Bathroom Sink Installation Tutorial

When you want to replace your bathroom sink for any reason, you will need to find a new sink that meets your required dimensions. Once you find the sink you want, remove your old sink by turning off the water and then detaching the supply lines and pipes underneath the counter. Next, remove the caulking holding the sink tightly to the counter and any under-counter securing brackets if your sink has these as well. After this, the sink should lift out.

If you plan on reusing the faucet, separate the faucet from the sink by removing the plate underneath the sink and pulling the faucet and sink apart. Then, attach the old faucet to the new sink by reversing this step to get it attached to the new sink. If you plan on installing a new faucet, you can leave the old faucet attached to the old sink for now.

Then, set the new sink in place and attach the faucet if it isn’t already attached. Begin the process of reattaching supply lines and the S-trap. You may need to trim down the lines on the new sink if they are too long. You want a little bit of slack in the lines but not too much, or you could slow down water flow and increase the likelihood of leaks by making it more likely to get caught on items underneath the sink. Additionally, you may need to use an adaptor ring to change the size of the pipe if the sink uses a different sized pipe than what is located underneath your sink. Once everything is reattached, turn the water back on and test the sink. When doing leak testing, turn the water on high and check each connection with a flashlight. If you find any leaks, gently tighten up those connections using a towel and hand tightening or with light use of a wrench to avoid overtightening and breaking the line. Use Teflon tape, where necessary, to keep everything watertight. Once you can be sure that the sink is not leaking, run a line of caulk around the sink where it meets the counter, wiping away excess with a damp cloth. Allow it to dry for 24-hours before using the sink or cleaning around it.

Remember, a professional plumber installs sinks every day, so if you don’t feel confident installing your own sink, call a local plumber to come out and do the job. A licensed plumber will get the job done right the first time so you can avoid risking the potential of costly water damage from a leaking supply line or trap.
