overflow drain
Tub safety hole
An overflow drain is a secondary drain positioned near the top of a sink, bathtub, or basin to prevent water from spilling over the edge.
When the main drain is plugged or blocked, rising water escapes through the overflow before reaching the rim: The overflow drain kept the bathroom from flooding when I forgot the faucet was running.
