PEX piping has become one of the most popular plumbing materials in modern homes. Flexible, affordable, and easy to install, it’s a top choice for many DIYers and pros alike. But if you’re remodeling your bathroom, you might be asking: can you use PEX for a shower faucet? The answer is yes — with a few important details to keep in mind.
Is PEX Allowed for Shower Faucets?
Yes, PEX is approved by plumbing codes in most areas for use with shower faucets. It connects easily to modern shower valves and handles hot water without issue. However, you’ll need to use the right fittings and follow code requirements.
Benefits of Using PEX for a Shower Faucet
PEX offers several advantages compared to copper or CPVC when used for shower plumbing:
- Flexibility: Bends around corners without needing elbows, reducing leak points.
- Faster installation: Easier to work with for DIYers than copper soldering.
- Cost-effective: Cheaper than copper and often quicker for plumbers to install.
- Durable: Resistant to corrosion and scale buildup.
- Quiet operation: Reduces water hammer compared to rigid pipes.
Limitations of PEX for Shower Plumbing
While PEX is versatile, there are some limitations to keep in mind:
- UV sensitivity: PEX cannot be exposed to sunlight — bad for outdoor showers without protection.
- Fitting compatibility: You must use crimp, clamp, or push-to-connect fittings rated for hot water.
- Local codes: Some municipalities still restrict PEX in certain applications — always check your local plumbing code.
- Wall bracing: Flexible pipe needs proper supports to prevent movement behind shower walls.
How to Use PEX for a Shower Faucet Installation
Here’s the general process for connecting PEX to a shower faucet:
- Choose a PEX-compatible shower valve. Most modern Moen, Delta, and Grohe valves have PEX inlet options.
- Run hot and cold PEX lines. Use red PEX for hot and blue for cold for easy identification.
- Secure the valve. Mount it solidly to blocking in the wall for stability.
- Use the right fittings. Crimp or clamp rings work best for secure connections.
- Pressure test the system. Always test before closing up your walls.
When to Use Copper Instead
Copper may still be better in some cases:
- If your local plumbing code requires it.
- For very high-heat applications (steam showers).
- When you want maximum rigidity behind walls.
