You may think that installing bathroom vanity units is hard work, something to be left to a professional, but if you have a little DIY knowledge, this job is actually a lot easier than you think.


All you need is time and if you have a DIY knowledgeable friend to come and give you a hand, even better.


Remove Existing Vanity

The first step will be to remove the existing vanity, this is quite a quick process once you understand what you need to do, which of course will start by switching off your water supply.


You can turn the water off at the mains or using the shut off valve inside the existing vanity unit.  Remove the water supply pipes and remove the basin trap. You may want to keep a container close at hand to catch any excess water left over in the pipes to avoid spills.


The next step to removing existing bathroom vanity units is to unscrew the existing vanity unit from the wall, the brackets or screws are often located in the back corners of the unit.


Carefully remove the top or basin, depending what you have on top of your unit. Bear in mind this is often attached with caulk, so be extra careful if you intend re-using the top with the new unit.


Removing drawers and doors can make the unit much lighter to move and once moved you can check the area for any leaks and water damage.


Installing the New Vanity

Installing new bathroom vanity units is as easy as removing them. You will start with your spirit level to ensure your floor is even before you begin. If uneven fix the flooring before adding the new unit.


Mark the area your new vanity is going on the wall, identifying the studs with pencil marks and finding the pipe centres and marking them as well.  Use a drill to make the pilot holes in the back of the new bathroom vanity units and use a hole saw where the water and drainage is to go.


Align your pilot holes with the studs and screw your new vanity into place. You are almost done and ready to switch on the water.


If you have a sink, install that and re-connect your water supply. Go around any connectors with silicone to avoid future leaking. Add some caulk around the edges of the bathroom vanity units before you turn on your water supply.


Once the water supply is turned on, ensure taps are working properly and there are no leaks.
