Pure uniform bright white quartz with a flawlessly smooth finish — the cleanest, most pristine white available.
Unistone Bianco Extreme represents white quartz at its most absolute. Its uniform, consistent bright white base shows no veining, patterns, movement, speckling, flecking, or granular texture of any kind. The smooth finish is completely clean — a perfect white surface without a single visible imperfection or texture. Bianco Extreme is the purest white in the Unistone range and among the cleanest whites available from any quartz manufacturer. It's designed for spaces that demand pristine, clinical uniformity — high-end contemporary kitchens, gallery-like interiors, and commercial environments where absolute whiteness matters. Manufactured by Brachot with Through Tone Technology. Over 90% natural quartz, NSF certified and antibacterial. 15-year warranty. Available in standard and jumbo slab formats with 20mm or 30mm thicknesses. Supplied and installed by In2Stone across Hampshire.

"Excellent Service and Beautiful Results - Highly Recommended! I recently had In2stone install new quartz worktops in my kitchen, and I couldn't be happier with the results. From start to finish, the experience was completely stress-free. The team was not only competitively priced but also incredibly friendly and professional throughout the entire process. They handled everything seamlessly - removing the existing sink, hob, and old laminate worktops before fitting the new quartz surfaces. The finished worktops are absolutely beautiful and have transformed my kitchen into a modern, minimalist space that I love spending time in. The quality of workmanship is outstanding, and the attention to detail really shows. I'm a very satisfied customer and would highly recommend In2stone to anyone considering new worktops. Well done to the entire team - you've exceeded my expectations!"— Ashley ChapmanGoogle Review
