ᐅ Ikea Metod: How can I securely install countertops on sloped walls?

For a wall inclination of about 5 degrees and a masonry wall, I would recommend the following:
- Build a battens substructure using treated construction timber, which you attach directly to the wall with spacer washers and heavy-duty anchors. Adjust the battens horizontally using a spirit level.
- Use rubber pads at the contact points between the countertop and the battens to minimize tension later on.
- The countertop should be screwed onto the battens, not directly to the wall.
- The Metod cabinets that support the countertop should be aligned to create a flush connection. Pay special attention to the connector profiles between the cabinets to prevent warping of the countertop.
- For Ikea Metod, it is helpful to use the manufacturer’s recommended brackets for countertops, combined with your own adjustments for the wall inclination.
If you like, I can provide more precise information on suitable screw types and fastening methods.

Stay flexible: Use adjustable brackets to adapt the countertop to the wall angle. Additionally, spacer material between the wall and the countertop often helps. Pay attention to the rigidity of the base cabinets.

I can fully agree with the recommendation to use a batten substructure, but here’s a practical tip: If you don’t feel like measuring, adjusting, and celebrating with a spirit level, use an adjustable bracket that can be fixed with a screw. This way, you can position the countertop while the cabinets are already installed—even if the floor is uneven. It saves a lot of hassle and annoying readjustments. With Ikea Metod, this is quite an elegant solution because the brackets are often nicely “hidden” behind the countertop.
