5. Spread your mortar base (should be a milk shake consistency), evenly 
across the subfloor at the thickness calculated in Step 4.
6. Oset the mortar base 1“ from each outside edge of the pan with 
exception of the curb side. Mortar will protrude out from under the curb, 
run the finishing trowel along curb face to backfill any excess mortar. 
Mark a line on a shim denoting the distance calculated in Step 4. Use the 
shim as a depth gauge to verify that the mortar bed 
is the depth you need.
7. If there is access from the subfloor below and you followed Step 3a, 
then brush primer and PVC adhesive on the inside of the drain and 
outside of the cut drain pipe and quickly insert into drain connection, then 
be sure the drain pipe extends far enough below the subfloor so it can be 
connected to the waste water pipe following the installation.
If there is no access from the subfloor below and you followed step 3b, 
then brush primer and PVC adhesive on the drain pipe stubbed up from 
the subfloor, then quickly insert the stubbed-up drain pipe properly into 
the shower pan drain.**
8. Place the pan in the mud base and firmly but gently shimmy the pan 
(applying pressure in drain location first) into the mud so that (i) the drain 
is fully supported by mud at the bore hole in the substrate, and (ii) the 
ribs are completely filled with the mud alternately applying hand pressure 
to the right and left sides of the pan 
floor until the pan ribs come within 1/8” 
clearance of the subfloor. 
9. Using the level, ensure that the pan is level left to right, and front to 
back along the splash walls. Also make sure the pan is level left to right 
along the curb. 
DO NOT USE THE INSIDE OF THE PAN AS AN
INDICATOR SINCE THE PAN IS PREPITCHED.
DO NOT STEP INTO THE SHOWER PAN ONCE
THE SHOWER PAN HAS BEEN SET AND LEVELED 
UNTIL THE MORTAR HAS CURED COMPLETELY.
