Are you sure your counter top is completely level?

You either live with it, or dig up the wall. The support is into the wall.

You tiled AFTER the shelves, were installed, did you not? That's a lot of shine: ) Hard to see what is going on in your pic

No @JAN MOYER, we drilled into the tile to hang the shelves.

Then he probably used a GROUT line. And that tile isn't perfectly level: )

You either live with it, or figure out exactly what isn't level. What's on the left, a bracket of sorts?

Personally, the tile isn't a great look, too metallic?

Add your accessories and then decide if it needs to be redone.

No @JAN MOYER the shelves are uneven to the grout line.

Only you can decide how much it bothers you. Fact is it isn't level ( 3/8) by nearly a half inch....over whatever total span. I can see a 16 th or less when hanging a picture on a wall.

You see what YOU see.

The tile is stunning @JAN MOYER. its mirrored. what a rude comment. don’t know how you’re a pro. you seem pretty clueless.

I think once you accessorize, it won’t be as noticeable, especially if you use different heights. If it still bothers you, assume it always will.

I noticed they were a little crooked. Measured to see they’re 3/8ths of an inch off.

Show us what a level says, not what a measuring tape says. A long level, at least 36" long, not a torpedo level.

A good tile setter can cheat 3/8" out of level/ plumb so you can't necessarily rely on grout lines to tell a story.

Fix it. If you put something on those shelves that is round, it will just roll.

It actually doesn’t roll, @Jeanie Miller! we tested it

I measured each side from the top of the countertop. Anyway, I have a good eye and definitely notice, which is why I asked! @ci_lantro

It would bother me if I noticed it constantly, but I’d also have to be practical about whether fixing it would tear things up.

I definitely would try various shelf decor layouts first, seeing how types of asymmetry and “ weight” or size of objects helps fool the eye.

If just simple shelf styling isn’t enough, another option is to use an object or two that hangs over the edge , disrupting the linearity of the shelf edge. Things I can think of are a small trailing low- light houseplant like a pothos ( just barely trailing, not a monster) , though plants might not mix with the food and drink use. Or, a stack of linen napkins “ artfully “ arranged so a few corners drape over the edge. A third kind of thing is a bracket from the edge, like some small iron artwork, or a great photo ( no cutesy writing signs though). Again you would need to see what is the balance between objects & arrangements that might help the shelf angle problem vs don’t go with the whole inspo look or functionality.

What lighting are you using in the nook?

That’s great advice, thank you @marmiegard_z7b. We actually don’t have lighting. It’s just a little nook in our living room. I did talk to the guy who did the install and he said he’s certain the holes are level and that it might be a bracket issue. He’s coming by Monday to check it out. I’m such a perfectionist that I’d like to fix it, but like you said, it might not be worth tearing out and replacing tiles to try again.

Fingers crossed the simple fix works, but if not I will definitely experiment with some of your wonderful suggestions!

I'm sure the installer will have a level. Have him check the countertop too while he is there. I'm a perfectionist too but I'd also be concerned with damaging the tiles if you try to redo it, especially if it isn't that noticeable. You'll see what he says on Monday.

If it's not adjustable, I would try styling it as others have suggested to see if you can minimize the effect. It is difficult to see in the pics because of the reflections, but it's not at all noticeable to me. If it's going to be a bar set up, maybe there is a way to add a holder to a section where the wine glasses hang upside down. It might hide the grout lines that probably are what make you notice the disparity.

In this instance, I think the should you fix it is determined by how can it be fixed without then requiring other things to need fixing. Did I read the supports are drilled into the tile? If new holes are drilled will the old be visible? Will 2 holes close together cause a tile to crack? Is this an imperfection that you can or can’t live with or an imperfection that makes it unusable?

Accessories may make it worse, showing the slope.. or they could hide it. I can see that fixing it would be tough to do without damaging the tile. You should gget the guy back to give you suggestions. He is the one who messed up. Maybe thicker shelves would hide the drill holes? You could leave it, it’s not that bad..but I would always know it was crooked.
It is a very pretty selection by the way. Well done.

If you haven't already, I would try styling it with what you intend to put on it to see if it helps or makes it worse. That may help with the decision.

It's good that your installer is coming back to have a look. Checking the level of the shelves is first. If they are level then the counters might not be. All the tile is installed so trying to fix could be an issue. I do agree with others, once you decorate, you may not notice it. But only you can decide base on how sensitive you are to the difference.

Good luck - hope it works out

Thank you @Suzi Hanks! exactly. I’ll always know it’s crooked but might just be one of those things where I have to accept. The installer is coming back Monday and mentioned it might be a bracket issue, so fingers crossed he can help.

the shelves are custom and were really expensive so replacing them isn’t an option!

thank you for the kind words about the selection. i think it’s quite stunning, and not at all glaring in person. it’s a beautiful antiqued mirror tile and picks up light in photos because it’s mirrored.

i can’t believe the audacity of some ”experts,” to say they’re arbiters of taste and denigrate someone’s choices when they weren’t asked. not very professional!

mirrored bar areas are not exactly a revolutionary or unusual choice!

I agree; it's the height of rudeness to denigrate choices that have been made, that are obviously not changeable without great expense and likely loved by the poster. Especially rude when it's not regarding the question asked. So many posters disappear after comments like that, so kudos to you for sticking around!

A measuring tape is useless without having a known, proven level surface to measure from. If round things aren't rolling off of the shelves, that suggests that your reference point isn't level. The floor could be out of level (not an unusual situation) and the cabinets weren't shimmed to level and the counter top installer could have just slapped the counter on top of the cabinets without shimming the top.

Even if I had a know level reference point, I wouldn't rely just on measurements to install shelves. A level is an indispensable tool that should be in every homeowners basic tool kit.
