Anti-Slip Tile P Ratings in Singapore
When choosing floor tiles for wet or spill-prone areas such as bathrooms, kitchens and outdoor spaces, slip resistance is an important factor to consider alongside design and functionality.
The P Rating is a slip-resistance classification determined through the Wet Pendulum Test, which assesses how resistant a surface is to slipping under wet conditions. In Singapore, slip resistance classification is covered under SS 485:2022, which adopts the test method from AS 4586:2013.
The P Rating ranges from P0 to P5 , with a higher P value indicating greater slip resistance under wet conditions:
- P0 : represents the lowest classification
- P5 : represents the highest classification

These P-Ratings help builders, designers, and homeowners choose the right materials to enhance both safety and compliance in residential and commercial projects.
Whether you're planning a home renovation or a commercial fit-out, understanding these ratings ensures that your flooring choices meet both aesthetic and safety standards.
How to Choose the Right P Rating?
Bedrooms & Living Areas

Opt for P1-P2 —ideal for dry-foot environments where spills are unlikely.
Kitchens & Hallways

Choose P3 rating to ensure safety in areas that see occasional water or mess.
Bathrooms & Laundry Rooms

Use P4 —perfect for spots frequently exposed to moisture.
Sheltered Outdoor Spaces (e.g. balconies, patios)

Select P4 to handle exposure to outdoor rain and humidity.
Fully Exposed Outdoor Areas (e.g. pool surrounds)

Go with P5 for the highest safety in constantly wet, high-risk zones.
Why Not Always Go for P5?
- Texture trade-offs : P5-rated surfaces are often very rough—great for external ramps but less ideal for areas like bathrooms or barefoot zones .
- Cleaning considerations : Higher ratings mean more texture, which can gather dirt and require extra maintenance
Choosing the right slip rating guarantees safety, regulatory compliance, and long-term durability. For optimal performance, it's essential to understand and apply the appropriate P-ratings, whether you're installing flooring indoors, outdoors, in barefoot zones, or industrial environments.
