The number of boxes of tile you need depends entirely on the amount of tile in each box or case. Different manufacturers package their tiles differently, and boxes contain different amounts of tile depending on the size, shape, and material. Often, the amount of area that a case will cover is listed in the product description. To calculate the number of boxes you need, take the total square feet of the space and divide it by the number of square feet the box will cover.

Porcelain tiles can last 60 years or longer. With high-quality tiles and proper installation, your porcelain tiles may even outlive you, making them well worth the initial investment.

To help your porcelain tiles last longer, you should clean and maintain them regularly. You don’t need any harsh chemicals to get the job done. Rather, use a cloth, hot water, and mild detergent. And don’t forget to learn how to clean floor tile grout, as that’s just as important as tile maintenance.

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.

Yes, you can tile over existing tiles in a bathroom, but it is not always recommended. For this method to be successful, the original tile surface must be clean, flat, and free of damage such as cracks, unevenness, mold, or mildew. While tiling over existing tiles can save time and money, there are potential drawbacks. The new adhesive may not bond properly, and the process adds extra weight to the wall or floor. Additionally, the increased height of the surface could interfere with door clearances. For the best and most durable results, removing the old tiles before installing new ones is generally the better option.
