Tradeline Royal Grey Marble Matte MDF Wet Wall Panel – Square Edge, 2420 x 1200 x 11mm

Bring soft grey marble elegance with fine natural veining to your bathroom with the Tradeline Royal Grey Marble wet wall panel. Behind the high-pressure laminate face sits a moisture-resistant MDF core with a laminate compensator backing, which is what keeps the board flat and stable in a humid room rather than bowing over time. The result is a completely grout-free, waterproof wall that goes up in an afternoon instead of the days tiling would take.

Why panels instead of tiles

• No grout. Nothing to discolour, crack or scrub — the single biggest maintenance complaint in a tiled bathroom simply doesn't exist
• Far quicker to fit. A shower enclosure is typically a single day rather than several
• Goes over existing tiles. No hacking off, no skip, no re-plastering, provided the existing tiles are sound and firmly bonded
• Hygienic. The non-porous laminate surface gives mould and bacteria nothing to hold on to
• Wipes clean with a damp cloth and mild detergent

Product Details

Square edge – what that means for fitting

Square edge panels butt up against a trim rather than slotting into each other. Where two panels meet on the same wall you will need an H-section trim between them. This gives you a visible trim line at each joint — some people prefer that defined look, and it also makes the panels more forgiving on walls that are not perfectly plumb.

How many do I need?

Each panel covers approximately 2.9m². As a rough guide, a standard shower enclosure of three walls takes three to four panels, and a full bath surround typically takes two to three. Measure each wall, divide by the panel width, and round up — offcuts are useful for reveals and it is far better than being one panel short mid-fit.

Fitting notes

• The wall must be sound, dry, flat and free of dust, grease and loose material
• Panels can be fitted directly over existing tiles provided the tiles are firmly bonded and degreased
• Apply panel adhesive in vertical beads, so any moisture behind the panel can drain rather than pool
• Seal every cut edge. The MDF core is exposed wherever you cut, and that is where water gets in. This is the single most common cause of panel failure
• Cut with a fine-tooth blade, face up, to avoid chipping the laminate surface
• Allow the panel to acclimatise in the room for 24 hours before fitting
• Finish visible junctions with Topseal colour-match sealant rather than a standard white silicone
