Large tiles: fewer joins, a calmer surface and some trade-offs to weigh
A large tile changes the scale of a room. With fewer joints, the surface reads as one continuous plane, and there is less grout to clean. This collection holds the larger formats in the TBS range: 300 x 600mm and 450 x 900mm rectangles, 600 x 600mm squares, 600 x 1200mm rectangles and a pair of 22.5 x 900mm plank formats, mostly in porcelain, in stone, travertine, terrazzo and concrete looks.
The sections below cover why people choose large formats, how they behave in small bathrooms and on shower floors, what the slip and Area lines print, and where the trade-offs lie. For the whole range of floors, see the floor tiles collection, and for rooms, the bathroom tiles collection.
Why people choose large formats
Suppliers give consistent reasons. A national retailer says large format tiles change the scale of a room so the design shows in its best form, with less interruption from grout lines and less cleaning to worry about. A Sydney supplier describes a flowing, open look with fewer grout joints and easy maintenance, and says that is why people are embracing big tiles. It also says large formats were once mainly used in commercial settings, such as lobbies and entryways, and are now common in homes.
A US bathroom supplier makes the same point from the other direction: fewer grout lines reduce visual clutter, so the surface reads as one continuous plane and the room feels larger, especially with light, low-contrast tile and grout. A US flooring guide agrees that large-format tiles give a sleek, contemporary look with fewer grout lines and a more continuous appearance.
What counts as large in this collection
The Sydney supplier says sizes are moving upwards from the norm of 600 x 600mm. They now reach 750, 800 and 900mm squares and 600 x 1200mm and larger rectangles, with panels of up to 1620 x 3200mm at the top. It calls 600 x 1200mm the standout choice for consumers. The tiles in this collection run up to 600 x 1200mm, with the Dimensions lines showing 300 x 600mm, 450 x 900mm, 600 x 600mm and 600 x 1200mm as the main formats.
Most of the range sits at 600 x 600mm and 300 x 600mm, with a smaller group at 600 x 1200mm. For the size handles on their own, see the 600x600mm tiles collection and the 600x1200mm tiles collection.
What counts as large format
Definitions vary. A US stone and tile supplier says large format is a design category defined purely by scale, using the same manufacturing as standard tile, and counts any tile 15 inches (roughly 380mm) or longer on any side. A second US supplier uses the same threshold and says anything over 32 x 32 inches is extra big. By that measure the 300 x 600mm tiles in this collection qualify, because one side is 600mm, and the 600 x 1200mm tiles sit in the middle of the large-format range.
The second supplier adds a warning about scale: a very large tile in a small bathroom can dominate it, and the choice should follow the room. That sits comfortably with the retailer's view above, since both say the tile has to suit the space, not the other way around.
Why porcelain is the usual material
A US supplier explains why large-format floor tile is mostly porcelain. Porcelain is dense and strong, so manufacturers can produce larger tiles that stay flat. Ceramic is less dense and prone to warping in the kiln when made in larger sizes, so large-format ceramic is generally used for walls and not floors. That matches this collection: porcelain makes up most of it, and the one ceramic range, White Gemma in 300 x 600mm, is the smaller format.
Rectified or non-rectified
Edge matters more on a large tile than a small one. A US supplier says large-format porcelain is fired and cut to exact size, so the edges are straight, which allows narrow joints. It adds that non-rectified versions show their firing inconsistencies more on a large scale, which means wider joints to cover them, and that this undercuts the aesthetic goal. The advice is to check the rectification before buying, and the Edge line in this collection prints it.
Large tiles in a small bathroom
A common worry is that large tiles overwhelm a small room. A retailer answers it directly: tile size should not be determined by bathroom size, and a small bathroom can look striking with large format tiles. A US supplier of bathroom tile says a 12 x 24 inch tile is the most versatile choice. It is large enough to cut down grout lines and small enough to limit waste and awkward cuts. A 24 x 24 inch tile, it adds, gives a calmer, modern feel. Both can go on floors and walls, with the layout planned to avoid thin slivers at the edges.
A US flooring guide adds a balance: a tiny bathroom can feel crowded with large-format tiles, while large bathrooms can look disjointed with very small mosaics, and the right size balances the look with the needs of each zone. It also notes that small rooms benefit from medium to large tiles for fewer grout lines, though very small bathrooms sometimes suit medium tiles better to avoid awkward large cuts. In this collection, 300 x 600mm is the smaller option, and 600 x 600mm and 600 x 1200mm are the larger ones.
Shower floors are the exception
The one place large tiles do not suit is the sloped shower floor. A US flooring guide says shower floors perform best with smaller tiles, from mosaics to small squares, because they allow the surface to slope properly to the drain, and because the extra grout lines provide traction. It describes small tiles as well suited to curved surfaces, shower pans and accent details, and the preferred choice for shower floors and niches.
So a bathroom with a large-format floor and walls usually pairs them with a mosaic in the shower. The mosaic tiles collection covers the small formats. The guide also suggests mixing sizes, such as a large-format floor tile with a smaller subway tile on the walls, or a mosaic band to break up a large field of tile, with a consistent grout colour to hold the design together. The subway tiles collection holds the subway shapes.
Vertical or horizontal
Orientation changes how a room reads. The US flooring guide says laying rectangular tiles vertically can make ceilings feel higher, and laying them horizontally can widen a narrow bathroom. Another supplier suggests that for plank-size timber-look tiles, offsetting the tiles by about 150 to 200mm gives a natural-looking finish. The collection includes the 450 x 900mm and 22.5 x 900mm plank formats, which suit that kind of layout.
For a shape with more movement than a straight lay, the herringbone tiles collection covers the zigzag.
Rectified edges and joints
The Edge lines in this collection print Rectified for nearly all tiles, with a handful of non-rectified exceptions. A US supplier says rectified tile lets you run thin joints, which is what you want for a continuous look in a small bathroom, and the Valerie listings print a recommended gap of 1.5mm to 3mm. A tiler can confirm the joint for the tile in hand, since the right gap depends on the tile and the edge.
Because the surface is so continuous, grout colour matters. Matching the grout to the tile hides the joints, and a contrast makes the grid visible. For a continuous surface, choose a tonal grout.
Substrate and installation: ask the tiler
Suppliers agree that large tiles ask more of the installation. A US flooring guide says they need a flat, well-prepared substrate and professional installation to prevent lippage, which is where one edge sits higher than its neighbour. A Sydney supplier says large porcelain panels need very specific handling and installation techniques. A retailer says large format tiles should not crack when installed correctly and not subject to settlement issues.
The practical step is to involve the tiler early. Ask about the state of the floor or wall, whether it needs preparation, and how the tiler plans to handle and fix the size you choose. This body does not set out installation methods, which depend on the tile and the substrate.
Repairs and layout planning
Suppliers name two more points to weigh. Replacing a cracked large tile is significantly harder than replacing a small one, a US supplier says, because removing such a large piece increases the risk of damaging the surrounding tiles. And planning the layout matters more. It is worth mapping where each tile will fall before work begins, so that thin slivers are not left at the edges. The grout lines should also land where you want them, which you have less control over with a large tile.
A US supplier of porcelain adds that a large-format layout in a smaller bathroom generally works best when it stays simple, with few pattern changes, borders or visual breaks that shrink the space.
Slip lines on the large tile listings
The listings print a wide spread of slip lines. P4 and P5 are the largest groups, with P3 and some Not rated lines, and the wording varies. Some P3 pages say the risk is moderate and recommend the tile for indoor wet areas, including bathrooms, kitchens and laundries, and others describe P3 as moderate to high risk and suited to dry areas. P5 pages describe a very low slip risk suitable for outdoor use.
A US flooring guide notes that matte or textured finishes reduce slipperiness compared with glossier options, and says to verify slip ratings and local requirements for wet areas. The finishes in this collection are mostly matte, with a large group in grip, and smaller groups in 3D, lappato and polished. The floor tiles collection explains the P and R scales in detail.
Walls, floors and outdoors
The Application line says where each tile can go. Most print Walls and Floors, a smaller group prints Floors, and a few print Walls only. The Area line adds the setting: Indoors, Indoors (wet and dry areas), Indoors and covered outdoor areas, Indoors and Outdoors, and Outdoors. A Sydney supplier notes that matching indoor and outdoor floor tiles give continuity, and the collection has examples: the Avalon charcoal and greige external tiles print P5, and the Clio terrazzo in 300 x 600mm prints Indoors and Outdoors.
For the outdoor side, the outdoor tiles collection compares the full external range, and the wall tiles collection sorts the wall formats.
Stone, concrete, terrazzo and travertine looks
Large formats suit stone looks, since the larger surface shows more of the veining. The Sydney supplier says manufacturers use advanced technology to emulate natural stone, with Carrara, limestone, travertine, granite looks and finishes from polished to matt. In this collection, the Tundra stone look is described as delivering authentic quarried aesthetics, Casuarina is a modern take on natural stone, and Avalon has subtle vein movement. Myra limestone is described as a replication of a Turkish stone in white and cream, and Burleigh is for people who love natural stone and not the care.
Travertine looks include Tuscan and Valerie, and the Josie cross-cut travertine shows natural layers of stone. Terrazzo looks include Clio, Island and Southside. For these looks in more depth, see the travertine look tiles collection and the terrazzo look tiles collection.
Wear and maintenance
Most large tiles here print a wear line of 4, suitable for floors in normal use areas with a low risk of scratching, with a group at 3 for light traffic and a few at 5 for high-traffic and commercial areas. Wall-only tiles print Wall Category 0. The Maintenance lines print Easy to clean or Easy to clean and maintain, and many add that no sealing is required.
The cleaning advantage of large tiles is the grout. A US flooring guide says more grout lines mean more cleaning, so larger tiles suit rooms where lower maintenance matters. A retailer makes the same point: less interruption from grout lines means less cleaning to worry about.
Colour in the large format range
Neutrals dominate. Beige, grey and white are the three largest colour groups, with black, cream, greige, brown and ivory in smaller numbers. For colours across the store, see the beige tiles collection, the grey tiles collection and the white tiles collection.
Variation across a large floor
The Appearance lines show how much each tile varies, and on a large floor the variation is more visible, since each tile covers more area. Many listings print V2, slight variation, a good number print V3 for moderate variation, and a smaller group prints V1 for a uniform look. Some ranges, such as Valerie, are described as having multiple faces, so the pattern does not repeat obviously across the floor.
Why large tiles suit some rooms better
A US supplier lists the best homes for large-format porcelain as open floor plans, modern bathrooms and feature walls, and the best homes for standard tile as small spaces, shower floors and DIY projects. That matches the guidance above: large formats reward a room with space to show the surface and a simple layout, while small formats suit the slopes and details. Fewer grout lines also mean fewer junctions to clean, which the same supplier lists among the practical gains.
Ordering extra for cuts
Order more than the measured area. One tile supplier adds 10 percent for cuts and spares, and another recommends 10 to 15 percent, rising to 20 percent for large formats such as 600 x 1200mm and bigger. The Valerie listings give 15 percent. Rooms with more cuts need more again, so confirm the quantity with your builder or tiler before ordering.

Choosing a large tile
Start with the room and the surface. For a bathroom floor or wall, a 600 x 600mm or 600 x 1200mm tile gives the fewest joints, and a 300 x 600mm tile suits a very small room. For the shower floor, choose a mosaic. For any floor, read the slip line, the wear line and the Application line before the colour.
Talk to your tiler about the substrate before ordering, choose a tonal grout for a continuous surface, and order extra for cuts. The tiles collection sits above this one for the whole range.
