Floor Drain
BUILDING MATERIALS & CONSTRUCTIONintermediate
Definition
Grate or shower drain — an opening in the floor with a removable strainer that allows water to drain away. Floor drains are used in bathrooms, kitchens, and wet areas to accommodate water spillage and to support hose-based cleaning. Proper floor slope toward the drain and a trap (P-trap) below the grate are essential to prevent drain flies and sewer gases.
Example
An Indonesian bathroom floor is sloped at 1–2% toward a floor drain equipped with a removable grate and a P-trap below — allowing spillage from showers and bucket cleaning to drain away while remaining dry for most of the day.
