Shower diverters are handy devices that alter the water flow in a shower, transitioning it from the bathtub faucet to the showerhead. There are three primary types of shower diverters: knob, push-button, and lever, with knob diverters being the most prevalent.
The knob diverters, which are easy to operate, typically feature a single handle that regulates both water flow and temperature. Push-button diverters are gaining popularity due to their user-friendly nature. They typically have two buttons, one for hot water and the other for cold water.
On the other hand, lever diverters, while less common, find extensive use in commercial settings as they can be effortlessly operated with one hand. The market offers various types of shower diverters, each with its own set of advantages and disadvantages.
While the aforementioned three categories are generally recognized, there are over a dozen different types of shower valves available for selection. The most common types of shower diverters include:
1. Pressure-balanced shower diverters:
These diverters employ a valve system to maintain water pressure and prevent fluctuations. This ensures a consistent water stream, even if other water sources in the house are being used simultaneously. They balance the water pressure, compensating for any hot or cold water deficiencies.
Such diverters effectively maintain the water temperature, safeguarding against scalding. The pressure may vary significantly as the shower is used, particularly when multiple showerheads are in use. This feature is particularly noticeable in setups with multiple showerheads, contributing to a safe and comfortable showering experience.
2. Thermostatic shower diverters:
Thermostatic diverters rely on a thermostat to regulate water temperature. The thermostat monitors the water temperature and adjusts it as necessary to maintain a stable temperature. This feature proves beneficial in households with children or elderly family members who may be vulnerable to scalding.
If a significant and potentially dangerous temperature change is detected, the thermostatic diverter automatically halts the flow of hot water. Moreover, users can pre-set the water temperature, ensuring that the shower remains within the desired temperature range, promoting both comfort and environmental friendliness.
3. Single Valve (or T) diverter:
The single valve diverter represents the most common type, featuring a handle that controls both water flow and temperature. One advantage of this diverter is its relatively simple installation and ease of use. However, it can be a bit challenging to direct the water flow to the showerhead if the tub faucet is already activated.
4. Double Valve (or Cross) diverter:
A double valve diverter is equipped with two handles, one for hot water and the other for cold water. This type of diverter is gaining popularity due to its enhanced operability compared to single valve diverters.
5. Manual shower diverters:
Manual diverters require manual adjustment of water pressure and temperature. While this type may prove inconvenient if there are children or pets that enjoy playing in the shower, they tend to be more cost-effective than other options.
6. Dual-purpose shower diverters:
Also known as 2-way shower diverters, these versatile diverters come in various types. The standalone dual-purpose diverter, composed of a rough diverter valve body and a diverter trim, is particularly popular. It offers two features: the wild diverter valve body and the diverter trim.
These diverters lend a clean appearance to the shower and can be used with both a showerhead and a tub spout combination. They consist of two parts, namely the diverter unit and the main valve.
7. 3-Way Diverter:
A 3-way diverter boasts a separate diverter valve, enabling the unit to provide three functions instead of two. It encompasses one inlet, three outlets, and four port diverters, allowing for various configurations such as Showerhead+Rainhead+Body Spray or Showerhead+Tub Spout+Handheld.
8. Push Button Shower Diverter:
The push-button shower diverter comes pre-installed with a pressure balance valve. It lacks a dial function, limiting its control capabilities compared to other types. This diverter is operated using either a push & pull or push-only function, enabling complete shutoff or full flow activation. It is commonly employed in tub and shower combinations.
9. Integrated Diverter:
An integrated diverter is constructed within the handle of the existing shower valve trim. It may function through a slide-in mechanism or a dial. The diverter can either hang from the primary handle or be positioned on top or behind the control. This type offers versatility and functionality, surpassing that of push-button diverters, and occupies less space. However, it may be slightly more complex to operate.
10. Stacked Diverter:
In a stacked diverter, the shower valve component is combined with the main valve in a two-in-one configuration. It features a separate handle, either below or stacked on top of the main valve, available in the form of a knob or lever handle. The stacked diverter functions similarly to a standalone diverter but occupies less space.
11. Shower Arm Diverters:
Shower arm diverters are installed on the shower arm, forming a T-shaped valve controlled by a knob or lever handle. The water flows from the main showerhead, and the diverter can accommodate a handheld showerhead or other accessories. This type offers multiple showering options without the need for a complete dual-purpose diverter installation.
12. Diverter Tub Spout:
Diverter tub spouts are installed directly on the tub spout and feature a knob or lever handle to control water flow. These diverters are integrated into the tub faucet itself, providing direct flow by lifting the metal tab or valve. They enable water diversion to the showerhead or handheld showerhead, offering additional showering options without the requirement of a complete dual-purpose diverter installation.
13. Hot & Cold Diverter:
Hot & cold diverters are responsible for controlling the water temperature in the shower. Typically mounted on the wall near the showerhead, they consist of hot and cold water inlets. Similar to other diverters, they allow water diversion to the showerhead or handheld showerhead, providing multiple showering options without a complete dual-purpose diverter installation.
14. Four-Way Shower Diverter:
A four-way shower diverter valve offers ample options for users. It enables the simultaneous operation of any two outputs, such as a tub faucet, rain showerhead, handheld showerhead, or regular showerhead. It also allows for the complete diversion of water flow to a single output. However, proper alignment of all components is crucial for optimal functionality.
Shower diverters have been in use for many years, with their origins dating back to the early 1900s. Initially, diverters were developed to control water flow from the showerhead to the tub spout, allowing people to take showers without having to fill the tub first. In the 1950s, dual-purpose shower diverters emerged, facilitating water flow control between the showerhead, tub spout, and handheld showerhead. This innovation made it possible to take showers and rinse off in the tub without the need to fill it.
Selecting the right shower diverter for your needs involves considering various factors. These include your budget, available space, desired showerhead type, preference for simultaneous use of multiple showering options, handle type, and any special requirements like ADA compliance. Once you have evaluated these aspects, you can narrow down your options and find the ideal shower diverter for your home.
