Gap between bathroom cabinet and wall

We have tiled the bathroom only up to a height of about 1.35m, so the bathroom cabinets now stand about 1.2cm away from the wall in the area above the tiles. Do you have any idea how to best "fill" this gap? Are there possibly moldings or do you have other ideas?

Put the patch strip on. With mounting adhesive. Check at the hardware store or ask your construction carpenter what’s possible. Our building materials supplier, for example, has thin PVC sheets in various colors, white, silver, gray, etc. One costs 11.99. Then have it cut, two strips in the right width. And stick them on there. Apply acrylic seams. Done. Karsten
