Well, that sucks! I am sorry for you! I have to say at first I didn't know what you were talking about, b/c by the grace of nature you have imperfections in stone, and the veining does help the cause. But when I scrolled down I noticed OH NICE ..a hammer hit that right there! NOT COOL. I would first address that it is damaged, and see what they say. I hope they are willing to work with you, split the cost, or else. I mean let's face it! Don't pay them another cent until it is resolved to your liking. I know you are near the tail end, so hang in there.

Use that spot to mount the bracket for the hand shower. Or to add a soap dish. Or something.

Are you 100% positive there was no large flaw in the stone at selection point? Did you closely inspect every inch and sign off on it at selection point? . It is not uncommon to find divots in a slab....and that is not a good fill job and it's a big divot.

That does not look like damage to me. If that's a repair, those guys are really, really, good. They've nailed the colors and striations in the stone perfectly although I can't see the finish in the pictures.

If it a repaired gouge, ask them how deep it is. It could be ground out and since it's a vertical application and probably doesn't get direct sunlight, any distortion would be minimized if noticeable at all.

@Joseph Corlett, LLC are you looking at the same spot we are? where there's a big black splotch in the middle of a white expanse? that second photo is the repair, which is halfway down from the showerhead in the second photo. not at all subtle!!

if you can't cover it cleverly, I think it has to go.

"@Joseph Corlett, LLC are you looking at the same spot we are?"

I think so.

"Where there's a big black splotch in the middle of a white expanse?"

Yes. A black splotch in the middle of a white expanse is completely consistent with natural stone, however, on second look, it seems remarkably coincidental that this splotch lines up perfectly with the shower head above and is just the right size to be a patch of a mis-drilled hole. If I were there, I'd start looking for a mathematical relationship with a tape measure. For instance, is the distance from the proper shower hole to the floor the same as the distance from the patch to the ceiling? If so, someone measured from the wrong end. We could be seeing the results of dyslexia; someone read a tape as "69" instead of "96".

If this is indeed damage they did - they should pay to replace the slab. (Hope you can get the same lot to match!) This being the shower, I wouldn't settle for repair that may in time allow water to seep through.

Maria, you need to come up with more details. Unless you very specifically state that somebody damaged your slab you will find people here somehow blaming this on you and demanding you accept this.

From the look of the ragged edges it feels more like a grinder gouge..maybe started opening the lower square hole too high up? . Would bet my bottom dollar not natural, grain seems to large for too short a length and in the wrong axis. Agree with Sophia- get creative and cover it up and then ask for explanation/compensation. Another thought is if I or one of my subs were doing the install would have pointed out to the client right away..so as not to get blamed for it.

Maria - so sorry this happened. Did you get it resolved?
