How to Install a Pedestal Sink · Step 1 of 8
In this video
Before starting any work, prepare the area under the sink. Begin by shutting off the hot and cold water supply valves, typically by turning them clockwise. Place a bucket or container underneath the plumbing to catch any water that will drain from the lines. Open the existing faucet to release any pressure and drain the remaining water. Finally, use an adjustable wrench to disconnect the hot and cold water supply lines from the shutoff valves.
Goal: Shut off water and disconnect supply lines
- If you cannot find or operate the shutoff valves under the sink, you will need to shut off the main water valve for the entire house.
- Keep a towel handy to clean up any spills immediately.

FAQs
Do I really need all the specific tools listed, like the Hilti drill and Zircon stud finder?
For secure and accurate installation, a stud finder is highly recommended to ensure the basin is mounted to wall studs, preventing wobbling. While the Hilti drill is powerful, any corded hammer drill with appropriate masonry bits can work for drilling into tile or plaster if studs aren't accessible or for floor mounting, but ensure it's capable of making clean holes.
What's the most critical safety precaution to take before starting this pedestal sink installation?
The most critical step is to turn off the water supply to the entire house or at least the bathroom you're working in. This prevents accidental flooding when disconnecting old fixtures or if a new connection leaks during testing. Always double-check that the water is off before proceeding with any plumbing disconnections.
How long should a beginner expect this project to take, and what's a common time-consuming step?
For a beginner, plan for a full day (6-8 hours) for this project, especially if you're unfamiliar with plumbing. Removing the old sink, particularly if it's heavily caulked or secured, can often be the most time-consuming initial step. Take your time, as rushing often leads to mistakes.
What's the most common mistake beginners make that causes leaks after installation?
The most common mistake is not properly tightening or sealing the P-trap and water supply connections. Ensure all threaded connections are hand-tightened, then given an additional quarter to half-turn with pliers or a wrench, and always use plumber's tape or pipe dope on threaded water supply connections for a watertight seal.
