Hi there, did you mean to attach photos? I don't think they posted. I know this is from a while back but I'm interested to hear what you ended up choosing.

What is going on with the cabinet, or is there a cabinet? Does it have doors that create a center line? Does it have an opening for a basin or is it a vessel sink basin (a bowl that sits on top of the cabinet). A picture would help us help you in the best possible way, but not having seen it- 99.9% of basins must be centered under the faucet. For splashing and for aesthetics. Exceptions are rare. Good luck! I hope to see a pic and get more specific!

The other side of my kitchen will look like this (picture attached)

Hello Rola, You can go for a slightly bigger one upto 21 inches. See if you likes sinks with drain board. Thanks, Amit Cornerstone Designs Bangalore
