How many oxygen masks are available in the lavatory of a 737 aircraft?

In a Boeing 737 aircraft, there are typically two oxygen masks available in the lavatory. These masks are part of the emergency equipment provided to ensure passenger safety in the event of a drop in cabin pressure. The presence of two masks allows for use by multiple individuals simultaneously if necessary, such as during a situation where a crew member may need to assist a passenger in the lavatory during an emergency. This redundancy is important for maintaining safety standards and ensuring that emergency procedures can be effectively carried out.
