The Stone
See the natural beauty of Concrete Graphite up close — the surface texture, colour depth, and veining that make this porcelain unique.
Colour:
Grey Mid-grey porcelain with soft, mottled concrete-effect movement — an industrial surface with quiet urban character.
Optimum Concrete Graphite faithfully recreates the patinated, trowelled aesthetic of raw concrete. Its mid-grey base carries a subtle warm undertone and is covered by diffuse, random patches of slightly lighter and darker grey that create a gentle, mottled movement across the surface. There are no veins, no speckling, no granular detail — just the soft, cloudy tonal shifts of poured and cured concrete. The matte, honed finish is essential to the design — it gives the surface a raw, tactile quality that a polished finish would undermine. Concrete Graphite is a dedicated choice for industrial, minimalist, and urban-contemporary kitchens where natural stone and marble aesthetics would feel out of place. As porcelain stoneware, it adds complete heat resistance and UV stability to the concrete look — advantages real concrete cannot match. Manufactured in extra-large 1840 × 3300mm slabs from 100% natural raw materials. 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
