For most of us, taking a hot shower is part of our daily routine. Because we depend on it daily, it’s important that your shower is installed to withstand high water pressure without leaking. Whether you're undertaking a major bathroom renovation or simply updating your showerhead, you're probably stuck wondering how to connect your shower plumbing. Our expert plumbers at Outright Plumbing have put together this helpful guide to walk you through the process step by step.

It’s safe to say Outright Plumbing knows its way around a bathroom; we’ve delivered expert plumbing solutions for years! With the right tools and our industry knowledge, your shower will be flowing in no time. Regardless of whether you want to do this yourself or call in a professional, it pays to understand what the process entails. That way, you can stay informed at all times. Our team has broken the task into simple steps suitable for any homeowner to follow.

Things you’ll need for your DIY job

It's best to gather everything you need to complete your shower plumbing before you start. Making sure you have all the correct tools and parts is essential to avoid hiccups along the way.

To install your shower, you will need:

  • Pencil
  • Measuring tape
  • Drywall saw or hole saw (depending on your wall material)
  • Wrench
  • Pipe fittings
  • Plumber’s tape
  • Shower parts: Showerhead, arms, and valve

If you are missing any parts, now’s the perfect time to run down to your local hardware store.

Step 1: Planning your shower plumbing installation

Before you get started, it’s crucial to plan the layout of your shower – knowing where your water supply lines and drainage will run is essential to avoid mistakes. An improperly installed or misaligned shower could easily cost you more than you save with a DIY installation, leading to timber rot, mould growth, structural failure, and water pooling. Always understand the risks associated with DIY plumbing jobs and be realistic about your skill level. 

Take time to map out your bathroom layout and where the shower will be positioned. The shower drain and water lines need to be aligned properly to ensure efficient water flow and avoid any drainage issues down the road.

Step 2: Turn off the water supply

Safety should always come first; shut off your shower's water supply to prevent leaks or water damage. Locate and turn off the main water valve to stop your entire property's water supply. This valve is usually found next to your water meter outside.

After shutting off the water, turn on the shower taps and drain any residual water that’s left in the lines. This not only confirms the shower’s water supply has been successfully shut off but also prevents moisture from interfering with your sealing and installation work in the next steps.

Step 3: Install the shower valve

The shower valve controls water flow and temperature, so installing it correctly is key. Start by marking where the valve will go, ensuring it’s at a comfortable height for users.  Use a measuring tape to do this, and make sure everything is aligned. 

Once marked, saw a hole in the wall for the valve and attach it to the water lines, ensuring the hot and cold water pipes are connected correctly. Use a wrench to securely fasten the valve (but be careful not to overtighten!). 

Step 4: Connect the water supply lines

Now it’s time to connect the water supply lines to the shower valve. You’ll need to solder copper pipes or use PEX pipes, depending on your system. Be sure to measure and cut the pipes to the correct length, then attach them to the valve. Make sure all connections are sealed tight to prevent leaks. If you’re not confident soldering pipes, this is a great time to call Outright Plumbing to ensure everything is done correctly.

Step 5: Install the showerhead and faucet

Next, install the showerhead and faucet. Use plumber’s tape on the threads of the shower arm to ensure a watertight connection. Screw the showerhead onto the arm and secure the faucet in place. Double-check that everything is tight, but don’t overdo it – overtightening can lead to damaged threads or connections.

Step 6: Test the system

Once everything is installed, it’s time to test the system. Turn the water supply back on and check for leaks around the valve, showerhead, and connections. Run the water and test both hot and cold settings. If everything works smoothly, congratulations! You’ve successfully installed your shower plumbing.
