Rossato Onyx Effect Matt Porcelain Wall & Floor Tile: Colours, Sizes and Full Specification Guide

The Rossato onyx effect matt porcelain wall and floor tile is a rectified, glazed porcelain tile that reproduces the layered banding of natural onyx across a non-reflective matt surface. The range runs in four colourways, Crema, Nero, Silver and Bianco, and three formats, 30x60cm, 60x60cm and 60x120cm, giving twelve variants that share one visual language. Every variant is rated for both walls and floors, which means a single tile can carry a whole room from shower wall to hallway floor without a change in tone.

This guide covers what the tile is, how the four colours differ, which format suits which room, what the matt finish and rectified edges actually change in practice, how many tiles you need per square metre, and how the range should be fitted, grouted and maintained.

What Is the Rossato Onyx Effect Matt Porcelain Wall & Floor Tile?

The Rossato onyx effect matt porcelain tile is a vitrified porcelain tile with a digitally printed onyx graphic and a matt glaze, produced with rectified edges for narrow, uniform grout joints.

Three attributes define it and separate it from the wider tile market:

It is porcelain, not ceramic. Porcelain is pressed from finer clays and fired at higher temperatures than standard ceramic, producing a denser body with a water absorption rate at or below 0.5 percent. That density is what makes the same tile usable on a shower floor and a kitchen floor rather than walls only.

The surface is matt, not polished. A matt glaze scatters light instead of reflecting it. The onyx veining stays readable under bright lighting, fingerprints and water spots are far less visible, and the surface offers more grip underfoot than a polished equivalent.

The edges are rectified. After firing, each tile is mechanically cut to an exact dimension with square edges, so tiles butt together with minimal joints and no size drift across a large run.

The range is supplied as a wall and floor tile, so it is not restricted by application. That is the practical difference between the Rossato range and most decorative onyx effect wall tiles, which are glaze-only ceramics rated for vertical surfaces alone.

What Makes Onyx Effect Porcelain Different From Natural Onyx?

Onyx effect porcelain reproduces the appearance of natural onyx while avoiding the porosity, fragility and maintenance burden of the real stone.

Natural onyx is a banded variety of chalcedony, a microcrystalline form of quartz. Its beauty comes from thin parallel layers of mineral deposit that give it depth and, in thin slabs, partial translucency. Those same layers are its weakness. Natural onyx is soft, porous, prone to acid etching from ordinary bathroom and kitchen products, and it needs sealing and resealing throughout its life. Many natural onyx slabs need mesh backing simply to survive transport and cutting.

Onyx effect porcelain takes the visual result and rebuilds it on a body that behaves nothing like stone:

• It does not need sealing. The glaze layer is fired glass. There is no open pore structure for water or staining agents to enter.

• It resists acids. Limescale removers, citrus cleaners and soap residue do not etch a glazed porcelain surface the way they etch natural onyx.

• It is dimensionally consistent. Rectified porcelain arrives at a predictable size with a predictable pattern set, which natural stone never does.

• It is dramatically harder wearing. Porcelain handles foot traffic that would dull and scratch a soft banded stone within months.

The trade-off is honest and worth stating: natural onyx is genuinely translucent and can be backlit. Porcelain is opaque. If the design brief specifically calls for a backlit stone panel, porcelain is not the answer. For every other application, including bathrooms, kitchens, hallways, living spaces and feature walls, onyx effect porcelain delivers the look with none of the fragility.

Which Rossato Colourway Suits Your Space?

The four Rossato colourways sit on a single tonal ladder, from warm and light through to cool and dark, with vein contrast increasing as the base tone deepens.

 

Rossato Crema: Warm Cream With Soft Golden Movement

Rossato Crema carries a warm cream base with soft golden and honey-toned banding running through it.

The vein contrast is the lowest in the range, which makes Crema the most forgiving colourway to work with. It reads as a calm textured surface rather than a statement pattern, so it can cover a full room without becoming visually loud. The warm undertone reflects light softly, making it a strong choice for rooms with limited natural light or north-facing windows.

Best-fit rooms: full bathroom schemes, family bathrooms, open-plan kitchen floors, hallways. Pairs with: brushed brass, antique gold, warm oak, cream and sand grout, matt white sanitaryware.

Rossato Bianco: Bright White With Fine Grey Veining

Rossato Bianco pairs a bright white base with fine cool grey veining.

Bianco is the brightest option in the range and the most effective at making a compact room feel larger. The fine vein structure keeps it from reading as flat white, so it avoids the clinical look that plain white tiles can produce. Because the base is light and the veining is delicate, Bianco also works as the field tile in a two-tile scheme, with a darker colourway used on one feature surface.

Best-fit rooms: small bathrooms, en-suites, cloakrooms, shower enclosures, kitchen splashback zones. Pairs with: chrome, polished nickel, matt black, pale grey grout, light timber vanities.

Rossato Silver: Cool Mid-Grey With Layered Banding

Rossato Silver sits on a cool mid-grey base with layered silver and charcoal banding.

Silver is the most architectural of the four. Grey holds its neutrality across changing light through the day, which makes it a reliable choice for large floor areas and open layouts where a warm tone might read differently from one end of the room to the other. The layered banding gives it more visible movement than Crema without the high contrast of Nero.

Best-fit rooms: hallway and entrance floors, open-plan living floors, contemporary bathroom floors, utility spaces. Pairs with: matt black, brushed steel, chrome, mid-grey grout, walnut and dark timber.

Rossato Nero: Deep Black With High-Contrast Veining

Rossato Nero uses a deep black base with sharp white and pale grey veining cutting across it.

Nero is the statement tile of the range and carries the highest vein contrast. That contrast is the reason it works best in defined zones rather than across an entire room. A single Nero wall behind a bath, a Nero shower enclosure, or a Nero splashback creates a focal point, while the remaining surfaces stay in a lighter colourway. In a small room, full Nero coverage will close the space down unless the lighting scheme is designed around it.

Best-fit rooms: feature walls, walk-in shower enclosures, kitchen splashbacks, cloakrooms where drama is intentional. Pairs with: brushed brass, antique gold, matt black, charcoal grout, warm ambient lighting.

Which Rossato Size Should You Choose: 30x60cm, 60x60cm or 60x120cm?

Format selection comes down to three variables: how large the surface is, how many grout joints you want to see, and how flat the substrate is.

30x60cm (300x600mm): Compact Rooms and Vertical Walls

Each 30x60cm tile covers 0.18 square metres.

This is the format for compact rooms, awkward layouts and vertical wall applications. The smaller footprint means fewer awkward cuts around windows, niches, pipe boxings and shower trays, and the tile is light enough to fit single-handed on a wall. Laid vertically in a stacked or offset pattern, 30x60cm draws the eye upward and adds perceived ceiling height in a low room.

Joint density is the highest of the three formats, so grout colour choice matters most here. Handling is the easiest, which makes 30x60cm the practical choice for a first-time tiling project.

60x60cm (600x600mm): The Balanced All-Round Format

Each 60x60cm tile covers 0.36 square metres.

The square format is the most versatile of the three. It suits medium and large floors, carries walls without dominating them, and its symmetry means a straight lay always squares cleanly to the room. Because the tile is square, it also avoids the directional bias that rectangular formats introduce, which is useful in rooms that are close to square themselves.

Joint density sits in the middle. Substrate demands are moderate. If a single format has to cover both floor and wall in a coordinated scheme, 60x60cm is usually the answer.

60x120cm (600x1200mm): Large Format Seamless Surfaces

Each 60x120cm tile covers 0.72 square metres.

Large format is where onyx effect porcelain shows its full potential. A single 60x120cm tile carries a long, uninterrupted run of veining, so the surface reads as continuous stone rather than a grid of repeated pieces. Grout joints drop to a minimum, which is exactly what a feature wall or a seamless floor needs.

The trade-off is preparation. Large format is unforgiving of an uneven substrate, needs a full solid adhesive bed, and generally calls for levelling clips to control lippage. It is also heavy to handle and needs two people on a wall. For a feature wall, a shower enclosure, an open-plan floor or a large bathroom, the result justifies the extra care.

How Face Variation Changes What You See in Each Format

Face variation is the number of distinct printed designs in a range, and it is the attribute that decides whether a tiled surface looks like real stone or like a repeating pattern.

The Rossato range carries a different face count in each format:

This matters when you plan a layout. With eleven faces in 30x60cm, you can tile an entire bathroom wall without ever placing two identical tiles next to each other. With four faces in 60x120cm, the sensible approach is to open several boxes at once, dry lay a run before fixing, and deliberately separate matching faces so no two identical tiles sit adjacent or directly above one another.

Almost nobody plans for this, and it is the single most common reason a stone effect installation ends up looking printed rather than natural.

Why Does the Matt Finish Matter?

The matt finish changes three things: how the veining reads, how much maintenance the surface demands, and how it behaves underfoot when wet.

A polished onyx effect tile reflects light back at the viewer. In a bright bathroom this produces glare across the surface, and glare flattens the veining. A matt glaze scatters that light instead, so the onyx banding stays legible from every angle and in every lighting condition. On a large feature wall the difference is significant, because a polished surface will show a bright hotspot wherever a light source sits, while a matt surface distributes it.

Maintenance is the second difference. Polished surfaces show water spots, soap residue and fingerprints clearly, because any deposit interrupts a mirror-flat reflection. A matt surface has no mirror to interrupt, so day-to-day marks are far less visible between cleans. In a family bathroom or a busy kitchen, this is the practical argument for matt over polished.

Grip is the third. A polished glaze becomes noticeably slick when wet. A matt glaze holds more surface texture and performs better in wet zones, which is why matt is the standard recommendation for shower floors, wet rooms and bathroom floors. Slip performance is measured formally, so for a shower floor or a wet room always check the published slip rating on the product page and match it to the application rather than relying on finish type alone. Our non-slip bathroom floor tiles guide explains how the rating systems work and which values suit which zone.

If matt is the direction you want across a whole scheme, the wider matt tiles collection covers the same finish in other colours and effects.

What Do Rectified Edges Change About the Finished Result?

Rectified edges allow narrow, perfectly uniform grout joints, which is what makes a large format installation read as a continuous surface.

Standard pressed tiles come out of the kiln with slight dimensional variation, because clay shrinks unevenly during firing. Installers absorb that variation in the grout joint, which is why non-rectified tiles typically need joints of 3mm or more. Rectified tiles are cut to an exact size after firing, so every tile in the box matches every other tile to a tight tolerance.

Three things follow from that:

Joints get narrower. A rectified tile can be fitted with joints of around 2mm on walls and around 3mm on floors, instead of the wider joints a non-rectified tile requires.

The eye stops reading a grid. Narrow joints in a matching grout colour let the veining carry across tile boundaries, so a wall of 60x120cm Rossato reads as one stone surface rather than a set of panels.

Setting out becomes less forgiving. Precision cuts both ways. With a 2mm joint there is no room to absorb a substrate that runs out of square or a tile that is fitted slightly proud. Rectified tiles reward careful setting out and punish rushed work.

Grout joints should never be eliminated entirely. A joint absorbs thermal movement, building movement and substrate movement. Butt-jointing rectified tiles with no gap will lead to edge chipping and grout failure regardless of how precise the tiles are.

Full Specification and Complete Range Matrix

The table below sets out the shared specification across the whole Rossato onyx effect matt porcelain range.

The Complete Rossato Range: All Twelve Variants

Because all twelve variants share one graphic language and one finish, colourways and formats can be mixed within a single scheme without a visual clash. A Nero 60x120cm feature wall with a Crema 60x60cm floor works because both tiles come from the same design family.

How Many Rossato Tiles Do You Need Per Square Metre?

Coverage is fixed by format, so the tile count per square metre is straightforward.

Adding the Right Wastage Allowance

Never order the exact measured area. Cuts, breakages and pattern matching all consume tile.

A worked example. A bathroom floor measuring 2.4m by 1.8m is 4.32 square metres. In 60x60cm that is 4.32 divided by 0.36, which is 12 tiles exactly. Add 12 percent for a room with a shower tray and boxing, and the order becomes 14 tiles, or 5.04 square metres.

Always round up to whole boxes and order every box in the same transaction so the entire order comes from one production batch. Keeping a small surplus after installation is deliberate, not wasteful. If a tile cracks in three years, a matching replacement from the original batch is the only way to make the repair invisible.

How Should Rossato Onyx Effect Tiles Be Installed?

Rossato tiles are installed using standard porcelain tiling methods, with extra attention to substrate flatness and adhesive coverage in the 60x120cm format.

Substrate Preparation and Flatness Tolerance

The substrate must be sound, clean, dry, dust-free and structurally stable before any adhesive is applied.

Flatness is the variable that decides whether a large format installation succeeds. As tile size increases, the substrate tolerance tightens, because a long rigid tile cannot follow a curve or a hollow. For 60x120cm, the working target is a deviation of no more than around 3mm across a 2m straight edge. Anywhere the substrate falls outside that, use a levelling compound on floors or a skim and re-float on walls before tiling. Attempting to correct an uneven substrate with adhesive thickness alone is the most common cause of lippage, hollow spots and cracked tiles.

In wet areas, apply a tanking or waterproofing system to the substrate before tiling. Tiles and grout are water resistant, but the assembly behind them is not. This applies to shower enclosures, wet rooms and any wall that takes direct spray.

Choosing the Right Adhesive

Use a flexible, cement-based adhesive of at least C2TE S1 classification. The C2 rating covers bond strength for dense low-absorption bodies, the T covers slip resistance so wall tiles do not slide during setting, the E covers extended open time, and the S1 covers deformability for movement.

Coverage is critical. Because porcelain absorbs almost no water, the bond is mechanical rather than absorptive, and voids behind the tile become weak points that crack under load. Aim for full solid bed coverage, and back-butter every 60x120cm tile in addition to notching the substrate. In wet areas and on all floors, full coverage is not optional.

Use a notch size appropriate to the format. Larger tiles need a deeper notch to deliver enough adhesive to close the gap and achieve solid contact.

Controlling Lippage on Large Format

Lippage is the height difference between the edges of two adjacent tiles, and it is the defect most visible on a matt surface under raking light.

Use levelling clips and wedges across the whole area for 60x120cm, and on any floor installation in 60x60cm where the substrate is not perfectly flat. Fit them on every joint, not just the long edges. A brick bond layout with a large offset dramatically increases lippage risk, because the centre of one tile meets the edge of its neighbour where any slight bowing in the tile body is at its maximum. If you want a brick bond with 60x120cm, keep the offset to around one third rather than one half.

Cutting and Drilling Dense Porcelain

Porcelain is significantly harder than ceramic and needs the right tooling.

For straight cuts, use a wet cutting bench saw with a continuous rim diamond blade, feeding the tile slowly and letting the blade do the work. A manual score-and-snap cutter can handle straight cuts in thinner formats but struggles with 60x120cm. For circular cuts around pipes and tap tails, use a diamond core bit at low speed with water cooling, starting at an angle to establish the cut line before bringing the bit square. Never use a masonry bit, and never drill dry at high speed.

Always cut face up and keep the tile fully supported to prevent the offcut snapping away and chipping the glazed edge.

Shade Batches and Dry Laying

Order the entire quantity in one go so all boxes come from a single production batch, and check the batch or shade code printed on each box before starting.

Before fixing anything, open at least four boxes and dry lay a section of the run on the floor. This lets you see how the individual faces distribute and lets you deliberately separate matching designs. Then work from all open boxes simultaneously as you fix rather than emptying one box at a time, which is how identical faces end up clustered together.

Which Grout Colour Works Best With Each Rossato Colourway?

Grout colour determines whether the tiled surface reads as continuous stone or as a defined grid, and the correct choice differs for each Rossato colourway.

The general rule for onyx effect porcelain is tonal matching. Match the grout to the base tone of the tile, not to the veining. Matching the veining makes the joints stand out unpredictably, because the veining moves and the joint does not.

Use a flexible cement-based grout suited to the joint width, and choose a grout rated for wet areas in showers and wet rooms. In heavy-use zones such as a shower floor or a kitchen splashback, an epoxy or a stain-resistant polymer grout resists discolouration far better than standard cement grout over time.

If the tile colour is the starting point for the whole scheme rather than the finish, browse the cream tiles collection for warm neutral coordination, the beige bathroom tiles range for softer tonal pairings, or the grey bathroom tiles range to build around Silver. Our beige bathroom tile ideas guide shows how warm neutrals behave across a complete room.

Which Layout Patterns Suit Onyx Effect Veining?

Layout choice interacts directly with veining, because a pattern that breaks up the vein flow works against the entire point of a stone effect tile.

Straight lay (stack bond). Tiles align in a clean grid with joints running continuously in both directions. This is the correct default for onyx effect porcelain in every format. It keeps the veining flowing across tile boundaries and produces the most seamless result, particularly in 60x120cm on a feature wall.

Brick bond (offset). Each row shifts relative to the one below. A one third offset works well with 30x60cm and adds informal movement without disrupting the veining badly. Keep the offset modest with 60x120cm, because a half offset both increases lippage risk and cuts the vein flow at the point of maximum visual attention.

Vertical stack. Tiles run vertically in aligned columns. This is the most effective way to add perceived height to a low room, and it suits 30x60cm on a shower wall particularly well. It also flatters a high-contrast colourway such as Nero, because the vein direction runs with the eye rather than across it.

Herringbone. The interlocking diagonal arrangement creates strong directional energy and works with the 30x60cm format. Be aware that herringbone deliberately fragments the vein flow, so it suits Crema and Bianco, where the veining is subtle, far better than Nero, where the high contrast will produce a busy result. Wastage climbs to 15 to 20 percent. Our patterned bathroom floor tile guide covers layout planning for directional patterns in detail.

Half tiling. Running Rossato to a datum height of around 1.1m to 1.2m with painted or panelled wall above is a cost-effective way to use a large format tile in a smaller room. The half tiled bathroom ideas guide sets out the height calculations and transition detailing.

If you want to combine a smooth matt onyx effect with a tactile surface elsewhere in the room, the textured bathroom tiles guide covers ribbed, fluted and relief finishes that pair well with flat stone effects.

How Do You Clean and Maintain Matt Onyx Effect Porcelain?

Matt onyx effect porcelain needs no sealing and no specialist treatment, but it does respond better to a different cleaning routine than a polished surface.

Routine cleaning. Sweep or vacuum floors to lift grit before mopping, since grit is abrasive and dragging it across a surface does more damage than any cleaning product. Wash with warm water and a pH-neutral tile cleaner. Change the water frequently, because reusing dirty water simply redistributes residue across the surface.

The one habit that matters most. Matt surfaces hold cleaning residue more readily than polished surfaces, because the micro-texture that gives them grip also gives detergent somewhere to sit. A dull, patchy film on a matt tile is almost always product build-up, not damage. Rinse with clean water after washing and dry with a microfiber cloth, and the problem never appears.

What to avoid. Do not use waxes, polishes or oil-based floor treatments, which leave a film that attracts dirt. Do not use bleach or strong acids routinely, which attack grout even where they do not affect the glaze. Do not use abrasive powders or scouring pads on the glaze.

Grout care. The grout is almost always what discolours, not the tile. Clean grout lines with a soft brush and a dedicated grout cleaner as needed, and consider sealing cement-based grout in shower zones.

Limescale in hard water areas. Use a limescale remover formulated for tiles, apply it to the affected area only, leave it for the stated dwell time rather than scrubbing, then rinse thoroughly. Never leave an acidic product sitting on grout.

Are Rossato Tiles Compatible With Underfloor Heating?

Yes. Porcelain is one of the best floor coverings for underfloor heating, and the Rossato range is suitable for use over both electric mat and wet pipe systems.

Porcelain's density gives it high thermal conductivity, so heat transfers into the room quickly rather than being held back by the floor covering. It also has high thermal mass, meaning the floor retains warmth after the system cycles off.

Three points govern a successful installation:

Use the right adhesive. A flexible C2TE S1 adhesive accommodates the thermal expansion and contraction cycles that a heated floor goes through. A rigid adhesive will eventually fail at the bond line.

Commission the system correctly. Allow the screed or levelling compound to cure fully before running the heating. Once tiling is complete, allow the adhesive and grout to cure fully, then bring the system up to temperature gradually over several days rather than switching to full output immediately.

Include movement joints. A heated floor moves. Perimeter movement joints and intermediate joints in larger areas prevent that movement from being transferred into the tiles as stress.

Large format tiles perform particularly well over underfloor heating, because fewer grout joints mean fewer interruptions in the conductive surface. The 60x120cm format is the strongest performer in the range for a heated floor. For more options rated for heated floors, browse the wider bathroom porcelain tiles range.

How Does Rossato Compare With Natural Onyx and Polished Onyx Effect Porcelain?

The table below sets out the three options against the attributes that actually decide a specification.

The short version: choose matt onyx effect porcelain when the surface has to perform daily; choose polished onyx effect porcelain when a light-reflecting feature wall in a dry zone is the goal; choose natural onyx only when genuine translucency is the design requirement and the budget covers ongoing maintenance.

If the choice is between onyx effect and other stone effects, the marble effect bathroom tiles range offers more linear, structured veining while onyx effect gives softer layered banding. For floors specifically, the marble effect floor tiles collection covers the equivalent options in floor-rated formats. For a completely different texture with the same neutral palette, the terrazzo bathroom tiles guide covers aggregate-based alternatives.

How to Build a Complete Scheme Around the Rossato Range

Because every Rossato variant shares one design language, the range is built for coordinated schemes rather than single-surface use.

The single-tile scheme. Use one colourway across floor and walls in a single format, or in two formats with the larger on the floor. Crema and Bianco carry this best, because their low vein contrast can cover a full room without fatigue. This produces the calmest, most expensive-looking result and is the approach to take in a small room.

The two-tile feature scheme. Use a light colourway across the field surfaces and a dark colourway on one feature surface. Bianco walls with a Nero shower enclosure, or Crema walls with a Nero feature wall behind the bath, are the two strongest combinations in the range. Keep the grout tonal to each tile rather than matching one grout across both.

The split-format scheme. Use 60x120cm on the largest uninterrupted surface, typically a feature wall or the main floor, and 30x60cm on the surfaces with the most cuts, typically around windows, niches and boxings. This keeps the seamless look where it is visible and keeps the fitting practical where it matters.

Frequently Asked Questions About Rossato Onyx Effect Matt Porcelain Tiles

Are Rossato tiles suitable for bathroom floors?

Yes. The Rossato range is rated for both walls and floors, and porcelain's water absorption of 0.5 percent or below makes it appropriate for bathroom floors, showers and wet rooms. For shower floors specifically, check the published slip rating on the product page and match it to the application.

Do onyx effect porcelain tiles need sealing?

No. The glaze is a fired glass layer with no open pore structure, so there is nothing for a sealer to penetrate. Cement-based grout in wet zones can benefit from sealing, but the tile itself never does.

Are matt tiles slippery when wet?

Matt tiles give better wet grip than polished tiles of the same body, because the surface texture that diffuses light also provides mechanical grip. Slip performance is still measured formally rather than assumed from finish type, so check the rating before specifying any tile for a shower floor.

What is the difference between Rossato Crema and Rossato Bianco?

Crema has a warm cream base with soft golden banding and low vein contrast. Bianco has a bright white base with fine cool grey veining. Crema suits warm schemes with brass and oak; Bianco suits cool schemes with chrome and matt black, and does more to brighten a compact room.

Which Rossato size is best for a small bathroom?

30x60cm is the most practical, because it needs fewer awkward cuts and can be laid vertically to add perceived height. 60x60cm also works well if the room is close to square. 60x120cm can be used in a small bathroom, but only on a single uninterrupted surface such as a shower wall.

How many 60x120cm tiles are there in a square metre?

Each 60x120cm tile covers 0.72 square metres, so one square metre needs 1.39 tiles. For 60x60cm the figure is 2.78 tiles per square metre, and for 30x60cm it is 5.56 tiles per square metre.

How much extra should I order for wastage?

Add 10 percent for a straight lay in a simple rectangular room, 12 to 15 percent for a room with alcoves, niches or a shower tray, and 15 to 20 percent for diagonal or herringbone layouts.

What adhesive should be used for the 60x120cm format?

A flexible cement-based adhesive of at least C2TE S1 classification, applied to achieve full solid bed coverage, with each tile back-buttered in addition to notching the substrate.

What does face variation mean and why does it differ across the sizes?

Face variation is the number of distinct printed designs in a format. The Rossato range carries 11 faces in 30x60cm, 8 in 60x60cm and 4 in 60x120cm. More faces means repeats are harder to spot. Because a 60x120cm tile covers four times the area of a 30x60cm tile, four faces still span a large surface before any design repeats.

Can Rossato tiles be used over underfloor heating?

Yes. Porcelain conducts and retains heat well, making it one of the best surfaces for heated floors. Use a flexible C2TE S1 adhesive, allow adhesive and grout to cure fully, and bring the system up to temperature gradually.

Can different Rossato colourways be mixed in one room?

Yes. All twelve variants share the same graphic language and matt finish, so colourways and formats combine without clashing. The most effective approach is a light colourway across the field surfaces with a darker colourway on one feature surface.

Are these tiles frost resistant?

Yes. The vitrified porcelain body has a water absorption rate at or below 0.5 percent, which is the threshold that gives porcelain its frost resistance.
