Introduction: Why EN 997 Matters in Today’s Sanitary Projects
In today’s construction landscape—be it hotels, residential towers, or public buildings—flush toilet performance is no longer just a detail. For international procurement professionals working with European suppliers or targeting compliance across multiple regions, understanding EN 997 is essential.
This European standard is more than a product label. It’s a performance-driven certification that measures how well a flush toilet actually performs in the real world—covering everything from flushing power to hygiene, water-saving capability, and durability.

Yet, many project managers or procurement teams still ask:
- What does EN 997 really certify?
- How does it compare to standards like EN 33 or ISO 30500?
- Which toilet types and technologies are eligible for it?
- And which brands already build products to meet or exceed EN 997?
This article unpacks EN 997 in practical terms, offering real-world use cases, comparative tables, and procurement tips for professionals looking to make informed buying decisions.
What Is EN 997?
EN 997 is a European performance standard developed by CEN (European Committee for Standardization) that applies to gravity-fed and pressure-assisted ceramic toilets with a close-coupled or independent cistern.
Unlike design-only standards (such as EN 33), EN 997 focuses on how a toilet actually works. It evaluates:
- Flushing efficiency (removing test materials in a single flush)
- Water seal depth to prevent odor backflow
- Cleanliness of the bowl post-flush
- Noise levels during operation
- Water usage, including dual-flush systems (e.g., 4/2.6L and 6/3L)
This standard helps ensure high performance across different building environments—from airports and resorts to hospitals and residential units.
