Ceramic tiles can be used on top of existing coverings and flooring (ceramic, stone, painted plaster) provided that these are not damaged in such a way as to compromise the stability of the new material (tiles coming loose, cracking). Some materials may require additional treatment before going ahead with the new application.
How to make a floor plan:
With the help of a tape measure, measure the long side and the short side of your bathroom.
Create a simple drawing and write down the measures.
Also add structures: doors, windows and sanitary items.
If you want you can also add measures for doors and windows and their distance from the wall.
If you want to remove any sanitary ware please mark with an X.
The more information you add, more accurate your bathroom will be.
