Unlocking the Mystery: What is a Diverter in a Shower?

In the realm of showers, there exists a vital component that often goes unnoticed, yet plays a significant role in the functionality and convenience of your bathing routine – the diverter. What exactly is a diverter in a shower? 

A diverter in a shower is a valve that directs water flow between the showerhead and another [lumbing fixture such as the bathtub faucet, handheld device, or water jets, allowing users to switch between them without the need for separate plumbing fixtures.

This article by a shower remodel specialist delves deep into the intricacies of this mechanism, unraveling its purpose, operation, and why it's essential for every modern bathroom.

What is a Diverter in a Shower?

Picture this: You're standing under a rejuvenating cascade of water, relishing the blissful sensation of a hot shower. Suddenly, you realize you need to rinse off your hair treatment or indulge in a refreshing rain shower. This is where the diverter steps in. 

Essentially, a diverter is a valve or mechanism installed in shower systems to control the flow of water between different outlets. It allows you to switch between various shower functions seamlessly, directing water to different fixtures such as the overhead shower, handheld showerhead, or bathtub spout.

Types of Shower Diverters

Shower diverters are critical components in a bathroom setup, allowing you to direct the flow of water between the showerhead and other outputs like a bathtub faucet or a hand-held shower. 

There are several types of shower diverters, each with its unique mechanism and application:

1. Tee Diverter

  • Mechanism: The tee diverter is the simplest type, incorporated into the tub spout. It's activated by pulling up a knob on the top of the spout, which blocks water from exiting through the tub spout and redirects it to the showerhead.

  • Usage: Best suited for basic bathtub and shower combinations without additional water outlets.

2. Two-Valve Diverter

  • Mechanism: This type of diverter is found in showers with dual faucet controls for hot and cold water. The diverter valve is located between the two controls and is turned to direct water flow to the showerhead or tub spout.

  • Usage: Ideal for setups where precise temperature control is desired, and there are separate outlets for the tub and the shower.

3. Three-Valve Diverter

  • Mechanism: In systems with three valves, two valves control the water temperature by mixing hot and cold water, while the third valve serves as the diverter. It is usually located in the center and, when turned, redirects water from the tub spout to the showerhead.

  • Usage: Common in older homes with separate hot and cold water controls, offering a clear choice between tub and shower.

4. Push-Button Diverter

  • Mechanism: A push-button diverter is a modern variation where a button, often located on the shower valve faceplate, is pressed to switch water flow from the tub spout to the showerhead.

  • Usage: Suitable for modern bathrooms looking for a sleek design with simple functionality.

5. Integrated Shower Diverter

  • Mechanism: Some modern shower systems integrate the diverter function within the shower's mixing valve. This setup allows you to control both the water temperature and the flow direction with a single handle or a series of buttons.

  • Usage: Ideal for new installations or remodels, offering a clean look and simplified user experience.

6. Bar Diverter Valves

  • Mechanism: Bar diverter valves are found in shower systems with a slide bar for a hand-held showerhead. The diverter is often a part of the slide bar assembly or the hand-held unit itself, allowing users to switch between the fixed showerhead and the hand-held shower.

  • Usage: Perfect for showers that require flexibility, such as those needing accessibility options or wanting the luxury of multiple showerheads.

Understanding the different types of shower diverters helps in choosing the right one for your bathroom, ensuring a functional and enjoyable shower experience. 

Each type serves a specific purpose and fits different plumbing configurations, so consider your bathroom's needs and preferences when selecting a diverter.

Selecting the Right Shower Diverter

Selecting the right shower diverter is crucial for ensuring that your bathroom's plumbing functions smoothly and meets your specific needs. 

Here are key considerations to keep in mind when choosing the best shower diverter for your bathroom:

1. Understand Your Bathroom's Plumbing Configuration: Assess whether your bathroom setup is more suited for a tub and shower combo or a separate tub and shower. This will help determine whether you need a basic tee diverter, a two-valve, a three-valve, or an integrated shower diverter. Consider the current plumbing layout, including the location of water supply lines and the type of fixtures installed. This information will guide you in choosing a diverter that fits seamlessly with your existing system.

2. Determine the Type of Diverter Needed: Tee Diverter: Ideal for simple tub and shower combinations where the diverter is integrated into the tub spout.

  • Two-Valve Diverter: Suitable for setups where you want separate controls for hot and cold water along with the diverter function.

  • Three-Valve Diverter: Best for older homes with separate taps for hot and cold water, requiring a dedicated diverter valve to switch between tub and shower.

  • Integrated Shower Diverter: Perfect for modern bathrooms looking for a streamlined look with a single handle or dial controlling both temperature and diversion.

3. Consider the Material and Finish: Opt for materials that are durable and resistant to corrosion, such as brass or stainless steel, to ensure longevity. Choose a finish that matches or complements your existing bathroom fixtures and decor. Common finishes include chrome, brushed nickel, and oil-rubbed bronze.

4. Ease of Installation and Maintenance: If you're planning a DIY installation, look for a diverter with straightforward installation instructions and minimal required tools. Some diverters can be more complex to install, necessitating professional assistance.

5. Style and Functionality: The style of the diverter should align with the overall aesthetic of your bathroom. There are diverters available to fit any design scheme, from traditional to contemporary. Evaluate the functionality you need, such as the ability to divert water to multiple showerheads or a hand shower. Some diverters offer more advanced features, including water-saving functions and compatibility with smart home systems.

6. Consult with a Professional: If unsure about the best type of diverter for your bathroom, consult with a plumbing professional. They can provide valuable insights based on your specific plumbing setup and personal preferences.

7. Budget: Consider your budget when selecting a shower diverter. While it's important to choose a durable and functional diverter, there are options available at various price points to suit different budgets.
