Description
SHOWER BASE
The invention relates to a shower base module for constructing a tiled shower, and
methods of constructing a tiled shower using the shower base module.
Conventional methods for manually building a tiled shower base are complicated and
time-consuming. A frame for the shower pan is firstly constructed on the subfloor, typically out
of wooden blocks. The frame is carefully filled with mortar, ensuring that the base slopes
towards the shower drain, and the mortar is then left to harden overnight. A waterproofing liner
is attached on top of the mortar, and a hole cut in the liner to accommodate the shower drain. A
further layer of mortar may need to be applied before the tiles can be installed.
More recently, prefabricated shower bases have been designed to simplify installation
and improve the water-resistance of the shower areas. The prefabricated shower base essentially
replaces the mortar and liner layers, such that once the prefabricated shower base is installed onto
the subfloor of a building and the drainage aperture connected to a drain pipe, the shower area
may be tiled directly, without the need to apply mortar.
However, conventional prefabricated shower bases still suffer from waterproofing
issues. Inevitably, cracks will form in the tiled floor due to settling or other movement of the
building. Water that seeps through the cracks is captured and contained on the prefabricated
shower base. While most of the water will generally drain into the drainage aperture, it has been
found that some water can remain pooled at sections of the shower base, promoting rot and mold
within the floor. Further, it has been found that the area around the drainage aperture of the
prefabricated base is prone to defects and leaks.
In this context, there is a need for prefabricated shower bases with improved
waterproofing properties.
According to an aspect of the present invention, there is provided a shower base
module for constructing a tiled shower, the shower base module comprising:
a base portion on which tiles are to be subsequently installed, the base portion comprising
a drainage aperture, wherein a top surface of the base portion slopes downwardly towards the
drainage aperture and wherein the top surface comprises a plurality of drainage grooves, each
groove leading into the drainage aperture;
flashing extending upwardly from one or more sides of the base portion.
The drainage aperture may comprise an elongate aperture.
The shower base module may comprise an annular aperture.
The shower base module may further comprise a tray at an underside of the base
portion and encompassing the drainage aperture to capture fluid entering the drainage aperture,
wherein the tray comprises a drainage port connectable to a drain pipe for draining the captured
fluid.
The shower base module may further comprise a mesh insert positioned across the
drainage port of the tray.
The shower base module may further comprise a drainage channel structure
positioned on or within the drainage aperture.
The top surface of the base portion may further comprise a rebate defined around the
drainage aperture for receiving edge portions of the drainage channel structure.
The drainage channel structure may comprise a plurality of slots or recesses
configured to be in fluid communication with adjacent portions of the drainage grooves.
The shower base module may further comprise a drainage cover plate positioned
above or within the drainage channel structure.
The drainage cover plate may be invertible to provide a tray for receiving one or
more tile portions.
At least one drainage groove may extend from each edge of the base portion and lead
into the drainage aperture.
The top surface of the base portion may further comprise edge drainage grooves
along or adjacent a perimeter of the base portion, wherein the edge drainage grooves lead into at
least one of said plurality of drainage grooves.
Each drainage groove may be between about 5 mm and about 15 mm wide.
Each drainage groove may be between about 5 mm and about 15 mm deep.
Each drainage groove may be about 10 mm wide and about 10 mm deep.
The slope of the top surface of the base portion may be at least about 10 mm/meter.
The base portion may be formed of a polymeric foam.
A top and/or bottom surface of the base portion may be lined with a waterproofing
membrane.
One or more side surfaces of the base portion may comprise an elongate slot
extending along the side surface for retaining the flashing.
The shower base module may further comprise mesh positioned over each drainage
groove.
The present invention also provides a method of constructing a tiled shower,
comprising:
mounting the shower base module as described to a subfloor of a building, wherein each
flashing of the shower base module is positioned flush against a wall;
connecting the drainage aperture of the shower base module to a drain pipe of the
building; and
installing tiles onto the base portion of the shower base module.
The invention will now be described, by way of non-limiting example only, with
reference to the accompanying drawings, in which:

Figure 1 illustrates half of a shower base module 100 for constructing a tiled shower
according to one embodiment. The front half of the shower base module is of a similar
configuration and has been cut away in Figure 1 to provide a clearer view of details of the
shower base. The shower base module 100 comprises a base portion 2 on which tiles 30 are to be
subsequently installed. The base portion 2 comprises a drainage aperture 4 extending through the
entire thickness of the base portion. The top surface of the base portion 2 slopes downwardly
towards the drainage aperture 4. Further, the top surface of the base portion 2 comprises a
plurality of drainage grooves 6, each groove leading into the drainage aperture 4, such that any
water contained in these grooves is drained into the drainage aperture. The shower base module
100 further comprises flashing 8 extending upwardly from one or more sides of the base portion
As shown in the embodiment of Figure 1, the drainage aperture 4 may comprise an
elongate aperture. The elongate drainage aperture may extend along and adjacent an edge of the
base portion 2. In other embodiments, for example as shown in Figure 9, the drainage aperture 4
may comprise an annular aperture. The annular drainage aperture may be located centrally of the
base portion 2. Importantly, regardless of the shape or location of the drainage aperture 4, the top
surface of the base portion 2 slopes downwardly towards the drainage aperture. Preferably, the
amount of slope is at least about 10 mm/meter.
The shower base module 100 preferably also comprises a tray 10 at an underside of
the base portion 2 to capture fluid entering the drainage aperture 4. The tray 10 is sized and
shaped to suit the configuration of the drainage aperture 4, preferably to encompass the entire
drainage aperture as well as a portion of the surrounding base material. The tray 10 therefore
improves the waterproofing properties of the shower base 100 by capturing all water that flows
through the drainage aperture 4 and directing all the water to the drain pipe, even if the base
portion 2 cracks or fails around the drainage aperture 4. For example, Figure 5 illustrates an
elongate tray 12 configured to be positioned at the underside of a base portion 2 and to
encompass the entire length of an elongate drainage aperture 4 and a portion of surrounding
areas, as shown in Figure 4. Figure 11 similarly illustrates a rectangular tray 12 configured to be
positioned at the underside of a base portion 2 to encompass an annular drainage aperture 4 and
surrounding areas, as shown in Figure 10.
The tray 10 may comprise side walls 13 extending upwardly from a base, and a
drainage port 12 defined in the base. The drainage port 12 is connectable to a drain pipe of the
building (not shown) for draining fluid captured in the tray 10. The diameter of the drainage port
12 may be about 100 mm for connection to a standard drainage pipe. In some embodiments, the
drainage port 12 may be about 50 mm in diameter, or an adaptor such as adaptor 31 shown in
Figure 12 may be used to provide a reduced-diameter drainage port 33 of about 50 mm, to allow
for connection to 50 mm pipes where the shower is to be installed on an upper storey of a
building.
In some embodiments as illustrated in Figure 5, tray 10 may comprise one or more
markings 9 provided on the base of the tray as a template for the installer to form (eg drill) a
suitable drainage port 12 during installation. This may be particularly useful for installations on
upper storeys of a building, to enable the installer to configure the position of the drainage port
during installation to suit the position of the existing drainpipe. In some embodiments as
illustrated in Figure 6, a drain pipe mount 15 may be attached to the drainage port 12 to provide
coupling means for the drain pipe. In one example, a top portion 17 of the drain pipe mount 15
may be detachable, to sandwich the tray 10 in between the top portion 17 and the rest of the
mount 15. Seal 19, formed of a suitable elastomeric material such as rubber or a plastics material,
may be provided at this detachable connection to ensure a leak-proof connection between the
drain pipe mount 15 and the tray 10. Preferably, the top portion 17 of the mount 15 and the
drainage port 12 are sized and configured so that when installed, the top portion 17 is flush with
the upper surface of the base of the tray 10.
The tray 10 is formed of any suitably durable, waterproof and lightweight material,
such as a plastics material, eg polyvinyl chloride (PVC), or a corrosion-resistant metal. The tray
may be mounted to the underside of the base portion 2 via any suitable means, for example
using an adhesive. In one embodiment, as illustrated in Figures 7 and 14, cutouts such as slots 11
are provided in the underside of base portion 2 to receive side walls 13 of the tray 10. The side
walls may be sealingly attached within the slots 11 using a suitable sealant. In some
embodiments, the side walls 13 may be about 10 mm to about 15 mm in height, and may extend
about or less than midway into the thickness of the base portion 2 when installed. In other
embodiments (not shown), the tray 10 may be mounted by hanging outwardly extending rim
portions of the tray onto rebate portions 18 defined around the perimeter of the drainage aperture
4, with the body of the tray extending downwardly through the drainage aperture such that the
base of the tray 10 is at the underside of the base portion 2.
In preferred embodiments, as illustrated in Figures 1 and 9, at least one drainage
groove 6 extends from each edge of the base portion 2 to the drainage aperture 4. In some
embodiments (not shown) where the shape of the base portion 2 is circular or one or more edges
of the base portion 2 is/are curved, a suitable number of drainage grooves are preferably provided
extending from the curved edge/circumference of the base portion to the drainage aperture 4. For
example, for a circular base portion 2, four drainage grooves 6 may be provided, one in each
quadrant of the circle.
Further, edge drainage grooves 26 are preferably provided along or adjacent a
perimeter of the base portion 2. The edge drainage grooves 26 lead into at least one of the
drainage grooves 6, to provide a continuous flow path for fluid to drain into the drainage aperture
4. Accordingly, the combination of the sloped top surface, the drainage grooves 6 and the edge
drainage grooves 26 helps to ensure that any water that seeps though the overlying tiles and onto
the base portion 2 will be directed into the drainage aperture 4 and tray 12 and subsequently into
the connected drain pipe, regardless of the location of the leak. It will be appreciated that this
prevents water from pooling at sections of the shower base, thereby improving the waterproofing
properties of the shower base 100.
In preferred embodiments, each drainage groove 6, 26 is between about 5 mm and
about 15 mm wide. In preferred embodiments, each drainage groove 6, 26 is between about 5
mm and about 15 mm deep. For example, the drainage grooves 6, 26 may be about 10 mm wide
and about 10 mm deep. In some embodiments, mesh 29 may be provided to cover the drainage
grooves 6, 26, to prevent debris from entering the grooves during installation of the shower base,
while still allowing water to flow into the grooves in use. The mesh 29 may be formed of any
suitable durable, corrosion-resistant mesh material such as fiberglass. In some embodiments,
removable tape (not shown) may additionally or alternatively be provided to cover the drainage
grooves 6, 26 during installation. The tape may, for example, prevent tile adhesive from entering
the grooves 6, 26 while the adhesive is being applied to the base portion 2, and the tape may be
removed just prior to positioning the tiles onto the base portion.
Components of the drainage fittings provided inside drainage aperture 4 in preferred
embodiments will now be described in more detail, with reference to Figures 7 and 14. A
drainage channel structure 16 is positioned on or within the drainage aperture 4 to define a
drainage channel, and is sized and shaped to suit the configuration of the drainage aperture. For
example, the channel structure 16 may be elongate to fit within the elongate drainage aperture 4
of Figure 1, or may be annular as shown in Figure 13 to fit within an annular drainage aperture 4.
The channel structure 16 is preferably formed of a durable, substantially rigid material to provide
support and/or attachment means for mounting other components such as cover plate 24 to the
shower base module. For example, the channel structure 16 may be formed of a metal such as
aluminum or stainless steel.
In some embodiments, drainage channel structure 16 is positioned on or within the
drainage aperture 4 via outwardly extending edge portions 20 of the channel structure received in
rebate 18 defined on the top surface of the base portion 2 around the drainage aperture 4. The
channel structure 16 may also comprise upwardly extending flanges 21 to provide a tile
positioning guide during installation of tiles 30. The length of the upwardly extending flanges 21
is preferably selected to match the installed height of tiles 30.
In some embodiments as illustrated in Figure 13, the drainage channel structure 16
may comprise a plurality of slots or recesses 22 on the outwardly extending edge portions 20,
configured to be in fluid communication with adjacent portions of the drainage grooves 6. This
way, the channel structure 16 does not obstruct the flow of water through the drainage grooves 6
and into the drainage aperture 4.
In some embodiments, a drainage cover plate 24 is positioned above or within the
drainage channel defined by channel structure 16. The cover plate 24 may comprise grates to
allow water to drain through the cover plate. Additionally or alternatively, as illustrated in Figure
7, the cover plate 24 may be sized to provide a gap 25 between the cover plate 24 and sides of the
channel structure 16, to allow water to pass through this gap into the drainage aperture 4. The
drainage cover plate 24 may be removably supported on channel structure 16 via cover plate
holder 24b, as illustrated in Figure 7. Depending on the length of the channel structure 16, one or
more cover plate holders 24b may be provided, spaced apart from each other along the length of
the elongate drainage aperture 4 to support the channel structure 16. The ability to remove the
cover plate 24 from the cover plate holder 24b allows for the cover plate to be replaced and/or
inverted to provide a tile retaining tray, as described in more detail below. In other embodiments,
the cover plate 24 and cover plate holder 24b may be integrally formed.
In other embodiments, the cover plate 24 may be attached via a height-adjustable
mechanism such as screw threads 27 provided on the base of the cover plate and the inner surface
of the channel structure 16, as illustrated in Figures 13 and 14. The height adjustability allows for
the height of the cover plate to match the installed height of tiles 30, so as to provide a
substantially flush finished surface.
The drainage cover plate 24 may be formed of any suitably durable and corrosion-
resistant material, such as stainless steel or aluminum. In some embodiments, the cover plate 24
may be invertible to provide a tray for receiving and retaining one or more tile portions, to match
the surrounding tiled area and thereby provide a continuous tiled shower surface.
In some embodiments, a mesh insert 14 is positioned across the drainage port 12 of
the tray 10, to prevent hair and other debris from entering the connected drain pipe. The mesh
insert 14 is accessible by the user for cleaning, for example by lifting cover plate 24 (and cover
plate holder 24b if provided). In some embodiments, the mesh insert 14 may be removable for
cleaning. Alternatively, the mesh insert may be attached to or integral with drainage channel
structure 16.
The base portion 2 is preferably formed of a lightweight, waterproof and durable
material such as a closed-cell polymeric foam, eg expanded polystyrene foam. The foam material
is selected to ensure adequate adhesion to tile adhesive, and thereby to the overlying tiles. To
increase water-resistance, one or both of the top and bottom surfaces of the base portion 2 may
additionally be lined with a waterproofing membrane. In some embodiments, the waterproof
membrane is selected to improve binding to tile adhesive.
Flashing 8 prevents water contained on the base portion 2 from seeping onto
surrounding walls. The flashing 8 also provides a secondary water barrier, for example in case of
minor flooding, some volume of water can be temporarily retained within the sink defined by the
base portion 2 and the surrounding flashing 8. The number of side surfaces of the base portion 2
which require flashing 8 depends on the intended installation location of the shower base.
Generally, flashing 8 should be provided as a barrier between the shower base and any adjacent
building walls. Accordingly, flashing 8 is formed of a suitably durable, water-resistant material,
such as PVC. An elongate slot 28 may be provided extending along the side surface of the base
portion 2 and substantially perpendicular to the side surface of the base portion 2, to retain the
flashing 8. Sealant and/or membrane linings such as a silicone membrane may be provided at this
connection to ensure a complete, watertight seal between the flashing 8 and slot 28.
Figure 8 illustrates an optional cosmetic flashing 32 that may be attached to a front
edge of the base portion 2, ie where the shower base is not against a wall. The flashing may be
formed of a suitably durable, corrosion-resistant material such as stainless steel or aluminum.
The cosmetic flashing 32 has an upwardly projecting portion 34 that may be sized to be slightly
higher than the installed height of the tiles 30, to provide a small lip 36 that may help to retain
water within the shower area. When installed, only a top portion 38 of the cosmetic flashing will
be visible at the edge of the shower base.
The present invention also relates to a method for conveniently constructing a tiled
shower using the shower base module 100. In preferred embodiments, the shower base module
100 is mounted to the subfloor of the building. The subfloor refers to the structural flooring layer
over which cosmetic flooring such as tiles will be laid. For example, the shower base module 100
may be placed on a concrete slab subfloor, a plywood subfloor, or composite subflooring, such as
particleboard. The shower base module 100 is positioned such that flashing 8 is flush against the
wall studs, with plaster installed over and/or above the flashing 8. The drainage aperture 4 of the
shower base module 100 is connected to a drain pipe of the building, for example via the
drainage port 12 of tray 10. Tiles or other cosmetic finish may then be installed over the base
portion 2 and the walls of the shower area. If tape is provided to protect the drainage grooves 6,
26 during installation, the tape may be removed after tile adhesive is applied to the base portion 2
and before the tiles are positioned onto the base portion.
Each shower base module 100 may be manufactured to the user's required
specifications. Alternatively, multiple different configurations of the present shower base may be
manufactured for sale. In this way, the entire shower base module may be prefabricated and fully
tested for leaks prior to being sold and installed. It will be appreciated that the modularity of
various embodiments of the present shower base facilitates this customization. For example, the
number of flashings 8 may be selected depending on the number of surrounding walls of the
shower area. The height of the tile positioning flange 21 of drainage channel structure 16 and the
height of the upwardly projecting portion 34 on cosmetic flashing 32 may be selected to suit the
intended height of the installed tiles. Further, cover plate 24 may be height adjustable, as
discussed above, to accommodate different tile heights.
While various embodiments of the present invention have been described above, it
should be understood that they have been presented by way of example only, and not by way of
limitation. It will be apparent to a person skilled in the relevant art that various changes in form
and detail can be made therein without departing from the spirit and scope of the invention.
Thus, the present invention should not be limited by any of the above described exemplary
embodiments.
The reference in this specification to any prior publication (or information derived
from it), or to any matter which is known, is not, and should not be taken as an acknowledgment
or admission or any form of suggestion that that prior publication (or information derived from
it) or known matter forms part of the common general knowledge in the field of endeavor to
which this specification relates.
Throughout this specification and the claims which follow, unless the context
requires otherwise, the word "comprise", and variations such as "comprises" and "comprising",
will be understood to imply the inclusion of a stated integer or step or group of integers or steps
but not the exclusion of any other integer or step or group of integers or steps.
