Tile installation can be expensive because it requires more time and labor to install than many other materials. For example, laminate flooring can click and lock into place, and carpet comes in large rolls that you can secure to the floor. On the other hand, tiles need to be cut, laid individually, grouted, and left to cure.

Silicone caulk shouldn’t be used in place of grout because each material serves its own purpose. Thanks to its flexibility, silicone caulk is good for sealing around the perimeter of tiled floors, where movement and expansion might occur. However, grout is more durable, making it a better option for the joints in between tiles, which need to withstand constant weight and foot traffic.

Figure out how much tile you need by measuring the backsplash area. Measure the height and length in feet and multiply to get the square footage. Don’t make adjustments for outlets or small cutouts but subtract the square footage for windows or other large obstructions from the total. To account for waste, get 10% more than your calculation.

The difference between floor and wall tiles is that floor tiles generally have higher strength and porosity ratings than wall tiles. Wall tiles are typically weaker and more likely to crack or become damaged under sustained pressure like high foot traffic. 

For this reason, avoid using wall tiles on floors and vice versa.
