View of the sloping as well.

In the picture with the Ace bucket in it, are we looking at the finished shower floor, carving up on the near end, above the room floor, and appearing to be wavy off in the distance? Or is it the wavy tile just making me think the shower floor has rolling hills in it?

I’m with Nancy. Unless there’s some sort of distortion going on in the photo, that is a shockingly bad tile install. I’m sorry to say that but it’s true, and the aesthetics are not the biggest problem - if the picture is accurate you will have serious problems with the shower unless it is redone.

The picture is not distorted. Those are the pictures taken by the GC asking for final payment.

Have you seen it in person? Have you asked the GC about it, and what did he say?

I'm sorry to say it doesn't seem as if this GC was the right person for this job. How many curbless showers have they done? Did they share more pictures of the work in progress?

I do have to agree, this is shockingly bad. Is this being done somewhere that you are not able to see it in person?

I’m out of town for work. But my husband confirms that this is what it looks like. I mentioned that the Cg sent these pictures as if he’s proud of them.

Ask the contractor how the shower was built to TCNA standards.

I've never seen tile "curve" like that before. Is that really tile on the shower floor? What type of waterproofing system did the GC use? You need more info about the whole job. Also, if you share the shower and room dimensions, a Pro can give you an idea of the grade required for zero entry. From my preliminary research for our ensuite, I know it's not a simple installation and can't be done in every space.

Just when you think you have seen it all, all comes this hot mess...........................

Megan it’s unfortunately a really serious mess. I have to say I’ve been reading Houzz forums for years and have seen some really bad tile installs, and this is one of the worst, if not THE worst, I’ve ever seen. There’s just no way that what’s under that tile could be correctly done. It has to be completely torn out and redone from scratch by someone competent. It is true that the type of entry you want is more difficult than a curbed entry, and it will and should cost more because of the time and skill it requires. But this person is so incompetent that I wouldn’t let them redo the work even if you switch to a curbed entry. When it is being torn out, take the best pictures you can of what’s underneath, layer by layer. Also take excellent pictures and video before it’s taken out, and if any of the materials the installer used are still in your house, take photos of those as well. Get any markings or labels that identify the materials into the photos. All of this will help you prove the installer did not follow the TCNA standards Dragonfly showed above, so you can hopefully recoup anything you’ve paid, and get out of paying the rest. I would also find a really good tile installer (I’m sure you thought the first one was that) and see if you can pay an hourly rate for them to come look at this before taking it out. Ideally get something from them in writing about the quality and correctness of the work. I’m sorry you have to deal with this.

He didn’t get the tile pattern right either. If you want to keep adding up reasons that this needs to be torn out and redone. This cut your foot “speed bump” shower is one of the worst things we’ve ever seen on here. What was the quote for the shower? The standard 15K-20K area?

I’m no pro, but this does look like it needs to be torn out and redone. I’d suggest you rethink the tile selections as well, perhaps. I don’t think the current tile works well, aesthetically, and it seems like it will be a nightmare to clean that wall tile. This board is a great place to gather ideas.
Sorry this has happened to you.

Another thought - there’s absolutely no way that is up to code. So presuming your area requires inspections that should stop this in its tracks and give you reason to not pay. If no inspection is scheduled I’d call the building inspector for your area to come take a look at it.
