Over the very many years that I have been renovating houses or doing up one for ourselevs, Magnet kitchens were my Go-To. Currently on the seventh and it has been a disaster from start to finish. To be fair, Magnet have or are in the process of resolving all the various issues, faults, broken bits and scratched frontals but the latest 'find' is, I think insoluble and a perfect storm or SNAFU.
When I started fitting the kitchen I noticed that the tolerances on the cabinet widths was a bit, shall we say, elastic. Never 600mm but 601mm or 601.5mm. Ditto 800mm cabinets. Not a problem in a run along a wall but we lso have an island unit that is single cabinet deep. So there is a breakfast bar panel at the back. It is exactly 2m long. You can see where I am going with this.
Taken the first cabinet

Then the middle cabinet

Then the final cabinet

and adding up all those extra mm means that when you exactly align one end of the bar panel with an end cabinet, when you get to the other end the panel is not long enough

I think that a 2m breakfast bar panel is the longest and so no chance of getting it and cutting to length. The cut edge not being an issue as it will be covered by the end panel.
