Where the P-trap goes under the sink determines the drain’s rough-in height. In other words, the higher the counter height, the higher the rough-in height for the drain. If you are installing a bathroom sink drain, the rough-in height naturally goes lower than that in a kitchen due to the counter height. The standard counter in a kitchen is 36 inches, but a standard bathroom vanity may only rise as high as 30 inches.Ĭonsequently, the rough-in drain drops as low as the counter height goes. For example, a kitchen counter is typically higher than that in a bathroom or any other room.
It is important to note that different rooms have varying counter heights. Keep these in mind since the pipes typically hang about 20 inches off the floor. In most cases, the water pipes will go above the rough-in, which means they will be a few inches higher than the drain rough-in. Many sinks have pipe connections in the center under the sink, but some prefer moving the pipes to one side to make storage room for items around the house.īut the drain must not get in the way of other pipes, so you may want to measure its rough-in height with the pipes in mind. The type of sink drain pipe connections you make may affect the rough-in height. We will get to the counter height factor later. Higher counter heights can even out the rough-in height if the depth of the sink bowl is more than usual. That is if you choose to use the standard height for all counters. The deeper the sink, the lower the p-trap drops to the floor, which may reduce the rough-in height to sixteen inches from the floor.
While a deeper sink gives you more room to handle more dirty dishes and clean better than a standard depth one, it will tamper with the drain’s rough-in height. Sink depth can be deeper than the standard measurement, and you may find some as deep as ten to twelve inches, especially if it is a kitchen sink drain. Typically, the depth of your sink is eight inches, but this is not a general rule. When measuring the rough-in height for a sink drain, you must consider the size of your sink and the type for installation. Without them in mind, you can make a grave mistake and fail the inspection process. Factors to Consider When Checking the Rough-in Height of a Sink Drainīefore getting the correct measurement for a sink’s plumbing rough-ins, you must consider some critical factors. Again, note it on the paper and check the width of the sink and the countertop space where the sink will fit.

Note the measurement on a piece of paper and check the full length from the top of the sink. So, to get the correct rough-in height, check the depth of the sink. Additionally, this affects the rough-in height. That will inform the type of sink you choose, affecting its depth. But before you can do that, you must choose the countertop height. While it is necessary to measure the rough-in sink drain height, it is equally as crucial to get the correct sink installation height. Measuring the Sink Drain’s Rough-in Height You can always change the drain’s depth and height when fully installing it. There is also adequate room for the cold water lines and hot water pipes to prevent crowding under the sink. You must allow room under the sink drain to accommodate the p-trap so it is not too close to the floor and encourages proper drainage. 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. The correct rough-in height for sink drains to pass the inspection is between 18 and 20 inches. This inspection failure can lead to the loss of the building or drive a need to start the construction all over again.
So, if your sink drain installation does not meet the correct rough-in height, it may fail the prerequisite inspection. At this inspection stage, the building is in the rough-in stage, and none of the pipes or plumbing fixtures are connected yet. When a building is undergoing renovation or fresh construction, there is an inspection to check how much it adheres to the building regulations.
The Correct Rough-in Height for Sink Drains You can determine what works for your house’s dimensions and whether or not your building passes an inspection. Let’s look at the correct rough-in height for a sink drain and the factors that affect it. However, what is the rough-in height for sink drains?
