Before You Begin
If the existing showerhead is an old unit with the pivot ball as part of the shower arm, the arm would need to be replaced first, so that would add to the time and cost.
Most hand shower bars come with screws and anchors for a shower with tile walls, if yours is fiberglass or acrylic, contact the manufacturer for what's required.
Step 1 : Remove old shower head
Hold the shower arm and remove the existing shower head by turning it counterclockwise with an adjustable wrench. Thoroughly clean the threads on the existing shower arm.
Step 2 : Mark the location of the mounting holes
Remove the decorative screw covers from the wall bar end pieces. Then position the bar so the hand shower may be adjusted at a convenient height for household members. Mark the location of the mounting holes on the wall. Then put the wall bar away in a safe location.
Be careful not to plan the location for the wall bar directly behind the shower arm and valve. A water line may be located there and may be damaged while drilling the mounting holes.
Step 3 : Install wall anchors
Drill holes through the shower wall and install the anchors. Use silicone sealant to seal the opening around the anchors.
Step 4 : Attach the wall bar
Install the wall bar to the wall using the hardware (screws and metal washers) that came with the wall bar. Reinstall the decorative screw covers.
Step 5 : Assemble the hose and shower arm
Wrap the shower arm threads with 2-3 layers of thread tape. Screw the backflow preventer to the shower arm and then wrap its threads with thread tape. (A backflow preventer, or vacuum breaker, is required by many local building codes to protect your drinking water from back siphonage. After using the hand shower, some dripping may occur from the vent holes at the bottom. This is normal and demonstrates that it is working properly.
Step 6 : Complete the assembly
Feed the hose through the hand shower holder. Lower the hand shower until the hose end is seated firmly in the holder. Then add the soap dish holder.
