ᐅ Ikea Metod: How do I install kitchen cabinets on uneven walls?

Hello everyone,

I plan to install an IKEA Metod kitchen in an older house with walls that are unfortunately not straight. Specifically, two walls in the kitchen area are slightly uneven, which becomes noticeable when adjusting the cabinet carcasses and especially when cutting the countertop. My question is directed to experienced DIYers and kitchen installers: How do you approach the assembly and installation of Metod kitchen units when the walls are not square or even?

I am particularly interested in
- how you fit the kitchen run to the wall while still achieving a straight appearance,
- whether you use any special techniques or tools to compensate for uneven surfaces,
- and how you adjust the doors and drawers so they close perfectly despite the crooked walls.

I look forward to your tried-and-tested tips and methods to help me install the kitchen securely and attractively. Thanks in advance!

When dealing with uneven walls, I always use a mounting strip that I previously checked with a spirit level. I attach this strip straight to the wall and then mount the Metod cabinets onto it. This way, I hide wall irregularities and create a straight line.

Adjustable furniture feet and flexible fastenings help align everything stably.

To address the issue of uneven walls with the IKEA Metod system in more detail, here are some specific tips:

When measuring, be sure to take multiple measurement points on the walls: height, depth, and angle. A digital angle finder or a spirit level with an inclinometer function is useful for this. Uneven walls usually mean the wall is neither perpendicular to the floor line nor straight. This is important for ordering and fitting.

For installation, I recommend:
- Use warped mounting strips or compensate with wooden battens to create a flat mounting surface.
- Align and level the Metod carcasses precisely using their adjustable feet.
- For the countertop, it may be necessary to file or sand the front edge of the lower cabinets at the top level before placing the countertop.
- For the doors, readjusting the hinges is advisable, as those in the Metod systems tend to be very flexible.

Finally, if the wall is very uneven, you might consider using intermediate layers of plywood or chipboard so that the kitchen appears visually straight—even if this means the cabinets are slightly offset.

I’m curious, how far out of plumb are your walls exactly? A few degrees or more?

Good question. I measured with a laser level and spirit level, and the deviation angle of the wall is between 3 and 5 degrees from vertical, so noticeably out of plumb. The other wall is only minimal, about 1 degree.

That sounds reasonable to me, especially with 3-5 degrees out of plumb, a mounting batten for leveling definitely makes sense.

I want to avoid having the countertop installed crooked or doors misaligned, which could lead to drawers sticking over time.

Would you recommend cutting the carcasses for short walls at an angle accordingly, or rather use filler strips and battens?

I have encountered similar situations often. My advice:

- Keep cabinets straight in general; avoid cutting them at an angle to match the wall. This preserves the structural stability of the carcasses.
- For uneven walls or non-right angles, it is better to use filler pieces made of wood or MDF, which you can cut precisely to the millimeter.
- Place these filler pieces between the wall and the cabinet to close the gap neatly.
- Finish by covering with suitable trim molding—this creates a clean and professional appearance.

Adjustable feet also help you keep everything aligned despite uneven walls.

One of the great things about Metod is that the hinges and drawers are highly adjustable, so small wall irregularities won’t affect the door function.
