BREDSKÄR sink hole diameter

Hello fans.

Unfortunately, I cannot find any information from Ikea about the hole diameter of a Bredskär sink. That is, when the siphon is removed. I only find information about the diameter at the top of the siphon (apparently 119 mm), but about the hole - nothing. Can someone help me?

Many thanks, Peter

For all sinks from IKEA, it is 3 1/2".

Great, IKEA expert, thank you very, very much! :)

That was exactly my hope! Hehehe!

Thanks again!

Best regards, Peter

I just hope you don't want to hang some kind of electric American mess underneath it.
