Make this level line all the way around the shower and install the mortar to this line all the way around the shower. Your slope may be greater in some areas of the shower but you will have a level line to start your all tile at later on.

Always round up. Mix the mortar, place it on the wire mesh and form the slope using a trowel and a piece of wood cut approximately long enough to reach from the mark around the perimeter to the top of the drain assembly. Let the mortar set for a day to harden. After 24 hours the mortar will still be green and you will be able to chip it and scratch it, this is normal.

Let the pvc shower pan liner run up the walls above the 2x8 blocks around the perimeter. Make sure it goes over the curb at the shower entry and down to the floor in front of the curb. Feel for the bolts at the drain and use the utility knife to cut a X over each bolt. Then press the PVC liner down over the bolts. Locate the drain between the bolts by pressing down in the center of the drain. This will reveal where the edges of the drain are. If there are weep holes on the flange you will need to cut out around them so the water will be able to flow past the liner and into the drain.

To check for leaks in the membrane, plug the drain hole with an expandable stopper, which you can purchase at a hardware store.
Fill the pan with water to about an inch from the top of the membrane. Let the water come to rest, mark its level on the side of the pan, and let the water sit for 24 hours. Then check the level.
If it's still at the mark, the pan is watertight. If the water is below the mark, the membrane has a leak somewhere. Check the surrounding floor for water, which would have come from a leak in the side.
If there's no evidence of water, pull the plug, expand its diameter a little, and repeat the test. If the water has drained out completely, it's probably leaking at the drain flange, which is either too loose or too tight and may have cut the membrane. Tighten the bolts if they feel too loose. If the flange has cut the membrane, remove the drain plate, let the membrane dry completely, and solvent-weld a patch at least 2 inches larger than the puncture.
