Fitting a drain to your vessel sink is no rocket science. There are six simple steps that you have to follow. We have provided in-depth information on how to do the task. So, happy fitting!

Step-1: Get the Right Utensils

Even before you start, the first and foremost step is ensuring that you have all the materials and equipment you need for the job. Probably, this is the only complicated part of the task, because you would need a good number of things! To make things easier, here is a list of the items you would need and their purpose.

Material Usage
(1) Pop-up Drain The most important drainage system for a sink is the pop-up. Once you have opened it, the stored water will be flushed through the drainage.
(2) Waterproof Putty (or Silicone Putty) & Plumbers Glue In order to attach the drainage or any other accessory to your sink, this is a piece of essential equipment.

Just like cement, these dry off and guarantee the item stays in place.

Now, it has to be waterproof as water can have negative effects. Also, you need plumbers glue to stick the plastic equipment and other stuff.

(3) Putty Gun/Knife/Cement Shovel By these, we mean a piece of equipment that you will be using to apply the putty. Now, the putty gun is the best choice.

Nevertheless, you can opt for anything that will allow you to do the job conveniently.

(4) Tape Measure/ Ruler In order to have the best fitting, measurements are the key! If you have the exact dimensions, then you will be able to install the vessel drain accurately.
(5) Pencil/ Marker/ Chalk Aside from the measuring utensils, you need to be able to mark the measurements. This is where these would come in handy.

We suggest that you opt for chalk and pencil.

(6) P-trap You need to make sure that your bathroom does not stink. And, for that, you need a p-trap!
(7) Attaching Tools like Wrench & Screwdrivers Apart from the glue and putty, you would need something to install the pipes and other stuff.

Most pipes require screws or bolts to ensure that they are firmly secured, and a wrench is the best option to tighten those small components.

(8) Leveling Tool These are for perfection! You would need them to confirm that the fitments are perfectly leveled.
(9) Cutting Tools (Hacksaw) Most of the time, you would need a cutting tool to make quick adjustments. For that, you would need something like a hacksaw.

Step-2: Select the Adequate Drain

Once you have everything you need, we can now move on to the next step. You can opt for a pop-up drain as well as a gride drain. Nonetheless, we suggest that you get the pop-up drain. Gride drains are okay; nevertheless, they are not as good as pop-up drains.

You see, pop-up drains are easier to install. Plus, they have a soft-touch feature, which allows you to open the drainage system with a single touch. Also, if you choose a pop-up drain, you will not have to be careful about the whole size (like in grid drains).

Again, these are not directly connected to the overflow. Therefore, the drainage is much more efficient.

Step-3: The Setup for the Sink

Now, you have the right drainage device (or contraption) and all the essential tools. So, let us get to work. Firstly, align the sink using the holes for the drain as your guide. Make sure that you are marking them as you do your work. Use chalk or pencil for this (if you do not have one around, a pen or marker will do the trick).

Next, flip the vessel and apply a bead of silicone (waterproof) putty. After that, place the vessel sink over those markings. You need to be careful while doing this task as the fittings have to be exactly in their desired place. Following its proper placement, let the putty dry!

If you have used chalk for the markings and are worried that they would make your job nasty, then we have a solution. Let them dry! Once dry, you can easily peel off the excess. Now, take your leveling tool to make sure that the sink has been placed correctly. After all these are done, let the putty dry completely.

Step-4: Installing the Drain

There are some models that come with a pre-fitted drain. But there are some that need an extra component. Now, going for the ones that have a pre-fitted system is much more effortless and efficient. Also, it costs much less.

Anyways, you have to make sure that the main drain has no connection to this, as that is the only way to prevent the overflowing completely. Connect it using the same methods in the previous step. However, here you would need to pass the drain through the vessel and into the vanity.

Before you pass it through the vanity, make sure to apply a layer of the sealant as that would make sure the item is properly secured in place. Furthermore, it reduces the chances of leakage.

Step-5: Attach the Faucet & Handles

Now that the drain is properly fixed, it is time that we connect the faucet and handles to it.

Installing it is not a very tricky task (as there is a particular mechanism to secure it firmly). Nonetheless, there is a little catch. You have to make sure that the hot and cold pipes are properly attached.

Step-6: Secure the Drain to the Main Plumbing Lines

It’s time that we take one step closer to the entire journey. Next, we will be connecting the vessel drain to the main plumbing line. For that, the first thing you need to do is make sure that the line is not too long. If it is, use a hack saw to make the adjustments.

After that, connect the entire contraption to the P-trap. (Make sure that you do not overtighten).

Step-7: Check

Turn the faucet on to see if the entire thing is working properly or not. Make sure there are no leaks or anything. Once everything is done successfully, you are good to use the vessel sink, and it will never overflow!
