If you get Conestoga, you can get any size you want and even design your own door style. I had one door that had a flaw in the paint and they replaced quickly.

I use Ikea for a decent price point and I have done many kitchens where they look custom with good planning.

This is a before and after all Ikea and the red one all Ikea

It is important to understand the term stock. Stock generally means you walk into the store and come out with the cabinets in hand the same day. These would generally be the stuff on the shelf at Home Depot, etc. These will be inexpensive, lower quality hardware, and a very limited warranty.

I think what you are probably really calling stock are what is usually referred to as semi-custom. You order these through your designer and they are not built until you order them. They are not kept on the shelf to be picked and shipped even. The amount you can modify them from 3” increments varies with the cabinet line as does the amount of sizes offered. Kraftmaid cabinets are a well known line of semi-custom cabinetry.

You can walk out of Ikea with your whole kitchen actually

How durable are ikea cabinets? 3 of these units are rentals & 2 are full time apartments. All ocean front so moisture is an issue too.

It really depends on what you want, and what challenges your particular kitchen presents.

What style of kitchen are you looking for? Drawers? Inset, overlay, or frameless? Do you have odd shapes/places? Are there specific elements you want to incorporate?

Ikea might be a good choice for rentals. I've even known some people to use Ikea boxes and custom doors.

IKEA is considered stock cabinetry. Stock cabinetry can be challenging to design with, especially in a small space, given their limitations in box sizes. But if you can get the layout to work, I think it's a smart value for a rental.

Agree with Kristin Petro. In my market IKEA kitchens are received very well in both rentals and sales. Naturally you need to put some thought into the kitchen plan so its functional, but those kitchens are a very good solution for rentals and full time residents.

One advantage of IKEA kitchens is you can go basic with the boxes and doors and not spend lots of interior fittings. Then if tenants want to customize the space for their needs, they can go to IKEA and find organizers to match. If you have a tall cabinet and put in shelves a foot apart, they can go buy a couple more and rearrange the spacing themselves.

Depends on the cabinet company - as mentioned by @mainenell above, there are quite a number of companies that offer semi-custom, and you can get cabinetry in the exact sizes you want. In addition, many custom shops do not make frameless cabinets, so if you want frameless (I do), you should avoid custom. It would help if you were more specific about what you are looking for - style, budget, specific features you want, size of kitchen.

I have used Ikea cabinets in my design biz for over 20 Yrs one of my clients had 5 kids who have all now grown and left home and that kitchen still looks great . I have done Ikea in Miami Beach at the lake in BC. all over the place with no issues IMO Ikea has some of the best hardware on the market many finishes to choose from and an awesome price point.

I would absolutely do IKEA for a rental. In addition to the advantages others have discussed, if someone damages a door or drawer front, it's easy to replace.

Rentals are on a depreciation schedule. It’s not uncommon for them to be gut renovated every 7 years. No one would expect 50K worth of custom cabinets in a rental. Not even a high end rental. A high end rental would expect a much better overall design though, even using semi custom cabinets. A better functioning and better looking rental attracts better tenants and a higher rate.
