To succeed with A professional looking tile installation, it is paramount to FIRST make the walls Plumb, square and In-plane. This happens very early on, it should have been spelled out in the detailed scope of your Quote and explained to you when you compared price estimates.

Agreed. Is it fixable to do it section by section or do we need to remove all tile and start over with a level surface?
Thank you !!

It is all new construction which is why we are so shocked that it is so warped :(

No, it’s on the first floor. There was Drywall, backer board , hydra ban, then what you see is the layers of mortar used to install the tile. Is it too thick? They want to just fix small areas, and my builder is accepting what they say as truth....I need an expert opinion to let my Builder know that using them again for this patchwork repair may not be a good idea.

Here are a couple from the process and one more of how the schluter was too wide so they opted to angle out the wall instead of finding one that fit properly :(
My concern is they use up my remaining boxes of leftovers to fix it and then when its all said and done and still doesn’t look good I don’t even have the boxes of leftover tiles and they run from their obligation saying they think it looks just fine.
It’s been a long tiring road with this house :((

Yes, curbless...was suppose to be a roll in and Builder ended up using no shrink grout in there instead of continuing the concrete due to not enough depth for Concrete pour there? Not sure about a flood test or inspection. Haven’t heard of those. Was informed they used hydra ban to coat the walls and trusted they did I suppose

The lame leading the blind flustercluck yet again. Even if everything behind the tile was perfect, and it isn’t, you are still dealing with wonky handmade varying thickness and squareness tile with too small grout lines to get a perfectly flat wall.

I’ve seen this encaustic cement tile used everywhere lately and the craftsmanship is beautiful. I’ve been sure to keep an eye out for it the last couple of years to notice how it has been used. Always the smallest of grout lines. Never have I seen the waves I have here

Sorry but I don't see any hydro an on the cement board and encaustic tile needs a 1/8" grout line. I know that because I put them in my friends entry hall

I'm so sorry you're going through this! I've been through my share of nightmare projects, too. New houses are NOT immune from warped wood, out of plumb/out of square construction, or any of the other problems generally associated with older homes.

Modern wood used for studs and joists (especially that found in big box stores) is often still "wet", or contains moister/sap that will react to different temperatures and humidities. The cut of the wood (cut to get the maximum amount of lumber out of a tree) will often lend itself to warping, cupping and twisting, putting everything down the line out of whack, including your tile.

I'm afraid you won't be happy with the results of them patching together the tiles that were left. If it were my project, I would have them take it back to the studs and true everything up the right way before tiling. I'd also have them re-tile the whole thing on their dime; but that all depends on what was in the contract and how good your GC is. Good luck and let us know how it all goes!

So the Builder is refusing to redoing it and choosing to just redo the corners where the waves all met and were most noticeable. Any thoughts on this? I expressed my worry about a vapor barrier with such an uneven surface but I don’t really know what is right or wrong. Any opinions are greatly appreciated.
I did have two other professionals come in and say it was a complete redo but nobody wants to get in the middle of this. The entire house is new construction.

"I did have two other professionals come in and say it was a complete redo but nobody wants to get in the middle of this."

Well there is your answer. You need to find out if there is another tile professional or inspector that you can pay to get a written report on the shower, but if two others (who have seen it live and in person) plus everyone om here are all telling you its a conmplete do over....................

I hear you...but the Builder is refusing to hear it and the rest of the house isn’t complete and nobody is willing to refund us for the tile or installation fee. Builder is siding with the sub he hired.

Is the builder licensed in the state you live in? I would pay for an independent report by a tile professional, someone recommended by TCNA, provide this report to the builder and the builder license issuance agency in your jurisdiction. I would also start looking at my contract with the builder and speaking to a lawyer about the proper way to provide the builder information so you have legal recourse for all the other issues you will find in this house. This shower does not appear to have any waterproofing installed.

Good luck!

I'm sorry but from what I can see, there is no waterproofing on the shower.

That is just a symptom of other things in the build that you have not noticed or can’t see. Time to read the contract with your lawyer.

Time to get a lawyer involved. Your tile folks are hacks and your builder is untrustworthy. That is a terrible job from the start - they did literally everything wrong.
