The bathroom has changed over the years from modest room to a multi-purpose area and installing a bathroom vanity allows more storage in a limited space. There are hundreds of different options of cabinets as well as sinks and hardware that can make this unit a one-of-a-kind show-piece for the bathroom area.

Installing a bathroom cabinet is a relatively easy project that any do-it-yourselfer will be able to accomplish. It can totally change the look of the room with only a few hours of work can be completed with a few simple tools and a spare weekend. Buying a bathroom vanity requires that that unit can fit into the space while making allowances for the other fixtures as well as the door swing. It is also important to check out the plumbing considerations.

Before Assembly


The bathroom cabinets mentioned here are called "face frame" cabinets. This means meaning they have a ¾" thick frame around the front of the cabinet box. (Frameless cabinets sometimes called European cabinets are box construction without the frame.)
Bathroom cabinets should be made from solid woods such as maple, oak and cherry that can handle moisture and humidity or sealed composite products such as melamine.
Make a drawing of bathroom floor plan using graph paper. This will help keep the scale accurate. Mark out the room dimensions, toilet and bath/shower locations and window (if there is one) and door swing.
Make sure the plumbing behind the walls is secure and there are not leaks. If the wall has been water damaged fix with new wall sheathing and paint.


Remove the old cabinet as well as the baseboard along the bottom of the wall. The cabinet is installed directly on the finished floor.
Paint and install flooring beforehand to make installation seamless and to avoid harming the cabinet afterward.
Unlike kitchen cabinets most bathroom cabinets have holes pre-drilled for door hinge and drawers
