A shower arm is the rigid pipe that connects a wall or ceiling outlet to the shower head itself. It is a distinct component from a full shower system, which typically bundles an arm and head together, and this range covers Clark-branded arms sold on their own.
When you need a shower arm on its own
There are two common reasons to buy a shower arm separately rather than as part of a full shower system. The first is replacement, an old or damaged arm can corrode, crack, or develop a leak at the wall connection over time, and replacing just the arm is more straightforward than replacing the entire shower fitting. The second is building a custom shower setup, where you want to pair a specific shower head of your choice with an arm bought separately, rather than being limited to whatever head comes bundled with a pre-packaged system.
Wall mount versus ceiling mount
Shower arms are generally designed for either wall mounting or ceiling mounting. A wall mounted arm extends out from the wall at an angle to bring the shower head to the right position over the user. A ceiling mounted arm drops straight down from above, which suits a more open overhead shower layout. These two mounting styles are not interchangeable, so confirm which type matches your existing plumbing outlet before ordering a replacement or a new arm for a custom build.
Arm length and reach
The length of the arm determines how far the shower head sits from the wall or ceiling outlet, which affects both the reach of the water flow and how it lines up with the user standing underneath. A shorter arm may leave the shower head sitting too close to the wall for a comfortable, well positioned spray, particularly for taller household members, while a longer arm extends the head further into the shower space. Measure your existing setup or consider the height of the main users in the household before choosing arm length.
Thread and connection compatibility
Because a shower arm is being bought as an individual component, thread and connection compatibility with your existing plumbing and with the shower head you intend to attach is essential. Check the connection type and thread size listed on the product against both your wall or ceiling outlet and the shower head you plan to pair it with, since a mismatch at either end will prevent a secure, leak-free installation.
Before you order
Confirm whether you need a wall mounted or ceiling mounted arm
Measure existing arm length or consider user height for reach and positioning
Check thread and connection compatibility with your wall or ceiling outlet
Confirm the arm's connection is compatible with the shower head you plan to attach
If replacing an old arm, check for matching finish if it will sit near other visible tapware
Frequently Asked Questions
What is the difference between a shower arm and a full shower system
A shower arm is just the rigid pipe connecting the wall or ceiling outlet to the shower head, while a full shower system typically bundles an arm and head together as one product. Buying an arm separately makes sense if you are replacing a damaged arm or building a custom setup with a shower head of your own choosing.
Why would I buy a shower arm instead of a full shower kit
The two main reasons are replacing an old or corroded arm without needing to replace the whole shower fitting, or building a custom shower where you want to choose your own shower head and pair it with a separate arm, rather than accepting whatever head comes bundled with a pre-packaged kit.
How do I know if I need a wall mounted or ceiling mounted arm
This depends on your existing plumbing outlet. A wall mounted arm extends from the wall at an angle, while a ceiling mounted arm drops straight down from above for a more open overhead layout. Check which type your current outlet is set up for before ordering, as the two mounting styles are not interchangeable.
Does the length of the shower arm matter
Yes, arm length affects how far the shower head sits from the wall or ceiling and how well the spray lines up with the person showering. A shorter arm can leave the head sitting too close to the wall, particularly for taller users, so it is worth measuring your existing setup or considering household height before choosing a length.
Will any shower head fit any Clark shower arm
Not automatically. You need to check the thread size and connection type on the arm against the shower head you intend to attach, as well as against your existing wall or ceiling outlet. A mismatch at either end can prevent a secure, leak-free fit, so confirming compatibility before ordering is important.
