AVA WALK IN

INSTALLATION

INSTRUCTIONS

IMPORTANT INFORMATION

Please read all instructions and warranty information before beginning installation.

It is assumed that this instruction is being carried out by qualiﬁed trades-people.

The AVA shower base is a durable product but care must be taken during installation. Rough handling,

impacts to wall ﬂanges and other areas can cause unnecessary breaks which are not covered under

warranty.

Please carefully lift and lower the shower base into position. Suction handles as used by glaziers can

be very useful for this. DO NOT DROP, HIT OR SLIDE SHOWER BASE.

Once out of its freight packaging and after installation we ﬁrmly recommend keeping the surface

covered to remove the risk of unnecessary damage i.e. dropped tools, tiles, glass, paint etc. The

packaging can be easily cut down/modiﬁed to make a covering until work is complete.

2. DRY FITTING THE BASE

• Clean/prepare ﬂoor surface in accordance with directions on adhesive. Check ﬂoor for level

surface, noting any humps and falls. The ﬂoor must be completely clean and free from all dust.

Walls should be plumb.

• Fit the shower base into position by carefully lifting and lowering into place. The shower base

must ﬁt square/plumb to adjacent walls and be rock solid under foot.

• Ensure inside face of the upstand is ﬂush with the Gib (FIG 2).

• If required, us plastic H packers to level shower base in all directions, particularly through the

drain channel (if channel waste model supplied) (FIG 1).

• Once sitting level and in correct position, carefully remove tray. Secure H packers to the ﬂoor to

prevent them shifting when reﬁtting tray.

INSTRUCTIONS

4. FIX THE SHOWER BASE IN PLACE

• Carefully stand shower on edge in vertical position.

• Apply adhesive in continuous parallel 8mm lines

approximately 100mm apart (FIG 5).

• Enough adhesive must be applied to contact with the

floor and when set will provide a full and even support.

• Re-position shower base in place as per dry fit. Check

again for level.

• Seal between top of upstand and bottom of Gib with

silicone, ensuring the inside face of both are flush (FIG 6).

• Allow adhesive & silicone to fully set for at least 8 hours

before standing on the shower base.

5. WATERPROOFING

AVA bases are pre primed so do not need a primer. Crest

Showers recommends applying a waterproof bandage

covering the join between the top of the upstand and the

bottom of the Gib board before applying waterprooﬁng

membrane down to the bottom of the upstand over the base,

down into the waste hole and out to the ﬂoor or as per your

Council’s required application area. However, it is up to your

registered waterproofer’s discretion whether they wish to

follow this recommendation.

INSTRUCTIONS

6A. CENTRE WASTE BASE - INSTALLING

THE WASTE TOP

• Place top waste clamp into recess and down into waste

body then fasten top clamp in place (FIG 5) by ﬁxing

screws. Screws need to be ﬁrm but not over-tight.

• Screw waste lid onto top clamp.

• Put large polystyrene block back in position to protect

base surface.

NOTE: Do not remove protective lid label on waste cover

until end of installation process.

FIG 7A.

6B. CHANNEL WASTE BASE - INSTALLING

THE CHANNEL DRAIN

• Once the water prooﬁng has cured, the tiler will need to

set up the height of the channel waste drain lid to align

with the ﬁnished surface of the selected tiles. This is

achieved by applying large ‘daubs’ of adhesive under

the channel drain to set the ﬁnished channel drain height.

This is to allow any leakage of water beneath the tiles

to be able to work it’s way out towards the waste outlet

under the channel drain. (A solid mass of adhesive

will only trap any water around the channel drain and

potentially cause pooling of water.)

• Position the channel drain on the daubs of adhesive

and check the ﬁnal height is set below the ﬁnished tile

height. Ensure a 15-20mm clearance is around all sides

of the channel drain to accommodate for wall tiles so the

removable lid is able to be removed for cleaning.

GLAZING CHANNELS

7. INSTALLING GLAZING CHANNELS

• Use a 2 meter level to check walls are within 2-3mm of

plumb.

• Clean ﬂoor channels and underside of wall channel with a

dry rag.

• Slide wall channel on top of ﬂoor channel, making sure

they butt up to each other and insert channel connector

inside ‘wall to ﬂoor’ join to help line up the wall channel

(FIG 8).

• When plumb, drill 2 holes (3.5mmD) in wall channel, lining

up with framing locations. (FIG 9). The top hole should

be within 100mm of top of channel and the second hole

within 1000mm of top of channel. No screws will be

required lower than 1000mm up from bottom of base.

• Remove dust from holes and from inside ﬂoor channel.

• Clean underside of wall channel with a dry rag before

running a thick bead (be very liberal to allow overﬂow and

proper adhesion) of silicone in a continuous line down

the entire length of the back of the wall channel (FIG 9)

and place on wall. Pop out channel connector and apply

silicon into the ﬂoor to wall junction, pushing the channel

connector back in once done.

• Inject silicone into and around screw holes (FIG 11). Ensure

wall channel is plumb, then screw in place.

IMPORTANT

As an added waterprooﬁng precaution, you can apply a

continuous bead of silicon down the whole length of wall

channel either on the interior or exterior of the wall channel

as at your discretion.

FIG 10.

FIG 9.

FIG 8.

FIG 11.

IMPORTANT:

PLEASE MEASURE WALL CHANNELS

For walk in showers, wall channels will

measure 1940mm.

If custom panels, your wall channels will

measure 10mm less than your glass height.

9. FINISHING GLAZING CHANEL TO

GLASS PANEL JOIN

• Starting at the top of the wall channel, from outside

shower, spray with warm soapy water then insert rubber

wedge seal into gap (removing plastic wedges if used).

(FIG 16) Leave rubber wedge protruding 40mm at top to

cut o later.

IMPORTANT: Rubber wedge must be pressed into channel

lightly from top to bottom before pushing right in. This

method ensures rubber wedge does not set stretched and

then shrink later.

• Repeat steps 3 and 4 with applicable panels.

FOR GLASS TO GLASS JOINS:

• Apply masking tape down the length of the panel,

allowing a 10mm gap for the glass to butt into for the

glass to glass join (FIG 17).

• Run a continuous bead of silicon down entire length of

10mm face of installed wall to glass panel and across

ﬂoor channel to the width of the glass to glass panel (FIG

18).

• Gently place glass to glass panel into siliconed ﬂoor

channel and tilt gently upwards until it joins to glass

to wall panel (FIG 19). Ensure there is no side to side

movement while placing panel as this will smear silicone.

• Hold glass to glass join in place with masking tape.

• Cut o excess rubber wedge.

• Insert AVA door insert into door gap.

• Spray channels and glass with slightly soapy water then

use spatula provided to clean o excess silicone (FIG 20).

Repeat this process 3 times. Use minimal water then wipe

o with paper towels.

10. INSTALLING SHELVES

Crest Showers Floating Glass Shower Shelf can be installed

in any corner of a glass or tile wall. If two shelves are installed

in the same corner, ideal shelf heights o the ﬂoor are 1200 &

1600mm. When installed in dierent corners, an ideal height is

1400mm o the ﬂoor.

When installing onto Seratone, Hardiglaze or Sim, apply masking

tape to the liner then stick the stabiliser block to the masking

tape. This makes the blocks easier to remove and protects the

wall board surface.

We DO NOT recommend installing these on acrylic liners, due to

adhesion diculties.

IMPORTANT: Protect ﬂoor until adhesive has cured in case of

the unlikely event that shelf/shower is disturbed and shelf falls

o.

• Clean area shelf is being adhered to, ensuring it is free of

any dust, soap scum, cleaners or any other substance.

• Remove backing from stabiliser blocks and press ﬁrmly

onto wall (FIG 22).

• Place shelf in position and check for level. Optional -

apply masking tape to shelf/wall (FIG 23).

• Remove shelf and put a thin bead of adhesive down both

edges of shelf (FIG 24).

• Carefully place shelf on stabiliser blocks and gently push

into corner. Check for level (FIG 25).

• Clean up adhesive with spatula. Remove masking tape.

• After 24-48 hours remove stabiliser blocks (FIG 26).
