Moving plumbing to fit the vanity entails cutting the existing pipes and redirecting them to the vanity’s centre. Reconfiguring sink drains is challenging because they demand p-traps to block sewer gases from leaking through the drain.
Upgrading your bathroom enhances efficiency and liability in your washroom, making it more pleasant and accessible with every fixture fixed appropriately. If your current bathroom cannot exhibit these qualities, it’s high time you think about moving plumbing to fit vanity.
Pipe fitters typically position water supply lines for vanities on the back wall underneath the sink or the sides of the cabinet walls beneath the sink. However, they run through the floor right under the sink in the middle of the vanity. Any of these spots will suffice.

How To Move Plumbing To Fit Vanity
Rerouting pipes to suit your bathroom vanity does not have to be arduous. Check out the simple steps below:
1) Preparing The Plumbing
You’ll need a marker, an adjustable wrench, a hacksaw, a drill, supply pipe, a 3/4-inch hole saw attachment and 90-degree push-to-fit elbow fittings.
Start by turning off the primary water valve (you will find it in the crawl or basement area) in your house. It will cut off the water supply to all the piping on the premises as you work.
Open all the house’s taps to discharge as much water as possible from the plumbing.
Wrap an adjustable wrench around the control valves on cold and hot-water pipes. To disconnect the supply lines, rotate the valves anticlockwise.
Measure from the edge of the sink to the middle.
Mark the two areas two inches apart on the under surface of the vanity. For instance, if the sink’s midpoint measures 13 inches from the side, estimate 13 inches from the bottom of the vanity to the sink’s center and draw two markings 2 inches apart.
Here, the dual supply lines will emerge through the vanity’s floor.
Using a 3/4-inch drill bit, make holes through the marks made in the previous step since that is where you will find cold and hot-water pipes.

2) Installation Of New Supply Lines
Access the pipework on the bottom of the sink vanity. Access it from the basement or crawl area or take off the baseboard beneath the sink cabinet.
Use a pipe-cutting tool or a hacksaw to cut the cold and hot water lines to provide at least 3 inches of gap between the bottom of the vanity sink and the pipes.
Install 90-degree compression elbows on the cold and hot water connections, with the fittings’ ends pointing toward the middle of the sink.
Cut two sets of supply pipes to sizes that go from the elbows to the slots for the incoming supply line connections. Insert the pipe portions into the elbow fittings.
Attach two more 90-degree elbow fittings to the supply pipes’ ends.
Cut two 5 inch pieces of pipe. Insert the pieces into the holes in the vanity’s center and into the elbow adapters.
Place the previous supply valves on either tip of the supply pipes and secure them using a wrench.

How To Conceal Waste Pipes Under Vanity
You have moved plumbing to fit the vanity, but the waste pipe seems out of place. Here are some ideas for hiding a waste pipe beneath a vanity:
1) Use Bottle Traps
Plumbers frequently install bottle traps on open vanities or wall basins where you can see the sewage pipe while entering the restroom. Bottle traps will cost you money, but they are inconspicuous and attractive.
2) Hide It In The Vanity Cabinet
If your bathroom features a wall-hung vanity, the drainpipe should preferably come through the wall and into the vanity’s rear with a p-trap. An s-strap can also come in handy if your vanity has depth.
The amount of waste entering the rear of the vanity would depend on how high it is.
3) Integrating Chrome-plated Traps
It’s a little complicated, but it looks elegant on open vanities with uncovered waste and traps. A plumber installs and welds a chrome trap to the sink before detaching it to have it chrome plated.
Contingent on how active the chrome plater is, it might take a day or more. You can pick up the traps and take them to the site after chrome-plating them.
If you opt for PVC, you can incorporate a chrome plate. However, ensure you use a clean PVC for effectiveness.
4) Paint The Waste Pipe Out
You can use this approach if you are on a tight budget. Simply paint the drainpipe with the same color as your vanity.
5) Box It Out
If a sewer pipe still seems messy after painting, contact your plumber to box it out.
