There are a few things to keep in mind when doing a bathroom sink drain rough in. The first is to make sure the sink is level. The second is to mark the center of the sink on the wall. The third is to find the studs in the wall so you know where to drill the holes.
The typical bathroom sink drain rough in is about 2 inches from the edge of the sink to the center of the drain.

What is the rough-in height for a bathroom sink drain?
The rough-in dimensions for bathroom sinks vary depending on the type of sink. For supply lines, vertical sinks will have two holes, each 2-3 inches above the drain line. Horizontal supply lines will be 4 inches to left and right of the centerline. The discharge/drain hole for vertical sinks will be 16-20 inches from the floor.
The most important thing to remember when choosing a drain for your bathroom sink is to make sure that it is the same size or smaller than the hole in your sink. This will ensure that your sink functions properly and that water will not be able to escape.
Can you put a 90 elbow in a sink drain
It’s a bad plumbing practice to have a hard 90-degree bend in a horizontal drain line that’s buried in a slab or otherwise hidden. If you have to make a 90-degree bend, use two 45-degree fittings and put a small piece of straight pipe between the fittings, if possible. This will help to prevent clogs and other issues that can occur when there is a hard 90-degree bend in the drain line.
A wall drain is a drain that extends from a fitting to a point beyond the wall. The drain usually has a minimum slope of 1/4 inch per foot from the stub-out to the point where it ties into a main waste pipe.
How much drop should you have for every foot of drain pipe?
The ideal slope of a drain line is ¼ inch per foot of pipe. In other words, 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. That’s right, it is possible to have too much slope in your drain lines.
The 1½-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 may be used as a vertical stack for a kitchen sink. A three-inch pipe is what’s used in homes to pipe toilets.
Can you use 1 1 2 pipe for bathroom sink drain?
Some older sinks may have even smaller pipes like 1 1/4-inch in diameter but these are not as common. If you have a standard kitchen sink drain, then a 1 1/2-inch pipe is typically sufficient. However, for a double kitchen sink or a bathroom drain, you may need 2-inch drainage pipes.
The standard drain hole diameter for both single and double basin sinks is 3-½”. If you are not connecting to a garbage disposal, you will need a drain with a strainer flange and basket.
Why are there 2 holes in a sink drain pipe
Overflow holes are an important safety feature on sinks. They help to prevent accidental overflowing by providing an escape route for air in the drain. Depending on the design of your sink, it may have one, two or three holes. They may appear between the faucet valves, facing toward you, or under the near rim, facing the mirror.
French drains are installed with a slight slope (usually 1% or less) to allow water to flow through the pipe and away from the home or other structure. If a French drain is not installed with a slope, water will collect in the pipe and eventually lead to clogs or other issues.
Will drain rods go around bends?
If you’re having trouble getting your drain unclogged, make sure you’re using a highly flexible drain rod. These rods are designed to bend and adapt to the contours of the pipes, so they can get around any bends. If you’re ever in doubt, consult with a drain professional.
If you’re looking to install or replace a sink drain, it’s important to choose the right material. Plumber’s putty is not always the best option, as it can deteriorate over time and cause leaks. In situations where a gasket is not supplied by the manufacturer, silicone caulk is a better choice. Always be sure to read the directions for your particular drain assembly to ensure proper installation.
What is a good rule of thumb for installing drainage
This is a great rule of thumb to follow when installing or repairing pipe. This will ensure that water will drain properly and won’t back up in the drain line.
The pitch is limited to a maximum of 1/2-inch per foot. The only exception to this requirement is the vertical drop from the fixture. For example, a lavatory can have a vertical drop from the trap arm to the drain below the floor.
Does sink drain have to be centered?
A centered drain in a kitchen sink can be problematic as it can more easily become blocked by dishes and food debris. This can then cause water to build up and potentially overflow. A centered drain is also not ideal in small kitchens as it can waste valuable storage space.
Backups can occur when the slope of a pipe is too steep or not steep enough, preventing liquids and solids from draining. If a pipe becomes clogged due to an improperly sloped pipe, water may be forced around the pipe, causing extreme erosion to the surrounding soil and bedding.
Final Words
There is no definitive answer to this question since it will depend on the specific bathroom sink drain you are using and the rough in for that particular sink. However, in general, you will want to make sure that the rough in for your bathroom sink drain is properly installed and aligned before attaching the sink drain to it. If everything is installed correctly, the rough in for the bathroom sink drain should be level and flush with the surrounding wall or countertop.
There are a few things to keep in mind when installing a bathroom sink drain. The first is the rough in. This is the distance from the back of the sink to the center of the drain. The second is the distance from the center of the drain to the outside edge of the sink. The last is the height of the drain. The rough in for a bathroom sink is usually about 12 inches.
