Patty, what was that answer??????? some other post maybe?

That was from another post. Swanstone wants the backer board behind the lip and the little bit of tile over the lip and caulk the edge. Something about water wicking up into the cbu.

So you have solved all the drain issues , right? Structolite is a GSP version of plaster. Your Swanstione allows you to use several different products to set the pan so it will not flex or creak. You could use DAP caulking adhesive too but I perfer modified thinset found in the tile section of the store. A small 1 gal. bucket is more than enough, plut down a baseball sized scoop evenly placed about 6" apart all over the floor and lower the shower pan into place. Walk around inside the pan for a minute or two and then leave it alone for a day. The modified thinset will harden slowly over the next few days and will not become brittle. I buy premixed thinset in a plastic tub for about $18, not down put thinset down dry, buy wet or mix it yourself.

I used the modified thinset and mixed it wetter than normal and just spread it out. Wish I had this post before I did it... sounds much easier. The shower floor is very level and I just cut the pvc and installed it and the drain. Poured some water later and it drained really fast and no water was left anywhere in the stall.
Thanks again.

I have run into so many problems like this in older houses. They were built without the benefit of ever having to fix or change anything . I once had a home that used 3" copper as the main drain to the septic BURIED in the concrete slab. Well over time the copper rotted and the pipe actually was the concrete "tube" that was left. That customer was not happy when I had to chop all of that floor up to fx the floor where it had collapsed and then run a new main drain around the perimeter of the house.

Bestr bet here is to just take some time with a few fittings in hand and LOOK AT what you have and what you can devise to move it that small amount.
Good Luck

Got it done!! Took 2 street 90's and lined right up! Shower floor is now installed completely. Will let mortar bed cure and then time to tile the walls. In the meantime I will tile the bathroom floor.
Thanks,
Patty
