Three handle tub shower faucet is an essential item in any bathroom. However, it can be oxidized by constant humidity. Therefore, the faucet’s service life is negatively affected, and you have to remove it right away. Fortunately, replacing the shower is very simple; you can do it yourself without calling a maintenance specialist. 

The article below will reveal the fastest way about replacing an old 3 handle tub shower faucet; let us pave the way for you with five easy- done stages!

Replacing an old 3 handle tub shower faucet – what to do? 

Step 1: Shut off the water 

Locking the water valve in any direction is a must. This can be done by finding the two symbols on the valve, indicating which approach should be closed. 

However, in case you are working in the low-light condition, knowing which direction to turn the water valve can cause you some trouble. So, make sure you remember the direction of opening and locking the valve clearly.

If you use the rotary kind, lock the valve clockwise until it cannot be rotated, then stop. Next, open the precursor in the opposite direction.

For water valves that are wipers, you need to use a simple operation of turning the lever hand clockwise to lock and open in the opposite direction.

Step 2: Disassemble the shower

The general structure of a shower includes the following parts: showerhead, cord, and core. How to remove them?


In case that a damaged core causes a fault such as a leak, you need to buy the standard core with components that are compatible with your current shower. The product must be synchronous to not damage the using process due to the faulty installation components. 

 In order to save the cost, it is best to choose genuine, branded, and good quality products that are much appreciated so that you know better about the product.

Using genuine accessories will also help lengthen the product’s lifespan, preventing you from replacing parts regularly.


With the old showerhead removed, you may notice some excess material in the form of dirt, leftover rubber gaskets, or duct tape around the pipes. Remove them all to make your new shower clean.


When you shower, accidentally pulling on the water cord can cut the water cord and make the shower inoperable. To fix this problem, you need to buy a new set of water lines, then remove the old shower cord and install a new one.

Step 3: Put the new stems 

This step is more complicated than the previous ones, so we have listed what you should do in the order below:

  • Put the new stems into the valves and tighten them with the tub socket.
  • Cover the tub with several layers of waterproof tape. 
  • Use your finger to smooth the ice along the vein of the water pipe.

Step 4: Turn the water back on

Two symbols will mark hot and cold showers on the root: the red dot represents hot water, blue dot represents cold water. 

When you want to use any water temperature, push the lever to that side and then lift the controller. It would be helpful to slowly move the cold to the hot side to avoid the sudden flow of hot water, causing burns.

Step 5: Double-check

Turn on the showerhead, look, and feel around the hose connections for leaks. If there is nothing left, then you have successfully replaced your bathroom with a new shower.
