Standard Shower Head Thread Size Explained

Most people usually look for the best while buying shower heads. But, knowing about the standard shower head thread size is also very important while purchasing a shower head as it has an impact on your overall showering experience.

And that’s our topic today. After reading this post, you’ll get to know the standard shower head thread size and much more.

So, without further ado, let’s get the show on the road.

What are Shower Head Threads?


Before we can talk about the best size for shower head threads, we must first establish what they are, as there might be many who are unclear about this particular term.

In very simple words, a shower head thread is an opening that connects the shower head to the pipe from which the water flows.

For most people who are not involved in plumbing work at home do not give it much importance.

The thread size is often referred to as pipe size, as well. So, the male end of the pipe is set up with the female end. 

To seal them together into place, they need a thread that can be rotated in a clockwise direction. And with that, you should be done.

But once you yourself are engaged in fixing or installing your shower head, you will understand its use and importance. It is essentially what helps to keep the head attached to the pipe properly.

Without this thread, you would have experienced leakage from the pipe.

What Is the Standard Shower Head Thread Size?

There are many people who have a unanimous choice, and for people as such, companies tend to produce generic products. In other words, we call them standard. 

To avoid confusion and additional trouble, different manufacturers have come up with a standard shower head thread size that would go very well with a standard shower head size

Now, even though there are standards, however, the standard is not the same everywhere. This means we might not get to see the same standardized size of shower head threads all over the world.

  • Standard Size in the United States of America ( USA )


In the United States, the optimal size of the thread is ½ half inch ( 12.7 millimeters ).

As it is pretty much stable, you will not have to worry about the length. It’s highly unlikely that you are going to find an aberration, as most shower heads will be made to accommodate threads that are of this length.

So, we suggest that you put all your worries to bed, and find a faucet that you find to your liking.

  • Standard Size in the United Kingdom ( UK )


Just as there is a regular size of threads assigned in the States, there is one fixed for the UK, as well.

Even though there are many things that are different between the two nations, the BPS and the NPS both require the use of the same pipe size. 

So, you will be needing and using a thread that is ½ an inch in length.

In Australia, the standard size is the same as it is in the other two countries. So there is no need to worry if you belong to that continent. The same standard applies almost everywhere.

Thread Size for Different Types of Shower Heads


Even though there is a standard shower head size that most companies follow when they produce these products, there are different types of shower heads. Some are very large, some are handheld, and then some are much smaller than the rest.

Are they going to make use of the same size of thread?

Well, for most, the answer is yes.

No matter what type of shower head you use in your bathroom, the size of the male and female pipe end will be the same. So, you will need the same size of thread.

Overall, we have so far gathered that the size of the thread does not change based on your location in either the United States or the United Kingdom.

Also, you do not have to worry whether the thread will be the right fit for a standard shower head fitting size, as long as it is ½ an inch long.

Why Is the Size of the Shower Head Important?


We have already established what shower heads are and why they are important when it comes to installing the shower heads. But, you must also know that it’s size plays a role in the whole process.

The thread is what will hold your shower head to the pipe. So, in order for the thread to do its job properly, it has to be well suited for your shower head. If they are not compatible, then you are likely to face certain issues.

One of the issues might be a loose fit, or the thread might not reach up to the shower head.

In either of the scenarios, you will have to go out and get a thread that will be a good match for the shower head you are using.

Now, if the thread doesn’t reach up to the shower head, then there is no way for you to attach it to the pipe. It means your shower head will not work. 

Another problem might be that the thread is too long. In that case, keeping them fixed together will be a hassle. That is why you need to pay close attention to the fine detail.
