# Pressure of a liquid when discussing boiling

It's said that at boiling point the pressure of the liquid is equal to the pressure of its vapor. That way, bubbles can form in the liquid phase. However, unless I'm mistaken, while the pressure of a gas is (mostly) uniform, the pressure of a liquid changes appreciably with depth. How can one talk about the pressure of the liquid being equal to the pressure of its vapor when the pressure of the liquid doesn't take on a single fixed value?

The atmospheric pressure is about $$14.7$$psi. The pressure at the bottom of a kettle, filled with $$6$$" of water, is going to be about $$0.21$$psi or $$1.4$$% greater than the pressure at the top.
