Galaxy Sky Blue Onyx Marble Effect Polished Porcelain Tile 60x120cm

Galaxy Sky Blue Onyx Marble Effect Polished Porcelain Tile 60x120cm

Also known as Sky Blue marble effect, the large-format Galaxy Sky Blue Onyx tile brings deep, dramatic blue marble to walls and floors on a grand scale. Rich ink-blue tones are shot through with paler onyx veining and multi-tonal movement across multiple faces, so the pattern flows naturally without obvious repeats. At 60x120cm the design has room to breathe, and the polished surface gives the colour real depth and a mirror-like sheen — a genuine statement floor or feature wall that won't look like everyone else's.

The large 60x120cm plank format means fewer grout lines and a more continuous, seamless run of colour than a smaller square tile — ideal for opening up bathrooms, hallways and open-plan spaces. Rectified (laser-cut) edges let it lay with very fine joints, and it's rated for underfloor heating.

Why choose Galaxy Sky Blue Onyx 60x120

• Bold, saturated colour — a deep blue marble/onyx effect that's hard to find and makes an instant statement.
• Fewer grout lines — the large plank format gives a cleaner, more expansive finish than smaller tiles.
• Non-porous & low-maintenance — porcelain won't etch or stain the way natural stone does, and never needs resealing.
• Polished gloss finish — reflects light and intensifies the colour for a luxe, high-end look.

Where it works best

This is a feature tile on a large scale — it shines as a bathroom or hallway floor, a full feature wall behind a bath or vanity, or a bold open-plan kitchen floor. The deep blue pairs beautifully with brushed brass and gold brassware for warmth, or chrome and matt-black for a cooler, contemporary scheme, and sits well against white sanitaryware and pale cabinetry that let the colour take centre stage.

As a polished tile, keep it to interior use and pair it with a matt or textured tile for shower trays and step-in areas that need more grip.

Care & sealing

Porcelain doesn't need sealing the way natural stone does, but on polished tiles a one-off application of a quality impregnating sealer after fitting helps repel grout haze and everyday marks. Clean with warm water and a pH-neutral tile cleaner — avoid acidic or bleach-heavy products that can dull the gloss over time. With a large-format tile, a flat, well-prepared substrate and the right adhesive bed are key to avoiding lippage.

Prefer a smaller format?

The same deep-blue design is also available in a square Galaxy Sky Blue Onyx 60x60cm tile — ideal for smaller rooms, cloakrooms and feature areas.

Frequently asked questions

Is Galaxy Sky Blue Onyx the same as the "Sky Blue" marble effect tile?
Yes — this is the same deep-blue polished porcelain design, sometimes listed as Sky Blue marble effect, here in the large 60x120cm format. The 60x60cm version is the same tile in a square size.

Is a 60x120 tile suitable for walls?
Yes, it's rated for both walls and floors. Large-format tiles are heavier, so on plasterboard or stud walls fit a tile backer board first and use the correct adhesive for large-format porcelain.

What grout colour works best with deep blue tiles?
A grey or anthracite grout keeps the joints discreet and lets the blue dominate, while a white grout creates a crisp, graphic grid if you want the tile shapes to stand out. Both work — it depends whether you want the joints to recede or frame each tile.

Can these go over underfloor heating?
Yes. The tile is suitable for both electric and water-based underfloor heating when laid with a flexible adhesive and grout.

How many tiles do I need?
Each tile covers 0.72m², so you need roughly 1.39 tiles per square metre. Take your area in m², add around 10% for cuts and breakages, then divide by 0.72 — or use the area calculator at the top of this page.
