There are many reasons you might be in the market for a different bathroom sink. Perhaps it has started showing signs of wear and tear. Pulling out a bathroom sink that is chipped, cracked, or has simply gone out of style might be a time consuming process for an amateur, but once you get your basics straight it will not seem as daunting. This is a job you can do yourself. With the right tools and this guide you will be able to replace a bathroom sink.
Step 1 - Measure
To replace a bathroom sink, the first and foremost requirement is to get the measurements right. For starters measure the bathroom sink for its length, width, and depth. Measure the counter top to ascertain the dimensions of the area the bathroom sink is going to rest on.
Step 2 - Buy the Bathroom Sink
Replace the bathroom sink by buying a new one at your hardware store. Make sure to take the measurements along. The new bathroom sink measurement should match the old one or be larger. Note, if it is larger you will need to modify the counter to fit the new sink.
Step 3 - Turn Off the Water
Turn off the water supply to the sink before you replace the bathroom sink. You will have to remove faucet and drain, so no water can be in the system.
Step 4 - Disconnect the Plumbing
Dismantle the plumbing from the existing sink. Make sure the faucet is free of water before you remove it by turning it on and letting the accumulated water flow out.
Place a bucket under the P trap. This will catch the water in the P trap when the drain is disconnected. The drain will be removed by a combination of unscrewing and removing putty.
Step 5 - Remove the Clips
Look under the sink to locate clips, if any. These clips attach the sink to the counter top. Remove the clips.
Step 6 - Remove Sealant
Use a putty knife to release the grip of the sealant between the countertop and the sink's rim. The sink is now free to be removed from its slot. Gently lift the old sink out and put it aside.
Step 7 - Apply Silicone Sealant
Apply silicone sealant on the sink, and then place it into the countertop. When you replace the bathroom sink, make sure it rests firmly on the counter top. If excess silicone seeps out wipe it off with a damp cloth.
Step 8 - Connect the New Sink
The next step after you replace the bathroom sink is to connect the P trap and reinstall the faucet. Remember to caulk all edges to keep water from leaking.
Step 9 - Test the New Fitting
Turn the water supply on and let the water flow. Test the connections and the edges of the sink. There should not be any leaks.
