Multipanel Linda Barker Onyx Marble Shower Panels - T&G

Yes – Multipanel panels provide a 100% waterproof surface for your bathroom. They’re specifically designed for wet areas like showers, and unlike tiles they require no grout (so you won’t have any porous grout lines that can leak or get moldy). When properly installed, the tongue-and-groove panel joints are sealed, creating a watertight finish that keeps moisture out. In short, you can confidently use these panels in place of tiles and have a fully waterproof, leak-proof bathroom wall.

Yes. One big convenience of wall panels is that they can be fitted directly over old tiles as long as the tiled wall is sound and level. There’s no need to chisel off your current tiles – you can simply glue the panels on top, instantly covering dated or tired tilework. Multipanel’s system is made to adhere to almost any stable surface (tiles, plasterboard, timber framing, etc.), so you can renovate a bathroom without the mess of rip-out. Just ensure the existing tiles are securely fixed and clean before panel installation. This ability to overlay panels on old tiles saves a huge amount of time and hassle during a remodel.

Cleaning Multipanel wall panels is quick and easy; much easier than cleaning tiled grout lines. The panels have a smooth, non-porous laminate surface, so dirt and soap residue don’t cling on. In most cases a simple wipe-down with a microfibre cloth and mild detergent is all you need to keep them looking like new. Because there’s no grout, you won’t get the typical mould or mildew buildup at the joints. In fact, the panels are formulated to resist staining and have excellent mould and bacterial resistance, so your bathroom stays hygienic with minimal effort. There’s basically no maintenance required beyond regular wiping – no re-sealing, no re-grouting, and no scrubbing with harsh chemicals.

These wall panels are extremely durable and built to last for decades. Multipanel backs this with a 30-year warranty on its bathroom wall panel ranges, which covers issues like cracking or de-lamination as long as the panels are installed and cared for correctly. The construction of the panel is high-quality: a tough decorative laminate bonded to a waterproof exterior-grade MDF core (engineered wood made to withstand prolonged moisture). This means the panels won’t warp, swell, or peel due to bathroom humidity, and they won’t easily crack or chip from everyday impacts the way some tiles might. With normal use, you can expect the panels to stay waterproof and look great for many years – their long warranty reflects the confidence in their longevity.

Yes, these bathroom panels can be applied directly or to timber sub-frames, using the Multipanel wall panel adhesive.
