These Matt Carrara Marble wall panels are Guardian Neptune 250 PVC boards in a matt white marble décor with soft grey veining. Carrara is the classic pale marble look — bright field, light vein — without the shine of a gloss marble sheet.
Size: 250mm wide × 2.6m long × 7.5mm thick
Pack: 4 pattern-matched panels
Pack coverage: 2.6m²
SKU: MATT_CAR_MARBLE_GUARD
Use Matt Carrara Marble wall panels on bathroom walls, shower enclosures (with the right trims and seals), wet rooms, cloakrooms and kitchen splash areas away from intense hob heat. The 250mm plank breaks the wall into slim marble “slabs”. Matt keeps the vein visible without turning every downlighter into a hotspot.
This is printed PVC, not quarried stone. You get the Carrara look, a wipe-clean face and no grout grid. You do not get the cold mass or the unique slab of real marble — and you do not get the sealing and staining jobs either.
Also known as: matt Carrara panels, Carrara marble PVC, Neptune Carrara, matt marble wet-wall panels.

Dry-lay the vein before you glue. Carrara only looks expensive if the grey lines do not jump at every joint.

The marble look without the stone jobs
Real Carrara stains, needs sealing and costs in slabs. These Matt Carrara Marble wall panels print the vein on waterproof PVC.
Matt, not a glossy showroom
Vein stays readable. Spots do not flare off the wall.
Waterproof face
Steam sits on plastic. Seal trays, taps and corners.
No grout to go black
T&G replaces the tile grid — the usual place mould shows on cheap marble-effect tiles.
250mm × 2.6m is a bathroom module
One length for most wall heights. Four boards = 2.6m².
7.5mm Neptune 250
Light to handle, stiff enough on a decent wall.
Faster than tiling marble
No adhesive bed over every tile, no grout haze, no sealing day.
Can go over old tiles
If they are flat and well stuck.
Pattern-matched pack of 4
Blend boards so the vein runs as one design.
5-year range warranty
Keep the pack notes.
Fix mixers and glass channels through to the substrate.
