When considering installing something like a vanity sink, you must always consider the amount of storage space that you will require, also physical size and design. Fitting a vanity cabinet and sink is great way to get more storage and countertop room in the bathroom. You can always seek professional advice from a company like Feltham Plumbers. On the vanity unit itself, the water feeds should be fitted with caps that are either soldered or glued, so you will have to cut them away when you have placed the vanity unit. Measure and note the water feed and drain plumbing and trace the positions onto the rear of the vanity unit. Cut out the hole for the vanity’s sink unit if required.

Place the vanity over the lines and up against the supporting wall. Check that the cabinet is setting level/square and secure it in place. A Feltham Plumber can supply and fit vanity units.

Method:
For the plumbing, you can now connect the spout, water valves and handles to the vanity sink unit and link the water supply ‘T’ and hose onto the spout. Connect the water supply pipes to the valves, as this will mean you don’t have to work from underneath later in the installation.

Spread some plumber’s putty around the drain fitting to form a seal and secure the fitting in the drain hole. Put a washer and slip nut on the bottom and tighten up the fitting. Fit the drain stopper coupling with its gasket so it lines up with the back of the sink unit.

Press the stopper’s slip arm through the sink and connect it to the coupling. Now, press the stopper fully open and do the arm up tight. Raise the sink up and sit it in the vanity cabinet. Use adhesive to fit a threaded adapter coupling onto the drain stub. Fit the trap and screw it to the adapter and the sink’s drain. Tighten up the sink water supply pipes to their shut-off valves. Very slowly open the shut-off, checking for leaks. Fill up the sink with water, check for leaks, especially around the drain. Drain the water and check the waste pipework joints. This will also put water in the trap to make sure there are no sewer gases.
Seal the sink rim.
