6.  After  the  bedding  material  has  been 
poured  and 
before
  it  sets,  place  the 
shower  base  into  the  position  with  the 
drain  assembly  sliding  over  the  PVC 
waste pipe.  It will be  necessary to  push 
the shower base until the top of the tile 
flange  aligns  with  the  marks  drawn  on 
the  studs  and  the  front  edge  is 
contacting  the  rough  floor  along  the 
entire length of the shower base. Ensure 
that the  base  is  level in  all directions. 
You may need to use shims to hold the 
tray  level  until  the bedding  fully sets. 
Remove all excess mortar. 
See Fig. 7 for details. 
7.  Allow the bedding material to completely harden before applying weight to the bottom of the 
shower base. 
Install the cement board (or the wallboard) above the tile flanges and secure it to the studs. 
Put the tiles (or other finishing wall material) over the cement board leaving 1/8” gap between 
the bottom of the tile or wall kit and the shower base. Use caulk to fill the gap. 
See Fig. 8 and Fig. 9 for details.
