Step 1
When the shower pan is sitting on the ground, any side that touch the wall there is a 1 1/2" lip that flare upwards to prevent leaking into the wall and to mount the shower pan to the studs. On the wall if its tiles you take out the first row from the bottom. Mark 2" along the top of the shower pan, cut it away and unscrew the mounting bolts from the studs

Step 2
If you can not disassemble the old drain from the pan, drill a 1" hole by the drain, use the jig saw and cut around the drain. Pry the pan up from the floor and take it out. Looking at the drain if you have a slap floor you should have a dry well for the drain line, if you have a crawl space you have to go under, dig out some of the dirt and cut the drain line to fit a coupling on the new extension without the new shower pan drain touching it when its installed if the drain line is cast iron you might have to cut the shower drain with the jig saw on both side(splitting it in two)to take it off the line.

Step 3
Before putting the tub down, extend the drain up pipe if you cut it. Put some plumbers putty underneath the top lip of the drain without the rubber seal gasket and the lock nut, slide the drain into the drain hole from the top, underneath the shower pan slide the rubber seal over the drain then the paper gasket then hand tighten the lock nut until it touch the gasket, use the big channel lock plier to tighten the lock nut but do not over tighten it.

Step 4
Measure from the distance from the floor to the top of the shower pan drain then subtract 1/2" and cut the drain line. Its always better to try fit all the connection before final glue down or tightening. Mix up some cement mortar mix and spread it 6" around the edge of the drain' s dry well. You only need maybe 2" thick ring of mortar cement. Step and push the shower pan down until it sit flat on the floor.

Step 5
Inside the shower drain there's suppose to have a rubber seal between the drain and the drain pipe, tighten the seal in with the seal' s nut. Now you can mount the shower pan to the wall with screws, patch the dry wall back, reinstall tiles.
