SHOWER BASE INSTALLATION FOR
ACRYLIC SHOWER WALL APPLICATIONS
a.
For shower wall applications the shower base does not need checking into the
stud wall. It can be simply pushed against the stud frame. The shower base can
be installed before the wet area sheet is applied.
b.
If the shower base is to be installed after the wet area sheet is installed, the wet
area sheet will need to be cut away to allow the base to sit against the stud wall,
allowing a 6mm gap all around the shower base.
c.
Prior to installation remove plastic film from the base and inspect for any damage.
DO NOT COMPLETELY REMOVE THE PROTECTIVE FILM AT THIS STAGE
d.
Qualified tradesperson should assemble the waste and
adjoining plumbing. The waste assembly should be
checked to ensure it’s located centrally in the shower
base waste hole for best appearance. The locking
nut should be kept loose until the Chrome top cover
is located and sits centrally in the hole, with equal
spacing around all sides. Once satisfied, tighten the
lock ring on the waste assembly back and then remove
the chrome waste cover until the end of the installation
for protection.
e.
Ensure the floor surface is clean and dry. Apply a generous amount of building
adhesive to the shower base self-supporting feet - suitable for concrete bond
(adhesive not supplied – eg. Liquid Nails or similar).
f.
Position the shower base against the wall studs and push the shower base
down firmly to bed the feet against the floor. Recheck the shower base level and
conduct a water test to ensure full drainage to the waste. Relevel the base as
required whilst adhesive is still uncured.
g.
Allow the shower base to cure for at least 24 hrs. as per the adhesive
manufacturer’s instructions before installing the wall sheeting. This ensures the
level will not change by standing on it.
h.
Once the shower base bond is fully cured, the wet area sheeting can be
applied over the shower base tile bead as per the relevant wet area sheet
manufacturer’s instructions. The wet area sheet should sit over the top edge
of the tile bead. Ensure the wet area sheet is installed at least 6mm above the
shower base tile bead for expansion.

SHOWER BASE SITE PREPARATION
•
Decina shower bases
do not
require installation on a cement slurry mortar base,
as they are fitted with
self-supporting feet.
•
To ensure proper drainage of water
to the waste and also for correct
installation of an optional Decina
shower screen, the floor area under
the shower base must be flat and level
to within 2mm over the width of the
proposed base installation area.
•
For concrete floor installations,if
the floor installation area is un-even
or un-level, the floor should be
relevelled using a cement based self
levelling compound (eg. ARDEX L292
or similar as per manufacturer’s
instructions).
•
For timber or panel floor installations, it is necessary to first lay a suitable fibre
cement floor underlay sheet (eg. James Hardie Ceramic Tile Underlay or similar
as per manufacturer’s instructions). The underlay must be laid level and all
fixings set flush with the surface to avoid unevenness.
•
Ensure the waste trap hole in the floor is no greater than 200 x 200mm and does
not encroach on the position of the self supporting feet.
•
For timber or panel floor installations, ensure the waste trap hole does not result
in the weakening of the floor, as the Decina shower base does not form part of
the building integrity. If weakened, the opening should be suitably reinforced to
provide a structurally sound and flex resistant floor once complete.
•
Before the shower base can be installed, the choice of wall construction and
wall lining method must be determined. The choice will determine which of the
following methods should be followed:
200mm max
200mm max
200mm max
