This elegant rigid core design captures the refined beauty of natural honed slate with its versatile grey-pebble colour palette and authentic stone texture, offering the perfect foundation for contemporary, transitional, and modern interiors seeking natural sophistication with neutral versatility. As part of Karndean's innovative Knight Tile Rigid Core collection, Honed Pebble Slate combines the timeless appearance of natural slate with revolutionary click-lock installation technology – no adhesive required, no professional installer needed, and no messy cleanup. The pre-attached acoustic foam backing reduces noise transfer to rooms below by an impressive 19dB, making it the ideal choice for upstairs bathrooms, multi-level homes, and apartment installations where acoustic comfort is essential. Also available in gluedown format as ST20 for downstairs installations where gluedown is preferred, and in coordinating shades including Honed Oyster Slate (ST17) for lighter spaces and Honed Charcoal Slate (ST19) for darker drama, this versatile design brings entry-range pricing with premium rigid core convenience and the reassurance of Karndean's trusted quality. With its neutral grey-pebble tones and authentic honed finish, this design delivers the sophisticated elegance of natural slate without the maintenance demands, cold surface, or installation complexity.

The 19dB noise reduction makes it significantly quieter than laminate or engineered alternatives, perfect for upstairs bathrooms where the elegant slate aesthetic combines with practical noise reduction to rooms below. The neutral grey-pebble colour palette is wonderfully versatile, working beautifully with any décor style from traditional to contemporary, and coordinating effortlessly with any colour scheme. The 100% waterproof K-Core® technology makes it ideal for family bathrooms, en-suites, wet rooms, and utility rooms where natural slate would require professional sealing and constant maintenance. The DIY-friendly click-lock system empowers homeowners to achieve professional natural slate installations over a weekend without the mess, expense, and complexity of adhesive application or the cold, hard surface of real slate. Beyond bathrooms, this sophisticated grey pebble slate design brings timeless elegance to kitchens (where the neutral tones work with any cabinetry colour), creates understated sophistication in living rooms and dining spaces, and adds refined style to hallways and entrances. The ability to install over most existing hard floors makes it perfect for renovation projects, while the K-Core® technology's tolerance for minor subfloor imperfections means less preparation work and faster installation. Whether you're creating a contemporary urban home, a transitional family space, a modern bathroom sanctuary, or updating any room with neutral natural texture, Honed Pebble Slate delivers authentic slate beauty with modern convenience and entry-range affordability. Commercial Applications: Knight Tile Rigid Core's combination of affordability, durability, and quick installation makes Honed Pebble Slate an excellent choice for commercial projects where neutral sophistication, budget, and timeline are all critical. The click-lock floating floor system significantly reduces installation time compared to gluedown alternatives, minimising business disruption and reducing labour costs. The
