Concrete-effect porcelain stoneware slabs like Boost Smoke can be an excellent choice for interior design. Their warm gray tone offers a softened, sophisticated look that makes spaces inviting yet maintains an edgy, modern vibe. The subtle contrast and textures found in these slabs mimic authentic concrete while providing the durability and maintenance ease of stoneware. This combination creates an evocative and practical flooring solution that harmonizes well with a variety of decor styles, making it suitable for both residential and commercial applications.
