Hello,
it actually depends on the brand of the kitchen, the running meters, and the appliances you want to afford.
Current example: We were supposed to get the Siemens Studio-Line cooktop for €2200, which is not available in the foreseeable future because Siemens currently produces only 9 cooktops every 3 weeks and there is a three-digit backlog!!
Now we were forced to buy what the market offers - namely a Berbel BKF 83 DLP U for €3500.
I wouldn’t have done that in advance, but in an emergency you have to choose the lesser of two evils.
We are paying just under €20k for almost 8 meters Nobilia with otherwise Siemens Studio-Line appliances, Berbel cooktop, and granite worktop.
To be fair: The kitchen contract was signed 2 years ago.
Important for you: There will always be someone who wants a kitchen for 20k/30k/50k etc, but don’t be dazzled. Set yourself a limit plus 10%, then you should do well. The brands you described are top, so I don’t expect total failures now.
