Yes, but you should only put tile directly on drywall in smaller areas that don’t experience excess moisture. For example, a small kitchen tile backsplash could work, but installing tile directly on the drywall in a bathroom or other chronically damp area is not a good idea. Either way, a cement backer board is a far more reliable solution, as drywall is susceptible to moisture and can warp or cause your tiles to crack.

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.

The best bathroom floor tiles are strong enough to withstand the weight of a clawfoot tub. However, professional tile installation is essential. If the tiles are uneven or improperly fixed, they may crack under the pressure. Be careful when installing the tub—if it drops or drags on the tiles, it could easily cause scratches or cracks.

The average cost for tile installation is about $2,000, with a typical price range between $500 and $6,500. On a per-square-foot basis, you can expect to pay between $5 and $45 for installation.

Several factors influence the total cost, including:

• Installation Site: Costs vary for different areas. Common project costs are: kitchen floor ($870–$6,100), countertop or backsplash ($500–$3,000), bathroom floor ($300–$2,400), or shower wall ($225–$2,000).

• Tile Type and Quality: The material significantly impacts price. For example, standard ceramic or travertine tile can cost about $1 per square foot, while luxury options like marble can be as much as $350 per square foot for the material alone.

• Project Size and Complexity: The total square footage, the complexity of the pattern, and the shape of the tile (e.g., square, rectangle, hexagon, mosaic) will affect labor and material costs.

• Site Preparation: The amount of prep work needed, such as removing old tile or installing a new subfloor or backer board, can add to the final price.

• Tile Characteristics: The tile's durability rating and porosity can also influence the price.

• Location: Labor rates vary by geographic location.
