Replacing irregular sink and tap
Countertops are custom cut for the space and the sink.  The space on the left where you currently have a drain pan will either be cut out (no countertop underneath) or ruined by glue and mismatching discoloration.
You will need a new countertop.  Go to a kitchen design store, which could be a hardware superstore with a kitchen department.   Choose a countertop and a sink.  They'll come measure your kitchen, cut the counter to fit the space and cut the opening for your chosen sink.  They will install it too, if you want.
