Newbie question about shower pan

Hi Guys,

I am currently re-doing the shower as it was leaking, i have pulled the tiles off the floor and walls. I'm currently chiseling up the thin set and what I thought should be the mortar bed. I have taken a picture of where I'm at, just not sure if its the actual concrete slab or mortar bed. It seems very firm with small jack hammer.

If you someone could please take a look and let me know, that would be greatly appreciated.

Looks like a original mud bed with the liner exposed on the left side. They can be just as hard as concrete. There should be a liner under it, whats below?, joists and framing? Also the drain hieght position and construction of the wall, though i'm not sure why the concrete between the studs is there, unless for liner support

That liner appears to only be a 6 mil vapor barrier, which won't cut it as a pan liner, either. From all appearances this seems to only be an inch or so deep. You will need to remove the tiles on the short wall to the right as well, since your new liner will need to extend up the walls and over any berms you build.

We usually refer people to a site such as this when they are contemplating a new pan build, since it is a step by step instruction tutorial. How to build a shower - Building a shower pan with pre-sloped mortar bed, liner and curb.
