Really a pity, but I have already found a cheap replacement on eBay... :D
The only thing that is not really decided yet is the sink. At Ikea, only the white ceramic sink "domsjö" would be an option. However, we are not quite sure about its durability regarding impact resistance, etc. On the other hand, you could probably buy the sink again at IKEA for little money in years to come.
An alternative sink would be the significantly more expensive Franke 114.0277.695 in the color Magnolia.
Matching that is the even more expensive faucet in the same color: Franke 115.0282.370.
But we are still in the consideration phase... ;)
I think the purchase will be made in about 4-6 weeks. Since the fronts currently have a delivery time of about 8 weeks, we would then have 8 weeks to prepare the room accordingly. So knock out the old kitchen, remove wall tiles, remove wallpaper and put new wallpaper on, paint the ceiling, reroute connections, etc.
We might even lay new floor tiles, but for that the floor would have to be completely removed, insulation and screed redone, since the previous tiles were only laid in "speiß," "spieß," mortar, or whatever that material is called depending on the region.
