2.1 The contractor you are hiring
Local contractors are usually cheaper to be hired in comparison with international or renowned contractors. Certainly, it will also affect the quality of work.
Local contractors may not provide you with good quality of service as compared to the international one, but this is not always true.
2.2 Floor sizes
The size of the tile floor to be finished also affect the costs.
The more area you need to finish, the lesser is per square ft cost of finishing. This is mainly the distribution of various associated costs due to larger areas. Overhead costs in small floor areas are higher per square than large floor areas.
2.3 Type of tile
The ceramic wood tile installation cost will be much lower compared to granite and marble.
Natural stones are very expensive and can cost as much as 50% more than ceramic or porcelain. Also, natural stones will require sealing after the installation process. Again, this will cost more money. However, natural stones are stronger and have good resistance against wear and tear.
2.4 Requests for custom work
Patterns, mosaics, prints, and borders are the custom works apart from simple tiles fixing. Such floors may take more time and resources to finish, which is why you must pay more.
2.5 Preparation of surface
Usually, If your concrete floor needs leveling and extra prep work, the installation cost will be much higher. In this case, the installer would need more time to spend more time to prepare the floor for the tiles.
2.6 Accessibility of installation area
Apply tile floors on the areas that do not have better accessibility would result in more labor costs. For example, applying tiling to the floor of complex building apartments would cost you more than the single-family houses with simpler plans.
2.7 Cutting needs for the floors
If your floor design has lots of corners, the contractor would have to cut the tiles many times to fit in the corners. Again, more work means more expenses. Aside from the fixed rate per square foot, the contractor may add an overhead fee for the extra effort.
For tiled floors, it may cost you around 20 USD to 60 USD per square foot. Certainly, it all depends on the type of tiles you are buying and other factors listed above.
