- the shower stall includes a shower base, a drywall board enclosure, and a finished wall surround.
- the shower base includes a generally horizontal floor, a threshold for entry and exit into the shower stall, and a side wall.
- the horizontal floor portion of the shower base is supported by a subfloor and includes the shower drain.
- the threshold of the shower base may be a rounded or contoured portion that may be of the same or reduced height compared to the side wall.
- the threshold defines entry and exit regions for shower stall.
- the drywall board enclosure and the finished wall surround extend around the periphery of the shower base, except for the threshold.
- a shower stall door or shower curtain normally overlies the threshold to allow ingress and egress form an interior region of the shower stall defined by the shower base and the finished wall surround.
- the drywall board enclosure includes a plurality of drywall boards in side-by-side arrangement.
- the drywall boards may comprise drywall cement board, greenboard, sheetrock gypsum, or other drywall material of suitable construction to form a drywall board enclosure in shower installations.
- all such drywall boards/materials that comprise the drywall board enclosure shall generally be referred to as “drywall board”.
- the drywall board is affixed to vertical framing studs supporting the shower stall.
- the finished wall surround is typically affixed to the drywall board and/or vertical framing studs supporting the shower stall.
- the finished wall surround defines an interior region of the shower stall and may comprise plastic or fiberglass panels or may comprise a plurality of tiles affixed to the drywall board.
- finished wall all such finished wall surround panels/materials that comprise the finished wall surround shall generally be referred to as “finished wall”.
- the side wall of the shower base includes a generally vertical lower portion and a generally L-shaped tile flange extending outwardly and upwardly from the vertical lower portion of the side wall.
- the L-shaped tile flange includes a horizontal base and a vertical upright extending vertically upwardly from the horizontal base. Positioned above the vertical upright of the L-shaped tile flange is a bottom wall or edge of the drywall board. The finished wall of the shower stall is installed over the drywall board and extends down and contacts the horizontal base of the tile flange.
- caulking such as a silicone sealant caulk
- caulking is applied as a bead of caulking to fill in an area between a back side of the finished wall, the vertical upright of the tile flange and the bottom wall of the drywall board, including the gap between the bottom wall of the drywall board and the upper edge of the vertical upright of the tile flange, to prevent water from entering the bottom wall of the drywall board and being wicked upwardly through the drywall board and/or leaking or migrating into the gap between the upper edge of the vertical upright and the bottom wall of the drywall board which would result in moisture or wetness along the back side of the drywall board and/or on vertical or horizontal framing studs supporting the shower stall.
- Moisture or wetness gathering on the back side of the drywall board and/or on the framing studs is problematic for a number of reasons including deterioration or rotting of the drywall board and/or the framing studs over time and the potential for mold/mildew growth, because, depending on the location of the shower stall within the building, there may be limited air circulation in the region of the framing studs.
- caulking While application of caulking between the bottom wall of the drywall board and the vertical upright of the tile flange attempts to address the water leakage water problems noted above, caulking is not a reliable, long-term solution.
- the application of caulking is typically done by an installer using a manual or powered caulking gun.
- the ability to apply a proper, uniform-sized bead around the entire periphery of the tile flange is problematic and is dependent on the skill of the installer. In some regions, the installer may apply a caulking bead that is too thick, wasting caulking and potentially causing excess caulking to ooze down the side wall of shower base.
- the installer may apply a caulking bead that is too thin to provide an adequate seal to inhibit water migration into the gap between the bottom edge of the drywall board and the tile flange. Additionally, over time, caulking tends to lose flexibility, stiffen and deteriorate, compromising the water seal provided by the caulking bead.

The finished wall of the shower stall is installed over the drywall board and extends down and contacts the horizontal base of the tile flange.
- Typically, there is a small vertical gap between a bottom wall or edge of the drywall board and an upper edge of the vertical upright of the tile flange. In typical prior shower stall installations, caulking, such as a silicone sealant caulk, is applied as a bead of caulking to fill in an area between a back side of the finished wall, the vertical upright of the tile flange and the bottom wall of the drywall board, including the gap between the bottom wall of the drywall board and the upper edge of the vertical upright of the tile flange, to prevent water from entering the bottom wall of the drywall board and being wicked upwardly through the drywall board and/or leaking or migrating into the gap between the upper edge of the vertical upright and the bottom wall of the drywall board which would result in moisture or wetness along the back side of the drywall board and/or on vertical or horizontal framing studs supporting the shower stall. Moisture or wetness gathering on the back side of the drywall board and/or on the framing studs is problematic for a number of reasons including deterioration or rotting of the drywall board and/or the framing studs over time and the potential for mold/mildew growth, because, depending on the location of the shower stall within the building, there may be limited air circulation in the region of the framing studs.
- While application of caulking between the bottom wall of the drywall board and the vertical upright of the tile flange attempts to address the water leakage water problems noted above, caulking is not a reliable, long-term solution. The application of caulking is typically done by an installer using a manual or powered caulking gun. The ability to apply a proper, uniform-sized bead around the entire periphery of the tile flange is problematic and is dependent on the skill of the installer. In some regions, the installer may apply a caulking bead that is too thick, wasting caulking and potentially causing excess caulking to ooze down the side wall of shower base. In other regions, the installer may apply a caulking bead that is too thin to provide an adequate seal to inhibit water migration into the gap between the bottom edge of the drywall board and the tile flange. Additionally, over time, caulking tends to lose flexibility, stiffen and deteriorate, compromising the water seal provided by the caulking bead.
- What is needed is an improved water seal between the tile flange of a shower base and the bottom wall of the drywall boards overlying the tile flange that is easier to install and less dependent upon installer skill than application of a caulking bead.
- In one aspect, the present disclosure concerns a combination of a tile flange of a shower base or bathtub and an elongated, flexible sealing member attached to the tile flange. The combination includes the tile flange having a horizontally extending base and an upright projecting vertically upwardly from the horizontally extending base, the upright defining an inner wall and an outer wall spaced from the inner wall and an upper edge of the upright bridging the inner and outer walls. The combination further includes the elongated, flexible sealing member including a lower portion, an upper portion laterally offset from the lower portion and a central lateral section bridging the lower portion and the upper portion, the lower portion including an inner wall and an outer wall and adhesive material affixed to outer wall, the adhesive attaching the lower portion of the sealing member to the inner wall of the upright of the tile flange and defining a seal between the sealing member and the tile flange, the central lateral section of the sealing member overlying the upper edge of the upright of the tile flange, and upper portion extending vertically above the upper edge of the upright.

FIG. 10 is a schematic perspective view of a bathtub including a tile flange extending upwardly from one side of the bathtub. - A shower stall is shown generally at 10 in
FIG. 1 . Only a lower portion of theshower stall 10 is shown since the present disclosure concerns the lower portion of theshower stall 10, an upper portion of the shower stall being of conventional design as would be understood by one of skill in the art. Theshower stall 10 defines aninterior region 12 to be occupied by a person taking a shower and further defines an exit/entry opening 14 for the person to enter and exit the shower stallinterior region 12. In one exemplary embodiment, the shower stallinterior region 12 is generally U-shaped when viewed in horizontal cross section. Theshower stall 10 includes ashower base 100, adrywall board enclosure 200 and a finished board surround 300. The shower stall also includes an elongated,flexible sealing member 400 of the present disclosure which advantageously provides a water resistant seal between theshower base 100 and thedrywall board enclosure 200. - The
shower base 100 includes afloor 102, aside wall 110 extending upwardly from thefloor 102, and athreshold 140 which defines a portion of the entry/exit opening 14 of theshower stall 10. Thefloor 102 provides a standing region for a person using theshower stall 10. Thefloor 102 includes adrain 104 which supports adrain pipe 106 to allow water from the showerhead (not shown) to exit theshower stall 10. Thethreshold 140 includes anouter wall 142 and aninner wall 144 bridged by a step-over 146. A person using theshower stall 10 will step over thethreshold 140 to enter or exit theinterior 12 of theshower stall 12. A vertical height (labeled TH inFIG. 3 ) of thethreshold 140 may be slightly lower than a vertical height SWH of theside wall 110 to allow for ease of entry and exit into theshower stall 10. A shower door or shower curtain (not shown) is typically mounted at the entry/exit opening 14 so as to block water from escaping or splashing out of the interior region while a person is taking a shower in theshower stall 10. - The
shower base 100 further includes theside wall 110 which is generally vertical or more accurately states slope upwardly from thefloor 102 in a generally vertical direction VD (FIG. 3 ). Theside wall 110 includes alower transition region 112 between thefloor 102 and theside wall 110. Anupper portion 112 of theside wall 110 defines an L-shaped tile flange 120. Thetile flange 120 extends around theshower base 100 except for thethreshold 140. Thus, in the exemplary embodiment shown inFIGS. 1-5 , thetile flange 120, when viewed in top plan view is generally U-shaped, extending or having a longitudinal extent running between afirst end 139 a (FIG. 1 ) and asecond end 139 b. Thetile flange 120 includes a generally horizontally extendingbase 122 and an upright 130 extending generally vertically from thebase 122. Thevertical upright 130 includes aninner wall 132 and anouter wall 136 that is spaced from but generally parallel to theinner wall 132. Theinner wall 132 defines a facing 134 that faces toward or in the direction of theinterior region 12 of theshower stall 10. An upper wall orupper edge 138 bridges the inner andouter walls - The
drywall board enclosure 200 comprises a plurality of pieces of a drywall board 101 placed in side-to-side arrangement to form thedrywall board enclosure 100. In one exemplary embodiment of theshower stall 10 of the present disclosure, three pieces ofdrywall board drywall board enclosure 200, as best seen inFIG. 1 . As noted previously, thedrywall board 201 may be any number of drywall board materials suitable for shower installations, thus, drywall board 210, as used herein, will be used to refer generally to any selected drywall board. Theshower stall 10 is supported by a set of framing studs 20, typically conventional 2″×4″ studs. The set of framing studs 20 include a plurality ofstuds 22 positioned horizontally to support theshower base 100 and a plurality ofstuds 24 positioned vertically in spaced apart relation to support thedrywall board enclosure 200 and thefinished wall surround 300. The plurality ofvertical studs 24 are supported by three studs 26 (FIG. 1 ) that lay on their respective sides, flat on asubfloor 30. The plurality ofhorizontal studs 22 also rest on thesubfloor 30. As shown inFIG. 3 , thefloor 102 ofshower base 100 is supported by the subfloor 30 and a layer ofbedding 32 disposed between the subfloor 30 and thefloor 102 of theshower base 100. - The
finished wall surround 300 is typically affixed to thedrywall board 201 and/orvertical framing studs 24 supporting theshower stall 10. Thefinished wall surround 300, with theshower base 100 and a shower ceiling (not shown) defines theinterior region 12 of theshower stall 10. Thefinished wall surround 300 may comprise a single or multiple plastic or fiberglass panels or may comprise a plurality of tiles affixed to thedrywall board enclosure 200. In one exemplary embodiment of theshower stall 10, thefinished wall surround 300 includes threefinished wall panels finished wall surround 300 may comprise a single contoured panel. As used herein, the term finishedwall 301 will generally refer to the one or more panels or plurality of tiles that comprise thefinished wall surround 300. Thefinished wall 301 includes aninside wall 302 that defines a portion of the inner surface of theshower stall 10 and anoutside wall 304 that is adjacent theinside wall 202 of thedrywall board 201. Alower portion 308 of thefinished wall 301 defines a lower wall or edge 306 of thefinished wall 301. - In one exemplary embodiment, sealing
member 400 of the present disclosure comprises a flexible, elongated sealing strip or sealingtape 402 comprised of a polymer/plastic material, such as, for example, PVC, or similar material exhibiting characteristics of being waterproof, flexible, and durable. The sealingmember 400, in one exemplary embodiment, may be fabricated by extruding the polymer material in a conventional manner and then applying the anadhesive strip 440 andadhesive backing 442 to the sealingmember 400. In one exemplary embodiment, the sealingmember 400 has a durometer hardness value of approximately 65 shore. The sealingmember 400 includes aninner wall 404 and a generally parallelouter wall 406. The sealingmember 400 runs or extends along from afirst end 450 to asecond end 452 along a longitudinal axis LA. A length L of the sealingmember 400, as manufactured, is a nominal length providing sufficient length to extend along an entirety of a length of theU-shaped tile flange 120, when affixed to thetile flange 120 starting at the first end of thetile flange 139 a and proceeding to theopposite end 139 b of thetile flange 120 for ashower base 100 of the largest conventional size. - As installed on the
tile flange 120, the length L of the sealingmember 400 may be trimmed to a shorter length, i.e., an installed length LI of the sealingmember 400. The installed length LI is shown schematically inFIG. 6 , that is, the installed length LI is shorter by a trimmed length LX than the original, as manufactured length L of the sealingmember 400. The trimmed length LX of the sealingmember 400 is simply cut off and discarded by the installer. When installed on thetile flange 120, thefirst end 450 of the sealingmember 400 is aligned and congruent with thefirst end 139 a of thetile flange 120. The sealingmember 400 then continues to be applied to the perimeter of thetile flange 120 until thesecond end 139 b of the tile flange is reached. At that point, any excess or trimmed length LX is cut off such that an “as installed”second end 454 of the sealingmember 400 is aligned and congruent with thesecond end 139 b of thetile flange 120. Further, the installed length LI of the sealingmember 400 corresponds to the extent or length of theU-shaped tile flange 120 and the sealingmember 400 conforms to the configuration of theU-shaped tile flange 120 to provide a water resistant seal between thelower portion 410 of the sealingmember 400 and thevertical upright 130 of thetile flange 120. - As can best be seen in
FIGS. 6-8 , looking at the sealingstrip 402 along a vertical central axis VA and a horizontal central axis HA, both of which are orthogonal to the longitudinal axis LA, the sealingstrip 402 includes alower portion 410, anupper portion 430 and a middle or centrallateral portion 420. Thus, as can be seen in the cross section ofFIG. 8 , theupper portion 430 is offset laterally from thelower portion 410 by an extent of themiddle portion 420 taken or measured along the horizontal central axis HA of the sealingstrip 402. - As manufactured, the sealing
member 400 has folds or ceases that differentiate and provide a boundary between thelower portion 410, themiddle portion 420 and theupper portion 430. That is when taken out of the package, the sealingmember 400 is not totally flat but rather has clear bounds and creases between theportions tile flange 120. When installed, the sealingmember 400, has the general offset configuration show in the cross section ofFIG. 8 , that is, thelower portion 410 of the sealingmember 400 is aligned with and seals against thevertical upright 130 of thetile flange 120, the lateralmiddle portion 430 of the sealingmember 400 is aligned with and seals against the upper edge orwall 138 bridging the inner andouter walls vertical upright 130 of thetile flange 120 and is aligned with and seals against thebottom wall 208 of thedrywall board 200, and theupper portion 430 of the sealingmember 400 is aligned with and seals against theoutside wall 204 of thelower portion 206 of thedrywall board 200. Optionally, theupper portion 430 of the sealingmember 400 may be affixed to the plurality ofvertical studs 24 using fasteners such as staples, nails, screws or the like. As can best be seen inFIG. 4 , thelower portion 308 of thefinish wall 301 extends below the sealingmember 400 and terminates at a lower wall or edge 306 that is just above thehorizontal base 122 of the L-shapedtile flange 120. - If the sealing
member 400 were laying flat and was measured along the vertical central axis VA, in one exemplary embodiment, the sealingmember 400 would have an overall vertical height of approximately 2.00 inches. As installed and as shown inFIG. 8 , in one exemplary embodiment, the sealingmember 400 would have an install height SMH of approximately 1.85 inches. As shown inFIG. 8 , in the exemplary embodiment, the vertical height HLP of thelower portion 410 is approximately 0.45 inch, the vertical height HMP of themiddle portion 420 is approximately 0.04 inch and the vertical height HUP of theupper portion 430 is approximately 1.36 inches. Generally, a width of theupper portion 430 of the sealingmember 400 is less that a width of the lower andmiddle portions member 400. In one exemplary embodiment, the width of the lower andmiddle portions member 400 is approximately 0.044 inch and the width of theupper portion 430 is approximately 0.031 inches, as it is desired for sealing and ease of installation purposes, that the bottom andmiddle portions upper portion 430. - When the sealing
member 400 is install on and affixed to thevertical upright 130 of thetile flange 120, anouter surface 412 of thelower portion 410 of the sealingmember 400 faces thetile flange 120. Accordingly, to facilitate attachment and water resistant sealing between thelower portion 410 of the sealingmember 400 and thevertical upright 130 of thetile flange 130, theouter surface 412 of thelower portion 410 includes the adhesive layer orstrip 440 running the extent or length L of the sealingmember 400. In one exemplary embodiment, theadhesive strip 440 is comprised of acrylic foam tape or other adhesive material of similar characteristics. A width of theadhesive strip 440, in one exemplary embodiment, is approximately 0.050 inch. To facilitate installation and to keep debris from adhering to theadhesive strip 440 prior to installation, theadhesive strip 440 is covered by the thinadhesive backing 442. Theadhesive backing 442 is stripped away fromadhesive strip 440 in sections (as described below) by the installer as the installer applies the sealingmember 400 to the tile flange commencing at oneend 139 a of the tile flange and moves along the extent oftile flange 120 to thesecond end 139 b of thetile flange 120. - As can best be seen in
FIG. 10 , when installing the sealingmember 400 to thetile flange 120, the installer begins at thefirst end 139 a of thetile flange 120 and strips off a first section of theadhesive backing 442 from theadhesive strip 440 at thefirst end 450 of the sealingmember 400. A length of the stripped first section will depend on the preference of the installer, but typically will be on the order of 6-18 inches. The installer aligns thefirst end 450 of the first stripped section of the sealingmember 400 with thefirst end 139 a of thetile flange 120 such that the sealing memberfirst end 450 is congruent or flush with the tile flangefirst end 139 a and then further aligns thelower portion 410 of the stripped off section of the sealingmember 400 with thevertical upright 130 of thetile flange 120 such that themiddle portion 430 of the sealingmember 400 overlies and rests upon the upper edge orwall 138 of the tile flange 120 (as shown inFIG. 3 ). The installer then presseslower portion 410 of the first section of the sealingmember 400 against the tile flange upright 130 to affix theadhesive strip 440 and thereby thelower portion 410 of the sealingmember 400 to the tile flange upright 130 thereby forming a seal between the sealingmember 400 and thetile flange 120 and, more specifically between thelower portion 410 of the sealingmember 400 and thetile flange upright 130. - After installation of the first section of the sealing
member 400, the installer then proceeds to strip theadhesive backing 442 from theadhesive strip 440 from a second section of sealingmember 400 that is adjacent to the first section, already installed on thetile flange 120. The installer aligns thelower portion 410 of the second stripped section of the sealingmember 400 with thevertical upright 130 of thetile flange 120 such that themiddle portion 430 of the sealingmember 400 overlies and rests upon the upper edge orwall 138 of thetile flange 120. As before, the installer then presseslower portion 410 of the second section of the sealingmember 400 against the tile flange upright 130 to affix theadhesive strip 440 to the tile flange upright 130 thereby forming a seal between the sealing memberlower portion 410 and thetile flange upright 130. - The installer continues to repeat the installation method described above for stripping the
adhesive backing 442 from theadhesive strip 440 for a section of the sealingmember 400 and then applying the stripped section to thetile flange 120 until thesecond end 139 b of thetile flange 120 is reached. At that point, the installer cuts or trims the sealingmember 400 to the installed length LI of the sealingmember 400 such that the installedsecond end 454 of the sealingmember 400 is flush with thesecond end 139 b of thetile flange 120. - When the sealing
member 400 is applied to thetiling flange 120, as can be seen inFIG. 4 , the middlelateral portion 420 of the sealing member rests on the upper edge orwall 138 of thetile flange 120 and theupper portion 430 of the sealingmember 400 extends above thetile flange 120 and lays against the plurality ofvertical studs 24. Optionally, to keep theupper portion 430 of the sealingmember 400 in the proper vertical orientation against the plurality ofvertical studs 24 when thedrywall board 200 is being installed, the sealing memberupper portion 430 may be affixed to some or all of the plurality ofvertical studs 24 with fasteners. - Next, as best seen in
FIG. 4 , thedrywall boards 201 are installed to the plurality ofvertical studs 24 such that thebottom wall 208 of eachdrywall board 201 contacts and presses against the middlelateral portion 420 of the sealingmember 400. In this way, thebottom wall 208 of thedrywall board 201 and the upper edge orwall 138 of thetile flange 120 contact and sandwich the middlelateral portion 420 of the sealingmember 400 between thedrywall board 201 and thetile flange 120 thereby creating a water resistant seal between alower surface 422 of the middlelateral portion 420 of the sealingmember 400 and theupper edge 138 of thetile flange 120 and between anupper surface 424 of the middlelateral portion 420 of the sealingmember 400 and thebottom wall 208 of thedrywall board 201. Additionally, an inner surface 432 (FIGS. 5 and 9 ) of theupper portion 430 of the sealingmember 400 contacts and seals against theoutside wall 204 of thedrywall board 201 for further water resistance impeding the ingress of water into the region of the set of framing studs 20. The water resistant seals between the sealingmember 400, thetile flange 120 and thedrywall board 201, as described above, provide an improved water resistant seal between thetile flange 120 of theshower base 100 and thelower portions 206 of thedrywall boards 201 of thedrywall board enclosure 200 overlying thetile flange 120, as compared to the traditional application of a caulking bead between thetile flange 120 andbottom wall 208 of thedrywall boards 201. The sealingmember 400 additionally is easier to install on thetile flange 120 and is less dependent upon installer skill than traditional application of a caulking bead between thetile flange 120 andbottom wall 208 of thedrywall boards 201. - The sealing
member 400 can be used in any shower or bathtub installation wherein theshower base 100 or bathtub 1000 (FIG. 10 ) includes atile flange 1002. As can be seen inFIG. 10 , thebathtub 1000 includes an L-shapedtile flange 1002 extending upwardly from an upperplanar surface 1004 along oneside 1006 of thebathtub 1000. Depending on the design of the bathtub, the L-shapedtile flange 1002 may additionally extend around afront side 1008 and/or aback side 1010 of the bathtub. - As would be appreciated by one of skill in the art, depending on the specific height and length of the L-shaped
tile flange 1002 of the bathtub 1000 (or the specific height and length of thetile flange 120 of the shower base 100), the specific overall vertical height, the installed height SMH, the upper portion height HUP, the middle portion height HMP, the lower portion height HLP and the width of W of the sealing member length L may be modified as required. Since in one exemplary embodiment, the sealingmember 400 may be fabricated by extruding a polymer material, such as PVC, changing the dimensions of the sealingmember 400 can be readily accomplished. - As used herein, terms of orientation and/or direction such as up, down, upward, downward, inside, outside, etc., are provided for convenience purposes and relate generally to the orientation shown in the Figures and/or discussed in the Detailed Description. Such orientation/direction terms are not intended to limit the scope of the present disclosure, this application, and/or the invention or inventions described therein, and/or any of the claims appended hereto. Further, as used herein the terms comprise, comprises, and comprising is taken to specify the presence of stated features, elements, steps or components, but does not preclude the presence or addition of one or more other features, elements, steps or components.
- What have been described above are examples of the present disclosure/invention. It is, of course, not possible to describe every conceivable combination of components, assemblies, or methodologies for purposes of describing the present disclosure/invention, but one of ordinary skill in the art will recognize that many further combinations and permutations of the present disclosure/invention are possible. Accordingly, the present disclosure/invention is intended to embrace all such alterations, modifications, and variations that fall within the spirit and scope of the appended claims.
