Is there a standard sink size? I have want a sunk that can be easily replaced if nesseray

[Brighterblighter]

Does such a thing exist please?
I'm getting a new kitchen and the current sink has been impossible to replace!

If you have an 800 wide one, you will have a hell of a job getting a replacement, I found that out to my cost, finally found one but much more expensive than standard. I think they are mostly 860 or 900
