Common Shower Valve Service Questions

How long shower valves last depends on the type you have, how much use it gets, the hardness of your water, and whether the valve was installed correctly. Good-quality brass shower valves are sturdy and last around 20 years, while lower-quality plastic valves last 4 to 5 years. Since shower valves wear out over time, you can proactively replace yours after 15 years or whenever you update your showerhead.

You cannot replace a shower valve without turning off the water. Always turn your water off before doing any kind of plumbing work—and this project is no exception. Turning off the water is a best practice for personal safety and to keep things in your home dry.

Shower mixing valves are usually located behind the shower handles. Accessing the mixing valve is difficult for a DIYer, so it’s best to call a pro if you think this could be the issue. A plumbing repair expert has the right tools and knowledge to easily access the valve, diagnose the issue, and recommend repairs if needed.

Shower valve replacement costs an average of $350, and most homeowners pay between $150 and $550. The price will depend on labor costs in your area, as well as the type of diverter valve you choose. A simple diverter valve could cost just $20 in materials, while a high-end mixing valve for better temperature control can cost $350.

There are a few reasons your diverter valve may not be fully diverting. Blockages from mineral buildup are common, but if your diverter is older, it may be suffering from normal wear and tear. Components can wear down or crack. In some cases, the cartridge may be defective, and you’ll need to replace it.
