Will there be trim around the cabinets? Are the doors overlay? My guess is that once the doors are put on, you won't see that gaps.

Definitely ask your cabinet installer. Just say” I was wondering how/if/will…..”. Maybe it’s the depth of the doors or trim space. Good to check before it goes further just incase.

The cabinets are built straight but your walls might not have been perfectly straight, and there had to be space to push the unit in. Let the cabinet maker finish, you won't see any gaps. They make magic happen :)

The custom part of cabinetry is what you get on the interior of the cabinet. The cabinet needs room to be placed within the opening so it will not be flush. The trim will cover the gaps, which allow the cabinet doors to open without banging against the walls causing damage to your cabinet.

Saying custom does not indicate quality, or better than, but simply made or done to order for a particular customer.

Don't assume your vision is shared with whoever is doing the work. Ask questions, ask for drawings with sufficient details (ask questions about the drawings if you are unsure) so you are confidant you will receive what you expect.

When you are faced with a problem or question like this, first go directly to the person responsible and communicate with them. Explain your concerns, ask questions, stand your ground. You don't need backup from a bunch of strangers on the internet.

No one here knows anything about your project or why things were done the way they are, but your contractor does and is the best person to answer your questions.

Thanks for the feedback, All! Since we haven’t done a remodel before, I just wanted to make sure we weren’t dealing with unrealistic expectations (of cabinets literally being built-into the wall😜). Yes, there will be trim and doors, and you’ve all reassured me that they weren’t just cutting corners. ☺️
