Slatpanel® Hydro Walnut Waterproof Wall Panels

Say hello to the Slatpanel® Hydro in walnut - our iconic slat wall panel, reimagined for the spaces where style meets steam. Bathrooms, shower enclosures, wet rooms, kitchen backsplashes - these are the rooms that deserve beautiful panelling just as much as any other in your home, but until now, traditional wood slat panels simply weren't up to the job. The Slatpanel® Hydro range changes that. Built around the same slat profile that has made our panels one of the most sought-after wall finishes in interior design, the Hydro takes that formula and makes it water-ready. Each panel features a polystyrene (PS) core wrapped in a clear coat PVC layer, creating a surface that shrugs off splashes, steam, and humidity without breaking a sweat. That PVC coating also makes cleaning genuinely effortless - a quick wipe is all it takes to keep your panels looking as fresh as the day they went up. Despite their robust construction, Hydro panels are remarkably lightweight, making them easy to carry, cut, and position - even when working in the confines of a shower enclosure. Installation is handled via a tongue and groove system - panels click neatly together for a seamless, professional finish. For the cleanest look, panels should be fixed using a grab adhesive only; avoid screws, which would detract from the seamless finish. Sealant should be applied along the tongue and groove edge to close the small gap between panels, preventing water and moisture from getting behind the installation. The walnut color features a printed wood grain effect that delivers real depth and warmth - giving you the authentic look of timber without any of the upkeep. To complete the installation properly, we also offer a dedicated Slatpanel® Hydro Adhesive and Sealant , available in both black and white, designed specifically to work alongside these panels. Rich, deep tones for a bathroom with real drama and depth. The walnut color brings a deeper, moodier warmth to your space — perfect for bathrooms where you want to make a statement. The darker, richer wood grain print adds a layer of luxury that pairs effortlessly with matte black fixtures, dark grout, and statement lighting. Think dark and dramatic ensuites, sophisticated wet rooms, and contemporary bathrooms that lean into contrast and depth. Walnut is the choice for spaces where bold, considered design takes center stage.
