How to Install Mortar Shower Pan Membrane Liner
Once you've framed the shower stall, it is time to install the pan liner and cement backer board to create a water tight seal.
Remove the drain cap and tape over the drain to keep mortar and other debris from entering the drain. Put down a layer of felt paper to help prevent moisture from wicking down through to the subfloor. Place a layer of metal lathe over the felt paper. Trowel in a layer of mortar that it has a one quarter inch slope towards the drain. Once the mortar dries, place a layer of felt paper along the walls of the shower stall. Attach cement board with the rough side out along the top half of the walls. Install the shower stall membrane in the bottom of the shower so that it overlaps in the corners, covers the shower curb and is approximately six inches up the side of the walls. Cut out holes for the drain, the drain bolts and the weep holes. Seal the underside of the membrane near the drain with silicone. Nail the membrane that covers the curb only on the outside. Attach the remaining cement board leaving one inch clearance from the bottom. Caulk all seems. Place some pebbles near the weep holes to protect the openings. Trowel in a layer of mortar that has a one quarter inch slope towards the drain. Mortar the curb. Remove the tape from the drain.
The floor should be floated a minimum of 1 1/4" around the drain with dry pack mortar. A slope of 1/4" per ft from the drain to the perimeter is also necessary. Even more important than the slope of the drypack on top of the liner is a pre-slope under the liner or hot mop to achieve proper drainage. Also, make sure to clear out the weep holes and use either spacers or crushed tile to put on top of weep holes before floating pan for proper drainage. Well, there you go. A ample draining, properly floated shower pan.
No.
I'm going to presume that it already had a liner in it once before.. there are only a few systems like you are describing. One is a stainless steel wall and concrete bottom (.claytonlambert), and the other is a (onlyevolution) composite (not polymer though) wall system that is painted with a painted concrete bottom. I think there is a company called Swimcrete as well.. but, either way, if you wanted to drop in a liner, you'd need to have some sort of coping or beadtrac around the top. If you could post a picture it would be helpful! The answer is "absolutely not"! The liner folks will be happy to sell you a liner, but it will not last 2 years. A hybrid pool lacks the required 'concrete receptor coping' installed in all vinyl liner pool installations. The required concrete receptor coping is extremely strong and contains what is known as a 'bead receptor'. All vinyl liners are manufactured with a 'bead' around the top of the liner. Obviously, at installation the bead is inserted into the bead receptor enabling the liner to support well over a hundred thousand (100,000) pounds of water. Even a small vinyl liner pool, 16x32, holds about 125,000 pounds of water. The vinyl liner salesmen, those without ethics, will nail a track into the top of the polymer wall, then screw the liner into the track. In other words, the 20mil liner with screw holes is expected to hold at least 125,000 pounds. As soon as the ground settles, even a little bit, the liner tears and you're out thousands of dollars. Better is resurface the walls with swimming pool gelcoat.

The RMS QM2 transatlantic ocean liner is also known as the Queen Mary 2. Only one company, out of several companies, won the bid to build the ocean liner, and that company was Chantiers de l'Antlantique of France. The ship was first launched in 2003.
The center of the shower floor where the tile shower drain would normally be positioned ... drain base. After this step the sloped mortar bed should be ... pan liner or membrane in our instructions.

The best and easiest answer to this is to go on-line to Schluter website and see the products they have for ALL your shower building needs. The answer is a Structural foam, pre-pitched base with a "Ditra" liner both produced by Schluter. These products are available from Home Depot and ANY legitamate tile retailer.
Liquid nail,
No, that is not common, but there are many different shower pans, so mistakes are possible.

a shower curtain goes on the outside and a shower liner goes on the inside so the shower curtain wont get wet
Not that I know of...the shower liner should be below the dry pack mortar bed, and stays in place when you pack it. If our are putting the dry pack in first, then the liner directly under the tile, you've done it wrong.ANS 2 - The construction adhesive PL200 is commonly used for this, and works very well. I've used it many times on similar jobs to this one.
The best way is to install 6 mil or greater poly sheeting. this will ensure a longer lasting seal.
A shower curtain is for decor and hung on the outside of the bathtub/shower. Whereas a shower curtain liner is hung on the inside of the tub/shower to protect the shower curtain. In simpler terms...SHOWER CURTAIN: gets to hang and look pretty and be dry. SHOWER CURTAIN LINER: protects shower curtain from getting wet because it's the one getting wet!
Yes
Curtain in, liner out.
