Re-doing a bathroom floor can be a fun and exciting project. Although oftentimes daunting, it is a fairly simple process which many people can complete on their own.
Begin by removing the toilet and existing vanity from the space. The next step is to demolish the existing tile floor and look for loose boards or rot from a previous floor. Once those issues have been fixed, put down a new backer board, install the tile, and insert the new or existing toilet and vanity.
