How to Install a Vessel Sink


Vessel sink faucets are very popular bathroom improvement hardware because they not only improve their appearance; they also improve user satisfaction. Vessel sinks may be made from any type of build material, but the value they offer users is what makes them highly sought after. With this sink type, you can create something new out of an existing structure or piece of furniture. If you are planning to shop for one but you are not so sure about how to go about installing it in your home, read on to learn how to do it.

Things to consider
  • Before you commence installation, check the vessel sink you want to install for special mounting instructions by the manufacturer.
  • If you are going to install an actual vessel sink faucet, install the faucet first before the sink. Installing the sink first will make it difficult to install the faucet afterward.
  • Drain holes are required on the vanity or dresser you’ve picked for the sink installation
  • Pay close attention to the location of the drain pipe and the height of the sink. (Don’t place it too high). 30-36 inches is fine.
  • Additional modification to the dresser or vanity may be required if it is not specifically suited for vessel sink faucets.

 

Installation instructions

Having a suitable drain fitting is very vital when installing vessel sink faucet. An incorrect one will either make the installation process difficult or impossible. Most fittings act as both the anchor(which holds the sink in place)  and the drain opening(for water outflow). Going for a sink fitting with an anchor and drain opening is preferable since installing such a fitting is not cumbersome.

On the other hand, if your sink has no overflow, you can only use a drain fitting that doesn’t have an overflow as well.

Vessel Sink Placement

Your first act in the installation process will be to position the sink on the furniture cabinet or countertop. A flat bottom sink is better placed on top of the countertop directly so as to allow it to align with the opening in the drain. If the sink comes with a mounting ring like most glass sinks, have, place it above the drain opening, then position the vessel and let it rest on the mounting ring.

Fix Drain Fitting

Drain fitting

To fix the drain fittings of your vessel sink faucets, you need to apply plumber putty to the drain flange's bottom surface. If your sink has a rubber or foam gasket, place the plumber putty against the flange's bottom surface.

After doing this, insert into the drain fitting a threaded tailpiece. Place it inside the drain opening and the countertop's cutout. Be careful when doing this to make sure it fits properly.

Below the vessel sink, apply your pipe joint to seal it. Slide it around the tailpiece and into the cutout countertop as much as possible. With the rubber seal in place,  thread the mounting nut and the friction ring into the drain tailpiece. Do make sure that you tighten the nut as much as you can to hold it in place. For better results, make use of a pipe wrench to make it tighter but don’t overdo it lest you damage the sink.

Note: Check alignment and lettering of the drain fitting to be sure that they are perfectly aligned. If they are, it means that it’s been properly installed.

Connect Drain Trap

With the sink drain in place, connect drain trap to drain fitting. Sizing is very important at this point. A 1 ¼ inch drain tailpiece will need a corresponding drain trap of 1 ½ with a reducer fitting.

A drain trap comprises a trap bend and a trap arm. The trap bend is fitted into the drain tailpiece while the arm connects half the trap bend to the opening of the branch drain located in the wall. To make connections, use slip washers and nuts.

Leak Testing

To conclude the process, you will have to check for leaks. Open the tap and let the water run through the sink. While water flows through, check under the sink to see if you spot any leakage. If you don't find any leaks, do not stop at that. Run water until it fills up all the way to the brim to do a proper water volume test.

If you notice any leaks around the nuts, making the nuts a little tighter will fix this, but if the leak is coming from the bottom, it means that the fitting was not properly positioned on the vessel sink faucet's bottom. Disassembling and reinstalling the sink all over again may be required.
