When considering the installation sequence of ceramic tiles and doors, it is generally recommended to install the ceramic tiles first. This approach ensures that the door is not damaged during the tile installation process and allows for a more precise fit. According to the National Association of Home Builders (NAHB), ceramic tile installation is typically more delicate and requires a clean, flat surface. Installing the tiles before the door ensures that the door can be properly hung without the risk of damaging the tiles.

The reason for this sequence is rooted in the practicality and ease of the installation process. Ceramic tiles are heavy and can be easily chipped or cracked if they are moved frequently or if heavy objects are placed on them. By installing the tiles first, you create a stable, flat surface that is less likely to be disturbed. This also allows for any necessary adjustments to the door frame to accommodate the tiles, ensuring a seamless fit.

Moreover, the NAHB reports that installing ceramic tiles before the door can save time and money in the long run. If the door is installed first and the tiles are not laid perfectly, it may require additional work to trim or replace the tiles to fit around the door. This can be both time-consuming and costly. By installing the tiles first, you minimize the risk of such issues and ensure a more efficient installation process.

In conclusion, installing ceramic tiles before the door is the preferred method due to practicality, ease of installation, and cost-effectiveness. This sequence minimizes the risk of damage to the tiles and ensures a precise fit for the door.
