What does a wet wall usually contain?

A wet wall typically contains both supply lines and soil and waste lines. This term refers to a section of a wall in a kitchen or bathroom where plumbing is concentrated. The wet wall is essential for the efficient installation of plumbing fixtures like sinks, dishwashers, and toilets, as it provides the necessary infrastructure for water supply and waste removal.

The inclusion of supply lines ensures that water can be delivered to appliances and fixtures, while the soil and waste lines are crucial for draining wastewater away from these fixtures. By having both types of lines within the wet wall, it allows for a more streamlined and compact approach to plumbing, which can save space and reduce the complexity of the plumbing layout in the overall kitchen design. This integration is crucial for meeting building codes and ensuring proper functionality.
