Plumber here. The shower liner looks like it’s not installed correctly.

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.

You would put the waterproof membrane on top of the mortar bed after that is poured, if you were worried about the integrity of the shower pan, not directly on the shower pan.

Makes sense. That is the piece I was missing.

I wouldn't be worried about the curb as much as how low the screws are inside the pan, as the top of the curb isn't going to hold water like the pan will. The pan needs to be watertight to 2" above the curb by code where I am. If they have screws below that, the liner should be replaced and whoever put the board up should pay for it.

Just to confirm: the concrete under the liner isn't flat, right?

Your cement board is in the wet. It's not supposed to be in the wet.

Lucky for you, you can still "fix" it by either using Kerdi or Red Guard over your dry pack.

Not a plumber but the liner usually goes on the inside of the walls so the bottom of the wall isn't sitting in water.

No, shower pan membranes should go behind the cement board. The cement board should just stop above the finished floor height.

Concrete has been poured, this isn't "sitting in water" at any point.

The liner should come up 10" from the floor depending on local requirements. Not a plumber.

Screws are high enough. It's fine just tile it. Waters not going behind the grouted and caulked tile.

Yep, water has never gotten behind tiles before.....

Too much of a generalization. The pictured system works. With the floor as poured concrete and the cement board i'm assuming thinset will be the adhesive and that will be absolutely fine

You don't need an inspection if you don't get the permit, right? /s

Legally it’s supposed to be permitted and inspected. At least in my jurisdiction. So things don’t leak.

I know. It drives me nuts when I see people DIY without. I get that it's an extra cost and all, but as I've said before: Fire bad, mold bad, electric shock bad. I fully support learning as you DIY, but there are some things you just don't want to wing it.

true, but if you sell the house and it gets inspected then, you can be sure they won't let you sell the house.

I wonder how many folks who waved inspections during the lovely house buying spree are going to be screwed on that one when/if it comes time to sell because of the lovely DIY flippers.

Home inspections are a scam anyway. The stuff these guys pick out is usually blatantly obvious. The things they should be looking at , they can’t, unless the seller is willing to let them to open walls. People are good at hiding things.

Depends on the state. Grew up in MA, bought and sold several houses there. The inspectors went DEEP, removed covers, actually investigated things, and were allowed to do so. In Texas, the pre MLS reports and buyer inspections are laughably bad. The shit I found immediately after closing that absolutely would have been noted by my inspector in MA were missed by two inspectors in Texas. Turns out, it's because they aren't allowed to remove things like switch and outlet covers. All they can do is say "Switch doesn't seem to do anything, contact electrician" when simply removing the cover will reveal that the asshats who built the house used the quick wire slots in the back of the switches and outlets and they had cracked over time leaving the wire loose in the box. $1, 2 minute fix for anyone with a brain.

There's no way to inspect the placement of the shower liner...

But when they look at the plans and see bathroom where it once said walk in closet, they can and will say, I need to see the pipes…. Even if it means cutting a finished wall.
