The attraction of onyx is its depth.

Natural onyx is prized for the way its layers, veins and translucent-looking mineral formations create movement across the stone. Onyx Metro takes inspiration from that visual language, giving the individual tiles enough variation to prevent a large wall from feeling flat.

What makes this particularly interesting in a metro format is the contrast between organic stone movement and geometric repetition.

The tile arrangement establishes order. The surface introduces unpredictability.

Three Colours, Three Very Different Interiors

Pink

Pink is undoubtedly the most expressive choice.

Rather than treating it as a pastel accent, I'd approach it as a warm stone colour. Pairing it with cream, natural timber and brushed brass creates an exceptionally soft bathroom palette, while darker cabinetry or aged metalwork can give it a much more sophisticated edge.

The inspiration image demonstrates why Pink Onyx works particularly well in bathrooms: the combination of warm stone tones, white sanitaryware and brass creates an almost spa-like atmosphere.

Green

Green gives Onyx a much more grounded, botanical character.

Natural oak, walnut, stone and brass all work beautifully alongside it. If you're looking for a bathroom that feels immersive rather than simply colourful, Green Onyx can work particularly well across a complete vanity or shower wall.

It also provides an interesting alternative to the more obviously "green tile" aesthetic because the marble movement breaks up the colour.

Grey

Grey is the most understated option and probably the easiest to integrate into an existing scheme.

The stone-inspired movement prevents it from feeling like a basic grey metro, while the neutral base allows considerably more freedom with cabinetry, brassware and flooring.

It's particularly useful when you want the luxury associated with marble without introducing another strong colour into the room.

Let the Marble Effect Lead

Onyx is already doing quite a lot visually, so I'd resist the temptation to introduce too many competing patterns.

If you're using Onyx across a vanity wall, for example, consider keeping the mirror relatively simple and allowing the tile to provide the artwork.

Likewise, if you're using it in a kitchen, a quieter worktop can actually make the marble effect appear more convincing and luxurious.

This doesn't mean the rest of the room has to be plain. Natural timber, brushed brass, textured fabrics and simple stone surfaces all complement the collection beautifully. The important distinction is between texture and competing pattern.

You want materials that support the movement in the tile rather than fight it.

The Metro Format Makes It More Versatile

One of the advantages of Onyx being presented in a metro format is that you aren't restricted to using it as a conventional marble feature wall.

A classic brick bond allows the marble movement to distribute naturally across the wall.

A stacked arrangement gives the collection a cleaner, more contemporary character, allowing the stone effect to become more dominant.

Vertical installation can emphasise height, particularly in shower enclosures or behind a vanity, while smaller areas such as niches can use the tile as a concentrated decorative detail.

This is where metro tiles are particularly useful: the same surface can look traditional or contemporary simply through the laying pattern.

Where I'd Use Onyx

Onyx is particularly suited to spaces where you want the wall itself to create atmosphere.

Bathrooms

Probably the natural home for the collection. A full vanity wall or shower enclosure allows the marble movement to become immersive, particularly when paired with warm lighting.

Cloakrooms

This is where I'd be more adventurous with Pink or Green. A smaller room can carry a stronger surface because there are fewer competing materials.

Kitchen Splashbacks

Grey or Green can work beautifully behind a kitchen worktop, particularly when the cabinetry is relatively restrained.

Feature Walls

You don't need to tile an entire room. A chimney breast, alcove or architectural recess can be enough to introduce the Onyx effect.

Onyx Compared With Metro Marble

These two collections are worth distinguishing because a customer could quite reasonably be deciding between them.

Onyx Metro is for someone attracted to organic, flowing stone movement and colour. Pink, Green and Grey allow the tile to become a strong part of the room's palette.

Metro Marble offers a broader family of marble-inspired metro styles, with different formats, profiles and gloss or matt finishes. It's better suited to someone who already knows the type of metro geometry or finish they want and wants to explore marble-inspired surfaces within it.

In simple terms:

Onyx = stone character first.

Metro Marble = metro design choice first.

That is a useful distinction for customers—and much more helpful than simply listing the two collections as similar marble-effect tiles.

I'd use Onyx when the customer wants their tile to be the thing people notice when they walk into the room. The marble movement gives it considerably more visual depth than a conventional coloured metro, but the familiar format keeps it approachable.

Pink is particularly effective when paired with warm stone and brass; Green has the strongest connection with natural materials; and Grey is the safest option if you're trying to introduce a marble effect without committing to a strong colour.

If you're considering Onyx for a large wall, I'd definitely recommend ordering a sample first. Marble-inspired surfaces can look much more complex when several tiles are viewed together than they appear in an individual product photograph.

Questions customers are likely to ask

What is an onyx-effect tile?

It's a tile designed to capture the layered movement, tonal depth and mineral character associated with natural onyx stone, while providing the consistency and practicality of a manufactured tile.

Is Onyx Metro a real stone tile?

No. It is an onyx-inspired tile rather than natural onyx. This gives you the visual character of the stone without the installation and maintenance considerations associated with using a natural slab or stone tile.

Which Onyx colour is easiest to style?

Grey is the most neutral and adaptable. Pink is the warmer, more decorative option, while Green creates the strongest connection with natural materials and can produce a particularly immersive interior.
