Hi LotF, hi Ikea expert,
I still have Faktum cabinets and, by clever positioning, 10 years ago we were able to cover the Ärlig fronts (16mm deep) with a standard 60cm countertop from the hardware store. After changing the fronts, Norje (19mm deep) unfortunately now protrudes. At our hardware stores, I can unfortunately only still find 60cm countertops. Other depths are only available by order, and in that case IKEA is probably cheaper for me. If I use laminate (the ideas with stone and acrylic are no longer current), I can take a standard countertop and a Personlig that have the same design; at the hardware store, both would have to be ordered.
Perhaps as a general suggestion: friends of ours (hobby cooks with a son in culinary training) recently got a countertop with a 5cm overhang and are super enthusiastic because hardly anything splashes onto the fronts anymore. At the moment, countertops with only a slight overhang are modern not only at Ikea; you can also order a deeper size at Ikea.
Since we are not hobby cooks, just a 3-kids-standard basic supply, Metod on Faktum is sufficient for me.
Best regards
