Understanding Mixer Showers

Before we dive into the installation process, let's first understand what mixer showers are and why they're worth considering.

What Is A Mixer Shower?

A mixer shower is a type of shower that blends hot and cold water to provide a consistent and comfortable water temperature. Unlike electric showers that heat water on demand, mixer showers rely on your existing hot and cold water supplies. They are known for their precise temperature control and can be a fantastic addition to any bathroom.

Now that we have a basic understanding, let's gather the tools and materials required for the installation.

Tools And Materials

Here's a list of the essential tools and materials you'll need to install a mixer shower:

Tools:

  1. Adjustable wrench
  2. Screwdrivers (flathead and Phillips)
  3. Pipe cutter or hacksaw
  4. Spirit level
  5. Drill and bits
  6. Pencil
  7. Tape measure
  8. Adjustable spanner
  9. PTFE tape (plumber's tape)
  10. Tile cutter (if necessary)
  11. Safety goggles and gloves

Materials:

  1. Mixer shower unit
  2. Wall brackets and fixings
  3. Copper pipes or flexible hoses
  4. Compression fittings
  5. Wall plugs
  6. Screws
  7. Tile adhesive and grout (if tiling is required)
  8. Silicone sealant
  9. Wall-mounted shower head and hose
  10. Isolation valves (if not already present)

Now that you've gathered everything you need, let's proceed to the installation steps.

Pre-Installation Preparation

1. Check Water Pressure And Suitability

Before installing a mixer shower, it's crucial to check the water pressure in your home. Mixer showers work best with a minimum pressure requirement, typically around 0.1-0.5 bar. If your water pressure falls within this range, you're good to go. However, if your pressure is significantly lower, you might need a shower pump to boost it.

2. Determine The Shower Location

Decide where you want to install your mixer shower. Ensure it's a comfortable and accessible location that allows easy access to the hot and cold water supplies. It's also essential to consider the showerhead's height to accommodate different users.

3. Isolate The Water Supply

Locate and shut off the water supply to the bathroom or the specific water lines you'll be working on. This step is crucial for your safety and to prevent any water leakage during the installation.

With the pre-installation preparations in place, let's move on to the installation steps.

Installing The Mixer Valve

The mixer valve is the heart of your mixer shower, where the hot and cold water are blended to your desired temperature. Here's how to install it:

1. Mark The Installation Height

Using a spirit level and a pencil, mark the desired height for your mixer valve on the wall. This height should be comfortable for you and anyone using the shower. Typically, mixer valves are installed around chest to shoulder height.

2. Attach The Wall Brackets

Install the wall brackets for your mixer valve at the marked height. Use wall plugs and screws to secure them firmly to the wall. Ensure they are level and properly aligned.

3. Connect The Pipes

Next, it's time to connect the hot and cold water supplies to the mixer valve. If you have existing copper pipes, use compression fittings to make the connections. If you're using flexible hoses, attach them securely. Apply PTFE tape to the threads to ensure a watertight seal.

4. Mount The Mixer Valve

Slide the mixer valve onto the wall brackets and secure it in place using the provided fixings. Double-check that it's level and at the desired height.

5. Fit The Cover Plate

Most mixer valves come with a cover plate to conceal the pipework and create a neat finish. Attach the cover plate to the valve, ensuring it's properly aligned and secure.

With the mixer valve in place, you're one step closer to enjoying your new mixer shower. Now, let's move on to connecting the shower head and hose.

Connecting The Shower Head And Hose

The shower head and hose assembly is the final piece of the puzzle. Here's how to connect them:

1. Attach The Shower Head Holder

If your shower head holder requires wall mounting, use the provided fixings to attach it securely. Ensure it's at a height that suits your preferences.

2. Connect The Hose

Attach one end of the shower hose to the mixer valve's outlet. Ensure it's tightened securely to prevent any leaks.

3. Mount The Shower head

Slide the shower head onto the holder, and you're almost done. Make sure it's secure but not overly tight.

Testing And Adjusting

Before you can enjoy your newly installed mixer shower, it's essential to test it and make any necessary adjustments:

  1. Turn on the water supply.
  2. Gradually open the mixer valve to let water flow.
  3. Check for any leaks around the valve, connections, or shower head.
  4. Adjust the mixer valve to achieve your desired water temperature.
  5. Ensure that the water pressure is adequate for a comfortable shower.

If everything checks works fine, congratulations! You've successfully installed a mixer shower.

Maintenance And Troubleshooting

To keep your mixer shower in excellent condition, consider these maintenance tips:

Regular Cleaning

Cleaning your shower head and hose is a simple yet effective way to ensure consistent water flow and prevent clogs. Over time, mineral deposits, soap scum, and debris can accumulate inside these components, restricting the flow of water and affecting your shower's performance.

Descaling

Descaling is a vital maintenance task that focuses on the inner workings of your mixer shower—the valve. Over time, especially in areas with hard water, mineral deposits can accumulate inside the valve. These deposits can obstruct water flow, reduce pressure, and even affect the accuracy of temperature control.

For any issues or troubleshooting, refer to the manufacturer's instructions or seek professional assistance.

Installing a mixer shower can be a rewarding DIY project that enhances your bathroom experience. By following the steps outlined in this guide and ensuring proper maintenance, you'll enjoy the benefits of a comfortable and precisely controlled shower for years to come.
