Flooring materials are selected based on factors like cost, appearance, durability, etc. Tile is a common flooring material made from stone or other hard materials. For tile flooring, a subfloor provides support, tiles are set in mortar and grout is applied between tiles. Vitrified tiles are durable and easy to maintain, with properties making them resistant to chemicals and requiring no polishing. Proper slope, soaking, cleaning, spacing and testing are important for quality tile installation. Skirting provides a finished edge and is made of the same tiles.
