How to Replace a Bathroom Sink – Step by Step

Updated: January 2019

Remodelling your bathroom is a DIY project that anyone can take on.

To replace your bathroom sink, you’ll need a pipe wrench, slip joint pliers, basin wrench, silicone caulking and plumbing sockets.

 

Step 1: Turn off your water supply valve, or your main water supply.

 

Step 2: Remove the old sink by disconnecting all of the supply and drain lines using the your pliers or a wrench. Slide the edge of a putty knife around the outside of the sink to loosen the caulk that connects it to the counter. Lift the sink out of the hole.

 

Step 3: Use your new sink template to create an opening that will fit your new sink.

 

Step 4: Mount the sink by lining the underside edge with silicone and setting the sink into the hole. If the silicone is pushed out to where you can see it, clean it up or smooth it into a line.

 

Step 5: Secure the sink with connective clips that are provided with your new sink. These will hold the sink in place.

 

Step 6: Install the faucet by screwing the assembly into the sink or the counter top.

 

Step 7: Install the tailpiece and drain by screwing it into the appropriate place underneath the sink.

 

Step 8: Connect the water supply lines to the underside of the faucet. If your sink doesn’t match your valves, you can get the correct valves from your local hardware store.
