While it’s near impossible to answer this question, on average, 150 12 x 12 floor tiles can be laid in a day. However, this number can vary wildly on either side as there are various factors that influence how long it takes to tile a floor. The size of the tiles plays a huge part in how many floor tiles can be laid daily as it will take much longer to tile a floor using small tiles compared to how quickly a large tile installation will go. Other factors that come into play include the size of the floor as well as its shape. You also need to account for any prep work that needs doing, as well as any grouting and cleaning that is required after. Finally, the expertise and experience of the tiler also impacts how many floor tiles can be laid in a day - a novice will work at a much slower pace than a seasoned professional.
