How To Install a Vessel Sink
So you're remodeling your bathroom, and you've already installed your new vanity, your countertops, and your faucet. Now it's time to install your vessel sink. This is a relatively simple task, though it does take some planning ahead of time, as well as attention to detail.
First, you have to decide on a vessel sink. There are two basic styles of vessel sinks: bowl-shaped sinks with a round bottom, and flat-bottomed sinks. It is also important that you choose a vessel sink that will work with your faucet. Size is just as important as looks.
Next, you have to determine whether you want your vessel sink to be a countertop sink or a recessed sink. The countertop installation technique is the most popular and versatile; the recessed style only works well with perfectly rounded vessel sinks made of wood, stone, or copper. Trying to install a glass recessed vessel sink, for example, will lead to scratches as well as unsightly adhesive smears. If you plan on installing a glass or copper vessel sink, you should also invest in a mounting ring.
For the purposes of this article, we will only discuss the installation of a countertop vessel sink:
Coat the contact patches of the sink in a very strong silicone adhesive gel, or some other strong countertop adhesive. The “contact patches” are the parts of the vessel sink that will come into direct contact with the countertop; for a square-bottom vessel, apply adhesive around the whole perimeter of the base. For a round bottom, apply a small amount of adhesive at the bottom of the bowl. Try to avoid applying adhesive very close to the edge, as this will smudge.
Now, position the sink drain hole over the countertop drain opening. Be careful; accuracy is important as you’re dealing with a very strong adhesive. Once the sink is in place, insert the drain through the drain opening. Make sure it fits! Now, wipe up any excess adhesive around the base.
That's it! Your vessel sink will be held in place by the adhesive, the drain, and its own weight.
