A closer look at Onyx
Onyx. Brick in natural stone.
Varied natural stone tones gives this brushed brick mosaic its palette. Rectangular stone pieces form a small-scale brick repeat across the mesh sheets. Brushing gives the stone a gently textured face with a softer response to light.
Natural marble, onyx varies across pieces, sheets and batches.

Brick detail
Rectangular stone pieces form a small-scale brick repeat across the mesh sheets. Listed piece size: 23 x 75 mm. A close grout colour softens the joints; contrast makes the repeat more defined.

Use Onyx as a kitchen splashback or bathroom feature. The brick repeat works alongside quieter cabinetry and fittings; centre complete motifs in the main sight line.

Your Onyx mosaic project
Why choose this brick mosaic?
Brushed brick: Varied natural stone tones. Rectangular stone pieces form a small-scale brick repeat across the mesh sheets.
Where to use this mosaic
Bathroom walls: use the brick as a basin backdrop, niche or feature wall. Wet walls need appropriate waterproofing.
Kitchen splashbacks: relate the varied natural stone tones to the worktop and cabinets. Agree socket cuts and exposed edges before fixing.
Interior floors: listed for walls and floors. Confirm substrate, loading and slip requirements for the actual location. Brushed texture and mosaic joints do not establish a verified wet-slip rating.
Outdoor and frost suitability have not been verified in this guide.
Sheets, boxes and project quantities
Sheet options from the sale variants: 305 × 305mm. Thickness: 10 mm. Sold by the box; listed box quantity: 5 pcs.
The selected variant’s checkout coverage is 0.47m² per box. Price and coverage update when the option changes. Divide the required area by that coverage and round up to a complete purchase unit.
Allow for the brick repeat, perimeter cuts and spares. Add the calculator’s wastage allowance once.
Alignment, grout and sealing
Keep the brick courses level and maintain the offset through the joints between sheets. Dry-lay sheets from several boxes and keep sheet joints consistent.
Use marble, onyx-compatible adhesive, grout and sealer on a suitable substrate. Test grout and sealer first; follow application and curing instructions. Sealing does not prevent acid etching or replace waterproofing.
Care, samples and natural variation
Use a pH-neutral stone cleaner and a soft cloth or mop. Wipe spills promptly; avoid vinegar, acidic descalers and abrasives.
A cut sample shows the brushed texture; a full sheet shows the brick repeat. Natural markings vary across an order.
