What Is a Slip Rating and Why Does It Matter for Tiles?

When selecting tiles for your home or commercial space, you might be focused on the style, colour, or texture. But there’s one element that matters just as much: safety.

What Is Tile Slip Rating?

A slip rating measures how resistant a tile surface is to slipping, especially when wet or smooth. It helps determine where a tile is safe to use, from bathrooms to commercial entries. Tiles are rated using tests like the ramp test (R rating) or pendulum test (P rating).

You’ll commonly see these ratings referenced in commercial specifications, but they’re just as important in residential spaces. Choosing a tile with the right slip resistance can save you money in the long run. Not to mention, it helps prevent unnecessary accidents.

Tiles for exterior floors or pool surrounds require a higher slip rating than indoor bathroom tiles, for example.

 

What Are the Main Types of Slip Ratings in Australia?

Australia uses a few different systems to assess slip resistance, each suited to different applications.

R Ratings (Ramp Test)

This test involves a person walking over a tile surface on an inclined ramp, usually coated in oil. As the ramp angle increases, the tester stops when they begin to slip. This generates a rating from R9 (least grip) to R13 (highest grip).

  • R9: Minimal slip resistance, best for dry indoor areas
  • R10–R11: Moderate to high grip, suitable for bathrooms and kitchens
  • R12–R13: Excellent grip, ideal for commercial kitchens and outdoor ramps

P Ratings (Wet Pendulum Test)

A more common standard for Australian regulations (AS 4586), this test uses a swinging pendulum to simulate a heel striking the tile. The resistance it encounters gives a P0–P5 rating.

  • P0–P2: Low slip resistance
  • P3: Acceptable for residential bathrooms
  • P4: Excellent for high-traffic public entries and commercial spaces
  • P5: Ideal for external spaces & around pools

These ratings help determine where tiles can be safely installed in both residential and public environments. You’ll often find P3 tiles in our interior floor tile collections.

 

Which Slip Ratings Are Best for Different Areas?

Slip-resistant tiles aren’t one-size-fits-all. Here’s how to decide what’s best depending on where the tiles will be used.

  • Outdoor areas, pool surrounds, commercial kitchens
    Use P4–P5 or R11+. These tiles offer maximum grip in wet, oily or unpredictable conditions.
  • Bathrooms and laundries
    Opt for P3–P4 or R10–R11. These resist slipping without being overly coarse underfoot.
  • Indoor living areas or bedrooms
    P2–P3 or R9–R10 is typically fine for dry, low-risk zones.

Keep in mind, a tile doesn’t have to feel rough to offer grip. Many textured tiles offer slip resistance through clever surface design, such as matt finishes, micro textures or subtle ridges.

 

Are Slip-Resistant Tiles Required for Commercial Spaces?

Yes, and in many cases, it’s non-negotiable. Commercial properties such as retail stores, healthcare facilities, hospitality venues and office buildings must meet slip resistance standards to comply with Australian building codes and OH&S regulations.

This means:

  • Selecting tiles with tested and certified slip ratings
  • Meeting minimum P-rating requirements for accessible spaces
  • Installing surfaces that maintain performance over time

Designers, specifiers and builders should refer to the NCC and AS 4586 when planning surfaces in these environments. Tiento’s commercial floor tile collection includes options that exceed these requirements without sacrificing style.
