How To Check Tile Quality: A Complete Guide By Spenza Ceramics

Buying tiles is not just about choosing a colour or design that looks good. The tile also needs to be suitable for the space, easy to maintain, and capable of handling the conditions it will face. That is why knowing how to check tile quality before buying can save you from problems during installation and everyday use.

The easiest way to check tile quality is to look at the surface, colour, size, edges, flatness, and visible defects, and then check technical specifications such as water absorption, strength, abrasion resistance, and slip resistance. These checks can help you decide whether a tile is suitable for a bathroom, kitchen, living room, commercial space, or outdoor area.

In this guide, Spenza Ceramics explains how to check tile quality in simple, practical steps so you can choose tiles with greater confidence.

How Can You Tell If Tiles Are Good Quality?

You can tell if tiles are good quality by checking their appearance, dimensions, flatness, surface finish, and technical specifications. Understanding the different types of tiles can also help you evaluate which quality and performance characteristics are suitable for your specific application. A good tile should have a consistent appearance, properly finished edges, minimal visible defects, and performance characteristics that match its intended use.

Before purchasing tiles, check these important factors:

• Surface: Look for cracks, chips, pinholes, scratches, stains, or uneven finishing.
• Colour: Compare tiles from different boxes to identify noticeable shade variations.
• Size: Check whether the tiles have consistent dimensions.
• Edges: Make sure the edges are properly formed and do not show obvious damage.
• Flatness: Place tiles on a flat surface and check for noticeable warping or rocking.
• Water absorption: Review the manufacturer’s specifications, especially for moisture-prone areas.
• Strength: Check whether the tile’s strength is suitable for the expected use and traffic.
• Scratch and abrasion resistance: Consider these properties for floors and high-traffic areas.
• Slip resistance: Look for suitable slip-resistance properties when selecting tiles for wet or outdoor areas.

In short, don’t judge a tile only by how it looks. Check its physical condition and technical specifications together.

Understanding Tile Quality Standards

Tile quality is determined by more than appearance. Different tiles have different technical characteristics, and the right specifications depend on the type of tile and where it will be used.

Some of the important factors used when assessing tile quality include:

• Water absorption
• Dimensional accuracy
• Surface quality
• Breaking strength
• Abrasion resistance
• Scratch resistance
• Slip resistance
• Chemical and stain resistance

Standards such as ISO 13006 classify ceramic tiles according to characteristics including water absorption and other requirements. However, there is no single specification that makes every tile suitable for every application.

For example, a tile selected for a bathroom may have different requirements from one intended for a busy commercial floor. Therefore, always consider the tile type, application, manufacturer’s specifications, and installation conditions together.

The Basics: Visual Inspection

One of the simplest ways to perform a tile quality check is to inspect the tiles carefully before buying or installing them.

You do not need specialised equipment for this first step. A few minutes of careful inspection can help you spot visible defects and inconsistencies.

1. Surface Quality

Start by looking closely at the tile surface under good lighting.

Check for:

• Cracks
• Chips
• Pinholes
• Scratches
• Stains
• Uneven glazing
• Visible manufacturing defects

For textured tiles, some variation in surface texture may be intentional. The important thing is to check whether the finish is consistent with the product’s design and specifications.

2. Colour Consistency

Colour consistency is particularly important when several tiles are installed together. When selecting trending tile colours, make sure the chosen tiles also have consistent shades and finishes across different boxes.

Take tiles from different boxes and compare them side by side. Look for noticeable differences in:

• Shade
• Pattern
• Finish
• Surface appearance

3. Shape And Edges

Take two or more tiles and place them edge-to-edge.

Look for:

• Uneven edges
• Damaged corners
• Significant dimensional differences
• Gaps between tiles
• Misalignment

Small variations can depend on the tile type and manufacturing process, so compare what you see with the manufacturer’s stated specifications.

4. Flatness And Warping

Flatness is especially important for floor installations because noticeable warping can affect how tiles sit against the surface and each other.

Place the tile on a flat surface and check whether it rocks or leaves visible gaps. You can also compare multiple tiles together to identify noticeable differences.

For an accurate assessment, refer to the manufacturer’s dimensional and flatness specifications rather than relying only on a visual check.

Key Tile Quality Testing Methods

Visual inspection is a useful starting point, but technical specifications can tell you much more about how a tile is expected to perform.

Here are some of the important properties to check when evaluating tile quality.

1. Water Absorption Rate

Water absorption tells you how much water a tile can absorb under a specified test.

It is an important property when choosing tiles for areas that experience moisture, such as:

• Bathrooms
• Kitchens
• Balconies
• Terraces
• Outdoor areas

Lower water absorption can be beneficial for many moisture-exposed applications, but the ideal value depends on the tile classification, relevant standard, and intended use.

For this reason, don’t rely on a single number as a universal definition of good tile quality. Instead, check the manufacturer’s stated water absorption value and make sure the tile is appropriate for the area where you plan to use it.

2. Breaking Strength

Breaking strength indicates how much force a tile can withstand during a standardised test before breaking.

This is particularly relevant for floor tiles because floors may experience regular foot traffic and loads.

Rather than looking for one universal breaking-strength number, compare the manufacturer’s specification with the requirements of your project.

Factors such as tile type, size, thickness, installation method, and intended application can all affect performance.

3. Surface Hardness And Scratch Resistance

Scratch resistance tells you how well the tile surface can withstand everyday contact and abrasion.

You may find advice online suggesting that you scratch a tile with a knife or metal object. However, this is not a reliable substitute for a professional hardness or scratch-resistance test and can permanently damage the tile.

A better approach is to check the manufacturer’s technical specifications and relevant ratings.

For areas with heavy foot traffic, choose a tile whose surface performance is appropriate for the expected use.

4. PEI Rating And Abrasion Resistance

The PEI rating is used in relation to the abrasion resistance of glazed ceramic tiles.

It can help indicate whether a glazed tile is appropriate for different levels of use and foot traffic.

When choosing a floor tile, consider:

• Where the tile will be installed
• Expected foot traffic
• Whether the area is residential or commercial
• The manufacturer’s recommended application

The PEI rating should therefore be considered as part of the overall tile selection process rather than as the only measure of quality.

5. Slip Resistance

Slip resistance is an important consideration for areas where floors may become wet.

This includes:

• Bathrooms
• Kitchens
• Terraces
• Balconies
• Entrances
• Outdoor areas

The coefficient of friction (COF) is one measurement associated with slip performance. However, actual slip risk can also depend on factors such as water, contaminants, footwear, surface texture, and the testing method used.

For wet areas, select tiles with slip-resistance properties appropriate for the intended application and follow the manufacturer’s recommendations.

6. Chemical And Stain Resistance

Chemical and stain resistance can be important in kitchens, bathrooms, commercial spaces, and other areas where tiles may come into contact with spills or cleaning products.

Check the manufacturer’s technical information to understand the product’s resistance characteristics.

Avoid testing aggressive chemicals on tiles yourself. A harsh chemical can damage a sample without giving you a meaningful indication of standardised product performance.

How To Choose The Right Tile Quality For Different Spaces

There is no single definition of the “best” tile for every room. The right choice depends on how the space will be used.

1. Bathroom Tiles

Bathrooms regularly experience water and moisture. Pay attention to slip resistance, water-related performance, surface finish, and ease of maintenance when choosing bathroom floor tiles.

2. Kitchen Tiles

Kitchen surfaces can be exposed to water, food stains, grease, and frequent cleaning. Consider stain resistance, maintenance, surface characteristics, and suitability for the intended application.

3. Living Room And Bedroom Tiles

For living rooms and bedrooms, consider appearance, dimensional consistency, durability, maintenance, and the amount of foot traffic the floor is expected to receive.

4. Terrace And Outdoor Tiles

Outdoor areas can experience rain, sunlight, temperature changes, and moisture. Consider weather exposure, slip resistance, durability, and whether the product is specifically recommended for outdoor use.

5. Commercial Spaces

Commercial floors generally experience more traffic than residential spaces. Check abrasion resistance, strength, slip resistance, maintenance requirements, and the manufacturer’s recommended application before selecting tiles.
