How to Install a Counter-Top Vessel Sink
In the course of remodeling a bathroom, if a new vanity, counter-top, and faucet have already been installed. It may be time to install a vessel sink. This is a relatively simple task. Nevertheless, it requires some planning ahead, as well as attention to detail.
The first step is to decide on the particular 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 to choose a vessel sink that will work with the installed faucet. Looks are just as important as size.
Next, determine whether the vessel sink should be a counter-top vessel sink or a recessed vessel sink. The counter-top 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. When planning on installing a glass or copper vessel sink also invest in a mounting ring (these are sometimes sold with the vessel sink itself).
For a counter-top vessel sink, coat the contact patches of the sink in a very strong silicone adhesive gel, or some other strong adhesive. The "contact patches" are the parts of the vessel sink that will come into direct contact with the sink. 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 drain opening. Be careful; accuracy is important as removing a vessel sink after using a very strong adhesive without difficulty is impossible. Once the sink is in place, insert the drain through the drain opening. Make sure it fits! Now, wipe up excess adhesive around the base. When the adhesive has dried a silicone caulk around the base can enhance the look and prevent any untoward spills from leaking under the counter-top.
Pretty simple. That is all there is to it! The vessel sink will be supported by the adhesive, the drain, and its own weight.
