Haitong sink (help identify)

[Bogie]

Hi. I need to replace an undermounted bathroom sink and am unsure of the manufacturer. The trademark on the sink is Haitong, but I can't find any information on it. If anyone is familiar with the manufacturer, I will be greatly appreciative.
Thanks!

Like havasu said you just need to get some measurements. Their usually either round or oval
