You have lippage. To fix you need to tear out, rewaterproof and retile. Do you have a contract?

No it is not supposed to look like that, and you shouldnt accept it. It needs to be torn out and all started from scratch on a nice level surface. I am wondering what is underneath that tile. Is it waterproofed and done properly, or are you going to be tearing it out because of improper installation and resulting mold by this time next year. Please google, for correct waterproofing procedures for a shower, and then see if yours is done the way it should have been.

And no the tile is not flat. Look at the circled area.

Also what did they use for waterproofing the shower?

This often happens with long tile, and the recommendation is 1/3 offset rather than brick joint, or stacked like your lower pictures.

Put that tile back to back, and you’ll see the gaps from it being bowed. Because it is. If you had done the stacked pattern instead of the offset, you would never have seen how bowed the tile is. And the grout lines are too small to help disguise that as well. No way do you want gray grout with that tile. It will only show you other things you haven’t noticed yet.

Redoing this compromises the waterproofing. How does your GC plan to handle that? Or, did he not use waterproofing?

Plan B. Place the tiles face to face and they will rock. They are not flat just as Tundra first stated. A professional installer would have inspected them out of the box before install and rejected them and informed you of options. I can't comprehend continuing the installation after seeing the result of the first couple of courses. That speaks to the quality of the installer. You should certainly be skeptical about the waterproofing and inquire to how that was done. Any attempt at repair will risk damage to the waterproofing if there is any.

Here's the deal, if homeowners would understand this one thing, it would alleviate many of the problems that occur with tile installation, and other things as well. Multiple people are involved in the decision regarding the tile selection and NO ONE talks to the actual tile contractor before the final selection is made. Involve your craftsmen/women! If you hire a GC, one of the most important considerations should be who their subs are (qualifications) and how they involve them in the design and selection process. That model should be in place for all remodeling and construction projects. In this case you received your information from the tile supplier and the GC/project manager, but it appears that the actual installer was never involved. You should be meeting with and involving them before you even make a selection on tile as they should be able to advise on expectations, "great look but here is what this requires... "(which may also be helpful for the GC as he/she will need to make sure other preparatory work, or pay the tile contractor to do it (substrate, etc.) is in order to achieve the desired tile installation. As an old timer in the field, I recall many years ago getting drawings from a designer, a selection sheet from a tile distributor, and a schedule from a GC. I would get to the job and say "OK, so here's what you can do and here's what you can expect. Here's how we can alter this based on this or that consideration". And then we would have to decide how to proceed from there. Major mistake and one of the biggest problems facing the industry today. IF you involve the tile contractor early on and are equipped to ask the pertinent questions, you will know a great deal before the actual selection and installation occurs. What you also might learn, is that that sub contractor is not up to the job. Better before than after. Sorry for the rave but we are passionate about the tile trade and the impact on consumers like you. You did not select the wrong tile. It was an inadequate installation. It did have challenges to plan for by a real pro. Final note: Happy to hear that you have a stand up GC willing to make it right (and note the comment from Creative about the damage to the water-proofing if tile is removed). Stuff happens but if in the end they deliver, than all is well. Good luck with your project.

Did you look at any photos of the previous work ? thats a terrible job, you will have some slight uneven tiles on any tile job on the wall but that is absolutley terrible , no integritey or experience or both

Heres a job im finishing up , there is no perfect tile job but it should not look like yours under any circumstance
