This work is typically done by a plumber, and it is important to have it done correctly to ensure that the vanity functions properly and without leaks.

Planning the Plumbing Rough-In

Before starting the plumbing rough-in, it is important to carefully plan the layout of the vanity and the location of the plumbing fixtures. This will help to ensure that the plumbing is installed in a way that is both functional and aesthetically pleasing.

The location of the drain lines
The location of the vent pipes
The size and shape of the vanity
The location of the other fixtures in the bathroom

Installing the Water Supply Lines

The water supply lines for a bathroom vanity are typically installed in the wall behind the vanity. The lines should be made of a durable material, such as copper or PEX, and they should be sized to meet the flow requirements of the fixtures.

To install the water supply lines, the plumber will first need to shut off the water supply to the bathroom. Once the water is shut off, the plumber will cut holes in the wall for the water supply lines. The lines will then be inserted into the holes and secured with clamps.

Installing the Drain Lines

To install the drain lines, the plumber will first need to cut holes in the floor for the drainpipes. The lines will then be inserted into the holes and secured with clamps.

Installing the Vent Pipes

The vent pipes for a bathroom vanity are used to prevent sewer gases from entering the bathroom. The vent pipes should be made of a durable material, such as PVC, and they should be sized to meet the venting requirements of the fixtures.

To install the vent pipes, the plumber will first need to cut holes in the wall for the vent pipes. The lines will then be inserted into the holes and secured with clamps.

Testing the Plumbing Rough-In

Once the plumbing rough-in is complete, it is important to test the system to ensure that it is working properly. The plumber will typically do this by turning on the water supply and checking for leaks. The plumber will also check the drain lines to ensure that they are draining properly.
