Installing a wood door before tile is generally recommended. This sequence ensures that the door is not damaged during the tile installation process. According to the National Association of Home Builders (NAHB), tile installation can be quite messy, with grout and mortar splatters that can potentially damage a newly installed door. By installing the door first, you create a barrier that protects it from these materials. Additionally, the door can serve as a temporary wall to contain dust and debris during the tile work. This approach also allows for easier adjustments and modifications to the door opening if needed, as the tile installation may require slight adjustments to the door frame.
