    What Is an Onyx Green Marble Effect Polished Porcelain Tile?

    An onyx green marble effect polished porcelain tile is a vitrified porcelain tile with a digitally printed green onyx pattern and a polished face. Porcelain is a dense ceramic body with water absorption of 0.5% or less, which places it in Group BIa of the EN 14411 tile standard. That low absorption is why porcelain resists water and stains far better than natural stone.

    The Tiles Paradise Onyx Green tile has a deep green background with dramatic, marble-style veining. The polished finish adds depth, so the pattern looks layered rather than flat.

    What does "onyx marble effect" mean on a tile?

    "Onyx marble effect" means the tile imitates onyx marble, a banded, semi-translucent stone. Onyx shows flowing parallel bands of colour. Classic marble shows cloudier, branching veins. This tile blends both: the base colour and banding come from onyx, and the finer veins come from marble.

    Is Onyx Green real onyx stone?

    Onyx Green is not real onyx stone. It is porcelain that reproduces the look of onyx. Natural onyx is soft, porous and usually needs sealing. Porcelain gives a similar appearance with lower maintenance and a lower price per m².

    What Are the Specifications of the Onyx Green 60x120cm Tile?

    The specifications of the Onyx Green tile are listed below, taken from the Onyx Green Marble Effect Polished Porcelain 60x120cm product page.

    What does rectified mean for this tile?

    Rectified means the tile edges are machine-ground after firing so every tile has straight edges and near-identical dimensions. Rectified tiles can be laid with narrow 2–3mm grout joints. Narrow joints keep the onyx pattern flowing from one tile to the next.

    Why does the 60x120cm size matter?

    The 60x120cm size matters because fewer, larger tiles create fewer grout lines. A 1.44 m² wall needs only two tiles. Fewer joints make a room look larger and make cleaning faster.

    How Much Does Onyx Green Polished Porcelain Tile Cost in the UK?

    Onyx Green polished porcelain costs £25.99 per m² at Tiles Paradise (sale price, 38% off the £41.65 RRP). One box costs about £37.43. A single 0.72 m² tile works out at about £18.71. Comparable polished green onyx-effect 60x120cm porcelain tiles were listed at roughly £35 to £90 per m² across UK retailers in September 2026.

    Buying option Coverage Price Price per m²
    Single box 1.44 m² (2 tiles) £37.43 £25.99
    Pallet deal 46 m² (64 tiles) £899.00 (RRP £1,100) about £19.51

    20x50cm sample 0.10 m² £7.99

    Delivery is free on orders over £499 to UK mainland addresses, usually within 2–4 working days. Orders between £100 and £499 cost £39.99 to deliver. Pallets are delivered kerbside, so plan for help moving the boxes indoors.

    How many boxes of Onyx Green tiles do I need?

    You need your floor or wall area in m², plus 10% for cuts and breakages, divided by 1.44 and rounded up. Add 15% instead of 10% for diagonal layouts or rooms with many corners. The examples below use the 10% allowance and the £25.99 per m² sale price.

    Project Area Area + 10% Boxes Tiles Tile cost
    Shower feature wall (1.2m × 2.4m) 2.88 m² 3.17 m² 3 6 £112.28
    Small bathroom floor (1.8m × 2.2m) 3.96 m² 4.36 m² 4 8 £149.70
    Kitchen floor (4m × 3.5m) 14.00 m² 15.40 m² 11 22 £411.68
    Open-plan floor 40.00 m² 44.00 m² 31 62 £1,160.19

    The open-plan example shows when the pallet makes sense. Buying 31 boxes costs £1,160.19, while the 46 m² Onyx Green pallet deal costs £899 and leaves about 2 m² spare. For any project above roughly 35 m², compare both options. The free Tiles Paradise tile calculator works out box numbers for other room sizes.

    Should I buy all boxes in one order?

    You should buy all boxes in one order. Porcelain is fired in production batches, and shade can vary slightly between batches. One order keeps the green tone consistent and gives you spare tiles from the same batch for future repairs.

    Where Can You Use Onyx Green Polished Porcelain Tiles?

    You can use Onyx Green polished porcelain tiles on indoor walls and indoor floors. The polished face makes it strongest on walls and on floors that stay dry.

    Area Suitability Why
    Bathroom feature wall Excellent Gloss and veining are seen at eye level; no slip concern
    Shower walls and wet room walls Excellent Porcelain resists water; large tiles mean fewer grout lines to clean
    Kitchen splashback Excellent Wipes clean; porcelain tolerates heat behind a hob
    Living room or dining floor Very good Dry area; works with underfloor heating
    Bathroom floor (outside the shower) Good with care Use a bath mat; gloss is slippery when wet
    Kitchen floor Good with care Wipe spills quickly; add mats at sink and hob
    Hallway or entrance floor Use with care Grit from shoes can dull the polish; use entrance matting
    Shower tray or walk-in shower floor Not recommended Polished surfaces become slippery under running water
    Outdoor patio or balcony Not suitable Listed for indoor use only

    Can Onyx Green tiles go on a shower wall?

    Onyx Green tiles can go on a shower wall. Porcelain does not absorb water, and 60x120cm tiles reduce the number of grout joints where mould can start. Waterproof the wall behind the tiles with a tanking system before tiling.

    Can Onyx Green tiles be used on a bathroom floor?

    Onyx Green tiles can be used on a bathroom floor in the dry zone. Place a bath mat where you step out of the bath or shower. For the shower floor itself, choose a matt tile with a higher slip rating and keep Onyx Green on the walls.

    Can Onyx Green tiles be used outside?

    Onyx Green tiles should not be used outside. The tile is listed for indoor use, and a polished surface is unsafe on wet patios. Outdoor areas need 20mm matt porcelain with a high slip rating.

    Is Polished Green Onyx Porcelain Slippery?

    Polished green onyx porcelain is slippery when wet, like all high-gloss tiles. Dry, it is comfortable to walk on. In the UK, floor slip resistance is often shown as an R-rating from the DIN 51130 ramp test, where R9 is the lowest rating and R13 the highest. Polished porcelain generally sits at the low end of that scale, so it suits walls and dry floors better than wet floors.

    Listed below are simple ways to keep a polished floor safe:

    • Use absorbent mats beside baths, showers, sinks and entrance doors.
    • Wipe up water and cooking spills straight away.
    • Clean with pH-neutral cleaner only, because oily or waxy products leave a slippery film.
    • Choose a matt anti-slip tile for shower floors and ramps.
    • Consider a matt floor with Onyx Green walls in homes with elderly relatives or young children.

    Does Onyx Green Porcelain Need Sealing?

    Onyx Green porcelain does not need sealing. Its porcelain body absorbs almost no water, so stains stay on the surface and wipe away. Natural onyx and marble are different: they are porous and need regular sealing.

    One practical tip helps with dark or strongly coloured grout. Polished faces can hold grout pigment in microscopic surface pores. Test your grout on a spare offcut first, and clean grout residue off the face within the time stated on the grout bag.

    What Colour Grout Goes With Onyx Green Tiles?

    The best grout colour for Onyx Green tiles is mid-grey or anthracite, because both blend into the darker veining. The choice depends on whether you want the tiles to read as one surface or as a grid.

    Grout colour Look Best for Example grout
    Medium grey or cement grey Soft, blended joints Most bathrooms and kitchens Mapei Ultracolor Plus 112 Medium Grey or 113 Cement Grey
    Anthracite Near-seamless, slab-like Feature walls and dramatic schemes Mapei Ultracolor Plus 114 Anthracite
    Silver grey Light, clean outline Bright rooms with white sanitaryware Mapei Ultracolor Plus 111 Silver Grey
    White Every tile outlined Graphic, grid-style designs Mapei Ultracolor Plus 100 White
    Black High contrast Black-framed fittings and bold modern rooms Mapei Ultracolor Plus 120 Black

    Light grout shows dirt faster on floors. White grout on a green floor usually needs more cleaning than grey.

    What Goes With Green Onyx Tiles?

    Brushed gold, warm wood, crisp white and matt black go well with green onyx tiles. Deep green is a strong base colour, so the rest of the room should either warm it up or calm it down.

    Listed below are pairings that work with Onyx Green:

    • Brushed gold or brass taps and showers: the warmest, most luxurious match for polished green.
    • White sanitaryware and white walls: keep a small room bright and let the green wall lead.
    • Walnut or oak vanity units: add natural warmth and soften the gloss.
    • Matt black fittings: create a darker, modern contrast.
    • Cream or white onyx tiles on the other walls: Onyx Green shares its 60x120cm format with the Onyx Cream, Onyx White, Onyx Blue, Onyx Pink, Onyx Black, Onyx Light Grey and Onyx Dark Grey tiles, so edges and grout lines align.
    • A matt neutral floor: balances a polished green wall and adds grip underfoot.

    Is Onyx Green a good choice for a small bathroom?

    Onyx Green is a good choice for a small bathroom when you use it on one or two walls instead of every surface. The polished finish reflects light, and 60x120cm tiles reduce visual clutter. Pair it with white sanitaryware, good lighting and a lighter floor so the room does not feel enclosed.

    Will green onyx tiles go out of fashion?

    Green onyx tiles follow a strong current interest in rich, stone-inspired colour, so no one can promise they will never date. Deep green has a long history in British interiors, from Victorian tiling to modern boutique hotels. Using it on a feature wall makes it easy and affordable to update the room later.

    How Do You Install 60x120cm Polished Porcelain Tiles?

    You install 60x120cm polished porcelain tiles on a flat, sound substrate using flexible S1 adhesive with full coverage and a levelling clip system. Large tiles are less forgiving than small tiles, so preparation decides the result. Hiring a tiler experienced with large-format porcelain is the safest option.

    1. Check flatness. Large-format tiles need a very flat base. BS 5385 guidance generally allows no more than about 3mm deviation under a 3m straight edge. Level uneven floors with a flexible levelling compound.
    2. Check the wall can take the weight. Porcelain plus adhesive is heavy. Cement tile backer board is a strong base for full-height walls.
    3. Dry-lay the tiles. Lay out tiles from several boxes first. Shuffle them so the veining flows naturally and similar patterns do not sit side by side.
    4. Use flexible S1 adhesive. A C2 S1 (flexible) cement-based adhesive copes with the slight movement that large tiles and heated floors create.
    5. Get full adhesive coverage. Spread adhesive with a large notched trowel (often 10–12mm) and back-butter each tile. Aim for no hollow spots, especially on floors.
    6. Use levelling clips. Clips and wedges stop lippage, where one tile edge sits higher than the next. Lippage is very visible on gloss tiles because light catches the step.
    7. Keep a 2–3mm joint. Rectified edges allow narrow joints. Do not butt-joint tiles with no gap.
    8. Avoid a half-bond on long tiles. Large rectangular tiles can bow slightly. An offset of no more than one-third of the tile length reduces uneven edges.
    9. Leave movement joints. Add flexible silicone joints at room perimeters, internal corners and changes of material.
    10. Grout after the adhesive cures. Follow the adhesive bag for curing time, then grout and clean the polished face promptly.

    For a deeper walkthrough of joints and edge accuracy, read the guide to rectified porcelain tiles.

    Can plasterboard or a plastered wall hold 60x120cm tiles?

    Plasterboard can hold 60x120cm porcelain tiles in many cases, but plaster skim often cannot. BS 5385-1 commonly cites about 32kg per m² (tiles plus adhesive) for plasterboard and about 20kg per m² for plaster. A 9mm porcelain tile with a solid adhesive bed can approach or exceed the plaster limit. Board the wall with cement backer board if in doubt, and see the guide to marble wall tile weight limits in wet rooms before tiling a shower.

    Can Onyx Green be laid over underfloor heating?

    Onyx Green can be laid over both electric and water-based underfloor heating. Porcelain conducts and holds heat well. Switch the heating off before tiling, use flexible S1 adhesive, and bring the temperature back up slowly after the adhesive and grout have cured. A decoupling membrane helps on new screeds or floors prone to movement. The step-by-step guide to laying porcelain floor tiles on concrete and underfloor heating covers timings in detail.

    How do you cut polished porcelain without chipping it?

    You cut polished porcelain without chipping it by using a wet saw or a rail cutter long enough for 1200mm tiles and a sharp diamond blade made for porcelain. Put masking tape over the cut line to protect the gloss. Cut slowly, support the whole tile, and smooth cut edges with a diamond hand pad.

    How Do You Clean and Maintain Polished Green Porcelain?

    You clean polished green porcelain with warm water, a pH-neutral tile cleaner and a microfibre mop or cloth. Dry the surface with a clean cloth for a streak-free shine.

    Listed below are the maintenance rules for polished porcelain:

    • Do sweep or vacuum floors often, because grit causes fine scratches on gloss.
    • Do squeegee shower walls after use to prevent limescale spots.
    • Do put felt pads under chair and table legs.
    • Do not use abrasive pads, scouring powders or wire wool.
    • Do not use wax, oil soaps or "shine" products, which leave a slippery film.
    • Do not leave acidic descalers on grout for long periods.

    Onyx Green Porcelain vs Natural Green Onyx vs Green Marble: Which Is Better?

    Onyx Green porcelain is better than natural green onyx or green marble for most UK homes because it needs no sealing, resists stains and costs less. Natural stone offers unique slabs and genuine translucency, but it needs more care.

    Attribute Onyx Green porcelain Natural green onyx Natural green marble
    Material Vitrified porcelain Banded calcite stone Metamorphic stone
    Water absorption 0.5% or less Porous Porous
    Sealing Not needed Needed regularly Needed regularly
    Stain resistance High Low (acids etch) Low to medium
    Scratch resistance Good Soft, scratches easily Moderate
    Pattern Printed, repeats across faces Every slab unique Every slab unique
    Underfloor heating Yes Case by case Yes, with care
    Price at Tiles Paradise £25.99 per m² (sale) Typically much higher Typically higher
    Best use Walls, showers, dry floors Feature panels, backlit walls Floors, vanity tops
