Onyx Beige: Which Finish and Tile Size Should You Choose?
Onyx Beige Porcelain: Matt or Polished, and Which Size Is Actually Right?
The Elegant Onyx Beige range comes in six near-identical-looking listings two finishes across three formats. Here’s what actually changes between them before you order.
Anyone who has scrolled through the Elegant Onyx Beige range has hit the same wall: six product listings, all showing the same warm beige veining, differing only in a size number and a word matt or polished buried in the title. Photographed under studio lighting, the six can look almost interchangeable. Laid across an actual floor, they behave quite differently from one another, and the wrong combination of size and finish is one of the more common regrets in a large-format porcelain order.
This guide exists to make that choice mechanical rather than aesthetic what the finish changes, what the format changes, and which combination of the two actually suits the room you’re tiling.
Matt or Polished: What The Finish Actually Changes
The surface pattern the beige veining inspired by natural onyx marble is identical across both finishes; only the surface sheen differs. That sounds like a minor distinction until it plays out in a real room.
Polished porcelain reflects far more ambient light, which is genuinely useful in a windowless bathroom or a north-facing hallway where every bit of brightness matters but a glossy surface is measurably more slippery when wet, and it also shows scuffs, footprints and drying water marks more readily than a matt equivalent. Matt is the safer default for any floor that will regularly get wet: bathrooms, wet rooms, boot rooms and kitchens. Polished earns its place on walls, in low-traffic living spaces, or on a floor in a room that stays reliably dry.
Format Comparison: 30x60cm vs 60x60cm vs 60x120cm
Size changes two things: how many grout lines interrupt the veined pattern, and how forgiving the tile is to lay in an awkward or irregular room. A 30x60cm tile is the most practical choice for a small bathroom or a room with several obstructions pipework, a WC, a shower tray because offcuts are cheaper and easier to plan around. A 60x60cm tile sits in the middle, close enough to square that it reads calmly in either a brick-bond or stacked grid layout. A 60x120cm tile gives the most continuous, least interrupted expanse of veining, but it needs a genuinely flat, well-prepared subfloor to sit correctly large-format porcelain telegraphs any dip or high point in the substrate far more obviously than a small tile does.
| Format & finish | Best used for | Grout joints | Subfloor demand |
|---|---|---|---|
| 30x60cm Matt | Small bathrooms, wet rooms, awkward layouts | More frequent | Low |
| 30x60cm Polished | Small feature walls, low-traffic areas | More frequent | Low |
| 60x60cm Matt | Kitchens, hallways, mid-size bathrooms | Moderate | Moderate |
| 60x60cm Polished | Living rooms, dry hallways | Moderate | Moderate |
| 60x120cm Matt | Open-plan floors, wet rooms wanting minimal joints | Minimal | High, needs a flat substrate |
| 60x120cm Polished | Statement walls, dry open-plan floors | Minimal | High, needs a flat substrate |

Slip Rating, Underfloor Heating and Wet Areas
The 30x60cm matt listing in this range carries an R9 slip rating, which is adequate for most domestic bathroom floors, though anyone tiling a level-access wet room or a floor that will see standing water regularly should confirm the rating of the specific format and finish before ordering, since polished surfaces are not held to the same rating as their matt counterparts. All formats in the range are compatible with underfloor heating when installed with a suitable flexible adhesive, but the installation guidance from bodies such as BEAMA’s underfloor heating group is worth following closely on commissioning heating the system gradually before grouting, rather than switching it on at full temperature immediately after installation, is what prevents grout cracking in the following months.
Grout Joint Width and Layout
All formats in the range have rectified edges, meaning the tile is precision-cut after firing so it can be laid with a narrower joint than a standard pressed-edge tile. A 2-3mm grout joint is typical, though this should be adjusted slightly for larger formats or a less-than-perfectly-flat subfloor a slightly wider joint gives more room to correct minor inconsistencies without visible lippage between tiles. Because the veining is a natural-stone-inspired pattern rather than a repeating print, mixing tiles from several boxes and dry-laying a section before fixing is worth the extra hour it takes it avoids an obvious repeat of the same vein pattern appearing twice in the same sightline.
Quick decision rules
- Wet floor (bathroom, wet room, kitchen) → choose matt, not polished
- Dark or low-light room needing more reflected brightness → polished, on a wall or dry floor only
- Small or obstructed room → 30x60cm for easier cutting around fittings
- Open-plan floor wanting the fewest visible joints → 60x120cm, on a well-prepared subfloor
- Uncertain which to pick → 60x60cm sits safely in the middle of both size and practicality
- Always dry-lay a sample area first to check vein distribution before committing
A Note on the Light Grey Sister Colourway
The same Elegant Onyx design also comes in a 60x120cm Light Grey Matt option, which follows identical sizing and performance logic to the beige range above the only difference is the base tone of the veining. It’s worth viewing a sample of both side by side before deciding, since grey and beige onyx effects sit at genuinely different ends of the warm-to-cool spectrum despite sharing the same pattern.

Onyx Beige: Making the Right Tile Choice
Choosing the right Onyx Beige tile comes down to two practical decisions: how much light you want the surface to reflect and which format works best for your space. Compare the matt and polished finishes, consider the room’s size and layout, and choose the format that suits your installation. With those factors in mind, selecting the right Onyx Beige tile becomes a confident decision rather than a guess.
FAQs
Can I mix matt and polished finishes in the same room?
Yes, a common approach is a matt floor with a polished feature wall, using the shared pattern to tie the two together while keeping the practical slip-resistance benefit underfoot.
Is 60x120cm too large for a small bathroom?
It can be, mainly because of cutting waste around fittings a 30x60cm or 60x60cm format is usually more economical and easier to plan in a compact room.
Does the polished finish need sealing?
No, porcelain is non-porous regardless of finish, so it doesn’t require sealing the way natural stone does; routine cleaning with a pH-neutral product is sufficient.
How much extra tile should I order to allow for vein matching?
Beyond the standard 10% cutting allowance, ordering from a spread of box numbers and dry-laying a section first is more effective than simply over-ordering.
Will the beige tone clash with warmer or cooler existing fittings?
It sits close to a true warm neutral, so it generally works with both brass and chrome fittings — the light grey sister colourway is the better choice if your existing fittings lean distinctly cool.
