How to Raise a Bathroom Vanity. Bathroom vanities all come in a standard height that is a little shorter than that of kitchen cabinets. For some, this height is too short and can actually cause discomfort from bending over to access it. Do you wish your vanity was taller? Read this eHow. Help is on the way.
Pry the vanity up from the floor with a pry bar. Be careful not to mar the bathroom floor. Put a piece of wood or thick towel down to set the bar on. Set the vanity aside on a surface that will not be scratched or otherwise damaged.
Secure 2 inch by 4 inch or 2 inch by 6 inch blocking to the floor with screws in the footprint of the vanity. Be sure to recess the blocking just a little so it won't stick out from beneath the vanity when you replace it.
Replace the vanity and secure it to the blocking with screws.
Hide the blocking by either installing ceramic tile to the front of the blocking that matches that of the floor or whatever is in your shower. You can also mask the blocking by putting hardwood flooring over it as well. An alternative solution is to use glass block. For added interest, you can install a fluorescent light behind the glass block.
Consider replacing your bathroom vanity altogether and use a kitchen cabinet instead. Kitchen cabinets are generally taller, and come in a variety of styles. You would have to add a larger counter top, as bathroom vanity counters usually extend further than that of kitchen ones. You would also have to add door fronts as well as doors.
Call your electrician if anything is affected by raising your vanity. An electrician should move any switches or plugs so they can still be easily accessed.
