Onyx Effect Tiles

Shop our collection of onyx effect tiles. Onyx has been prized for centuries for its dramatic veining, rich depth and luminous finish. Made from durable porcelain and ceramic, these designs replicate the swirling beauty of natural onyx while giving you all the practical perks. Whether you’re tiling a bathroom wall, a kitchen or even a statement floor, you’ll get the same luxurious look.

Colour is where onyx effect tiles really shine. Choose soft pearl, cream or white shades for a clean feel. Add warmth with a pink tone or go bold with blue or emerald green. Each one of these marble effect tiles captures the natural variation of onyx, with flowing veining and unique detail that brings depth and movement to every surface.

There’s no shortage of choice when it comes to styles, sizes and finishes. Large format tiles create an expansive effect, while smaller options keep things versatile. Polished tiles give you high end gloss, matt designs add understated elegance and satin finishes balance the two. For walls that deserve extra texture, our fluted onyx effect tiles offer a contemporary twist.

Less grouting.

Loved the tiles, nice and big meaning that you have less grout joints. Porcelain tiles are really hard so make sure you have the appropriate drill bits to make the holes.

FAQ's

Onyx effect tiles give you the veining and glow of natural marble without the sealing, staining and eye-watering price tag. Here’s how to choose, fit and style them like a professional.

What are onyx effect tiles?

Onyx effect tiles are porcelain or ceramic tiles designed to mirror the look of natural onyx. They feature layered veining and high gloss finishes. Available in polished, matt and satin finishes, plus textured reeded and fluted styles for added interest.

Unlike real onyx, they are tougher, more water-resistant and less porous. It’s also easier to match patterns. Plus, and perhaps most importantly, they are far more budget-friendly.

Are they durable?

Yes, onyx effect tiles are built to last, particularly if they are porcelain tiles. They’re scratch and stain-resistant, easy to clean and handle moisture well. Add felt pads under furniture and avoid scouring pads to keep floors looking sharp.

Are they slippery?

Polished tiles can feel slick when wet, which makes them a great choice for walls or dry floors. For floors in showers or wet rooms, pick a matt or slip-rated porcelain (look for R10 or higher).

Do they need sealing?

No, the tile doesn’t. Just seal the grout lines to keep them clean and easy to wipe down.

Where can I use onyx effect tiles?

Onyx effect tiles work in a variety of rooms or spaces, such as:

Bathrooms and showers: Ideal for walls, floors and wet rooms.
Kitchens: Great for splashbacks, feature walls or statement floors.
Living areas and hallways: Use large formats for a continuous feel.

What sizes and layouts work best?

Large format tiles (e.g. 600 by 1200mm or 1000 by 1000mm) show off the incredible veining inherent to onyx effect tiles and minimise grout lines. Mid-size tiles (e.g. 300 by 600mm or 600 by 600mm) are good for smaller spaces. Textured or fluted tiles are perfect for niches, splashbacks and feature strips.
