Hello,
we solved our "wardrobe problems" a bit differently.
Since our kitchen was made and installed by a carpenter who told us that he works with standard widths and heights as long as possible and then makes the rest to measure, we also requested and ordered our built-in wardrobe, the room divider wardrobe bedroom / dressing room, as well as all bathroom furniture (vanity unit, mirror cabinet, and wall-mounted sideboard) from him.
The whole thing was then, with better quality, even a bit cheaper (and above all more precisely fitting) than everything else we discovered.
Maybe that’s an option for you too...
Regards,
Dirk
