Finally, before you make your final decision to fix the new tiles over the existing ones
, it is important to consider all the pros and cons. For instance in-case there are some loose tiles among the existing ones, you might be forced to remove the whole cover for best results. Another consideration is the aesthetic you intend to achieve. If the existing tiles are not completely flat, laying new tiles over them will only amplify the imperfection. It is therefore important to consider all these options before embarking on your DIY project.
