How to Install a Vessel Sink
Part of our Sinks, Faucets & Storage guides.
Vessel sinks are among the easiest sinks to install because they sit on top of the counter. Turn off the water (and power at the breaker for anything electrical) before starting, and follow the product manual where it differs from these general steps.
| Time | 2-3 hours |

| Difficulty | Moderate |
| Tools | Hole saw, drill, silicone, wrench, plumber's putty |
Step by step
- Plan placement. Center the sink, leave room behind for the faucet and check the spout reaches the bowl center.
- Cut holes. Drill the drain hole and faucet hole with a hole saw.
- Install drain. Fit the drain with mounting ring/gaskets per the manual.
- Set the sink. Bed it with silicone on the ring and align the drain.
- Install faucet. Mount a tall vessel faucet; connect supply lines.
- Connect trap. Attach the P-trap and check alignment.
- Test. Fill and drain; check for leaks.
Tips & common mistakes
- Vessel sinks without an overflow need a non-overflow drain.
- Lower vanity heights make vessels more comfortable.
Choosing the faucet
Measure from the counter to just above the vessel rim: the faucet spout should clear the rim by 1-2 inches. Then measure from the faucet hole to the drain center: the spout reach should end roughly over the drain. Too short and water hits the bowl's back wall; too long and it splashes out.
Drain choice
Many vessel sinks have no overflow hole, so you need a drain without overflow slots, or water will leak out of the drain body. Grid drains and push-pop drains are common. If your sink has an overflow, use a drain with slots that line up with it.
Cutting the counter
Mark the drain and faucet centers with painter's tape on the counter. For stone, use a diamond hole saw with water to keep it cool; for wood or laminate, a standard hole saw works. Drill slowly to avoid chipping.
Final checks
- Fill the bowl to the top and release it to test the drain and trap under full flow.
- Run the faucet on full hot and full cold and check supply line connections.
- Run a thin bead of clear silicone around the base if the manual recommends it, to stop water getting under the bowl.
