Proper Installation for Bathroom Vessel Sinks

If you’re new to vessel sink installation, you need to know how to properly install one in your bathroom vanity. The type of contemporary bathroom vanity you purchase will dictate how you install your vessel sink.


As far as current modern bathroom design and styles go, the bathroom sink of choice these days is the vessel sink.  A vessel sink is a sink that rests partially or completely above the surface on the vanity.  It is not sunken under the counter top. Vessel sinks are their own separate unit and need to be installed a certain way.

If you’re new to vessel sink installation, you need to know how to properly install one in your bathroom vanity.  The type of contemporary bathroom vanity you purchase will dictate how you install your vessel sink.  Some vanities are designed specifically for partially submerged sinks while others are constructed to house an above counter sink.  With those types of vanities, you are pretty restricted on where and how you install your sink.  However, some vanities allow you to select the positioning of your sink.  In those cases, here’s what you need to do.

Note: It’s better to install the sink and faucet at the same time.  It will allow you to make all necessary alterations prior to installing either component.

Planning the Layout

Before you install the sink you need to position the vanity in your bathroom.  It’s better to situate the vanity as best you can before you start making holes in the counter top; however you don’t need to mount it to the wall and floor just yet.  Give yourself some room to install the sink.

If there are no pre-drilled faucet holes, decide where you want the faucet to be in relation to the sink.  Once you’ve decided on a vessel sink/faucet layout, make a template of the counter top (cardboard will work best for your template). Then, mark the appropriate location for the sink drainage and faucet holes.  Draw everything out and make any necessary changes prior to drilling and cutting.  Like they always say, measure twice, cut once.  Just before you make the cut, you may want to reassure yourself of the measurements by placing the sink and faucet over their chosen holes. This will help you to get a good idea of how everything will come together once in the holes are cut and everything is in place.


Making the Cut

After you’ve created and marked your template, lay it out over the counter top and make the necessary marks directly onto the counter top. Be sure to take an accurate measurement of the hole sizes needed for your sink and faucet.  The best way to do this is to cut out your final marks on your template so you can draw directly onto the vanity.  After you’ve marked the vanity top, make the necessary cuts with a drill using a Hole Saw Drill Bit.  The drill will give you the accuracy you need to make a more precise cut.  As for the screw holes, grab your drill and pre-drill them with a standard drill bit.  This will make fastening the faucet to your vanity much easier. Once the cuts have been made, take your sink and faucet again, once more, and place them onto the vanity to make sure everything lines up.  Make any necessary alterations to your cuts until everything lines up perfectly.

Securing the Sink

Once the cuts have been made and verified, it’s time to secure the sink and faucet to your bathroom vanity.  All you need to do is position the sink, and caulk and tighten everything down.  If you’re dealing with a glass vessel sink, you need to place a connecting ring between the sink and the counter.  Silicone works as a great cushion for glass vessel sinks, but we recommend a connecting ring as a preventative measure on future wear and tear.

When it comes to modern bathroom sink design, you have a wide array of options.  You can mount sinks directly on top of vanities, partially submerge them, or even have the faucet mounted to the wall rather than the vanity itself.  But regardless of the direction you decide to go with your new modern bathroom sink, you need to know how to properly install it.  The best solution is to hire a professional who has experience installing such sinks.  As proficient as you may think you are in making home repairs, sometimes it’s just easier and less troublesome to have a professional do it.  We offer a wide selection of Bathroom Vessl Sinks, Fixtures, and Accessories at great affordable prices.  From modern bathroom sinks to state-of-the-art faucets, World of Sinks has the furnishings you need to transform your bathroom.

As you begin the installation of your Bathroom Vessel Faucet, remember that the Vessel Faucet is not the same as those faucets that we are used to.

Begin by making sure that the hole to be drilled is measured correctly to your wants or needs.  The Vessel Faucets tend to function most efficiently when they are about a ½” from the sink.  You should measure accordingly to assure the faucet is not too far from the sink.  Each faucet design is different and those differences should be taken into consideration when deciding on the placement of the faucet.

After the measurements have been accurately taken and the hole drilled, the faucet is now ready to be installed. There is a simple solution for installation on these new designs of vessel faucets.  The water supply line that come with the faucets are designed to fit well with the the standard of plumbing we already live with.  If by chance the water supply lines do not reach your water supply valve, you may get extension supply lines.  The supply lines that work best are the kitchen style supply lines measuring 1/2” female to 3/4” female.  You then need to double sided male nipples measuring 1/2” to 1/2”. These will allow you to connect the to different water supply lines together with ease.  Be sure to use Teflon Plumbers Tape when joining any threads.  This will allow for a better seal and a long-lasting faucet and sink with no leakage.  An important point to remember!!! When securing the water supply lines to the faucet, to only hand tighten them.  They are not designed to be torqued with any type of wrench or other tool.  Using anything other than your own strength to tighten them can cause stripping of the threads and other damage.
