A plumbing rough in is the process of running the pipes for a new bathroom vanity before the actual installation. This is done so that all the plumbing is in place and ready to go before the vanity is installed. Doing a plumbing rough in for a bathroom vanity is a fairly simple process, but it is important to make sure that all the piping is properly installed and that there are no leaks.
A plumbing rough in for a bathroom vanity generally includes installing the water lines and drains for the sink and other bathroom fixtures.

What is the plumbing rough-in height for a bathroom vanity?
The standard rough-in height for residential bathroom sinks is 31 inches from the floor to the rim of the sink. Bathroom sinks in compliance with ADA requirements measure 34 inches from the floor to the rim. This is to accommodate people with disabilities who need a higher sink to use.
The water lines are roughed in approximately 21 inches above the finished floor. This is to ensure that the lines are not damaged during the construction process.
What height should a sink drain be rough-in
The correct rough-in height for sink drains to pass the inspection is between 18 and 20 inches. Standard sink drains usually start from 24 inches and stop at 28 inches, so the rough-in height should be slightly lower than this height range. This will ensure that the drain meets the requirements for the inspection.
The 1 1/2 inch size pipe is used to capture water that might flow out of a kitchen sink, a bathroom vanity or a tub. The two inch pipe is commonly used to drain a shower stall or washing machine, and it might be used as a vertical stack for a kitchen sink. A three inch pipe is what’s used in homes to pipe toilets.
How far should Vanity drains be from stubs?
A drain stub-out is a pipe that extends from a fitting to a point beyond the wall. The standard length is 4-6 inches, but it can be longer or shorter depending on the needs of the space. The cut end of the pipe should be 3-4 inches away from the wall.
The National Kitchen and Bath Association (NKBA) has a plumbing standard that requires a 2″ drain pipe for bathroom sinks. This is to ensure that the sink can handle the proper amount of water flow and drainage.
How high should drain be for floating vanity?
If you are planning on doing your own plumbing, make sure to rough-in the plumbing at 17″-20″ from the ground. This will give you enough clearance to install the p-trap without too much difficulty. Keep in mind that you will need to mount the vanity top at 34″ from the ground, so plan accordingly.
When measuring plumbing for a vanity, you will want to measure the distance between the edge of the vanity outline and where the plumbing comes out of the wall. Note both the height and width of the pipes. You will also want to measure how large a hole will need to be cut to accommodate the pipes.
Can a washer and toilet share the same drain
If your washing machine is connected to your toilet drain, it’s not uncommon for your toilet to gurgle when your washer machine drains. This is because the washing machine is in between your toilet and sewer stack.
It is important to make sure that the slope of your drain line is correct in order to ensure that the water will flow properly. The ideal slope for any drain line is ¼ inch per foot of pipe. This means that for every foot the pipe travels horizontally, it should be dropping ¼ inch vertically. Many drains either have too little slope or too much slope, which can cause problems. Make sure to check the slope of your drain line and adjust it if necessary.
Can a sink and shower share the same drain?
All bathroom fixtures including sinks, baths, and showers can share a common drain pipe. This is commonly seen in older homes where all the fixtures are grouped together in one room.
If you are installing pipe yourself, or hiring a professional to do it, it is important to make sure that the pipe is sloped properly so that water will drain properly and not back up in the drain line. A good rule of thumb to follow is a drop of ¼-inch per foot.
Can a sink drain have a 90 degree elbow
A larger-radius (sweep) 90-degree bend is sometimes used at the base of a vertical drainage stack where the wastewater starts to travel horizontally. This allows the water to flow more smoothly through the pipe and can help to prevent clogs. A sweep 90-degree fitting is also often used where a drain pipe pops out of a wall for a kitchen, vanity or laundry sink. This can help to reduce noise from the drain and can make the area around the sink easier to clean.
In order to install a bathroom sink, the water lines must be roughed-in 3 inches above the drain. The finished floor should be measured 21 inches above the drain, and the hot and cold lines should be spaced 8 inches apart from each other. To properly install the sink, 4 inches should be measured from the center of the drain to the left and right.
What size pipe is used for bathroom plumbing?
It is generally advisable to use 3/4-inch pipe for bathroom supply lines in order to maximize water pressure. 1/2-inch pipe may be used for short runs only.
When it comes to toilet vent pipe size, it’s typically recommended that you go with a 2″ PVC pipe. This is according to the uniform plumbing code (UPC).

A plumbing rough in for a bathroom vanity typically includes the installation of water lines, drainage lines and vents.
The rough in for a bathroom vanity is the portion of the plumbing that is installed before the finish work is completed. This includes the pipes and fittings that are necessary to connect the vanity to the water supply and drainage system. The rough in should be completed before the vanity is installed, so that the plumbing connections are hidden behind the vanity.
