Can you take a picture from further back? Usually removing a cabinet from under stone is not advised.

@Rachel SimanskiI've updated the photo. It's a door at the left, and sink at the right

Yes. Support the top if you have to. We occasionally do this.

@Creative Design CabinetryThat's good news, but how? The countertop is glued to the cabinets. How to remove the cabinets from under without damaging the cabinets?

Depending on how it is attached, you may or may not damage the cabinets. repair if needed.

It required the filler. Leave well enough alone. It functions.

@Creative Design CabinetryThe cabinets were glued to the countertop using marble glue and curing agent. So there is not a safe way to deattach the countertop?

@User It doesn't require the filler. I can remove the filler and add the 3" space to the 18" cabinet to make room to install an 21" cabinet. If there is no safe way to remove it, then I'll leave it alone. It functions ok, it just doesn't look quite right

Are those doors or drawers? If doors you probably need the swing room...

Yes, take your time and like Creative said you might need to support the top

@David Hanson

I think my contractor can support the top, but the cabinets are attached to stone top with glue. How do remove or loose the glue?

Odds are that the wood will be damaged. They realistically could not be returned anyway with the tops having been glued previously, if that is where you are looking.

I would try cutting the glue/ sealant with a multi tool , might take a while depending on if there is corner bracing in the cabinet

@millworkman

I'm not looking to return them. I plan to use the 18" for the island

@karine dav

There is no corner bracing. Cutting the glue with a multi tool sounds possible. But how long would that take? My contractor said he would do it if there is a way. But if it takes too long, I wouldn't feel right to ask him.

All cabinet runs beginning or ending against a wall require fillers. Require.

@User

I have recessed cabinets. Why would it requires a filler?

You are looking for a fix to gain a few inches, but you chose a cabinet style that reduces available storage space.

Symmetry is way overrated!

My issue with what I see of the kitchen, if I was looking to buy the house, is that you didn't do drawers for your lowers.

It's fine. Finish the space with toekick and hardware and then add your countertop appliances and decor. You are looking at an unfinished space and as soon as you start living with your new kitchen, you will forget about that nonissue

I would leave it alone. Post a picture of the whole space. I see a door knob on the left by your countertop...even more of a reason to leave room between the wall and the cabinet door.

The whole thing was designed badly. Inset should have used an scribable extended stile of at least 1 3/4” as a minimum, to have 1/4” scribed to the wall. Then that would have echoed the butted 1 1/2” butted stiles of the other cabinets.

Better yet, the whole thing should have been combined cabinets, and not separate individual cabinets with seams in between. Most cabinet lines will combine up to 96” in length.

Whomever designed this was used to designing with stock RTA cabinets, and had no clue about inset.

@lucky998877

Added a photo of the whole kitchen. It's a mess as I'm trying to move stuff in and my contractor cann't open the sauce drawer! Fortunately that side of the countertop hasn't been glued to the cabinets yet.

@User

I totally agree that it was designed badly.

@chispa

I have plenty of drawsers as the island has 6X30" ones.

Another issue is that the cabinet nextby the refrig is 18", and there is a 3" filler there too! I'm thinking to replace them with a 21" cabinet and put the 18" one in the middle of the island between the drawers. Another plan is to put a mini frig in the middle. The third plan is to leave 11.5" space at each side. The island top is 36"x83".

@Lyndee Lee

I also wonder if I care too much about symetry. Hardware is another issue. I ordered it from the same store with cabinets but now they're saying it's out! That's why I'm having towels all over the drawers to keep them not shut:-(

Why are they gluing the top to the cabinets? What are they using for "glue"?

@millworkman

I meant the overlay on top of the cabinet is glued to the stone, using marble glue and curing agent

Cabinet store just called me that there is a way to remove the cabinet from under without damage. They said to remove the drawer first, then support the countertop. The cabinet should be easily removed. However, after the call I realize that the cabinet is nailed to the overlay. so the top has to be raised over 1 and 1/4". Is that possible?

Honestly you won’t notice the different sizes. Leave well enough alone. Don’t worry about what can’t (or shouldn’t) be changed. Focus on the positive and enjoy your new kitchen !
