Where can I get large format porcelain sheets from?

Large format porcelain sheets are increasingly popular with homeowners, architects, and designers who want a clean, modern finish without the visual interruption of grout lines. They create a sleek look on walls and floors, are easy to maintain, and can replicate the appearance of natural stone or marble at a fraction of the upkeep.

In the tile industry, “large format” refers to porcelain sheets that are much bigger than standard tiles. Typical sizes include 3000 × 1000 mm and 2600 × 1200 mm, often produced in a slim 6 mm thickness for lightweight uses such as cladding and wall applications. These oversized sheets make it possible to cover entire walls or large surfaces in a single span, creating a sleek, seamless look with minimal joints.

Different thicknesses are also available depending on the application — thinner sheets are ideal for vertical cladding, while thicker formats are better suited to flooring, steps, and outdoor projects where additional strength is required. This versatility allows large-format porcelain to work in almost any setting, whether it’s a private home or a demanding commercial space.

Large porcelain sheets are incredibly versatile. Inside the home, they’re perfect for bathrooms, wet rooms, splashbacks, kitchen walls, and fireplace surrounds. The continuous surface makes cleaning easier and brings a luxury feel to everyday spaces.

They’re also well suited to commercial interiors, such as hotel lobbies, restaurants, and retail displays, where durability and visual impact are both important. For those looking to extend the same look outdoors, porcelain sheets can be combined with thicker porcelain tiles for patios, terraces, and pool surrounds, creating a flowing connection between inside and outside spaces.

The main reason homeowners and designers turn to large-format porcelain is the minimal use of grout. With fewer joints, surfaces look calmer, more spacious, and much easier to keep clean. This seamless effect works especially well in kitchens, bathrooms, and open-plan living spaces where clean lines and simplicity are key.

The impressive scale of these slabs also unlocks new creative opportunities. Oversized sheets can be used to achieve striking wall and floor finishes that emulate quarried stone, polished marble, or even raw industrial concrete — but without the natural flaws or inconsistencies that stone sometimes carries. For anyone seeking a sleek, continuous aesthetic, large-format porcelain delivers exceptional results.

Porcelain also brings practical benefits. Unlike natural stone, it does not need sealing and provides a consistent finish across every sheet. It’s resistant to water, stains, and day-to-day wear, making it an excellent option for busy family homes, hospitality interiors, and commercial spaces where strength and low maintenance are essential. This combination of durability and style is why large-format porcelain is such a versatile material in contemporary design

Large-format porcelain slabs need expert cutting and careful handling. In our workshop, we use advanced water-jet technology and specialist porcelain machinery to achieve flawless precision. This allows us to produce socket apertures, mitred corners, shower niches, splashback cut-outs, step nosings, and a wide range of bespoke details.

By preparing the slabs in our workshop, each piece arrives on site ready for installation, minimising the need for risky on-site cutting. For projects where accuracy is critical — like aligning book-matched porcelain or maintaining sharp mitres — workshop fabrication provides the most reliable and efficient solution.

Because the sheets are large and slim, careful planning is essential. Substrates must be flat and stable, adhesives chosen for full coverage, and movement joints included to avoid stress over time.

Specialist handling frames, suction lifters, and appropriate transport are strongly recommended to protect the edges and faces of the sheets. Installers should be confident working with large format products; where they aren’t, pre-cut pieces make the process easier and safer.

Installing large-format porcelain sheets usually costs more than regular tiles, because the size, weight and precision required introduce more challenges. Here’s what tends to push the price up, and some rough ideas of what a homeowner might expect to pay in the UK:

Porcelain is among the easiest surfaces to maintain. Being non-porous, it resists stains and can be cleaned effortlessly with a mild pH-neutral cleaner. This makes it a perfect choice for high-traffic kitchens and bathrooms where spills happen frequently.

For textured porcelain finishes, it’s best to avoid abrasive pads and instead use soft cloths or gentle brushes to protect the surface. With simple, routine cleaning, porcelain slabs stay looking fresh and require no sealing or specialist treatments.

Large-format porcelain slabs can’t be treated like standard tiles. Their size, weight, and rigidity mean they require specialist equipment and experienced handling to cut, move, and fit safely. While some skilled tilers may attempt the work, it’s always best to choose an installer who regularly works with large-format porcelain. This ensures a precise finish and reduces the risk of costly mistakes.

This expertise is especially critical for projects that demand accuracy — such as book-matched patterns, seamless wall cladding, or ultra-tight joints where even the smallest misalignment becomes noticeable. Professional installers know how to manage weight distribution, plan support, and handle sheets without damage, ensuring every slab is set securely.

At Stoneworld, we prepare sheets in advance using advanced water-jet cutting and specialist porcelain machinery. Mitred edges, socket cut-outs, and apertures are completed in our workshop so the slabs arrive ready to install. By reducing the need for on-site cutting, the installation process becomes cleaner, quicker, and far more reliable.

Yes, although “large format” typically refers to porcelain slabs measuring up to 3000 × 1200 mm, manufacturers can often produce bespoke dimensions to suit particular projects. The main limitations are handling and substrate support.

Very large or tall panels may require additional structural backing or support framing, especially when installed vertically. Your installer or designer should assess whether the wall or structure can safely bear the weight. At Stoneworld, our precision workshop cutting ensures that even oversized panels arrive ready to fit, with any necessary reinforcements planned.

Large-format porcelain sheets require the right supply, preparation, and handling to achieve the best results. At Stoneworld, we support you through every stage — from selecting the ideal format to precision fabrication and safe delivery. With advanced cutting equipment and expert advice, we ensure your project runs efficiently and achieves the seamless finish you’re aiming for.
