We have already paid over €1000 for an 80 cm and a 40 cm tall cabinet from the Ikea kitchen series (they are still in our utility room) and had to assemble them ourselves. I don't really find the €4000 for our complete utility room including all the compartments, drawers, stainless steel sink, waste separation system, and installation expensive. The quality of the drawers, etc. is at least two levels above Ikea's with Schüller.
What can be discussed are the cabinets, because whether premium, Ikea, Mittendrin, or custom-made, they are all just plywood and way too expensive.
