How to Install a Shower Arm Diverter: Step-by-Step Guide (2026)

Installing a shower arm diverter might seem daunting, but it's actually a straightforward DIY project you can tackle in under an hour! This step-by-step guide will walk you through the process, even if you're a complete beginner. By the end of this article, you'll have a fully functional shower arm diverter ready to give you the shower experience of your dreams! Follow along and upgrade your shower with confidence.

Step 1: Gather Your Supplies

Before you begin, make sure you have everything you need. This will save you time and frustration later on. Here's a list of essentials:

  • New Shower Arm Diverter: Crucial, obviously! Consider a high-quality model like the AquaBliss Deluxe Shower Arm Diverter. Its durable construction and easy-to-use lever make installation a breeze, and it provides excellent water flow to both your showerhead and handheld shower.
  • Adjustable Wrench: For loosening and tightening connections. One with a rubber grip is ideal to protect the finish of your shower components.
  • Teflon Tape (Plumber's Tape): Essential for creating watertight seals. Don't skimp on this!
  • Clean Towel or Rag: To protect surfaces and wipe up any drips.
  • Optional: Plumber's Putty: Can be used for additional sealing if needed.

Step 2: Turn Off the Water Supply

This is the most important safety step! Locate the shut-off valve for your shower. It's usually located near the shower itself, or in the basement or utility room. Turn the valve clockwise until the water stops flowing. To double-check, turn on the shower briefly to make sure no water comes out.

Pro Tip: If you can't find a specific shut-off valve for the shower, you might need to turn off the main water supply to your house. Just make sure everyone knows before you do!

Step 3: Remove the Old Showerhead (If Applicable)

If you already have a showerhead installed, you'll need to remove it. Using your adjustable wrench, carefully loosen the connection where the showerhead attaches to the shower arm. Be gentle, as you don't want to damage the shower arm. Once it's loose enough, you should be able to unscrew it by hand. Clean the threads of the shower arm with a towel.

Step 4: Prepare the Shower Arm Threads

This step is crucial for preventing leaks. Take your Teflon tape and wrap it clockwise around the threads of the shower arm. Overlap the tape slightly with each wrap, and apply about 3-4 layers. This will create a nice, thick seal.

Why Teflon Tape Matters: Teflon tape acts as a lubricant and a sealant. It fills in any tiny imperfections in the threads, creating a watertight connection.

Step 5: Install the Shower Arm Diverter

Now for the main event! Carefully screw the shower arm diverter onto the shower arm, rotating it clockwise. Tighten it by hand until it's snug. Then, use your adjustable wrench to give it another quarter turn to secure it. Be careful not to overtighten, as this could damage the diverter or the shower arm. Make sure the diverter is oriented in the direction you want your handheld shower to point.

Choosing the Right Diverter: When selecting your shower arm diverter, consider the Angle Simple Angle-Adjustable Diverter Valve. It features a swivel ball connection, allowing you to adjust the angle of the handheld showerhead for optimal positioning. This is a significant advantage, especially if you have limitations in the bathroom's layout or want greater control over water flow direction.

Step 6: Attach the Showerhead and Handheld Shower

Attach your existing showerhead to one of the outlets on the shower arm diverter. Again, use Teflon tape on the threads and tighten it securely with your wrench. Then, attach the hose for your handheld shower to the other outlet. Many handheld showers come with their own mounting bracket, which you can install on the wall using screws or suction cups.

Tools for the Job: We recommend using a high-quality handheld showerhead like the Waterpik PowerSpray+. Its powerful spray patterns and easy-to-grip handle make it a pleasure to use, and the included hose is flexible and durable. This showerhead, paired with your brand new shower arm diverter, will bring additional convenience and comfort to your showering experience.

Step 7: Turn the Water Back On

Slowly turn the water supply back on. Check all connections for leaks. If you see any leaks, tighten the connections slightly with your wrench. If the leaks persist, you may need to remove the connections, apply more Teflon tape, and re-tighten.

Step 8: Test the Diverter

Once you're confident that there are no leaks, test the shower arm diverter. Use the lever or knob on the diverter to switch between your main showerhead and the handheld shower. Make sure the water flows smoothly and consistently from both outlets.

Step 9: Enjoy Your New Shower Setup!

Congratulations! You've successfully installed a shower arm diverter. Now you can enjoy the convenience of a dual-showerhead setup. Customize your showering experience with ease and enjoy the versatility of having both a fixed showerhead and a handheld option.

Here are few things I've learned over the years with these:

Pro-Tip 1: Use a thin rubber washer inside the connections for added leak protection. This works especially well with older shower arms that might have slightly damaged threads.

Pro-Tip 2: If your shower arm is old and corroded, consider replacing it entirely. This will make the installation of the shower arm diverter much easier and prevent future leaks. Get a chrome one for the best look, it will match the shower arm diverter.

FAQ 1: What if the diverter is hard to turn?

Sometimes, brand-new diverters can be a little stiff. Try lubricating the lever or knob with a small amount of silicone grease. If it's still difficult to turn after a few uses, contact the manufacturer.

FAQ 2: Can I use a shower arm diverter with low water pressure?

Yes, you can, but keep in mind that the water pressure will be divided between the two showerheads when both are in use. Look for a shower arm diverter with a high flow rate to minimize any pressure loss. You want to enjoy two shower heads, not some drizzly mess.

FAQ 3: How often should I replace my shower arm diverter?

The lifespan of a shower arm diverter depends on the quality of the materials and the frequency of use. Generally, you can expect a good quality diverter to last for several years. If you notice any leaks, cracks, or difficulty in turning the lever, it's time to replace it.

FAQ 4: What is the best position for mounting a handheld showerhead?

The best position for mounting a handheld showerhead depends on personal preference and the layout of your shower. Some people prefer to mount it high up on the wall, while others prefer a lower position. Experiment with different positions until you find the one that works best for you.
