottom plate portion 42A when the housing 42 is attached to the frame 51. An engaging claw 51A is inserted into each notch 42H from the rear side of the extension 42D. The length of each notch portion 42H in the longitudinal direction is longer than the vertical length of the engagement claw 51A. When the engaging claw 51A is inserted into the notch portion 42H and the entire lighting device 40 is slid downward, the engaging claw 51A engages with the extending portion 42D from below. In this way, the lighting device 40 is fixed to the frame 51 by the engagement between the notch 42H and the engagement claw 51A.

As described above, the light emitting surface 40A is arranged substantially on the same plane as the wall surface C. Specifically, in the case of this embodiment, the light emitting surface 40A is located in front of the wall surface C within the above-mentioned "substantially the same surface" range.

As described above, the lighting device 40 is formed with a vertical length that is 90% or more of the height of the bathroom space S. The lighting device 40 is formed shorter than the height of the bathroom space S in length including the lower cap 45 and the upper cap 46. This ensures a sliding allowance when the lighting device 40 is slidably engaged with the frame 51. After the lighting device 40 is fixed to the frame 51, the spacer 47 is fitted into the upper part of the lighting device 40. Thereby, the lighting device 40 is held in a non-slidable state with respect to the frame 51.

As described above, the surface of the wall panel 23 forming the wall surface B is formed in a different manner from the surfaces of the wall panels 22 and 24. The surface of the wall panel 23 is formed so that it becomes bright and dark when it receives illumination light from the lighting device 40. Specifically, the surface of the wall panel 23 is formed in an uneven shape. Therefore, as shown in FIG. 9, when the wall surface B of the bathroom space S formed by the wall panel 23 receives the illumination light from the lighting device 40, the brightness and darkness due to the unevenness is clearly expressed. Specifically, the illumination light is received on one side of the convex part (the side where the lighting device 40 is arranged), and the convex part receives the illumination light on the other side (the side opposite to the side where the lighting device 40 is arranged). Form the shadow of the shaped part. In this way, the wall surface B produces brightness and darkness due to the illumination light, contributing to the expansion of the bathroom space S and the improvement of its quality. In the case of this embodiment, the surface of the wall panel 23 is decorated with rough and irregular irregularities that imitate stones.

Next, the effects of the bathroom unit 1 will be explained. The bathroom unit 1 includes a wall panel 23 and a lighting device 40. The wall panel 23 forms a wall surface B of the bathroom space S. The lighting device 40 emits illumination light along the wall surface B from the side. The wall surface B is formed so that when it receives the illumination light from the illumination device 40, brightness and darkness occur.

When the bathroom unit 1 is irradiated with illumination light from the lighting device 40, brightness and darkness occur on the wall surface B. In this way, by creating brightness and darkness on the wall surface B, it is possible to make the user feel the spaciousness of the bathroom space S. Therefore, the bathroom unit 1 can improve functionality through irradiation with illumination light.

The bathroom unit 1 includes a floor member 10 and a ceiling panel 30. The floor member 10 forms a floor surface 10A of the bathroom space S, and wall panels 21, 22, 23, and 24 rise from the peripheral edge. The ceiling panel 30 is arranged above the wall panels 21, 22, 23, and 24 to form a ceiling surface 30A of the bathroom space S. The lighting device 40 has a light emitting surface 40A. The light emitting surface 40A extends vertically in a long shape from the floor surface 10A of the bathroom space S to the ceiling surface 30A.

In the bathroom unit 1, long light is emitted in the vertical direction from a light emitting surface 40A that extends vertically in an elongated manner between a floor surface 10A and a ceiling surface 30A. This allows the user to feel the spaciousness of the bathroom space S, which is a limited and narrow space. In particular, the height of the bathroom unit 1 is emphasized by emitting vertical light in the vertically long bathroom space S, making it possible to feel the spaciousness of the space.

The lighting device 40 emits long light in the vertical direction from the wall surface C of the bathroom space S, so that the user of the bathroom unit 1 who is standing on the floor surface 10A receives illumination light that illuminates the whole body from the side. It can irradiate efficiently. For example, in the case of ordinary lighting that is attached to the ceiling and emits illumination light downward, if the shower head of an overhead shower is placed below the lighting, a shadow of the shower head will be created. When irradiating light from the side (horizontal direction) as in this embodiment, it is possible to illuminate the user without creating a shadow from an overhead shower. In this manner, in the bathroom unit 1, by emitting vertically long illumination light from the side from the illumination device 40, it is possible to efficiently emit illumination light that illuminates the entire body of the user.

The surface of the wall panel 23 forming the wall surface B of the bathroom space S is formed into an irregular uneven shape. When illumination light is irradiated from the side along the wall surface B by the illumination device 40, irregular brightness and darkness due to unevenness is clearly generated on the wall surface B that receives the illumination light. In this way, the bathroom unit 1 has unevenness formed on the surface of the wall panel 23 forming the wall surface B, and the illumination light is irradiated from the side to the wall surface B, so that the wall surface B has bright and dark areas. Gradation can be effectively created.

In the bathroom unit 1, the surface of a wall panel 23 forming a wall surface B is decorated with a sheet imitating stone grain. Therefore, it is possible to create a sharp atmosphere in the bathroom space S due to the texture of the stone, and it is also possible to obtain a presentation effect due to the difference in texture between the wall surface B and the other wall surfaces E, A, and C.

The wall surface B irradiated with the illumination light appears brighter than the other wall surfaces E, A, and C. Therefore, it is possible to obtain a presentation effect based on the difference in brightness between the wall surface B and the other wall surfaces E, A, and C.

In the bathroom unit 1, a bathroom door 3 is provided on a wall surface E of a bathroom space S, and a lighting device 40 irradiates a wall surface B opposite to the wall surface E with light. In this way, the bathroom unit 1 irradiates the illumination light onto the wall surface B opposite to the wall surface E on which the bathroom door 3 is provided, so that the wall surface B that is directly irradiated with the illumination light is exposed to the other wall surfaces E, It is brightly illuminated compared to A and C. Thereby, the depth from the bathroom door 3 can be made to feel wider. In this way, the bathroom unit 1 can make the bathroom space S feel more expansive to the user who wants to enter the bathroom through the bathroom door 3.

The bathroom unit 1 is a shower unit having a vertically long and narrow bathroom space S. In the bathroom unit 1, a lighting device 40 having a vertically elongated light emitting surface 40A is arranged at a corner BC farthest from the bathroom door 3. Therefore, the user of the bathroom unit 1 can feel that the length and depth of the bathroom space S in the vertical direction are larger.

The bathroom unit 1 includes a shower device 2, and an operating section 2A of the shower device 2 is provided on a wall surface C. The lighting device 40 is provided at a corner BC of the wall C on the wall B side and irradiates the wall B with illumination light. With such a configuration, the bathroom unit 1 can brightly illuminate the wall B without casting the shadow of the operating section 2A of the shower device 2 on the wall B.

The length of the light emitting surface 40A of the lighting device 40 in the vertical direction is 90% or more of the distance from the floor surface 10A of the bathroom space S to the ceiling surface 30A. In this way, since the light emitting surface 40A of the lighting device 40 is formed with a length that spans almost the entire height of the bathroom space S, the length in the vertical direction is perceived as large by the user of the bathroom space S. It is possible to fully demonstrate the effect of

The bathroom unit 1 is constructed by fitting transparent glass as a light-transmitting member into substantially the entire inside of the door frame of the bathroom door 3. Thereby, the bathroom space S can be visually recognized from the space of the adjacent washroom W. When illumination light is emitted from the lighting device 40, the wall surface B located furthest from the washroom W is brightly illuminated. Thereby, the bathroom unit 1 can produce a so-called savanna effect. That is, the bathroom unit 1 can present the bathroom space S as a space with a sense of security.

In the bathroom unit 1, a wall surface B, which is a wall surface facing the bathroom door 3, is evenly illuminated from the lateral direction by the lighting device 40. In this way, the bathroom unit 1 can obtain a so-called wall washer effect by brightly illuminating the wall surface B facing the bathroom door 3 from the side. That is, the bathroom space S can be made to feel bright and spacious to the user of the bathroom unit 1.

The present disclosure is not limited to the disclosure of Embodiment 1 explained with the above description and drawings, but also includes, for example, the following embodiments.

(1) The configuration of the lighting device is not limited to that shown in Embodiment 1. For example, the configuration of the light source unit, the shape and presence of each member such as the casing and the transparent cover, the mounting form, etc. can be selected as appropriate.

(2) The lighting device may be provided with a length spanning substantially the entire length from the floor surface to the ceiling surface of the bathroom unit. For example, the lighting device may have a light emitting surface having a vertical length approximately equal to the length from the floor surface to the ceiling surface of the bathroom unit. This allows illumination light to be irradiated from the floor surface to the ceiling surface without interruption.

(3) The arrangement of the lighting device is not limited to the arrangement shown in the first embodiment. The lighting device may be placed on a wall surface different from that in Embodiment 1, such as on a wall surface opposite to the wall surface on which the bathroom door is provided.

(4) The arrangement, opening/closing manner, etc. of the bathroom door are not limited to those in the first embodiment. The bathroom door is not limited to the hinged door shown in Embodiment 1, but may be a folding door, a sliding door, or the like. In the case of a hinged door, it is not limited to opening inward, but may be opening outward.

(5) The shape of the bathroom space is not limited to the shape shown in the first embodiment. For example, the bathroom space may be approximately square in plan view, or at least a portion of the wall surface may be formed in a curved shape. The size of the bathroom space is also not limited to the size shown in the first embodiment. The height of the bathroom space can be, for example, about 2000 mm to 2200 mm. The size of the bathroom space in plan view can be, for example, 800 mm x 800 mm, 900 mm x 1400 mm, 800 mm x 1600 mm, or the like.

(6) The form of the wall surface is not limited to the form of the first embodiment. For example, as shown in FIG. 10, the surface of the wall panel 23 may be processed to have an uneven surface that resembles the scratches made by a chisel or a chisel, and decorated with a wood-grain sheet. In this case, in addition to the appearance of brightness and darkness when exposed to illumination light, a warm space can be created by the texture of the wood and the scratches left on the wood.

(7) The form of the wall surface is not limited to the form of the first embodiment. For example, as shown in FIG. 11, bright areas N and dark areas M may be formed regularly in response to illumination light.

(8) The wall surface may have a form that creates brightness and darkness by a combination of parts of different colors, such as a white part and a black part, or a part that reflects light and absorbs light, such as a mirror surface and a non-mirror surface. It may also be in a form that creates brightness and darkness depending on the combination with the parts. In this way, the wall surface may have a structure in which the reflectance or absorption rate of the illumination light is partially different, so that brightness and darkness occur when the wall surface receives the illumination light.

(9) The wall surface may be, for example, as shown in FIG. 12, in a form in which a transparent surface layer B2 is formed on a base layer B1 having an uneven surface, that is, a so-called inner emboss. In this case, while it is possible to generate brightness and darkness due to unevenness, the surface can be formed to be smooth, and both performance and cleanability can be achieved.

(10) The bathroom unit is not limited to the shower unit as shown in the first embodiment. For example, as shown in FIG. 13, the bathroom unit may include a bathtub BT. In this case, the lighting device may be provided to extend in the vertical direction from the upper end of the bathtub located at a height higher than the floor level to the ceiling surface, for example.

(11) The wall panel is not limited to the form rising from the peripheral edge of the floor member as shown in the first embodiment. For example, if the bathroom unit includes a bathtub (see FIG. 13), the wall panel may rise from the periphery of the bathtub.
