If you’ve ever faced a leaky shower or decided it was time for a bathroom upgrade, you’ve likely found yourself staring at a shower handle, wondering, “How on earth do I get this thing off?” Welcome to the world of DIY plumbing, where the humble Allen wrench reigns supreme. But not just any Allen wrench—oh no. The question of the hour is: What size Allen wrench do you need for your shower handle?

The Enigma of Shower Handles
Shower handles come in all shapes and sizes, each with its secret handshake, or in this case, set screw. This small, often-hidden screw holds the key to your plumbing endeavors. Enter the Allen wrench, also known as the hex key, the unsung hero of the toolbox.
In a lively discussion, DIY enthusiasts shared their trials and triumphs in finding the right Allen wrench size for various shower handles. Here’s the scoop:
- 3/32 inchThe darling of the shower handle world, this size is commonly used for brands like Gerber. If your handle resists all attempts at removal, this might be your magic number.
- 7/64 inchSlightly more elusive, this size sometimes makes an appearance, adding a touch of mystery to the task.
- 1/8 inchA bit beefier, this size shows up when you least expect it, challenging your DIY prowess.
Keep in mind, while these sizes cover many U.S. fixtures, international brands might throw a curveball with metric sizes like 2.5mm or 3mm.
