We have already in our bathroom Grohe Concetto faucets and are also very satisfied with this. Great design, easy to care for, look after years of still great. So I also decided to use the kitchen for a Concetto faucet. I like the high spout, the pull-out mousseur, works fine, smooth and withdraws easily. The installation, however, turned out to be extremely difficult. We have a sink Franke Maris. But the sink and faucet not really fit each other. The fitting is somehow too big and the space under the sink too low for this fixture. Since improvisation is gefragt.Durch the type of attachment, the valve is not really just sitting on the sink. Which of course only on closer inspection that catches your eye. Why not five stars. Quality okay assembly a bit difficult ....
