But sometimes, unexpected accidents can sour the mood of an otherwise great experience. A leaking shower faucet will do just that, don’t worry because we’ll tell you how to replace an RV shower faucet.

Lucky for you, replacing RV shower faucet is easy as pie. We’ll go over the tools you need and will guide you step by step.

What You Need to Prepare


  • A brand-new RV shower faucet replacement kit
  • A Phillips screwdriver, preferably with a length of 8-inches
  • A pair of pliers
  • A box cutter

Step 1: Shut off your water supply


First thing first, make sure that the water supply is properly turned off. Turn off your water pump if you’re getting water from the RV’s water tank. If you’re getting it from somewhere else, simply disconnect your RV from the source.

Then, turn on the shower and other faucets until no water comes out.

Step 2: Find access panel of the shower faucet and disconnect the water hoses

Most RV’s have a shower access panel located at the rear of the RV. If you cannot find it, check your RV’s model and specification.

If you find out that your RV does not have an access panel, skip this step and move to the next one.

If you can find the panel here’s what you should do:

  • Pop the panel open. Looking inside, you’ll see a pair of hoses connected to the back of the motorhome shower faucet. These are the hoses supplying hot and cold water to your shower.
  • Unscrew the nuts securing it and detach both hoses. Use your pliers so you can easily uncouple the hoses.
  • Now that the hoses are removed, head on inside your RV.

Step 3: Dismount the mounting plate


If your RV is without the access panel, don’t worry and continue forward.

Inside your bathroom, you’ll find the mounting plate of your trailer shower faucet. Remove the shower hose first before detaching the mounting plate.

The mounting plate will be caulked to the wall, making its removal difficult. Use your box cutter to cut through the sides of the mounting plate. This will free it up and allow you to remove it easily.

Afterward, you will use your screwdriver to undo the screws on the sides of the mounting plate. Once you’ve removed the screws, you can dismount the mounting plate.

Once you’ve removed the mounting plate, you can unfasten the nuts securing the body of the shower faucet and remove RV shower faucet.

Step 4: Install the new faucet


Attach the new shower faucet to the mounting plate, and secure it using the nuts it came with. Reconnect and secure the water hoses to the shower faucet.

Place the mounting plate in its original place and secure it with its screws. Make sure that the mounting plate is leveled and placed just right.

Once the mounting plate is safe and secured, finish it by reattaching the shower hose to the shower faucet.

Step 5: Check all your connections and hose

Now that you’ve installed your new shower faucet, it’s time to switch on your water source and check your connections and hoses.

Ensure thoroughly inspect the edges of your new shower faucet’s mounting plate and knobs. Keep an eye out for any leaks. This goes for water hoses as well.

If you notice an RV shower faucet leaking, use sealants on leaks or tighten the nuts and bolts securing your water hoses.


How do I take apart my RV shower faucet?

The first thing you’re going to do is figure out your RV’s parts diagram and determine where its access panel is. Then, switch off your water pump or disconnect your RV from its water source.

Replace the old one with the new one, put the mounting plate back, connect the water hoses, and switch on your water supply. Easy, right?
