How many oxygen masks are in each lavatory?

Explanation:
Oxygen must be readily available in enclosed spaces like a lavatory during depressurization, so the lavatory is equipped with its own oxygen supply. On the 737-700, each lavatory has two oxygen masks connected to the emergency system. Having two masks ensures there’s quick access for the person in the lavatory and provides redundancy in case one mask isn’t immediately usable or if more than one person is in the area needing oxygen. This setup speeds access and helps guarantee oxygen availability in that confined space, which is why two masks per lavatory is the correct configuration.
