A shower diverter is a simple yet essential part of your bathroom’s plumbing system. It directs water between different outlets such as an overhead shower, hand shower or spout. When it works well, you barely notice it. When it doesn’t, it can make showering frustrating. This guide breaks down everything you need to know so you can choose, install and maintain a diverter confidently.
1. What Is a Shower Diverter and How It Works
A shower diverter is a valve that controls how water flows between different shower outlets. When you turn or pull the diverter, the internal mechanism opens or blocks specific channels, allowing you to direct water exactly where you want it to go such as the overhead shower, hand shower, spout or any additional outlet in your setup.
Diverters make it possible to enjoy multiple shower functions using a single control, which is why they are essential in modern bathrooms.
Where Diverters Are Installed
- Inside the wall in concealed shower systems
- Built into a bath spout in basic or older setups
- Integrated into premium mixers in luxury shower configurations

2. Types of Shower Diverters
Modern diverters are best understood by the number of outlets they control, instead of only “2-way” or “3-way” terms used earlier. Here’s a simple breakdown to help you choose the right one.
2-Way Diverter
Controls two outputs. The most common combinations include:
- Overhead shower and hand shower
- Spout and showerhead
It lets you switch between two functions but not run them simultaneously.
3-Way Diverter
Controls three outputs, typically:
- Overhead shower
- Hand shower
- Spout
Ideal for regular homes that want multiple showering options without going into high-end complexity.
4-Way Diverter
Adds a fourth function such as:
- Body jets
- Secondary hand shower
- Additional spray outlet
Perfect for slightly more advanced setups with extra comfort features.
5-Way Diverter
Usually found in spa-inspired bathrooms. Supports features like:
- Rain shower
- Hand shower
- Cascade / waterfall outlet
- Body jets
- Spout or mist spray
6-Way Diverter
Suitable for luxury spaces with many water experiences. It may control:
- Rain shower
- Hand shower
- Body jets
- Side sprays
- Waterfall outlet
- Spout or mist function
Tee / Spout Diverter
A simple diverter built into the spout itself. Pulling the knob redirects water from the spout to the showerhead. Often seen in older bathrooms.
Thermostatic Diverters
Combine flow selection with temperature stability. They maintain a steady, pre-set water temperature, which is highly useful for children and elderly family members.
3. How to Choose the Right Shower Diverter
The best diverter for your home depends on:
- Number of outlets
- Water pressure
- Type of shower system

5. Common Shower Diverter Problems
Water Drips From Spout While Showering
Likely a worn washer or scale buildup. Cleaning or replacing the washer usually solves it.
Diverter Handle Feels Stuck
Often caused by mineral deposits. Remove the handle and clean the cartridge.
Weak Water Flow
Check for clogged aerators or a blocked diverter chamber.
Temperature Issues
A faulty thermostatic cartridge may be the cause.
Troubleshooting Table
| Issue | Cause | Solution |
| Shower won’t switch outlets | Diverter blocked | Clean the internal cartridge |
| Water leaking behind wall plate | Loose fitting | Tighten or reseal |
| Sudden temperature shifts | Faulty thermostat | Replace cartridge |
| Low pressure from overhead shower | Scale inside pipes | Descale diverter system |
6. Maintenance Tips for Long-Lasting Performance
- Clean the diverter plate every week
- Avoid abrasive cleaners
