Need to install kitchen sink in bathroom

[Billy Cova]

Hi. I need to install a kitchen sink in a bathroom. I’d like to use a standard bathroom sink drain/stopper but the hole in the sink is too large. Is there some sort of oversized flange or similar I can use to reduce the size of the hole to accept the smaller drain? Thanks!

What sort of kitchen sink do you wish to use in a bathroom.
