While shopping for bathroom tiles<\/strong><\/a> for your wet room or kitchen tiles, you may have come across codes such as R9, R10, and R11. You may have no idea what this actually means, but it is one of the technical tile specifications that ensures your safety. These are R-ratings, used to measure the slip resistance of the tiles and whether it is suitable for a specific space or not.<\/p>\n\n\n\n

R9 slip rating provides minimal slip resistance; thus is ideal for dry indoor spaces like living rooms, dining rooms and bathrooms with a mat. R10 slip rating provides slightly better slip resistance, best for standard bathroom and kitchen floor use. R11 slip rating provides the safest foot grip, making it ideal for wet rooms and walk-in showers.<\/p>\n\n\n\n

This guide breaks down what R9, R10, and R11 antislip actually mean, where UK safety guidance points, and which rating makes sense for your bathroom.<\/p>\n\n\n\n

<\/a>What Are Tile Slip Ratings<\/h2>\n\n\n\n
Slip Rating<\/strong><\/td>Slip Resistance<\/strong><\/td>Ideal For<\/strong><\/td>Visual Example<\/strong><\/td><\/tr>
R9<\/strong><\/td>Minimal<\/td>Dry indoor spaces; bathrooms with mats<\/td><\/td><\/tr>

R11<\/strong><\/td>High<\/td>Wet rooms; walk-in showers<\/td><\/td><\/tr><\/thead><\/table><\/figure>\n\n\n\n

The R rating system (R9 to R13) comes from a German test standard, DIN 51130<\/strong><\/a>. An operator wears shoes and walks across a tiled ramp coated in oil. The angle at which they start to slip determines the rating. The higher the number, the steeper the ramp, the more resistant the tile.<\/p>\n\n\n\n

The R rating system (R9 to R13) comes from a German test standard, DIN 51130<\/strong><\/a>. An operator wears shoes and walks across a tiled ramp coated in oil. The angle at which they start to slip determines the rating. The higher the number, the steeper the ramp, the more resistant the tile.<\/p>\n\n\n\n

<\/a>Pendulum Test Values (PTV) Scale UK<\/h3>\n\n\n\n

 In the UK, slip resistance is usually measured using Pendulum Test Values (PTV), based on BS 7976<\/strong><\/a>. This is a different test method entirely. A pendulum swings across the tile surface and measures resistance, usually in wet conditions with a rubber slider.<\/p>\n\n\n\n

R ratings and PTV aren’t directly interchangeable; a tile’s R rating won’t reliably tell you its exact PTV score, so don’t treat one as a substitute for the other if a supplier only provides one figure.<\/p>\n\n\n\n

The Health and Safety Executive (HSE)<\/strong><\/a> recommends a minimum PTV of 36 for areas at high risk of slipping when wet; a useful benchmark if a tile’s spec sheet includes it.<\/p>\n\n\n\n

<\/a>R9 Bathroom Tiles: Light Slip Resistance<\/h2>\n\n\n\n

R9 slip rating works best in dryindoor spaces; living rooms, dining areas, bedrooms. Some suppliers list R9 for bathrooms, but the caveat matters: it’s really suited to dry bathroom floors, or bathrooms used alongside a bath mat near the shower or bath.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
Pros<\/strong><\/td>Cons<\/strong><\/td><\/tr>
Wider choice of smooth, polished, and matt finishes<\/td>Not rated for standing water; a wet R9 floor offers minimal grip<\/td><\/tr>
Often the most budget-friendly option<\/td>Most UK suppliers recommend a bath mat as standard if you go this route<\/td><\/tr>
Easier to clean, since there’s less surface texture to trap grime<\/td>Not a safe standalone choice for family bathrooms with children or older adults<\/td><\/tr><\/thead><\/table><\/figure>\n\n\n\n

R10 Bathroom Tiles: Balanced Safety & Comfort<\/h2>\n\n\n\n

R10 is the realistic baseline most suppliers specify for UK bathroom floors. R10 anti-slip tiles offer moderate slip resistance suited to occasional splashes and spills, which is normal in most bathrooms. But remember, it is not ideal for a shower that drains directly onto the floor.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
Pros<\/strong><\/td>Cons<\/strong><\/td><\/tr>
Safe for the majority of domestic bathrooms with typical use<\/td>Not necessarily enough for wet rooms or showers with no enclosure, where water sits on the floor for longer<\/td><\/tr>
Still available in a good range of styles, including wood-effect and stone-effect porcelain<\/td>Slightly more texture than R9, which can affect cleaning in grout lines<\/td><\/tr>
A sensible middle ground between look and safety<\/td> <\/td><\/tr><\/thead><\/table><\/figure>\n\n\n\n

R10 is also the rating most commonly used for <\/a>kitchen tiles<\/strong><\/a>, since kitchens face similar occasional-splash conditions to a standard bathroom.<\/p>\n\n\n\n

<\/a>R11 Bathroom Tiles: High Slip Resistance<\/h2>\n\n\n\n

R11 is where suppliers start recommending <\/a>anti-slip tiles<\/strong><\/a> for wet rooms, walk-in showers, and bathrooms used by children or elderly family members. R11 anti-slip tiles are best for anywhere water regularly covers the floor rather than just splashing it.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
Pros<\/strong><\/td>Cons<\/strong><\/td><\/tr>
Meaningful grip in genuinely wet conditions, in both <\/a>porcelain tiles<\/strong><\/a> and other finishes<\/td>More textured surface, which can feel rougher underfoot and is slightly harder to keep spotless<\/td><\/tr>
The standard suppliers point to for wet room installations<\/td>Fewer ultra-glossy or highly polished finishes available at this rating<\/td><\/tr>
Suitable for both indoor wet areas and outdoor paving<\/strong><\/a> in thicker versions, such as patios and paths<\/td> <\/td><\/tr><\/thead><\/table><\/figure>\n\n\n\n

Choosing the Right Slip Rating for Your Bathroom<\/h2>\n\n\n\n

There’s no single “correct” answer; it depends on how the room is actually used. Some points worth weighing up:<\/p>\n\n\n\n
