Cabinets and countertops can be the pivotal, "make or break" features of a bathroom. They accent fixtures, flooring and help set the tone and style of the room.
Moreover, they provide needed storage and surface space in one of the house's busiest rooms.
Visitors might not notice a shortage of cabinets or countertop space, but those who use the bathroom daily will definitely see the inconvenience.
Medicine cabinets often go in the back or side walls that frame the vanity and it's easier to put them in before the vanity.
Also, take the doors off all the cabinets to avoid damaging them during installation.
Fit the cabinet snugly between the 2x4's in the stud wall. At the proper height, box in an opening in the drywall between the studs and slide the cabinet in. Level the top of the frame and secure it.
Many vanity cabinets go together with the drawers in or between two cabinets. Most don't have the top fastened because it's easier to handle and fit that later.
Using a level, find the floor's high point to determine the cabinets' high point. Mark a level line through that point across the wall.
That reference line guides all the cabinet tops. Intersect that line with a plumb line down the middle.
Any middle cabinet goes in first. Draw a line down the center of its back and line it up with the guide line.
Transpose pipe locations to the cabinet back and drill pipe holes with a spade bit. Slide the cabinet into place, level the top and secure it to the wall studs with drywall screws.
Flush and plumb the other cabinets. Use a wood clamp to tie the front frames together and screw them together.
NOTE: A gap is often left where a cabinet meets the wall. Fill it in with a trim piece cut to fit snugly in the gap. Screw through the cabinet 's side frame into the trim's side to fasten them.
