Herein, does a sink need an overflow?
An overflow is an optional feature found in some bathroom sinks. As the name suggests, it helps prevent the sink from overflowing. An overflow is a small opening in the sink, and it works by letting air flow into the drain while the sink is full of water so the sink drains water more quickly.
Furthermore, why does a kitchen sink not have an overflow? The first obvious reason is simple: It is very tough to overfill a kitchen sink because they are so large. Also, since most kitchen sinks are two-bowl designs and the divider is lower in the middle than the sides, the second bowl will act as a backup for any spilled water, and an overflow would go down that drain.
