Detailed Description (054) The present invention relates to a modular bathroom pod assembled on-site at a custodial environment, and a modular bathroom pod kit to assemble on-site at the custodial environment. Figures 1 to 29 depict an embodiment of the modular bathroom pod (BP) according to the present invention. (055) The modular bathroom pod has a modular kit construction to allow the bathroom pod to be transported in modular kit form to a custodial establishment and assembled on-site in the custodial establishment. Due to the modular kit construction, the modular bathroom pod kit may be easily manoeuvred, and assembled, within the confined spaces of the custodial establishment. As such, the modular bathroom pod may be retrofitted in the custodial establishment. (056) When assembled on-site at the custodial establishment, the modular bathroom pod comprises an enclosure. The enclosure comprises a side wall, a floor, and an entrance. Depending on the configuration of the enclosure, the enclosure may comprise multiple side walls. (057) The bathroom pod further comprises one or more bathroom facilities arranged within the enclosure. For example, the bathroom pod may comprise at least one of a shower, a toilet, a wash-hand basin, a light or any other suitable bathroom facility mounted in the enclosure. (058) The enclosure may have any suitable shape. The shape may be based on the type of bathroom facilities, arrangement of the bathroom facilities, available space within the room of the custodial establishment, and / or the location of the bathroom pod within the room of the custodial establishment. The enclosure may have a regular or irregular shape. The enclosure may have a generally square, rectangular, ellipse or circular cross-sectional shape, and a respective cube, cuboid, ellipsoid or cylindrical three-dimensional shape. (059) If the enclosure has an ellipsoid or cylindrical shape, the enclosure may comprise a single side wall. If the enclosure comprises a multi-sided, multi-cornered shape (for example, a cube or cuboid shape), the enclosure may comprise multiple side walls. (060) The embodiment of the modular bathroom pod (BP) depicted in the Figures has a generally rectangular shape enclosure with four corners (C1, C2, C3, C4). As shown, the enclosure comprises a floor (F), four walls (W1, W2, W3, W4) defining four sides walls of the enclosure, and an entrance (E). The entrance is arranged between two walls (W1, W4). The modular bathroom pod is arranged in a corner of a custodial establishment room, where the corner of the custodial room is formed by custodial room walls (CEW1, CEW2). As can be seen in the Figures 1, 2 and 3, certain side walls (W1, W2) are outwardly facing side walls and so they are visible to a user external to the bathroom pod. Other certain side walls (W2, W3) are inwardly facing side walls that face the corner walls of the custodial room (CEW1, CEW2). In this embodiment, the modular bathroom pod comprises a toilet (T), a shower (S), a wash hand basin (B) and a light (L) mounted in the enclosure. (061) The floor of the enclosure comprises an impermeable floor tray module. By being impermeable, the floor tray module is fluid resistant. (062) The floor tray module comprises an impermeable tray base on which a user stands when using the bathroom pod. The tray base may comprise a slip resistant pattern to aid the grip of a user’s foot or shoe when standing on the tray base. (063) The floor tray module also comprises an impermeable tray perimeter wall. The tray perimeter wall is a peripheral wall of the floor tray module that extends circumferentially around the tray base. The tray perimeter wall is upstanding from the tray base, preferably substantially perpendicular to the tray base. (064) The tray base and tray perimeter wall are integral whereby the floor tray module has a single unit structure. The tray base and tray perimeter wall may be integrally attached (connected, conjoined) such that the floor tray module has an integrated, single unit structure. Alternatively, the tray base and tray perimeter may be integrally formed from one-piece such that the floor tray module has a monolithic, single unit structure. (065) Due to the single unit structure, the floor tray module is a modular component. The single unit structure of the floor tray module allows for easy transportation, manual handling and assembly of the bathroom pod. (066) As explained further below, when the modular bathroom pod is assembled onsite at the custodial establishment, the impermeable tray perimeter wall is configured to be a fluid containment barrier to aid the retaining of fluid within the bathroom pod and help minimise the unintended escape of fluid. (067) The impermeable tray perimeter wall comprises a wall portion and an entrance portion. When assembled on-site, the wall portion of the tray perimeter wall is arranged in association with the side wall, and the entrance portion of the tray perimeter wall is arranged in association with the entrance. If the enclosure comprises multiple side walls each comprising a wall module, the tray perimeter wall comprises multiple wall portions, and each wall portion is arranged in association with a respective side wall. The, or each, wall portion of the tray perimeter wall forms a wall fluid containment barrier with respect to the associated side wall of the bathroom pod. The entrance portion of the tray perimeter wall forms an entrance fluid containment barrier at the entrance of the bathroom pod. (068) The fluid containment effect of the impermeable tray perimeter wall depends on the height of the tray perimeter wall. The tray perimeter wall may have a height falling within the range of approximately 5cm to 10cm. The height of the tray perimeter wall may be substantially the same along its length. Alternatively, the height of the tray perimeter wall may vary. For example, the height of the at least one wall portion and the entrance portion may be substantially the same or different. (069) The floor tray module may have any suitable shape and configuration according to the desired shape of the bathroom pod enclosure. For example, the floor tray module may have a regular or non-regular shape. The floor tray module may have a square, rectangular, ellipse or circular cross-sectional shape. The tray base may be substantially planar or the tray base may be inclined towards a waste. (070) The floor tray module may comprise stainless steel, mild steel, resin or plastic. The floor tray module may comprise a panel with an impermeable surface layer or coating, or any other suitable impermeable material. For example, the floor tray module may comprise a compact grade laminate with a resin surface layer. (071) As shown in the Figures, the embodiment of the modular bathroom pod (BP) comprises a floor tray module (1) with a rectangular shape. As seen in Figures 4 and 5, the floor tray module comprises a tray base (1a) and an upstanding tray perimeter wall (1b). In this embodiment, the tray perimeter wall comprises four wall portions - a first wall portion (1b1), a second wall portion (1 b2), a third wall portion (1b3) and a fourth wall portion (1b4). The tray perimeter wall also comprises an entrance portion (1b5). When the bathroom pod is assembled on-site at the custodial establishment, each wall portion of the tray perimeter wall (1 b1-1 b4) is arranged in association with a respective side wall (W1-W4) of the enclosure, and the entrance portion of the tray perimeter wall (1b5) is arranged in association with the entrance (E) of the enclosure. In this embodiment, the tray base is substantially planar. The floor tray module is a one-piece, single unit where the tray base and tray perimeter wall are integrally formed from a single piece of 3mm thick stainless steel plate. The wall portions (1 b1-1 b4) have a height of approximately 10cm and the entrance portion (1b5) has a height of approximately 6cm. (072) The floor of the enclosure may comprise a waste through which waste fluid may drain from the bathroom pod via the floor tray module. (073) As shown in the Figures, the embodiment of the modular bathroom pod (BP) comprises a waste (2). As seen in Figure 6, the waste (2) has a waste aperture (2a), waste cover (2b) and waste trap (2c). The waste aperture (2a) is formed in the tray base (1a), and the waste cover (2b) extends over the waste aperture to guide waste fluid to the waste trap (2c). (074) The floor may further comprise a floor frame module to support the floor tray. The floor frame module is a modular component with a single unit frame structure. As such, the floor frame module may be easy to transport and handle when assembling the bathroom pod on-site. The floor frame may comprise a plurality of floor frame members integrally attached to form the single unit frame structure. (075) The floor frame module may be formed from stainless steel or mild steel. (076) The enclosure may comprise fixings to secure the floor frame module to the floor tray module during assembly of the bathroom pod on-site at the custodial establishment. The fixings may comprise mechanical fixings and / or any other suitable fixings. (077) The enclosure may comprise fixings to secure the floor frame module to the floor and / or a wall of the custodial establishment during the assembly of the bathroom pod on-site at the custodial establishment. The fixings may comprise mechanical fixings and / or any other suitable fixings. (078) As shown in the Figures, the embodiment of the modular bathroom pod comprises a rectangular shaped floor frame module (3) to support the rectangular floor tray module (1) in-situ within the custodial establishment. In this embodiment, the floor frame module is secured to the floor of the custodial establishment (CEF) using mechanical fixings (not shown), and the floor tray module is secured to the floor frame module using mechanical fixings (not shown). As seen in Figures 7 and 8, the floor frame module is configured to form a void space (V) between the floor of the custodial establishment and the floor tray module to permit the arrangement of the waste trap (2c), drain pipes, fluid pipes, electrical wiring, insulation etc under the floor tray module. (079) The, or each, side wall of the enclosure comprises a wall module. (080) The wall module comprises a wall frame and an impermeable wall inner cladding. By being impermeable, the wall inner cladding is fluid resistant. (081) The wall frame and wall inner cladding are integral such that the wall module is a single unit. The wall frame and wall inner cladding may be integrally attached (connected, conjoined) such that the wall module has an integrated, single unit structure. Or the wall frame and wall inner cladding may be integrally formed from one-piece such that the wall module has a monolithic, single unit structure. (082) Due to the single unit structure, the wall module is a modular component. As a result, wall module can be easily transported and manually handled during the assembly of the bathroom pod on-site at the custodial establishment. (083) The wall frame of the wall module may comprise wall frame members configured to provide the wall module with rigidity. The wall frame members may be configured to form a lattice or grid structure. For example, the wall frame may comprise opposing side frame members, a top frame member and / or a bottom frame member, configured to extend along an edge of the wall module. (084) The wall frame of the wall module may be formed from stainless steel or mild steel. (085) The wall inner cladding may comprise stainless steel, mild steel, resin, plastic, a panel with an impermeable surface layer or coating, or any other suitable impermeable material. The wall inner cladding may comprise a stainless steel sheet or mild steel sheet. The wall inner cladding may comprise a resin sheet or a plastic sheet. The wall inner cladding may comprise a compact grade laminate panel with a resin surface layer. (086) When the wall frame and wall inner cladding are integrally attached to form the single wall module unit, the wall inner cladding may be secured to the wall frame using fixings, and / or the wall inner cladding may be welded to the wall frame. (087) The wall module may be any suitable shape and configuration according to the desired shape of the bathroom pod enclosure. For example, the wall module may have a regular or non-regular shape. The wall module may have a square or rectangular shape. The wall module may be substantially planar or have a curved profile. (088) In the embodiment of the modular bathroom pod (BP) shown in the Figures, each side wall comprises a wall module (4) with an integral wall frame (4a) and a wall inner cladding (4b). As seen in Figures 9, 10 and 11, a first wall module of the first side wall (41) comprises an integral first wall frame (4a1) and afirst wall inner cladding (4b1), a second wall module of the second side wall (42) comprises an integral second wall frame (4a2) and a second wall inner cladding (4b2), a third wall module of the third side wall (43) comprises an integral third wall frame (4a3) and a third wall inner cladding (4b3), and a fourth wall module of the fourth side wall (44) comprises an integral fourth wall frame (4a4) and a fourth wall inner cladding (4b4). Each wall module has a rectangular shaped, flat panel structure. In this embodiment, each wall frame comprises side frame members extending along opposing sides of the wall module. The frame members are formed from stainless steel. The wall inner cladding comprises stainless steel sheet welded to the wall frame members. (089) When assembled on-site, the wall module is mounted on the tray base whereby the wall module is arranged on an inner side of the tray perimeter wall adjacent the wall portion of the tray perimeter wall, and the wall portion of the tray perimeter wall is thereby arranged on the outer side of the wall module. As such, the wall inner cladding forms a wall inner face of the enclosure that acts as a primary wall fluid containment barrier, and the tray perimeter wall acts as a secondary wall fluid containment barrier that provides a bunding effect with respect to the wall module. The primary wall fluid barrier and second wall fluid containment barrier provide a doublewall fluid barrier to aid the containment of fluid in the enclosure and impede the unintended escape of fluid. (090) If the enclosure comprises a plurality of side walls each having a wall module, each wall module is mounted on the tray base on the inner side of the tray perimeter wall and arranged adjacent a different wall portion of the tray perimeter wall. Each different wall portion of the tray perimeter wall is thereby arranged on the outer side of the respective wall module. As a result, the wall inner cladding of each wall module forms a different wall inner face and acts as a primary wall fluid containment barrier of the respective wall. Each wall portion of the tray perimeter wall acts as a secondary wall fluid containment barrier with respect to the respective wall. (091) When the, or each, wall module is mounted on the tray base, a sealed joint forms between the wall module and the floor tray to help maintain watertightness (fluid seal) of the enclosure. The enclosure may comprise fixings to securely engage the wall module to the floor tray. The fixings may comprise mechanical fixings and / or any other suitable fixings. For example, the enclosure may comprise mechanical fixings to securely engage the wall module to the tray perimeter wall. (092) When the enclosure of the bathroom pod comprises multiple side walls, a sealed joint forms between adjacent wall modules to help maintain watertightness (fluid seal) of the enclosure. The enclosure may comprise fixings to securely engage the wall modules of adjacent side walls. The fixings may be mechanical fixings, and / or any other suitable type of fixings. The mechanical fixings may comprise screws and bolts, clips, brackets, and / or any other suitable mechanical fixings. (093) In the embodiment of the modular bathroom pod (BP) shown in the Figures, each wall module of the side walls (41, 42, 43, 44) is mounted on the tray base (1a) and arranged on an inner side of the tray perimeter wall adjacent a different wall portion of the tray perimeter wall (1 b1, 1 b2, 1 b3, 1 b4). As seen in Figures 12 to 18, the first wall module (41) and first wall portion (1b1) are adjacent, and the first wall portion is arranged on the outer side of the first wall module. The second wall module (42) and second wall portion (1b2) are adjacent, and the second wall portion is arranged on the outer side of the second wall module. The third wall module (43) and third wall portion (1b3) are adjacent, and the third wall portion is arranged on the outer side of the third wall module. The fourth wall module (44) and fourth wall portion (1b4) are adjacent, and the fourth wall portion is arranged on the outer side of the fourth wall module. Mechanical fixings including screws and bolts (5) securely engage each wall module to the respective wall portion, and sealed joints form between the respective wall modules (41, 42, 43, 44) and the tray base (1a). As shown in Figures 16, 17 and 18, mechanical fixings including screws and bolts (5) and optional corner bracket plates (6) securely engage the wall frames (4a1, 4a2, 4a3, 4a4) of the adjacent wall modules together, and sealed joints form between the adjacent wall modules. Due to the configuration of each wall module, the impermeable wall inner cladding of each wall module (4b1, 4b2, 4b3, 4b4) forms a wall inner face of the enclosure that acts as a wall fluid barrier to provide primary fluid containment within the enclosure. Due to the configuration of the impermeable tray perimeter wall with respect to the wall modules, each wall portion of the tray perimeter wall (1 b1, 1 b2, 1 b3, 1b4) acts as a further wall fluid barrier to provide secondary fluid containment within the enclosure. As a result, the wall portions of the tray perimeter wall provide a bunding effect to help contain fluid within the enclosure and reduce the risk of flooding in the custodial establishment if a wall module fails and / or joint fails.
