Showerheads can help you get ready for work in the morning or unwind after a long day by creating a stimulating or calming experience. However, if you’re in the market for a new showerhead, you might be wondering if any would fit your shower arm.
The good news is that there is a quick answer for most households:
In Canada and the United States, showerheads are threaded with a 1/2-inch NPT universal thread size. As a result, any showerhead purchased locally in these countries should work with your shower arm.
Showerheads from different nations, unusual showerhead designs and those from very old homes are the only exceptions to this rule.
There’s a lot more to choosing the right showerhead. Check out the details and tips provided in this article to assist you in choosing a compatible showerhead properly so you don’t end up spending hours scouring the Internet or going back and forth from the hardware store.
Are Shower Heads Universal: Here is an Explanation
As previously stated, the usual size for showerheads in Canada and the United States is 1/2-inch NPT, but there are several exceptions to this rule that should be considered when purchasing a new shower head for your home or replacing an old one.
Showerhead Sizes in Other Countries
If you’re shopping online and come upon a fantastic showerhead produced in another country, make sure to read the specifications carefully. The standard thread size in Canada and the United States is 1/2-inch NPT. The abbreviation stands for National Pipe Thread Tapered.
Most countries, on the other hand, employ a different pipe thread standard called BSP. The abbreviation stands for British Standard Pipe. This thread standard is most commonly found in South Africa, Asia, Europe, Australia, and New Zealand. In these areas, a standard shower head thread size is 1/2-inch BSP.
In most cases, you’ll find showerheads with the standard half-inch NPT in the market. You might, however, come across some unconventional showerheads. Unless you plan on doing some structural changes to your plumbing, then you’ll want to avoid this type of equipment.
Very Old Houses
While installing pipes to accommodate a 1/2-inch NPT showerhead is now common practice, this was not always the case. If you reside in an older house, your new showerhead might not be compatible with the current shower arm.
If you have this problem, you should consider replacing the shower arm. However, if you don’t want to meddle with the shower walls, you can also find an adapter.
Tips on How to Get the Perfect Shower Head Fit
You’ll need a decent technique to double-check that your showerhead will fit your shower arm as you go through all of your showerhead alternatives. That’s what we’re going to be discussing here.
Tip 1: Take Your Old Shower Head to the Store with You
You, like many others out there, might be staring at your shower arm and unsure whether it is the standard size. In that scenario, just removing and taking your old showerhead to the retailer will save you a huge amount of time.
You can also detach the shower arm and bring it if you don’t have the existing showerhead. That way, you may get assistance or test compatibility before making the trip home to try it out.
Tip 2: Measure Your Shower Arm
If you can’t take with you the existing parts to the store for some reason, or if you buy everything online, you can double-check the threads of your shower arm by measuring it. Below are some key steps to follow when measuring your shower arm.
Male or Female Threads
To begin, determine if the threads on your shower arm are male or female. Is the fitting threading on the exterior or inside? Male threads are usually on the outside, while female threads are on the inside.
Because female and male threads join, if your shower arm has female threads, you’ll need a showerhead with a male threaded connector and vice versa.
Parallel or Tapered
The next step is to determine if your threads are parallel or tapered. The threads maintain a constant diameter if they are parallel. The diameter will drop along the threads if it is tapered. By simply glancing at it, you should be able to tell.
If you’re in Canada or the United States, the probability is that it’s tapered, but double-check to make sure your connecting parts are compatible, as a tapered male component will only link with a tapered female part.
Outer and Inner Diameter
The last step is determining the diameter. If your shower arm has male threads, then you should measure the outer diameter. But if your shower arm has female threads, then you should measure the inner diameter. The letters “O.D.” stand for outer diameter, and “I.D.” stand for inner diameter.
The trade size or nominal size will be determined by comparing the actual measurement to a thread chart. This nominal size is a naming practice used to make it easier to identify parts.
These are the most important measurements to keep in mind while looking for showerheads. We understand if it looks excessive. At the store, don’t be hesitant to ask for assistance and clarification.
Tip 3: Ask a Friend
Consider seeking guidance from a plumber or someone who knows a lot about plumbing if you are one of the fortunate people who has a family member or friend who is a plumber or knows a lot about plumbing. It could help you save a lot of time and effort.
Tip 4: Purchase a Variety of Sand Return the Ones That Aren’t Working
It is recommended that you try the tips above before resorting to this one to guarantee that you have a suitable-sized showerhead.
You can always buy various showerheads with different connectors and sizes if you don’t have the instruments to measure, an expert to consult, or can’t get your current parts to the store.
To see what fits, try connecting them all to your shower arm. Be cautious about making sure it fits well without forcing it, as certain sizes may be similar but have different threads.
