Height suggestions for the vanity top... In general, vanities need to be about 36-37 inches tall to be suitable for most people. If you are using a vessel sink then you need a piece which is about 30 inches tall or table height. Sometimes we can make some height adjustments on the feet, both taller and shorter.
As a set rule, the mirror should measure several inches fewer on each side than the vanity or sink area. For example, if you've found a single sink 48 inch vanity for sale that you intend to use, you will want to select a mirror that's width (frame included) doesn't exceed 42-44 inches total. Some people may choose a mirror that goes to the very edge of the vanity top.
