Floating means there are no legs, it is attached to the wall at whatever height you would like. Floating vanities are nice because of what I mentioned, you can hang it whatever height you would like, there is potential storage underneath, and it makes the space feel more spacious.

Hi Mia, thanks for reaching out! A floating vanity is one that is attached to the wall which gives you the freedom to decide how high you want it as opposed to a vanity with legs that has a fixed height. Hope this helps! - Taymour
