Indoor decorative tiles include wall tiles and floor tiles. Wall tiles are usually ceramic, and the standard for water absorption is 6-10%. Although in the past two years, medium-sized plate porcelain wall tiles have emerged. But we have examined many cases after construction. Medium-slab tiles are not mature enough to be used in walls. Therefore, our company recommends impervious ceramic wall tiles. Its common specifications are 300X600, 400X800MM; in addition to these two specifications, our company also contains 300X900, 750X250MM.
