A popular choice for modern bathrooms, concealed shower valves create a sleek and elegant look by hiding most of the plumbing behind the wall, leaving only the control panel visible. Installing a concealed shower valve requires careful preparation, precision, and the right tools.

1. Tools and Materials You’ll Need

• Concealed shower valve kit

• Adjustable wrench

• Screwdrivers

• Drill and hole saw

• Pipe cutter

• Spirit level

• PTFE (plumber’s) tape

• Silicone sealant

• Copper or PEX piping (depending on plumbing system)

2. Preparation and Planning

1. Turn Off Water Supply: Shut off the main water supply before starting.

2. Mark Position: Decide where the valve will be installed. Typically, the valve is placed at a comfortable height of 100–120 cm (40–48 inches) from the floor.

3. Wall Cavity Space: Ensure the wall cavity has enough depth (usually 70–100 mm) to accommodate the concealed valve.

3. Create the Opening in the Wall

• Use a drill and hole saw or cutting tool to make an opening in the wall large enough for the valve housing.

• The cut must be precise to fit the mounting box or valve unit securely.

4. Install the Valve Body

1. Position the valve body into the prepared cavity.

2. Use a spirit level to ensure the valve is perfectly aligned.

3. Secure it firmly to the wall studs or backboard using the provided brackets or screws.

5. Connect the Water Supply Pipes

• Attach hot and cold water supply lines to the respective inlets on the valve body.

• Wrap PTFE tape on threaded joints to prevent leaks.

• Tighten connections with a wrench, ensuring no cross-threading.

6. Connect Outlet Pipes

• Depending on the shower setup, connect outlet pipes to the showerhead, Hand Shower, or body jets.

• Ensure each outlet is correctly aligned and secured.

7. Seal and Pressure Test

1. Turn the water supply back on.

2. Test for leaks by running both hot and cold water through the valve.

3. Check that water pressure and temperature mix correctly.

4. Seal the wall cavity with backer board and waterproofing material if necessary.

8. Attach Trim Plate and Controls

• Once the wall is tiled and finished, install the trim plate over the valve.

• Attach the control handles or knobs.

• Apply a thin layer of silicone sealant around the edges to ensure a watertight seal.

9. Final Testing

• Turn on the valve and test all functions, including switching between outlets if it’s a multi-function valve.

• Ensure smooth handle operation, correct temperature control, and stable water flow.
