Here’s What You’ll Need To Replace Your Bathroom Basin 

Whether you have a drop-in sink, inset basin or above counter basin, the processes are fairly similar. Before installing your bathroom sink, you will need to prepare several things first. Preparing the tools and materials before you start will help the project run smoothly. Here is what you need:


  • Wrenches 
  • Socket set 
  • Screwdriver set 
  • Bucket 
  • Towel 
  • Sharp blade
  • Pencil 


  • Silicone caulk 
  • Flexible hose 
  • Single-lever mixer or tap set 
  • PTFE thread tape 


The 5 Step Process To Removing Your Bathroom Basin

Alright, granted you’ve already gathered the tools and materials needed for the job, it’s time to get into the itty-gritty side of things. Here is the process on how to remove your bathroom basin:

  • Turn The Water Mains Off!: Please, for the sake of your mental health, wallet and dignity, turn the water mains off before you start any plumbing work. One accident or wrong decision could be extremely costly because your water pipes are still live!
  • Clear The Taps: Once the water mains are off, open up your taps just to clear any excess water laying about. This isn’t a major, but will help you keep mess to a minimum.
  • Place Your Bucket and Towel: Now, place your bucket and towel in a strategic place you think there will be drips and leaks. Again, this is more for keeping mess to a minimum. 
  • Start Disconnecting Your Taps and Pipes: Now that mess prevention is in place, you can start detaching all of the plumbing from under your sink. 
  • Remove The Bathroom Basin: Once everything is detached, you can start cutting around the basin with your blade. Then lift up the basin and remove it.


The 7 Step Process To Installing Your Bathroom Basin 

Now that you have prepared yourself, you’ve got your tools, you’ve removed the old basin (granted you needed to), it’s time to install the new one. Hopefully you already have a new basin ready, but if you don’t, you can get one here. This is the process on how to install your bathroom basin:

  • Measure and Measure Again: Measure twice, cut once. Or in this case, glue/install once. It’s an ancient proverb that is rather overused, but for a good reason. Make sure you measure and mark where the new basin needs to go.
  • Glue ‘er Down: Once you have measured, and tested you like the sink in the position it’s in. You can put some silicone caulk around the bottom lip of the basin. Then, put it in place!
  • Install The Faucet: Now that the sink is in place, you can install the faucet. Screw in all the parts required. 
  • Install The Drain Kit: Now the faucet and sink are in place, you can connect the pipes that will drain your water.
  • Connect The Water Supply Lines: Now, you can comfortably connect the water supply lines.
  • Clean-Up and Final Touches: Wipe away any mess and if you need, apply silicone caulk around any areas of the sink to make the fit nice and crisp. Oh, but leave the bucket and towel under the sink until the next step!
  • Turn The Water Mains On!: This is the last step! Now you can turn the water mains back on and test your taps. You leave the bucket and towel under the sink for this incase there is any leaking. If there is none, run the taps for a good minute or so, then your sink is all ready!

Do You Need A Plumber To Install Your Bathroom Sink?

The short answer, no. You do not need a plumber to install your bathroom basin/sink. You only need an accredited plumber when you are dealing with sewage/wastewater or drinking water supplies. You would also need a plumber or registered builder if you were doing building work with a value greater than $20,000. Don’t worry, your bathroom sink won’t cost that much. 

However, even though you don’t need a plumber, if you think installing your bathroom sink is too difficult and out of your skill level, or you are short of time, there’s nothing wrong with hiring one! Using a plumber is a sure-fire way to make sure your installation runs smoothly, it will just cost a bit more.
