A pedestal sink can give a bathroom a more elegant look. It is a type of sink that is attached to the wall. It doesn’t need a pedestal to support it. Here is how to remove pedestal sink.
When the sink gets installed, it gets attached to the wall, and the pedestal goes once the plumbing has already been completed. This means you can take the pedestal out without taking the sink or plumbing out.
Removing the Pedestal Sink
Pedestal sinks can be a challenge to work on because the plumbing and tubing are hidden behind the pedestal. This makes it difficult to get to and fix any problems that may occur.
If you are planning to remove your sink by yourself, make sure you have help. The process of taking it apart is not difficult, but it will be harder to take the sink off if you don’t have someone to help you.
The pedestal is attached to the sink by a notch on the bottom of the sink and is held in place by two bolts. The sink is attached to the studs. After completing the plumbing for the sink, the pedestal is slid into position and then bolted to the floor.
To uninstall the pedestal, reverse the installation procedure. This means removing the bolts, securing it to the floor using a socket wrench, and then sliding the pedestal forward until it’s free from the sink. You may need to cut through a bead of caulk, which will be around the edge of the pedestal base.
It’s best to be prepared in advance and have the tools you need at hand to complete this job without any problems. For this project, you will require the following supplies.
1. Turn off Both Water Supply Lines
Removing your pedestal sink will require you to first turn the water supply off. This is important so that you can work without water shooting in all directions once the sink is removed from its position.
2. Disconnect both Water Supply Lines
The water is supplied via two hoses that are attached to the sink. It’s a good idea to place an empty bucket right below the hose before unscrewing the connection using a pair of pliers in case any water leaks out.
3. Disconnect the P-trap at the Wall
Before removing the pedestal sink, loosen and release the p-trap. Unscrew the nut that is holding it in place. If you can’t unwind it by hand, then use a pair of adjustable pliers. After unscrewing the nut, take it out of the wall.
Note: Before working on the nut, place a bucket under the P-trap. This will catch the water that will come out when you remove the trap. Unscrew the nut that holds the P-trap using a set of pliers.
4. Cut the Silicone Seal or Caulk Around the Sink and Pedestal
A pedestal sink should have silicone along the edge where it meets the wall to prevent water from running down the wall, as well as around the pedestal at the base. To remove the sink and pedestal, cut out all the silicone or caulk with a sharp knife.
5. Remove Water Supply Lines
Remove the water supply lines from the faucet. Unscrew the nuts that hold the faucets to the sink and place them to one side.
6. With all the Connections Loosened, Remove the Sink
In order to release the sink from the floor, you will be required to undo the mounting bolts that hold the sink in place. Ask someone to assist you by holding the sink while you undo the nuts. Proceed to remove the drainage system from the sink. If you’re going to reuse the same hardware, you can clean out the pipes before installing them back in the new sink.
7. Remove the Pedestal from the Base
Only remove the pedestal if you are replacing it with a new pedestal or want to remove it all together.
Remove the bolts that hold the pedestal to the base of the floor. These may have rusted in place, so some WD40 or grease will make it easier to undo the nuts.
If you are replacing the pedestal with a new one, then just put the new pedestal in place and screw it in using the bolts provided.
8. Measure from the Door Jamb or the End of the Wall to the Center of the Drain
Measure and mark the distance from the wall to the front of the pedestal on the floor and on the pedestal itself. This will serve as a reference point when installing your new sink. When you’re ready, place the sink against the wall and check that it is level before securing it in place.
9. Initialize P-trap and Elbow in Place
You could place the P-trap and elbow in place before installing the new sink, but you don’t need to tighten them yet.
If you are using a new drain, measure and cut the new drain to match where the elbow is located. Use pipe dope or plumber’s tape to reconnect any male connections on the drain.
10. Install the New Sink
Set the basin on the pedestal and ensure it is flush against the wall. To finish this project, you will need help. Have someone adjust the pedestal, so it is level and push the basin against it. If your floor is not level, you might need to use a shim to make the pedestal even.
A wood shim will work, and then you can break off the extra wood. You can use any hard material, but place it from the inside of the pedestal so people can’t see it from the outside.
11. Mark Mounting Holes
Mark the location of the new mounting holes on the sink. Remove the sink. Test the new location for the mounting block with a nail. If it misses the old mounting block, you can use hollow wall anchors.
Attach the sink to the wall. If it is not level, use shims to adjust it. If the pedestal can be attached to the floor, do that now.
12. Attach the Faucets
To install the faucet to the new sink, reverse the steps you took to disassemble it from the old sink. Check instructions to see if you need putty, as some faucets are sealed and do not need a plumber’s putty, while some others do.
13. Install the Pop-Up-Drain
Putty is required to install the pop-up drain. Roll a wad of putty into a long, thin snake that is 3/4″ wide. Wrap it around the pop-up drain and under the flange. Place the drain into the basin hole. Tighten the gasket and washer onto the drain from under the basin.
Finish tightening with pliers. Remove any extra putty with your finger. Clean up any residue with a paper towel or sponge.
14. Attach Water Supply and P-Trap
Connect the water supply to the P-trap and tighten it (but not too tight). Turn on the water and test it to see if there are any leaks.
Close the stopper, so the water doesn’t drain out. Fill up the basin part way and let it go to check for leaks in the drain system.
To sum it up, there are a few things you need to think about. If you are replacing your sink, the water supply tubes that were mounted on the old sink might not match up to the location of the new or old faucet. If this is the case, you can use a flexible hose instead.
Measure the distance between the faucet and where you want to connect the water supply, add two extra inches to the length, and then buy a hose that is that length or close to it. Trying to use the old rods in the new place won’t work. You can crimp the rod, but you’ll still have to buy new hoses.
You will also need to put some caulk (silicone) on the edge where the sink meets the wall. This will help keep water from getting behind the sink and damaging the wall. Use bathroom caulk for this.
