Porcelain vs Ceramic Tiles for Walls & Floors: Buyer Guide

Porcelain and ceramic are two of the most common tile materials, and they are often discussed as though one is always better than the other. In reality, the right choice depends on where the tile will be used, the exact product specification, the room, the surface format and the installation. A ceramic wall tile can be the ideal option for a splashback, while a porcelain product designed for wall and floor use may be more appropriate when the same look needs to continue underfoot. This guide compares the two materials using real products from the live JJ Building Materials wall and floor tiles range.

The product listing is always the final reference. Ranges can contain different sizes or materials, and suitability should be confirmed for the exact variant rather than inferred from the range name.

What Is a Ceramic Tile?

Ceramic tiles are made from ceramic materials that are formed and fired. Many dedicated wall tiles are ceramic because the material can be produced in a broad variety of colours, finishes and sizes. Ceramic wall tiles are often straightforward to cut compared with dense porcelain, which can be useful around sockets, niches and fittings.

However, a ceramic wall tile should not automatically be treated as a floor tile. Floors experience foot traffic and different loads, so the exact product needs to be specified for floor use. Some combined ranges can use ceramic for wall variants and porcelain for floor variants.

What Is a Porcelain Tile?

Porcelain is a type of ceramic material manufactured to be denser and with low water absorption. It is widely used for flooring and is also used on walls. Current examples in the JJ Building Materials collection include Johnson Tiles Kerastar Un-Glazed Porcelain Wall & Floor Tiles, Johnson Tiles Zeya Glazed Porcelain Wall & Floor Tiles and Johnson Tiles Refine Porcelain Wall & Floor Tiles.

Porcelain’s density can make it more demanding to cut. An installer may need suitable diamond cutting equipment, particularly for holes and intricate cuts. This practical difference should be considered in a DIY project or where a room has many obstacles.

Porcelain for Floors

Porcelain is common in floor tile ranges because it can be manufactured for demanding horizontal applications. This does not mean every porcelain tile is suitable for every floor. Surface performance, intended use and technical details vary between products.

Johnson Tiles Terrazzo 600x600mm Glazed Porcelain Wall & Floor Tiles are a current large square option. Johnson Tiles Orby 330x330mm Glazed Porcelain Wall & Floor Tiles provide a smaller square format. Both illustrate that porcelain is available at very different scales.

Porcelain on Walls

Porcelain can be installed on walls when the substrate and fixing system are suitable for the tile. Larger porcelain tiles can create fewer grout joints and a more continuous appearance, but their weight and density make substrate condition and adhesive selection important.

On a bathroom wall, a product such as Johnson Tiles Riverstone 600x300mm Glazed Porcelain Wall & Floor Tiles can create a broad rectangular grid. Check the wall flatness before installation because large pieces show background irregularities more readily.

Ceramic on Walls

Ceramic remains a strong wall choice where floor use is not required. It is especially common on kitchen splashbacks and bathroom walls. If you only need the wall, browse the dedicated wall tiles collection as well as combined wall-and-floor ranges. This can give you a wider choice of narrow bricks, squares and decorative wall formats.

The best buying approach is to start with the surface use. If a tile is only going on a wall, there is no need to reject ceramic simply because porcelain is denser.

Ranges That Combine Ceramic and Porcelain

Johnson Tiles Savoy Glazed Ceramic & Porcelain Wall & Floor Tiles show why buyers should inspect the exact variant. A named range can offer ceramic and porcelain products intended to coordinate while serving different surfaces or formats.

If you want one colour family across walls and floors, this type of range can be useful. But do not assume a wall variant can be moved to the floor simply because another variant in the range is porcelain. Treat each product selection individually.

Glazed Porcelain

Several current ranges are described as glazed porcelain, including Zeya, Riverstone, Terrazzo and Johnson Tiles Newark Glazed Porcelain Wall & Floor Tiles. A glaze provides the visible face and can support a range of colours and decorative effects.

The word glazed alone does not tell you everything about floor suitability, slip properties or maintenance. Those details need to come from the product’s technical information. Avoid broad assumptions based on the finish name.

Un-Glazed Porcelain

Kerastar and Johnson Tiles Parade Un-Glazed Porcelain Wall & Floor Tiles are identified in their titles as un-glazed porcelain. Un-glazed products have a different surface construction from glazed products and can create a more material-led appearance.

Again, check the exact specification for the intended location. “Un-glazed” is not a universal guarantee of any single performance characteristic.

Which Material Is Easier to Cut?

Typical ceramic wall tiles can often be cut more easily than dense porcelain. Porcelain may need a high-quality cutter, wet saw or appropriate diamond tooling. The difference becomes especially important around pipe holes, WC fixings, shower valves and multiple kitchen sockets.

If you are paying a professional installer, they will normally have appropriate equipment. DIY buyers should consider the cutting requirements before choosing a product purely on appearance.

Which Material Is Better for Large Formats?

Both materials can be made in larger sizes, but many wall-and-floor large formats are porcelain. Large tiles reduce grout lines but require a flat substrate and careful handling. A 600x600mm tile also creates large offcuts when the room dimensions do not align with the tile module.

Do not choose 600x600mm simply because it feels more premium. In a small cloakroom with many obstacles, a 330x330mm product may create easier, more balanced cuts.

Which Is Better for a Bathroom?

For floors, look for an exact product specified for floor use. For walls, both ceramic wall tiles and suitable porcelain tiles can work. A bathroom can therefore combine porcelain flooring with ceramic walls or use a wall-and-floor porcelain range throughout.

Waterproofing is not determined by the tile alone. Shower areas need the correct substrate, waterproofing or tanking where required, compatible adhesive, grout and sealant. The tile face is only one element of the system.

Which Is Better for a Kitchen?

On kitchen floors, verify floor suitability and choose a format that works with the cabinet layout and room shape. On splashbacks, glazed ceramic can be a practical and design-flexible option. If you want matching floor and wall surfaces, a combined range can simplify coordination.

Consider cleaning and grout. More small tiles mean more grout joints. A large porcelain floor can have a very different maintenance pattern from a narrow ceramic wall splashback.

Hallways and Busy Rooms

For entrance halls and busy areas, choose according to the exact product’s intended floor application and technical characteristics. Do not base the decision only on whether it is porcelain. The room’s traffic, cleaning routine and substrate all matter.

Underfloor Heating Considerations

If the floor includes underfloor heating, confirm compatibility across the complete system: tile, adhesive, grout, substrate preparation and heating manufacturer instructions. Porcelain is often used with tiled heated floors, but the exact installation needs to be specified rather than assumed.

How Material Affects Adhesive Choice

Dense porcelain and ceramic can require different fixing approaches depending on the substrate and tile size. Use adhesives recommended for the selected material and conditions. Large tiles may also influence trowel choice and coverage requirements.

Never select adhesive solely because it is already available on site. The fixing system is part of the finished floor or wall and should be chosen with the tile.

How Material Affects Drilling

Bathroom accessories, screens and kitchen fittings may require holes through completed tiles. Porcelain can be demanding to drill and should be approached with suitable equipment and technique. Plan fixing positions before installation where possible so cuts and holes can be coordinated safely.

Colour and Design Matter Too

Technical suitability narrows the options, but you still need a tile you want to live with. Terrazzo-inspired patterns, stone effects, simple neutrals and narrow formats all create different interiors. Compare products such as Terrazzo, Riverstone, Refine, Newark, Verso and Orby rather than reducing the choice to “porcelain or ceramic”.

Measuring Ceramic and Porcelain Tiles

The method is the same: calculate the tiled square metres, check the exact pack coverage and allow for cuts and breakages. Material does not remove the need for waste allowance. Large porcelain formats may create sizeable offcuts, while small ceramic layouts may generate many smaller cuts.

Cost Considerations Beyond the Tile Price

When comparing options, consider the full project rather than only the box price. Cutting tools, preparation, adhesive, grout, installation time and waste can all affect the final cost. A product that is inexpensive per square metre may not be the least expensive completed installation if the room creates extensive cutting.

Common Porcelain vs Ceramic Mistakes

Do not assume all porcelain is floor suitable, all ceramic is wall-only, every product in a named range has the same material or that a denser material automatically suits every project better. Read the exact product information and choose according to the actual surface and room.

Porcelain vs Ceramic FAQs

Is porcelain stronger than ceramic?

Porcelain is generally denser, but suitability should be judged from the specific tile’s intended use and technical information rather than material name alone.

Can ceramic tiles be used on floors?

Only when the exact ceramic product is specified for floor use. Do not put a wall-only ceramic tile on a floor.

Can porcelain floor tiles be used on walls?

Many wall-and-floor porcelain products are designed for both surfaces, but check the exact product and ensure the wall and fixing system are suitable.

Which is easier for DIY tiling?

Ceramic wall tiles can be easier to cut, while dense porcelain usually needs more capable tools. The room layout and tile size also affect difficulty.
