What does a vanity installation include?
A vanity installation is the setting of a new cabinet, top, sink and faucet, then connecting them to your water and drain. The plumber installs the faucet and drain assembly, and fits new shutoff valves and supply lines. They connect the P-trap to the wall drain and test for leaks. A carpenter or the installer usually levels and secures the cabinet.

How can a new faucet save water?
A water-efficient faucet is one that uses less water without feeling weak. WaterSense-labeled bathroom faucets use 1.5 gallons per minute or less. Many use aerators that mix air into the stream. The EPA WaterSense bathroom faucet page lists labeled models. A cheap aerator swap can also cut the flow of a faucet you already own.
What should I check before buying?
Check these three things before you order a vanity:
- Drain height. A new cabinet with drawers may need the drain moved.
- Faucet holes. Single-hole, 4-inch centerset and 8-inch widespread faucets don’t swap freely.
- Shutoff valves. Old multi-turn valves should be replaced while the cabinet is empty.

Common questions
Can two sinks share one drain?
Often, yes. Two sinks close together can share one trap and drain with the right fitting, as long as the drain is sized and vented for both. Sinks more than a few feet apart usually need separate drains. Your plumber will check the existing drain size and the vent before you order a double vanity.
Are vessel sinks harder to plumb?
A little. A vessel sink sits on top of the counter, so the faucet must be tall or wall-mounted to clear the rim of the bowl. The drain also uses a different fitting, and many vessel sinks have no overflow. Pick the faucet and sink together, and check the combined height works for everyone who uses the bathroom.
What flow rate should a bathroom faucet have?
A WaterSense-labeled bathroom faucet uses 1.5 gallons per minute or less. According to the EPA, that cuts a sink’s flow by 30 percent or more from the standard 2.2 gallons per minute without hurting performance. That’s plenty for washing hands and brushing teeth. Most labeled faucets use an aerator that mixes air into the stream.
