How to Install a Pedestal Sink Yourself

By Samantha Hager


As a homeowner, it can be a gratifying experience to install things yourself and also help save costs overall. One of key ways you can save on expenses is by installing household items through a DIY process.

Certain bathroom renovation projects are not that tough to tackle on your own and can be well worth the investment. For instance, one of the most commonly exchanged elements of a bathroom is the pedestal sink. In this guide, we give you a step-by-step overview of how to install the sink and transform your bathroom yourself (and at half the cost).

What Is a Pedestal Sink?

Unlike modern sinks, pedestal sinks are comprised of two pieces: the sink basin and the pedestal itself. For years, these pedestal sinks were found in every bathroom across America but, as trends changed, they began to become obsolete.

With new vintage styles becoming more popular, these sinks have made a full comeback. The most enticing aspect of these sinks, however, has nothing to do with fashion but rather space. By getting rid of the bulky vanity cabinet once found in bathrooms everywhere, homeowners have been able to add more space to their half baths and keep in touch with the latest trends in the process.

How to Install a Pedestal Sink

Now that you know more about this retro renovation trend, it’s time to review how to install one for yourself and the tools and materials you will need to do so.

Tools and Materials Needed

  • Drywall Repair Tool Set
  • Adjustable Wrench
  • Screwdriver Set
  • Hand Saw
  • Plier Set
  • Standard Level
  • Power Drill
  • Trap Pipe Fitting
  • Sink Faucet
  • Plywood
  • Drywall Screws
  • Drywall Sheets
  • Paint
  • Paint Tools
  • Patching and Repair Kit
  • Caulk/ Sealant

With these tools and materials in hand, all that’s left is to install the sink according to the directions below.

Install the Mounting Brace

When it comes to this step, it’s important to review the manufacturer’s guidelines for locating the sink brace (a material needed to keep your sink sturdy and in place over time, similar to a clamp). Then, follow these steps: 

  1. Cut a hole in the wall that is the perfect size stud-to-stud
  2. Cut a piece of plywood to fit that hole
  3. Attach the brace with angle-driven screws (screws are driven in at an angle)
  4. Patch the hole
  5. Sand it out and paint it to match the wall again

Attach the Mounting Bracket

To attach the mounting bracket to the wall, follow these steps:

  1. Assemble the sink up against the wall and see where it needs to be attached
  2. Anchor the bracket by driving screws into the plywood
  3. Make sure that it stays level throughout this process (use your level to do this)

Set the Sink in Place

With the brace and bracket set up, it’s time to set the sink in place. Please note the installation of these elements will vary depending on the sink, so be sure to also pay close attention to the sink’s specific manual and follow these steps:

  1. Install the faucet
  2. Install most of the trap
  3. Install the pop-up assembly
  4. Set it onto the bracket
  5. Make sure you have the right amount of space for the pedestal
  6. If not, reset the bracket accordingly

Attach the Plumbing

Follow these steps to ensure proper plumbing:

  1. Connect the trap and supply lines according to the instructions given with the sink
  2. Check for leaks by turning on the water and waiting

Install Pedestal and Bolt it to the Floor

Now that you have all the parts that make a standard sink in place, it’s time to install the pedestal. As long as you have made sure it fits properly throughout this process, it should be a fairly simple installation. Keep in mind if it doesn’t fit in place easily, you will have to go back to remove the plumbing and sink, and redo the entire process until it’s right.

Once the pedestal is set in its rightful place, simply bolt it to the floor to ensure it doesn’t move anywhere and cause leaks.

Connect the Water Basin to the Wall

Lastly, it’s time to connect the sink basin to the wall. Although not every pedestal sink requires this, some will and it is important that you follow these steps in that situation:

  1. Screw the basin to the wall
  2. Be careful not to screw too tight and strip the screws (this will make it easier to remove later if needed)

With all of this done, congratulations. You have your very own pedestal sink. Now, you can move on to the next DIY project feeling proud, accomplished, and excited for more budget-friendly and involved home renovations.

How Much Money Will You Save Doing This Yourself?

Although it’s fairly obvious that DIY renovations will save you money, the question is how much money could a DIY pedestal sink really save? For this, let’s look at typical renovation costs.

The average cost of a DIY bathroom renovation is anywhere between $75 to $100 per square foot, while hiring a crew costs roughly $225 per square foot. Some owners opt to have a DIY consultation when remodeling which costs roughly $300, while a renovation crew often charges $200 per day and takes nearly 5 days to complete a full bathroom remodel. This alone could save you roughly $700 in bathroom renovation costs.

In the end, a day’s work can leave you with a  space-saving, beautiful pedestal sink of your own and hundreds of dollars still in your pocket.
