Installing a Drop-In Bathroom Sink

In this video, it shows you the average Joes can do a simple task of replacing a drop-in bathroom sink.  When I moved into my home just over a year ago, my master bath has a double sink vanity with bisque sinks that I have never liked.  The toilet is white as well as the tub and I would love for them to match.  Watching this, I might just have to tackle this task and save us some extra money.  Drop in sinks are not that expensive as compared to replacing the whole vanity.  If you want to go with a different look, start small.  Remember, when removing the sink from the top, you may have to try pushing it out from the bottom as he did.  Make sure you test it out and make sure it fits before sealing it in place.  Also make sure that it is lined up properly.


We’re going to be replacing our bathroom sink. We’ve noticed over time that this basin is starting to rust. They used enamel over the top of it and it’s just getting kind of ugly. So I looked it up and the sink’s anywhere from forty to eighty dollars. So what we’re going to do is go ahead and remove this sink and to start doing that, remove the clips on the underside. So we cleaned out the underside of the sink and these clips just unscrew and come out. Then I also turned the water off at the valves, both sides, and put a towel down. It’s going to leak a little bit when I pull this out. So then I unhooked the water to the faucet so it’s all disconnected and now it’s just a matter of popping the sink out. I think it’s held in here with a little bit of silicone under the rim. So we’ll get to that next.

So the next step is to break the seal on the sink that’s holding it to the counter-top. They usually put some silicone sealant around the outside before they drop it in. One way to do that is to use a knife, but you have to be pretty careful not to scar up the surface of the counter. So keep the knife blade as flat as possible and slide it into and underneath the sink and pull it along to break that seal. Now that I’ve broken the seal it should just pop right out. If you have a problem doing so, there may be a clip you forgot to unscrew so you can push it from the bottom.

What we’ll do is re-use the faucet and the drain and just replace this ceramic sink. Take the new sink and try it on for size. Make sure it will fit before you go putting silicone on it to put it in place.
Take the P-trap from the drain and clean it out real well since we’ll be reusing it. Next step is to put a bead of caulk around the outside of the sink. Actually it’s silicone. Okay now it’s time to set it in place. I’m going to push it down, make sure it’s good in place and then wipe the existing caulking away that squeezed out with a paper towel. The silicone helps to keep it so no water gets underneath it. You want to practice putting the sink in a few times before you do it with the caulking. A few dry runs, make sure you get it in the right place.

Let the sink set in place so the silicone has time to dry. And then it is a matter of hooking up the water lines and the drain pipe. We just reused the existing lines, hooked everything back up, and then turned it on and checked the leaks.
