Also known as entertainment, island, prep, or wet bar sinks,this is a smaller type than a typical kitchen sink. It is usually round or square. A bar sink simplifies the serving of alcoholic drinks both at home and in entertainment joints. This is because it has a faucet that enables quick washing of drinking glasses.

Additionally, this type of sink helps in cleaning spills caused by drinks on the bar. Therefore, in today's guide, you will learn about the installation process of a bar sink.

Let's start.

What Tools and Materials do You Require to Install a Bar Sink?

It would be best to have the following tools and materials ready before you begin installing your wet bar sink.
  • Paddle bit
  • Jigsaw
  • Channel-lock pliers
  • Washer
  • Faucet
  • Sink
  • Drain flange
  • Rubber gasket
  • Caulk
  • Nuts
  • Plumber's putty
  • Screw gun

If you have all these tools and materials ready, you can now go to the next section, where you will learn how to mount a bar sink.

7 Steps of Installing a Bar Sink:

Before you start mounting this sink on your bar, you must know where the waterline position is. This is to make it easy to install.

However, if the waterline is far from the position, you want to install the sink. Please begin with fixing the waterline for easy installation of the faucet.

If everything is in place, let's begin.

Step 1: Measure the Sink

Measuring the sink's dimension is vital in the installation process. This will guide you on the amount of space you will cut on your countertop.

Step 2: Cutting the Countertop

After you are done measuring the sink's dimension, it's now time to cut the countertop. Reduce the measurement by a half-inch to make the bar sink fit and prevent the sink from going through space.

When cutting the hole, make sure you use a paddle bit to drills the spots at the edges of the dimensions you have drawn. Then use a jigsaw to cut the countertop.

Step 3: Test

You need to place the sink on the hole you've cut to test if it fits appropriately. If you did it correctly and the sink fits appropriately. Remove it and go to the next step.

Step 4: Fix the Drain Flange

Now that you have confirmed that the sink fits,it's time to fix the drain flange.

Sink experts recommend that you set up the drain flange before placing the sink in its position.

So, using a plumber's putty, apply round the flange. This is to avert water spillage.

When you finish applying the putty, fix the drain flange into the sink's drain hole.

Step 5: Mount the Gasket and Sink

Also, mount the gasket while the sink is on the countertop. You need to follow the manufacturer's instructions when it comes to fixing the gasket. This is because setting the gasket differs depending on the sink's manufacturer.

After mounting the gasket,please attach the locking ring and fasten it using a channel lock pliers. Make sure it's tight enough to prevent any water leakage.

You are advised to avoid fixing the gasket after you have placed the sink in position. This will be challenging.

When you are done setting up the gasket, apply the caulk around the sink's edges (underneath) and place the sink into position. Using a dry cloth, clean the excess caulk from your bar.

Step 6: Faucet Installation

When you complete fixing the drainage fixtures, it's time to install the faucet.

Remove the faucet from the package. Then on the sink's hole, place the flange and gasket.

Before you mount the flange, check to ensure that the gasket didn't fall while removing it from the package.

Place the faucet body on the sinkhole through the flange and gasket.

When you are done, go underneath the sink and tighten the faucet. This process is done by the use of a mounting bracket and nut.

Fasten the faucet using a wrench. But make sure not to over fasten the faucet.

Now connect the waterline to the faucet. Before youjoin the waterline, please flush the waterline to remove any debris.

When connecting the waterline and the faucet, make sure you use two adjustable wrenches. One is to hold the copper lines, while the other is for tightening the connection to prevent water leakage.

Using two adjustable wrenches is to prevent you from twisting the faucet's copper lines.

Go back to your bar sink and turn on the faucet and check if everything is okay. Also, leave the water to flow and check if there's any leakage on the connected joints.

Note: You should install the drain flange and gasketbefore fixing the sink into position. This is to reduce the work involved in setting the while underneath the sink.

Step 7: Setting Up the Drainage

Lastly, connect the drainage system. All you have to do is fix the pipes as you will have to set the drain flange and gasket.

Great! These are all the steps you must follow to install your bar sink alone. This guide is for you who prefer DIY.

You can also hire a professional plumber to fix the sink professionally. I would recommend to consult with author for everything you need about sink plumbing. Hiring a plumber is advantageous as they come prepared with all tools and know-how to fix the sink properly.
