How to install a Bath Shower Mixer

Installing a bath shower mixer is a moderately complex task that requires careful preparation and attention to detail. This type of faucet allows you to switch between filling the bathtub and showering, providing versatility in your bathroom.

Tools and Materials You'll Need:

Before you begin the installation process, gather the necessary tools and materials:

Tools:

Adjustable wrench

Pipe cutter or hacksaw

Pipe wrench

Plumber's tape (Teflon tape)

Spirit level

Screwdrivers (both flat-head and Phillips)

Pliers

Materials:

Bath shower mixer faucet kit

Copper or PEX pipes (if replacing or extending water supply lines)

Compression fittings (if required)

Wall mounting bracket (if not included with the faucet kit)

Wall anchors and screws

Silicone sealant

Installation Steps:

1. Turn Off the Water Supply:

Before starting any plumbing work, turn off the water supply to the bathroom. You can usually find the shut-off valves under the sink or in a utility room. If there are no individual shut-off valves for the bathroom, you may need to shut off the main water supply to the house.

2. Drain the Water:

Open the faucets in the bathroom to drain any remaining water from the pipes. This step is essential to prevent water from leaking out during the installation.

3. Remove the Old Faucet (if applicable):

If you are replacing an existing faucet, use a pipe cutter or hacksaw to carefully cut the water supply pipes connected to the old faucet. Remove the old faucet and any mounting hardware from the wall or bathtub.

4. Prepare the Wall:

If the new bath shower mixer does not come with a wall mounting bracket, attach one to the wall using wall anchors and screws. Use a spirit level to ensure it is level and positioned correctly.

5. Install the Mixer Valve:

Insert the mixer valve into the wall bracket or directly onto the wall if no bracket is used. Connect the hot and cold water supply pipes to the corresponding inlets on the valve. Use compression fittings or solder the connections if you're using copper pipes. Wrap the plumber's tape around the threaded ends of the pipes before attaching them to the valve to ensure a watertight seal.

6. Install the Faucet:

Attach the bath shower mixer faucet to the valve outlet, ensuring it is securely fastened. Use an adjustable wrench to tighten the connections. Be careful not to overtighten and damage the faucet or the valve.

7. Install the Shower Head and Hose:

If your bath shower mixer kit includes a handheld showerhead, attach it to the hose and connect the hose to the faucet's shower outlet. Hand-tighten the connections, and then use pliers to give them an extra snug turn.

8. Test the Water Flow:

Turn on the water supply and test the bath shower mixer to ensure there are no leaks. Check both the bathtub spout and the showerhead to make sure water flows correctly.

9. Seal Around the Mixer Valve:

Use silicone sealant to create a waterproof seal around the mixer valve where it meets the wall. Smooth the sealant with a wet finger to ensure a neat and effective seal.

10. Secure Any Loose Pipes:

If any pipes or hoses are dangling, secure them to the wall using pipe clips or supports to prevent strain on the connections.

11. Adjust and Test Temperature:

If your bath shower mixer has a temperature control handle, adjust it to your desired temperature and test the water again to ensure the mix is correct.

12. Final Check:

Turn off the water supply, and double-check all connections for leaks. Tighten any loose fittings if necessary.

13. Finish Wall Covering:

If you had to cut into the wall to install the bath shower mixer, repair and finish the wall as needed, whether it's patching drywall, tiling, or applying a wall covering.

14. Clean Up:

Clean up any debris or tools from the installation, leaving your bathroom tidy and ready for use.

Installing a bath shower mixer requires careful planning, accurate measurements, and the right tools and materials. By following these steps and paying attention to detail, you can successfully install a bath shower mixer in your bathroom, providing both bathtub filling and showering functionality. If you're unsure about any part of the installation process, consider consulting a professional plumber to ensure a proper and leak-free installation.
