In your first picture, what is the middle layer? I guess that picture is taken from the shower floor pointing at the curb.

You could put a test ball in the drain then put a few inches of water in the shower.

I believe its the liner, concrete board, then the tile.

Its concrete board. They didn't use any waterproofing to seal it. He told me the boards and grout are waterproof. But that part doesn't have grout. I also can't get the shower head in.

There's no way to properly use cement board on the inside and top side of the curb. Fastening the cement board requires screws or nails that would penetrate the liner. It's not done to tile industry standards.

FWIW, cement isn't waterPROOF...it's not damaged by being wetted. The plumbing code calls for NO fasteners through the liner below 2" ABOVE the top of the curb. As said, it's not built to industry standards.

If you did a flood test, yes, it WOULD leak.

This is what we're seeing more and more these days. Installers that don't understand (or care) how the system works and what guidelines to follow.

I wouldn't bother leak testing it. It's going to leak.

Looks like purple board on the walls, in addition to the other problems mentioned.

He's coming back tomorrow to fix some problems. Should I ask him to redo the curb? It wasn't mud or anything just cement board and tile on it. No waterproofing.

Looking at the pictures I would bet there is no waterproofing whatsoever. There should be alkali resistant mesh tape embedded in thinset at all the seams. If there is none at the curb there's a good chance there is none at all. Not only is it going to leak but the grout joints will be cracking within a week.

Looks like the installer is fairly competent at making the work look ok but needs some instruction on procedure. Looks like a start over to me.

Some installers only care about what the end result looks like...not necessarily how well it will last or perform. FWIW, a properly built shower should not leak water prior to when the tile is installed...neither the tile nor the grout are considered the waterproofing...they are the decorative, wear surface.

He keeps telling me the liner keeps the curb waterproof and the pan. Nothing else is needed. I haven't paid him because it looks bad. The marble on top hangs over an inch too.

Not if you poke holes in it to anchor the cement board! Plumbing code calls for NO penetrations through the liner below 2" ABOVE the top of the curb. The only place you can safely put some is on the outside, preferably down low. On the walls, that also means that the bottom of it is not anchored, at least with screws. Depending on the class of CBU you use, IF it is the one that can be embedded in the setting bed, that is how you anchor the bottom edges...by packing the mud up against it.

Thinset does NOT stick to the liner, so what's holding the marble cap in place? Industry standards also call for at least 95% of the horizontal surface and 100% of the edges to be covered in thinset.
