That looks terrible, I would ask for it to be replaced.

This is unacceptable.

I would never be ok with that!!!

How could someone install this and leave? Have you asked the installer what happened. Would be interesting to hear the excuse. Regardless, it's not acceptable and I would have it removed or remove their pay and hire a pro. If redo is refused I would report to BBB, write a review on company's website, if there is one. Also, if you paid with a CC, they offer some recourse.

We bought the house as new construction thru a community. I did not hire marble company on my own.

Absolutely unacceptable!

Are you sure it's cracks and not natural veins?

They look like natural veins to me. This is not a look for everyone. If you don't like it, definitely have it replaced when you can.

Sorry...just saw your other photos. Yikes!!! Yes..get that replaced.

Raise cane with the community sales rep, this is a deal breaker.

Oh Poor YOU!!!! Is the surface smooth? Check the under side to see and feel if it is smooth. You choose beautiful stone but it looks as if the installers dropped the all of them and then made a sorry attempt at trying to salvage it. I hope you don't have to live with this mess.

That is the natural veins in that stone..Ive seen these slabs before at the stone yard. they should have shown you the slabs for approval before they fabricated it.

If you don't like this - complain and have it replaced. I personally would have rejected this. At a minimum, the builder should have shown this to you prior to installation.
