Have you ever dreamed of transforming your cramped, outdated shower into a spa-like retreat, only to be stopped by the confusing maze of pipes behind your walls? You are not alone. Many homeowners hesitate to tackle plumbing projects because they fear causing leaks or damaging their home’s structure. However, with the right preparation and knowledge, learning how to reroute plumbing for the shower head is an achievable DIY project that can significantly increase your home’s value and comfort.
This guide will walk you through the process with clarity and confidence. We will cover everything from assessing your current layout to making the final connections, ensuring you avoid common pitfalls. Whether you are moving a shower head for better ergonomics or installing a new rain shower system, this article provides the roadmap you need.
Is It Difficult to Reroute Shower Plumbing?
The complexity of rerouting shower plumbing depends largely on your home’s construction and the extent of the move. If you are simply extending a pipe a few inches within an open stud wall, the task is moderate. However, if you are moving the shower head to a completely different wall or dealing with concrete slabs, the difficulty spikes significantly.
According to general industry standards, minor plumbing modifications can save homeowners between $150 to $400 in labor costs if done correctly as a DIY project. However, accuracy is paramount. A single misaligned fitting can lead to water damage inside your walls, which is far costlier to repair than hiring a professional initially.
Key Factors Influencing Difficulty:
- Wall Type: Drywall over studs is easier to work with than tile-over-concrete.
- Distance: Moving the fixture less than 12 inches is straightforward; moving it several feet requires more piping and support.
- Access: Do you have access from the back (e.g., a closet or adjacent room)? If not, you will need to cut into the tile or drywall.
What Tools and Materials Do You Need?
Before you swing a hammer, gather the right tools. Using improper tools can strip fittings or crack pipes, leading to immediate failures. For a standard copper or PEX plumbing system, here is your essential checklist.
Essential Tools
- Pipe Cutter: For clean cuts on copper or PEX pipes.
- Adjustable Wrenches (2): One for holding the pipe, one for turning the fitting.
- Stud Finder: To locate framing members safely.
- Drywall Saw or Oscillating Multi-Tool: For cutting access holes.
- Teflon Tape (PTFE) & Pipe Dope: For sealing threaded connections.
- Level: To ensure your new shower arm is perfectly horizontal.
- Soldering Torch (if using Copper): Or crimping tools (if using PEX).
Materials List
| Material | Purpose | Recommendation |
|---|---|---|
| Copper/PEX Pipe | Water supply line | Match existing pipe type for compatibility. |
| Elbow Fittings (90°) | Changing direction | Use sweat fittings for copper; crimp for PEX. |
| Shower Arm | Connects wall to head | Choose length based on new position. |
| Escutcheon Plate | Covers wall hole | Ensures a clean, finished look. |
| Pipe Straps | Securing pipes | Prevents vibration and noise (“water hammer”). |

Step-by-Step: How to Reroute Plumbing for the Shower Head
Follow these steps meticulously. Rushing any stage can compromise the integrity of your plumbing system.
Step 1: Shut Off Water and Prepare the Area
Safety first. Locate your main water shut-off valve or the specific isolation valve for the bathroom. Turn it off and open the existing shower faucet to drain any remaining pressure and water.
- Tip: Place a bucket under the work area to catch residual drip.
- Verification: Ensure no water flows when you turn the shower handle. If it does, the valve is not fully closed or is faulty.
Step 2: Map the New Route
Use a pencil and level to mark the new desired location of the shower head on the wall. Determine the path the pipe will take from the existing supply line to the new location.
- Ideal Height: Standard shower heads are installed at 80 inches (6’8″) from the floor. Rain showers may require 90–96 inches.
- Stud Check: Use your stud finder to ensure your new route doesn’t conflict with structural supports. If it does, you may need to drill through studs (using a hole saw) rather than running pipes along them.
Step 3: Access the Existing Plumbing
If you have access from the back (like a linen closet), remove the drywall there. If not, carefully cut out the drywall or tile around the existing shower arm.
- Caution: If cutting tile, use a diamond blade and wear eye protection. Tile shards are sharp and dangerous.
- Expose the Pipe: Clear enough space to work comfortably, usually a 6×6 inch square around the connection point.
Step 4: Cut and Extend the Pipe
Cut the existing pipe at the point where you want to branch off or extend.
- For Copper Pipes: Clean the ends with emery cloth. Apply flux, fit the elbow or coupling, and solder the joint. Ensure the flame is directed away from any flammable insulation.
- For PEX Pipes: Use a PEX cutter for a square cut. Slide the crimp ring over the pipe, insert the fitting, and crimp securely. Verify the crimp with a go/no-go gauge.
Extend the pipe along your mapped route to the new height. Secure the pipe to the studs every 32 inches using pipe straps to prevent movement.
Step 5: Install the New Shower Arm
At the new location, install a 90-degree elbow facing outward. Screw in the new shower arm.
- Sealing: Wrap Teflon tape clockwise around the threads of the elbow (3–4 wraps). This prevents leaks at the threaded connection.
- Alignment: Use a level to ensure the arm is straight. An angled arm looks unprofessional and can cause stress on the connection.
Step 6: Pressure Test Before Closing Walls
Do not skip this step. Once the new plumbing is assembled, turn the water supply back on slowly.
- Inspection: Check every new joint for drips or moisture.
- Duration: Let the water run for at least 10–15 minutes. Sometimes small leaks only appear after pressure builds up.
- Fixing Leaks: If you see a leak, turn the water off immediately, drain the line, and re-solder or re-crimp the faulty joint.
Once confirmed leak-free, you can patch the drywall or retile the wall.
Common Mistakes to Avoid When Rerouting Shower Pipes
Even experienced DIYers make mistakes. Here are the most frequent errors and how to avoid them.
1. Ignoring Local Building Codes
Plumbing codes vary by state and municipality. Some areas require permits for any plumbing alteration. Failure to comply can result in fines or issues when selling your home. Always check with your local building department.
2. Mixing Metals Without Dielectric Unions
Connecting copper directly to galvanized steel causes galvanic corrosion, leading to rapid pipe failure. If you must connect dissimilar metals, use a dielectric union to separate them electrically.
3. Poor Support Structure
Loose pipes bang against studs when water flows, creating noise and eventual wear. Ensure all pipes are strapped tightly. If running pipes through wooden studs, use rubber grommets to cushion the pipe.
4. Over-Tightening Fittings
More torque does not mean a better seal. Over-tightening brass or plastic fittings can crack them. Hand-tighten plus a quarter-turn with a wrench is usually sufficient for threaded connections.
FAQ: Frequently Asked Questions
Can I reroute shower plumbing without tearing down the whole wall?
Yes, if you have access from the opposite side of the wall (such as a closet or hallway), you can do the work from there. If not, you will need to cut an access panel in the drywall or remove specific tiles, which can be patched later.
Do I need a permit to move a shower head?
In many US jurisdictions, moving a fixture requires a plumbing permit. This ensures the work meets safety codes. Check with your local city or county building department before starting.
What is the best pipe material for shower rerouting?
PEX (Cross-linked Polyethylene) is increasingly popular for DIYers because it is flexible, easy to cut, and requires no soldering. Copper is the traditional gold standard for durability but requires soldering skills. Avoid PVC for hot water lines inside walls.
How much does it cost to hire a plumber vs. DIY?
Hiring a licensed plumber typically costs between $200 and $500 for a simple relocation, depending on labor rates in your area. DIY costs are limited to materials, usually under $50, but carry the risk of personal error.
Why is my new shower head leaking at the wall?
This is usually due to insufficient Teflon tape or a cross-threaded connection. Remove the shower arm, clean the threads, apply fresh Teflon tape (clockwise), and reinstall carefully. Ensure the pipe inside the wall is not rotating while you tighten the arm.
Conclusion
Learning how to reroute plumbing for the shower head empowers you to customize your bathroom space without breaking the bank. By following this step-by-step guide, prioritizing safety, and adhering to local codes, you can achieve a professional-looking result. Remember, patience during the pressure testing phase is the key to long-term success.
