Not the plumber, but for one you have screws into the backer board very close to the floor. They probably go through the liner which is a big no-no.

You also have screws through the top of the curb which definitely go through the liner. Again, big bad.

If this were my shower, I would look at wrapping the whole thing in a membrane like Kerdi. You can also incorporate you bench this way as well. The one thing I don't know (and hopefully the plumber will return to answer), is if you can bond the Kerdi membrane to the PVC pan liner. Google says Kerdi-fix will do the trick, but I'd do more research if it were me.

Here's a great 15 minute video on how to completely waterproof your shower: https://www.youtube.com/watch?v=9hPMWc22oK8

PS. get that gravel off of the liner before someone steps on it and pokes a hole.
