Traveling in an RV offers a unique blend of freedom and comfort. However, like any home, it comes with its own set of maintenance challenges. One such issue that many RV owners face is a shower leak behind the wall.
If not addressed promptly, this can lead to mold growth, structural damage, and other complications. In this article, we’ll explore the common causes of this problem and provide a step-by-step guide to fixing it.
Key Takeaway:
A leaking RV shower faucet behind the wall can be concerning and is typically caused by a few common issues: worn-out seals or gaskets, a cracked valve body, loose connections, or accumulated mineral deposits. Regular inspection and timely maintenance are crucial to prevent potential water damage and costly repairs in your RV. If a leak is suspected, it’s advisable to address it promptly to ensure the longevity and safety of your RV’s interior components.
Common Causes of RV Shower Leaks Behind the Wall
Addressing a leaking RV shower requires a systematic approach. Depending on the cause of the leak, the repair process can vary. Here’s a more detailed breakdown of the steps for each type of fix:
- Identify the Source of the Leak:
- Visual Inspection: Start by checking for visible signs of moisture, mold, or water damage around the shower area.
- Water Test: Turn on the shower and observe where the water might be escaping. This can help pinpoint the leak’s location.
- Wall Inspection: If necessary, carefully remove a section of the wall to inspect the plumbing and other components behind it.
- Fix Plumbing Issues:
- Tighten Connections: Over time, connections can become loose. Ensure that the connections between the showerhead, faucet, and pipes are tight.
- Replace Damaged Parts: If you find any corroded or damaged pipes or connections, replace them. It’s essential to use RV-specific parts or those recommended by the manufacturer.
- Seal Joints: Use plumber’s tape or joint compound to ensure all threaded joints are sealed properly.
- Repair or Replace Tiles and Grout:
- Remove Damaged Tiles: Carefully chisel out any cracked or loose tiles without damaging adjacent ones.
- Apply New Tiles: Once the area is clean and prepped, set new tiles using a waterproof adhesive. Ensure they align with the existing tiles.
- Re-grout: Fill the spaces between tiles with fresh grout. Make sure to seal the grout after it has dried to prevent moisture penetration.
- Address Shower Pan Issues:
- Inspect for Cracks: Check the shower pan for any visible cracks or damage.
- Seal Minor Cracks: For smaller cracks, use a waterproof sealant or epoxy designed for shower pans.
- Replace the Shower Pan: If the pan is significantly damaged, it’s best to replace it entirely. Ensure the new pan is sealed and connected properly to prevent future leaks.
- Re-caulk and Seal:
- Remove Old Caulk: Use a caulk removal tool or a utility knife to carefully remove deteriorating caulk from around the shower.
- Clean the Area: Before re-caulking, clean the area thoroughly with a mixture of water and white vinegar to remove any mold or mildew.
- Apply New Caulk: Using a caulking gun, apply a bead of waterproof caulk around the shower. Smooth it out with a caulk smoothing tool or your finger for a watertight seal.
- Test the Shower:
- Check for Leaks: After making repairs, turn the water back on and monitor the shower for any signs of leaks.
- Monitor Over Time: Sometimes, leaks may not be immediately apparent. Keep an eye on the repaired areas over several days to ensure the problem is fully resolved.
- Replace the Wall (if necessary):
- Choose the Right Material: If you had to remove a section of the wall, replace it with material suitable for wet environments, ensuring it matches the rest of your RV’s interior.
- Seal Edges: Once the new wall section is in place, seal its edges to prevent moisture from getting behind it.

- Address Shower Pan Issues: If the shower pan is damaged, it might need to be replaced. If it’s a sealing issue, clean the area thoroughly and apply a new layer of sealant.
- Re-caulk and Seal: Remove old, deteriorating caulk from around the shower. Clean the area thoroughly and apply a fresh bead of waterproof caulk. Make sure to smooth it out for a watertight seal.
- Test the Shower: Once repairs are done, turn the water back on and test the shower. Check for any signs of leaks.
- Replace the Wall (if necessary): If you had to remove a section of the wall to identify or fix the leak, replace it once you’re sure the leak is fixed. Ensure the wall material is suitable for wet environments.
When considering access points it’s best to access the plumbing from the backside of the shower wall. Only if your RV layout permits you to of course. In some cases, you may have to access the shower plumbing through the inside of the shower. Do not cut vinyl panels if you plan on reusing them, try to remove them first.
Finding the Right RV Service Provider
Finding a reliable RV service provider to address a shower leak behind the wall is essential for a long-lasting solution. One of the best ways to start your search is by seeking recommendations from fellow RV owners, friends, or family members who might have faced similar issues.
If personal recommendations aren’t available, turning to the internet can be invaluable. Websites like RV Service Reviews offer insights and reviews from other RV owners. Additionally, online platforms such as iRV2, RV.net, and various RV-centric Facebook groups can be treasure troves of information. You can either sift through previous discussions or post a query asking for recommendations.
Local RV dealerships, even if not your point of purchase, often have service departments or can point you toward trusted local technicians specializing in RV repairs. Once you’ve identified potential service providers, it’s crucial to vet their credentials. Ensure they have the necessary licensing, if required in your state, and peruse reviews or testimonials from previous clients.
When reaching out, don’t hesitate to ask about their experience with RV shower repairs, potential costs, and timelines. Always request a written estimate that details the scope of work, parts, labor costs, and any associated warranties. Lastly, trust your instincts. If something feels off about a service provider or if an offer seems too good to be true, continue your search until you find a professional you’re entirely comfortable with.
