Take a 140cm door and a 20cm drawer front and connect them with a flat connector. Then you have a 160cm door. Maybe this will visually match the other fronts in the kitchen.
is very strange, since Ikea itself had numerous appliances for the 158 cm niche in Faktum. I recently saw no built-in fridge at all in the IKEA showroom where there wasn’t somewhere a pointless storage space because the doors are taller than the fridge. Unbelievable.
