It's what was in the house when we moved in. It's a tiny bathroom, and the sink is pretty small so should work well for the space. The missus wants to keep some retro touches. The sink is probably ~25-30 years newer than the house. I'm guessing that someone added indoor plumbing and this was probably the original bathroom sink when they did.

A buddy liked to use silicone glue in plumbing but I've never tried that.

You could add a fat o-ring to take up a lot of the empty space.

I am OK to use silicone in some places, but for this spot, I'm OK with using the putty.
