How to Install a Pedestal Sink

How to Install a Pedestal Sink

Give your bathroom style and more room with
a pedestal sink. Before you start, check the installation instructions
for support, and plumbing requirements. Keep in mind you might need to reroute plumbing. To remove your old vanity, turn off the water
supply and turn on the faucet to relieve pressure in the lines.
Loosen the nuts to remove the drain pipes, and disconnect the water lines from the valves.
Cut the sealant along the backsplash and remove. If your vanity is secured to the wall, separate
the top from the vanity with a putty knife, lift it off and back out the screws.
The vanity should now pull out. With the old vanity out you can make plumbing
repairs – such as moving the supply lines and drain. Consider installing new plumbing
since it will be visible. Some pedestal sinks require a support board
behind the finished wall for extra strength. To install, mark the sink height on the wall,
cut out part of the wallboard and studs, and install the support board with screws. Then
repair the wall surface. This is an ideal time to paint, install wall
tile or new flooring. To install the new pedestal sink, mark the
centerline on the wall and floor. Then make a mark 10 inches from the wall– accounting
for the baseboard. Position the pedestal on the mark, and set the sink tight against the
wall, check for level and adjust the pedestal as needed. Mark the sink’s anchor holes on the wall
and the pedestal hole on the floor. Move the sink and pedestal aside, and drill the three
holes. Next, install hanger bolts in the wall – leaving
about 1 inch extending from the wall. Secure the pedestal to the floor with a lag
bolt and washer. Don’t over tighten. Attach your faucet and drain before setting
the sink bowl in place. Now position it over the hanger bolts, level
it, and secure it with cap nuts and washers. Again, don’t over tighten. Reconnect the drain and water supply, and
check for leaks. Consider adding a new mirror and lighting
fixture to match the look of your new sink. Want more great ideas and how tos? Go to

  1. A pedestal sink is the space-saving star of a small bath. Find out how to install one and reveal in the roominess.

  2. A nice simple video to start with. And yes, you do offer suggestions for other items to sell. I expect that from a retail store. And of course, my wife and I always are looking for compatible accessories when purchasing a product. Thus the matching bathroom mirror to go with the pedestal sink we purchased.

  3. 0:00 No, DON'T install a pedestal sink. The pedestal is an obstruction and you won't be able to tighten the pipes properly, and you'll have constant leaks. Stick to the vanity/bracket basin

  4. can the sink rest on the pedestal and being screwed to the plasterboard wall with anchor bolts to prevent it moving sideways?

  5. Would have been nice to see the finished project at a height other than 7 or 8 feet tall. How does the finished plumbing look people?

  6. You totally skipped over securing the pedestal to the floor!
    I'm trying to repair pipes under one, and I can't figure out how to remove the pedestal.

  7. My floor is porcelain tile. The plumber secured the pedestal to the tile with some sort of black mastic goo that he got all over the bathroom. He also cracked the pedestal and tried to hide it by gluing that back together. Everything thing was good to go in a couple months and that plumber will never darken my door again but putting this thing in on tile is a big deal and rerouting pipes? Forget about it.

  8. I wish it were this easy. We have a tiny vanity/basin combo and the porcelain basin broke when a glass jar was dropped in it. I thought a pedestal sink would be a nice change and not much more will fit in our tiny bathroom other than the same thing we have. But this is more complicated than my skills can endure.

  9. Really? A wood bathroom floor? This is essentially a useless guide for the vast majority of bathrooms. I have tile, like most do, and a simple lag bolt doesn't just screw into tile. So time to look elsewhere.

  10. Thanks. I have a few more hours of demo work and it'll be time to start the fun portion of the project – putting the new bathroom back together. Very informative and helpful video.
