Step 1. Remove the old sink
Prior to fitting your new bathroom vanity, you’ll have to turn off the water supply and disconnect the water supplies for the hot and cold valves, as well as the sink waste. After this has been done, you can remove the old sink.
A bathroom sink is typically fitted to the wall using screws or sealant, both of which are easily removable. If the sink is screwed to the wall, remove the screws and ease it away from the wall. If sealant has been used to fit the sink to the wall, there are a couple of ways you can remove it. Using sealant remover is an obvious option, or alternatively, you can apply heat to the area using a heat gun, and slice the sealant away with a blade. Slowly and carefully detach the sink from the wall.
Step 2. Positioning the bathroom vanity
Measure the bathroom vanity and decide on the best position, helping to prevent you from fitting it too high or low. You obviously want to make sure you still have easy access to surrounding fixtures such as towel warmers or radiators. When you’ve confirmed where on the wall you’d like to install the unit, mark up the edges using a pencil.
If your bathroom vanities incorporate an open back to allow for the pipework, you can begin your installation work. If it has a closed back, you’ll have to cut holes to enable the pipes to fit into the bathroom vanity.
Step 3. Fitting the bathroom vanity to the wall
Double check your wall markings to make sure they are level. Ensure there’s no difference between the position of the pipes and the holes in the back of the bathroom vanity by positioning it against the wall. If everything aligns, you can start to fit the bathroom vanity.
Identify the wall studs prior to screwing the bathroom vanity into the wall. Drill into the studs and fit the unit to the wall, ensuring it is securely attached before installing the basin. After it has been fitted to the wall, check that it is perfectly level using a spirit level.
Step 4. Fitting the sink to the bathroom vanity
You’ll need to fit the sink faucet (more in our Ultimate Guide to Faucets) and waste before fitting the sink to your bathroom vanity, to ensure a far easier process.
Position and align the sink atop of the bathroom vanity. Apply silicone sealant to the gap between the bathroom vanity and the sink, in order to create a watertight seal that will assist the prevention of water damage.
The silicone sealant will take approximately 24 hours to set completely. You’re also required to seal the gap between the wall and the bathroom vanity.
Step 5. Check for leaks
After checking that all connections are secure, you can turn on the water supply to check for any leaks. Turn the water back on, run the faucet, and check the connections between the faucet, drain and pipework. If there are no leaks present and everything is secure, your bathroom vanity has been successfully installed. During the setting of the silicone sealing, avoid placing heavy objects on top of the unit.
