A bathroom vanity cabinet is a useful space in your bathroom just under the sink where you can store all of your cosmetics and various other products. A vanity can be purchased from local home improvement stores or they made specifically to your requirements. These handy bathroom cabinets make good use of the otherwise wasted space underneath your sink.

Installing and mounting a vanity to your bathroom wall is actually quite easy. With the right tools and accessories, you should be able to complete this project in just a few short hours.

Position the Vanity Unit

Decide where the vanity will go in your bathroom. This will normally be restricted to the location of the sink. Remove your existing sink so it can be replaced with a vanity unit.

Decide where the unit will be located and make marks on the bathroom wall using chalk. Make sure that when the sink is fitted, it will be the right height and will line up with the pipes.

Putting the Vanity Unit in Place

Check that your wall is perfectly level. Among the best ways of doing this is to either use a level or a block of straight wood. Now you need to put the vanity unit in place. A prefabricated vanity unit will not have a back and so will fit right over the pipes for the sink. Check that you are completely happy with the location of the vanity unit, then mark the position of the screw holes onto the wall.

If the wall isn't level then you should scribe the wall levels onto the side of the cabinet or sand the wall down so that it is level.

Mounting the Vanity Unit

Remove the vanity cabinet and set it aside. Using the electric drill, drill the holes into the wall where you have previously marked it. Tap the wall plugs into the wall if required so that they are flush with the surface of the wall. Place the vanity against the wall and use screws to secure the unit in place. Check to make sure that the unit is security fitted so that it doesn't rock or move.

Fixing the Sink

Now you can place the sink into the cabinet. Start by cutting out the shape so that the sink fits inside the countertop snugly. You will then need to physically put the sink in the hole and then connect up the water and drain pipes. Make sure that all of the pipes are tightly sealed so as to avoid any future leaks.

Step 5 - Finishing Touches

Use caulking to seal the gaps between the sink and the vanity unit. Also, run a bead of caulk right down the gap between the wall and the vanity unit. This will prevent water from getting in between the vanity and the bathroom wall.
