The present invention relates generally to showers, bathroom floors and other drainable structures that are part of a prefabricated bathroom pod construction or other similar types of modular building units, and more particularly to pod bathroom floors where the pod bathroom floor is reinforced and integrated into the bathroom pod or other building unit in such a manner as to add significant strength to the bathroom pod to resist bending, twisting and sagging, and/or to aid in lifting and supporting the weight of the bathroom pod floors and walls.
Most bathroom shower enclosures are created using complicated construction methods. For example, using conventional techniques, a skilled installer frames out the area to be enclosed using two-by-four wooden, steel or aluminum studs to create a shower enclosure space. Felt or tar paper is then laid over a subfloor area enclosed within the space. A flexible, leak-proof liner is installed on top of the felt or tar paper and attached to the frame. Next, the installer attaches dry wall boards to the framing studs, creating shower sidewalls. A hole is cut in the liner to allow for a drain, and a layer of mortar is applied to the shower sidewalls and curb and allowed to cure. Additional mortar is applied on top of the leak-proof liner and hand-shaped to form a shower floor which slopes toward the drain such that water from the shower flows toward the drain. After the mortar has cured, shower tile is applied to the floor and sidewalls to create the finished enclosure.
The process of creating an enclosed shower in this manner is time-consuming and requires experience, knowledge and skill in order to maintain the proper pitch and uniformity in shaping the floor. Irregularities in the pitch of the floor can cause water from the shower not to drain properly or make tiling the shower enclosure difficult. The liners are also susceptible to punctures or leaks and may be difficult for the installer to properly form square corners at the intersection of the shower sidewalls and floor. Additionally, the mortar layer used to create the floor is necessarily thick in order to form a sloped surface, therefore the time required for the floor to cure before applying tile may be quite long (e.g., greater than 24 hours). As a result, construction projects that require a multitude of showers or bathrooms to be fabricated such as residential complexes, hotels, and hospitals will be more expensive and take longer due to the required labor.
In recent years, to decrease this cost especially for the aforementioned commercial applications, the process of shower installation has been vastly improved by the introduction of prefabricated shower bases used for forming the shower floor. Use of these prefabricated shower bases significantly decreases the amount of time and skill required to construct a bathroom shower enclosure, as well as providing more of a consistent and reliable flooring surface upon which to apply floor coverings. These shower bases are pre-constructed molded units having a sloping floor, an integrated drain, curb, sidewalls, and a horizontal surface on the top of each sidewall for receiving drywall such that the drywall surface is substantially flush to the shower base sidewalls. Installation of the shower base involves securing a section of drain pipe to the drain, applying adhesive and sealing material to the sub floor where the base will rest, and seating the base on the subfloor. Tile can then be applied directly to the shower walls and shower base without the need for first applying mortar.
Other improvements in the construction process have included the provision of entire prefabricated bathroom pods, that are assembled off-site and installed in a building under construction to decrease the cost of labor when building suites in the aforementioned commercial applications.
However, more than just prefabricated shower components are needed to create prefabricated bathroom pods. In particular, there exists a need to make the entire bathroom floor a monolithic and fortified component of such pods that are sturdy enough to withstand the weight and forces exerted on the bathroom floor and other pod components during fabrication, lifting, transport and installation, without fear of damage occurring to the bathroom floor or another part of the prefabricated bathroom pod.
Bathroom pod construction is a new and growing competitive construction segment which has certain advantages over conventional construction methods, particularly in large new built projects. Bathroom pod manufacturers have been successful in eliminating many deficiencies associated with traditional bathroom construction methods undertaken in the field on a construction site by having pod company employees responsible for all or substantially all of the construction and assembly of a pod in a factory setting. When the bathroom pod is finished, it is shipped to a construction site where it is lifted and then installed in the structure as a finished bathroom.
The factory environment allows significantly more oversight and control over how and when a pod is manufactured, including sequencing different groups of pod employees based upon when their trade expertise is required. Pod supervisors are also readily available to oversee real time work quality, sequencing and scheduling.
With all employees working for the pod manufacturer, the pod employees avoid many of the friction occurring on a traditional construction site between and among different trades present in traditional construction, including, among other things, one trade intentionally or recklessly negatively impacting finished work of another trade.
Bathroom pod manufacturers have introduced meaningful innovation in the construction of bathrooms. However, that innovation has not, for the most part, trickled down to the construction of pod bathroom floor components. Currently, portions of the pod bathroom floor are still being manufactured in much the same way that bathroom floors have been manufactured for years in conventional construction. Bathroom pods are still installed with basic substrates on which pod floors are assembled and installed using a series of off-the-shelf bathroom products which basically mimics traditional (i.e., non-modular) construction practices. Consequently, pod bathroom floors share many of the same headaches and drawbacks associated with traditional construction, along with several additional meaningful drawbacks that are uniquely attributable to pod construction. For example, since pods are manufactured in a factory, they must be shipped from the factory to the construction site and then placed on substrates in buildings with any number of stories. Heretofore, the interconnections between bathroom pod floors and the walls of the pod have not employed independent weight bearing substrates or anti-torsional features which prevent pod floors and/or walls from twisting, bending, sagging and/or otherwise potentially compromising the installed floor and wall coverings, causing them to loosen or dislodge from the pod floor and/or walls when the completed pod is installed on a traditional construction site substrate.
With the introduction of the herein disclosed new reinforced pod bathroom floor systems, the bathroom pod industry will now have a one-piece pod flooring system which will revolutionize how the bathroom pod industry manufactures bathroom pod floors. Most importantly, the one-piece pod bathroom floor systems provide a full menu of custom solutions for the bathroom pod industry which are not otherwise available and will save significant time and cost. The inventions set forth in this application address many of the thorny issues currently plaguing the bathroom pod manufacturers related to the bathroom pod component. Specifically, the pod bathroom floor component described herein not only provides one or more bathroom shower floors, it also provides all the other bathroom floor structures which include but are not limited to one or more flat bathroom areas, one or more non-shower pitched bathroom wet areas, one or more dry pitched bathroom areas, the entrance to the bathroom, along with any custom size bathroom floor component required, while also having the pod bathroom floor entrance component fit into a shallow substrate slab recess (for example, 1.5″), thereby avoiding the excessive costs of recessing the slab even more. Most importantly, all of the above is contained in a one-piece bathroom floor component, which has adequate independent weight bearing floor capabilities as well as being resistant to sagging, bending, twisting and other deformations, and in some embodiments also has pod wall weight bearing capabilities, so the bathroom pod manufacturer can order and receive a one piece pod bathroom floor component which can be assembled with the pod wall panels in a very short period of time (e.g., less than 45 minutes).

Representative Prefabricated Bathroom Pod with a Raised Peripheral Strengthening Wall-Support Platform
Given the size of the typical bathroom pod floor component and the weight of the bathroom pod once assembled, a robust method for resisting sagging, twisting, bending and other destructive forces during lifting, transport and installation of the bathroom pods is desired, as well as the needed structure to strengthen the floor component and support the weight of the bathroom walls and wall coverings, bathroom floors and floor coverings, accessories and ceiling panel.
A bathroom pod 100 according to an embodiment of the present disclosure will now be discussed with reference to
As seen in
Further, in some embodiments, a weight bearing raised platform 376 for supporting the pod walls is formed from the same one or more foam floor panels 304 referenced above to create a raised peripheral planar wall support surface 377 defining an outer raised platform perimeter of bathroom floor component 300. Additionally, one or more of the foam floor panels 304 may define a drain aperture 378, and define sloped upper surfaces 380 that are directed toward the drain aperture 378.
Typically, as seen in
Put another way, the walls may connect the ceiling to the bathroom floor component 300. The walls may include bottom frame members 112 which are adapted to align and be coplanar with upper surface 377. A plurality of hollow fastener-receiving journals or bushings 116 may be disposed in the plurality of apertures 114 defined by raised platform 376.

In doing so, the raised platform 376 is protected from crushing. The hollow interiors of bushings 116 allow fasteners 120 to extend through apertures 114 in raised platform 376 through the bottom wall of frame members 112 (see

Similarly,
The ceiling 102 may be monolithic, crack-proof, and water proof. The electrical wiring 106 and the plumbing 108 may be pretested and code compliant. The walls 104 may have moisture, mold and abuse resistant wallboard 107. Engineered steel framing studs 110 may hold the walls, and the pod floor component 100 as a whole, together. Accessories such as, but not limited to, a sink 115, rail 118, mirror 111 and foot rest 113 may also be provided.

In broader terms than heretofore discussed, a method for fabricating and/or using embodiments of the present disclosure may be characterized as follows with reference to
With reference to
The method 400 may further comprise milling or otherwise rendering a drain aperture in at least one or more of the floor members, and milling the top surface of one or more of the floor members, or portions thereof, with a pitch, such as but not by way of limitation, toward the drain aperture at any appropriate time(s) (step 414).
In some embodiments, the method 400 may further comprise applying a waterproof sealant to the one or more of the plurality of floor members and the longitudinal strengthening member(s) 302 (step 416).
Looking now at
The method 500 may comprise machining a first plastic and/or foam floor member with at least one sloped surface extending downwardly toward a drain aperture and a peripheral strengthening raised platform member (step 502), machining a second foam floor member with a peripheral strengthening raised platform member (step 503), providing one or more longitudinal strengthening member(s) (step 504), joining the first and second floor members to opposite side edges of the longitudinal strengthening member (step 506), and applying a waterproof sealant to the assembly (step 514).
Step 506 may include attaching the floor members to the longitudinal strengthening member by fastening or bonding using an adhesive (step 510).
The method may further comprise creating a contour in the upper surface of the longitudinal strengthening member(s) 302 to coincide with the contour of the upper surface of the adjacent floor members to render the upper surfaces of the longitudinal strengthening member(s) 302 coplanar with the contour of the upper surface of the adjacent floor members, to permit application of a floor covering (e.g., floor tile) that is to be attached to the floor members and the longitudinal strengthening member(s), if any (step 516).
Optionally, a raised peripheral support platform member, such as raised peripheral platform 376 shown in
As alluded to earlier herein, once the floor component has been manufactured with a wall strengthening raised peripheral platform, then it may be attached to the walls, and indirectly the ceiling, etc., to make an assembled bathroom pod.
With reference to
At step 414, a drain aperture is milled or otherwise rendered in the floor panel, as well as any desired floor pitch/slope.
In step 406, the raised platform 1076 of the bathroom floor component is placed in registry with the floor frame 1050
The bathroom floor panel 1004 and frame 1050 are then coated with a waterproof coating 325 as described above, which not only creates a waterproof floor component but adds significant strength and rigidity to the bathroom floor component and, thereby, to the pod overall.
The raised support platform 1076 coincides substantially with a footprint defined by lower edges of the pod walls 104. The lower edges of the pod walls 104 are placed in registry with the raised platform 1076 and fastened to the pod walls 104. Wall and floor covering material such as wall and floor tile 390, 394 may thereafter be applied to the pod walls and floor in a manner well known to those skilled in the art. A sturdy pod is thus created, and can be transported to and installed at a construction site.
At step 414, a drain aperture is milled or otherwise rendered in one of the floor panels, as well as any desired floor pitch/slope.
In step 406, the raised platforms 1076L and 1076R of the bathroom floor panels 1004L, 1004R are placed in registry with the floor frame 1050.
The bathroom floor panels 10041, 1004R and frame 1050 are then coated with a waterproof coating 325 as described above, which not only creates a waterproof floor component but adds significant strength and rigidity to the bathroom floor component and, thereby, to the pod overall.
The raised support platforms 1076L, 1076R coincide substantially with a footprint defined by lower edges of the pod walls 104. The lower edges of the pod walls 104 are placed in registry with the raised platforms 1076L, 1076R and fastened to the pod walls 104. Wall and floor covering material such as wall and floor tile 390, 394 may thereafter be applied to the pod walls and floor in a manner well known to those skilled in the art.
Representative Prefabricated Bathroom Floor Component Without Weight Bearing Perimeter Raised Platform.
The bathroom pod 100 as shown may comprise a ceiling 102, a plurality of walls 104, electrical wiring 106, plumbing 108, and a bathroom floor component. As shown in
In this embodiment, a support panel or substrate 785 supports and is the substrate for bathroom floor component 700, and the outer periphery of bathroom floor component 700 fits substantially within the area defined by inner-facing surfaces of wall board material 107.
Support substrate 785 in turn is attached to bathroom pod 100 in any desirable manner. One such manner is to connect the substrate to the walls 104 of the pod 100. In embodiments, substrate 785 may be connected to walls 104 by mechanical connection therebetween, an example of which can be seen in the drawings. Fasteners 120, such as nut and bolt arrangements, may connect the substrate 785 to the pod wall bottom frame members 112. In this way, the bathroom floor component 700 is supported by substrate 785 and walls 104 when the pod 100 is not supported itself on a floor such as a factory floor, transport vehicle or final building floor slab. Support substrate 785 may be manufactured of PVC, wood, metal, or any other material capable of supporting the weight of the floor member 700.
Any suitable fastener 120 may be used including nuts and bolts, dry wall screws and the like. Bottom wall frame members 112 are preferably aligned with upper peripheral surfaces of substrate 785. The fasteners 120 may engage one or more of the bottom frame members 112 through apertures 714 defined by the substrate 785.
Typically, as seen in
Similarly,
The ceiling 102 may be monolithic, crack-proof, and water proof. The electrical wiring 106 and the plumbing 108 may be pretested and code compliant. The walls 104 may have moisture, mold and abuse resistant wallboard 107. Engineered steel framing studs 110 may hold the walls, and the bathroom floor component and the pod 100 as a whole, together. Accessories such as, but not limited to, a sink 115, rail 118, mirror 111 and foot rest 113 may also be provided. One or more of these features or attributes may be omitted in other embodiments of the present disclosure.

Bathroom Floor Components Including Underside Strengthening Members
The raised platform 976 is adapted to bear the weight of at least a portion of the walls 104 and ceiling 102 of pod 100, including the weight of any accessories attached thereto, and as such will be constructed and arranged in such a manner that it can support said weight without distortion (e.g., will resist collapse, crushing or bending). To that end, the material out of which peripheral shoulder 976 is manufactured will be sufficient to support the weight of the ceiling 102 and walls 104. Alternatively, strengthening inserts 979 and 989 may be integrated into the peripheral raised platform 976 to add weight-bearing and anti-compressive capacity to the raised platform component 976 of the bathroom floor component 900.
Additionally, the walls 104 of the bathroom pod 100 may connect the ceiling to the bathroom floor component 900. The walls 104 may include bottom frame members 112 which are adapted to be placed in registry with upper surface 977. A plurality of hollow fastener-receiving bushings or journals 116 may be disposed in the plurality of apertures 114 defined by raised platform 976. These bushings 116 may act as alignment features when the walls are fastened to the bathroom floor component 900, act to protect the integrity of apertures 114, which in some embodiments are formed in the polystyrene or other relatively soft foam making up support platform 976, and act to transfer weight from the walls 104 to the sub-floor (not shown) supporting pod 100. In doing so, the raised platform 976 is protected from crushing. The hollow interiors of bushings 116 allow fasteners 120 to extend through apertures 114 in raised platform 976 through the bottom wall of frame members 112.
Bushings 116 similar to those depicted in other embodiments herein, such as metal cylindrical journals (not shown), which are preferably fabricated of metal, although any material having good compression resistance is suitable, may be used transfer weight from the walls 104 down to the supporting surface or substrate (not shown) on which the bathroom floor component 900 will sit.
Alternatively or additionally, weight bearing supporting inserts such as intermediate inserts 979 and corner inserts 989 may be used to support the weight of walls 104 and ceiling 102. Fasteners may be used to attach the walls 104 to the bathroom floor component 900 as described elsewhere in this disclosure, using corresponding apertures 114 defined by support inserts 979 and 989.
Support straps or bars 990 may be employed to transfer compressive forces from walls 104 to tensile forces exerted within bars 990. Bars 990 also serve to strengthen bathroom floor component 900, and ultimately pod 100, against twisting, bending a sagging action. Preferably, bars 990 are recessed in corresponding slots 991 formed in the lower surfaces of floor panels 904 and transverse strengthening members 902 so as not to add any height dimension to the profile of the bathroom floor component 900. Bars 990 may be associated with bathroom floor component 900 either before or after floor component 900 is encapsulated with waterproofing sealant 325.
In embodiments, bars 990 connect to walls 104 in the same manner as described in connection with the interconnection of walls 104 with raised support platform 976.

In embodiments, such as shown in
Moreover, in any of the disclosed embodiments, one or more of the additional or alternative features such as the following may be included in the bathroom floor component:
Strengthening members such as those described throughout this disclosure, including the anti-compressive members, provide support and rigidity for the bathroom floor components. Certain strengthening members are focused exclusively on strengthening the bathroom floor feature of a bathroom floor component. Other strengthening members are focused exclusively on strengthening the raised platform feature of the bathroom floor component. A third category of strengthening members are focused on strengthening both the bathroom floor feature and the raised platform feature of the bathroom floor component.
Strengthening members can comprise any type of material, including but not limited to wood, metal, plastic, concrete, stone, polyurethane, along with any and all other types of structures or apparatus that would be adequate for peripheral or transverse strengthening purposes. These materials may be used individually and in combination with other materials depending upon the specific support requirements of a specific bathroom floor feature and a specific raised platform feature of a specific bathroom floor component.
For the bathroom floor component strengthening members, their support characteristics are specific to where they are located in the bathroom floor component.
For all embodiments, the heads of fasteners 120 are preferably recessed into the respective apertures 114, particular at the bottom of raised platforms 376, 776 and 976, so as not to unnecessarily add to the height of the bathroom floor component. Appropriate weight-dispersing features such as washers and/or bushings 116 may be employed to distribute forces to the extent necessary to avoid cracking or other disturbance in the waterproof layer 325 or any other aspect of the bathroom floor component.
The top surfaces 377, 1077 of the raised support platforms in all embodiments are preferably horizontal. Fasteners and fastener-receiving structures are preferably recessed in the raised platform to maintain a uniformly flat and thin profile.
It is understood that the raised platform is not needed where there is a threshold into the bathroom, such as in the doorways shown in
Frame member 1050 acts as a strengthening member for both the floor and the raised platform, along with providing strengthening to any other member with which it is associated. In this, resistance to bending, twisting and sagging is provided.
It is also to be understood that bathroom pods manufactured in accordance with the description set forth herein are typically set upon substrates, in many cases concrete slabs, in buildings under construction. It is desired to avoid changes in height when going from the substrate/floor of the building into the prefabricated bathroom pod (for example, at an entrance area 180 of any of the floor members described herein) to avoid tripping and/or to meet various disability codes. In some cases, recesses are provided in such building floor substrates to accommodate the depth necessary for sloped shower floors. The bathroom floors of the present invention, containing one or more drains, in most cases employ floors which slope toward such drain(s). The slope of the floors requires the bottom surfaces of the bathroom floor components disclosed herein to have a certain clearance depth accommodated by the substrate, which in appropriate cases is accomplished by creating a recess in the upper surface of the substrate. Preferably, selecting combined dimensions of the thickness of the floor member of the bathroom floor components, and the depth of any recess(es) in the building floor substrate which the bathroom floor member sits in, results in the upper surface of the finished floor of the bathroom floor component immediately adjacent the bathroom pod entrance being at substantially the same height as the finished floor of the building into which the bathroom pod is being installed immediately adjacent the bathroom pod entrance. Alternatively, the height of the unfinished floor at the bathroom pod entrance may be engineered to be at substantially the same height as the adjacent room.
It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the apparatus and methods of assembly as discussed herein without departing from the scope or spirit of the invention(s). Other embodiments of this disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the various embodiments disclosed herein. For example, some of the equipment may be constructed and function differently than what has been described herein and certain steps of any method may be omitted, performed in an order that is different than what has been specifically mentioned or in some cases performed simultaneously or in sub-steps. Furthermore, variations or modifications to certain aspects or features of various embodiments may be made to create further embodiments and features and aspects of various embodiments may be added to or substituted for other features or aspects of other embodiments in order to provide still further embodiments.
Accordingly, it is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention(s) being indicated by the following claims and their equivalents.
