Without the perfect sink, countertop and countertop, your bathroom simply isn’t going to function smoothly and look its best. In fact, while the shower or bath may be the centrepiece, the bathroom vanity is the heart of your favourite room in the house – where you wash your hands, do your hair and make-up, brush your teeth and get ready for the day. Installing a vanity, however, is quite tricky – especially if you also need to know how to install bathroom vanity plumbing.
For its functionality and style, the foundation of this essential part of your bathroom is the vanity plumbing. Unfortunately, installing a vanity isn’t as easy as it sounds, involving:
- Water supply lines
- Drainage pipes
- Shut-off valves
- Overflow drain & more.
And if that all sounds complicated, knowing how to install a bathroom vanity is even trickier. And even if you think you can install a bathroom vanity yourself, strict Australian and Queensland plumbing regulations require that only licensed plumbers can do your bathroom vanity plumbing. That’s because it requires special tools but also a high level of skill and knowledge to get the job done safely, properly, and to the required standards.
Still wondering how to install bathroom vanity plumbing? Our local plumbers in Brisbane and Gold Coast certainly installed a great deal of them all over the region. Remember, it’s a complex task that needs to be carried out just right to avoid leaks and other problems. Now let’s get into it:
1. Turn off the water
It’s a simple matter of locating the shut-off valve and turning it fully to the off position.
2. Remove the vanity
Assuming you’re removing an old, outdated vanity and replacing it with a new and modern one, you’ll need to completely take out the old unit. Start by turning off the hot and cold water valves under the sink, and using a wrench to remove the water supply lines.
Then it’s a matter of taking out the sink from the top of the vanity, as well as the screws that may be holding the unit to the wall.
3. Install the taps
Next, you’ll be installing the taps onto the new sink – which is done before the new sink is installed onto the vanity itself.
4. Install the drain
The drain assembly is inserted through the drain hole of the sink. It’s then attached to the underside of the sink with the nuts that are normally included in the bathroom vanity package. Finish this part of the job by applying the plumber’s putty around the edge of the drain, in order to create a tight seal and prevent leaks.
5. Install the sink
Next up, as mentioned in Step 3, we’ll be installing the sink onto the vanity. You’ll need to ensure the taps and drain are perfectly aligned with the vanity top’s holes. It’s then fully secured using the clips or mounting hardware that the vanity manufacturer has provided.
6. Install the P-trap
One end of the P-trap is attached to the drain outlet on the sink, and the other end is connected to the waste pipe. To do this, you’ll be using a mechanical compression fitting, which is designed specifically to connect two pipes together with a watertight seal.
7. Connect the water supply lines
You’re almost there! For this step, you’ll need a wrench to attach the water supply lines to the hot and cold water valves underneath the sink. Tighten the connections so they create a watertight seal, but not so tight as to damage the fittings themselves. As a general rule, hand-tighten and then another half-turn.
8. Test for leaks
Switch the water supply back on and carefully check for leaks.
9. Attach to the wall
Finish the job by completely attaching the entire bathroom vanity to the wall with the supplied mounting hardware.
