To lay a tile floor, start by preparing the subfloor and applying a suitable underlayment. Measure and mark the layout to ensure tiles are evenly spaced. Apply thin-set mortar and place the tiles, leaving grout lines between them. Allow the mortar to set, then apply grout and clean excess. Seal the grout if necessary and let the floor cure before use.

Laying a tile floor involves preparing the subfloor, applying mortar, and placing tiles. Benefits include a durable and attractive surface. Challenges include precise layout, curing time, and grout application. Proper installation ensures a long-lasting and professional result.
