Pay attention to the age of your home and the remodels done by previous homeowners. Putting new tile over a foundation rife with dry rot or severely outdated or junky plumbing is only delaying a potentially huge problem down the road. You may want to wait until you can do a complete job right.
When choosing the size of your mirror, you should consider not just function, but also proportion. To create a balanced look, think about the size of your mirror relative to that of your vanity. Typically, vanity mirrors are not wider than the vanity itself, with some exceptions we will discuss a little later.
The bathroom shown here, done by Case Remodeling for $30,000 to $35,000, is an example of a midrange bathroom remodel. It features porcelain tile, a his-and-her semicustom vanity, granite countertops and brushed-nickel plumbing fixtures.
Using several tall and skinny mirrors can give a room a more vertical look, emphasizing the height of the space (especially effective when you have high ceilings). Of course, using a single large mirror opens up the room by reflecting more of the opposite walls. Ultimately the choice comes down to personal preference.
