Slip Resistance of Ceramic and Porcelain Tiles

When choosing floor tiles, especially for bathrooms, kitchens, or outdoor areas, slip resistance is something worth considering. Different tiles provide different levels of grip depending on the finish, texture, and where they are used.

What is Slip Resistance?

Slip resistance refers to how much grip a tile has underfoot. Some tiles are smoother and can become slippery when wet, while others are designed to provide extra grip and safety.

Things that can affect slip resistance include:

• Water on the surface
• Dirt or cleaning products
• Footwear
• Indoor or outdoor use
• The finish of the tile

Generally, matt and textured tiles offer better grip than polished tiles.

What Are R Ratings?

Most tiles are tested and given an “R Rating” to show their level of slip resistance. The higher the number, the more grip the tile provides.

R Ratings are commonly used across Europe and are particularly useful when comparing tiles for different spaces.

What is a PTV Rating?

Another important measurement is the PTV Rating, which stands for Pendulum Test Value. This test measures how slippery a surface is when walked on.

Unlike R Ratings, PTV Ratings focus more on real life slip risk, especially in wet conditions.

For most bathrooms, kitchens, and busy areas, a PTV rating of 36 or higher is usually recommended.

R Ratings vs PTV Ratings

Both ratings measure slip resistance, but they are tested differently.

• R Ratings are based on grip using an inclined ramp test
• PTV Ratings are based on how slippery the surface feels underfoot

Many tile manufacturers now provide both ratings to help customers choose the right tile for their space.

Which Tile Should I Choose?

For most homes:

• R9 or R10 tiles are suitable for normal indoor spaces
• R11 tiles are ideal for wetrooms and outdoor areas
• PTV 36+ is recommended where extra safety is needed
• Matt and textured finishes usually offer better grip than polished tiles

Modern porcelain tiles can now provide excellent slip resistance while still maintaining a smooth and stylish finish.

Are Polished Tiles Slippery?

Polished tiles can become slippery when wet, especially in bathrooms or outdoor areas. While they create a luxurious look, they may not always be the best option for high moisture spaces.

For areas exposed to water regularly, matt or textured tiles are usually the safer choice.

Slip Resistance for Bathrooms and Wetrooms

Bathrooms and wetrooms require extra attention because floors are frequently wet.

For these areas, it is generally recommended to choose:

• Matt porcelain tiles
• Textured finishes
• R11 rated tiles
• PTV 36+ tiles for improved safety

This helps create a safer and more practical surface while still achieving a modern look.
