Installing a Kitchen Sink Drain

The best practice when it comes to installing a kitchen sink drain to achieve its ideal height from the floor is to first be sure your measurements are correct. As the saying goes, “measure twice, cut once.” This means you should double-check your measurements before cutting the materials so that you get things right the first time.

This applies to measuring what is needed for your kitchen sink drain to achieve the ideal height. You must consider what measurements are needed to ensure that you are able to complete a project the first time you attempt it. This saves both time and money.

The necessary measurements to help you determine the rough-in height for your kitchen sink drain depend on a few variables. You have to factor in the height of the countertop, as well as the depth and width of the sink that you choose.

Bathroom faucets come with a drain while kitchen faucets do not. Pay attention to this when choosing a kitchen sink. Make sure the sink comes with a drain or you will have to purchase one that is the right size for the sink you have. It depends on the brand whether or not your sink comes with a drain.

What is the rough-in height for kitchen sink drains?

*

The average rough-in height for kitchen sink drains varies between 20 to 24 inches from the floor. The preferred height is dependent on the counter and trap. You are able to adjust the height of the sink drain and depth while going through the installation process.

A few aspects to consider when determining the rough-in height for your kitchen sink drain are the location of the p-trap, pipe connections, type of sink, and the height of the countertop.

When you take measurements make sure that you account for enough room for the p-trap to be located 24 inches or less below the sink drain. If your sink drain is closer to the ground, your p-trap will be closer to the drain than 24 inches. It all depends on the depth of your sink and the height of your vanity.

For example, if your sink vanity measures 40 inches in height at the countertop, with an 8-inch depth of the sink, the drain would then have 32 inches between the floor and where it is. You can choose the height of your countertop first and then the depth of your sink before figuring out where the drain will sit.

Does a sink drain have to be centered?

A sink drain does not necessarily have to be centered. On the other hand, the sink drain does have to be installed in such a way that the water will be able to get to it so that the sink still drains.

An example of kitchen sinks with an off-center drain is those made by Haven’s Luxury Metals. Having the drain off-center provides the same functionality as a double-bowl sink.

A drain that is off-center allows you to set dishes in the middle of the sink without blocking the drain and makes it so that you are able to prepare food on one side of the sink and dry dishes on the other side simultaneously.

Are the pipes under my kitchen sink centered?

Not always. In fact, there are different traps such as a J-shaped, C-shaped, and U-shaped traps. You will need to move the p-trap depending on what shape it is and if you can easily do so. The most commonly used p-trap is a U-shaped trap.

Whenever the pipes under your sink are off to one side, you have more space available for storage. This also allows you to install wider drawers if you want to.

Can I install a deeper kitchen sink?

*

Yes, you can install a deeper kitchen sink as long as the counter you choose is high enough to allow for the pipes that have to be installed below. A lot of people like to have a deeper sink so that they have more room for dirty dishes. Having a deeper sink also gives you enough space to wash your hands without feeling like your hands are laying in the bottom of the sink.

It is important to be mindful of the fact that you will have less space between the sink drain and the floor if you install a deeper sink. This is okay as long as you install piping meant for a smaller space. If you install a deeper sink, the sink drain will be closer to the ground than it would have been otherwise.

How do you measure a kitchen sink drain?

In order to measure a kitchen sink drain properly, you must first measure the height between the floor and the top of your counter. Next, you must consider the depth of the sink that you want to install.

As long as the p-trap is installed no more than 24 inches below the sink drain, you should be fine. Measure the height of your countertop then subtract the depth of your sink to determine how much space you will have between your sink drain and the floor.

In Closing

The rough-in height for the kitchen sink drain is between 20 and 24 inches. This varies depending on the height of the vanity or counter and the depth of your sink. The taller the vanity or more shallow the sink, the further from the ground your sink drain will be placed.

Not all kitchen sinks come with a drain. Depending on the brand of kitchen sink that you buy, you might need to purchase a drain separately.

A sink drain does not necessarily need to be centered. If the drain is off-center it must be installed in such a way that it is the lowest point of the sink. An off-center drain makes it so that you can use the sink for multiple reasons at the same time.

The pipes under your sink are not always centered. If they are off to one side, you will have more space for the drawers and storage underneath.

Installing a deeper kitchen sink simply means the sink drain will be closer to the ground. You must be sure to get the correct piping to properly fit in the space remaining between the sink drain and the floor.
