My master bedroom vanity is 88" wide. It's obviously a double sink vanity and I'm trying to decide between 18" wide sinks or 23.5" sinks.

Benefit of the smaller sink of course is that it will give me more counter space. But I'm worried they might look too small on such a big vanity. Is giving up a foot of counter space worth it for the aesthetics of a bigger sink?

Not sure if it matters but if anyone asks, the sinks are rectangular undermount and the style is modern.
