The hardest part of plumbing is typically the rough-in. Sometimes it seems unnecessary to complete the last step of connecting the tub, toilet, or sink. However, it need not be that intimidating. Sinks, bathrooms, and tubs/showers have standard rough-in plumbing sizes.
Additionally, fixture makers often include rough-in requirements in their product documentation. Always compare the common measurements to the manufacturer’s specifications to ensure that the common measurements will work for your installation.
Bathroom sink plumbing rough in height
Sinks in bathrooms are crucial since they use for various functions. The individuals that live there have an impact on the bathroom sink’s height. The height usually is 24 inches off the ground, aside from that. Rough plumbing maintains a height of 18 to 20 inches.
This page will give you more information on bathroom sink plumbing rough-in measurements and what that height usually is. Before replacing the sink in your bathroom vanity, be sure the water and drain lines are properly marked.
Only 4 inches separate the water supply pipe from the sink drain. The sink’s drain line is located in the center of the vanity cabinet, about three to four inches below the water supply line. All drains and pipes vary depending on the vanity’s height, with more oversized vanities necessitating higher lines.
What is plumbing rough?
Different mechanical, electrical, and plumbing lines are installed during a building project’s rough-in phase. Ductwork, plumbing, and electrical are built during this stage of development to address any accessibility concerns or space limitations.
Bathroom sink plumbing
There are two ways to install a sink. The rough-in stage follows completion, which involves attaching the sink and faucet to the stubs. If you can complete this phase correctly, you may install the sink in your bathroom without hassles. The rough-in system is the most common form.
You may use the one to two-inch supply pipes from the tub or shower, as sinks don’t require a lot of water. It is usually needed to vent the sink to guarantee proper drainage. The vent lines must come from the drain, be five feet from the trap, and Knott to prevent roof infiltration. They must also be situated five feet away from the drain.

Rough-In dimension terminology
Centerline is a common phrase used to describe plumbing measurements. Similar to the building word “on-center,” “centerline” refers to a hypothetical vertical line that traces through a critical reference point (usually the drain pipe). If two pipes are to be spaced 10 inches apart, for instance, you measure 10 inches between the centers of the lines rather than 10 inches between their borders.
The base floor height is another often-used phrase. In newly constructed homes, this refers to the subfloor or the finish flooring (in remodeling). Remember that not all dimensions are absolute; consider these dimensions broad principles. They will change based on your bathroom.
How to build a sink?
Installation of the pipes
The locations of the supply and drain stub outs are pretty important. The middle of the drain should be between the stubs, and it must align with the bathroom sink. You must switch off the water supply and open the walls to place the pipes through them before you can push the tees into the lines where the store will come from.
The drain must slope at least 14 inches in the direction of the sewage line. The vent must continue to decline similarly in the order of the tie. Before completing the installation, you must allow the stub-outs to extend further from the cap and wall.
Prepare the stub-outs
The shut-off valves must be fitted on the stub-outs before hanging the sink on the wall. The valves must be inserted into the pipes or tightened with a wrench before using the pipe cutter to separate the caps. You must additionally input the valve option if you’re utilizing CPVC pipe rather than copper material. An adapter will accomplish the intended task if you choose not to attach the P-Trap.
Connecting the sink in the bathroom
Since the drain and faucet are already in place, you won’t need to worry about anything. If the rough-in is done well, you are 90% done with the project. The supply hose links the faucet inlets and shutdown valves for the faucets. Using pliers, you must tighten the fittings. The most excellent fit for it to fit with the sink would be if you could get it. Thus you must verify the hose’s specifications when you buy it. You may use the sink after attaching it to the pop-up stopper.
How High Should Bathroom Sink Drains Rough In?
To comprehend the rough-in heights for bathroom sinks, you must be aware that sink drain lines should be between 18 and 20 inches long. The water supply pipes, which need to be a few inches higher and 20 to 22 inches above the bathroom or kitchen floor, are frequently placed on the drain line sides. At this height, most bathroom sinks should fit.
