I'm no pro, so I don't know if it is an install gone wrong or not. But to me it looks kind of like it is supposed to be like that. The cement? around it has all sorts of bubbles, imperfections, ganked spots. The brick behind it is kind of rough looking. The flagstone and peagravel floor. So if the slabs were too perfect, it would almost be out of sync with the rest of it.

Oh man that’s tough, they ground the finish off the face in multiple places. How did you find these people?

@ci_lantro This is all brand new build. no existing structure. just dirty since still under consttuction. laminam and porcelain slabs are used often outdoors and look great and hold up nicely. Im more looking for an actual fabricator, stone dealer, or designer who has experiemce with this material that can give an opinion on the outcome of this job specifically.

The printing on sintered slabs is microscopically thin, but they've got to ease the mitered edge. The more they ease it, the more of the printing is eroded. That looks like typical work to me.

Part and parcel of choosing a material with a printed face, rather than solid all the way through. You will always see the cuts, and the eases, etc. Because it's not solid pattern all the way through like a colorbody porcelain, natural stone, or quartz.

Just as an uninformed consumer, never used this stuff and never will, I think it looks . . . not good. Unless one is trying for an old, worn, distressed look.

I am sorry, but it is not a good job! Who ever says it is normal, has very low standards for good quality job! Professional porcelain slab manufacturing companies use water cutting machines for this material! So they can get as perfect 45 degree edge as possible to make mitered adge!

This sink is full of mitered edges and made from Neolith porcelain! It is difficult material to work with, so you have to be professional! And professional manufacturers would connect big part of mitered edges at their fabrication location, not at the spot! Looks like they connected all those edges on the spot on the installation day! I would try to complain, specifically they have damaged the surface of the material even before installing I guess!

That doesn't look any better. At all. It has the big old white line of the underneath material showing too. Because it has to. You can’t leave a razor sharp angle there to cut someone.

It can be done much better! It is like caulking! One will make big, wide line, few others will make perfect small line! The same with joints of mitered edge! If you put too much glue or what ever product between 2 pieces already can create problem! On top of that, it is recommended to use plywood under porcelain slabs to give extra support for slab and mitered edge! Unfortunately the person who have manufactured the countertop has damage material even on top of the surface! You want to tell me that this looks good? This is totally botched job! And people should get their money back for material and that job!
I have mitered edge all around in my house, with marble, with porcelain, with quartz! And people who don’t know how to do seamless edge, will botch even marble mitered edges!

Porcelain is a different animal, and you need to get a fabricator with a lot of experience with porcelain and look at jobs they did a few years ago for cracking etc. Houzz has lots of complaints about porcelain countertops so I knew I needed to be careful. We just installed 13 slabs of Laminam in our master bathroom using a contractor we found on Houzz. Sorry to say, but it looks much better than yours.
