One of the main issues most people suffer nowadays is finding out the right kitchen sink drain height.
Homeowners installing new sinks usually find that they don’t know the ideal drain height. And this happens because all sinks are different, so they all demand different measurements.
There’s really no standard height for the drain of a sink. But you should still make the right calculations and make the drain at the right distance.
Eager to find out the ideal drain height for your sink? Then keep on reading, and you’ll find out!
Average Height of a Drain
The height of a sink from the floor is usually between 30 and 45 inches. This distance between the sink and the floor takes the size of the sink into account, as well as the depth and overall design. Now, if the height of the drain can reach between 30 and 45 inches, how much should the drain be?
If we’re talking about a kitchen sink standing at 35 inches, then you’ll need the drain to be at 28 inches or so. But if the sink stands at up to 45 inches, then 35 inches will be enough for the drainpipe.
But it is also a matter of the type of plumbing and drains you want to install. Some designs may demand a little more height to work correctly, while others work at any height without problems.
ADA-Compliant Sink Drain Height
If you want to install a sink in a commercial or public place, then you’ll need to follow ADA rules. These rules state that the distance between the sink and the floor should be 34 inches. This makes sinks tall enough for most people to use without problems.
However, how should the drain be with ADA regulations? Well, it depends. But overall, you could say that 27-inches is a safe height for the drain. This varies exponentially if we’re talking about children-specific sinks. In this case, the sink should be at about 24 inches, so the drain should be no more than 17 inches high.
Vessel Sinks Drain Height
While vessels sink tends to look better than standard sinks, they also follow different measurements in terms of height. For example, vessel sinks tend to be way higher than normal ones because they go over a countertop. This top, for sure, also has a specific height – so you may be looking at a very high sink overall.
The typical height of a countertop or dresser tends to be between 27 and 32 inches. Some models can be higher or smaller accordingly. But if we take that height into consideration, you could say that a vessel sink may stand as high as 40 to 50 inches. This will leave a lot of space below for the drain to be installed.
So, to have better measurements, you will have to know the exact height of the vessel sink — usually, about 27 inches for anything over 35 inches in height. And for sinks standing below 35 inches, then you can go as little as 20 to 25 inches accordingly.
Not only you will have to consider the type of sink you’re using, but also what kind of plumbing you want to install. Remember that the whole installation will come with tubes and pipes, so you have to make sure that the desired height of the drain also fits with the type of plumbing you’re using.
For that, you will have to consider the overall space available below the dresser, countertop, or the sink itself. You can install regular plumbing following standard or ADA-compliant drain heights for places with free space below. The drain should be at about 75% of the sink height.
But for places with not much space below, you’ll have to find the perfect height. For that, make sure you measure the distance of the sink from the floor and find the ideal pipes that fit below.
In this case, we recommend the thinnest drain pipes possible. But make sure they’re still broad enough to let water and residues pass through without problems.
Usually, the height should vary according to the type of sink and counter, but it should be no more than 50% of the total distance between the sink and the floor.
When to Measure
The common problem for most self-installers is finding the right moment to measure everything. Whether it should be before the sink is installed, after, or whenever it feels like the right time – it can be hard to figure out when.
But in reality, you should measure and plan the whole sink & drain installation before you start doing anything. Remember to consider the type of sink you’re installing, the place you’re installing it, the amount of space available for the drain plumbing, and the final height of the whole sink.
Once you consider all that and measure accordingly, then you can install your sink with the perfect drain height.
