Upgrading your RV’s bathroom fixtures can be a functional necessity or a way to enhance your RV’s style and comfort. Whether you’ve purchased a used RV that needs refreshing or simply want to give your older model a modern touch, upgrading your faucets, showerheads, and other fixtures can make a significant difference.
Why Upgrade Your RV Bathroom Fixtures?
- Improve Quality – Stock fixtures may not always be the most durable or stylish.
- Modernize Your RV – A few updates can make an older RV feel brand new.
- Increase Comfort – Upgraded fixtures can enhance water flow, usability, and aesthetics.
- Customization – Create a space that better fits your personal taste and needs.
Can You Upgrade Bathroom Fixtures in Your RV?
Yes! Upgrading bathroom fixtures in an RV is absolutely possible—and it can be an easy DIY project. Many manufacturers offer different trim levels, so even if you didn’t buy the most luxurious model, you can still enhance it with higher-end fixtures to get the best of both worlds.
Even small changes, like swapping out a basic showerhead for a high-pressure model or replacing a plastic faucet with a sleek metal one, can turn a standard RV bathroom into a more stylish and comfortable space.
Stay tuned for tips on choosing the right fixtures and installing them with ease!
Check Your RV Warranty Before Upgrading Fixtures
When purchasing an RV, you don’t always get the chance to test the water flow or assess how well the fixtures fit your daily needs. It’s only after your first few uses that you might realize the kitchen faucet is too low, making it difficult to fill large pots, or that other fixtures don’t function quite as expected.
Why Your Warranty Matters
Before replacing faucets, showerheads, or other fixtures, check your RV warranty to ensure that modifications won’t void your coverage. Some manufacturers require all upgrades to be done by authorized dealers to maintain the warranty. If you’re unsure about the terms, contact your RV dealer or manufacturer before making any changes.
What If You Bought a Used RV?
Even if your RV is pre-owned, some warranties may still be in effect—especially on newer models. Always review any existing warranties before making modifications. However, if your RV is no longer under warranty, you have full control over upgrades, as long as they comply with DMV regulations and safety standards.
Taking these precautions ensures you can upgrade your RV confidently without risking warranty coverage or creating potential safety issues.
Essential Tips for Upgrading Your RV Bathroom Fixtures
Upgrading your RV’s shower faucets, sink faucets, and outdoor shower units can improve both function and style. Whether replacing worn-out parts or upgrading for a fresh look, these tips will help ensure a smooth installation process.
Finding Replacement Fixtures
- Search online for RV replacement fixtures, as many websites and RV stores carry compatible parts.
- If you want the exact same fixture, contact your RV manufacturer to check for availability.
- When switching to a different model, verify that dimensions, pipe lengths, and threading match your existing setup. You may need adapter pieces for a proper fit.
Step 1: Turn Off the Water Supply
Before removing any fixture, always shut off the water source:
- If connected to city water, turn off the main supply.
- If boondocking and using the fresh water tank, turn off the water pump.
- Open the fixture’s spigots to drain any remaining water from the lines.
Step 2: Prevent Water Damage
- Keep rags, towels, sponges, or a small bucket nearby to catch any residual water.
- After installation, check for leaks periodically—water damage in an RV can be costly and difficult to repair.
Step 3: Carefully Remove the Old Fixture
- Take notes or photos during removal so you can reverse the process when installing the new fixture.
- If your RV is older, consider replacing water supply hoses while you’re at it for added reliability.
Step 4: Install the New Fixture
- Use pipe thread tape and plumber’s putty where needed to prevent leaks.
- Tighten fittings securely, but don’t overtighten, as many RV plumbing components are plastic and can crack.
- Double-check that everything is properly aligned and level—an extra set of hands may help with this step.
Step 5: Test for Leaks
- Once everything is installed, slowly turn the water back on and check for leaks immediately.
- If no leaks are present, replace any access panels or doors and secure them properly.
Accessing Your Fixtures
- Some RVs have exterior access panels, while others require access from inside the RV (e.g., under the sink).
- If space is tight, be patient—RV plumbing access can be tricky.
- If unsure, ask an RV service technician for guidance or watch YouTube tutorials for step-by-step demonstrations.
Final Thoughts
If you’ve done plumbing work in your home, you can likely handle an RV fixture replacement. However, always double-check fittings and water flow to avoid costly leaks. If needed, get help from a friend or professional to ensure a smooth installation.
Now, let’s go over some common upgrade scenarios.
How to Replace a Shower or Sink Faucet in Your RV
Replacing a shower or sink faucet in your RV follows a similar process, whether it’s for the kitchen or bathroom. This guide focuses on bathroom fixture replacements, ensuring you get the job done efficiently and leak-free.
Step 1: Prepare for Replacement
- Before starting, confirm that your new fixture matches the dimensions and connections of the old one. If it’s a different model, ensure you have any necessary adapters.
- Turn off your water source and pump before removing any plumbing components.
- Take photos or notes during disassembly to make installation easier.
Step 2: Remove the Old Faucet
- Drain the water lines by opening both hot and cold valves.
- Disconnect the hot and cold water lines and drain any remaining water into a bucket or wipe with a towel.
- If PEX lines are present, they may be color-coded (red for hot, blue for cold). If not, label them for future reference.
- Loosen the couplers securing the faucet to the sink or shower wall.
- If working on a shower faucet, disconnect the shower wand assembly if necessary.
- If replacing a sink faucet, detach the drain stopper and note its length. Some RV sinks may use manual plugs instead of pull/push stoppers.
- Once the couplers are removed, lift out the faucet assembly and clean the surrounding area.
Step 3: Install the New Faucet
- Apply plumber’s putty if the original installation used it.
- Insert the new faucet and align it properly.
- Secure it in place by tightening the collar couplings.
- Reconnect the hot and cold water lines, using thread tape (wrapped clockwise) for a leak-free seal.
- Double-check all fittings for tightness before turning the water back on.
Step 4: Test for Leaks
- Slowly turn the water back on and check for leaks.
- Open both hot and cold valves and inspect all connections.
- If everything is dry, your new faucet is successfully installed!
Note: The process for replacing a kitchen sink faucet is nearly identical.
Replacing an Outdoor Shower on Your RV
If your RV has an outdoor shower, the replacement process is slightly different but still straightforward.
Step 1: Locate and Access the Shower Unit
- Determine where your outdoor shower is installed and how to access it from inside your RV.
- If you’re installing a new outdoor shower, choose a location with proper plumbing access.
Step 2: Remove the Old Outdoor Shower Unit
- Turn off the water supply and pump.
- Open the valves to drain the water lines, marking hot and cold if not already labeled.
- Remove the hoses and check if they need replacement.
- Some outdoor showers store the hose and wand inside the compartment.
- Others require detaching the hose and wand after each use for storage elsewhere.
- Once detached, loosen the couplers holding the faucet unit in place.
- Remove the entire faucet assembly, clean the area, and prepare for installation.
Step 3: Install the New Outdoor Shower Unit
- Insert the new unit and align it properly.
- Secure it in place by tightening the couplers.
- Attach the water hoses, using pipe thread tape if needed.
- Turn the water back on and check for leaks.
Considering an Upgrade?
If your outdoor shower requires frequent assembly and disassembly, consider upgrading to a larger built-in unit.
- Some models require expanding the existing opening or installing a deeper unit that sits further into the RV.
- If modifications seem complex, consult an RV dealership service department to ensure proper installation.
By following these steps, you can successfully replace or upgrade your RV’s bathroom and outdoor shower fixtures, improving both functionality and convenience.
Installing an Outdoor Shower in Your RV
If your RV doesn’t already have an outdoor shower, installing one can be a fantastic upgrade. It provides convenience for washing off dirt, sand, or pets before entering your RV. However, this installation requires cutting into your RV’s exterior, so careful planning is essential.
Step 1: Choose the Installation Location
- Find a suitable spot for your new outdoor shower. It should have easy access to both hot and cold water lines inside your RV.
- Many outdoor shower kits come with weatherproofing materials to ensure a watertight seal. You will likely need caulk to seal any seams and prevent leaks.
Step 2: Tap into Your Water Lines
- Locate your existing water lines inside the RV.
- Determine where to cut the lines and install a tee fitting to create a new connection for the outdoor shower.
- Use SharkBite fittings or threaded connectors for a secure attachment. (If you’re unfamiliar with SharkBite fittings, a quick Google search will explain their benefits.)
- Before cutting, turn off the water supply and drain the lines by opening the faucets.
- Once the tee fittings are installed, run the new water lines to the shower location and attach the appropriate connectors.
- Connect the shower fixture’s hot and cold water lines to your new plumbing.
Step 3: Cutting the Opening for the Shower Unit
- The next step is cutting a hole in your RV’s exterior wall to install the shower compartment.
- Follow the measure twice, cut once rule (or even three times, just to be sure!).
- Use a template (often included with the shower kit) to outline the cut area. You may also place it inside the RV first to check for obstructions.
- Check for wiring, insulation, or other water lines before cutting.
- Drill pilot holes in all four corners of your outline, then move to the exterior and align the template with these holes.
- Use a metal-cutting saw blade to carefully cut the opening.
Step 4: Securing the Shower Compartment
- Once the opening is cut, you’ll likely need to frame the inside edges to provide structural support.
- Use wood or metal framing, depending on the RV’s construction.
- Insert the outdoor shower assembly, making sure it fits snugly and is properly aligned.
- Seal around the edges with weatherproof caulk to prevent water leaks.
- Secure the shower compartment with screws.
Step 5: Connect Water Lines and Test for Leaks
- Install the faucet assembly, ensuring it is level and properly aligned.
- Attach the couplers and water hoses, using pipe thread tape to prevent leaks.
- Turn on the water supply and pump, then check for leaks at all connections.
- If everything is dry, attach the shower hose and wand.
Professional Help & Warranty Considerations
- If this installation feels too complex, consult your RV dealership’s service department. They may offer installation services and provide a warranty on their work.
- Before modifying your RV, check your manufacturer’s warranty. Some warranties may become void if major modifications are made.
Final Thoughts: Making Your RV Your Own
Adding an outdoor shower is just one of the many ways you can customize your RV to better fit your lifestyle. RV supply stores and RV shows are great sources of design inspiration. If you see a fixture you love, take photos for reference.
Weight Considerations
Many factory-installed RV faucets and showers are made of lightweight plastic to reduce overall vehicle weight. If you’re upgrading to metal fixtures, keep in mind that added weight affects fuel efficiency and towing capacity.
With the right tools and planning, you can turn your RV into a true home on wheels—customized exactly the way you want it.
