When you're choosing tiles for your home, preventing slips and falls might not be the first thing on your mind. It's easy to get caught up in picking the perfect color, shape, or finish.
While safety is a no-brainer for pool areas, it’s important to remember that kitchens and bathrooms can be slip hazards too. In fact, the World Health Organization (WHO) reports that over 30 million people around the world suffer falls each year that are severe enough to need medical attention.
Slip-resistant tiles can play a big role in preventing home accidents, keeping your house both beautiful and safe.
Find out exactly what slip resistance is, how porcelain tiles in Miami are rated for it, what factors affect their safety, and how to choose and enhance slip-resistant tiles for different areas of your home.

What is Slip Resistance?
Slip resistance refers to the ability of a surface to provide traction and prevent slipping, which is especially important in wet or high-traffic areas.
In simpler terms, a tile with high slip resistance will give your feet something to hold onto, reducing the chance of accidental slips. On the other hand, a tile with low slip resistance can be like walking on ice, making every step a potential hazard.
Slip resistance is often measured using two main systems:
Coefficient of Friction (COF)
The coefficient of friction measures the force required to move an object across a surface divided by the weight of the object. A higher COF indicates better slip resistance.
Imagine pushing a box across your kitchen floor. If the floor has a high COF, it means the box will need a lot of force to move, indicating good slip resistance. A low COF shows the box slides easily and suggests the floor could be slippery.
Dynamic Coefficient of Friction (DCOF)
The dynamic coefficient of friction measures the friction of a surface in motion, which is more reflective of real-world conditions where people walk and move on the tiles. Tiles with a high DCOF provide better traction when you’re moving, which is exactly what you want to prevent slips.
Both COF and DCOF ratings help determine how slip-resistant a tile is under different conditions, such as when it is wet or dry.

Slip Resistance Ratings for Porcelain Tiles
A tile might look perfect for a certain area of your home, but if its slip resistance rating isn’t high enough, it could end up being a risky and unsafe choice.
The ratings below will help you figure out how safe a tile will be in different conditions, making sure you pick the best option for areas prone to moisture or heavy foot traffic.
ANSI Standards
The American National Standards Institute (ANSI) is a non-profit organization that helps create and oversee standards for countless products and services in the U.S. They make sure everything from tiles to tech follows the same guidelines, ensuring safety and quality for everyone.
According to ANSI A137.1, which are the specifications for ceramic tiles, tile flooring products should have a DCOF of 0.42 or higher if they are meant to be used in flat indoor areas that can get wet.
The ANSI also divides tiles in five different categories, each with their own slip resistance recommendations:
ID (Level Interior and Dry)
These tiles are perfect for indoor areas with little to no water exposure, like living rooms and bedrooms. With a DCOF rating of 0.42 or greater when dry, they offer enough slip resistance for dry conditions, but might not be the best choice for places like kitchens or bathrooms where things can get wet.
IW (Level Interior and Wet)
IW tiles should have a DCOF rating of 0.42 or more when wet, and they are great for indoor areas that get wet regularly but not all the time, like kitchen floors or grocery store aisles. They provide good slip resistance to help prevent accidents in these environments.
IW+ (Level Interior and Wet Plus)
Tiles with an IW+ rating are designed for areas that are constantly wet during use, such as shower floors and locker rooms. They have excellent slip resistance to ensure safety even in the wettest indoor conditions.
EW (Exterior, Wet)
EW-rated tiles are made for outdoor areas that will get wet, like patios, walkways, and pool surrounds. They should have a DCOF of 0.60 or more while wet and can handle exposure to rain and other elements, offering great traction to prevent slips.
O/G (Oils/Greases)
Tiles with an O/G rating are specialized for areas exposed to oil or grease, like car shops and commercial kitchens. Therefore, they need to provide exceptional slip resistance to counteract the slippery nature of oils and grease and create a safe working environment.
The DCOF of these tiles should be 0.60 or greater when wet.
Testing Procedures
Porcelain tiles undergo rigorous testing to determine their slip resistance ratings. One of the key tests used is the DCOF AcuTest method, which is included in ANSI A137.1.
Here’s a simple rundown of how the test works:
- Preparation: The tile surface is thoroughly cleaned and dried to ensure it’s free from any dirt or contaminants. A standardized sensor is prepared to measure friction.
- Applying Soapy Water: The tile is wetted with a slightly soapy agent, simulating real-life scenarios where soap and water might be present.
- Testing: The sensor measures the force needed to move across the tile surface in these wet, soapy conditions. This simulates the experience of walking on the tile when it’s wet and slippery.
- Analysis: The results are analyzed to give a DCOF rating, which indicates how slip-resistant the tile is.
These tests ensure manufacturers can accurately label their products, helping consumers make informed decisions about which tiles are best suited for their needs.

Factors Affecting Slip Resistance of Porcelain Tiles
Several factors can influence the slip resistance of porcelain tiles, so you need to consider these when selecting tiles for your space.
Surface Texture and Finish
Tiles with a rough or textured surface provide more traction compared to smooth or polished tiles. Moreover, matte finishes are generally more slip-resistant than glossy finishes, which can become slippery when wet.
Environmental Factors
The environment where the tiles are installed also impacts their slip resistance. Wet conditions, such as bathrooms, kitchens, and outdoor areas, require tiles with higher slip resistance ratings. Even tiles that are safe in dry conditions can become hazardous when exposed to water or other liquids.
Maintenance and Cleanliness
Dirt, grease, and spills can reduce traction, increasing the risk of slips and falls. Regular cleaning with appropriate products helps maintain the surface texture and slip resistance of your tiles.
How to Choose Slip-Resistant Porcelain Tiles
Selecting the right porcelain tiles for your space involves considering the specific needs and conditions of the area.
Here are some tips to help you choose the best slip-resistant tiles for various environments:
Bathrooms
Bathrooms are prone to water spills and humidity, making slip-resistant tiles essential. Look for tiles with a DCOF rating of 0.42 or higher and a matte or textured finish to provide adequate traction even when wet.
Kitchens
Kitchens can also become slippery due to water, oils, and food spills. Choose tiles with a high slip resistance rating and easy-to-clean surfaces to ensure safety and hygiene.
Outdoor Spaces
Outdoor areas, such as patios and walkways, are exposed to the elements and can become wet and slippery.
Opt for tiles specifically designed for outdoor use, with a rough texture and high slip resistance rating to guarantee safety in all weather conditions.
High-Traffic Areas
For high-traffic areas like hallways and entryways, durability and slip resistance are key. Select tiles that can withstand heavy foot traffic and provide good traction to prevent accidents.
Elderly or Children’s Safety
If you have elderly family members or young children, prioritize slip-resistant tiles throughout your home. Consider installing tiles with high slip resistance ratings in all areas to minimize the risk of falls.
How to Enhance Slip Resistance of Existing Porcelain Tiles
If you already have porcelain tiles installed and are concerned about their slip resistance, these are some effective methods to make them even safer:
- Anti-Slip Treatments: Apply anti-slip treatments to create a rougher surface and increase traction without changing the appearance of your tiles.
- Mats and Rugs: Place non-slip mats and rugs in high-risk areas, such as entryways, bathrooms, and kitchens.
- Regular Maintenance: Keep your tiles clean by regularly removing dirt, grease, and spills with appropriate cleaning products to maintain their surface texture and slip resistance.
- Surface Etching: Consider surface etching, a method that uses chemicals or mechanical tools to roughen the tile surface and improve grip.
While some anti-slip treatments and maintenance practices can be done yourself, consulting with professionals can ensure the best results for enhancing the slip resistance of your floors.
