What is the purpose of a lavatory in a home?

A lavatory is primarily designed for personal hygiene, serving the essential function of washing hands and face. This includes providing access to clean water for these tasks, which is crucial for maintaining cleanliness and health.

While a lavatory may also feature a decorative aspect, that is not its main purpose. Similarly, while it can provide storage for toiletries, this is a secondary function rather than its primary intention. The lavatory's main role is to facilitate handwashing and face cleaning, which are fundamental activities in everyday personal care and sanitation. Hence, this makes it a vital component in any home.
