Dual shower heads stand for ease of use and convenience, however, if you have never used one, you may likely thing how to install a dual shower head? what would you need? is it costly? You name it.

In this article, I will give my best to help you learn how would you install a dual shower head without hiring a professional to do the job for you, since humans learn throughout their whole life, and knowing this skill will help you save money!

First things first.

Inspect Your Water Source

Considering the fact that our households use municipal water, the average output may approximately be 5 gallons per minute, sometimes this is less or more. So, an average shower head would use around 5 GPM ( gallons per minute), hence, if you opt to install dual shower head system, each shower head will use 2.5 GPM, along with some loss of pressure.

If you really face difficulties with loss of pressure, I would advise you to upgrade your pump or add a water storage tank that may increase the GPM to at least 10.

Check Your Plumbing Pipe Size

As you may already know, plumbing pipes are available in a wide variety of sizes. In general, water that comes into your house may pass through a 3/4-inch or 1-inch supply line. As the water flows, it shrinks to 1/2-inch pipes, and by default, the drop in size can result in 75% loss of pressure and volume. That’s why,I’d advise you to upgrade your shower valves to handle at least 3/4-inch supply.


Prior to installation, do not forget to begin the process by turning off the water to avoid any leaks or undesirable situations.

Once this is ensured, try to remove your old shower head, and remove any leftover because by doing this, you will leave an clean space for your new shower head. Also, if you recognize a buildup of rust, clean it immediately.

The next step is to install the base valve, and keep in mind that you should wrap the shower arm’s that connects threads in new plumbing tape because you will prevent occasional leaks.

Done? Alright, let’s move on. Now wrap the threads of the valves in plumber’s tape and make sure that you’ve tightened them by using a cloth and once again, before you proceed any further, try to clean the area as much as possible.

Finally, connect the latter mobile shower by screwing in the rope pipe, however, try to ensure that you have enough plumber’s tape on each of the connecting threads.

The last step is to turn the water on and test whether water comes through your shower heads, and if by any chance, you recognize a leak, try to apply more plumber’s tape and tighten as much as you can.
