Porcelain tiles are made from refined clay, usually kaolin, combined with feldspar and quartz, and fired at extremely high temperatures. The result is a dense, durable tile that performs exceptionally well in both residential and commercial spaces.
What makes porcelain unique is its very low porosity. Through a process called vitrification, the tile becomes almost glass-like, which helps it resist moisture, stains, and wear. That’s why it’s so commonly used in kitchens, bathrooms, hallways, and outdoor areas.
Available in a wide range of finishes—from stone-look to polished marble effect—porcelain tiles offer a balance of strength and design flexibility. Large-format tiles such as 120x120cm are especially popular in modern interiors, while 60x60cm formats remain a go-to choice for everyday applications.
Porcelain vs Ceramic – What’s the Real Difference?
Porcelain and ceramic tiles may look similar at a glance, but they behave very differently over time. Porcelain is denser, stronger, and more moisture-resistant, which makes it suitable for areas with high foot traffic or exposure to water.
Ceramic tiles tend to be more porous and easier to cut, which can be useful in smaller DIY installations. However, porcelain's superior strength makes it a better long-term choice for kitchens, bathrooms, patios, and even commercial settings.
Tiles in marble, stone, and concrete-effect finishes are widely available in porcelain formats, offering the look of natural materials without the high maintenance or sealing requirements often associated with real stone.
Where Can You Use Porcelain Tiles?
Porcelain tiles are incredibly versatile and well-suited to both floors and walls across the home. With their durability, low maintenance, and wide range of design options, they’re a smart solution for nearly every interior space—and many exterior applications as well.
Kitchens
In kitchens, porcelain works beautifully on both floors and walls. On the floor, it stands up to spills, foot traffic, and moving furniture. On the wall, it’s perfect behind hobs and sinks, offering a hygienic surface that’s easy to wipe clean. Stone and marble-effect finishes can create a premium look, while textured or concrete-inspired styles are ideal for more contemporary kitchens.
Bathrooms
Bathrooms are one of the most common places to use porcelain tiles. Their resistance to moisture and mould makes them an excellent choice for floors, walls, and even inside showers. Large-format tiles reduce grout lines and create a clean, seamless surface. Matte finishes are often preferred in wet zones for added slip resistance.
Hallways, Entranceways, and Utility Rooms
These high-traffic areas benefit from porcelain’s strength and resistance to wear. For added visual interest, patterned tiles or larger formats like 60x120cm can elevate the look while remaining easy to maintain.
Walls
Feature walls in lounges, behind bathtubs, or above fireplaces can be finished in marble-effect or textured porcelain to create visual depth and a high-end feel. Porcelain is also ideal for walls in utility rooms, cloakrooms, and pantries due to its easy-to-clean surface.
Outdoors
Porcelain tiles can be used on patios, balconies, and pathways, provided they are slip-resistant and properly installed. While 20mm thickness is common outdoors, even 9mm tiles can perform well when laid on a solid substrate with suitable adhesive and grout. UV and frost resistance make them ideal for changing weather conditions.
Looks and Styles – Not Just “One Look”
One of the best things about porcelain tiles is how easily they combine durability with design. From minimalist apartments to heritage-style homes, the right finish can shape the space while offering everyday practicality.
Concrete-Look Tiles
These are known for their neutral, modern tone and soft matte textures, ideal for open-plan areas, kitchens, and utility spaces. Their simplicity complements most interiors without overpowering them.
Marble-Effect Tiles
Marble-look porcelain brings elegance without the maintenance. These tiles replicate natural veining and shine, making them ideal for bathrooms, hallways, or feature walls in luxury settings.
Stone-Look Tiles
Inspired by natural stone, these tiles offer texture and warmth. They're perfect for relaxed yet sophisticated spaces like bathrooms and entranceways.
Wood-Effect Tiles
Wood-look porcelain gives you the appearance of real timber with the benefit of waterproof, scratch-resistant performance. It’s great for kitchens, bedrooms, and underfloor heating areas.
Patterned Tiles
From vintage motifs to bold geometric designs, patterned porcelain tiles are ideal for smaller floors or feature walls. Unlike traditional cement tiles, they combine rich design with low maintenance.
Are Porcelain Tiles Really That Durable and Easy to Maintain?
Yes. Porcelain tiles are dense, scratch-resistant, and suitable for high-traffic areas. Their low porosity makes them resistant to water, stains, frost, and UV exposure. A typical PEI rating of 4 or 5 means they’re suitable for kitchens, bathrooms, and commercial spaces.
Cleaning is simple: regular sweeping and mopping with warm water and a pH-neutral cleaner is usually enough. No sealing is needed for most glazed or polished surfaces, and tougher stains can be handled with diluted tile-safe solutions.
How Much Do Porcelain Tiles Cost?
Prices vary by size, style, and finish. Standard indoor tiles (e.g. 60x60cm) start around £30–£40/m². Mid-range marble or stone-look options in larger formats may range from £35–£50/m². Premium large-format or outdoor tiles can exceed £60/m². Always consider installation materials (adhesive, grout, trims) when budgeting.
What’s Involved in Installing Porcelain Tiles?
Installation requires a level surface and the right materials. Use a flexible, cement-based adhesive rated for porcelain. For precision, cutting should be done with a wet tile saw and a diamond blade. Grout types depend on the space — standard grout is used for dry zones, and water-resistant or epoxy grout is used for wet areas. Outdoors, solid bases and full bed adhesive are essential for long-term durability.
FAQs About Porcelain Tiles
Are porcelain tiles slippery when wet?
It depends on the finish. Polished tiles can be slippery, while matt and textured finishes offer better grip. Always check the R-rating for slip resistance.
Do porcelain tiles fade in the sun?
No. They are UV-resistant and suitable for use in sunrooms, balconies, and patios.
Do porcelain tiles need sealing?
Most do not. Their low porosity eliminates the need for sealing, though grout lines or unglazed/textured tiles may benefit from occasional sealing.
Can you use porcelain tiles with underfloor heating?
Yes. Porcelain is heat-conductive and works well with electric or water-based underfloor heating systems.
What’s the difference between glazed and full-body porcelain?
Glazed porcelain has a printed surface layer, while full-body porcelain has consistent colour and texture throughout. Chips are less noticeable on full-body tiles.
How do you cut porcelain tiles?
Use a wet tile saw with a diamond blade for best results, especially for thick or textured tiles.
How do you drill into porcelain tiles?
Use a diamond-tipped drill bit at low speed. Avoid hammer settings, and keep the area cool with water.
How do you clean porcelain tiles?
Use a pH-neutral cleaner and a soft mop. Avoid wax-based or abrasive products. For polished finishes, use a microfiber mop for added shine.
How do you clean outdoor porcelain tiles?
Sweep regularly. For deep cleaning, use a tile-safe patio cleaner and a stiff brush. Rinse thoroughly and avoid acid-based products.
How do I remove mud stains from porcelain patio tiles?
Use a non-acidic degreaser diluted in warm water. Scrub with a firm brush and rinse thoroughly.
Can porcelain tiles be laid on sand and cement?
Not recommended. Porcelain requires a solid base and flexible adhesive to ensure proper bonding and long-term stability.
