How to Install a Floor Sink

A floor sink is a great way to add an extra layer of protection to your kitchen or bathroom. Installing one is a relatively simple process, and in this blog post, we’ll show you how to do it. Floor sinks are available in various sizes and styles, so be sure to choose one that’s the right fit for your needs.

How to Install a Floor Sink

Once you’ve installed your floor sink, you can rest assured knowing that your floors are protected from accidental spills and leaks. A floor sink also makes a helpful addition to your workshop or garage, allowing you to wash up after messy projects without having to lug buckets of water back and forth.

In certain parts of the country, it’s not uncommon to find them in outdoor spaces such as patios and gardens. Floor sinks are usually found near appliances that stand around 36 inches tall. So, this article is for you. You will learn how to install a floor sink with just one simple trick!

Step to Follow on How to Install a Floor Sink

Step One: Mark the Sink Location

Before installing the sink, you must first locate where you want it to go. First, find the center of the floor diagonally across the room. Then, measure out from either side of this point 3 feet and mark two spots on either side of your measured line. These are the exact location for your floor sink’s legs.

If you have a preexisting sink in the same room, you can use it as a guide to determine the new sink’s size and shape. First, trace around the outside of the old sink onto some paper. Then, cut out this template and use it as a guide to mark where you want your new floor sink to go.

Then, take a look at the plumbing. You will need to know how far the drainage pipe extends from the wall so you can place the sink’s drain accordingly. Measure the distance from the wall to where the old drain line terminates, and make a small mark on your template.

Step Two: Prepare the Area

Now that you have the sink’s location marked, it’s time to prepare the space. First, remove any furniture or other objects in the way of the sink. If there is a tile floor, use a chisel and hammer to break away any grout around the old sink so you can remove it.

Using Chisel

Be careful not to damage the wall or floor when breaking away the tile. Instead, use a chisel to lightly score around the perimeter of the existing floor sink and use a hammer to tap down on the tile until it cracks. Then, you should be able to remove each piece easily by hand.

Remove any debris from your work area before proceeding. For example, sweep up sawdust left from the chiseling, wipe away any leftover residue from the tile removal, and vacuum up any dust or debris left on or around the floor. These steps should help you in learning how to install a floor sink.

Step Three: Install the Sink

Now it’s time to install your new floor sink. If you have a template, place it in the correct spot and use it as a guide to trace around the outside of the sink. If you don’t have a template, make sure the sink is facing the correct direction before tracing around it.

The drain hole should be towards the wall, with the faucet on the opposite side. Next, ensure you have included enough space to accommodate your drain line. Then, make any necessary adjustments before continuing with the installation. Once you are satisfied with the sink’s location and orientation, use a marker to trace around it onto the floor.

Install the Sink's Base

Then, find an angle grinder with a stone-cutting blade. Cut along the lines you have drawn on the floor to remove an area big enough for your sink’s base to sit on. If you are working in a carpeted room, it is best to cut the hole outside of the room, bring it inside and set it into place.

Step Four: Install the Sink’s Base

The sink’s base will need to be glued and screwed into place. Make sure the surface is clean and dry before applying a thin layer of silicone adhesive to the bottom of the sink. Please do not use too much adhesive, or it will seep out from under the sink and cause problems later on.

Next, carefully set the sink into place and press down on it until it is level. If you are working in a carpeted room, it is best to have someone help you hold the sink in place while you attach it. Once the sink is secure, use a drill and screwdriver to connect the base to the floor.

Be sure to use screws that are long enough to go through the base and into the floor to ensure a secure fit. Do not attach the faucet at this time; you will do that after setting up and connecting the sink’s drain line.

Step Five: Install Drain Line

To connect the new sink’s drain line to your drainage system, ensure it is securely supported. It would help if you supported both ends of the pipe as you maneuver it through the hole in your floor. Secure both ends with sturdy J clamps, and attach the tailpiece adapter to one end of the pipe before proceeding.

Your Drainage System

Next, thread a washer and nut onto either side of the tailpiece that will be secured to the sink. Then, apply the plumber’s putty around the edge of the sink’s drain hole and set the sink in place. Next, push the drain line up through the hole until it is seated firmly on the putty.

Tighten the nut on the tailpiece to attach the drain line firmly to the new sink. Check underneath the sink and ensure the connection is secure and does not leak. This information will help you learn how to install a floor sink.

Step Six: Maintain and Clean the Sink

Once your new sink is installed, be sure to keep it clean and dry. After each use, wipe it down with a damp cloth and apply a layer of silicone sealant around the drain hole every few months to prevent water damage. If you have any problems with the sink, or if it starts to leak, contact a plumber for assistance.

Now that your floor sink is installed, you can enjoy the convenience and functionality it provides. Be sure to keep it clean and dry to prevent any water damage, and call a plumber if you have any issues with it.
