Businesses in the ceramic tiles and flags category supply materials for covering and finishing floors, walls and outdoor surfaces. Ceramic tiles are commonly used in kitchens, bathrooms, hallways and commercial interiors, and are available in different sizes, colours, patterns and finishes. Products may include glazed wall tiles, hard-wearing floor tiles, porcelain tiles, mosaics, trims, edging pieces, grout and tile adhesives. Some suppliers also stock natural stone or other tile materials. Flags are flat paving units used to form patios, paths, courtyards and other external surfaces. They may be made from concrete, natural stone or manufactured materials, with choices of thickness, shape, colour and surface texture. Businesses may provide advice on selecting suitable tiles or paving for the intended location, along with samples, measuring guidance and delivery.
