Updating your bathroom with a new bathroom vanity can be an efficient way to completely change the look of your bathroom. Even if you're not an expert with tools, replacing an existing bathroom vanity is a fairly straightforward process that is much easier than you might think and can be completed in just a few hours. With unlimited possibilities for designs and finishes from rustic to modern, the most difficult task will be selecting a new vanity that suits your personal style.

Installing Bathroom Vanities:

  1. Remove the old vanity. Shut off the water supply and disconnect the drain lines. You may need to use a crowbar to separate the vanity cabinet from the wall, so be careful not to damage the sheet rock. If you plan to reuse the sink and countertop, remove them from the cabinet and store them safely.

  2. Prepare the area. Use a stud finder to locate the studs in the area behind where the vanity will go. Mark the location of each stud with a pencil.

  3. Set the vanity. Place your new vanity in the space and use the level to determine if the piece is level from front to back and side to side. Use shims to shore up sides that sit lower than others, and trim the shims with a utility knife to be flush with the front of the vanity. You may also want to paint or stain the shims to match the cabinet.

  4. Secure the cabinet. Drill screws through the top rail alongside the back of the cabinet to attach it securely to the wall studs. This will prevent the vanity from rocking or tipping.

  5. Top it off. Place the countertop on the cabinet and screw the countertop to the cabinet on the underside of the counter. Place the sink in the sink hole, and caulk around the edges to hold it in place. The sink may also have sink clamps that need to be attached on the underside.

  6. Hook up the plumbing. Reconnect the water supply and drain lines and turn the water back on. Watch carefully for drips or leaks that may need to be sealed.

Bathroom Vanity Installation Tip:

  1. To make this project even easier, purchase a bathroom vanity that has a sink and countertop already attached. This can prevent a lot of problems than can arise when you have mismatched pieces.
